Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G). In order to better understand this application, the technical terms involved in this application are explained below. Relative position: The position of a UE relative to a network element or relative to another UE. Relative velocity: the velocity of one UE relative to another UE. Positioning, the function of detecting the geographical location (of a mobile terminal, for example) and optionally the speed. SL positioning uses PC5 to locate the UE to obtain the UE's absolute position, relative position, or ranging information. Ranging refers to determining the distance between two or more UEs and / or determining the direction of one UE (e.g., target terminal) relative to another UE (e.g., SL reference terminal) via the PC5 interface. Network-based operations involve ranging / SL positioning operations in which the 5GC network function (NF) processes service requests and calculates results. Ranging / SL positioning application identifier, a globally unique identifier used to identify a specific ranging / SL positioning application, which can be mapped to a V2X service type or a ProSe identifier. SL reference terminal (SL reference UE), a UE that supports positioning of a target terminal, for example, by using SL to transmit and / or receive reference signals for positioning, providing location-related information, etc. The target terminal (Target UE) can use SL in the ranging / SL positioning service to measure its direction and / or position with the support of one or more SL reference UEs. Located UE is a SL reference terminal that can obtain its location based on Uu positioning. Use SL positioning to determine the location of the target terminal. SL positioning client terminal (SL positioning client UE), a third-party UE other than the SL reference UE and the target UE, the SL positioning client UE can initiate a ranging / SL positioning service request. The SL positioning server UE provides method determination, assistance data allocation, and / or position calculation functionality for ranging / SL positioning services. The SL positioning server UE interacts with other UEs via PC5 to determine ranging / SL positioning methods, allocate assistance data, and calculate the position of the target UE. If any of the aforementioned functions are supported, the target UE or SL reference UE can act as the SL positioning server UE. UE positioning assisted by SL positioning and involving 5GC estimates the position of the target UE with the assistance of the network by using the positions of one or more positioning UEs and the distance and / or direction between the target UE and the positioning UE. Depending on the service request, the ranging / SL positioning results may include absolute position, relative position, or distance and direction. If the target UE decides to initiate a sidelink mobile originated location request (SL-MO-LR) procedure, information of one or more SL reference UEs / positioning UEs is included in the service request. If the location service (LCS) client or application function (AF) network element decides to obtain ranging / SL positioning results for a UE group (i.e., UE1, UE2…UEn) including n (n greater than or equal to 2) UEs, the GMLC determines a specific UE (i.e., the target UE, such as UE1) and one or more other reference / positioning UEs (e.g., UE2…UEn) among the n UEs, and then applies a sidelink mobile terminated location request (SL-MT-LR). The SL-MO-LR procedure can be triggered by the target UE's application layer. When the target UE determines that it wants to perform the SL-MO-LR procedure, it initiates a SL-MO-LR service request. For example, the target UE may be UE1 with a NAS connection, or the target UE may be connected to the network using another UE with a NAS connection from UE2 to n. The AMF serving UE1 with a NAS connection selects the LMF and triggers the LMF to provide service for the service. The SL-MO-LR request may also be triggered during the ranging / SL positioning service opening process (e.g., ranging / SL positioning service opening via the control plane through the 5GC network or ranging / SL positioning service opening via PC5). In this case, the SL positioning client UE may be a UE with a NAS connection, but requests the positioning result from UE1 to UEn, including the target UE and the related SL reference / positioning UEs (UE 2 to UEn); or the SL positioning client UE may trigger one of UE1 to UEn, which may have a NAS connection, to request the positioning result from UE1 to UEn. For the SL-MT-LR procedure, in the case where UE1 acts as the target UE, UE1 is selected to have NAS interaction for ranging / SL positioning services between the UE and LMF. For a UE that is not connected to the network, the situations in which the supplementary service message of SL-MO-LR request / response or SL-MT-LR request / response is sent include but are not limited to the following: 1) Sending a supplementary service message to the network (e.g., AMF, LMF, or GMLC) via UE1 from a UE other than UE1 connected to the network; 2) Sending a supplementary service message from the network (e.g., AMF, LMF, or GMLC) to UEs other than UE1 via UE1 connected to the network; 3) Sending a supplementary service message from UE1 (for example, UE1 is a SL client UE connected to the network) to the network (for example, AMF, LMF or GMLC). In this case, the supplementary service message is used to disclose the location information of relevant UEs other than UE1; 4) Sending a supplementary service message from the network (e.g., AMF, LMF, or GMLC) to UE1 (e.g., UE1 is a SL client UE connected to the network). In this case, the supplementary service message is used to disclose the location information of related UEs other than UE1; 5) Sending a supplementary service message from the network-connected UE1 to the network (e.g., AMF, LMF, or GMLC). In this case, the supplementary service message is triggered by a UE other than UE1; 6) Sending a supplementary service message about UEs other than the UE from the network (eg, AMF, LMF, or GMLC) to UE1 connected to the network. It should be noted that when UE1 exchanges supplementary service messages with the network, all interactions between UE1 and network elements other than AMF are carried out through the AMF. In other words, the interaction of UE1 and AMF with supplementary service messages refers to the AMF receiving, parsing, or constructing and sending supplementary service messages, and the interaction of UE1 and LMF or GMLC with supplementary service messages refers to the LMF or GMLC receiving, parsing, or constructing and sending supplementary service messages, and forwarding them between UE1 and LMF or GMLC through the AMF. In order to realize the transmission of supplementary service messages between the terminal and the network, each entity in the network can obtain information of the terminal related to the service request, thereby facilitating the execution of the service. A communication processing method, device, and storage medium provided by an embodiment of the present disclosure are described in detail below with reference to the accompanying drawings. FIG2A is an interactive schematic diagram of a communication processing method according to an embodiment of the present disclosure.

The following is an exemplary introduction to the above method. As shown in FIG8 , FIG8 is a schematic diagram of an interactive process of opening a service request result to the SL positioning client via PC5 according to an embodiment of the present disclosure. S801, when the ranging / SL positioning service is triggered, the SL positioning client UE (eg, UE1) may perform a discovery process for the ranging / SL positioning service. S802: If the discovery process is successful, the SL positioning client UE establishes a PC5 connection with the discovered UE (eg, UE2, UE3). S803, the discovered UE notifies the SL positioning client UE of UE status information, where the status information indicates whether the corresponding UE has a NAS connection or does not have a NAS connection. The SL positioning client UE may receive a list of SL reference UEs (e.g., UE3) from the target UE (e.g., UE2) via PC5 connection. S804: Based on the UE status information, the SL positioning client UE selects a UE to participate in the SL positioning operation and selects a UE (UE2 in this case) to receive the SL positioning service request. The SL positioning client UE sends a SL positioning service request, which may include information about the SL positioning client UE, information about the target UE participating in the SL positioning operation, and information about the SL reference UE, or information about the SL positioning client UE, information about UE2 used for ranging, and information about UE3. S805a, the SL positioning client UE may perform an authorization check on the service request via the SL positioning server UE, or may be performed internally by UE2. S805b, the SL positioning client UE's authorization check on the service request can be performed via 5GC. S806a: The UE (UE2 in this example) that receives the SL positioning service request selects a SL positioning server UE based on its lack of NAS connection, and performs ranging / SL positioning operations among the target UE, the SL reference UE, and the SL positioning server UE. S806b, the UE (here UE2) that receives the SL positioning service request selects a solution involving LMF based on its status of having a NAS connection. Ranging / SL positioning operations are performed between the target UE, the SL reference UE and the LMF. UE2 sends a NAS message including an SL-MO-LR request to the AMF, and also includes information of the SL positioning client UE (such as application layer ID and / or UE role) in the NAS message. The AMF that receives the information from UE2 determines that the positioning request is triggered by the SL positioning client UE for the open service request result based on the information in the NAS message. The AMF processes the message, for example, sending a positioning service request to the LMF or GMLC to obtain the desired open UE location. The AMF can perform an authorization check or trigger the LMF or GMLC to perform an authorization check. After receiving the response result, the AMF sends the corresponding information back to UE2. S807, the ranging / SL positioning result is provided by UE2 to the SL positioning client UE. As shown in FIG9 , FIG9 is a schematic diagram of an interactive process of opening a service request result to an SL positioning client via a control surface according to an embodiment of the present disclosure. S901, the application layer of the SL positioning client UE (e.g., UE1) triggers the SL positioning client to request the network to perform ranging / SL positioning services between two or more other UEs (e.g., between UE2 and UE3). (e.g., CM-IDLE) state, the service request process is first triggered to enter the connected (e.g., CM-CONNECTED) state. S902: The SL positioning client UE sends a SL-MO-LR request in an uplink NAS transport (UL NAS TRANSPORT) message to the AMF1 for ranging / SL positioning operations. AMF1 serves the SL positioning client UE. The SL-MO-LR request includes parameters required for ranging / SL positioning services, such as UE2 ID (e.g., UE2's GPSI), UE3 ID (e.g., UE3's GPSI), ranging / SL positioning service type, and required quality. The ranging / SL positioning service type may refer to the distance between two or more UEs and / or the relative positioning of one UE relative to another. The required quality may include latency, accuracy, and other parameters. The SL positioning client UE may also include information of the SL positioning client (e.g., application layer ID and / or UE role) in the NAS message, or include an indication that the purpose of triggering the process is to open the service request result, or the source terminal triggering the process is the SL positioning client, for example, the UE role of the UE initiating the request is the SL positioning client UE. S903: Based on the information received from the SL positioning client UE, the AMF1 uses the NRF query or the configuration in the AMF1 to select a GMLC that supports ranging / SL positioning services, and calls the corresponding GMLC service, such as Ngmlc_Location_ProvideRanging_request, to send the parameters received from the SL-MO-LR request to the GMLC to request ranging / SL positioning results. Optionally, the AMF can also directly forward the SL-MO-LR request transparently to the GMLC. AMF1 selects GMLC to perform other steps of the process based on the information received from UE1 (SL positioning client UE). For example, based on the information of the SL positioning client UE received in the NAS message, or the indication received in the NAS message that the purpose of triggering the process is the opening of the service request result, or the terminal received in the NAS message that triggers the process is the SL positioning client, for example, the UE role of the UE initiating the request is the SL positioning client UE, AMF1 can determine that the service request is initiated by the SL positioning client UE, and AMF1 can further perform authorization and / or privacy checks or trigger GMLC to perform further authorization and / or privacy checks by including the received information of the SL positioning client UE in the message sent to GMLC. S904, execute the SL-MT-LR procedure defined in Section 6.20.3 of the communication protocol TS 23.273[8] and make the following adjustments: - The fourth step indicates that relative positioning or ranging information is required. - In the fifth step, the GMLC selects the AMF serving UE2 or UE3 (i.e., AMF2, if the serving AMF is different from the AMF1 serving the SL positioning client UE). S905, GMLC returns the result to AMF1 through the corresponding GMLC service response, such as Ngmlc_Location_ProvideRanging_Response. S906, AMF1 returns the result to the SL positioning client UE through an uplink NAS transmission (DL NAS TRANSPORT) message. As shown in FIG10 , FIG10 is a schematic diagram of the interactive flow of the SL-MO-LR process involving LMF shown in an embodiment of the present disclosure. The SL-MO-LR procedure involving the LMF enables the UE to obtain ranging / SL positioning results using one or more other UEs with the help of the LMF in the serving PLMN for UE1. Depending on the service request, the ranging / SL positioning results may include absolute position, relative position, or distance and direction. If the target UE decides to initiate the SL-MO-LR procedure, information about one or more SL reference UEs / positioning UEs is included in the service request. S1001, can be used in communication protocol TS 23.586

[0040] The procedures and signaling specified in clause 6.2 of UE1 to UEEn are used to provide ranging / SL positioning service authorization and policies / parameters to UE1 to UEEn when they are within coverage. S1002: Based on a trigger of a service request (e.g., received from the application layer), the service request includes information of UE1 to UEn, and according to clause 6.4 of the communication protocol TS 23.586

[0040] , UE discovery is performed for ranging / SL positioning: - If UE1 is the target UE, UE1 discovers UE2 to UEn If UE1 is a positioning UE, the target UE (ie, one of UE2 to UEn) discovers UE1 (and other positioning UEs in the set of UE2 to UEn). S1003, as defined in clause 5.3 of the communication protocol TS 23.586

[0040] , establish a secure multicast and / or unicast link between UE1 to UEn to enable UE1 to exchange ranging / SL positioning protocol (RSPP) messages with each of UE2 to UEn over the PC5-U reference point, and possibly enable UE2 to UEn to exchange RSPP between each other over the PC5-U. S1004: Based on the SL positioning capabilities of UE1 to UEn, the target UE determines to perform SL-MO-LR. If UE1 is a positioning UE (i.e., when the target UE is one of UE2 to UEn and does not have a NAS connection), the target UE (e.g., UEx, one of UE2 to UEn) initiates a SL-MO-LR service request to UE1. If SL-MO-LR is established by the target UE, the SL-MO-LR request may include information about all other UEs except UEx, and may optionally include information about all n UEs of the corresponding UE role for each UE requesting the service. S1005, UE1 sends a supplementary service SL-MO-LR request to the serving AMF in the UL NAS TRANSPORT message. The MO-LR request indicates the other UE2 to UEn (using the application layer ID), any assistance data required, whether positioning calculation assistance is required, and whether the positioning result should be transmitted to the LCS client or AF. The message should include the identity of the LCS client or AF and may include the address of the GMLC, through which the LCS client and AF are accessed (via the NEF). In addition, a service type indicating which MO-LR service the UE requests from the LCS client may be included. For positioning calculation assistance from the LMF, the preferred type of ranging / SL positioning result (e.g., absolute position, relative position, or distance and direction between UE pairs) and the required QoS are included. If UE1 is a positioning UE and one of UE2 to UEn is a target UE without a NAS connection, the supplementary service SL-MO-LR request includes an indication to indicate that one of UE2 to UEn is the target UE instead of UE1, or UE1 includes the target UE information (application layer ID and / or UE role as target UE) and the SL-MO-LR request message received from the target UE in the NAS message sent to the AMF. S1006: The serving AMF selects the LMF serving UE1 (e.g., an LMF supporting ranging / SL positioning) and invokes the LMF's Nmf_LocationDetermineLocation service operation using the information from the SL-MO-LR request. The service operation includes the LCS Correlation ID. If UE1 is a positioning UE, and one of UE2 to UEn is a target UE, the target UE information and information of all other n-1 UEs are sent to the LMF. The UE information includes the UE ID and / or UE role of the relevant UE. The UE ID can be an application layer ID, SUPI or GPSI. S1007, performing ranging / SL positioning operations between UE1 and UE2 to UEn and LMF to obtain UE positions and transmit positioning results. S1008, LMF returns a response to AMF, and the response includes any ranging / SL positioning results. S1009: AMF returns a supplementary service SL-MO-LR response to UE1 in a DL NAS TRANSPORT message, and includes any ranging / SL positioning results in the message. As shown in FIG11 , FIG11 is a schematic diagram of the interactive process of the SL-ML-LR process involving LMF shown in an embodiment of the present disclosure. The positioning request is sent to the serving LMF, and the positioning request using ranging / SL positioning is determined and performed at the LMF. S1101, in the 5GC-MT-LR process using SL positioning, a positioning request terminated by the mobile terminal is sent from the GMLC, and the LMF that receives the positioning service request can be triggered using SL positioning. S1102: In the SL-MT-LR procedure, the LMF receives a positioning request for ranging / SL positioning from the GMLC and performs ranging / SL positioning based on the positioning service request. The (H)GMLC selects a UE that initiates ranging / SL positioning (e.g., UE1 in the following steps) and selects the corresponding serving AMF. When the target UE is indicated from the initiator of the request (e.g., AF, external client, or NF), but for example, if the target UE is unreachable (out of coverage), the target UE is not selected as UE1, the target UE should be one of UE2 to UEn, and the target UE should be indicated to be distinguished from other UEs, for example, by information of the UE role as the target UE. S1103, select LMF. S1104, AMF sends Nmf_Location_DetermineLocation_Request to the selected LMF. S1105 , executing steps 10 - 15 (shown as 510 - 515 in the figure) of clause 6.20.3 of the communication protocol TS 23.273 to request positioning from UE1 using ranging / SL positioning service. These steps are applicable to either the SL-MT-LR process involving LMF, or the 5GC-MT-LR process using SL positioning. In step 510, the LMF sends an SL-MT-LR request as a supplementary service message to the serving AMF using the Namf_Communication_N1N2MessageTransfer service operation, and the session ID parameter is set to the LCS Correlation identifier. The SL-MT-LR request may include the application layer ID of the other SL reference UE (eg, UE2 to UEn), the type of positioning result required in the case of relative position (eg, relative position or distance and / or direction). The SL-MT-LR request may include the application layer ID of the other UE 2 to UEn, the type of positioning result required (absolute position), the positioning UE, and the coordinate ID in the case of absolute position. In this step, if the type of positioning result required is absolute position, other UE2 to UEn are candidate positioning UEs (if included). After the LMF determines that the positioning of the target UE requires the assistance of the positioning UE, the LMF decides the target UE or the LMF selects the positioning UE, and the SL-MT-LR request also includes an indication of the target UE / LMF selects the positioning UE. If UE1 is not the target UE, the SL-MT-LR request may include information of the target UE (application layer ID and / or UE role as the target UE). If UE1 is not the target UE, in addition to the supplementary service message requested by SL-MT-LR, LMF may also send the target UE information (application layer ID and / or UE role as target UE) to AMF, and may also include an indication of forwarding the supplementary service message requested by SL-MT-LR. Step 511, the serving AMF uses the DL NAS TRANSPORT message to set the SL-MT-LR request and LCS Correlation The routing identifier (Routing ID) of the identifier is forwarded to UE1. If UE1 is not the target UE and the target UE information is received from the LMF, the AMF also includes the target UE information (application layer ID and / or UE role as the target UE) in addition to the SL-MT-LR request in the DL NAS TRANSPORT message. An indication of forwarding the supplementary service message may also be included. Step 512, if other UE2 to UEn have not been discovered using the procedure defined in clause 6.4 of the communication protocol TS 23.586

[0040] , UE1 attempts to discover other UE2 to UEn using their application layer IDs and optional coordinate IDs. If UE1 is not the target UE, based on the received target UE information in addition to the SL-MT-LR request message and the optional instruction to forward the supplementary service message, or based on the received target UE information and the optional instruction to forward the supplementary service message included in the SL-MT-LR request message, UE1 forwards the SL-MT-LR request to the target UE, or UE1 sends a SL service request to the target UE based on the received SL-MT-LR and the optional information of the target UE. The target UE performs UE discovery for the other n-1 UEs. Step 513: If not yet obtained, UE1 obtains the required SL positioning capability of the discovered UE via SLPP. If UE1 is not the target UE, it may be the target UE that obtains the required SL positioning capability of the discovered UE via SLPP (if not already obtained). In step 514, UE1 returns a supplementary service SL-MT-LR response to the serving AMF in a UL NAS TRANSPORT message, and includes the routing identifier received in step 511. The supplementary service message may include an SLPP container, which includes the ranging capability of the UE. The SL-MT-LR response includes the terminal information of the discovered UEs from UE2 to UEn. In step 514, if UE1 receives an indication from the LMF in step 511 that a positioning UE should be selected, the SL-MT-LR response includes the information of all discovered positioning UEs. The LMF performs positioning UE selection based on the information of all discovered positioning UEs. If UE1 receives an indication from the SL-MT-LR request that a target UE select a positioning UE, UE1 performs positioning UE selection, and the SL-MT-LR response includes the application layer ID of the selected positioning UE. If UE1 is not the target UE, the target UE sends an SL-MT-LR response message constructed by the target UE to UE1 for forwarding the SL-MT-LR response message to the LMF via the AMF. Alternatively, the target UE can respond to UE1 using the discovered / selected UE and SLPP container, which contains the UE's ranging capabilities for the relevant UE, and UE1 constructs an SL-MT-LR response message to send it to the LMF via the AMF. If the SL-MT-LR response message is constructed by the target UE, an indication of forwarding the supplementary service message may also be included in the message sent to UE1, and UE1 forwards the SL-MT-LR message to the AMF together with the optional target UE information. In step 515, the serving AMF forwards the SL-MT-LR response in Namf_Communication_N1MessageNotify to the LMF indicated by the routing identifier received in step 514, and the response also includes the LCS association identifier. S1106: Ranging / SL positioning is performed for UE1 and other discovered UEs through the SL-MO-LR process steps described in steps 10-19 of section 6.20.1 of communication protocol TS 23.273. The difference is that the ranging / SL positioning measurement data or results are always returned to the LMF, and the LMF indicates to UE1 in step 13 or step 14 whether the ranging / SL positioning results are calculated by the LMF (in step 19) or by UE1 (in step 17). During the positioning process, if UE1 is not the target UE, the interaction between the target UE and the network can also be implemented using the interaction methods described in the above steps. S1107: Send the positioning result to AMF in Nlmf_Location_DetermineLocation Response. In a service-based architecture (SBA), interactions between network elements can be achieved by calling services rather than sending request messages and response messages. In a non-SBA architecture, this is achieved by sending corresponding messages. For example, in SBA, sending an Ngmlc_Location_ProvideRanging request corresponds to calling the Ngmlc_Location_ProvideRanging service, and the Ngmlc_Location_ProvideRanging response corresponds to the output after the Ngmlc_Location_ProvideRanging service is executed. For example, in SBA, sending an Nlmf_Location_DetermineLocation request corresponds to calling the Nlmf_Location_DetermineLocation service, and the Nlmf_Location_DetermineLocation response corresponds to the output after the Nlmf_Location_DetermineLocation service is executed. Of course, other requests sent can also be implemented by calling the corresponding services; the response corresponding to the request corresponds to the output after the corresponding service is called, and there is no specific limitation on the request and / or response.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
