It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0049] The core network device can also be referred to as a core network node, a core network function, or a core network network element, etc., which includes but is not limited to at least one of the following: a mobility management entity (MME), an access and mobility management function (AMF), a session management function (SMF), a user plane function (UPF), a policy control function (PCF), a policy and charging rules function (PCRF), an edge application server discovery function (EASDF), a unified data management (UDM), a unified data repository (UDR), a home subscriber server (HSS), a centralized network configuration (CNC), a network repository function (NRF), a network exposure function (NEF), a local NEF (L-NEF), a binding support function (BSF), an application function (AF), a location management function (LMF), a gateway mobile location center (GMLC), a network data analytics function (NWDAF), etc. It should be noted that only the core network device in the NR system is taken as an example for introduction in the embodiments of the present application, and the specific type of the core network device is not limited. If the name of the core network device mentioned in the embodiments of the present application changes in the subsequent protocol version (for example, 6G), it is also within the protection scope of the present application.

[0050] Optionally, the core network device can be implemented by one or more function modules in one device, or can be implemented by multiple devices together, and the embodiments of the present application do not make a specific limitation in this regard. It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a dedicated hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0051] The transmission processing method, apparatus, terminal and network side device provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings, some embodiments and application scenarios.

[0052] At present, a terminal can perform switching between networks of different modes. For example, the terminal can switch from a 5G network to a 4G network, and the specific switching process is as follows:

[0053] 1. The 5G base station NG RAN determines to switch the terminal to 4G according to the measurement result reported by the terminal, and sends a switching indication to the AMF currently providing services for the terminal.

[0054] 2. The AMF requests the SMF+PGW-C serving the terminal to provide context information of a public data network (PDN) connection corresponding to a protocol data unit (PDU) session of the terminal.

[0055] If the terminal is in a roaming state, the context information is sent to the SMF+PGW-C by the SMF serving the terminal in the visited public land mobile network (VPLMN). If the terminal is in a roaming state, the SMF+PGW-C can be located in the home public land mobile network (HPLMN) of the terminal.

[0056] 3. The AMF sends a Forward Relocation Request to the MME, and the request contains context information of the terminal, including information of a PDN connection corresponding to a PDU session of the terminal, and the information of the PDN connection contains information of an EPS bearer, such as GBR or MBR information of the EPS bearer.

[0057] It should be noted that the PDU session is a concept of 5G, and the corresponding concept of 4G is a PDN connection. Each PDU session can contain one or more QoS flows (i.e., quality of service flows), and each QoS flow can support a QoS, for example, a voice service is a QoS flow with a QoS service level of 1; each PDN connection can contain one or more EPS bearers (i.e., evolved packet system bearers), and each EPS bearer can support a QoS, for example, a voice service is an EPS bearer with an EPS bearer service level of 1. Among them, the QoS flow of 5G and the EPS bearer of 4G correspond to each other.

[0058] 4-5, the MME sends a create session request to the SGW for creating a corresponding transmission tunnel for the EPS bearer.

[0059] 6, the MME sends a handover request to the 4G base station E-UTRAN, and carries the parameter information of the to-be-established EPS bearer in the handover request.

[0060] 7, the E-UTRAN allocates radio resources and transmission tunnel resources for the to-be-established EPS bearer and sends them to the MME. The radio resources include random access resources and data channel bearer (Data Radio Bearer, DRB) resources, and each EPS bearer corresponds to a DRB.

[0061] 8, the MME sends the transmission tunnel resources to the SGW to establish a transmission tunnel between the E-UTRAN and the SGW.

[0062] 9, the MME sends the radio resources allocated by the E-UTRAN for the user to the AMF.

[0063] 10, if the data cached by the terminal in the NG RAN has a high priority, the AMF informs the SMF+PGW-C to establish a forwarding tunnel for forwarding the data of the terminal from the NG RAN to the E-UTRAN.

[0064] 11, the AMF sends the radio resources allocated by the E-UTRAN for the user to the NG-RAN, and the NG RAN sends them to the terminal.

[0065] 12, the terminal accesses the E-UTRAN according to the radio resources allocated by the E-UTRAN, and replies a handover complete message.

[0066] In this way, the terminal can realize switching from the 5G network to the 4G network.

[0067] However, the above switching procedure can only realize the terminal switching from the 5G network to the 4G network, and after the switching, the terminal will re-register in the 4G network and release the registration of the original 5G network. That is, the terminal can only access the single network in the connected state and can only realize data transmission in the single network. However, there can be some terminals with strong capabilities, which support simultaneous dual-receiving and dual-transmitting data or support time-division multiplexing dual-receiving and dual-transmitting. For these terminals with enhanced capabilities, if the terminal is limited to connect to the single network (i.e., access the single network in the connected state) according to the related art, the capability of the terminal is wasted and the capability of the terminal is not fully utilized.

[0068] To solve the above problem, the embodiment of the present application provides a transmission processing method, device, terminal and network side equipment. The transmission processing method provided by the embodiment of the present application can be applied to the scenario of performing dual-network data transmission for a terminal.

[0069] In the transmission processing method provided by the embodiment of the present application, the first core network device receives a first message, the first message is used to request or trigger performing dual-network data transmission for a terminal, and the first core network device is a device in a first network where the terminal is located. The first core network device sends a second message to a first access network device, the second message is used to indicate an operation of performing dual-network data transmission for the terminal, and the operation includes an operation of enabling the terminal to perform dual-network data transmission in the connected state in the first network and a second network. The standard of the second network is different from or the same as the standard of the first network. Through the scheme, after the first core network device receives the first message used to request or trigger performing dual-network data transmission for the terminal, the first core network device can send the second message to the first access network device to indicate the operation of performing dual-network data transmission for the terminal. Therefore, the terminal can perform dual-network data transmission in the connected state in the first network and the second network. Therefore, for the terminal supporting dual-receiving and dual-transmitting data in hardware, the utilization efficiency of the terminal capability can be improved, and the waste of the terminal capability can be avoided.

[0070] The network architecture to which the transmission processing method provided by some embodiments of the present application is applied is exemplarily described below.

[0071] Exemplarily, as shown in FIG. 2, in order to interwork, the 6G network and the 5G network are provided with some network element functions, such as an SMF (interworking SMF, IWK SMF), an UPF (interworking UPF, IWK UPF), and the like, for jointly processing the terminal in the 6G session and the 5G session and maintaining IP address continuity. Among them, the IWK SMF contains the session context of the terminal in the two networks, and the SMF has the capability to map the 5G session context of the terminal from the 6G session context of the terminal or vice versa. In order to ensure successful handover, the network architecture shown in FIG. 2 can also assume that there is an interworking interface between the 6G AMF and the 5G AMF for delivering user context and the like. It should be noted that the 6G core network is replaced by the 6G AMF, and the 5G core network is replaced by the 5G AMF; in some scenarios, the 6G AMF and the 5G AMF can also be combined, for example, in the scenario of evolving the 6G core network and the 5G core network, they can be combined, and at this time, there is no interface between them.

[0081] Optionally, in embodiments of the present application, the double-sided data transmission can be replaced by the following meanings: the terminal accesses double-sided cells + core network, and the terminal is in a connected state in the double-sided network.

[0082] Optionally, in embodiments of the present application, the double-sided data transmission can also be referred to as dual steering (DS) data transmission.

[0273] In the embodiments of the present application, the second core network device can send the fourth message to the first core network device only in a case where the first condition is met, so that the fourth message can be sent to the first core network device only in a case where the terminal requires bilateral data transmission, to trigger the operation of performing bilateral data transmission for the terminal, thereby improving the accuracy of triggering the operation of performing bilateral data transmission for the terminal, and avoiding unnecessary triggering.

[0274] Optionally, the first condition includes that the terminal is in the first network, and initiates or is initiated with the second service requiring bilateral data transmission. The transmission processing method provided by the embodiments of the present application can further include the following steps 504 to 506.

[0275] The step 504, the second core network device sends a bearer request message to the first access network device for the second service.

[0276] The bearer request message is used to request bearer establishment or modification.

[0277] Optionally, the bearer can also be referred to as a QoS flow or a service flow tunnel, etc.

[0278] Step 505, the second core network device receives the bearer rejection message sent by the first access network device.

[0279] The bearer rejection message is used to reject bearer establishment or modification, and includes seventh indication information, which is used to indicate that the first access network device cannot establish or modify the bearer for the second service due to any of the following reasons: insufficient resources of the first network, insufficient wireless resources of the first network, and insufficient bandwidth resources of the first network.

[0280] Step 506, the second core network device determines that the first condition is met according to the seventh indication information.

[0281] In the embodiments of the present application, the second core network can determine that the first condition is met through the seventh indication information in the bearer rejection message sent by the first access network device, so as to send the fourth message to the first core network device to trigger the operation of performing bilateral data transmission for the terminal, and therefore the accuracy of triggering the operation of performing bilateral data transmission for the terminal can be further improved according to the resource situation of the first network.

[0282] The transmission processing method provided by the embodiments of the present application will be described exemplarily in combination with the accompanying drawings.

[0283] Exemplarily, taking the first core network device 6G AMF and the second core network device 6G SMF as an example, as shown in FIG. 6, the transmission processing method provided by the embodiments of the present application includes the following steps:

[0284] 1. A user equipment (User Equipment, UE) completes a registration process in a 6G network (i.e., the first network). Optionally, the UE also registers in the IMS system through the 6G network, which is used for subsequent calling or called IMS services of the UE, such as voice, data transmission or short message, etc.

[0285] 2. The 6G SMF sends a fourth message to the 6G AMF to trigger the UE to perform bilateral data transmission. The fourth message contains at least one of the following information:

[0286] Second indication information, which is used to indicate triggering bilateral data transmission;

[0287] Data volume information, used to indicate a data volume to be transmitted by the UE, for example, a data volume of a current UE granularity, a data volume of a session granularity, or a data volume of a bearer granularity, and the like.

[0288] Service information, used to indicate a specific service initiated or initiated by the UE, for example, a voice service or an XR service, and the like.

[0289] Optionally, the triggering condition for the 6G SMF to send the fourth message described above can be any of the following:

[0290] The UE is in the 6G network, and initiates or initiates a first service that needs to perform data transmission in the 5G network;

[0291] The UE is in the 6G network, and initiates or initiates a second service that needs to perform bilateral data transmission;

[0292] The data volume to be transmitted by the UE in the 6G network reaches a data volume threshold.

[0293] 3. The 6G AMF decides to initiate the operation of performing bilateral data transmission for the UE according to the fourth message described above, and performs the following steps.

[0294] Before that, optionally, the 6G AMF can also determine that the operation of bilateral data transmission for the UE is feasible. If the operation of bilateral data transmission for the UE is not feasible, the 6G AMF does not perform the subsequent steps.

[0295] 4. The 6G AMF sends a second message to the 6G RAN (i.e., the first access network device) to indicate the operation of performing bilateral data transmission for the UE.

[0296] Before performing step 4, optionally, the 6G AMF needs to determine that the operation of bilateral data transmission for the UE is feasible. If the operation of bilateral data transmission for the UE is not feasible, the 6G AMF does not perform step 4.

[0297] In an implementation manner, the second message described above can be a UE context setup or modification message. The second message contains at least one of the following information:

[0298] First request information, used to request bilateral data transmission;

[0299] First indication information, used to indicate that the operation of bilateral data transmission for the UE is feasible;

[0302] UE's bilateral data transmission capability information;

[0303] UE's terminal type information.

[0304] The above content in step 4 can be sent to the 6G RAN through a second message, or sent to the 6G RAN through different messages, as in step 5a.

[0305] Step 5a, optionally, the 6G RAN sends a capability information request message to the 6G AMF to request the first capability information.

[0306] The above first capability information includes at least one of the following:

[0307] Whether the operation of the UE's bilateral data transmission is feasible;

[0308] Whether the UE supports bilateral data transmission;

[0309] Whether the network supports bilateral data transmission;

[0310] Spectrum combination information of the UE's bilateral data transmission.

[0311] This step generally occurs when the 6G AMF does not inform the 6G RAN of the above first indication information and the UE's bilateral data transmission capability information in step 4.

[0312] Step 5b, optionally, the 6G RAN obtains the second capability information from the UE through the air interface.

[0313] The second capability information includes at least one of the following:

[0314] Whether the UE supports bilateral data transmission;

[0315] Spectrum combination information of the UE's bilateral data transmission;

[0316] UE's terminal type information.

[0317] Steps 6-7: The 6G RAN triggers the switching UE access 5G cell procedure according to the second message, and the 6G RAN sends a handover request message to the 6G AMF.

[0318] Optionally, before the 6G RAN initiates step 7, the following condition needs to be met: the operation of the UE's bilateral data transmission is feasible.

[0319] Optionally, before step 7, the 6G RAN can also select a target cell according to the spectrum combination information of the UE's bilateral data transmission, wherein the UE supports bilateral data transmission on the cell it is in and the target cell.

[0320] Among them, on the basis of the original handover request message content, the above-mentioned handover request message further contains at least one of the following:

[0321] Second reason indication information, the second reason indication information is used to indicate the reason for switching of the UE's bilateral data transmission;

[0322] Third indication information, the third indication information is used to indicate that the UE supports bilateral data transmission on the cell and the target cell;

[0323] The bearer identity of the bearer to be switched.

[0324] 8. According to the handover request message, the 6G AMF sends a context request message to the 6G SMF to obtain the context information of the 5G session of the UE in the SMF.

[0325] It should be noted that the 6G SMF can be an SMF responsible for 6G and 5G interworking, and can be a network element deployed by 6G network and 5G network, and there are 6G session context and 5G session context of the UE on it.

[0326] Specifically, the above-mentioned context request message contains at least one of the following information:

[0330] First operation information, the first operation information is used to indicate the processing operation corresponding to the first object, and the first object is the session or bearer corresponding to the UE.

[0331] 8a. Optionally, before step 8, the 6G AMF determines the above-mentioned first operation information. The specific determination method includes:

[0332] According to the processing request and / or operation tendency corresponding to the session or bearer sent by the UE. Or, according to the local configuration information, the operator policy information is determined; At this time, it is assumed that the operator policy configures some information indicating that when the UE is in the bilateral data transmission mode: which service can be bilateral data transmission, which service is reserved in 6G single transmission, and which service is switched to 5G single transmission. For example, XR service can be transmitted by 6G and 5G, data service can be transmitted by 6G single side, and voice service can be transmitted by 5G single side.

[0333] It should be noted that in the above bilateral data transmission mode, the UE can be in any of the following states: (1) the UE retains the 6G registration, but all services are switched to 5G (i.e. switching); (2) some services are in 6G and some services are in 5G (i.e. steering); (3) the same service exists in 5G and 6G (i.e. splitting).

[0334] 9. The 6G SMF sends a reply message to the 6G AMF, which contains the UE session context to be switched to 5G.

[0335] Optionally, the reply message further contains the first operation information. This information is determined by the 6G SMF, and specifically the 6G SMF determines it according to the first operation information sent by the 6G AMF in step 8 or the 6G AMF local configuration information. When the 6G SMF determines this information according to the first operation information sent by the 6G AMF in step 8, the two may be the same or different, indicating the first operation information allowed by the 6G SMF requested by the 6G AMF.

[0336] 10a. The 6G AMF initiates a migration request message to the 5G AMF to request network resources reserved for the UE in the 5G network.

[0337] Optionally, on the basis of the original handover process, the migration request message can additionally carry:

[0338] Fourth reason indication information, which is used to indicate the reason for sending the migration request message as the bilateral data transmission of the UE;

[0339] Sixth indication information, which is used to indicate the bilateral data transmission.

[0340] The following steps are other procedures of the handover preparation process, which can be referred to the specific description in the related art:

[0341] 10b. The 5G AMF initiates a handover request message to the 5G RAN and receives a handover request confirmation message sent by the 5G RAN.

[0342] 10c. The 5G AMF sends a migration response message to the 6G AMF.

[0343] 10d. The 6G AMF sends a handover command to the 6G RAN.

[0344] 10e. The 6G RAN sends a handover command to the UE.

[0345] 11. The 5G AMF sends a session update message to the SMF, which carries the 5G RAN information (address, tunnel endpoint, etc.) as the downlink address of the data transmission. The message also carries the session and bearer information accepted by the 5G RAN for handover. The SMF performs processing operations according to the aforementioned first operation information.

[0346] At this point, the handover preparation procedure ends, and the UE receives the handover command sent by the 6G RAN, i.e., the handover execution procedure for accessing the 5G cell will be performed.

[0372] Optionally, in the embodiment of the present application, the second condition includes that the terminal is in the first network, and initiates or is initiated to perform the second service requiring bilateral data transmission. Exemplarily, the transmission processing method provided by the embodiment of the present application can further include the following steps 702 to 704.

[0373] Step 702, the terminal sends a bearer request message in the first network for the second service.

[0374] The bearer request message is used to request bearer establishment or modification.

[0375] Step 703, the terminal receives a bearer rejection message.

[0376] The bearer rejection message is used to reject the establishment or modification of a bearer, and the bearer rejection message includes eighth indication information, which is used to indicate that the first network is unable to establish or modify a bearer for the second service because the first network is out of resources.

Optionally, the UE also registers in the IMS system through the 6G network, which is used for the UE to subsequently perform the calling or called IMS service, such as voice, data transmission or short message, etc.

[0381] 2. When the UE initiates the MO voice service according to the user request (such as obtaining the user key operation), or the UE is called by other terminals to perform the MT voice service (such as receiving the SIP invite message), the UE decides to initiate the execution of the bilateral data transmission request.

[0382] Optionally, the UE also needs to determine that at least one of the following conditions is established before initiating the execution of the bilateral data transmission request:

[0383] The UE is in the 6G network, and initiates or is initiated to perform the first service which needs to perform data transmission in the 5G network;

[0387] The UE detects that there is a second cell of the 5G network, and the UE supports performing bilateral data transmission on the second cell and the first cell of the 6G network.

[0388] 3. The UE sends a third message to the 6G AMF to request the execution of bilateral data transmission for the UE.

[0389] In one approach, the third message can be a NAS message. The third message carries at least one of the following fields:

[0390] Second request information, the second request information is used to request to perform bilateral data transmission;

[0391] First reason indication information, the first reason indication information is used to indicate the reason why the UE requests to perform bilateral data transmission;

[0392] Spectrum combination information of the UE supporting bilateral data transmission;

[0393] UE processing request corresponding to the session or bearer;

[0394] UE operation preference corresponding to the session or bearer.

[0395] 4-11, same as step 4-11 in the example of FIG. 6.

[0396] So far, the handover preparation procedure ends, and the UE receives the handover command sent by the 6G RAN, i.e., the handover execution procedure of accessing the 5G cell will be performed.

[0397] Other descriptions of the transmission processing method provided by the embodiments of the present application can be referred to the related descriptions in the above-mentioned first core network side method embodiment, the above-mentioned first access network device side method embodiment and the above-mentioned second core network device method embodiment. To avoid repetition, it will not be described here.

[0398] Exemplarily, after the handover preparation procedure in the above-mentioned examples of FIG. 6 or FIG. 8, the UE and the network initiate the handover execution procedure, which can refer to the handover procedure in the related art. For example, as shown in FIG. 9, the specific procedure is as follows:

[0399] 1, the UE accesses the 5G cell, and initiates a handover completion message to the 5G RAN;

[0400] 2, the 5G RAN initiates a handover notification HO notify to the 5G AMF, informing the 5G AMF that the UE has accessed the cell;

[0401] 3a-3b, the 5G AMF interacts with the 6G AMF to inform that the UE accesses the 5G cell;

[0402] 4, the 5G AMF sends a bearer modification message to the SMF, which contains session handover success confirmation information. In addition to the above-mentioned traditional information, the first operation information is optionally carried in the message.

[0403] 5, the SMF performs operation according to the first operation information.

[0404] After the UE switches to the 5G network, one of the following two situations may occur:

[0405] 7a、Optionally, the UE suppresses 5G registration due to the occurrence of bilateral data transmission, that is, the UE does not initiate a re-registration process in the 5G network, so that the UE accesses the 6G and 5G bilateral cells, but only maintains one-side registration.

[0406] 7b、Optionally, if the UE initiates a registration process in the 5G network, the 5G AMF sends a UE location update message to the UDM for updating the UE registration information. The location update message contains indication information for indicating to the UDM that the UE has bilateral data transmission, or directly for informing the UDM not to delete the 6G registration information of the UE (because the UE has bilateral data transmission).

[0407] It should be noted that in the embodiments of the present application, the first network is taken as the 6G network, and the second network is taken as the 5G network for example, and in actual implementation, the first network can be the 5G network, and the second network can be the 6G network, or the first network and the second network are both 6G networks, and the like, which are not limited in the embodiments of the present application.

The frequency band information of the cell can be acquired by the first core network device through the configuration information or from the corresponding base station.

[0423] Optionally, in the embodiments of the present application, when all the information in the first information is true, the first core network device can determine that the operation of the bilateral data transmission of the terminal is feasible; at this time, it indicates that the terminal subscribes to the bilateral data transmission service, and both the terminal and the network support the bilateral data transmission service.

[0430] The subscription information includes bilateral data transmission subscription information of the terminal.

[0431] Optionally, in the embodiments of the present application, the fourth core network device can be used for unified data management; for example, the fourth core network device can be a UDM.

[0432] The specific method for the first core network device to determine whether the operation of bilateral data transmission for the terminal is feasible will be described exemplarily in combination with the accompanying drawings.

[0433] Exemplarily, taking the first core network device as a 6G AMF and the fourth core network device as a UDM as an example, as shown in FIG. 10, the specific process in which the first core network device determines whether the operation of bilateral data transmission for the terminal is feasible is as follows:

[0440] Frequency band combination information of the cell currently occupied by the terminal and the surrounding neighbor cell.

[0441] In an implementation manner, the 6G AMF needs to determine that the above four conditions are established at the same time, and then it is determined that the operation of bilateral data transmission for the terminal is feasible. At this time, it is indicated that the terminal subscribes to the bilateral data transmission service, and both the terminal and the network support the bilateral data transmission service. In other implementation manners, the AMF can also determine that one or more conditions are established, and then it is determined that the operation of bilateral data transmission for the terminal is feasible.

[0442] 4. The 6G AMF sends second information to the RAN, to indicate whether the operation of bilateral data transmission for the terminal is feasible.

[0443] Specifically, the 6G AMF can send the second information to the RAN by initiating a terminal context setup message, a terminal context modification message to the RAN, or by the side when the AMF sends a DL NAS message to the terminal. The second information is used for the RAN to subsequently determine whether the terminal and the network support the bilateral data transmission service, so as to decide whether to trigger switching, redirection and other operations to initiate the bilateral data transmission service.

[0449] The first receiving module 111 can receive a first message. The first message is used to request or trigger the terminal to perform the bilateral data transmission. The first sending module 112 can send a second message to the first access network device. The second message is used to indicate an operation of performing the bilateral data transmission for the terminal.
