[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202311174272.9 filed in China on September 12, 2023, the entire contents of which are incorporated herein by reference. The applicant also claims priority to Chinese Patent Application No. 202410603617.6 filed in China on May 15, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a communication processing, information transmission method, device and communication equipment. Background Art

[0004] There are two options for interworking between the Evolved Packet System (EPS) and the 5G Core Network (5GC) in related technologies: supporting the N26 interface and not supporting it. Without N26, the standard already supports dual registration, allowing user equipment (UE) to establish separate sessions on 4G and 5G to transmit data. With N26, the standard only supports single registration, preventing UEs from establishing separate sessions on 4G and 5G.

[0005] The N26 interface is an interface between the 5G (New Radio, NR) core network Access and Mobility Management Function (AMF) and the 4G (Long Term Evolution, LTE) core network Mobility Management Entity (MME). It enables information exchange between the 5GC and the Evolved Packet Core (EPC). Support for the N26 interface in both 4G and 5G networks is optional for mobile network operators.

[0006] Optionally, in the case of the subsequent introduction of a new network system with access network technology different from 5G and 4G, a corresponding communication interface may also exist between the network function in the new network system that can realize the mobility management function and the AMF of 5G and the MME of 4G.

[0007] Currently, interfaces between network functions capable of implementing mobility management functions on different access network technologies only support single registration, preventing terminals from establishing separate sessions on networks with different access network technologies. For terminals that support dual or even multi-registration, one implementation approach is to register with a second network to assist with data transmission when the terminal detects poor signal quality or service quality on one network. However, this approach results in frequent registration processes and increases network registration latency.

[0286] The communication processing, information transmission method, apparatus and communication equipment provided by the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0287] As shown in FIG2 , an embodiment of the present application provides a communication processing method, including:

[0288] Step 201: When a terminal is registered with at least two networks and is in a radio resource control (RRC) connected state in a first network and in an RRC idle state or an RRC inactive state in a second network, if a first condition is met, an RRC connection establishment process or an RRC connection recovery process is triggered to a second access network device corresponding to the second network.

[0289] It should be noted that the terminal referred to in the embodiment of the present application can be a terminal that can register and access two networks, that is, the terminal supports dual registration (that is, the terminal is in dual registration mode), and such a terminal can also be called a dual registration terminal; it can also be a terminal that can register and access more than two networks, that is, the terminal supports multi-registration (that is, the terminal is in multi-registration mode), and such a terminal can also be called a multi-registration terminal.

[0290] Optionally, the multiple (two or more) networks accessed by the terminal belong to the same or different access network technologies respectively; for example, the access network technology may include but is not limited to at least one of the following: 4G, 5G, 6G.

[0291] For example, taking the terminal supporting dual registration as an example, one network registered by the terminal may be 5G, and the other network registered by the terminal may be 4G. Specifically, the UE registers with the Evolved Packet Core (EPC) in the 4G system and the 5GC in the 5G system. When the UE is registered on both sides, the UE can establish an RRC connection with the LTE base station of the 4G system and the NR base station of the 5G system. Taking the terminal supporting multiple registrations as an example, the first network registered by the terminal may be 5G, the second network registered by the terminal may be 4G, and the third network registered by the terminal may be 6G. Optionally, the terminal usually uses a network with a high access network technology for data transmission, while the network with a low access network technology is in an RRC idle state or an RRC inactive state. That is, in this case, the access network technology version of the first network in the embodiment of the present application is higher than the access network technology version of the second network. For example, taking the terminal supporting dual registration as an example, the first network is a 5G network and the second network is a 4G network. Optionally, the two networks registered by the terminal may also be the same access network technology. For example, one network registered by the terminal may be 5G, and the other network registered by the terminal may also be 5G.

[0292] It should also be noted that when the terminal supports multiple registrations, the second network can be one or more networks that have been multi-registered for access. For example, the terminal has registered and accessed the 5G network, 4G network and 6G network respectively. The terminal currently transmits the target service through the 6G network. When the first condition is met, the terminal can trigger the access network device under the 5G network to initiate RRC connection establishment, and it can also trigger the access network device under the 4G network to initiate RRC connection establishment, or it can simultaneously trigger the access network devices under the 5G network and the 4G network to initiate RRC connection establishment respectively.

[0293] Optionally, in one implementation, the first condition includes at least one of the following:

[0294] A11. The signal quality of the terminal in the cell in the first network is lower than or equal to a first measurement threshold;

[0295] Signal quality lower than or equal to the first measurement threshold can be understood as poor transmission quality. This situation can be understood as the terminal's transmission quality in the current network is poor and other networks need to be used to assist in transmission in a timely manner.

[0296] A12. The service rate of the terminal in the cell of the first network is lower than or equal to the first service rate threshold;

[0297] A service rate lower than or equal to the first service rate threshold can be understood as a low transmission rate. This situation can be understood as the terminal having a low transmission rate in the current network and requiring timely use of other networks to assist in transmission.

[0298] A13. The service rate to be sent by the terminal in the first network is higher than or equal to the second service rate threshold;

[0299] The pending service rate being higher than or equal to the second service rate threshold can be understood as a higher transmission rate, that is, a larger amount of data to be transmitted. This situation can be understood as a larger amount of data to be transmitted by the terminal in the current network, and other networks need to be used to assist in transmission in a timely manner.

[0300] A14. The service characteristics of the pending service require multi-RRC transmission to be enabled;

[0301] In this case, whether to enable multiple RRC transmissions can be determined directly based on the service characteristics. The multiple RRC transmissions include two RRC transmissions (i.e., dual RRC transmissions) and / or more than two RRC transmissions. For example, if the service characteristics indicate that dual RRC transmissions need to be enabled, it is necessary to trigger the access network device of another network to initiate the RRC connection establishment process.

[0302] A15. The signal quality of the terminal in the cell in the second network is higher than or equal to the second measurement threshold;

[0303] The signal quality being higher than or equal to the second measurement threshold can be understood as the transmission quality of the second network being better. This situation can be understood as the transmission quality of the terminal under the first network being poor, and the second network needs to be used to assist in transmission in a timely manner, and the signal quality of the second network is better.

[0304] A16. The service rate of the terminal in the cell in the second network is higher than or equal to a third service rate threshold;

[0305] A service rate higher than or equal to the third service rate threshold can be understood as the second network service transmission rate is better. This situation can be understood as the terminal's transmission rate under the first network is low, and the second network needs to be used to assist in transmission in a timely manner, and the second network service rate is better.

[0306] It should be noted here that, when the second network is in the RRC idle state, if the first condition is met, the RRC connection establishment process is triggered to the second access network device corresponding to the second network; when the second network is in the RRC inactive state, if the first condition is met, the RRC connection recovery process is triggered to the second access network device corresponding to the second network.

[0307] Optionally, in one implementation, if the first condition is met, triggering the initiation of an RRC connection establishment process to the second access network device corresponding to the second network includes:

[0308] When the first condition is met, the terminal sends an RRC connection establishment request message or an RRC connection recovery request message to a second access network device corresponding to the second network;

[0309] Among them, the RRC connection establishment request reason or RRC recovery reason carried in the RRC connection establishment request message or the RRC connection recovery request message includes: the link coverage of the first network is poor, and a request is made to establish an RRC connection under the second network; or, the terminal has business data to be transmitted and an RRC connection under the second network needs to be established.

[0310] Optionally, the RRC connection establishment request message carries an RRC connection establishment request cause; and the RRC connection recovery request message carries an RRC recovery cause (the RRC recovery cause may also be referred to as an RRC connection recovery cause).

[0311] In a specific implementation, the RRC layer of the terminal first determines whether the first condition is met. If the RRC layer determines that the first condition is met, it triggers an indication to the non-access stratum (NAS) layer of the terminal, thereby causing the NAS to trigger a service request. It should be noted that because the service request can only be executed when the terminal is in an RRC connected state, the terminal needs to be connected to the second access network device corresponding to the second network. Optionally, the implementation process specifically includes:

[0312] The RRC layer of the terminal sends an RRC connection establishment request message or an RRC connection recovery request message to the second access network device under the second network, and the RRC layer of the terminal receives the RRC connection establishment message or the RRC connection recovery request message sent by the second access network device; after the RRC of the terminal receives the RRC connection establishment message or the RRC connection recovery message, the RRC layer of the terminal will send an RRC connection establishment completion message or an RRC connection recovery completion message to the second access network device, and the terminal can connect to the second access network device, wherein the service request message of the NAS layer of the terminal can be included in the RRC connection establishment completion message or the RRC connection recovery completion message. After the second core network device receives the service request message, it can execute the service request process to realize the transmission of the target service of the terminal.

[0313] It should be noted that the RRC connection establishment process corresponds to the RRC connection establishment request message, RRC connection establishment message and RRC connection completion message; the RRC connection recovery process corresponds to the RRC connection recovery request message, RRC connection recovery message and RRC connection recovery completion message.

[0314] It should be noted that the above is aimed at how the terminal uses multiple RRC connections to transmit information when it is in dual registration mode or multi-registration mode; the following describes in detail how the terminal enters dual registration mode or multi-registration mode.

[0315] Optionally, in one implementation, the method further includes:

[0316] The terminal receives first configuration information before registering to access at least two networks and when registering to access a third network;

[0317] It should be noted that the third network can be understood as the network that the terminal accesses in single registration mode. Optionally, after the terminal is in dual registration mode or multi-registration mode, the third network is any one of the at least two networks that the terminal registers to access.

[0318] Optionally, the first configuration information includes at least one of the following:

[0319] B11. Third indication information, where the third indication information is used to indicate that the terminal is allowed to register and access at least two networks;

[0320] B12, first measurement threshold;

[0321] B13, first service rate threshold;

[0322] B14, second service rate threshold;

[0323] B15, second measurement threshold;

[0324] B16, the third service rate threshold.

[0325] Optionally, as long as the terminal receives any one or more of the information in B11-B16 above, the terminal is allowed to register and access a new network, and can enter the dual registration mode or the multi-registration mode.

[0326] It should be noted that when the terminal registers to access a new network, it needs to trigger the RRC connection establishment process. Specifically, the establishment cause carried in the RRC connection establishment request message during the RRC connection establishment process may be dual registration or multiple registration, or the establishment cause carried may be a cause value related to dual registration or multiple registration.

[0327] Optionally, in one implementation, the receiving the first configuration information includes one of the following:

[0328] C11. The terminal receives first configuration information sent by the third core network device under the third network through a NAS message;

[0329] This situation can be understood as that the first configuration information is configured by the core network device. After configuring the first configuration information, the core network device needs to send the first configuration information to the terminal through a NAS message.

[0330] It should be noted that, since it is the RRC layer of the terminal that ultimately uses the first configuration information, the NAS layer of the terminal needs to forward the first configuration information to the RRC layer of the terminal after receiving the first configuration information.

[0331] C12. The terminal receives first configuration information sent by the third access network device under the third network through an RRC message;

[0332] This situation can be understood as the first configuration information is configured by the access network device. After configuring the first configuration information, the access network device needs to send the first configuration information to the terminal through an RRC message, and the RRC layer of the terminal finally receives the first configuration information.

[0333] Optionally, another implementation method may be that after the terminal initiates registration with the second network, the second core network device under the second network notifies the first core network device under the first network (the network to which the terminal is connected in single registration mode) that dual registration is completed, and the first core network device sends the first configuration information to the NAS layer of the terminal through a NAS message, and the NAS layer of the terminal forwards the first configuration information to the RRC layer of the terminal; or, the first core network instructs the first access network device under the first network to complete dual registration, and the first access network device sends the first configuration information to the RRC layer of the UE through an RRC message.

[0334] It should be noted that, after the first access device or the first core network receives the dual registration completion information indicated by the second core network, it can configure the first configuration information for the terminal.

[0335] Optionally, before receiving the first configuration information, the method further includes:

[0336] Send fourth indication information to a third core network device or a third access network device under the third network, where the fourth indication information is used to indicate that the terminal supports registration access to at least two networks.

[0337] It should be noted that after the third core network device or the third access network device receives the fourth indication information, it can configure the first configuration information for the terminal.

[0338] Optionally, when the terminal sends the fourth indication information to the third core network device, the first configuration information is sent by the third core network device to the terminal; optionally, when the terminal sends the fourth indication information to the third access network device, the first configuration information is sent by the third access network device to the terminal.

[0339] It should be noted that the terminal can determine when to initiate an RRC connection to the second network through the trigger conditions configured in the first configuration information, so that when there is no connection requirement, the second network can be suspended while maintaining the registration state, thereby preventing frequent triggering of the registration process and reducing the registration delay.

[0340] It should be noted that when the terminal is in dual registration mode or multi-registration mode, it is necessary to avoid inter-radio access technology (inter-RAT) switching. Optionally, in order to solve this problem in the embodiment of the present application, one of the following implementation methods can be adopted:

[0341] Implementation method 1:

[0342] The terminal receives, respectively, second configuration information sent by an access network device in each of the at least two networks with which the terminal has an RRC connection, where the second configuration information does not include inter-RAT measurement configuration information;

[0343] It should be noted that by sending measurement configuration information that does not include inter-RAT to the terminal, the terminal will know that when performing cell measurement under the current network, it will not measure cells with a different RAT from the current serving cell. Therefore, when reporting measurements to the access network device, the measurement results of cells with a different RAT from the current serving cell will not be reported. As a result, the access network device will not select a cross-RAT cell when selecting a switching cell, thereby ensuring that inter-RAT switching will not be triggered.

[0344] Optionally, in this case, if the terminal completes registration under the second network, the second core network device needs to send a fifth indication message to the first core network device; after the first core network device receives the fifth indication message sent by the second core network device, it needs to send a sixth indication message to the first access network device. The sixth indication message is used to instruct the terminal to complete registration and access at least two networks, and then the first access network device and the second access network device respectively send the second configuration information to the terminal.

[0345] The fifth indication information includes at least one of the following:

[0346] D11, identification information of the terminal;

[0347] For example, the identification information may be a 5G Globally Unique Temporary UE Identity (5G-GUTI).

[0348] D12: An indication that the terminal has completed registration with the second network.

[0349] Implementation method 2:

[0350] After establishing an RRC connection with the second network, the terminal reports first indication information to a second access network device under the second network, where the first indication information is used to indicate that a switching capability between temporary radio access technologies is not supported.

[0351] It should be noted that the not supporting temporary handover capability between radio access technologies can be understood as not being able to configure measurement configuration of cells between radio access technologies in the current case of multiple RRC connections.

[0352] It should also be noted here that after the terminal establishes an RRC connection with the first network, it also needs to report first indication information to the first access network device under the first network, where the first indication information is used to indicate that the switching capability between temporary wireless access technologies is not supported.

[0353] That is to say, in the case of multiple RRC connections, the terminal needs to send the first indication information to the access network device corresponding to each network, and the terminal cannot perform inter-RAT switching in each network.

[0354] After the access network device receives the first indication information sent by the terminal, the access network device determines that inter-RAT cell handover of the terminal is not possible. Optionally, in one case, the terminal does not configure inter-RAT measurement parameters (i.e., measurement configuration information) when configuring cell measurement parameters. The terminal then knows that when performing cell measurement in the current network, it will not measure cells that do not belong to the same RAT or cells that are of a different RAT from the current serving cell. Therefore, when reporting measurements to the access network device, the terminal does not report measurement results of cells of a different RAT from the current serving cell. Consequently, the access network device will not select an inter-RAT cell when selecting a handover cell, thereby ensuring that inter-RAT handover is not triggered. Optionally, in another case, when knowing that inter-RAT cell handover is not possible, the access network device may configure measurement parameters normally, that is, may configure inter-RAT measurement configuration information to the terminal. The terminal may perform measurement reporting according to the measurement parameters configured by the access network device. However, when selecting a handover cell, the access network device will not select an inter-RAT cell, thereby ensuring that the terminal does not switch to an inter-RAT cell.

[0355] Optionally, in this case, in one implementation, the method further includes:

[0356] When the second network becomes the only registered network of the terminal, or is the only network with which an RRC connection is established among the at least two registered networks, the terminal sends a second indication message to the second access network device corresponding to the second network; the second indication message is used to indicate that the handover capability between radio access technologies is restored.

[0357] That is, when the terminal exits the multi-registration mode, it needs to send a second indication message to the currently connected access network device to inform the access network device that the inter-radio access technology switching capability is restored, that is, it can configure inter-RAT switching when performing cell switching.

[0358] Among them, the second network is not limited to the network to which the terminal later initiates RRC connection establishment or connection recovery or later initiates registration. The second network can also be the network during the initial single registration, that is, the second network can be the network to which any terminal connects after resuming single registration.

[0359] Implementation method three:

[0360] After establishing an RRC connection with the second network, the terminal reports first terminal capability update information to a second access network device under the second network, where the first terminal capability update is used to update the handover capability of the terminal between radio access technologies.

[0361] It should be noted that, it can be understood here that after the terminal establishes an RRC connection with the second network, it needs to initiate a first terminal capability update process, and when initiating the first terminal capability update process, the terminal needs to send the first terminal capability update information to the second access network device.

[0362] It should be noted here that when the terminal capability stored on the second access network device side is the terminal's support for switching between wireless access technologies, after receiving the first terminal capability update information, the terminal capability needs to be updated to the terminal's non-support for switching between wireless access technologies.

[0363] It should also be noted here that after the terminal establishes an RRC connection with the first network, it also needs to initiate a first terminal capability update process to the first access network device under the first network, that is, the terminal sends the first terminal capability update information to the first access network device.

[0364] That is to say, in the case of multiple RRC connections, the terminal needs to send the first terminal capability update information to the access network device corresponding to each network, and the terminal cannot perform inter-RAT switching in each network.

[0365] After the access network device receives the first terminal capability update information sent by the terminal, the access network device determines that inter-RAT cell handover of the terminal is not possible. Optionally, in one case, the terminal does not configure inter-RAT measurement parameters (i.e., measurement configuration information) when configuring cell measurement parameters. The terminal then knows not to measure cells that do not belong to the same RAT or do not measure cells with a different RAT from the current serving cell when performing cell measurement in the current network. Therefore, when reporting measurements to the access network device, the terminal does not report measurement results of cells with a different RAT from the current serving cell. Consequently, when selecting a handover cell, the access network device does not select an inter-RAT cell, thereby ensuring that inter-RAT handover is not triggered. Optionally, in another case, when knowing that inter-RAT cell handover is not possible, the access network device may configure measurement parameters normally, i.e., configure inter-RAT measurement configuration information to the terminal. The terminal may perform measurement reporting according to the measurement parameters configured by the access network device. However, when selecting a handover cell, the base station does not select an inter-RAT cell, thereby ensuring that the terminal does not switch to an inter-RAT cell.

[0366] Optionally, in this case, in one implementation, the method further includes:

[0367] When the second network becomes the only registered network of the terminal, or is the only network with which an RRC connection is established among the at least two registered networks, the terminal sends second terminal capability update information to the second access network device corresponding to the second network; the second terminal capability update information is used to update the terminal's switching capability between wireless access technologies.

[0368] It should be noted that, it can be understood here that when the second network becomes the only registered network of the terminal, or is the only network to establish an RRC connection among the at least two registered networks, the terminal needs to initiate a second terminal capability update process, and when initiating the second terminal capability update process, the terminal needs to send the second terminal capability update information to the second access network device.

[0369] It should be noted here that when the terminal capability stored on the second access network device side is that the terminal does not support switching capabilities between wireless access technologies, after receiving the second terminal capability update information, the terminal capability needs to be updated to support switching capabilities between wireless access technologies.

[0370] Among them, the second network is not limited to the network to which the terminal later initiates RRC connection establishment or connection recovery or later initiates registration. The second network can also be the network during the initial single registration, that is, the second network can be the network to which any terminal connects after resuming single registration.

[0371] That is to say, when the terminal exits the multi-registration mode, it needs to send the second terminal capability update information to the currently connected access network device to inform the access network device that the terminal can switch between wireless access technologies, that is, it can configure cross-RAT switching when performing cell switching.

[0372] The following takes the terminal performing dual registration as an example to illustrate the specific application of the embodiment of the present application.

[0373] Application scenario 1: Terminal activation of dual RRC connection establishment

[0374] Step S11: The current terminal is in single registration mode and accesses the first network. The terminal reports to the currently accessed network that it supports dual registration; for example, the first network accessed by the terminal is a 5GC and NR base station.

[0375] Optionally, the terminal may report fourth indication information to the core network or report fourth indication information to the base station, where the fourth indication information is used to indicate that the terminal supports registration and access to two networks.

[0376] Step S12: The terminal receives first configuration information, where the first configuration information includes at least one of the following:

[0377] First indication information, the first indication information is used to indicate that the terminal is allowed to register and access two networks, that is, the terminal can perform dual registration;

[0378] First measurement threshold;

[0379] A first service rate threshold;

[0380] Second service rate threshold.

[0381] The first configuration information may be sent by the core network of the first network through a NAS message; optionally, the first configuration information may also be configured by the base station of the first network through an RRC message.

[0382] Step S13: If the terminal receives the first configuration information through a NAS message, the NAS layer of the terminal forwards the first configuration information to the RRC layer of the terminal;

[0383] Step S14: The terminal performs a second network registration (for example, accessing an EPC and an LTE base station). During the registration process, when initiating an RRC connection establishment, the establishment cause may be a dual registration or other cause value related to dual registration.

[0384] Step S15: The terminal is in dual registration mode (one network access is NR and the other network access is LTE). The NR signal quality is always good, and the service is transmitted on the NR network. The other LTE network enters the RRC_IDLE state (or CM_IDLE state on the core network side) or RRC_INACTIVE state (or CM_CONNECTED state on the core network side) due to no data transmission for a long time. At this time, it can be considered that the terminal is still registered in the LTE core network.

[0385] Step S16: When the first condition is met, the RRC layer of the terminal indicates to the NAS, so that the NAS triggers the service request; specifically, the following steps are included:

[0386] Step S16a, the RRC layer of the terminal initiates an RRC connection establishment request message to the base station, wherein the RRC connection establishment request message carries the RRC connection establishment request reason of poor NR link coverage, requesting to establish a second RRC connection, or the terminal has service data to be transmitted and needs to establish an RRC connection under the LTE network, or the RRC connection establishment request may also be other reasons related to MO;

[0387] Step S16b: The RRC layer of the terminal receives the RRC connection establishment message sent by the base station;

[0388] Step S16c: The NAS layer of the terminal sends a service request message to the core network (MME) of the LTE network. The service request message is included in the RRC connection establishment complete message.

[0389] Step S16d: Execute the subsequent service request process.

[0390] The first condition includes at least one of the following:

[0391] The signal quality of the cell in the NR network is lower than or equal to the first measurement threshold;

[0392] A service rate in the cell in the NR network is lower than or equal to the first service rate;

[0393] The service rate to be sent in the NR network is higher than or equal to the second service rate;

[0394] The service characteristics of the pending service require dual RRC transmission to be enabled.

[0395] Application scenario 2: After the terminal activates dual RRC connections, network configuration is used to prevent inter-RAT switching

[0396] Steps S21 to S23 are the same as steps S11 to S13 in application scenario 1;

[0397] Step S24: The terminal completes registration with the second network. An N26 interface is established between the two core networks (AMF and MME).

[0398] Step S25: The terminal receives UECapabilityEnquiry signaling from the two networks respectively;

[0399] Step S26: The terminal reports its capabilities to the two networks through UECapabilityInformation, including inter-RAT handover capabilities.

[0400] Step S27: The terminal receives second configuration information of the two networks respectively, where the second configuration information does not include inter-RAT measurement configuration information;

[0401] Furthermore, after the terminal completes the second network registration, the main implementation process on the network side includes:

[0402] Step S201: The AMF receives fifth indication information, where the fifth indication information is sent by the MME to the AMF, and the indication information includes at least one of the following:

[0403] Identification information of the terminal, such as 5G-GUTI, etc.;

[0404] The terminal has completed the second network registration indication.

[0405] Step S202: The AMF indicates to the NR base station that the terminal has completed dual registration.

[0406] In step S203, the NR base station and the LTE base station respectively send second configuration information to the terminal, where the second configuration information does not include inter-RAT measurement configuration information.

[0407] Application scenario 3: After the terminal activates the dual RRC connection, the terminal indicates information to prevent inter-RAT switching

[0408] Steps S31 to S33 are the same as steps S11 to S13 in application scenario 1;

[0409] Step S34: The terminal enters the dual registration mode and is in the RRC connected state in both networks. The terminal receives UECapabilityEnquiry signaling from the two networks respectively.

[0410] Step S35: The terminal reports its capabilities to the two networks respectively through UECapabilityInformation, including inter-RAT handover capability.

[0411] Step S36: The terminal reports first indication information to the two networks respectively, wherein the first indication information is used to indicate that the base station temporarily does not support the inter-RAT handover process;

[0412] Step S37: After the terminal terminates the RRC connection in any one of the networks, it sends a second indication message to the other network, where the second indication message is used to indicate that the inter-RAT handover capability is restored.

[0413] The first indication information and the second indication information may be reported through UAI. Whether they can be reported through UAI may also be network-configured, that is, the network may enable reporting of the first indication information and the second indication information;

[0414] The main implementation process on the network side includes:

[0415] When the network side receives the first indication information, it does not perform the inter-RAT handover process, that is, it does not send the inter-RAT handover command to the terminal;

[0416] After receiving the second indication information, the network side resumes the inter-RAT switching process, that is, it can send an inter-RAT switching command to the terminal.

[0417] Application scenario 4: After the terminal activates dual RRC connections, it prevents inter-RAT switching by not reporting the inter-RAT switching capability.

[0418] Steps S41 to S43 are the same as steps S11 to S13 in application scenario 1;

[0419] Step S44: After the terminal enters the dual registration mode, the terminal triggers reporting capability updates to the two networks through UECapabilityInformation. The updated terminal capabilities include: the terminal does not support inter-RAT handover capability;

[0420] Step S46: The terminal exits the dual registration mode and enters the single registration mode, for example, maintaining registration and RRC connection only in NR;

[0421] Step S47: The terminal triggers reporting capability update to the first network through UECapabilityInformation, where the updated terminal capability includes: the terminal supports inter-RAT switching capability.

[0422] It should be noted that, for terminals that support multiple registrations, in the embodiments of the present application, when registering for multiple networks at the same time, one or more of the networks can be suspended when there is no data transmission demand. When the terminal perceives that the transmission quality is poor, the transmission rate is low, the amount of data to be transmitted is large, and / or the service characteristics require the activation of multiple RRC transmissions in the currently used network, it will initiate an RRC connection establishment to another network, thereby reducing the communication delay caused by the registration process and improving the data transmission reliability.

[0423] As shown in FIG3 , an embodiment of the present application provides a communication processing method, including:

[0424] Step 301: The second access network device performs a radio resource control (RRC) connection establishment process or an RRC connection recovery process.

[0425] The RRC connection establishment process or the RRC connection recovery process is triggered when the terminal is registered with at least two networks, and the terminal is in an RRC connected state under the first network, and the terminal is in an RRC idle state or an RRC inactive state under the second network, and the first condition is met, and the second access network device belongs to the second network;

[0426] The at least two networks include the first network and the second network, and different networks belong to the same or different access network technologies;

[0427] The first condition includes at least one of the following:

[0428] The signal quality of the terminal in the cell of the first network is lower than or equal to a first measurement threshold;

[0429] The service rate of the terminal in the cell of the first network is lower than or equal to the first service rate threshold;

[0430] The to-be-sent service rate of the terminal in the first network is higher than or equal to a second service rate threshold;

[0431] The service characteristics of the pending service require the activation of dual-multi RRC transmission;

[0432] The signal quality of the terminal in the cell of the second network is higher than or equal to a second measurement threshold;

[0433] The service rate of the terminal in the cell in the second network is higher than or equal to a third service rate threshold.

[0434] Optionally, the second access network device performs a radio resource control RRC connection establishment process or an RRC connection recovery process, including:

[0435] The second access network device receives an RRC connection establishment request message or an RRC connection recovery request message sent by the terminal;

[0436] Among them, the RRC connection establishment request reason or RRC recovery reason carried in the RRC connection establishment request message or the RRC connection recovery request message includes: the link coverage of the first network is poor, and a request is made to establish an RRC connection under the second network; or, the terminal has business data to be transmitted and an RRC connection under the second network needs to be established.

[0437] Optionally, the method further includes:

[0438] The second access network device receives the first indication information or the first terminal capability update information sent by the terminal;

[0439] The first indication information is used to indicate that the switching capability between temporary radio access technologies is not supported; and the first terminal capability update is used to update the switching capability between radio access technologies of the terminal.

[0440] Optionally, the method further includes:

[0441] The second access network device receives second indication information or second terminal capability update information sent by the terminal;

[0442] The second indication information is used to indicate that the inter-radio access technology handover capability is restored; and the second terminal capability update information is used to update the terminal to have the inter-radio access technology handover capability.

[0443] It should be noted that all descriptions about the second access network device side in the above embodiments are applicable to the embodiments of the communication processing method applied to the second access network device side, and can achieve the same technical effects, so they will not be repeated here.

[0444] As shown in FIG4 , an embodiment of the present application provides an information transmission method, including:

[0445] Step 401: A third core network device or a third access network device sends first configuration information to a terminal.

[0446] The third core network device or the third access network device belongs to a third network, and the third network is a network that the terminal registered to access before registering to access at least two networks;

[0447] Optionally, the third network may also be the access network that the terminal first registers when registering to access at least two networks;

[0448] The first configuration information includes at least one of the following:

[0449] third indication information, where the third indication information is used to indicate that the terminal is allowed to register and access at least two networks;

[0450] First measurement threshold;

[0451] A first service rate threshold;

[0452] Second service rate threshold.

[0453] Second measurement threshold;

[0454] The third service rate.

[0455] Optionally, before the third core network device or the third access network device sends the first configuration information to the terminal, the method further includes:

[0456] The third core network device or the third access network device receives fourth indication information sent by the terminal, where the fourth indication information is used to indicate that the terminal supports registration and access to at least two networks.

[0457] Optionally, the third core network device receives the fifth indication information sent by the fourth core network device under the fourth network, indicating that the terminal has completed registration with the fourth network, and the third core network device optionally sends the fifth indication information to the third access network device.

[0458] The fourth network is a network on which the terminal initiates at least two registrations.

[0459] It should be noted that all descriptions about the third core network device or the third access network device side in the above embodiments are applicable to the embodiments of the information transmission method applied to the third core network device or the third access network device side, and can achieve the same technical effects, so they will not be repeated here.

[0460] As shown in FIG5 , an embodiment of the present application provides a communication processing method, including:

[0461] Step 501: After registering with at least two networks, the terminal sends first indication information or first terminal capability update information to an access network device corresponding to a target network among the at least two networks, where the target network is at least one network among the at least two networks with which an RRC connection is established.

[0462] The first indication information is used to indicate that the handover capability between temporary radio access technologies is not supported; the first terminal capability update information is used to update the handover capability between radio access technologies of the terminal;

[0463] Different networks belong to the same or different access network technologies.

[0464] It should be noted that the not supporting the switching capability between temporary radio access technologies can be understood as not being able to configure switching between radio access technologies in the current case of multiple RRC connections.

[0465] It should be noted that the embodiments of the present application can avoid inter-RAT switching when the terminal is in a dual-registration mode or a multi-registration mode.

[0466] Optionally, in order to solve this problem in the embodiments of the present application, one of the following implementations may be adopted:

[0467] Implementation method 1: Sending the first instruction information

[0468] Typically, the terminal needs to send first indication information to all networks with which the RRC connection is established, and the terminal cannot perform inter-RAT handover in each network.

[0469] After the access network device receives the first indication information sent by the terminal, the access network device determines that inter-RAT cell handover of the terminal is not possible. Optionally, in one case, the terminal does not configure inter-RAT measurement parameters (i.e., measurement configuration information) when configuring cell measurement parameters. The terminal then knows that when performing cell measurement in the current network, it will not measure cells that do not belong to the same RAT or cells that are of a different RAT from the current serving cell. Therefore, when reporting measurements to the access network device, the terminal does not report measurement results of cells of a different RAT from the current serving cell. Consequently, the access network device will not select an inter-RAT cell when selecting a handover cell, thereby ensuring that inter-RAT handover is not triggered. Optionally, in another case, when knowing that inter-RAT cell handover is not possible, the access network device may configure measurement parameters normally, that is, may configure inter-RAT measurement configuration information to the terminal. The terminal may perform measurement reporting according to the measurement parameters configured by the access network device. However, when selecting a handover cell, the base station will not select an inter-RAT cell, thereby ensuring that the terminal does not switch to an inter-RAT cell.

[0470] Optionally, in this case, in one implementation, the method further includes:

[0471] When the target network becomes the only registered network of the terminal, or is the only network with which an RRC connection is established among the at least two registered networks, the terminal sends second indication information to the access network device, where the second indication information is used to indicate the restoration of the switching capability between radio access technologies.

[0472] That is, when the terminal exits the multi-registration mode, it needs to send a second indication message to the currently connected access network device to inform the access network device that the inter-radio access technology switching capability is restored, that is, it can configure inter-RAT switching when performing cell switching.

[0473] Implementation method 1: Sending first terminal capability update information

[0474] Typically, the terminal needs to send first terminal capability update information to all networks with which the RRC connection is established, and the terminal cannot perform inter-RAT handover in each network.

[0475] It should be noted here that when the terminal capability stored on the access network device side is the terminal's support for switching between wireless access technologies, after receiving the first terminal capability update information, the terminal capability needs to be updated to the terminal's non-support for switching between wireless access technologies.

[0476] After the access network device receives the first terminal capability update information sent by the terminal, the access network device determines that inter-RAT cell handover of the terminal is not possible. Optionally, in one case, the terminal does not configure inter-RAT measurement parameters (i.e., measurement configuration information) when configuring cell measurement parameters. The terminal then knows not to measure cells that do not belong to the same RAT or do not measure cells with a different RAT from the current serving cell when performing cell measurement in the current network. Therefore, when reporting measurements to the access network device, the terminal does not report measurement results of cells with a different RAT from the current serving cell. Consequently, when the access network selects a handover cell, the access network does not select an inter-RAT cell, thereby ensuring that inter-RAT handover is not triggered. Optionally, in another case, when the access network device knows that inter-RAT cell handover is not possible, the access network device may configure measurement parameters normally, i.e., may configure inter-RAT measurement configuration information to the terminal. The terminal may perform measurement reporting according to the measurement parameters configured by the access network device. However, when the base station selects a handover cell, the base station does not select an inter-RAT cell, thereby ensuring that the terminal does not switch to an inter-RAT cell.

[0477] Optionally, in this case, in one implementation, the method further includes:

[0478] When the target network becomes the only registered network of the terminal, or is the only network with which an RRC connection is established among the at least two registered networks, the terminal sends second terminal capability update information to the access network device, where the second terminal capability update information is used to update the terminal's switching capability between wireless access technologies.

[0479] It should be noted here that when the terminal capability stored on the second access network device side is that the terminal does not support switching capabilities between wireless access technologies, after receiving the second terminal capability update information, the terminal capability needs to be updated to support switching capabilities between wireless access technologies.

[0480] That is to say, when the terminal exits the multi-registration mode, it needs to send the second terminal capability update information to the currently connected access network device to inform the access network device that the terminal can switch between wireless access technologies, that is, it can configure cross-RAT switching when performing cell switching.

[0481] Implementation method 3: After registering with at least two networks, the terminal receives second configuration information sent by the access network device corresponding to the target network in the at least two networks, and the second configuration information does not include inter-RAT measurement configuration information

[0482] It should be noted that by sending measurement configuration information that does not include inter-RAT to the terminal, the terminal will know that when performing cell measurement under the current network, it will not measure cells that do not belong to the same RAT or cells with a different RAT from the current serving cell. Therefore, when reporting measurements to the access network device, the measurement results of cells with a different RAT from the current serving cell will not be reported. Then, when the access network device selects a switching cell, it will not select a cross-RAT cell, thereby ensuring that inter-RAT switching will not be triggered.

[0483] Optionally, in this case, the fifth core network device needs to send fifth indication information to the fourth core network device;

[0484] The fourth core network device belongs to the first network, the fifth core network device belongs to the second network, the first network and the second network are both networks registered and accessed by the terminal, and the terminal registers and accesses the first network earlier than the second network;

[0485] The fifth indication information includes at least one of the following:

[0486] identification information of the terminal;

[0487] An indication that the terminal has completed registration with the second network.

[0488] Furthermore, after receiving the fifth indication information sent by the fifth core network device, the fourth core network device sends a sixth indication information to the access network device, where the sixth indication information is used to instruct the terminal to complete registration and access at least two networks; and then the access network device sends the second configuration information to the terminal.

[0489] The following takes the terminal performing dual registration as an example to illustrate the specific application of the embodiment of the present application.

[0490] Application scenario 1: After the terminal activates dual RRC connections, network configuration is used to prevent inter-RAT switching

[0491] Step S111: The current terminal is in single registration mode to access the first network, and the terminal reports to the currently accessed network that it supports dual registration; for example, the first network accessed by the terminal is a 5GC and NR base station.

[0492] Optionally, the terminal may report fourth indication information to the core network or report fourth indication information to the base station, where the fourth indication information is used to indicate that the terminal supports registration and access to two networks.

[0493] Step S112: The terminal receives first configuration information, where the first configuration information includes at least one of the following:

[0494] First indication information, the first indication information is used to indicate that the terminal is allowed to register and access two networks, that is, the terminal can perform dual registration;

[0495] First measurement threshold;

[0496] A first service rate threshold;

[0497] Second service rate threshold;

[0498] Second measurement threshold;

[0499] The third service rate.

[0500] The first configuration information may be sent by the core network of the first network through a NAS message; optionally, the first configuration information may also be configured by the base station of the first network through an RRC message.

[0501] Step S113: If the terminal receives the first configuration information through a NAS message, the NAS layer of the terminal forwards the first configuration information to the RRC layer of the terminal;

[0502] Step S114: The terminal completes registration with the second network, and an N26 interface is established between the two core networks (AMF and MME).

[0503] Step S115: The terminal receives UECapabilityEnquiry signaling from the two networks respectively;

[0504] Step S116: The terminal reports its capabilities to the two networks respectively through UECapabilityInformation, including inter-RAT handover capability.

[0505] Step S117: The terminal receives second configuration information of the two networks respectively, where the second configuration information does not include inter-RAT measurement configuration information;

[0506] Furthermore, after the terminal completes the second network registration, the main implementation process on the network side includes:

[0507] Step S1101: The AMF receives fifth indication information, where the fifth indication information is sent by the MME to the AMF, and the indication information includes at least one of the following:

[0508] Identification information of the terminal, such as 5G-GUTI, etc.;

[0509] The terminal has completed the second network registration indication.

[0510] Step S1102: The AMF indicates to the NR base station that the terminal has completed dual registration.

[0511] Step S1103: The NR base station and the LTE base station respectively send second configuration information to the terminal, where the second configuration information does not include inter-RAT measurement configuration information.

[0512] Application scenario 2: After the terminal activates the dual RRC connection, the terminal indicates information to prevent inter-RAT switching

[0513] Steps S211 to S213 are the same as steps S111 to S113 in application scenario 1;

[0514] Step S214: The terminal enters the dual registration mode and is in the RRC connected state in both networks. The terminal receives UECapabilityEnquiry signaling from the two networks respectively.

[0515] Step S215: The terminal reports its capabilities to the two networks respectively through UECapabilityInformation, including inter-RAT handover capability.

[0516] Step S216: The terminal reports first indication information to the two networks respectively, where the first indication information is used to indicate that the base station temporarily does not support the inter-RAT handover process;

[0517] Step S217: After the terminal terminates the RRC connection in any one of the networks, it sends a second indication message to the other network, where the second indication message is used to indicate that the inter-RAT handover capability is restored.

[0518] The first indication information and the second indication information may be reported through UAI. Whether they can be reported through UAI may also be network-configured, that is, the network may enable reporting of the first indication information and the second indication information;

[0519] The main implementation process on the network side includes:

[0520] When the network side receives the first indication information, it does not perform the inter-RAT handover process, that is, it does not send the inter-RAT handover command to the terminal;

[0521] After receiving the second indication information, the network side resumes the inter-RAT switching process, that is, it can send an inter-RAT switching command to the terminal.

[0522] Application scenario 3: After the terminal activates dual RRC connections, it prevents inter-RAT switching by not reporting the inter-RAT switching capability.

[0523] Steps S311 to S313 are the same as steps S111 to S113 in application scenario 1;

[0524] Step S314: After the terminal enters the dual registration mode, the terminal triggers reporting capability updates to the two networks through UECapabilityInformation. The updated terminal capabilities include: the terminal does not support inter-RAT handover capability;

[0525] Step S316: The terminal exits the dual registration mode and enters the single registration mode, for example, maintaining registration and RRC connection only in NR;

[0526] Step S318: The terminal triggers reporting capability update to the first network through UECapabilityInformation, where the updated terminal capability includes: the terminal supports inter-RAT switching capability.

[0527] It should be noted that the embodiments of the present application can effectively prevent the terminal from performing cross-RAT switching in the multi-registration mode, ensure that the terminal uses the same RAT cell for service in the same network, and ensure data transmission reliability.

[0528] As shown in FIG6 , an embodiment of the present application provides an information transmission method, including:

[0529] Step 601: An access network device receives fifth indication information sent by a fourth core network device, where the fifth indication information is used to instruct a terminal to complete registration and access at least two networks, and the fourth core network device and the access network device belong to the same network; or

[0530] The access network device receives the first indication information or the first terminal capability update information sent by the terminal;

[0531] Among them, the first indication information or the first terminal capability update information is sent by the terminal to the access network device corresponding to the target network among the at least two networks after registering and accessing at least two networks. The target network is at least one network among the at least two networks to establish an RRC connection. The first indication information is used to indicate that the switching capability between temporary wireless access technologies is not supported; the first terminal capability update is used to update the switching capability between wireless access technologies of the terminal, and different networks belong to the same or different access network technologies.

[0532] Optionally, after the access network device receives the first indication information or the first terminal capability update information sent by the terminal, the method further includes:

[0533] The access network device receives the second indication information or the second terminal capability update information sent by the terminal;

[0534] The second indication information is used to indicate that the inter-radio access technology handover capability is restored; and the second terminal capability update information is used to update the terminal to have the inter-radio access technology handover capability.

[0535] It should be noted that all descriptions about the access network device side in the above embodiments are applicable to the embodiments of the information transmission method applied to the access network device side, and can achieve the same technical effects, so they will not be repeated here.

[0536] As shown in FIG7 , an embodiment of the present application provides an information transmission method, including:

[0537] Step 701: The fifth core network device sends fifth indication information to the fourth core network device.

[0538] The fourth core network device belongs to the first network, the fifth core network device belongs to the second network, the first network and the second network are both networks registered and accessed by the terminal, and the terminal registers and accesses the first network earlier than the second network;

[0539] The fifth indication information includes at least one of the following:

[0540] identification information of the terminal;

[0541] An indication that the terminal has completed registration with the second network.

[0542] It should be noted that all descriptions about the fifth core network device side in the above embodiments are applicable to the embodiments of the information transmission method applied to the fifth core network device side, and can achieve the same technical effects, so they will not be repeated here.

[0543] As shown in FIG8 , an embodiment of the present application provides an information transmission method, including:

[0544] Step 801: The fourth core network device receives fifth indication information sent by the fifth core network device;

[0545] The fourth core network device sends sixth indication information to the access network device, where the sixth indication information is used to instruct the terminal to complete registration and access at least two networks;

[0546] The fourth core network device belongs to a first network, the fifth core network device belongs to a second network, the first network and the second network are both networks registered and accessed by the terminal, and the terminal registers and accesses the first network earlier than the second network;

[0547] The fifth indication information includes at least one of the following:

[0548] identification information of the terminal;

[0549] The terminal has completed the second network registration indication.

[0550] It should be noted that all descriptions about the fourth core network device side in the above embodiments are applicable to the embodiments of the information transmission method applied to the fourth core network device side, and can achieve the same technical effects, so they will not be repeated here.

[0551] As shown in FIG19 , an embodiment of the present application provides a communication processing method, including:

[0552] Step 1901: When a terminal is registered with a first network and is in a radio resource control (RRC) connected state under a first access network device under the first network and is in an RRC idle state or an RRC inactive state under a second access network device under the first network, if a first condition is met, triggering initiation of an RRC connection establishment process or an RRC connection recovery process to the second access network device;

[0553] It should be noted that the terminal mentioned in the embodiment of the present application can be a terminal that can access two access network devices, or a terminal that can access more than two access network devices. Optionally, the access network devices accessed by the terminal can belong to the same or different access network technologies.

[0554] It should be noted that the access network device accessed by the terminal may belong to the same core network device. For example, in this embodiment, the first access network device and the second access network device accessed by the terminal may belong to the same core network device, such as both may be 5GC or 6G core networks in a 5G system.

[0555] It should also be noted that when the terminal supports multiple accesses, multiple access network devices can be accessed under the first network, for example, terminal 6G access network devices, 4G access network devices and 5G access network devices. The current terminal transmits the target service through the 6G access network device. When the first condition is met, the terminal can trigger the 5G access network device to initiate RRC connection establishment, and can also trigger the 4G access network device to initiate RRC connection establishment, or can simultaneously trigger the 5G access network device and the 4G access network device to initiate RRC connection establishment respectively.

[0556] In some embodiments, the first condition includes at least one of the following:

[0557] E11. The signal quality of the terminal in the cell of the first access network device is lower than or equal to a first measurement threshold;

[0558] Signal quality lower than or equal to the first measurement threshold can be understood as poor transmission quality. This situation can be understood as the transmission quality of the terminal under the current access network equipment is poor, and other networks need to be used to assist transmission in a timely manner.

[0559] E12. The service rate of the terminal in the cell of the first access network device is lower than or equal to the first service rate threshold;

[0560] A service rate lower than or equal to the first service rate threshold can be understood as a low transmission rate. This situation can be understood as the terminal's transmission rate under the current access network device is low, and other networks need to be used to assist in transmission in a timely manner.

[0561] E13. The service rate to be sent by the terminal in the first access network device is higher than or equal to the second service rate threshold;

[0562] The rate of the pending service is higher than or equal to the second service rate threshold, which can be understood as a higher transmission rate, that is, a larger amount of data to be transmitted. This situation can be understood as a larger amount of data to be transmitted by the terminal under the current access network device, and other network assistance is needed in a timely manner for transmission.

[0563] E14. The service characteristics of the pending service require the activation of multiple RRC transmissions;

[0564] In this case, whether to enable multiple RRC transmissions can be determined directly based on the service characteristics. The multiple RRC transmissions include two RRC transmissions (i.e., dual RRC transmissions) and / or more than two RRC transmissions. For example, if the service characteristics indicate that dual RRC transmissions need to be enabled, it is necessary to trigger the access network device of another network to initiate the RRC connection establishment process.

[0565] E15. The signal quality of the terminal in the cell of the second access network device is higher than or equal to a second measurement threshold;

[0566] The signal quality higher than or equal to the second measurement threshold can be understood as the transmission quality of the second access network device is better. This situation can be understood as the transmission quality of the terminal under the first access network device is poor, and the second access network device needs to be used in time to assist in transmission, and the signal quality of the second access network device is better.

[0567] E16. The service rate of the terminal in the cell of the second access network device is higher than or equal to a third service rate threshold;

[0568] The service rate is higher than or equal to the third service rate threshold, which can be understood as the service transmission rate of the second access network device is relatively low. In this case, it can be understood that the transmission rate of the terminal under the first access network device is low, and the second access network device needs to be used in time to assist in transmission, and the service rate of the second access network device is better.

[0569] It should be noted here that, when the second access network device is in RRC idle state, if the first condition is met, the RRC connection establishment process is triggered to the second access network device; when the second access network device is in RRC inactive state, if the first condition is met, the RRC connection recovery process is triggered to the second access network device.

[0570] Optionally, in one implementation, if the first condition is met, triggering the initiation of an RRC connection establishment process to the second access network device includes:

[0571] When the first condition is met, the terminal sends an RRC connection establishment request message or an RRC connection recovery request message to the second access network device;

[0572] Among them, the RRC connection establishment request reason or RRC recovery reason carried in the RRC connection establishment request message or the RRC connection recovery request message includes: the link coverage of the first access network device is poor, and a request is made to establish an RRC connection under the second access network device; or, the terminal has business data to be transmitted and an RRC connection needs to be established under the second access network device.

[0573] Optionally, the RRC connection establishment request message carries an RRC connection establishment request cause; and the RRC connection recovery request message carries an RRC recovery cause (the RRC recovery cause may also be referred to as an RRC connection recovery cause).

[0574] In a specific implementation, the RRC layer of the terminal first determines whether the first condition is met. If the RRC layer determines that the first condition is met, it triggers an indication to the NAS layer of the terminal, thereby causing the NAS to trigger a service request (Service Request). It should be noted that because the service request can only be executed when the terminal is in an RRC connected state, the terminal needs to be connected to the second access network device. Optionally, the implementation process specifically includes:

[0575] The RRC layer of the terminal sends an RRC connection establishment request message or an RRC connection recovery request message to the second access network device, and the RRC layer of the terminal receives the RRC connection establishment message or the RRC connection recovery request message sent by the second access network device; after the RRC of the terminal receives the RRC connection establishment message or the RRC connection recovery message, the RRC layer of the terminal will send an RRC connection establishment completion message or an RRC connection recovery completion message to the second access network device, and the terminal can access the second access network device, wherein the service request message of the NAS layer of the terminal can be included in the RRC connection establishment completion message or the RRC connection recovery completion message. After the core network device corresponding to the second access network device receives the service request message, it can execute the service request process to realize the transmission of the target service of the terminal.

[0576] It should be noted that the above is aimed at how to use multiple RRC connections for information transmission when the terminal is registered in one core network. It can realize multiple RRC connections in a single registration, thereby expanding the link coverage and service transmission rate.

[0577] Optionally, in one implementation, the method further includes:

[0578] The terminal receives third configuration information before accessing at least two access network devices;

[0579] Optionally, the third configuration information includes at least one of the following:

[0580] seventh indication information, where the seventh indication information is used to indicate that the terminal is allowed to register and access at least two networks;

[0581] First measurement threshold;

[0582] A first service rate threshold;

[0583] Second service rate threshold;

[0584] Second measurement threshold;

[0585] The third service rate threshold.

[0586] Optionally, as long as the terminal receives any one or more of the above information, the terminal is allowed to access a new access network device.

[0587] Optionally, in one implementation, the receiving the third configuration information includes one of the following:

[0588] E21. The terminal receives third configuration information sent by a sixth core network device corresponding to the sixth network through a NAS message;

[0589] This situation can be understood as that the third configuration information is configured by the core network device. After configuring the third configuration information, the core network device needs to send the third configuration information to the terminal through a NAS message.

[0590] It should be noted that, since it is the RRC layer of the terminal that ultimately uses the third configuration information, the NAS layer of the terminal needs to forward the third configuration information to the RRC layer of the terminal after receiving the third configuration information.

[0591] It should be noted that the sixth network and the first network may be the same or different, that is, the third configuration information received by the terminal may come from the core network device of the registered first network or from the core network device of other networks.

[0592] E22. The terminal receives third configuration information sent by a sixth access network device corresponding to the sixth network through an RRC message;

[0593] This situation can be understood as the third configuration information is configured by the access network device. After configuring the third configuration information, the access network device needs to send the third configuration information to the terminal through an RRC message, and the RRC layer of the terminal finally receives the third configuration information.

[0594] It should be noted that the sixth access network device may be at least one access network device accessed by the terminal, such as the first access network device or the second access network device.

[0595] Optionally, before receiving the third configuration information, the method further includes:

[0596] Send eighth indication information to the sixth core network device or the sixth access network device, where the eighth indication information is used to indicate that the terminal supports access to at least two core network devices.

[0597] It should be noted that after the sixth core network device or the sixth access network device receives the eighth indication information, it can configure the first configuration information for the terminal.

[0598] Optionally, when the terminal sends the eighth indication information to the sixth core network device, the third configuration information is sent by the sixth core network device to the terminal; optionally, when the terminal sends the eighth indication information to the sixth access network device, the third configuration information is sent by the sixth access network device to the terminal.

[0599] It should be noted that the terminal can determine when to initiate an RRC connection to the second access network device according to the trigger condition configured in the third configuration information.

[0600] It should be noted that when the terminal accesses at least one access network device at the same time, it is necessary to avoid inter-radio access technology (inter-RAT) switching. Optionally, in order to solve this problem in the embodiment of the present application, one of the following implementation methods can be adopted:

[0601] Implementation method 1:

[0602] The terminal receives, respectively, second configuration information sent by each access network device in a network with which the terminal has an RRC connection, in at least two access network devices, where the second configuration information does not include inter-RAT measurement configuration information;

[0603] It should be noted that by sending measurement configuration information that does not include inter-RAT to the terminal, the terminal will know that when performing cell measurement under the current access network device, the cell with a different RAT from the current serving cell will not be measured. Therefore, when reporting the measurement to the access network device, the measurement results of the cell with a different RAT from the current serving cell will not be reported. Then, when the access network device selects a switching cell, it will not select a cross-RAT cell, thereby ensuring that inter-RAT switching will not be triggered.

[0604] Optionally, in this case, if the terminal completes access under the second access network device, the core network device needs to send a ninth indication message to the first access network device, and the ninth indication message is used to instruct the terminal to complete access to at least two access network devices, after which the first access network device and the second access network device respectively send second configuration information to the terminal.

[0605] Implementation method 2:

[0606] After establishing an RRC connection with the second access network device, the terminal reports first indication information to the second access network device, where the first indication information is used to indicate that a switching capability between temporary radio access technologies is not supported.

[0607] It should be noted that the not supporting temporary handover capability between radio access technologies can be understood as not being able to configure measurement configuration of cells between radio access technologies in the current case of multiple RRC connections.

[0608] It should also be noted here that after the terminal establishes an RRC connection with the first access network device, it also needs to report first indication information to the first access network device, where the first indication information is used to indicate that the switching capability between temporary wireless access technologies is not supported.

[0609] That is to say, in the case of multiple RRC connections, the terminal needs to send the first indication information to the access network device corresponding to each network, and the terminal cannot perform inter-RAT switching in each network.

[0610] After the access network device receives the first indication information sent by the terminal, the access network device determines that inter-RAT cell handover of the terminal is not possible. Optionally, in one case, the terminal does not configure inter-RAT measurement parameters (i.e., measurement configuration information) when configuring cell measurement parameters. The terminal then knows that when performing cell measurement in the current network, it will not measure cells that do not belong to the same RAT or cells that are of a different RAT from the current serving cell. Therefore, when reporting measurements to the access network device, the terminal does not report measurement results of cells of a different RAT from the current serving cell. Consequently, the access network device will not select an inter-RAT cell when selecting a handover cell, thereby ensuring that inter-RAT handover is not triggered. Optionally, in another case, when knowing that inter-RAT cell handover is not possible, the access network device may configure measurement parameters normally, that is, may configure inter-RAT measurement configuration information to the terminal. The terminal may perform measurement reporting according to the measurement parameters configured by the access network device. However, when selecting a handover cell, the access network device will not select an inter-RAT cell, thereby ensuring that the terminal does not switch to an inter-RAT cell.

[0611] Optionally, in this case, in one implementation, the method further includes:

[0612] When the second access network device becomes the only network accessed by the terminal, or is the only network to which an RRC connection is established among the at least two core network devices accessed, the terminal sends a second indication message to the second access network device; the second indication message is used to indicate that the handover capability between radio access technologies is restored.

[0613] That is to say, when the terminal exits the multi-access mode, it needs to send a second indication message to the currently connected access network device to inform the access network device that the switching capability between wireless access technologies has been restored, that is, it can configure cross-RAT switching when performing cell switching.

[0614] Among them, the second access network device is not limited to the access network device that initiates RRC connection establishment or connection recovery or initiates connection after the terminal. The second access network device can also be the access network device during the initial single access, that is, the second access network device can be the access network device to which any terminal connects after restoring single access.

[0615] Implementation method three:

[0616] After establishing an RRC connection with the second access network device, the terminal reports first terminal capability update information to the second access network device, where the first terminal capability update is used to update the handover capability of the terminal between radio access technologies.

[0617] It should be noted that, it can be understood here that after the terminal establishes an RRC connection with the second access network device, it needs to initiate a first terminal capability update process, and when initiating the first terminal capability update process, the terminal needs to send the first terminal capability update information to the second access network device.

[0618] It should be noted here that when the terminal capability stored on the second access network device side is the terminal's support for switching between wireless access technologies, after receiving the first terminal capability update information, the terminal capability needs to be updated to the terminal's non-support for switching between wireless access technologies.

[0619] It should also be noted here that after the terminal establishes an RRC connection with the first access network device, it also needs to initiate a first terminal capability update process to the first access network device, that is, the terminal sends the first terminal capability update information to the first access network device.

[0620] That is, in the case of multiple RRC connections, the terminal needs to send the first terminal capability update information to each access network device, and the terminal cannot perform inter-RAT switching in each network.

[0621] After the access network device receives the first terminal capability update information sent by the terminal, the access network device determines that inter-RAT cell handover of the terminal is not possible. Optionally, in one case, the terminal does not configure inter-RAT measurement parameters (i.e., measurement configuration information) when configuring cell measurement parameters. The terminal then knows not to measure cells that do not belong to the same RAT or do not measure cells with a different RAT from the current serving cell when performing cell measurement in the current network. Therefore, when reporting measurements to the access network device, the terminal does not report measurement results of cells with a different RAT from the current serving cell. Consequently, when selecting a handover cell, the access network device does not select an inter-RAT cell, thereby ensuring that inter-RAT handover is not triggered. Optionally, in another case, when knowing that inter-RAT cell handover is not possible, the access network device may configure measurement parameters normally, i.e., configure inter-RAT measurement configuration information to the terminal. The terminal may perform measurement reporting according to the measurement parameters configured by the access network device. However, when selecting a handover cell, the base station does not select an inter-RAT cell, thereby ensuring that the terminal does not switch to an inter-RAT cell.

[0622] Optionally, in this case, in one implementation, the method further includes:

[0623] When the second access network device becomes the only access network device accessed by the terminal, or is the only access network device to which an RRC connection is established among the at least two access network devices accessed, the terminal sends second terminal capability update information to the second access network device; the second terminal capability update information is used to update the terminal's switching capability between wireless access technologies.

[0624] It should be noted that, it can be understood here that when the second network becomes the only network accessed by the terminal, or is the only network to which an RRC connection is established among the at least two access network devices accessed, the terminal needs to initiate a second terminal capability update process, and when initiating the second terminal capability update process, the terminal needs to send the second terminal capability update information to the second access network device.

[0625] It should be noted here that when the terminal capability stored on the second access network device side is that the terminal does not support switching capabilities between wireless access technologies, after receiving the second terminal capability update information, the terminal capability needs to be updated to support switching capabilities between wireless access technologies.

[0626] Among them, the second access network device is not limited to the access network device that initiates RRC connection establishment or connection recovery or initiates access after the terminal. The second access network device can also be the access network device during the initial single access, that is, the second access network device can be the access network device to which any terminal connects after restoring single access.

[0627] That is to say, when the terminal exits the multi-access mode, it needs to send the second terminal capability update information to the currently connected access network device to inform the access network device that the terminal can switch between wireless access technologies, that is, it can configure cross-RAT switching when performing cell switching.

[0628] Referring to FIG. 20 , a communication processing method according to an embodiment of the present application includes:

[0629] Step 2001: The second access network device performs a radio resource control RRC connection establishment process or an RRC connection recovery process;

[0630] The RRC connection establishment process or the RRC connection recovery process is triggered when the terminal accesses at least two access network devices, and the terminal is in an RRC connected state under the first access network device, and the terminal is in an RRC idle state or an RRC inactive state under the second access network device, and the first condition is met;

[0631] The first condition includes at least one of the following:

[0632] The signal quality of the terminal in the cell of the first access network device is lower than or equal to a first measurement threshold;

[0633] The service rate of the terminal in the cell of the first access network device is lower than or equal to the first service rate threshold;

[0634] The service rate to be sent by the terminal in the first access network device is higher than or equal to the second service rate threshold;

[0635] The service characteristics of the pending service require the activation of dual-multi RRC transmission;

[0636] The signal quality of the terminal in the cell of the second access network device is higher than or equal to a second measurement threshold;

[0637] The service rate of the terminal in the cell of the second access network device is higher than or equal to a third service rate threshold.

[0638] Optionally, the second access network device performs a radio resource control RRC connection establishment process or an RRC connection recovery process, including:

[0639] The second access network device receives an RRC connection establishment request message or an RRC connection recovery request message sent by the terminal;

[0640] Among them, the RRC connection establishment request reason or RRC recovery reason carried in the RRC connection establishment request message or the RRC connection recovery request message includes: the link coverage of the first access network device is poor, and a request is made to establish an RRC connection under the second access network device; or, the terminal has business data to be transmitted and an RRC connection needs to be established under the second access network device.

[0641] Optionally, the method further includes:

[0642] The second access network device receives the first indication information or the first terminal capability update information sent by the terminal;

[0643] The first indication information is used to indicate that the switching capability between temporary radio access technologies is not supported; and the first terminal capability update is used to update the switching capability between radio access technologies of the terminal.

[0644] Optionally, the method further includes:

[0646] The second indication information is used to indicate that the inter-radio access technology handover capability is restored; and the second terminal capability update information is used to update the terminal to have the inter-radio access technology handover capability.

[0647] It should be noted that all descriptions about the second access network device side in the above embodiments are applicable to the embodiments of the communication processing method applied to the second access network device side, and can achieve the same technical effects, so they will not be repeated here.

[0648] Referring to FIG. 21 , an embodiment of the present application provides an information transmission method, including:

[0649] Step 2101: The sixth core network device or the sixth access network device sends third configuration information to the terminal;

[0650] The sixth core network device or the sixth access network device is a network registered or accessed by the terminal before accessing at least two access network devices;

[0651] Optionally, the sixth core network device or the sixth access network device may also be the access network device that the terminal first accesses when accessing at least two access network devices;

[0652] The third configuration information includes at least one of the following:

[0653] seventh indication information, where the seventh indication information is used to indicate that the terminal is allowed to access at least two access network devices;

[0654] First measurement threshold;

[0655] A first service rate threshold;

[0656] Second service rate threshold.

[0660] The sixth core network device or the sixth access network device receives the eighth indication information sent by the terminal, where the eighth indication information is used to indicate that the terminal supports access to at least two access network devices.

[0661] It should be noted that all descriptions about the sixth core network device or the sixth access network device side in the above embodiments are applicable to the embodiments of the information transmission method applied to the sixth core network device or the sixth access network device side, and can achieve the same technical effects, so they will not be repeated here.

[0662] Referring to FIG. 22 , an embodiment of the present application provides an information transmission method, including:

[0663] Step 2201: After accessing at least two access network devices, the terminal sends first indication information or first terminal capability update information to a target access network device among the at least two access network devices, where the target access network device is at least one network among the at least two access network devices to which an RRC connection is established.

[0664] The first indication information is used to indicate that the handover capability between temporary radio access technologies is not supported; the first terminal capability update is used to update the handover capability between radio access technologies of the terminal;

[0665] Different access network devices belong to the same or different access network technologies.

[0666] It should be noted that the not supporting the switching capability between temporary radio access technologies can be understood as not being able to configure switching between radio access technologies in the current case of multiple RRC connections.

[0667] It should be noted that the embodiments of the present application can avoid inter-RAT switching when the terminal is in a multi-access mode with a single registration mode.

[0668] Optionally, in order to solve this problem in the embodiments of the present application, one of the following implementations may be adopted:

[0669] Implementation method 1: Sending the first instruction information

[0670] Typically, the terminal needs to send first indication information to all access network devices with which the RRC connection is established, and the terminal cannot perform inter-RAT handover in each access network device.

[0671] After the access network device receives the first indication information sent by the terminal, the access network device determines that inter-RAT cell handover of the terminal is not possible. Optionally, in one case, the terminal does not configure inter-RAT measurement parameters (i.e., measurement configuration information) when configuring cell measurement parameters. The terminal then knows that when performing cell measurement in the current network, it will not measure cells that do not belong to the same RAT or cells that are of a different RAT from the current serving cell. Therefore, when reporting measurements to the access network device, the terminal does not report measurement results of cells of a different RAT from the current serving cell. Consequently, the access network device will not select an inter-RAT cell when selecting a handover cell, thereby ensuring that inter-RAT handover is not triggered. Optionally, in another case, when knowing that inter-RAT cell handover is not possible, the access network device may configure measurement parameters normally, that is, may configure inter-RAT measurement configuration information to the terminal. The terminal may perform measurement reporting according to the measurement parameters configured by the access network device. However, when selecting a handover cell, the base station will not select an inter-RAT cell, thereby ensuring that the terminal does not switch to an inter-RAT cell.

[0672] Optionally, in this case, in one implementation, the method further includes:

[0673] When the target access network device becomes the only access network device accessed by the terminal, or is the only access network device to which an RRC connection is established among the at least two access network devices accessed, the terminal sends second indication information to the access network device, where the second indication information is used to indicate the recovery of the switching capability between wireless access technologies.

[0674] That is to say, when the terminal is in multi-access mode, it is necessary to send second indication information to the currently connected access network device to inform the access network device that the switching capability between wireless access technologies has been restored, that is, it can configure cross-RAT switching when performing cell switching.

[0675] Implementation method 1: Sending first terminal capability update information

[0676] Typically, the terminal needs to send first terminal capability update information to all access network devices with which RRC connections are established, and the terminal cannot perform inter-RAT handover in each access network device.

[0677] It should be noted here that when the terminal capability stored on the access network device side is the terminal's support for switching between wireless access technologies, after receiving the first terminal capability update information, the terminal capability needs to be updated to the terminal's non-support for switching between wireless access technologies.

[0678] After the access network device receives the first terminal capability update information sent by the terminal, the access network device determines that inter-RAT cell handover of the terminal is not possible. Optionally, in one case, the terminal does not configure inter-RAT measurement parameters (i.e., measurement configuration information) when configuring cell measurement parameters. The terminal then knows not to measure cells that do not belong to the same RAT or do not measure cells with a different RAT from the current serving cell when performing cell measurement in the current network. Therefore, when reporting measurements to the access network device, the terminal does not report measurement results of cells with a different RAT from the current serving cell. Consequently, when the access network selects a handover cell, the access network does not select an inter-RAT cell, thereby ensuring that inter-RAT handover is not triggered. Optionally, in another case, when the access network device knows that inter-RAT cell handover is not possible, the access network device may configure measurement parameters normally, i.e., may configure inter-RAT measurement configuration information to the terminal. The terminal may perform measurement reporting according to the measurement parameters configured by the access network device. However, when the base station selects a handover cell, the base station does not select an inter-RAT cell, thereby ensuring that the terminal does not switch to an inter-RAT cell.

[0679] Optionally, in this case, in one implementation, the method further includes:

[0680] When the target access network device becomes the only access network device accessed by the terminal, or is the only access network device to which an RRC connection is established among the at least two access network devices accessed, the terminal sends second terminal capability update information to the access network device, and the second terminal capability update information is used to update the terminal's switching capability between wireless access technologies.

[0681] It should be noted here that when the terminal capability stored on the second access network device side is that the terminal does not support switching capabilities between wireless access technologies, after receiving the second terminal capability update information, the terminal capability needs to be updated to support switching capabilities between wireless access technologies.

[0682] That is to say, when the terminal exits the multi-access mode, it needs to send the second terminal capability update information to the currently connected access network device to inform the access network device that the terminal can switch between wireless access technologies, that is, it can configure cross-RAT switching when performing cell switching.

[0683] Implementation method three: After the terminal accesses at least two access network devices, it receives the second configuration information sent by the target access network device among the at least two access network devices, and the second configuration information does not include the inter-RAT measurement configuration information

[0684] It should be noted that by sending measurement configuration information that does not include inter-RAT to the terminal, the terminal will know that when performing cell measurement under the current network, it will not measure cells that do not belong to the same RAT or cells with a different RAT from the current serving cell. Therefore, when reporting measurements to the access network device, the measurement results of cells with a different RAT from the current serving cell will not be reported. Then, when the access network device selects a switching cell, it will not select a cross-RAT cell, thereby ensuring that inter-RAT switching will not be triggered.

[0685] Referring to FIG. 23 , an embodiment of the present application provides an information transmission method, including:

[0686] Step 2301: The access network device receives ninth indication information sent by a seventh core network device, where the ninth indication information is used to indicate that the terminal has completed access to at least two access network devices, and the seventh core network device and the access network device belong to the same network; or the access network device receives first indication information or first terminal capability update information sent by the terminal;

[0687] Among them, the first indication information or the first terminal capability update information is sent by the terminal to the target access network device among the at least two access network devices after accessing the at least two access network devices. The target access network device is at least one access network device that establishes an RRC connection among the at least two access network devices. The first indication information is used to indicate that the switching capability between temporary wireless access technologies is not supported; the first terminal capability update is used to update the switching capability between wireless access technologies of the terminal, and different access network devices belong to the same or different access network technologies.

[0688] Optionally, after the access network device receives the first indication information or the first terminal capability update information sent by the terminal, the method further includes:

[0689] The access network device receives the second indication information or the second terminal capability update information sent by the terminal;

[0690] The second indication information is used to indicate that the inter-radio access technology handover capability is restored; and the second terminal capability update information is used to update the terminal to have the inter-radio access technology handover capability.
