Detailed Description

Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment, and the embodiments described below are only some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solution described in the embodiments of the present application can be applied to various wireless communication networks, such as a Code Division Multiple Access (CDMA) network, a Time Division Multiple Access (TDMA) network, a Frequency Division Multiple Access (Frequency Division Multiple Access FDMA) network, an Orthogonal FDMA network, an Orthogonal Frequency Division Multiple Access (OFDMA) network, an FDMA network, and the like. A CDMA network may implement a wireless technology such as universal terrestrial radio access, CDMA2000, etc. TDMA networks may implement wireless technologies such as Global System for mobile communications (GSM). An OFDMA network may implement wireless technologies such as evolved UTRA (universal Radio access) (E-UTRA), Ultra Mobile Broadband (UMB), etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are new versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE-A and GSM are described in a document entitled "third Generation partnership project" organization. The solutions described herein may be used with the wireless networks and wireless technologies mentioned above, as well as with other wireless networks and wireless technologies. For clarity, the embodiments of the present application will be described in terms of an LTE network.

Fig. 1 is a schematic structural diagram of a wireless communication network in an embodiment of the present application, which may be an LTE network or other wireless networks, where the wireless communication network 100 includes a Mobility Management Entity (MME) 101, a base station 102 (e.g., an evolved Node-B (eNode-B)), and a first UE111 and a second UE 112. The base station 102 may operate with a first UE111, a second UE112 to wirelessly communicate with each other in the wireless communication network 100. The range of the circle in fig. 1 is the range of the cell in which the base station 102 is located, i.e., the effective communication range of the base station 102, i.e., the cell 104.

The first UE111 and the second UE112 may be one or more of a cellular phone (e.g., a smartphone), a tablet, an e-reader (e.g., an e-book reader), a laptop computer, a desktop computer, a personal computer, a server, a personal digital assistant, a network router, or other device.

The MME101 may communicate with the base station 102 to track UEs within the cell 104 where the base station 102 is located, and perform data transmission with the UEs.

The wireless communication network has a DRX function, and specifically, the DRX function is realized by a DRX cycle, where the DRX function is: the UE enters a DRX sleep period when there is no data to transmit, and enters a DRX active period when there is data to transmit, so as to reduce power consumption of the UE, that is, the DRX cycle includes the DRX sleep period and the DRX active period, in the DRX active period, the UE is in an active state and monitors a Physical Downlink Control Channel (PDCCH), and in the DRX sleep period, the UE is in a sleep state and does not monitor the PDCCH. After the UE accesses the base station, the base station sends a Radio Resource Control (RRC) message to the UE, and after receiving the RRC message sent by the base station, the UE reads a DRX cycle carried by the RRC message and maintains a DRX timer according to the read DRX cycle, where the DRX timer periodically monitors a paging message in a physical downlink Control channel based on the DRX cycle according to a protocol. It can be understood that the UE can listen to the paging message sent by the base station and establish a call connection during the active period of the DRX cycle.

In order to better understand the technical solution in the embodiment of the present invention, specific scenarios are exemplified as follows: the third UE calls out a call and sends the generated paging message to a base station a of a cell where the third UE is located, the base station a sends the paging message to an MME connected to the base station a, the MME sends the paging message to an MME101 in fig. 1, the MME101 broadcasts the paging message, if the paging message includes an identifier of the first UE111, if a DRX active period of the first UE111 overlaps with a time period where a preset paging duration of the paging message is located, the first UE111 monitors the paging message in the DRX active period and feeds back a paging response message, thereby establishing a call connection between the third UE and the first UE 111. If the DRX active period of the first UE111 does not overlap with the time period of the preset paging duration of the paging message, the first UE111 cannot monitor the paging message and cannot establish a communication connection with a third UE, which is that the first UE111 fails to be paged. It should be noted that the scenario is one scenario in which the user cannot make a call, and in addition, there are other possibilities that the user cannot make a call, which is not limited herein. The preset paging duration refers to the effective duration of the paging message.

For better understanding of the technical solution in the embodiment of the present application, please refer to fig. 2, which is a schematic flow chart of a method for adjusting a DRX cycle in the embodiment of the present application, including:

step 201, acquiring the number of times of paging failure of each user equipment UE accessed to a cell of a base station in a preset time period;

in the embodiment of the present application, the method for adjusting the DRX cycle described above is implemented by an apparatus for adjusting the DRX cycle (hereinafter, referred to as an adjusting apparatus for short), where the adjusting apparatus is a part of the base station, and specifically may be an application program in a storage space of the base station, and a processor of the base station may read the adjusting apparatus from the storage space and execute the reading to implement each step in the method for adjusting the DRX cycle in the embodiment.

Wherein a UE will access a base station in a cell after entering the cell in order to be able to access the wireless communication network, and it can be understood that each time the UE enters a new cell, it needs to perform an access operation again.

The adjusting device may determine each UE that has accessed the cell in which the base station is located, and determine the number of times that each UE has failed to be paged within a preset time period. The paging failure means that the base station of the cell broadcasts a paging message of the UE, but the UE does not monitor the paging message within a preset paging duration of the paging message and does not respond in time, resulting in a paging failure.

The preset time period may be a time period elapsed from a current time point, for example, may be set to be within 1 hour, and in an actual application, the preset time period may be set according to needs, and is not limited herein.

Step 202, if there is a target UE with a paging failure number greater than or equal to a preset number threshold, performing cycle shortening processing on a first DRX cycle used by the target UE to obtain a second DRX cycle of the target UE;

step 203, sending the second DRX cycle to the target UE, where the second DRX cycle is used for discontinuous monitoring of a paging message performed by the target UE on a physical downlink control channel.

In this embodiment of the present application, the adjusting apparatus is preset with a condition for determining whether to shorten the DRX cycle of the UE, that is, determining whether there is a target UE whose number of times of failed paging is greater than or equal to a preset number threshold in the preset time period, where the preset number threshold may be set as needed, and may be, for example, 1 or 2.

In each UE of the cell in which the base station is located, if there is a UE whose number of times of paging failure is greater than or equal to a preset number threshold, the UE may be referred to as a target UE, and the adjusting device performs a cycle shortening process on a first DRX cycle used by the target UE, where the first DRX cycle is a DRX cycle currently used by the target UE, and a second DRX cycle of the target UE can be obtained, which is the adjusted DRX cycle.

Further, the adjusting device sends the second DRX cycle to the target UE, and after receiving the second DRX cycle, the target UE replaces the existing DRX cycle with the second DRX cycle and monitors the PDCCH according to the second DRX cycle.

In the embodiment of the application, for the target UE of which the paging failure frequency is greater than or equal to the preset frequency threshold, the DRX period of the target UE is shortened, so that the period of the target UE for monitoring the paging message is shortened, the monitoring frequency in the same time is increased, the probability of the target UE for monitoring the paging message can be effectively improved, and the call-through rate is improved.

Referring to fig. 3, another schematic diagram of a method for adjusting a DRX cycle in the embodiment of the present application is shown based on the embodiment shown in fig. 2, and includes:

step 301, acquiring the number of times of paging failure of each user equipment UE which has accessed to a cell where a base station is located within a preset time period;

in the embodiment of the present application, the content described in step 301 is similar to the content described in step 201 in the embodiment shown in fig. 2, and is not described herein again.

Further, the manner in which the adjusting apparatus obtains the number of times of failed paged will be described in detail below:

if receiving a paging message sent by an MME, an adjusting device broadcasts the paging message, the paging message has preset paging duration, and a call connection can be established only when the paging message is responded within the preset paging duration, wherein the paging message comprises an identifier of a paged UE. It can be understood that if the UE in the active period in the cell monitors the paging message, the UE reads the identity of the paged UE included in the paging message and matches the identity with its own identity to determine whether the paging message needs to be responded. The UE identifier may be an International Mobile Subscriber Identity (IMSI) of the UE, or other identifier that can uniquely identify the UE, which is not limited herein.

If the paging response message fed back by the paged UE is not received within the preset paging duration, the adjusting device records the time point of the paging failure of the paged UE based on the identifier of the paged UE, and counts the number of the time points of the paging failure of the paged UE within the preset time period as the number of the paging failure times of the paged UE.

Step 302, if there is a target UE with the number of times of failed paging greater than or equal to a preset number threshold, acquiring an actual access number of the UE having accessed the cell where the base station is located;

step 303, searching a corresponding relation between a preset access number and a shortening ratio of a DRX period, and determining a target shortening ratio corresponding to the actual access number;

in the embodiment of the present application, if there is a target UE that has failed to be paged for a number of times that is greater than or equal to a preset number threshold, the adjusting device will obtain an actual access number of the UE that has accessed the cell in which the base station is located. Therefore, the base station may count the actual access number of the UEs that have accessed the base station at a certain time, for example, if 100 UEs currently access the base station a, the actual access number of the base station a is 100.

In the embodiment of the present application, a correspondence relationship between the access number and the shortening ratio of the DRX cycle is preset, and in general, the larger the access number is, the more resources are required, and the greater the probability that the UE in the cell is called unsuccessfully is. The adjusting device may search for a correspondence between the access number and a reduction ratio of the DRX cycle, determine a target reduction ratio corresponding to the actual access number, and further obtain a second DRX cycle of the target UE using the obtained target reduction ratio and the first DRX cycle.

Step 304, obtaining a second DRX period of the target UE by using the target shortening ratio and the first DRX period;

in this embodiment, the adjusting device obtains a second DRX cycle of the target UE by using the obtained target reduction ratio and the first DRX cycle. And the first DRX period is the DRX period currently used by the target UE, and the second DRX period is shortened according to the target shortening proportion, so that the second DRX period is smaller than the first DRX period.

It should be noted that, since the DRX cycle includes the DRX active period and the DRX dormant period, when the first DRX cycle is processed according to the target reduction ratio, there may be at least two processing manners, one of which is that the DRX active period in the first DRX cycle is multiplied by the target reduction ratio to obtain a reduced DRX active period, and the DRX dormant period in the first DRX cycle is multiplied by the target reduction ratio to obtain a reduced DRX dormant period, and the reduced DRX active period and the DRX dormant period are spliced to obtain the second DRX cycle, it can be understood that this manner can effectively increase the frequency of the DRX active period, the monitoring frequency for the PDCCH can be made higher by increasing the frequency, and since the preset paging duration of the normal paging message is longer, the probability of monitoring the paging message within the preset paging duration can be increased by increasing the monitoring frequency, so as to respond in time and effectively improve the call completing rate. In another feasible implementation manner, the target shortening ratio can be multiplied by the first DRX cycle to obtain the duration of the second DRX cycle, and at the same time, the duration of the DRX active period in the first DRX cycle is determined, the duration of the DRX active period in the second DRX cycle is set to be the same as the duration of the DRX active period in the first DRX cycle, and other times except the DRX active period in the second DRX cycle are used as DRX dormant periods.

In order to better understand the technical solution in the embodiment of the present application, please refer to fig. 4a, which is a schematic diagram of a first DRX cycle in the embodiment of the present application, and please refer to fig. 4b, which is a schematic diagram of a second DRX cycle in the embodiment of the present application, and the second DRX cycle is obtained after the first DRX cycle is shortened according to a target shortening ratio, wherein the target shortening ratio is 0.5, that is, the second DRX cycle is half of the first DRX cycle, and as can be seen from a comparison between fig. 4a and fig. 4b, the second DRX cycle is shortened by half relative to the first DRX cycle, and the frequency of monitoring the PDCCH is increased, for example, if monitoring is performed twice in a time period originally, and after the shortening, the same time can be monitored four times, so that the probability of monitoring the paging message can be effectively increased, and the paging rate can be improved. And the DRX activation period in the second DRX period is the same as the activation period of the first DRX period in duration, and the duration of the DRX activation period is kept unchanged under the condition that the period is shortened by half, which is equivalent to the increase of the DRX activation period, so that the probability of monitoring the paging message can be further improved, and the call completing rate can be further improved.

It can be understood that, when the first DRX cycle is shortened according to the target shortening ratio to obtain the second DRX cycle, the duration of the DRX active period in the second DRX cycle can be further increased according to the ratio, so that the probability of monitoring the paging message when monitoring the PDCCH can be further improved by increasing the DRX active period of the second DRX cycle, and the call-through rate can be improved.

It should be noted that, in the embodiment of the present application, increasing the probability of monitoring the paging message refers to the probability of the UE monitoring the paging message that includes the identifier of the UE as the called UE.

Step 305, sending the second DRX cycle to the target UE, where the second DRX cycle is used for discontinuous monitoring of a paging message performed by the target UE on a physical downlink control channel.

In this embodiment, after obtaining the second DRX cycle, the adjusting apparatus may send the second DRX cycle to the target UE, so that the target UE replaces the first DRX cycle currently used by the target UE with the second DRX cycle, and perform a DRX function according to the DRX active period and the DRX dormant period in the second DRX cycle, so as to be able to monitor whether there is a paging message of the target UE in the PDCCH during the DRX active period and enter the dormant state during the DRX dormant period, so as to save power consumption.

It is to be understood that, in order to prevent the second DRX cycle after being shortened from being too short in duration and consuming a large amount of power of the UE, a DRX cycle minimum value of the target UE may be preset, wherein the DRX cycle minimum value may be determined based on device parameters of the target UE, the device parameters including a device model, a battery model, a manufacturer, and the like. After obtaining the second DRX cycle each time, the adjusting apparatus obtains the minimum DRX cycle of the corresponding target UE, compares the second DRX cycle with the minimum DRX cycle, and when the minimum DRX cycle is smaller than or equal to the second DRX cycle, indicates that the adjustment of the DRX cycle is within an acceptable range, the adjusting apparatus continues to perform step 305, and when the minimum DRX cycle is greater than the second DRX cycle, indicates that the currently obtained second DRX cycle is not suitable for the target UE, at this time, the adjusting apparatus sends the minimum DRX cycle to the target UE, so that the target UE can perform the DRX function according to the minimum DRX cycle. And further, marking the target UE that the target UE is not to perform DRX period adjustment any more.

It can be understood that, after the target UE performs monitoring according to the second DRX cycle, the adjusting apparatus may zero the number of times that the target UE fails to be paged within a preset time period, and record a time point when the DRX cycle of the target UE is shortened. And the adjusting apparatus will return to step 301, that is, it will continue to acquire the number of times of failed paging of each UE accessing the cell of the base station within the preset time period, and if the target UE is adjusted once, it is detected that the target UE has failed paging, at this time, in order to improve the call-through rate of the target UE, the adjusting apparatus will continue to shorten the DRX cycle according to the technical scheme in the embodiment shown in fig. 3.

Further, since there may be a case where the DRX cycle of the target UE is shortened multiple times, when determining the target shortening ratio of the target UE, the adjustment number of the DRX cycle of the target UE in a second preset time period, which is longer than the above preset time period, for example, the second preset time period may be 24 hours, may be further referred to, and since the time point of shortening the DRX cycle of the target UE each time is recorded, the adjustment number in the second preset time period may be effectively determined. Wherein, the base station is preset with a corresponding relationship among the access number, the shortening ratio of the DRX cycle, and the adjustment number, so that a target shortening ratio corresponding to the actual access number and the adjustment number within the second preset time can be determined, and step 304 and step 305 can be continuously executed to implement the adjustment.

In the embodiment of the application, for the target UE of which the paging failure frequency is greater than or equal to the preset frequency threshold, the DRX period of the target UE is shortened, so that the period of the target UE for monitoring the paging message is shortened, the monitoring frequency in the same time is increased, the probability of the target UE for monitoring the paging message can be effectively improved, and the call-through rate is improved. Furthermore, when the DRX period is shortened, the duration of the DRX activation period can be kept unchanged, and the DRX dormant period is shortened, so that the actual duration of monitoring can be further improved under the condition of improving the monitoring frequency, the probability of monitoring the paging message is effectively improved, and the call-through rate is further improved. And the adjustment of the DRX period can be effectively controlled by setting the minimum value of the DRX period.

On the basis of the embodiments shown in fig. 2 and fig. 3, the following steps may be further performed:

step A, when the fact that the actual access number of the UE which has accessed to the cell of the base station is greater than a preset first access number threshold value is monitored, determining a first UE set of which the DRX period is not adjusted in the preset time period;

step B, updating the DRX period of each UE in the first UE set according to a preset period shortening ratio to obtain the updated DRX period of each UE in the first UE set;

and step C, sending the updated DRX period to the corresponding UE in the first UE set.

In this embodiment of the present application, the DRX cycle adjustment is performed on the target UE whose number of times of call failure is greater than or equal to the preset number threshold in the preset time period described in the embodiments shown in fig. 2 and fig. 3, in a feasible implementation manner, in order to prevent occurrence of other UEs whose number of times of call failure is greater than or equal to the preset number threshold in the preset time period, the adjustment apparatus may also perform DRX cycle adjustment on other devices that have accessed to the cell where the base station is located, so as to avoid a problem of low call completion rate of the other UEs.

Specifically, the adjusting device monitors an actual access number of UEs accessing a cell in which the base station is located, and determines a first UE set with a DRX cycle not adjusted in a preset time period when the actual access number is greater than a preset first access number threshold, for example, if the actual access number of UEs accessing the cell in which the base station is located is 100, and 20 of them are adjusted in the preset time period, the first UE set includes the remaining 80 UEs that are not adjusted.

The adjusting device updates the DRX period of each UE in the first UE set according to the preset period shortening ratio to obtain the updated DRX period of each UE in the first UE set, and sends the updated DRX period to the corresponding UE in the first UE set.

And further, after the DRX cycle of each UE in the first UE set is adjusted, the adjusting device will continue to monitor the actual access number of the UE that has accessed the cell in which the base station is located, and when it is monitored that the actual access number decreases to a preset second access number threshold, determine a second UE set by using the first UE set, where the second UE set is a set of UEs in the first UE set that have not disconnected the network connection with the base station. For example, if the first set of UEs includes UEs 1-10, wherein UEs 5-10 disconnect the network connection with the base station (including two cases, one is not to re-access the base station after disconnecting the network connection with the base station, and the other is to re-access the base station after disconnecting the network connection with the base station, and a new DRX cycle is used), it is determined that the second set of UEs includes UEs 1-4. And the adjusting device restores the DRX period of each UE in the second UE set to be an initial DRX period and sends the corresponding initial DRX period to each UE in the second UE set, wherein the initial DRX period is the DRX period determined by the base station when the UE just accesses the network where the base station is located.

In the embodiment of the application, the DRX cycle of the target UE can be adjusted based on the number of times of call failure in a preset time period, and the DRX cycle of the UE in the cell can be uniformly adjusted based on the actual access number of the cell where the base station is accessed, so that the adjustment of the DRX cycle can be comprehensively realized, the monitoring frequency is effectively improved, and the call completing rate is improved.
