The information acquisition method, the indication method, the device, the related equipment and the storage medium provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.

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 performed by a terminal, as shown in fig. 2, and 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 indicating that the terminal is handed over to the second network device. In addition, the handover indication information may be received through a radio resource control (Radio Resource Control, RRC) reconfiguration message.

Before receiving the handover indication information, the terminal may receive a first service through the first network device. In the embodiment of the present application, the first service may belong to any service type, for example: the first service belongs to MBMS or MBS. Further, if MBMS or MBS, the first service may be any MBMS or MBS service, such as any defined value for the temporary mobile group identity (Temporary Mobile Group Identity, TMGI) of the first service.

Optionally, in the embodiment of the present application, the delay requirement in the quality of service (Quality of Service, qoS) requirement of the first service meets a first condition, for example, the first service does not require low delay or requires low delay, and the reliability requirement in the QoS requirement of the first service meets a second condition, for example, the reliability requirement of at least one of data loss-free, data error-free, data repetition-free, etc. is high or low.

After receiving the switching indication information, the terminal can switch to the second network device, and further, can receive the first service through the second network device.

In addition, in the embodiment of the present application, the terminal may be a terminal interested in the first service.

As an alternative embodiment, the method further comprises:

Wherein, the coverage capability information may be used to represent any one of the following:

The first service can be served in the same way in the network area;

The first traffic cannot be serviced in the same manner within the network area.

The obtaining the coverage capability information related to the first service on the network side may be obtained by an explicit or implicit manner.

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, and if the indication information indicates that the first service can be served in the same manner in the network area, or indicates that the first service cannot be served in the same manner in the network area. The specific receiving time is not limited, for example, the indication information sent by the network side may be received before the first service is received, specifically, the indication information sent by the network side may be received in the session joining process, and of course, the embodiment of the present application may also be used to receive the indication information sent by the network side when the first service is received.

Alternatively, the network may send the indication information only if the first service can be served in the same manner in the network area, or if the first service cannot be served in the same manner in the network area, and if the terminal receives the indication information, it is determined that the first service can be served in the same manner in the network area indicated by the indication information, or it is determined that the first service cannot be served in the same manner in the network area indicated by the indication information. 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 manner in the network area or the first service cannot be served in the same manner in the network area according to the detection result.

The first service may be served in the same manner in the network area, and the plurality of network devices in the network area may 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, the data of the MBMS (or MBS) may be sent by the core network part in a shared delivery (SHARED DELIVERY) manner.

The inability to serve the first service in the same manner in the network area may be that there are network devices serving the first service in different manners in the network area, for example: not all network devices are MBMS (or MBS) -capable network devices, i.e. network devices that are not MBMS (or MBS) -capable can only send MBMS or MBS in the form of a protocol data unit session (Protocol Data Unit session, PDU session) (or with the core network part being a separate delivery (individual delivery)). That is, 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 has 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: the first service belongs to the MBS service, and the service in the network area can be served in the same manner and can be understood as the first service in the network area is covered (homogeneously covered) in a homogeneous manner, and the service in the network area cannot be served in the same manner and can be understood as the first service in the network area is covered (not homogeneously covered) in a heterogeneous manner.

In this embodiment, since the terminal may obtain coverage capability information related to the first service on the network side, the capability of the terminal for obtaining information may be improved, since the terminal obtains more useful information, and the service capability of the terminal may also be improved, since the terminal may perform related service actions according to the coverage capability information after obtaining the coverage capability information, so as to improve the service capability of the terminal. For example, sending corresponding Non-Access-Stratum (NAS) signaling or Access-Stratum (AS) signaling, etc., the embodiment of the present application does not limit the service behavior of the terminal.

Optionally, before the receiving the handover indication information sent by the first network device, the method further includes:

And sending a first NAS signaling according to the coverage capability information, wherein the first NAS signaling is used for triggering the establishment, activation or modification of protocol data unit PDU session resources related to the first service.

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 cannot be served in the same manner in the network area; or 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 the first NAS signaling may be sending NAS signaling to the core network through the first network device, for example, the first network device transparently transmits the first NAS signaling to the core network.

The triggering of the first NAS signaling to activate the PDU session resource related to the first service may be that the first NAS signaling is used to trigger the core network to activate the 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 is used to trigger modification of PDU session resources related to the first service, and the first NAS signaling is used to trigger modification of PDU session resources related to the first service by a core network.

The PDU session resource related to the first service may be a PDU session resource 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 may be established before the handover, so that the first service may be sent through the PDU session resources in time after the terminal is handed over to the second network device, so as to improve the transmission efficiency of the first service, and further, ensure continuity of the first service when the terminal is handed over.

It should be noted that, in the embodiment of the present application, the PDU session resource related to the first service may be set up without being triggered by the first network device, for example: and triggering to establish, activate or modify the protocol data unit PDU session resource related to the first service again after switching to the second network device.

As an optional embodiment, the handover instruction 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 (PACKET DATA Convergence Protocol, PDCP) message and an SN in a GPRS tunneling protocol user plane (GPRS Tunnel Protocol User, GTP-U) message.

Further, the SN may be an SN of service data that has been sent by the network to the terminal, for example: 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 receiving performance of the terminal, for example, from the sn+1th service data packet.

Optionally, the handover indication information includes: and the switching response message sent by the second network equipment 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 the second network device may include the SN in the handover request response after receiving the handover request message, so that the SN is returned to the terminal through the handover request response.

Of course, in the embodiment of the present application, the SN may not be included in the handover request message, but may be directly carried in the handover indication information.

As an optional implementation manner, after the 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 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 may be used to trigger establishment, activation or modification of PDU session resources related to the first service, and may be referred to in the corresponding description of the first NAS signaling, which is not described herein.

In this embodiment, the establishment of the PDU session resource related to the first service after the handover may be implemented, 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 in the second network device, so as to improve the service receiving performance of the terminal. For example: for delay insensitive MBS services, the terminal can establish PDU session resources related to the MBS services after switching, and the PDU session resources related to the MBS services are not required to be established before switching, so that resources are saved.

Optionally, the second NAS signaling may be NAS signaling carried in the RRC reconfiguration complete message, so that resource overhead may be saved because no additional message needs to be added.

Optionally, the second NAS signaling includes 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 may implement lossless data reception.
