Description

Method, device and system for radio resource control connection

technical field

The present invention relates to the radio access technology in the mobile communication system, in particular to a method, device and system for performing radio resource control (RRC) connection.

Background technique

Spectrum resources are important resources in Wideband Code Division Multiple Access (WCDMA) systems, and the division of available frequency bands is constantly evolving with the development of communication protocols. The Third Generation Partnership Project (3GPP) technical standard TS25.101 divides available frequency bands as shown in Table 1.

Table 1

As shown in Table 1, the R5 protocol supports 3 frequency bands: BAND I~III, the R6 protocol supports 6 frequency bands: BAND I~BAND VI, and the R7 protocol supports 9 frequency bands: BAND I~IX. In the R5 protocol, since each frequency band has no overlapping portion, the frequency band to which it belongs can be determined according to the frequency band point. After the R6 and R7 protocols introduce multiple frequency bands, some frequency bands overlap, and because the protocol does not specify the uplink and downlink frequencies of the broadcast cell in the system message, the user terminal (UE) cannot use the currently scanned downlink The frequency point reverses the uplink frequency point. In order to solve this problem, the R6 protocol introduces the frequency band indication information element in the system message type 5 to indicate the frequency band used by the cell, so that the UE can calculate the uplink frequency point according to the scanned downlink frequency point and frequency band indication. Here, the frequency band point is referred to as the frequency point for short.

When the UE is in idle mode, if the UE's Non-Access Stratum (NAS) requests to establish a signaling connection, the UE will initiate an RRC connection establishment request to the RNC. FIG. 1 is a schematic diagram of a signaling flow for establishing an RRC connection in the prior art. Referring to Figure 1, the connection establishment process includes the following steps:

Step 1: UE sends RRC connection request message (RRC CONNECTIONREQUEST) to RNC;

Step 2: After the RNC performs resource allocation, it sends an RRC connection establishment message (RRCCONNECTION SETUP) to the UE;

Step 3: The UE responds to the RNC with an RRC connection establishment complete message (RRC CONNECTIONSETUP COMPLETE).

According to the provisions of the 3GPP TS25.306 protocol version R6, the UE can describe the frequency band capabilities supported by the UE through two sets of information elements: the radio access capability extension (radio access capability extension) and the measurement capability extension (Measurementcapability extension), that is, the UE's The multi-band capability, and put these two groups of information elements in the RRC CONNECTION SETUP COMPLETE message to report to the RNC, so that the RNC can obtain the multi-band capability information of the UE.

In order to improve the access success rate of the UE, cells in multiple frequency bands are usually used for coverage in the hotspot area, and the cells are inter-frequency adjacent cells. When the load of a cell is too high, the RRC connection will fail. At this time, the radio network controller (RNC) can control the UE to access other neighboring cells. According to the protocol, the RNC can control the UE to send inter-frequency measurement reports to the cells supported by the UE's frequency band capability according to the UE's multi-band capability obtained during the RRC connection establishment process, and control the UE to complete the handover according to the measurement report; The configured frequency band information of adjacent cells directly controls the UE to initiate a handover to a cell supported by the UE's frequency band capability without using a measurement report. The latter is called direct retry.

Direct retry can be initiated during RRC connection phase or RAB establishment phase. For direct retry, the RNC can notify the UE of the frequency point information of the inter-frequency adjacent cell supported by the UE's frequency band capability in the RRC CONNECTIONSETUP message according to the configuration information of the inter-frequency adjacent cell of the currently accessed cell, thereby establishing the RRC connection in the RRC CONNECTIONSETUP message. on the inter-frequency adjacent cell. In addition, if the RNC rejects this RRC connection, it can also notify the UE of the frequency point information of the inter-frequency adjacent cell or inter-system adjacent cell supported by the UE's frequency band capability in the RRC CONNECTTION REJECT message to help the UE choose An appropriate frequency point re-initiates the RRC signaling connection, and this process is called redirection.

However, it can be seen from Figure 1 that when the RNC sends the RRC CONNECTION SETUP message or RRC CONNECTION REJECT message to the UE, the frequency band capabilities supported by the UE have not yet been reported. Therefore, when the UE cannot establish a signaling connection with the current access cell, the direct When retrying or redirecting, because the RNC has not obtained the multi-band capability of the UE, the RNC cannot determine the cell belonging to the frequency band supported by the UE's frequency band capability, and thus cannot complete the direct retry or redirection.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

The main idea of the embodiment of the present invention is to enable the RNC to obtain the UE's multi-band capability information during the RRC connection establishment phase by carrying the UE's multi-band capability information in the RRCCONNECTION REQUEST message sent by the UE to the RNC, so that when the RRC connection fails, The target cell for direct retry or redirection can be determined according to the acquired UE multi-band capability information.

When the RRC connection fails, the RNC can notify the UE of the frequency point information of the inter-frequency neighboring cells supported by the UE's frequency band capability through the RRC CONNECTION SETUP message, or the inter-frequency neighboring cells supported by the UE's frequency band capability through the RRCCONNECTION REJECT message Or notify the UE of the frequency point information of the neighboring cell of the different system. Preferably, the RRC CONNECTION SETUP message can be sent first, and the UE can be controlled to initiate a direct retry. When the number of retries has reached the maximum retry threshold, the RRC CONNECTION REJECT message can be sent . Control the UE to initiate redirection.

In the following two embodiments, the above-mentioned preferred implementation manner is taken as an example, and the method and system for RRC connection of the present invention are described in detail respectively.

Embodiment one:

FIG. 2 is a schematic flowchart of a method for performing an RRC connection in Embodiment 1 of the present invention. Referring to Figure 2, the method comprises the following steps:

Step 201: Carry the UE's multi-band capability information in the RRC CONNECTION REQUEST message.

In this embodiment, the RRC CONNECTION REQUEST message may be extended to carry the multi-band capability information of the UE. The structure of the existing RRC CONNECTION REQUEST message is shown in Table 2:

Information Element/Group name (InformationElement/Group name) Necessity Multi-valued (Multi) Type (Type and reference) Semantics description Version Message Type Mandatory (MP) Message Type Radio Bearer IEs ... .. UE Information Element Groups (UE IEs) ... .. Measurement IEs ... ...

Table 2

In this embodiment, an information element (IE: Information Elements) representing the multi-band capability information of the UE can be added to the structure shown in Table 2. In the following description, the newly added information element representing the multi-band capability information of the UE is called Multi-band cells. It can be seen from Table 1 that there are currently 9 frequency bands supported by relevant protocols. Therefore, 9 bits (bits) can be allocated to the multi-band cell, so that each bit corresponds to a frequency band, and the bit value and whether to support the frequency band are specified. In this way, the multi-band capability of the UE can be carried in the RRCCONNECTION REQUEST message. For example, it may be stipulated that when a certain bit has a value of 1, it means that the UE supports the frequency band corresponding to the bit, so that the multi-band capability of the UE can be determined according to the value of the corresponding bit.

Since the RRC CONNECTION REQUEST message is accessed through a random access channel (RACH), the size of the message has a great impact on the performance of the system.

There are mandatory cells and optional cells in the existing RRC CONNECTION REQUEST message. The size of the mandatory cells is 40 bits. If all the optional cells already defined are added, the size of the RRC CONNECTION REQUEST message is 300bit. Generally, the transmission format of the RACH channel configuration is 1×168, wherein, 1 represents the number of transport blocks (TB), and 168 represents the size of a TB block, and the unit is bit. Therefore, the existing RRC connection request message usually requires 1 to 2 TB blocks for data transmission. Considering the scalability of the newly added multi-band information element in this embodiment and the impact on wireless access performance, preferably, 16 bits may be allocated to the multi-band information element to correspond to each frequency band. Of course, the length of the multi-band cell can also take other values under the premise of taking into account the scalability and the impact on wireless access signal performance.

Assuming that when a certain bit takes a value of 1, it means that the UE supports the frequency band corresponding to this bit, then in this step, the UE can set the corresponding bit in the multi-band information element to 1 according to the frequency band it supports.

Step 202: UE sends RRCCONNECTION REQUEST message carrying UE multi-band capability information to RNC.

Step 203: When the RNC fails to apply for cell resources from the cell currently accessed by the UE, continue to execute step 204.

In this step, if the resource of the UE currently accessing the cell is insufficient, for example, there is no available code resource in the currently accessing cell or the power of the cell is overloaded, the connection cannot be established. In this case, the RNC can control the UE to directly retry or redirect.

In this step, the cell resources applied by the RNC to the cell currently accessed by the UE include radio link resources and other resources.

Step 204: Determine whether there is an inter-frequency neighbor cell in the cell currently accessed by the UE, and if so, proceed to step 205; otherwise, end the method flow of this embodiment.

In this step, if there are inter-frequency neighboring cells in the currently accessed cell of the UE, the RNC will control the UE to initiate direct retry or redirection to the inter-frequency neighboring cells supported by the UE's frequency band capability; otherwise, the method flow of this embodiment will end .

Step 205: Determine whether the number of retries has reached the maximum threshold number of retries, if not, proceed to step 206; if reached, proceed to step 208.

In this step, when the RNC determines that there are inter-frequency neighboring cells in the cell currently accessed by the UE, it preferentially controls the UE to initiate a direct retry, and controls the UE to initiate a redirection when the number of retries has reached the maximum retry threshold.

Step 206: RNC sends to UE an RRC CONNECTION SETUP message carrying frequency point information of inter-frequency neighboring cells supported by UE's frequency band capability.

In this step, the RNC can determine the inter-frequency adjacent cells supported by the UE's frequency band capability according to the configuration information of the inter-frequency adjacent cells of the UE's current access cell and the UE's multi-band capability information obtained from the RRC CONNECTION REQUEST message. The inter-frequency neighboring cell is used as the target cell for the direct retry, and the frequency information of the inter-frequency neighboring cell is notified to the UE through the RRC CONNECTION SETUP message, so that the UE can initiate a direct retry to the target cell.

Step 207: The UE initiates a direct retry to the target cell of the direct retry.

In this step, the UE can obtain the frequency point information of the target cell for direct retry through the frequency point information in the RRC CONNECTION SETUP message, and initiate a direct retry to the target cell according to the existing direct retry related methods.

Step 208: RNC sends to UE an RRC CONNECTION REJECT message carrying frequency point information of inter-frequency adjacent cells or inter-system adjacent cells supported by UE's frequency band capability.

In this step, the RNC can determine the frequency band capability of the UE according to the configuration information of the inter-frequency adjacent cell or the configuration information of the inter-system adjacent cell of the cell currently accessed by the UE, and the multi-band capability information of the UE obtained from the RRC CONNECTION REQUEST message. Support inter-frequency adjacent cell or inter-system adjacent cell, take the inter-frequency adjacent cell or inter-system adjacent cell as the target cell for redirection, and pass the frequency point information of the inter-frequency adjacent cell or inter-system adjacent cell through the RRC CONNECTION REJECT message The UE is notified so that the UE can initiate redirection to the target cell.

Step 209: The UE initiates redirection to the redirection target cell.

In this step, the UE can obtain the frequency point information of the redirected target cell through the frequency point information in the RRC CONNECTION REJECT message, and initiate redirection to the target cell according to the existing redirection related methods.

So far, the method flow of this embodiment is ended.

It can be seen from the above-mentioned embodiments that the embodiment of the present invention carries the multi-band capability information of the UE in the RRCCONNECTION REQUEST message sent by the UE to the RNC, so that the RNC can obtain the multi-band capability information of the UE during the RRC connection establishment phase, so that when the RRC connection fails , the target cell for direct retry or redirection can be determined according to the acquired UE multi-band capability information.
