The information acquisition method, the indication method, the apparatus, the related device and the storage medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings and application scenarios thereof.
Referring to fig. 2, fig. 2 is a flowchart of an information obtaining method provided in an embodiment of the present application, where the method is executed by a terminal, and as shown in fig. 2, the method includes the following steps:
step 201, receiving switching indication information sent by a first network device.
The handover indication information may be indication information for instructing the terminal to handover to the second network device. In addition, the handover indication information may be received through a Radio Resource Control (RRC) reconfiguration message.
Before receiving the switching indication information, the terminal may receive the first service through the first network device. In this embodiment, the first service may belong to any service type, for example: the first service belongs to MBMS or MBS. Further, in case of MBMS or MBS, the first service may be any MBMS or MBS service, such as any defined value of Temporary Mobile Group Identity (TMGI) of the first service.
Optionally, in this embodiment of the application, a delay requirement in a Quality of Service (QoS) requirement of the first Service satisfies a first condition, for example, the first Service does not require low delay or requires low delay, and a reliability requirement in the QoS requirement of the first Service satisfies a second condition, for example, a reliability requirement of at least one of no data loss, no data error, no data repetition, and the like is high or low.
After receiving the switching indication information, the terminal may switch to the second network device, and further may receive the first service through the second network device.
In addition, in this embodiment, the terminal may be a terminal interested in the first service.
In the embodiment of the application, the switching indication information sent by the first network device is received, so that the terminal can be indicated to switch, and the service receiving performance of the terminal can be improved.
As an optional implementation, the method further comprises:
and acquiring the coverage capability information related to the first service at the network side.
Wherein, the coverage capability information may be used to indicate any one of the following:
the first service can be served in the same way in the network area;
the first traffic cannot be served in the same way within the network area.
The obtaining of the coverage capability information related to the first service on the network side may be explicitly or implicitly obtained.
One way may be to receive indication information sent by the network side, where the indication information explicitly indicates coverage capability information related to a first service on the network side, for example, the indication information indicates that the first service can be served in the same manner in a network area, or indicates that the first service cannot be served in the same manner in a network area. The specific receiving time is not limited, for example, the indication information sent by the network side may be received before receiving the first service, and specifically, the indication information sent by the network side may be received in the session joining process.
Another way may be that the network only can serve the first service in the same way in the network area, or the network area cannot serve the first service in the same way, and send the indication information, and if the terminal receives the indication information, it is determined that the first service can be served in the same way in the network area indicated by the indication information, or it is determined that the indication information indicates that the first service cannot be served in the same way in the network area. And when the terminal does not detect the indication information sent by the network, implicitly determining that the first service cannot be served in the same way in the network area or the first service can be served in the same way in the network area according to the detection result.
The first service can be served in the same manner in the network area, and a plurality of network devices in the network area can all serve the first service in the same manner, for example: the plurality of network devices are all network devices with MBMS (or MBS) capability, that is, data of the MBMS (or MBS) can be transmitted in a shared delivery (shared delivery) mode through the core network portion.
The first service that cannot be served in the same manner in the network area may be that network devices that serve the first service in different manners exist in the network area, for example: not all network devices are MBMS (or MBS) -capable network devices, that is, network devices without MBMS (or MBS) capability can only transmit MBMS or MBS in Protocol Data Unit session (PDU session) (or in independent delivery (independent delivery) mode for core network part). That is to say, the first network device is a network device having a capability of a service type corresponding to the first service, for example, the first service belongs to an MBS service, and the network device having an MBS capability, and the second network device is a network device not having a capability of a service type corresponding to the first service, for example, the first service belongs to an MBS service, and the second network device is a network device not having an MBS capability.
For example: if the first service belongs to the MBS service, the network region may be able to serve the first service in the same manner, or may be understood as a homogeneous coverage (homogeneous coverage) of the first service in the network region, and the network region may not be able to serve the first service in the same manner, or may be understood as a non-homogeneous coverage (heterogeneous coverage) of the first service in the network region.
In this embodiment, since the terminal can obtain the coverage capability information related to the first service on the network side, the capability of the terminal to obtain information can be improved because the terminal obtains more useful information, and the service capability of the terminal can also be improved because the terminal can execute a related service behavior according to the coverage capability information after obtaining the coverage capability information, so as to improve the service capability of the terminal. For example, a corresponding Non-Access-Stratum (NAS) signaling or Access-Stratum (AS) signaling is sent, and specifically, the service behavior of the terminal is not limited in the embodiments of the present application.
Optionally, before receiving the handover indication information sent by the first network device, the method further includes:
and sending a first non-access stratum (NAS) signaling according to the coverage capability information, wherein the first NAS signaling is used for triggering establishment, activation or modification of Protocol Data Unit (PDU) session resources related to the first service.
The sending of the first NAS signaling according to the coverage capability information may be sending the first NAS signaling when the coverage capability information indicates that the first service cannot be served in the same manner in a network area; alternatively, the sending the first NAS signaling according to the coverage capability information may be sending the first NAS signaling when the coverage capability information indicates that the first service can be served in the same manner in the network area.
The sending of the first NAS signaling may be sending NAS signaling to a core network through the first network device, for example, the first network device transparently transmits the first NAS signaling to the core network.
The first NAS signaling may be configured to trigger a core network to activate a PDU session resource related to the first service. The PDU session resource may be a PDU session resource that the network side has configured to send the first service to the terminal, but the resource is in a deactivated state, so that activation is triggered by the first NAS signaling.
The first NAS signaling may be used to trigger the modification of the PDU session resource related to the first service, where the first NAS signaling is used to trigger the core network to modify the PDU session resource related to the first service.
The PDU session resource related to the first service may be a PDU session resource used for transmitting service data of the first service. The first NAS signaling may be NAS signaling such as a PDU session establishment request or a service request.
In this embodiment, the PDU session resources related to the first service can be established before the handover, so that the first service can be sent in time through these PDU session resources after the terminal is handed over to the second network device, thereby improving the transmission efficiency of the first service, and also ensuring the continuity of the first service when the terminal is handed over.
It should be noted that, in this embodiment of the present application, the PDU session resource related to the first service may also be established without being triggered by the first network device, for example: and triggering the establishment, activation or modification of Protocol Data Unit (PDU) session resources related to the first service after switching to the second network equipment.
As an optional implementation manner, the handover indication information includes: a Sequence Number (SN) of service data of the first service.
The sequence number may include at least one of an SN in a Packet Data Convergence Protocol (PDCP) message and an SN in a GPRS tunneling Protocol User plane (GTP-U) message.
Further, the SN may be an SN of service data that the network has sent to the terminal, for example: and the core network sends the SN of the service data to the terminal through the first network equipment.
In this embodiment, since the handover indication information includes the sequence number of the service data of the first service, the terminal receives the service data of the first service according to the sequence number after handover, so as to further improve the service reception performance of the terminal, for example, starting to receive from the SN +1 th service data packet.
Optionally, the handover indication information includes: and the switching response message is sent by the second network equipment and comprises the SN of the service data of the first service.
In this embodiment, the SN may be included in the handover request message, and after receiving the handover request message, the second network device includes the SN in a handover request response, so as to return the SN to the terminal through the handover request response.
Of course, in the embodiment of the present application, the handover request message may not include the SN, but directly carry the SN in the handover indication information.
As an optional implementation manner, after receiving the handover indication information sent by the first network device, the method further includes:
and sending second NAS signaling, wherein the second NAS signaling is used for triggering establishment, activation or modification of PDU session resources related to the first service.
The sending of the second NAS signaling may be sending NAS signaling to the core network through the second network device, for example, the first network device transparently transmits the first NAS signaling to the core network.
The second NAS signaling may be NAS signaling such as a PDU session establishment request or a service request. The second NAS signaling is used to trigger establishment, activation, or modification of the PDU session resource related to the first service, which may refer to corresponding descriptions of the first NAS signaling and is not described herein again.
In this embodiment, it may be implemented that a PDU session resource related to the first service is established after the handover, and the network sends the first service to the terminal through the PDU session resource, so that the terminal receives the first service through the PDU session resource at the second network device, thereby improving the service receiving performance of the terminal. For example: for the MBS service insensitive to delay, the terminal can establish the PDU session resource related to the MBS service after switching, and the PDU session resource related to the MBS service does not need to be established before switching, thereby saving the resource.
Optionally, the second NAS signaling may be NAS signaling carried in the RRC reconfiguration complete message, so that an additional message is not required to be added, and resource overhead may be saved.
Optionally, the second NAS signaling includes an SN of service data of the first service. And the SN may be the SN that the first network device sends to the terminal.
In this embodiment, since the second NAS signaling includes the SN of the service data of the first service, the core network may send the service data of the first service according to the SN, so as to avoid repeated sending of the service data, and implement lossless data reception.
In the embodiment of the application, the switching indication information sent by the first network device is received, so that the terminal can be indicated to switch, and the service receiving performance of the terminal can be improved.

For example, a corresponding Non-Access-Stratum (NAS) signaling or Access-Stratum (AS) signaling is sent, and specifically, the service behavior of the terminal is not limited in the embodiments of the present application.
