Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. In addition, for the sake of clarity and brevity, descriptions of known functions and configurations have been omitted.

[0175] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present disclosure. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0176] In the various embodiments of the present disclosure, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0177] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0178] The technical solution provided by the embodiment of the present disclosure can be applicable to a variety of systems, especially the fifth generation mobile communication technology (5th-Generation, 5G) system. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal devices and network devices. The system may also include core network parts, such as the Evolved Packet System (EPS), 5G System (5GS), etc.

[0179] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be two-dimensional MIMO (2D-MIMO), three-dimensional MIMO (3D-MIMO), full-dimensional MIMO (FD-MIMO), or massive MIMO. It can also use diversity transmission, precoding, or beamforming.

[0180] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0181] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0182] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0183] For supporting one or more base stations to effectively return SRS configuration, that is, specific area SRS configuration information or area-specific SRS configuration information (area-specific SRS configuration information), consider supporting the UE to directly request the base station to activate the specific area SRS configuration information or area-valid SRS configuration information. If the specific area SRS configuration information or area-valid SRS configuration information is semi-persistent SRS configuration information, the traditional SRS configuration information activation process requires the UE to send an LTE Positioning Protocol (LPP) message to the Location Management Function (LMF) device, and the LMF device requests the serving base station to allocate SRS configuration information, and then instructs it to activate the UE's SRS configuration information. As shown in Figure 1, the specific process includes:

[0184] Step 0: The LMF device may trigger the TRP Information Exchange Procedure to obtain the Transmission and Receiving Point (TRP) information required for uplink positioning; where uplink positioning includes but is not limited to: uplink Angle-of-Arrival (AOA) positioning or uplink Time Difference of Arrival (TDOA) positioning.

[0185] Step 1: The LMF device may obtain the positioning capability of the target UE based on the LPP protocol.

[0186] Step 2: The LMF device sends an NR Positioning Protocol Positioning Information Request (NRPPa POSITIONING INFORMATION REQUEST) signaling to the serving base station (the next Generation Node B, gNB) to request the uplink SRS configuration information of the target UE.

[0187] Step 3: The serving gNB determines the available uplink SRS resource allocation.

[0188] Step 3a: The serving gNB configures an uplink SRS resource set for the target UE.

[0189] Step 4: The serving gNB reports the uplink SRS configuration information to the LMF device through the NR Positioning Protocol Positioning Information Response (NRPPa POSITIONING INFORMATION RESPONSE) signaling.

[0190] Step 5a: The LMF device may request activation of UE SRS transmission and send an NR Positioning Protocol Positioning Activation Request (NRPPa POSITIONING ACTIVATION REQUEST) message to the serving gNB of the target UE, including the semi-periodic (SP) SRS resources or aperiodic (AP) SRS resources to be activated.

[0191] Step 5b: The serving gNB activates uplink SRS transmission. The target UE begins transmitting uplink SRS according to the uplink SRS resource configuration. The time domain behavior of the SRS is configured by the gNB.

[0192] Step 5c: The serving gNB sends an NR Positioning Protocol Positioning Activation Response (NRPPa POSITIONING ACTIVATION RESPONSE) message to the LMF device.

[0193] Step 6: The LMF device sends uplink SRS configuration information to the selected multiple gNBs via NR Positioning Protocol Measurement Request (NRPPa MEASUREMENT REQUEST) signaling; in some embodiments, the uplink SRS configuration information includes all information for uplink measurement performed by the gNB or TRP.

[0194] Step 7: Each gNB or TRP configured in Step 6 performs uplink SRS measurements.

[0195] Step 8: Each gNB or TRP reports the uplink SRS measurement results to the LMF device through the NR positioning protocol measurement response (NRPPa Measurement Response) signaling.

[0196] Step 9: For SP SRS or AP SRS, the LMF device sends an NR Positioning Protocol Positioning Deactivation (NRPPa POSITIONING DEACTIVATION) message to the serving gNB to stop the transmission of SP SRS or AP SRS.

[0197] The traditional SRS configuration information activation process is used to activate the SRS configuration information of a specific area or the SRS configuration information valid in a region, but there are problems of low activation efficiency and long delay.

[0198] The embodiments of the present disclosure provide a configuration information activation method, apparatus, base station, core network device, and terminal to solve the problem that there is currently no clear solution for activating SRS configuration information for a specific area when configuring the SRS configuration information for the specific area, and have the advantages of high efficiency and low latency. Among them, the method and apparatus (or base station or core network device or terminal) are based on the same application concept. Since the principles of solving the problem by the method and apparatus (or base station or core network device or terminal) are similar, the implementation of the method and apparatus (or base station or core network device or terminal) can refer to each other, and the repeated parts will not be repeated.

[0199] As shown in FIG2 , an embodiment of the present disclosure provides a method for activating configuration information, comprising the following steps:

[0200] Step 21: The first base station receives a first message sent by the terminal; wherein the first message is used to request activation of SRS configuration information, and the SRS configuration information is SRS configuration information configured based on one or more base stations.

[0201] In some embodiments, the first message may be an SRS configuration activation request message. Alternatively, the first message may be a radio resource control resume request (RRC Resume Request) message, such as an RRC Resume Request message used by a terminal to request activation of SRS configuration information when the terminal is in an inactive state. For example, when the terminal is in an inactive state, the terminal sends a first message (such as an RRC Resume Request message) to the first base station; the first message carries a resume reason indication indicating that the resume reason is a request to activate SRS configuration information.

[0202] It should be noted here that the embodiment of the present disclosure does not limit the first message to the RRC Resume Request message, that is, the first message in the embodiment of the present disclosure may also be other messages besides the RRC Resume Request message, such as new signaling, etc. The embodiment of the present disclosure is not limited to this.

[0203] In some embodiments, the SRS configuration information is SRS configuration information configured based on one or more base stations, that is, the SRS configuration information is valid for one or more base stations. Alternatively, the SRS configuration information may be referred to as area-specific SRS configuration information or area-valid SRS configuration information, etc., but the embodiments of the present disclosure are not limited thereto.

[0204] In some embodiments, the first base station may be a base station accessed by the terminal, such as a non-anchor base station or a non-serving base station. Here, the first base station being a non-anchor base station or a non-serving base station may be understood to mean that before the first base station receives the first message, the first base station is a non-anchor base station or a non-serving base station for the terminal, and does not limit the first base station from being subsequently updated to an anchor base station or a serving base station for the terminal.

[0205] Step 22: The first base station performs one of the following operations according to the first message:

[0206] activating SRS configuration information for the terminal and sending first indication information to a core network device; wherein the first indication information is used to indicate that the SRS configuration information of the terminal has been activated;

[0207] The SRS configuration information is activated for the terminal through an interaction process with the second base station and / or the core network device.

[0208] Specifically, step 22 includes: the first base station activating SRS configuration information for the terminal based on the first message and sending first indication information to the core network device; wherein the first indication information is used to indicate that the SRS configuration information of the terminal has been activated. In other words, the first base station activates the SRS configuration information for the terminal (or activates SRS transmission).

[0209] Alternatively, the first base station activates the SRS configuration information for the terminal through an interaction process with the second base station and / or the core network device based on the first message. That is, the first base station notifies the second base station or the core network device to activate the SRS configuration information for the terminal (or activate SRS transmission).

[0210] In some embodiments, the second base station may be an anchor base station or a serving base station of the terminal. Here, the second base station being an anchor base station or a serving base station can be understood as meaning that before the first base station receives the first message, the second base station is an anchor base station or a serving base station of the terminal, and does not limit the second base station from being subsequently updated to a non-anchor base station or a non-serving base station of the terminal. For example, if the second base station transfers the context of the terminal to the first base station, the first base station is updated to the anchor base station or the serving base station of the terminal.

[0211] In some embodiments, the core network device may be an LMF device, or may be other core network devices or newly added core network devices, etc., but the embodiments of the present disclosure are not limited thereto.

[0212] In this embodiment, the first base station receives a first message sent by the terminal to request activation of SRS configuration information (i.e., SRS configuration information configured based on one or more base stations), activates the SRS configuration information for the terminal based on the first message, and sends a first indication information to the core network device (i.e., notifies the core network device that the SRS configuration information of the terminal has been activated), or activates the SRS configuration information for the terminal through an interaction process with the second base station and / or the core network device, thereby enabling the base station to implement an activation scheme for configuring the SRS configuration information of a specific area.

[0213] In the embodiment of the present disclosure, the SRS configuration information is directly activated for the terminal through the first base station or the second base station, which reduces the process of the terminal sending an LPP message to the core network device and the core network device requesting the serving base station to allocate the SRS configuration information. This can improve the activation efficiency of the SRS configuration information and reduce the delay.

[0214] In some embodiments, activating SRS configuration information for the terminal and sending first indication information to the core network device includes:

[0215] The first base station activates the SRS configuration information for the terminal according to the reserved SRS configuration information and sends the first indication information to the core network device;

[0216] or,

[0217] The first base station activates the SRS configuration information for the terminal according to the SRS configuration information obtained from the second base station and sends the first indication information to the core network device.

[0218] For example, if the SRS configuration information supports one or more base stations, and the first base station belongs to the one or more base stations, the first base station can obtain the SRS configuration information, i.e., the reserved SRS configuration information, from the core network device. In this way, the first base station can directly activate the SRS configuration information for the terminal based on the reserved SRS configuration information and send the first indication information to the core network device.

[0219] In some embodiments, the first indication information may be carried in a Positioning Information Update message and reported to the core network device. It should be noted that the embodiments of the present disclosure are not limited to reporting the first indication information via the Positioning Information Update message. Other messages, such as newly added signaling, may also be used to report the first indication information, and the embodiments of the present disclosure are not limited thereto.

[0220] In some embodiments, the process of the first base station obtaining the reserved SRS configuration information from the core network device side, that is, before the first base station activates the SRS configuration information for the terminal and sends the first indication information to the core network device, further includes:

[0221] The first base station receives a fifth message sent by the core network device; wherein the fifth message carries the SRS configuration information.

[0222] Specifically, the core network device may request the serving base station (or anchor base station or second base station) of the terminal to allocate the SRS configuration information; the serving base station (or anchor base station or second base station) determines the SRS configuration information and reports it to the core network device, and the core network device may provide the SRS configuration information to one or more base stations supported by the SRS configuration information for reservation. In this way, if the first base station belongs to the one or more base stations, the first base station can obtain the reserved SRS configuration information from the core network device.

[0223] For example: the core network device may request the terminal's serving base station (or anchor base station or second base station) to allocate SRS configuration information through a Positioning Information Request message. In some embodiments, the Positioning Information Request message may carry recommended SRS valid area information (that is, the core network device recommends that the serving base station allocate one or more base stations supported by the SRS configuration information, such as the SRS valid area information may be a cell list, which may include at least one cell of a base station or at least one cell of multiple base stations). In the case where the Positioning Information Request message does not carry the recommended SRS valid area information, the serving base station (or anchor base station or second base station) may determine the valid area (such as a cell list) of the SRS configuration information. Or in the case where the Positioning Information Request message carries the recommended SRS valid area information, the serving base station (or anchor base station or second base station) can further determine the valid area of ​​the SRS configuration information based on the recommended SRS valid area information (for example, it can be all cells in the cell list recommended by the core network device; or it can also be part of the cells in the cell list recommended by the core network device; or it can also be part or all of the cells in the cell list recommended by the core network device, as well as other cells determined by the serving base station, etc.). For example: the serving base station (or anchor base station or second base station) can report the determined SRS configuration information and the corresponding valid area information to the core network device through a Positioning Information Response message, and the serving base station (or anchor base station or second base station) can also notify the terminal of the determined SRS configuration information and the corresponding valid area information.

[0224] For another example, the first base station can obtain the SRS configuration information corresponding to the terminal from the second base station (for example, the first base station may not obtain the reserved SRS configuration information from the core network device side), so that the first base station can directly activate the SRS configuration information for the terminal based on the SRS configuration information obtained from the second base station and send the first indication information to the core network device.

[0225] In some embodiments, the first base station obtains the SRS configuration information from the second base station in the following manner:

[0226] The first base station sends a second message to the second base station; wherein the second message carries second indication information, and the second indication information is used to indicate that the terminal requests to activate SRS configuration information;

[0227] The first base station receives a response message to the second message sent by the second base station; wherein the response message to the second message carries SRS configuration information corresponding to the terminal.

[0228] For example, the second message may be a context request message, meaning that the first base station may notify the second base station during the context transfer process that the terminal requests activation of SRS configuration information. Accordingly, the response message to the second message may be a context response message, meaning that the second base station may provide the SRS configuration information corresponding to the terminal to the first base station during the context transfer process.

[0229] It should be noted that the embodiments of the present disclosure are not limited to the second message being a context request message. That is, the second message may also be a message other than a context request message, such as newly added signaling. Accordingly, the embodiments of the present disclosure are not limited to the response message to the second message being a context response message. That is, the response message to the second message may also be a message other than a context response message, such as newly added signaling, and the embodiments of the present disclosure are not limited in this manner.

[0230] In one or some embodiments, when the first base station directly activates the SRS configuration information for the terminal, the first base station sends a first indication message to the core network device to indicate that the SRS configuration information corresponding to the terminal has been activated, so that the core network device can request one or more base stations supported or corresponding to the SRS configuration information (i.e., at least one base station or all base stations within the valid area corresponding to the SRS configuration information) to perform uplink SRS measurement based on the SRS configuration information corresponding to the terminal.

[0231] In some embodiments, the activating SRS configuration information for the terminal through an interaction process with the second base station and / or the core network device includes:

[0232] The first base station sends a second message to the second base station; wherein the second message carries second indication information, and the second indication information is used to indicate that the terminal requests to activate SRS configuration information;

[0233] The first base station receives a third message sent by the core network device; wherein the third message is used to request the first base station to activate SRS configuration information for the terminal;

[0234] The first base station activates SRS configuration information for the terminal according to the third message.

[0235] Specifically, when the first base station receives a first message sent by the terminal to request activation of the SRS configuration information, the anchor base station or service base station (i.e., the second base station) of the terminal can be determined through the first message, and the first base station sends a second message to the second base station to notify the second base station of the terminal's SRS configuration information activation request, and the second base station notifies the core network device of the terminal's SRS configuration information activation request, so that the core network device sends a third message to the first base station, so that the first base station can activate the SRS configuration information for the terminal (or activate SRS transmission) based on the third message sent by the core network device.

[0236] For example, when the core network device obtains the SRS configuration information activation request of the terminal from the second base station, it can call the positioning activation process to send a third message to the first base station to request the first base station to activate SRS transmission for the terminal (or called activating the SRS configuration information corresponding to the terminal). After the first base station activates the SRS configuration information for the terminal, it can also send a positioning activation response message to the core network device. At this time, the core network device can request one or more base stations corresponding to the SRS configuration information to perform uplink SRS measurement.

[0237] For example: the first base station can activate the SRS configuration information for the terminal (or activate SRS transmission) based on the reserved SRS configuration information based on the third message sent by the core network device; or, it can activate the SRS configuration information for the terminal (or activate SRS transmission) based on the SRS configuration information obtained from the second base station; or, it can activate the SRS configuration information for the terminal (or activate SRS transmission) based on the SRS configuration information obtained from the core network device side.

[0238] For example, similar to the above embodiment, the second message can be a context request message, that is, the first base station can notify the second base station during the context transfer process that the terminal requests to activate the SRS configuration information. Accordingly, if the second message is a context request message, the second base station receives the context request message, performs the context transfer process, and sends a context response message to the first base station (that is, the second base station needs to respond to the second message sent by the first base station) and notifies the core network device of the terminal's SRS configuration information activation request. Alternatively, the second message can also be other messages other than the context request message, such as new signaling, etc. (in this case, the second base station can feedback a response message for the second message sent by the first base station, or it may not feedback a response message), and the embodiments of the present disclosure are not limited to this.

[0239] In some embodiments, the process of the first base station obtaining the reserved SRS configuration information from the core network device side, that is, before the first base station activates the SRS configuration information for the terminal through an interaction process with the second base station and / or the core network device, further includes:

[0240] The first base station receives a fifth message sent by the core network device; wherein the fifth message carries the SRS configuration information.

[0241] Specifically, the core network device can request the serving base station (or anchor base station or second base station) of the terminal to allocate the SRS configuration information; the serving base station (or anchor base station or second base station) determines the SRS configuration information and reports it to the core network device, and the core network device can provide the SRS configuration information to one or more base stations supported by the SRS configuration information for reserved configuration. In this way, if the first base station belongs to the one or more base stations, the first base station can obtain the reserved SRS configuration information from the core network device. For details, please refer to the above embodiment, and repeated content will not be repeated here.

[0242] In some embodiments, after the first base station sends the second message to the second base station, the method further includes:

[0243] The first base station receives a response message to the second message sent by the second base station; wherein the response message to the second message carries SRS configuration information corresponding to the terminal.

[0244] For example, similar to the above embodiment, the second message can be a context request message, that is, the first base station can notify the second base station during the context transfer process that the terminal requests to activate the SRS configuration information. The second base station receives the context request message, performs the context transfer process, and sends a context response message (that is, a response message to the second message) to the first base station. At the same time, the context response message can carry the SRS configuration information corresponding to the terminal. That is, the second base station can provide the SRS configuration information corresponding to the terminal to the first base station during the context transfer process. In this way, when the first base station may not have reserved SRS configuration information, it can ensure that the first base station can activate SRS transmission for the terminal (or called activating the SRS configuration information corresponding to the terminal) based on the SRS configuration information obtained from the second base station.

[0245] It should be noted that the embodiments of the present disclosure are not limited to the second message being a context request message. That is, the second message may also be a message other than the context request message, such as newly added signaling. Accordingly, the embodiments of the present disclosure are not limited to the response message to the second message being a context response message. That is, the response message to the second message may also be a message other than the context response message, such as providing the first base station with SRS configuration information corresponding to the terminal via newly added signaling, and the embodiments of the present disclosure are not limited to this.

[0246] In some embodiments, the third message carries SRS configuration information corresponding to the terminal.

[0247] For example, when the core network device receives a request from the second base station to activate the terminal's SRS configuration information, it can invoke the positioning activation process to send a third message to the first base station, requesting the first base station to activate SRS transmission for the terminal (or activating the SRS configuration information corresponding to the terminal) and carrying the SRS configuration information corresponding to the terminal. This ensures that, even if the first base station may not have reserved SRS configuration information, the first base station can activate SRS transmission for the terminal (or activate the SRS configuration information corresponding to the terminal) based on the SRS configuration information obtained from the core network device.

[0248] In some embodiments, the activating SRS configuration information for the terminal through an interaction process with the second base station and / or the core network device includes:

[0249] The first base station sends a fourth message to the core network device; wherein the fourth message carries third indication information, and the third indication information is used to instruct the terminal to request activation of SRS configuration information;

[0250] The first base station receives a third message sent by the core network device; wherein the third message is used to request the first base station to activate SRS configuration information for the terminal;

[0251] The first base station activates SRS configuration information for the terminal according to the third message.

[0252] Specifically, when the first base station receives a first message sent by the terminal to request activation of SRS configuration information, the first base station sends a fourth message to the core network device to notify the core network device of the terminal's SRS configuration information activation request, so that the core network device sends a third message to the first base station. In this way, the first base station can activate the SRS configuration information for the terminal based on the third message sent by the core network device (or called activating SRS transmission).

[0253] For example, the fourth message may be a Positioning Information Update message. Of course, the embodiment of the present disclosure is not limited to the fourth message being a Positioning Information Update message, that is, the fourth message may also be other messages besides the Positioning Information Update message, such as new signaling.

[0254] For example, when the core network device obtains the SRS configuration information activation request of the terminal from the first base station, it can call the positioning activation process to send a third message to the first base station to request the first base station to activate SRS transmission for the terminal (or called activating the SRS configuration information corresponding to the terminal). After the first base station activates the SRS configuration information for the terminal, it can also send a positioning activation response message to the core network device. At this time, the core network device can request one or more base stations corresponding to the SRS configuration information to perform uplink SRS measurement.

[0255] For example: the first base station can activate the SRS configuration information for the terminal (or activate SRS transmission) based on the reserved SRS configuration information based on the third message sent by the core network device; or, it can activate the SRS configuration information for the terminal (or activate SRS transmission) based on the SRS configuration information obtained from the second base station; or, it can activate the SRS configuration information for the terminal (or activate SRS transmission) based on the SRS configuration information obtained from the core network device side.

[0256] In some embodiments, the process of the first base station obtaining the reserved SRS configuration information from the core network device side, that is, before the first base station activates the SRS configuration information for the terminal through an interaction process with the second base station and / or the core network device, further includes:

[0257] The first base station receives a fifth message sent by the core network device; wherein the fifth message carries the SRS configuration information.

[0258] Specifically, the core network device can request the serving base station (or anchor base station or second base station) of the terminal to allocate the SRS configuration information; the serving base station (or anchor base station or second base station) determines the SRS configuration information and reports it to the core network device, and the core network device can provide the SRS configuration information to one or more base stations supported by the SRS configuration information for reserved configuration. In this way, if the first base station belongs to the one or more base stations, the first base station can obtain the reserved SRS configuration information from the core network device. For details, please refer to the above embodiment, and repeated content will not be repeated here.

[0259] In some embodiments, the first base station sends a fourth message to the core network device, including:

[0260] The first base station sends a second message to the second base station; wherein the second message carries second indication information, and the second indication information is used to indicate that the terminal requests to activate SRS configuration information;

[0261] After receiving the response message to the second message sent by the second base station, the first base station sends the fourth message to the core network device.

[0262] Specifically, when the first base station receives a first message sent by the terminal to request activation of the SRS configuration information, the anchor base station or service base station (i.e., the second base station) of the terminal can be determined through the first message, and the first base station sends a second message to the second base station to notify the second base station of the terminal's SRS configuration information activation request.

[0263] For example, similar to the above embodiment, the second message can be a context request message, that is, the first base station can notify the second base station during the context transfer process that the terminal requests to activate the SRS configuration information. Accordingly, the second base station receives the context request message, performs the context transfer process, and sends a context response message to the first base station, that is, the second base station transfers the context of the terminal to the first base station, and the first base station is updated to the anchor base station or serving base station of the terminal. In this way, when the first base station obtains the context of the terminal or the first base station is updated to the anchor base station or serving base station of the terminal, the first base station can send a fourth message to the core network device to indicate the terminal's SRS configuration information activation request.

[0264] In some embodiments, the response message of the second message carries SRS configuration information corresponding to the terminal.

[0265] For example, similar to the above embodiment, the second message can be a context request message, that is, the first base station can notify the second base station during the context transfer process that the terminal requests to activate the SRS configuration information. The second base station receives the context request message, performs the context transfer process, and sends a context response message (that is, a response message to the second message) to the first base station. At the same time, the context response message can carry the SRS configuration information corresponding to the terminal. That is, the second base station can provide the SRS configuration information corresponding to the terminal to the first base station during the context transfer process. In this way, when the first base station may not have reserved SRS configuration information, it can ensure that the first base station can activate SRS transmission for the terminal (or called activating the SRS configuration information corresponding to the terminal) based on the SRS configuration information obtained from the second base station.

[0266] It should be noted here that the embodiments of the present disclosure are not limited to the second message being a context request message, and for example, the SRS configuration information activation request of the terminal is notified through other signaling or newly added signaling other than the context request message. Correspondingly, the embodiments of the present disclosure are not limited to the response message to the second message being a context response message, and for example, the SRS configuration information corresponding to the terminal is provided to the first base station through other signaling or newly added signaling other than the context response message, that is, the first base station can obtain the SRS configuration information corresponding to the terminal from the second base station in a process independent of the context transfer, etc. The embodiments of the present disclosure are not limited to this.

[0267] In some embodiments, the third message carries SRS configuration information corresponding to the terminal.

[0268] For example, when the core network device receives a request from the first base station to activate the SRS configuration information of the terminal, it can invoke the positioning activation process to send a third message to the first base station, requesting the first base station to activate SRS transmission for the terminal (or activating the SRS configuration information corresponding to the terminal) and carrying the SRS configuration information corresponding to the terminal. In this way, even if the first base station may not have reserved SRS configuration information, it can ensure that the first base station can activate SRS transmission for the terminal (or activate the SRS configuration information corresponding to the terminal) based on the SRS configuration information obtained from the core network device.

[0269] As shown in FIG3 , an embodiment of the present disclosure provides a configuration information activation method, comprising the following steps:

[0270] Step 31: The second base station receives a first message sent by the terminal; wherein the first message is used to request activation of sounding reference signal SRS configuration information, and the SRS configuration information is SRS configuration information configured based on one or more base stations.

[0271] In some embodiments, the first message may be an SRS configuration activation request message. Alternatively, the first message may be an RRC Resume Request message, such as an RRC Resume Request message used by a terminal to request activation of SRS configuration information when the terminal is in an inactive state. For example, when the terminal is in an inactive state, the terminal sends a first message (such as an RRC Resume Request message) to the first base station; the first message carries a restoration reason indication indicating that the restoration reason is a request to activate SRS configuration information.

[0272] It should be noted here that the embodiment of the present disclosure does not limit the first message to the RRC Resume Request message, that is, the first message in the embodiment of the present disclosure may also be other messages besides the RRC Resume Request message, such as new signaling, etc. The embodiment of the present disclosure is not limited to this.

[0273] In some embodiments, the SRS configuration information is SRS configuration information configured based on one or more base stations, that is, the SRS configuration information is valid for one or more base stations. Alternatively, the SRS configuration information may be referred to as area-specific SRS configuration information or area-valid SRS configuration information, etc., but the embodiments of the present disclosure are not limited thereto.

[0274] Step 32: The second base station performs one of the following operations according to the first message:

[0275] activating SRS configuration information for the terminal and sending first indication information to a core network device; wherein the first indication information is used to indicate that the SRS configuration information of the terminal has been activated;

[0276] The SRS configuration information is activated for the terminal through an interaction process with the core network device.

[0277] Specifically, step 32 includes: the second base station activating SRS configuration information for the terminal based on the first message and sending first indication information to the core network device; wherein the first indication information is used to indicate that the SRS configuration information of the terminal has been activated. In other words, the second base station activates the SRS configuration information for the terminal (or activates SRS transmission).

[0278] Alternatively, the second base station activates the SRS configuration information for the terminal through interaction with the core network device according to the first message. That is, the first base station notifies the core network device to activate the SRS configuration information for the terminal (or activate SRS transmission).

[0279] In some embodiments, the second base station may be an anchor base station or a serving base station of the terminal. The fact that the second base station is an anchor base station or a serving base station does not limit the second base station from being subsequently updated to a non-anchor base station or a non-serving base station of the terminal. For example, if the second base station transfers the context of the terminal to the first base station, the first base station is updated to the anchor base station or the serving base station of the terminal.

[0280] In some embodiments, the core network device may be an LMF device, or may be other core network devices or newly added core network devices, etc., but the embodiments of the present disclosure are not limited thereto.

[0281] In this embodiment, the second base station receives a first message sent by the terminal to request activation of SRS configuration information (i.e., SRS configuration information configured based on one or more base stations), and activates the SRS configuration information for the terminal based on the first message and sends a first indication information to the core network device (i.e., notifies the core network device that the SRS configuration information of the terminal has been activated), or activates the SRS configuration information for the terminal through an interaction process with the core network device, thereby enabling the base station to implement an activation scheme for configuring the SRS configuration information of a specific area.

[0282] In the embodiment of the present disclosure, the second base station directly activates the SRS configuration information for the terminal, which reduces the process of the terminal sending an LPP message to the core network device and the core network device requesting the serving base station to allocate the SRS configuration information. This can improve the activation efficiency of the SRS configuration information and reduce the delay.

[0283] In some embodiments, activating SRS configuration information for the terminal and sending first indication information to the core network device includes:

[0284] The second base station activates the SRS configuration information for the terminal according to the reserved SRS configuration information and sends the first indication information to the core network device.

[0285] For example, the first indication information can be carried in a Positioning Information Update message and reported to the core network device. It should be noted that the embodiments of the present disclosure are not limited to reporting the first indication information via a Positioning Information Update message. That is, other messages, such as new signaling, can also be used to report the first indication information, and the embodiments of the present disclosure are not limited to this.

[0286] In some embodiments, the process of reserving SRS configuration information includes: the core network device may request the terminal's serving base station (or anchor base station or second base station) to allocate the SRS configuration information; the serving base station (or anchor base station or second base station) determines the SRS configuration information and reports it to the core network device, and the core network device may provide the SRS configuration information to one or more base stations supported by the SRS configuration information for reserving the configuration.

[0287] For example: the core network device may request the terminal's serving base station (or anchor base station or second base station) to allocate SRS configuration information through a Positioning Information Request message. In some embodiments, the Positioning Information Request message may carry recommended SRS valid area information (that is, the core network device recommends that the serving base station allocate one or more base stations supported by the SRS configuration information, such as the SRS valid area information may be a cell list, which may include at least one cell of a base station or at least one cell of multiple base stations). In the case where the Positioning Information Request message does not carry the recommended SRS valid area information, the serving base station (or anchor base station or second base station) may determine the valid area (such as a cell list) of the SRS configuration information. Or in the case where the Positioning Information Request message carries the recommended SRS valid area information, the serving base station (or anchor base station or second base station) can further determine the valid area of ​​the SRS configuration information based on the recommended SRS valid area information (for example, it can be all cells in the cell list recommended by the core network device; or it can also be part of the cells in the cell list recommended by the core network device; or it can also be part or all of the cells in the cell list recommended by the core network device, as well as other cells determined by the serving base station, etc.). For example: the serving base station (or anchor base station or second base station) can report the determined SRS configuration information and the corresponding valid area information to the core network device through a Positioning Information Response message, and the serving base station (or anchor base station or second base station) can also notify the terminal of the determined SRS configuration information and the corresponding valid area information.

[0288] In some embodiments, the activating SRS configuration information for the terminal through an interaction process with the core network device includes:

[0289] The second base station sends a sixth message to the core network device; wherein the sixth message carries fourth indication information, and the fourth indication information is used to instruct the terminal to request activation of SRS configuration information;

[0290] The second base station receives a seventh message sent by the core network device;

[0291] The second base station activates SRS configuration information for the terminal according to the seventh message.

[0292] Specifically, when the second base station receives the first message sent by the terminal to request activation of the SRS configuration information, the second base station notifies the core network device of the terminal's SRS configuration information activation request, and the core network device sends the seventh message to the second base station. In this way, the second base station can activate the SRS configuration information for the terminal based on the seventh message sent by the core network device (or called activating SRS transmission).

[0293] For example, when the core network device learns of the SRS configuration information activation request of the terminal from the second base station, it can call the positioning activation process to send a sixth message to the second base station to request the second base station to activate SRS transmission for the terminal (or called activating the SRS configuration information corresponding to the terminal). After the second base station activates the SRS configuration information for the terminal, it can also send a positioning activation response message to the core network device. At this time, the core network device can request one or more base stations corresponding to the SRS configuration information to perform uplink SRS measurement. For example: the second base station can activate the SRS configuration information for the terminal (or called activating SRS transmission) based on the reserved SRS configuration information based on the seventh message sent by the core network device.

[0294] As shown in FIG4 , an embodiment of the present disclosure provides a configuration information activation method, comprising the following steps:

[0295] Step 41: The second base station receives a second message sent by the first base station; wherein the second message carries second indication information, and the second indication information is used to indicate that the terminal requests to activate the sounding reference signal SRS configuration information, and the SRS configuration information is SRS configuration information configured based on one or more base stations.

[0296] Step 42: The second base station activates SRS configuration information for the terminal according to the second message through an interaction process with the first base station and / or core network equipment.

[0297] In some embodiments, the activating SRS configuration information for the terminal through an interaction process with the first base station and / or the core network device includes:

[0298] The second base station sends a response message to the second message to the first base station; wherein the response message to the second message carries SRS configuration information corresponding to the terminal.

[0299] In some embodiments, the activating SRS configuration information for the terminal through an interaction process with the second base station and / or the core network device includes:

[0300] The second base station sends a sixth message to the core network device, wherein the sixth message carries at least one of the following information:

[0301] Fourth indication information, used to instruct the terminal to request activation of SRS configuration information;

[0302] The serving cell information of the terminal; for example, the second base station performs a context transfer process to transfer the terminal's context to the first base station, at which point the first base station is updated to be the terminal's anchor base station or serving base station. Upon receiving the serving cell information of the terminal, the core network device learns that the terminal's current serving base station or anchor base station is the first base station.

[0303] It should be noted that when the second base station notifies the core network device of the SRS configuration information activation request of the terminal through the sixth message, the sixth message may carry the service cell information of the terminal or may not carry the service cell information of the terminal (for example, the core network device can obtain the current service base station or anchor base station of the terminal through other processes, etc.), and the embodiments of the present disclosure are not limited to this.

[0304] In some embodiments, after the second base station receives the second message sent by the first base station, the method further includes:

[0305] The second base station performs a context transfer process according to the second message; wherein, in the context transfer process, the context of the terminal is transferred from the second base station to the first base station.

[0306] The configuration information activation method in the embodiment of the present disclosure is a second base station side behavior corresponding to the configuration information activation method on the above-mentioned first base station side.

[0307] The base station involved in the embodiments of the present disclosure (such as the first base station or the second base station) may include multiple cells providing services to the terminal. Depending on the specific application scenario, the base station may also be referred to as an access point, or may be a device in the access network that communicates with the wireless terminal through one or more sectors on the air interface, or may be called another name. The base station may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The base station may also coordinate the attribute management of the air interface. For example, the base station involved in the embodiments of the present disclosure may be a base station (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a base station (NodeB) in Wide-band Code Division Multiple Access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a 6G base station in the sixth generation mobile communication technology (6G) network architecture, a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure. In some network structures, the base station may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0308] As shown in FIG5 , an embodiment of the present disclosure provides a configuration information activation method, comprising the following steps:

[0309] Step 51: The core network device receives the fourth message sent by the first base station or receives the sixth message sent by the second base station.

[0310] Step 52: The core network device sends a third message to the first base station based on the fourth message or the sixth message; wherein, the third message is used to request the first base station to activate SRS configuration information for the terminal, and the third message carries the SRS configuration information corresponding to the terminal, and the SRS configuration information is SRS configuration information based on one or more base stations.

[0311] The configuration information activation method in the embodiment of the present disclosure includes the core network device side behavior corresponding to the configuration information activation method on the above-mentioned first base station side, and / or, the core network device side behavior corresponding to the configuration information activation method on the above-mentioned second base station side. The embodiments thereof can refer to each other and can achieve the same technical effect. To avoid repetition, they will not be repeated here.

[0312] It should be noted that the core network device and the first base station and / or the second base station in the embodiment of the present disclosure can conduct signaling interaction through an access and mobility management function (AMF) device or network element, or can also interact without going through an AMF device or network element, etc. The embodiment of the present disclosure is not limited to this.

[0313] As shown in FIG6 , an embodiment of the present disclosure provides a configuration information activation method, comprising the following steps:

[0315] Step 62: The terminal sends the first message to the first base station or the second base station; wherein the first message is used to request activation of SRS configuration information, and the SRS configuration information is SRS configuration information configured based on one or more base stations.

[0316] In some embodiments, the terminal is in an inactive state, and the first message carries the restoration reason indication for indicating that the restoration reason is a request to activate SRS configuration information.

[0317] For example, if an inactive terminal is configured with SRS information that supports one or more base stations, that is, specific area SRS configuration information or area-valid SRS configuration (srs-PosRRC-InactiveValidityAreaConfig), when the RRC layer of the terminal receives a request from a higher layer to activate the SRS configuration information, it generates a first message (such as an RRC ResumeRequest message) and sends it to the first base station or the second base station. The RRC ResumeRequest message can indicate that the resume reason is a request to activate the SRS configuration information. In some embodiments, the higher layer is the non-access stratum (NAS).
