[0030] Figure 1 In the schematic diagram of the wireless communication system protocol stack architecture shown, the wireless communication system includes a terminal-side device and an access network-side device, and optionally further includes a core network-side device.

[0031] The terminal-side device can be an independently sold terminal or a chip system in the terminal. Among them, the terminal is also called user equipment (UE) or mobile station, and includes mobile phones, handheld Internet of Things devices, wearable devices, etc.

[0032] The access network-side device can be an independently sold base station or a chip system for implementing base station functions. Among them, the base station can be divided into two major categories: macro base stations and small base stations, and small base stations are further divided into micro base stations, pico base stations, etc.

[0033] Data is transmitted between the terminal-side device and the base station by establishing at least one radio bearer (RB). Among them, the data can include signaling data or service data. The radio bearer mainly used for transmitting signaling data is the signaling radio bearer (SRB), and the radio bearer mainly used for transmitting service data is the data radio bearer (DRB). The service data includes enhanced mobile broadband (eMBB) data, massive machine type communication (mMTC) data, ultra reliable and low latency communication (URLLC) data, etc.

[0034] As Figure 1 shown, the access network-side device 2 can be directly connected to the core network-side device by a wired method, or can be first connected to the access network-side device 1 by a wired method, and then relayed by the access network-side device 1 to indirectly connect the access network-side device 2 to the core network-side device. The terminal-side device 1 can be served by both the access network-side device 1 and the access network-side device 2 simultaneously through dual connectivity technology. Among them, one of the access network-side device 1 and the access network-side device 2 serves as the primary base station of the terminal-side device, and the other serves as the secondary base station of the terminal-side device. The primary base station corresponds to the master cell group (MCG), and the secondary base station corresponds to the secondary cell group (SCG).

[0035] Under the evolved terrestrial radio access - new radio dual connectivity (EN-DC) architecture, the core network side device is the evolved packet core network (EPC), the access network side device 1 is the long-term evolution (LTE) base station acting as the master base station, and the access network side device 2 is the new radio (NR) base station (i.e., 5G base station) acting as the secondary base station. Under this architecture, the interface between the LTE base station and the NR base station is the X2 interface, including a control plane connection and optionally also including a user plane connection; the interface between the LTE base station and the EPC is the S1 interface, including a control plane connection and optionally also including a user plane connection; the interface between the NR base station and the EPC is the S1-U interface, including only the user plane connection.

[0036] Under the new radio - evolved terrestrial radio access dual connectivity (NE-DC) architecture, the core network side device is the 5G core network device, the access network side device 1 is the NR base station acting as the master base station, and the access network side device 2 is the LTE base station acting as the secondary base station. Under this architecture, the interface between the LTE base station and the NR base station is the X2 interface, including a control plane connection and optionally also including a user plane connection; the interface between the NR base station and the 5G core network device is the NG interface, including a control plane connection and optionally also including a user plane connection; the interface between the LTE base station and the 5G core network device is the NG-U interface, including only the user plane connection.

[0037] Under the next-generation radio access node evolved terrestrial radio access - new air interface dual connectivity (NGEN-DC) architecture, the core network side device is the 5G core network device, the access network side device 1 is the LTE base station acting as the master base station, and the access network side device 2 is the NR base station acting as the secondary base station. Under this architecture, the interface between the LTE base station and the NR base station is the Xn interface, including a control plane connection and optionally also including a user plane connection; the interface between the LTE base station and the 5G core network device is the NG-U interface, including a control plane connection and optionally also including a user plane connection; the interface between the NR base station and the 5G core network device includes only the user plane connection.

[0038] In the scenario of new radio dual connectivity (NR-DC), the core network side device is the 5G core network device, and the access network side device 1 and the access network side device 2 are the NR master base station and the NR secondary base station respectively; the interface between the NR base stations is the Xn interface, including a control plane connection and optionally also including a user plane connection; the interface between the NR master base station and the 5G core network device is the NG interface, including a control plane connection and optionally also including a user plane connection; the interface between the NR secondary base station and the 5G core network device is the NG-U interface, including only the user plane connection.

[0039] In a wireless communication system, the terminal-side device is configured with a corresponding software version number (SVN) by the manufacturer during manufacturing, where the software version number indicates the software version information currently used by the terminal-side device. When the terminal-side device is in the process of starting up to establishing a connection with the core network-side device, it carries the SVN in the International Mobile station Equipment Identity and Software Version Number (IMEISV), and notifies the core network-side device through the non-access stratum (NAS). Generally, the IMEISV is 16 bits and includes three components: an 8-bit type allocation code (TAC), a 6-bit serial number (SNR), and a 2-bit SVN. The core network-side device can set the last 4 bits of the SVR in the IMEISV to 1 to generate a masked IMEISV, and then send the masked IMEISV to the access network-side device serving the terminal-side device.

[0040] The access network-side device generates corresponding configurations for the terminal according to the masked IMEISV to ensure that the network service can be compatible with the software version of the terminal-side device. However, in the dual-connection scenario or during the implementation of dual-connection, since the terminal-side device is served by at least two access network-side devices simultaneously, the configurations of the at least two access network-side devices for the terminal-side device may be incompatible, reducing the data transmission efficiency.

[0041] In view of this problem, the first embodiment of this application provides a communication processing method for terminal information, which is applied to the scenario of adding a secondary base station to implement dual-connection of the terminal-side device, as Figure 2 shown, including the following content.

[0042] S201, the first access network-side device sends a secondary base station addition request message to the second access network-side device, and the secondary base station addition request message contains the software version information of the terminal-side device.

[0043] S202, the first access network-side device receives the secondary base station addition confirmation message sent by the second access network-side device, and the secondary base station addition confirmation message contains the configuration determined based on the software version information.

[0044] Optionally, the software version information of the terminal is IMEISV or masked IMEISV.

[0045] In 201, the first access network device may determine whether to add the second access network device as a secondary base station for the terminal device to implement dual connectivity for the terminal side. If it is determined to add the secondary base station, the first access network device sends a secondary base station addition request message to the second access network device.

[0046] In 202, the second access network device may determine whether it can implement dual connectivity for the terminal device according to the received secondary base station addition request message. If so, the second access network device identifies the way for the terminal device to implement various technical features according to the software version information of the terminal device, and then generates corresponding configurations for the terminal device. The second access network device then carries the configurations in a secondary base station addition confirmation message and sends it to the first access network device. The "technical features" in various embodiments of this application may refer to various capabilities supported by the terminal device, such as whether it supports device to device connection, whether it supports minimized drive test (MDT), whether it supports the ability to provide relay services for other terminal devices to the network device, whether it supports carrier aggregation, etc. The access network device may generate corresponding configurations according to different technical features.

[0047] S203, the first access network device sends the configurations generated by the second access network device to the terminal device, or the first access network device generates new configurations after referring to the configurations and sends them to the terminal device.

[0048] Optionally, the secondary base station addition request message may include the TDM pattern configuration determined by the first access network device. The second access network device may determine the proposed TDM pattern configuration according to the received TDM pattern configuration, and carry it in the secondary base station addition request message and send it to the first access network device, so that the first access network device forwards it to the terminal device, or generates a new TDM pattern configuration after referring to the proposed TDM pattern configuration and sends it to the terminal device. Among them, the TDM pattern indicates the time period for data transmission with the first access network device and the time period for data transmission with the second access network device.

[0049] After dual connectivity is completed, the first access network device serves as the master base station, and the second access network device serves as the secondary base station, jointly providing services for the terminal device. The terminal device may perform data transmission with the master base station and the secondary base station according to the configurations, and optionally, also including the TDM pattern configuration received from the first access network device.

[0050] Applying the technical solution provided by the first embodiment of the present application, in dual connectivity, the secondary base station participates in generating relevant configurations corresponding to the terminal software version information, which can reduce the occurrence of incompatibility problems between access network side devices with respect to the terminal side device, thereby improving the data transmission efficiency.

[0051] In a dual connectivity scenario, the terminal side device can perform data transmission with a first access network side device and a second access network side device. However, as the terminal side device moves, the primary base station may switch from the first access network side device to another access network side device (assumed to be a third access network side device). After the switch, the terminal side device may still use the configuration before the switch for data transmission, resulting in a reduction in data transmission efficiency after the switch, which is more obvious especially for configurations such as TDM pattern configuration or uplink power configuration.

[0052] In view of the above technical problems, the second embodiment of the present application provides a communication processing method for terminal information, which is applied to a dual connectivity scenario, as Figure 3 shown, and includes the following. In the dual connectivity scenario, the first access network side device is the primary base station of the terminal side device, the second access network side device is the secondary base station of the terminal side device, and the third access network side device is the target base station to which the terminal side device is to be switched.

[0053] S301, the first access network side device sends a handover request to the third access network side device.

[0054] Optionally, the handover request includes a first configuration or an indication of whether the first configuration exists, where the first configuration includes at least one of: the first time division multiplexing pattern (TDM pattern) configuration when the terminal side device is served by the first access network side device (i.e., before the handover), and the first uplink power configuration.

[0055] The first TDM pattern is used to indicate the time when the terminal side device configured with dual connectivity can perform uplink transmission at the source base station and the source secondary base station respectively. The first uplink power configuration indicates the maximum power for the terminal side device to perform uplink transmission on the primary base station or the secondary base station.

[0056] S302, the third access network side device sends a handover request confirmation to the first access network side device.

[0057] Optionally, the handover request confirmation includes a second configuration, where the second configuration includes one or a combination of the following:

[0058] The second TDM pattern configuration when the terminal-side device is served by the third access network side device (i.e., after handover is completed); the second uplink power configuration when the terminal-side device is served by the third access network side device (after handover is completed) (the second uplink power configuration indicates the maximum power for the terminal-side device to perform uplink transmission on the target base station.); information indicating the release or retention of the first configuration.

[0059] Optionally, the third access network side device can be used as the target master base station to determine to add a target secondary base station for the terminal-side device during the handover process (as shown in Figure 4 ), or change the secondary base station for the terminal-side device during the handover process (i.e., the source secondary base station is changed to the target secondary base station, as shown in Figure 5 ), so as to achieve dual connectivity after handover. The third access network device can configure the second TDM pattern. The second TDM pattern indicates the time for the terminal-side device to perform uplink transmission on the target master base station and the target secondary base station respectively. Optionally, the target secondary base station can be the source secondary base station. In this case, during the handover process, the source secondary base station remains unchanged as the secondary base station of the terminal-side device before and after handover.

[0060] Optionally, the second access network side device acting as the secondary base station remains unchanged before, during, and after handover.

[0061] Optionally, when the second configuration includes the second TDM pattern configuration, the second configuration further includes the effective time of the second TDM pattern configuration. The first access network side device can forward the second configuration to the terminal-side device, and the terminal-side device can make the second TDM pattern configuration effective at the effective time and communicate with the third access network side device according to the second TDM pattern configuration. Optionally, as another implementation, the second configuration can include the timing duration of a timer specific to the second TDM pattern configuration, and after the timer expires, the terminal-side device makes the second TDM pattern configuration effective.

[0062] The effective time can be after the terminal-side device accesses the third access network side device through a random access process (i.e., after S304 is completed), or after sending a random access request during the random access process. Among them, the random access request can be a random access preamble or a demodulation reference signal DMRS. In this implementation manner, the terminal-side device performing a random access process or sending a random access request is not restricted by the TDM pattern configuration.

[0063] Optionally, in 302, the third access network side device determines to configure dual connectivity after the terminal side device switches, and whether there may be interference or power sharing issues. If dual connectivity is not configured, or if dual connectivity is configured but there is no interference, or if dual connectivity is configured but there is no power sharing issue, the second configuration indicates releasing the first configuration. If so, the second configuration contains information indicating to retain the first configuration, the second TDM pattern configuration or the second uplink power configuration.

[0064] Optionally, when the handover request includes the first configuration, the third access network side device may determine the second configuration according to the first configuration. When the handover request includes an indication of whether the first configuration exists, the third access network side device may determine the second configuration by itself. If the third access network side device determines that the second TDM pattern configuration or the second uplink power configuration needs to be configured, the second configuration contains the second TDM pattern configuration or the second uplink power configuration. If not, the second configuration contains information indicating to release the first configuration.

[0065] Optionally, when the handover request does not include the first configuration, the third access network side device determines the second configuration by itself. For example, if the third access network side device determines that a TDM pattern does not need to be configured, the second configuration contains an indication to release the first configuration; if it is needed, the second configuration contains the second TDM pattern configuration or the uplink power configuration.

[0066] S303, the source base station sends a handover command to the terminal side device. Optionally, the handover command contains the second configuration.

[0067] S304, the terminal side device accesses the third access network side device through a random access procedure.

[0068] In 304, when the handover command contains the second configuration, the terminal side device may communicate with the third access network side device according to the second configuration during or after the random access procedure. When the handover command does not include the second configuration, the terminal side device defaults to releasing the first configuration.

[0069] Applying the technical solution provided by the second embodiment, the terminal side device and the third access network side device can maintain consistent configurations, avoiding a reduction in communication efficiency with the target base station caused by the terminal side device using an inappropriate configuration.
