Description
Technical Field
The present invention relates to the field of communications, and in particular, to a communication method, apparatus, and terminal.
Background
In order to maintain the competitiveness of the third Generation mobile communication (3G) System in the communication field, the third Generation Partnership Project (3 GPP) standard working group is working on the evolution Packet domain System (EPS). Fig. 1 is a network architecture diagram of EPS. As shown in fig. 1, the whole EPS mainly includes two parts, namely an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and an Evolved Packet Core (EPC). The EPC can support a user to Access from a Global System for Mobile communications (GSM) Enhanced Data Rate for GSM Evolution (EDGE) Radio Access Network (GERAN, GSM EDGE Radio Access Network) and a Universal Terrestrial Radio Access Network (UTRAN).
The evolved packet core network comprises: a Home subscriber data server (HSS), a Mobility Management Entity (MME), a Serving Gateway (S-GW), a Packet data network Gateway (P-GW, PDN Gateway), a Serving General Packet Radio Service (GPRS) Support Node (SGSN), and a Policy and Charging Rules Function Entity (PCRF).
The HSS is a permanent storage place of the user subscription data and is positioned in a home network subscribed by the user; the MME is a storage place of the user subscription data in the current network and is responsible for Non-Access Stratum (NAS) signaling management from the terminal to the network, tracking and paging management functions and bearer management in an idle mode of the user; the S-GW is a gateway from a core network to a wireless system and is responsible for user plane bearing from a terminal to the core network, data caching in a terminal idle mode, a function of initiating a service request at a network side, and functions of lawful interception, packet data routing and forwarding; the P-GW is an evolved packet domain system and a gateway of an external network of the system, and is responsible for functions of network Protocol (IP, Internet Protocol) address allocation, a charging function, packet filtering, policy application and the like of a terminal; SGSN is a service support point for accessing GERAN and UTRAN users to EPC, and is similar to MME in function and is responsible for functions of user location update, paging management, bearing management and the like; the PCRF is responsible for providing Policy control and Charging rules to a Policy and Charging Enforcement Function entity (PCEF).
Wherein Iu is an interface between a radio network controller and an SGSN, Gr is an interface between the SGSN and an HSS, S1-MME is an interface between a base station and the MME, S1-U is an interface between the base station and an S-GW, S3 is an interface between the MME and the SGSN, S4 is an interface between the SGSN and the S-GW, S5 is an interface between the S-GW and the P-GW, S6a is an interface between the MME and the HSS, S7 is an interface between the P-GW and the PCRF, S10 is an interface between the MME, S11 is an interface between the MME and the S-GW, SCi is an interface between the P-GW and a packet data network, and Rx is a reference point interface between the PCRF and the packet data network.
With the development of intelligent sensors, more and more devices with communication capability, such as non-traditional terminal devices like intelligent cameras and intelligent monitors, can access a network and data communication occurs. The data communication of this type of communication device has the characteristics of small transmission data volume (mainly some data reporting), and infrequent data transmission (timing reporting or bursty data reporting), and this type of terminal is called a mobile Internet of Things (CIoT, Cellular Internet of Things) terminal. In the conventional EPS, because the EPS mainly aims at a terminal which continuously transmits a large amount of data, a complicated conversion between an IDLE state and a connection state is designed, that is, the terminal can transmit data in the connection state and enters the IDLE state (IDLE) without transmitting data. This mechanism ensures high reliability and efficiency of communication. However, when the CIoT terminal accesses the conventional EPS, the CIoT terminal transmits a small amount of data through a complex idle state and connected state conversion process. Thus, signaling waste is caused, and network load is increased.
For the specificity of CIoT terminals, CIoT terminals may access the network architecture as shown in fig. 2. As shown in fig. 2, a mobile internet of things terminal (CIoT UE) is an internet of things terminal that frequently or infrequently transmits small data packets; mobile internet of things radio access network (CIoT RAN) and mobile internet of things packet core network (CIoT EPC) are CIoT's private network, employing simplified or enhanced EPS related functions (mobility management and session management) to support CIoT's data transmission. In order to simplify signaling between interfaces, functions of the MME, the S-GW, and the P-GW in fig. 1 may be integrated into one Network element of a CIoT Core Network (CN), or the MME and the S-GW may be integrated into one Network element and the P-GW is separately provided, so that a roaming scenario may be effectively supported.
In order to support the above functions, the prior art provides a small data transmission flow, as shown in fig. 3:
step 300: the CIoT UE registers to the network and establishes a secure connection with the network;
step 301: the CIoT UE initiates a random access request, wherein the random access request carries a terminal identifier and a connectionless establishment instruction;
step 302: the CIoT RAN returns a random access response, wherein the random access response carries a terminal identifier and uplink authorized resources;
step 303: the CIoT UE sends a random access response, wherein the random access response carries uplink small data, and the small data is transmitted by an encrypted NAS (non-access stratum);
step 304: the CIoT RAN selects a proper core network (such as CIoT EPC) for the CIoT UE according to the terminal identification, and sends an initial UE establishment message, wherein the initial UE establishment message carries the terminal identification and encrypted data;
step 305: CIoT EPC checks the message and decrypts the data; the CIoT EPC sends the small data to the P-GW, and temporarily stores the wireless access network identification of the small data sent by the CIoT UE;
step 306: when downlink small data arrive, the P-GW sends the downlink small data to the CIoT EPC;
step 307: the CIoT EPC performs paging optimization when downlink data arrives according to the stored wireless access network identification, and sends a paging message to the CIoT RAN, wherein the paging message contains encrypted downlink data;
step 308: and the CIoT RAN receiving the paging message pages the CIoT UE, the CIoT UE receives the paging message, sends a response message to the CIoT RAN and acquires encrypted downlink data from the CIoT RAN.
Although most of services of the mobile internet of things are small data services, large data are generated occasionally in consideration of requirements of service upgrading or software upgrading and the like. At this time, if the small data transmission method shown in fig. 3 is still used, the transmission rate is greatly reduced.

In this embodiment, the P-GW detects the data amount and/or transmission frequency of a data packet transmitted to a certain terminal, and determines whether it is suitable to transmit the data packet to the terminal by the small data transmission method as shown in fig. 3. And when the data volume and/or the transmission frequency of the data packet exceed the corresponding threshold, the P-GW triggers and informs the terminal that a common data connection needs to be established or a common network needs to be switched to.

step 503-505: after receiving the specific message or the specific data packet, the CIoT core network sends a paging message, and carries an indication in the paging message to require the terminal to switch to a normal bearer or initiate bearer establishment, or reselect to a normal network to acquire a service (for example, switch to a normal communication indication); the CIoT core network pages the terminal through the CIoT wireless access network, and a paging request of the CIoT wireless access network also carries a corresponding indication;
step 506: the terminal receives the paging message, initiates a Public Data Network (PDN) connection establishment process, or initiates a service request process and establishes a common bearer in the process to acquire data; if the CIoT network does not support this, the terminal reselects to connect to the normal network.

And after the data packet quantity and/or the transmission frequency exceed the corresponding threshold values, the C-GSN caches the data and triggers the notification terminal to establish a common data connection or switch to a common network. As shown in fig. 6, the present embodiment includes the following steps:
step 600: the terminal registers to the network and establishes safe connection with the network;

step 602: the CIoT core network judges whether to inform the terminal to initiate the establishment of the common data connection or switch to the common network according to the data volume and/or the transmission frequency of the received data packet and/or statistical data sent by the P-GW; when the judgment result is that the terminal needs to be notified, the subsequent steps are executed;
if the result is negative, that is, the terminal does not need to be notified, the GIoT core network may notify the P-GW of releasing the response cache, where this operation may be to request the P-GW not to issue the data of the terminal or to release the number of data packets of the terminal within a period of time, and therefore, the notification message may further include time information and/or threshold information of the number of data packets;
step 603-604: the CIoT core network receives the message or the data packet, initiates a paging message, and carries an indication in the paging message to require the terminal to switch to a normal bearer or initiate bearer establishment, or reselect to a normal network to acquire service (for example, switch to a normal communication indication); the CIoT core network pages the terminal through the CIoT wireless access network, and the paging message of the CIoT wireless access network also carries corresponding indication;
step 605: the terminal receives the paging message, initiates a PDN connection establishment process, or initiates a service request process and establishes a common bearer in the process to acquire data; if the CIoT network does not support this, the terminal reselects to connect to the normal network.

step 702: if the P-GW and the CIoT core network establish a control plane tunnel, the P-GW can inform the CIoT core network of needing the terminal to establish common data connection or switching to a common network through a specific message; if the P-GW and the CIoT core network do not establish a control plane tunnel or a bearer, the P-GW may notify the CIoT core network through a specific packet (e.g., a specific packet is generated by a specific packet header or an added tag);
step 703-704: after receiving the specific message or the specific data packet, the CIoT core network sends a paging message to the CIoT radio access network, wherein the paging message includes the specific data packet or an encrypted NAS message, the NAS message may be a detach message or other messages with similar actions, and the message carries an indication to require the terminal to reinitiate a common bearer, or initiate PDN connection establishment, or reselect a common network, thereby acquiring large data transmission;
