[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application.

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0027] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the above-mentioned systems and radio technologies as well as for other systems and radio technologies. The following description describes a new radio (NR) system for example purposes, and NR terms are used in most of the following descriptions, but these technologies can also be applied to applications other than NR system applications, such as the 6th Generation (6G) communication system.

[0028] Figure 1 A block diagram of a wireless communication system applicable to the embodiment of the present application is shown. The wireless communication system includes a terminal 11 and a network device 12. Among them, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), a RedCap UE and other terminal-side devices, wherein the RedCap UE) may include: wearable devices, industrial sensors, video surveillance equipment, etc., and the wearable devices include: bracelets, headphones, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

[0029] The network device 12 can be a base station or a core network, wherein the base station can be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (Transmitting Receiving Point, TRP) or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0030] In addition, in the embodiments of the present application, it can be applied to scenarios supporting broadcast / multicast features, such as: public safety and mission critical, V2X applications, transparent IPv4 / IPv6 multicast delivery, IPTV, software delivery over wireless, group communications and IoT applications, etc., which support broadcast / multicast features. Of course, the embodiments of the present application are not limited to this, for example, other unicast scenarios are also possible.

[0031] In the embodiment of the present application, SL communication may include broadcast, groupcast, and unicast transmission forms. Among them, unicast is a one-to-one transmission as the name implies. Multicast is a one-to-many transmission. Broadcast is also a one-to-many transmission, but broadcast does not have the concept of terminals belonging to the same group. In addition, the resource allocation mode of SL communication may include a network device scheduling mode and a terminal autonomous mode.

[0032] In the embodiment of the present application, the terminal supports the aggregation of SL communication and non-3GPP short-distance communication, taking WLAN communication as an example of non-3GPP short-distance communication. In the way of aggregation of SL communication and WLAN communication, a part of the data flow in the SL communication architecture can be diverted to WLAN for transmission, and unified management and control are performed. In the architecture of SL and WLAN aggregation, the following three types of bearers can be included:

[0033] SL bearer: refers to a bearer that is transmitted entirely through SL interfaces and resources. This bearer can be either a user data bearer or a signaling bearer.

[0034] WLAN Split Bearer: refers to a bearer that is transmitted through both the SL interface and resources and the WLAN interface and resources. This bearer can be either a user data bearer or a signaling bearer.

[0035] A switched WLAN bearer refers to a bearer that is transmitted entirely through WLAN interfaces and resources. This bearer can be either a user data bearer or a signaling bearer; however, in general, it is mainly used for user data bearer.

[0036] like Figure 2 As shown, Figure 2 Taking user plane (UP) data as an example, a schematic diagram of the protocol stack architecture of SL and WLAN aggregation is given. In the protocol stack architecture, the service data adaptation protocol (SDAP) of the sending terminal and the receiving terminal corresponds to the SL bearer, the WLAN fork bearer and the switched WLAN bearer, wherein the data of the SL bearer and the WLAN fork bearer of the sending terminal can be sent to the SL bearer and the WLAN fork bearer corresponding to the receiving terminal, and the data of the switched WLAN bearer of the sending terminal can be sent to the switched WLAN bearer corresponding to the receiving end.

[0037] The auxiliary information acquisition method, configuration method, terminal and network device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0038] See also Figure 3 , Figure 3 is a flowchart of a method for obtaining auxiliary information provided by an embodiment of the present application, the method being executed by a terminal, such as Figure 3 As shown, the following steps are included:

[0039] Step 301: Acquire routing rule auxiliary information, where the routing rule auxiliary information is used by the terminal to perform path switching or path selection.

[0040] The above-mentioned acquisition of routing rule auxiliary information acquires pre-configured routing rule auxiliary information, or receives routing rule auxiliary information dynamically configured by a network device, etc., which is not specifically limited. For example, the above-mentioned routing rule auxiliary information can be configured to the terminal based on the policy configuration process of a policy control function (PCF).

[0041] The above-mentioned path may be a communication mode, for example: SL communication, non-3GPP short-distance communication. The above-mentioned path switching may be switching from the currently used path to other paths, for example: the terminal is currently using SL communication, and switches to the aggregated communication of SL communication and non-3GPP short-distance communication according to the above-mentioned routing rule auxiliary information. The above-mentioned path selection may be selecting a path from multiple paths, for example: selecting one communication from SL communication, non-3GPP short-distance communication, or the aggregated communication of SL communication and non-3GPP short-distance communication.

[0042] In addition, the above-mentioned path switching can be switching to a path corresponding to the service type or application according to the service type or application, and the above-mentioned path selection can be selecting a path corresponding to the service type or application according to the service type or application, thereby improving the terminal communication performance.

[0043] In the embodiment of the present application, the above steps can be used to obtain the above routing rule auxiliary information, so that path switching or path selection can be performed according to the routing rule auxiliary information, thereby improving the terminal communication performance.

[0044] As an optional implementation manner, the routing rule auxiliary information is a mapping relationship, the mapping relationship is a mapping relationship between a communication object and a communication mode, and the method further includes:

[0045] Determining a target communication mode of data of a target communication object according to the mapping relationship;

[0046] The mapping relationship includes at least one mapping relationship between a communication mode and a communication object:

[0047] SL communication;

[0048] Non-3GPP short-range communications;

[0049] SL communication and non-3GPP short-range communication;

[0050] Aggregate communication of SL communication and non-3GPP short-range communication;

[0051] Interoperable communication between SL communication and non-3GPP short-range communication.

[0052] The above-mentioned SL communication may be transmitted using only SL communication, and the above-mentioned non-3GPP short-distance communication may be transmitted using only non-3GPP short-distance communication, for example, using at least one of WLAN, WIFI and Bluetooth for transmission.

[0053] The above-mentioned SL communication and non-3GPP short-distance communication may be: the same service data will be transmitted in both SL communication and non-3GPP short-distance communication.

[0054] The above-mentioned aggregated communication of SL communication and non-3GPP short-distance communication can be: a part of the data flow in the SL architecture is diverted to the non-3GPP short-distance communication for transmission, and unified management and control are performed, that is, which part of the data is transmitted through SL communication and which part of the data is transmitted through non-3GPP short-distance. In this communication mode, SL communication and non-3GPP short-distance communication can transmit data at the same time.

[0055] The interoperable communication of the above-mentioned SL communication and non-3GPP short-distance communication can be: using SL communication at one time and using non-3GPP short-distance communication at another time. This communication method is similar to the aggregated communication of the above-mentioned SL communication and non-3GPP short-distance communication. The network needs to control the sending of SL communication and non-3GPP short-distance communication data streams, that is, when selecting the interoperable communication of SL communication and non-3GPP short-distance communication, the network needs to control when to use SL communication and when to use non-3GPP short-distance communication.

[0056] The above mapping relationship includes the communication objects passed by each of the above communication methods, such as the service type, application, network or access point corresponding to each communication method. Specifically, it can be a mapping relationship between the communication method and the service type identifier, application identifier, network name (Network Name), and access point name (Access Point Name, APN).

[0057] The target communication object may be a communication object that currently needs to perform data transmission. Specifically, the target communication object may include the following:

[0058] Target service type, target application identifier, target network, target access point.

[0059] In this implementation, the target communication mode of the target communication object's data is determined according to the above mapping relationship, so that the data of any communication object can be transmitted using the communication mode corresponding to the communication object, thereby improving the communication performance of the terminal.

[0060] As an optional implementation, the routing rule auxiliary information is a first enhanced user terminal routing selection policy (UE routing selection policy, URSP) rule, and the component extension of the routing selection descriptor of the first enhanced URSP rule includes a path selection component, and the path selection component includes a target communication mode, wherein the target communication mode includes at least one of SL communication and non-3GPP short-range communication.

[0061] The target communication mode includes at least one of SL communication and non-3GPP short-range communication. The target communication mode may include one of the following:

[0062] SL communication;

[0063] Non-3GPP short-range communications;

[0064] SL communication and non-3GPP short-range communication;

[0065] Aggregate communication of SL communication and non-3GPP short-range communication;

[0066] Interoperable communication between SL communication and non-3GPP short-range communication.

[0067] For example: when the terminal has service data to send, if the target communication mode mapped by the service type / application identifier of the service is non-3GPP short-distance communication, the non-3GPP short-distance communication mode will be selected, and the service data will be routed to the non-3GPP short-distance communication mode. Other methods, such as indicating the SL communication mode, are the same and will not be explained one by one here.

[0068] The above-mentioned path selection component is a component obtained by expanding the components of the routing descriptor of the first enhanced URSP rule defined in the protocol in the embodiment of the present application. For example, as shown in the following Table 1:

[0069] Table 1:

[0070]

[0071] It should be noted that, except for the path selection component in the above table, the relevant contents of other components can refer to the definition in the protocol, and will not be described in detail here. In addition, the path selection component in the embodiment of the present application can also be called a route selection component.

[0072] In this implementation, the target communication mode can be indicated by the above-mentioned path selection component, so as to execute path switching or path selection of the target communication mode to improve the terminal communication performance.

[0073] Optionally, the above method further includes:

[0074] When the path selection component includes the target communication mode and the service data of the terminal matches the service descriptor in the URSP rule, the service data is routed to the target communication mode for transmission.

[0075] The service descriptor in the URSP rule is used to indicate the communication object corresponding to the URSP, for example, the service type, application identifier, network, and access point applicable to the URSP rule. For example, when the terminal has service data to send, after applying the URSP rule, when the data matches the service descriptor in the URSP rule, and the path selection component in the selected routing descriptor indicates a non-3GPP short-distance communication mode, the non-3GPP short-distance communication mode is selected, and the service data will be routed to the non-3GPP short-distance communication mode.

[0076] In this implementation, when the service data of the terminal matches the service descriptor in the URSP rule, the service data can be routed to the target communication mode for transmission, thereby improving the communication performance of the terminal.

[0077] As an optional implementation, the routing rule auxiliary information is a second enhanced URSP rule, and the non-seamless offload indication (Non-Seamless Offload indication) component extension of the second enhanced URSP rule includes a target communication mode, wherein the target communication mode includes at least one of a side link SL communication and a non-3GPP short-distance communication.

[0078] The non-seamless offload indication component may be extended to include the target communication mode by adding the target communication mode to the non-seamless offload indication component. The non-seamless offload indication component may indicate the target communication mode, thereby executing path switching or path selection of the target communication mode to improve terminal communication performance.

[0079] Optionally, the above method further includes:

[0080] When the non-seamless offload indication component extension includes a target communication mode, and the service data of the terminal matches the service descriptor in the URSP rule, the service data is offloaded to the target communication mode for transmission.

[0081] The above-mentioned diverting the service data to the target communication mode for transmission may be that when the service data of the terminal matches the service descriptor in the URSP rule, the service data is diverted to the target communication mode when the above-mentioned rule is applied. For example: when the terminal has service data to send, when the service data matches the service descriptor in the URSP rule, and the extended non-seamless diversion indication component in the selected routing descriptor indicates an aggregated communication mode of SL communication and non-3GPP short-distance communication, the aggregated communication of SL communication and non-3GPP short-distance communication is selected, and the service data will be routed to the aggregated communication mode of SL communication and non-3GPP short-distance communication.

[0082] As an optional implementation, the routing rule auxiliary information is a third enhanced URSP rule, and the access type preference (Access Type Preference) component extension of the third enhanced URSP rule includes a target communication mode, wherein the target communication mode includes at least one of a secondary link SL communication and a non-3GPP short-range communication.

[0083] The access type preference extension including the target communication mode may be to add the target communication mode to the access type preference component. The access type preference component may indicate the target communication mode, thereby executing path switching or path selection of the target communication mode to improve the terminal communication performance.

[0084] Optionally, the method further includes:

[0085] When the access type preference component extension includes a target communication mode and the service data of the terminal matches the service descriptor in the URSP rule, the preferred access type of the protocol data unit (PDU) session established by the service data is determined as the target communication mode.

[0086] The above-mentioned determination of the preferred access type of the PDU session established by the service data as the target communication mode may be that when the service data of the terminal matches the service descriptor in the URSP rule, when the above-mentioned rule is applied, the preferred access type of the PDU session established by the service data is determined as the target communication mode, and the PDU session data is transmitted through the target communication mode. For example: when the terminal has service data to send, after the service data matches the service descriptor in the URSP rule, and the extended access preference component in the selected routing descriptor indicates a non-3GPP short-distance communication mode, non-3GPP short-distance communication is selected, and the preferred access type of the PDU session established by the service data is determined as the target communication mode, and the PDU session is transmitted through the non-3GPP short-distance communication.

[0087] As an optional implementation manner, the above mapping relationship is configured to the terminal as a terminal policy, and the terminal policy is configured to the terminal through a pre-configuration manner or a PCF-based policy configuration process.

[0088] The PCF-based policy configuration process may be configured for the terminal by configuring the mapping relationship for the terminal during a general configuration update process of the terminal.

[0089] As an optional implementation manner, at least one of the first enhanced URSP rule, the second enhanced URSP rule and the third enhanced URSP rule is configured to the terminal as a terminal policy, and the terminal policy is configured to the terminal through a pre-configuration manner or a PCF-based policy configuration process.

[0090] The PCF-based policy configuration process may be configured for the terminal by configuring at least one of the first enhanced URSP rule, the second enhanced URSP rule and the third enhanced URSP rule for the terminal in a terminal general configuration update process.

[0091] Of course, in the embodiment of the present application, at least one of the above-mentioned mapping relationship, the first enhanced URSP rule, the second enhanced URSP rule and the third enhanced URSP rule may also be a protocol agreement, which is not limited in the embodiment of the present application.

[0092] As an optional implementation manner, before the terminal obtains the routing rule auxiliary information, the method further includes:

[0093] The terminal sends capability information of supporting SL and non-3GPP short-range communication aggregate communication to the network device, and the capability information is used by the network device to configure the routing rule auxiliary information for the terminal based on the capability information and the subscription information of the terminal.

[0094] For example: Figure 4 As shown, the terminal reports the capability information of supporting SL and non-3GPP short-range communication aggregation communication to the network device. After receiving the capability information, the network device configures a mapping relationship, a first enhanced URSP rule, a second enhanced URSP rule or a third enhanced URSP rule for the terminal.

[0095] In this implementation, since the capability information is reported, it is possible to avoid the network device configuring routing rule auxiliary information for a terminal that does not have the capability, thereby saving resource overhead.

[0096] As an optional implementation manner, the routing rule auxiliary information further includes a valid time of the target communication mode, and the method further includes:

[0097] When the terminal determines the target communication method and the validity period of the target communication method has expired, the terminal switches the target communication method.

[0098] The above-mentioned effective time may be a specific time period, or the above-mentioned effective time may be the continuous transmission time of a certain business data, etc., which is not limited.

[0099] In this implementation, the terminal can switch the target communication mode when the effective time of the target communication mode is reached, that is, switch to the target communication mode only after the effective time is reached, thereby improving the management effect of terminal path switching.

[0100] As an optional implementation manner, the routing rule auxiliary information also includes valid transmission data of the target communication mode, and the method further includes:

[0101] When the terminal determines the target communication mode and effective transmission data of the target communication mode is achieved, the terminal switches the target communication mode.

[0102] The effective transmission data reaching the target communication mode may be that when the data transmitted by the communication mode currently used by the terminal reaches the effective transmission data, the terminal switches to the target communication mode for data transmission. For example, the target communication mode is the aggregated communication of SL communication and non-3GPP short-distance communication. The terminal uses SL communication. When the amount of data transmitted by SL communication reaches the effective transmission data, the terminal switches to the aggregated communication of SL communication and non-3GPP short-distance communication.

[0103] In this implementation, it can be achieved that when the effective transmission data of the target communication mode is achieved, the terminal executes the switching of the target communication mode, that is, the target communication mode is switched only after the above-mentioned effective transmission data is achieved, thereby improving the management effect of the terminal path switching.

[0104] In the embodiment of the present application, routing rule auxiliary information is obtained, and the routing rule auxiliary information is used by the terminal to perform path switching or path selection. In this way, path switching or path selection can be performed according to the routing rule auxiliary information, thereby improving the communication performance of the terminal.
