Description

Communication method and related device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and a related apparatus.

Background

If the Combined registration of the terminal Equipment (UE) is successful under the third Generation mobile communication technology (3rd-Generation, 3G), for 3G, Circuit Switching (CS) services (such as telephone, short message, supplementary services, etc.) and Packet Switching (PS) services (alternatively referred to as data switching services) are supported concurrently. Therefore, when the upper layer needs to send Data, it may activate a path of Packet Data Protocol (PDP) bearer (for example, bearer ID _ Y, corresponding to the first PS service), and simultaneously activate another path of PDP bearer (for example, bearer ID _ X, corresponding to the second PS service). If there is already one CS service and two PS services, when the first PS service is no longer needed, the network or the higher layer deactivates the Bearer ID _ Y corresponding to the service, and releases the Radio Access Bearer (RAB) corresponding to the Bearer ID _ Y. However, since the synchronization between the core network and the access network may not be successful, if the access network establishes the RAB corresponding to the deactivated bearer ID _ Y, and since the core network deactivates the bearer ID _ Y, the access network may fail to establish the RAB, so that the network may release a Radio Resource Control (RRC) link, thereby causing a CS service failure. Therefore, how to guarantee the sustainability of the CS service under the condition of asynchronous bearer between the RAB of the access network and the core network is an urgent problem to be solved.

In order to facilitate understanding of the embodiments of the present application, some concepts related to the embodiments of the present application are explained below. The description of these concepts includes, but is not limited to, the following.

1. Network device

In this embodiment, the network device may be a device for communicating with the terminal device, and is responsible for Radio Resource Management (RRM), Quality of Service (QoS) Management, data compression and encryption, data transceiving, and the like on the air interface side. The Network device may be a Base Station (BS) in a communication system or a device deployed in a Radio Access Network (RAN) for providing a wireless communication function. For example, a Base Station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) Communication System, a Node B (NB) in a WCDMA Communication System, an evolved Node B (eNB or eNodeB) in an LTE Communication System, a next evolved Node B (ng-eNB) in an NR Communication System, a next evolved Node B (gNB) in an NR Communication System, a Master Node (MN) in a dual link architecture, a second Node or a Secondary Node (SN) in a dual link architecture, and the like, which are not particularly limited.

Optionally, the Network device may also be other devices in a Core Network (CN), such as a Mobile Switching Center (MSC), a Media Gateway (MGW), and the like; the Network may also be an Access Point (AP) in a Wireless Local Area Network (WLAN), a relay station, a communication device in a PLMN Network for future evolution, a communication device in an NTN Network, and the like.

Alternatively, the network device may include means, such as a system-on-chip, for providing wireless communication functions for the terminal device. By way of example, a system of chips may include a chip and may also include other discrete devices.

It should be noted that in some network deployments, the network device may be a stand-alone node to implement all functions of the base station, which may include a Centralized Unit (CU) and a Distributed Unit (DU), such as a gNB-CU and a gNB-DU; an Active Antenna Unit (AAU) may also be included. The CUs may implement part of the functions of the network device, and the DUs may also implement part of the functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services, and implements functions of an RRC layer, a Service Data Adaptation Protocol (SDAP) layer, and a Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for processing a Physical layer protocol and real-time services, and implements functions of a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer. In addition, the AAU may implement portions of physical layer processing functions, radio frequency processing, and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling (e.g., RRC layer signaling) can be considered to be sent by the DU or jointly sent by the DU and the AAU in the network deployment. It is to be understood that the network device may comprise at least one of a CU, a DU, an AAU. In addition, the CU may be divided into Network devices in an Access Network (RAN), or may be divided into Network devices in a core Network, which is not specifically limited.

Alternatively, the network device may have mobile characteristics, for example the network device may be a mobile device. Alternatively, the network device may be a satellite, balloon station. For example, the satellite may be a Low Earth Orbit (LEO) satellite, a Medium Earth Orbit (MEO) satellite, a geosynchronous Orbit (GEO) satellite, a High Elliptic Orbit (HEO) satellite, and the like. Alternatively, the network device may be a base station installed on land, water, or the like.

2. Terminal device

In this embodiment, a terminal device may also be referred to as a terminal, and the terminal may be a User Equipment (UE), a remote/remote terminal (remote UE), a relay device (relay UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote station, a mobile device, a User terminal, an intelligent terminal, a wireless communication device, a User agent, or a User Equipment. It should be noted that the relay device is a terminal capable of providing a relay forwarding service for other terminals (including a remote terminal). In addition, the terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal in a next generation communication system (e.g., NR communication system), a terminal in a future evolved Public Land Mobile Network (PLMN), or the like, and is not particularly limited.

Alternatively, the terminal may be deployed on land, including indoors or outdoors, hand-held, worn, or vehicle-mounted; can be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., an airplane, balloon, or satellite, etc.).

Alternatively, the terminal may be a Mobile Phone (Mobile Phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal device in Industrial Control (Industrial Control), a wireless terminal device in unmanned autonomous driving, a wireless terminal device in Remote Medical treatment (Remote Medical), a wireless terminal device in Smart Grid, a wireless terminal device in Transportation Safety (Transportation Safety), a wireless terminal device in Smart City (Smart City), or a wireless terminal device in Smart Home (Smart Home), and the like.

Further, the terminal may include a device having a transceiving function, such as a system on a chip. The chip system may include a chip and may also include other discrete devices.

3. Activation (activate) and deactivation (deactivate)

The activation refers to that the terminal device or the network device activates a PDP bearer corresponding to a certain PS service, or activates a PDP of a certain path of dedicated bearer. Such as the aforementioned activation of a first bearer for the first PS service and the activation of a second bearer for the second PS service.

Deactivation refers to an operation in which the activated state is terminated by a service provider, user or system. For example, the aforementioned deactivation of the first bearer, i.e. termination of the already activated first bearer. The deactivation mentioned in this application is used to deactivate the bearer corresponding to a certain PS service when the PS service is no longer needed.

4. PDP bearer and RAB

Bearer is understood in colloquial to be a logical path from a core network to a UE. Under the 3G technology, bearers are mainly divided into data bearers and proprietary bearers. The PDP bearer is then the bearer for the packet data protocol. For example, a first PDP bearer for a first PS service, and a second PDP bearer for a second PS service, etc.

RAB is a concept that is used between the UE of the user plane and the core network. When a user initiates a service request, the core network requires the access network to provide the corresponding RAB according to the characteristics of the requested service, regardless of the manner in which the bearer is implemented. This has the advantage of simplifying the interface between the core network and the access network and makes the two network elements more independent, facilitating independent updating of the technologies of each other.

It should be noted that there may be a corresponding relationship between the PDP bearers and the RABs, for example, the first PDP bearer corresponds to the first RAB, and the second PDP bearer corresponds to the second RAB, so as to facilitate service implementation.

In conjunction with the above description, an exemplary illustration of a communication system according to an embodiment of the present application is provided below.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present disclosure. As shown in fig. 1, the communication system includes a terminal device 101 and a network device 102, and the network device 102 includes a core network device 1021 and an access network device 1022. The core network device 1021 may send a first request message to the terminal device 101, where the first request message is used to request to deactivate the first bearer; the terminal device 101 deactivates the first bearer in response to the first request message; when the access network device 1022 requests to establish the first radio resource bearer corresponding to the first bearer, the terminal device 101 sends a first response message to the access network device 1022, where the first response message is used to indicate that the first radio resource bearer corresponding to the first bearer is established. By adopting the method, under the condition that the bearer between the RAB of the access network and the core network is not synchronous, the network equipment actively requests to deactivate a certain bearer, and after the bearer is deactivated, if the network equipment requests to establish the deactivated RAB corresponding to the bearer again, the terminal equipment can send a message that the RAB is successfully established to the network equipment, so that the network equipment can be prevented from releasing an RRC link, and the sustainability of CS service is further ensured.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart illustrating a first communication method according to an embodiment of the present application, and as shown in fig. 2, the communication method may include, but is not limited to, the following steps:

s201, responding to the first request message, and deactivating the first bearer.

The first request message refers to a message sent by the network device to the terminal device to request the deactivation of the first bearer.

The first bearer refers to a logical path connecting the core network and the terminal device, and can be used for the corresponding PS service. For example, the first bearer may be a bearer for opening a web service (first PS service).

In an optional implementation manner, before the terminal device responds to the first request message, the network device sends the first request message to the terminal device, and accordingly, the terminal device receives the first request message, where the first request message is used to request to deactivate the first bearer. It should be noted that the first request message may be a request message sent by the core network device, that is, the core network device requests to deactivate the first bearer.

It should be noted that the network device requesting to deactivate the first bearer refers to: the network device deactivates the first bearer and actively requests the terminal device so that the terminal device also deactivates the first bearer.

In an optional implementation manner, before step S201, the method further includes: when the first packet-switched service and the second packet-switched service are running, a first bearer for the first packet-switched service and a second bearer for the second packet-switched service are activated. Before the first packet switching service and the second packet switching service are operated, the terminal equipment also initiates Combined attachment (Combined attachment) registration to the network equipment; and after the Combined attach registration is successful, operating the CS service.

For example, after the 3G joint add-in device is successfully registered, the terminal device may first run a CS service (e.g., make a call), and then, if it needs to initiate opening a web page (i.e., the first PS service) and playing a video (i.e., the second PS service), the first bearer (e.g., denoted as bearer ID _ Y) for opening the web page and the second bearer (e.g., denoted as bearer ID _ X) for playing the video may be activated. When the service of opening the web page is no longer needed, the network device may send a message requesting to deactivate the bearer ID _ Y to the terminal device, and accordingly, the terminal device receives the request message. Thereafter, the terminal device may deactivate the bearer ID _ Y in response to the request message.

The Combined attach is a CS and PS registration specific procedure initiated by a Wideband Code Division Multiple Access (WCDMA) mobile terminal. In Long Term Evolution (LTE), "Combined" refers to PS service of LTE and CS service of synchronous registration with WCDMA or GSM.

In an optional implementation manner, the terminal device deactivating the first bearer may include the following steps: starting a timer when receiving the first request message; when the timer times out, the first bearer is deactivated.

In an embodiment where the timer is started when the first request message is received, the terminal device may record an RAB corresponding to the first bearer. In this way, when receiving a message sent by the network device to establish an RAB corresponding to another bearer, the RAB corresponding to the other bearer and the RAB corresponding to the first bearer may be compared to determine whether to clear the RAB corresponding to the other bearer. Optionally, the timer may also be started after the access network device establishes the RAB corresponding to the deactivated first bearer. It can be understood that since there is a correspondence between the bearer and the RAB, for example, the correspondence may be a mapping relationship, and therefore, recording the RAB corresponding to the bearer is equivalent to also recording the bearer.

S202, when the network device requests to establish a first radio resource bearer corresponding to the first bearer, sending a first response message to the network device, where the first response message is used to indicate that the first radio resource bearer corresponding to the first bearer is established.

Accordingly, the network device receives the first response message.

It will be appreciated that since the first bearer has been deactivated, the RAB corresponding to the first bearer has also been released, and thus the terminal device is free of RABs corresponding to the first bearer. At this time, when the network device requests to establish the first radio resource bearer corresponding to the deactivated first bearer, the terminal device may send a first response message to the network device. That is to say, under the condition that the bearers between the RAB of the access network device and the core network device are not synchronized, when the access network device requests to establish an RAB corresponding to the deactivated bearer ID _ Y, the terminal device may send, to the access network device, that the RAB corresponding to the bearer ID _ Y is successfully established, instead of that the RAB corresponding to the bearer ID _ Y is failed to be established. Thus, the network device will not release the RRC link, and thus will not cause CS service interruption. It should be noted that the request of the network device for establishing the first radio resource bearer corresponding to the first bearer refers to the request of the access network device for establishing the first radio resource bearer corresponding to the first bearer.

In the embodiment of the application, under the condition that the bearers between the RAB of the access network and the core network are not synchronized, the network equipment actively requests to deactivate a certain bearer, and after the bearer is deactivated, if the network equipment requests to establish the RAB corresponding to the deactivated bearer, the terminal equipment sends a message that the RAB is successfully established to the network equipment, so that the network equipment can be prevented from releasing an RRC link, and the sustainability of a CS service is further ensured.

Referring to fig. 3, fig. 3 is a flowchart illustrating a second communication method according to an embodiment of the present application, and as shown in fig. 3, the communication method may include, but is not limited to, the following steps:

s301, the terminal device sends a second request message to the network device, and correspondingly, the network device receives the second request message, where the second request message is used to request to deactivate the first bearer or request to release the first radio resource bearer corresponding to the first bearer.

The second request message refers to that the terminal equipment requests the network equipment to deactivate the first bearer or requests to release the RAB corresponding to the first bearer.

The description of the first bearer may refer to the description in step S201, and is not repeated herein.

The first radio resource bearer corresponding to the first bearer refers to: the core network device requires the radio bearer provided by the access network device according to the characteristics of the service requested to be operated by the user in the terminal device.

It should be noted that, when the second request message is used to request to deactivate the first bearer, the network device refers to a core network device; when the second request message is used to request to release the first radio resource bearer corresponding to the first bearer, the network device refers to the access network device. When the network device mentioned in the present application activates or deactivates the bearer, the network device refers to a core network device; when the network device establishes or releases the radio resource bearer corresponding to the bearer, the network device refers to an access network device.

In an optional implementation manner, before step S301, the method further includes: when the first packet-switched service and the second packet-switched service are running, a first bearer for the first packet-switched service and a second bearer for the second packet-switched service are activated.

For example, during the process of initiating a call service (i.e., a CS service), the terminal device may simultaneously activate a first bearer (denoted as bearer ID _ Y) for opening a web page (i.e., a first PS service) and a second bearer (denoted as bearer ID _ X) for playing a video (i.e., a second PS service). Optionally, if the service of opening the web page is no longer needed, the terminal device may send a message requesting to deactivate the bearer ID _ Y to the core network device, and correspondingly, the core network device receives the request message.

S302, the network device sends a second response message to the terminal device, and correspondingly, the terminal device receives the second response message, where the second response message is used to instruct the network device to activate the first bearer or establish a first radio resource bearer corresponding to the first bearer.

The second response message refers to a message sent by the network device to the terminal device to activate (i.e., not deactivate) the first bearer, or to establish (i.e., not release) the first RAB corresponding to the first bearer.

And S303, the terminal equipment deactivates the first bearer.

In an optional implementation manner, when the first radio resource bearer corresponding to the first bearer is established, the terminal device may locally deactivate the first bearer. That is, when the terminal device receives the second response message, that is, the network device does not deactivate the first bearer or does not release the first radio resource bearer corresponding to the first bearer, the terminal device may locally deactivate the first bearer.

For example, after the terminal device sends a message requesting to deactivate the bearer ID _ Y or requesting to release the RAB corresponding to the bearer ID _ Y to the network device, if the network device does not deactivate the bearer ID _ Y or does not release the RAB corresponding to the bearer ID _ Y, the terminal device locally deactivates the bearer ID _ Y.

In an optional implementation manner, the terminal device may further start a timer when the receiving network device receives the second request message; when the timer times out, the first bearer is locally deactivated. Optionally, the timer may also be started after the access network device establishes the RAB corresponding to the deactivated first bearer.

In the embodiment of the application, under the condition that the bearers between the RAB of the access network and the core network are not synchronized, the terminal equipment actively requests to deactivate a certain bearer or release the RAB corresponding to the certain bearer, and if the network equipment does not release the RAB corresponding to the bearer after receiving the request, the terminal equipment can locally deactivate the bearer so as to successfully release the RAB corresponding to the bearer, so that the network equipment can be prevented from releasing an RRC link, and the sustainability of CS services is further ensured.

Referring to fig. 4, fig. 4 is a flowchart illustrating a third communication method according to an embodiment of the present application. The flow details the specific implementation flow of the method described in the embodiments of fig. 2 and fig. 3, and further includes a method executed by the terminal device and the network device in the case that the bearer synchronization between the RAB of the access network and the core network is successful. As shown in fig. 4, the communication method includes, but is not limited to, the following steps:

s401, when the first packet switched service and the second packet switched service are operated, activating a first bearer for the first packet switched service and a second bearer for the second packet switched service.

The first packet switched service and the second packet switched service are the aforementioned first PS service and second PS service, and are not described herein again.

Optionally, in an embodiment of activating the first bearer for the first packet switched service and the second bearer for the second packet switched service, the first bearer and the second bearer may be activated by a request sent by the terminal device to the network device, or the first bearer and the second bearer may be activated by a request sent by the network device to the terminal device.

S402, the network device sends a first request message to the terminal device, wherein the first request message is used for requesting to deactivate the first bearer.

Correspondingly, the terminal equipment receives the first request message.

S403, the terminal equipment responds to the first request message and deactivates the first bearer; in case the bearer synchronization between the RAB of the access network and the core network is successful (i.e. the network is normal), performing step S404a-405a or performing step S404b-S405 b; in case the bearer between the RAB of the access network and the core network is not synchronized (i.e. network anomaly), step S404c is performed.

In an alternative embodiment, the specific description of steps S401 to S403 may refer to the related description in step S201, and is not repeated herein.

In an optional implementation manner, the terminal device may include the following steps after deactivating the first bearer: starting a timer; when the timer times out, the first bearer is deactivated.

In an embodiment where the timer is started, the terminal device may record an RAB corresponding to the first bearer. Taking the first bearer as the bearer ID _ Y as an example, the terminal device may mark an RAB corresponding to the bearer ID _ Y as M when receiving the first request message. In this way, when the terminal device receives the message for establishing the other RAB sent by the network device, the other RAB can be compared with the RAB corresponding to the first bearer to determine whether to clear the other RAB. Optionally, the timer may also be started after the access network device establishes the RAB corresponding to the deactivated first bearer.

S404a, the network device sends a first message to the terminal device, where the first message is used to indicate that the first radio resource bearer corresponding to the first bearer is released.

Accordingly, the terminal device receives the first message.

S405a, the terminal device releases the first radio resource bearer corresponding to the first bearer.

In an optional implementation manner, in a case that the network is normal, the network device may release the first radio resource bearer corresponding to the first bearer.

In an optional embodiment, after the network device releases the first radio resource bearer corresponding to the first bearer, the terminal device may clear the RAB corresponding to the recorded bearer ID _ Y and stop the timer.

S404b, the terminal device establishes a third radio resource bearer with the network device in response to the third request message.

Correspondingly, the network device sends a third request message to the terminal device, where the third request message is used to request establishment of a third radio resource bearer.

S405b, if the third rrc bearer is the same as the first rrc bearer, releasing the third rrc bearer.

Optionally, if the third radio resource bearer is different from the first bearer radio resource, it indicates that the third radio resource bearer belongs to the RAB corresponding to the established new bearer.

Taking the first bearer as the bearer ID _ Y as an example, assuming that the terminal device records the RAB corresponding to the bearer ID _ Y as M, when the network device establishes a new RAB (which is recorded as a third radio resource bearer), the terminal device may compare the identifier ID (which is recorded as N) corresponding to the third radio resource bearer with the recorded M. If the first radio resource bearer is the same (i.e., M ═ N), clearing the third radio resource bearer (i.e., releasing the third radio resource bearer); if the difference is not equal to N, it indicates that the third radio resource bearer belongs to the RAB corresponding to the established new bearer.

S404c, when the network device requests to establish a first radio resource bearer corresponding to the first bearer, sending a first response message to the network device, where the first response message is used to indicate that the first radio resource bearer corresponding to the first bearer is established.

In an alternative embodiment, the detailed description of step S404c may refer to the description in step S202, and is not repeated here.

In the embodiment of the application, regardless of whether the network is normal or not, the RAB corresponding to the deactivated bearer can be successfully established or normally released, so that the network equipment does not release the RRC link, and the terminal equipment can perform a normal CS service.

Referring to fig. 5, fig. 5 is a schematic diagram of a fourth communication method provided in the embodiment of the present application, where the communication method corresponds to the third communication method shown in fig. 4. The difference is that the method not only describes the steps executed by the network device specifically as the steps executed by the access network device and the steps executed by the core network device, but also describes the interaction between the core network device and/or the access network device and the internal module of the terminal device. AS shown in fig. 5, the terminal device mainly includes three modules, a Non-Access-Stratum (NAS) module, a higher layer (for example, referred to AS an AP) module, and a Radio Resource Control (referred to AS a W-Radio Resource Control (WRRC) module (or referred to AS an Access-Stratum (AS) module) under 3G. The WRRC module belongs to a module interactive with an access network, and maintains a cache for recording RAB established by the network; the NAS module belongs to a module interacted with a core network and is mainly used for interacting bearing related information; the AP belongs to a module interacting with a User Interface (UI), and only if a certain path of bearer activation or deactivation is successful, the next activation or deactivation process can be performed. As shown in fig. 5, the communication method may include, but is not limited to, the following steps:

501. the terminal equipment initiates the successful COMBINED ATTACH registration to the access network equipment through the WRRC module, and initiates a CS service.

502. The terminal device receives, through the NAS module, a request from the core network device to activate the PDP bearer ID _ Y for the first PS service and the PDP bearer ID _ X for the second PS service, which may be, for example, an PDP ACTIVATE REQ message including a request to activate the bearer ID _ Y and/or the bearer ID _ X.

503. The NAS module sends a message to the core network device that bearer ID _ X and bearer ID _ Y are activated in response to the request in 502, for example, the message may be PDP ACTIVATE ACCEPT message including bearer ID _ Y and/or bearer ID _ X being activated.

It is understood that 502 may correspond to S401 of fig. 4, supra.

504. The NAS module replies to the higher layer with a message that the activation of PDP bearer ID _ X and PDP bearer ID _ Y was successful, which may be, for example, an ACT PDP SUCCESS message including bearer ID _ Y and/or bearer ID _ X activation SUCCESS.

505. The access network equipment sends a message for establishing a bearer ID _ X and an RAB corresponding to the bearer ID _ Y to a WRRC module; accordingly, the WRRC module receives the message. For example, the message may be a radio bearer setup message including the RAB corresponding to the setup bearer ID _ Y and/or the RAB corresponding to the bearer ID _ X.

506. The WRRC module sends a RAB setup complete message to the access network device, for example, the message may be a rababerrersetupcomple message, including a RAB corresponding to bearer ID _ Y and/or a RAB setup complete corresponding to bearer ID _ X.

507. When the first PS service corresponding to the bearer ID _ Y is no longer needed, a request for deactivating the bearer ID _ Y is sent to the NAS module through the higher layer, for example, the message may be an DEACT PDP REQ message, which includes a request for deactivating the bearer ID _ Y.

508. After receiving the request for deactivating the bearer ID _ Y, the NAS module sends the request to the core network device. For example, the message may be an PDP DEACTIVATE REQ message including a request to deactivate bearer ID _ Y.

509. The NAS module receives a message from the core network device that the deactivation of the bearer ID _ Y is successful, which may be, for example, an PDP DEACTIVATE ACCEPT message including that the bearer ID _ Y is deactivated.

It is understood that 508-509 may correspond to the aforementioned step S201.

510. And recording the RAB corresponding to the deactivated bearer ID _ Y as M through the NAS module, and simultaneously starting a timer. At this time, the following four cases can be divided:

in case one, if the network is in a normal condition, the WRRC module receives a message from the access network device for releasing the RAB corresponding to the BEARER ID _ Y, for example, the message may be a RADIO BEARER RELEASE message including the RAB corresponding to the BEARER ID _ Y (corresponding to 511a in fig. 5). And then, the WRRC module sends a message of completing RAB release corresponding to the bearer ID _ Y to the access network equipment. For example, the message may be a RADIO BEARER RELEASE COMPLETE message including the RAB RELEASE COMPLETE corresponding to the BEARER ID _ Y (corresponding to 512a in fig. 5). Then, the WRRC module sends a message that the RAB corresponding to the bearer ID _ Y is released to the NAS module. This message may be, for example, a RAB _ REL _ IND message including that the RAB corresponding to the bearer ID _ Y is released (corresponding to 513a in fig. 5). After receiving the message that the RAB corresponding to the bearer ID _ Y is released, the NAS module compares the identity ID carried in the message with the previously recorded M (corresponding to 514a in fig. 5). If so, the higher layer is replied to successfully deactivate the bearer, and the timer is stopped, for example, the message replied to the higher layer may be a deactivate PDP SUCCESS message, including the SUCCESS of deactivating the bearer ID _ Y (corresponding to 515 in fig. 5).

It is understood that the process of the core network device and/or the access network device interacting with the terminal device internal module described in case one may correspond to the aforementioned steps S404a-S405 a.

In case of the second scenario, if the WRRC module receives a message from the access network device to establish another new RAB (e.g., RAB corresponding to bearer ID _ Z). For example, the message may be a RADIO BEARER SETUP message including the RAB (corresponding to 511b in fig. 5) corresponding to the SETUP BEARER ID _ Z. After that, the WRRC module sends a message that RAB establishment is completed corresponding to the BEARER ID _ Z to the access network device, for example, the message may be a RADIO BEARER SETUP COMPLETE message, which includes RAB establishment corresponding to the BEARER ID _ Z (corresponding to 512b in fig. 5). Then, the WRRC module sends a message that RAB corresponding to the bearer ID _ Z is established to the NAS. For example, the message may be a RAB _ EST _ IND message including that a RAB corresponding to the bearer ID _ Z is established (corresponding to 513b in fig. 5). After receiving the message, the NAS module first compares ID _ Z with the recorded M (corresponding to 514b in fig. 5), and if not equal, it indicates that the RAB corresponding to bearer ID _ Z belongs to the new RAB. If the two are equal, the network is abnormal, and the situation described in the third situation is entered.

It is understood that the process of the core network device and/or the access network device interacting with the terminal device internal module described in case two may correspond to the aforementioned steps S404b-S405 b.

In case of an abnormal network, when the access network device establishes the RAB corresponding to the deactivated BEARER ID _ Y again, for example, when the access network device sends a RADIO BEARER SETUP message to the terminal device, where the RAB corresponding to the BEARER ID _ Y is established (corresponding to 511c in fig. 5), since the BEARER ID _ Y is deactivated at this time, the NAS module of the terminal device does not have the first BEARER. However, since the WRRC module maintains a buffer by itself, and records the RAB established by the access network device, the RAB recorded in the module is not cleared. Therefore, the WRRC module replies to the access network device that RAB establishment is successful, for example, replies to the RADIO BEARER SETUP COMPLETE message including RAB establishment corresponding to the BEARER ID _ Y (corresponding to 512c in fig. 5). After that, the WRRC module sends a message to the NAS module that the RAB corresponding to the bearer ID _ Y is established, for example, the message may be a RAB _ EST _ IND message, which includes that the RAB corresponding to the bearer ID _ Y is established (corresponding to 513c in fig. 5). After receiving the message, the NAS module first compares ID _ Y with the recorded M (corresponding to 514c in fig. 5), and if they are equal, the NAS module sends a message to CLEAR the RAB to the WRRC module, for example, the message may be a RAB _ CLEAR _ IND message including a RAB (corresponding to 515c in fig. 5) corresponding to the CLEAR bearer ID _ Y, so as to request the WRRC module to CLEAR the RAB corresponding to the bearer ID _ Z. While replying to the higher layer for SUCCESS in deactivating the bearer and stopping the timer, for example, the message replied to the higher layer may be a deactivate PDP SUCCESS message including SUCCESS in deactivating the bearer ID _ Y (corresponding to 515 in fig. 5). It can be understood that, the case where the newly created RAB in the second case is equal to the recorded RAB is connected, that is, the case where the access network device establishes the RAB corresponding to the deactivated bearer ID _ Y again.

It is understood that the process of the core network device and/or the access network device interacting with the terminal device internal module described in case three may correspond to the aforementioned step S404 c.

In case four, if the NAS module receives a message of deactivating the bearer ID _ Y of the core network device, for example, after receiving the PDP DEACTIVATE ACCEPT message (corresponding to 509 in fig. 5), the access network device does not release the RAB corresponding to the bearer or does not release the RRC link, and the timer may time out. When the timer expires, the terminal device locally deactivates the bearer ID _ Y through the NAS module (corresponding to 511d in fig. 5). The NAS module then sends a message to the WRRC module to CLEAR the RAB again, for example, the message may be a RAB _ CLEAR _ IND message including the RAB corresponding to the CLEAR bearer ID _ Y (corresponding to 515d in fig. 5), to request the WRRC module to CLEAR the RAB corresponding to the bearer ID _ Y and reply to the higher layer that the deactivation of the bearer ID _ Y is successful (corresponding to 515 in fig. 5).

It is understood that the process of the core network device and/or the access network device interacting with the terminal device internal module described in case four may correspond to the foregoing step S303.

In the embodiment of the application, no matter whether the network is normal (namely, the condition of network abnormity is compatible) or not, the terminal equipment cannot send the RAB establishment failure message to the network equipment through the interaction between the terminal equipment internal module and the network equipment, so that the network equipment is prevented from releasing an RRC link, and the terminal equipment can perform normal CS service.

It should be noted that the methods shown in fig. 2 to fig. 5 can be applied not only to a scenario in which a CS service and a PS service coexist in the 3G technology, but also to a scenario in which only a plurality of PS services exist. When the method is applied to a scene where only a plurality of PS services exist, regardless of whether the network is normal or not, the RAB corresponding to a certain path of bearers (for example, a second bearer corresponding to a second PS service) that has been deactivated can be successfully established or normally released, so that the network device does not release the RRC link, and normal operation of other PS services can be ensured.
