During the movement of the UE, there may be a situation that the signal coverage of one base station moves to the signal coverage of another base station, and the ongoing service of the UE needs to be handed over from one base station to another base station. The handover includes a handover preparation phase and a handover implementation phase, as shown in fig. 2, specifically including:

step 201: in a Handover preparation stage, signals of surrounding base stations are measured mainly by the UE, and measurement results are reported to a Source (Source) base station, wherein the measurement results include signal strength and the like, and the Source base station determines a target base station for Handover based on the measurement results.

The switching implementation stage, the source base station forwards the data to the target base station, specifically includes:

Step 203: (including steps 202a and 202 b): the source base station sends access network (RAN) usage data reports (RAN Usage Data Report) to the access and mobility management function (Access and Mobility Management Functi on, AMF) according to network requirements. The target base station sends an N2 path switch request (N2 Path Switch Request) to the AMF.

Step 204: the AMF notifies a session management function (Session Management Function, SMF) to update a related Packet Data Unit (PDU) session context through an nsmf_pdu_update SMcontext request.

Step 205-step 206: the SMF updates the N4 session context including the new N3 tunnel information. Specifically, the SMF sends an N4 session update request to the UP F (N4 Session Modification Request), and the UPF sends an N4 session update response to the SMF (N4 Session Modification Response).

Step 207: the user plane function (User Plane Function, UPF) tags the last data transmitted in each N3 tunnel with an End marker to assist in the handover. And then the data issued by the UPF are all sent to the target base station through the new N3 tunnel.

Step 208-step 209: the SMF feeds back PDU session context update result (nsmf_pduse_ UpdatSMContext Response), and the AMF notifies the target base station N2 that the path switching is completed (Path Switch Request Ack).

Step 210: and the target base station sends an instruction to inform the source base station to release related resources.

Step 211: the UE may perform a registration procedure.

The base station is used as a sensing node to send or receive sensing signals, and when the UE switches the base station, operation and parameter configuration related to sensing service are required to be switched to a target base station. At present, in the base station switching process, the sensing service cannot be switched to the target base station.

Therefore, how to switch the perceived service to the target base station during the base station switching process to keep the perceived service going on normally is a problem to be solved.

As shown in fig. 3, an embodiment of the present disclosure provides an information transmission method, which is performed by a target base station, including:

step 301: receiving a handover request from a source base station for requesting handover of a UE to the target base station, wherein the handover request at least comprises: and sensing parameter information, wherein the sensing parameter information corresponds to sensing service associated with the UE.

The UE may be a terminal such as a handset in a cellular mobile communication system. The UE may be used for a communication device that receives the awareness information. A UE may also transmit the awareness information.

The source base station and the target base station may be base stations involved in the base station handover process of the UE. The source base station may be a serving base station currently of the UE. The target base station may be a handover destination base station of the UE determined by the source base station and/or the UE during a base station handover.

In one possible implementation, the UE may send the measurements of the plurality of base stations to the source base station, from which the active base station determines the target base station.

In one possible implementation, the UE may determine the target base station according to a preset handover condition and according to a measurement result of the base station. The UE may inform the source base station of the determined target base station.

The perceived traffic may be traffic that the UE and/or the base station perceive the surrounding environment using the perceived signal. The perceived signal may be a signal used for context awareness in a cellular mobile communication system, or for both data communication and context awareness. And the UE senses the surrounding environment according to the received sensing signal. The sensing signal may be a radio frequency signal, including a millimeter wave signal, a terahertz signal, or the like.

In one possible implementation, the UE may be configured to transmit a sense signal for receipt by other communication devices (e.g., base stations) and to sense the surrounding environment.

In one possible implementation, a base station may be used to transmit a sense signal for receipt by other communication devices (e.g., UEs) and for sensing the surrounding environment.

After determining the target base station, the source base station may send a Handover Request (Handover Request) to the target base station. The handover request may carry perceptual parameter information.

And the target base station receives the switching request and acquires the sensing parameter information carried in the switching request.

The awareness parameter information may indicate configuration parameters of the awareness traffic associated with the UE. Configuration of the UE-associated awareness traffic may include resource configuration parameters of awareness traffic, awareness traffic parameters, and the like.

In one possible implementation, the sensing parameter information is used to indicate sensing configuration parameters of the base station for sensing traffic.

In one possible implementation, the perceived traffic associated with the UE includes at least one of:

a perceived service currently being performed by the UE;

and the perception service supported by the UE.

sensing signal transmission resource allocation;

and (5) sensing service configuration.

In one possible implementation, the perceived signal transmission resource configuration may include at least one of: and sensing the transmission resource allocation of the signals, and sensing the receiving resource allocation of the signals.

In one possible implementation, the perceived traffic configuration may be a configuration of related and perceived traffic, and may include at least one of: the type of the perceived service, the accuracy of the perceived service, the object of the perceived service, the quality of service QoS of the perceived service.

The type of the sensing service may be classified based on the service of the sensing service, the type of the sensing object, the transmitting end transmitting the sensing signal, the role of the UE in the sensing service, and the like.

The quality of service QoS of the awareness traffic may include QoS of communication data in the awareness service, qoS of awareness accuracy of awareness objects in the awareness service, and the like.

The business-aware objects may be classified based on motion state, such as dynamic objects and static objects. The perception objects may be classified based on actual objects, such as vehicles, buildings, etc.

The accuracy of the perceived service may be the accuracy of perceiving the perceived object, for example, the accuracy of the perceived service may include the accuracy of locating the perceived object, the accuracy of perceiving the motion state of the perceived object, and the like.

The core network may determine whether to accept a perceived service request of the UE based on the service parameter information, etc., and/or determine resources required for performing the perceived service based on the service parameter information, and allocate and configure the resources.

After receiving the sensing parameter information, the target base station can determine configuration parameters and the like of sensing services associated with the UE, and further judge whether the UE is allowed to switch.

Thus, by carrying the sensing parameter information in the switching request, the source base station can transmit the sensing parameter information of the sensing service associated with the UE to the target base station, so as to provide necessary information for switching the sensing service, and realize interaction of the sensing parameter information of the sensing service at two ends of the switching base station.

Here, the target base station may be determined by the source base station from at least one base station (handover candidate base station). The UE may perform signal measurement on at least one base station (handover candidate base station), and transmit measurement results of each base station obtained by the measurement to the source base station, from which the handover target base station is determined.

As shown in fig. 4, an embodiment of the present disclosure provides an information transmission method, which is performed by a target base station, including:

step 401: and broadcasting perception supporting information, wherein the perception supporting information is used for indicating whether the target base station supports the perception capability.

Step 401 may be performed alone or in combination with step 301.

The base station may carry the perception support information in a broadcast message for indicating whether itself supports the perception capability. The UE may determine whether the base station supports the sensing capability based on the sensing support information.

In one possible implementation, the sensing support information may include an identification bit carried in the broadcast message, which may occupy 1 or more bits, the identification bit indicating whether the base station supports sensing capability by different values.

Through the perception support information broadcast by the base station, the UE may determine the perception capability of the base station.

In one possible implementation, the UE performs measurements on a base station and sends measurement reports obtained by the measurements to a source base station, wherein the measurement reports indicate the perceptual support information comprising the base station.

Here, the sensing support information broadcasted by the base station may be the same as or different from the sensing support information carried by the UE in the measurement report. Both may be used to indicate whether the base station supports the perceptive capability and are not limited in this regard.

The UE may carry the sensing support information indicating whether the base station supports the sensing capability in the measurement report.

In one possible implementation, the source base station determines whether to determine the base station as the target base station based at least on the awareness support information and/or the awareness traffic associated with the UE.

The source base station may determine the target base station based at least on the base station's support for UE-associated awareness services. The target base station needs to meet other predetermined conditions, such as signal quality conditions, and the like, which are not described herein.

If the UE supports the perceived service and is not doing the perceived service, the source base station needs to select at least the base station supporting the perceived capability as the target base station for handover.

If the UE supports the awareness traffic but does not perform the awareness traffic, the source base station may select a base station supporting awareness or a base station not supporting awareness as a target base station for handover.

If the base station supports the sensing capability, the source base station can determine whether the UE has the sensing service requirement or not on the premise of meeting the requirements of signal measurement and the like, and the base station can serve as a target base station for switching.

As shown in fig. 5, an embodiment of the present disclosure provides an information transmission method, which is performed by a target base station, including:

step 501: and determining whether to accept the switching request or not based on the perception capability of the target base station and the perception parameter information.

Step 501 may be implemented alone or in combination with step 301 and/or step 401.

The target base station may determine whether the requirements of the configuration parameters and the like indicated by the perception parameter information can be satisfied based on its own perception capability. The perceptibility of the target base station may include whether the target base station has the ability to conduct a perceived service or not, and may also include the ability of the target base station to target specific perception parameters (e.g., specific perception accuracy).

In one embodiment, the perceptibility comprises at least one of:

whether the target base station supports sensing capability;

and the target base station supports the perception configuration.

The perceived capability of the target base station may vary due to loading, base station configuration, etc. Therefore, after receiving the handover request, the target base station can determine whether its own sensing capability can meet the requirement of sensing parameter information.

In one possible implementation, if the target base station supports the sensing capability, it may be determined that the target base station supports the sensing configuration indicated by the sensing parameter information.

In one possible implementation, if the target base station supports the sensing capability, the target base station needs to combine the sensing configuration supported by itself and the sensing configuration indicated by the sensing parameter information to determine whether the sensing configuration indicated by the sensing parameter information can be satisfied.

In one possible implementation, the perceived configuration supported by the target base station may include at least one of the following that the target base station is capable of supporting: the type of the perceived service, the accuracy of the perceived service, the object of the perceived service, the quality of service QoS of the perceived service.

In one possible implementation, if the perceptibility of the target base station does not support the perceptual parameter information, the target base station may send a handover failure response to the source base station, and indicate a cause of the handover failure in the handover failure response, e.g., the perceptibility of the target base station does not support the perceptual parameter information.

In one possible implementation, if the perceptibility of the target base station supports the perceptual parameter information, the target base station may send a handover response to the source base station than to proceed with the subsequent steps of the base station handover.

In the base station switching process, as shown in fig. 11, the information transmission flow specifically includes:

step 1101: the UE establishes a sensing service with a source NG-RAN (sNG-RAN), and sensing data is also transmitted to the UPF to a sensing processing server through the sNG-RAN.

When UE moves and needs to switch base stations

Step 1102: the base station issues a broadcast message, wherein the base station broadcast message contains an identification of whether or not to support the perceptibility (i.e., the perceptional support information).

Step 1103: the UE triggers a switching process, enters a switching preparation stage, starts to collect broadcast information of surrounding base stations when a preset threshold is reached, comprises identification information of whether sensing capability is supported or not, and reports measurement information (measurement result) to the sNG-RAN

Step 1104: the sNG-RAN selects a target NG-RAN (tNG-RAN) according to the measurement report reported by the UE. The sNG-RAN determines the target base station with reference to the current perceived service, whether the target base station supports perceived capability, and the like.

Step 1105: the sNG-RAN sends a handover request to the target base station (tNG-RAN), including the perceived parameters (i.e., perceived parameter information), such as transmit/receive resource configurations, perceived related configurations, etc.

Step 1106: and the management control is carried out, when the target base station receives the switching request, whether to accept the switching request is determined according to whether the current base station supports the sensing capability or/and the sensing requirement. And rejecting the switching request when the current base station does not support the sensing capability or sensing the requirement.

Step 1107: the target base station sends a switching completion message to the source base station, and the source base station reconfigures relevant parameters of the UE

Step 1108: the specific steps of the service switching between the source base station and the target base station are as shown in fig. 2, and are not described herein.
