Specifically, when the terminal device wants to create a group, the terminal device may send a first message to the network device, and request the network device to create the group through the first message, optionally, the first message may include related information for creating the group, so that the network device may determine whether to create the group according to the related information, and further may send feedback information to the terminal device through a first response message.

Optionally, the information related to creating the group may include information of group members that the terminal device requests to join the group, so that the network device may send a request message to the group members in the group after successfully creating the group, to request the group members in the group to join the group.

Alternatively, the related information for creating the group may include identification information or address information of the terminal device or a reason why the terminal device created the group, for example, for use in company offices, or home use, or the like.

Optionally, in this embodiment of the present application, the group member information that the terminal device requests to join the group may be sent through the first message, or may also be sent through another message after the first message, that is, the terminal device may carry information of the group member in the first message, or may also send the group member information that requests to join the group to the network device through another message after sending the first message, which is not limited in this embodiment of the present application.

In this embodiment of the application, after receiving the first message, the network device may first determine whether the terminal device has the authority to create the group, and determine whether to create the group according to the authority of the terminal device. If the terminal device has the right to create the group, the network device determines to create the group, and further, may send the first response message to the network device to indicate that creating the group is successful. Alternatively, the first response message may include group identification information or address information allocated for the group. Or, if the terminal device does not have the authority to create the group, the network device may feed back, to the terminal device, a group creation failure or a group creation rejection, in this case, the first response message may include a failure reason or a rejection reason, and the failure reason or the rejection reason may be that the terminal device does not have the authority to create the group.

Optionally, in some cases, in a case that the terminal device has a right to create the group, the network device may further determine whether to create the group in combination with attribute information of a group that the network device supports creating, for example, if the network device supports creating the group of the attribute information that the terminal device requests to create, the network device may determine to create the group. Alternatively, if the network device does not support creation of the group of attribute information, the network device may determine to refuse creation of the group. Alternatively, in a case where the terminal device has the authority, if the terminal device does not allow creation of the group of the attribute information, the network device may refuse creation of the group. Further, the network device may feed back to the terminal device that creation of the group failed or refused, and optionally, the first response message may include attribute information of a group that the network device supports creation or default attribute information.

Optionally, in some embodiments, the network device determines the authority of the terminal device according to subscription information and/or a preset policy of the terminal device.

For example, if the subscription information of the terminal device includes capability information of a group created by the terminal device, the capability information of the created group may be used to indicate whether the terminal device has a capability of creating the group, or may also be used to indicate which attribute information group the terminal device has a capability of creating, and therefore, the capability of creating the group of the terminal device may be understood as whether the terminal device has a capability of requesting to create the group or a capability of requesting to create a group of specific attribute information.

Optionally, the preset policy may be pre-configured capability information of the created group of the terminal device, and the capability information of the created group of the terminal device may refer to the above description, and for brevity, is not described herein again.

Optionally, in some embodiments, before S210, the method 200 may further include:

and the terminal equipment acquires the capability information of the network equipment creation group.

Here, the capability information of the network device creating group may be used to indicate whether the network device has a capability of creating a group, or may also be used to indicate which attribute information groups the network device has a capability of creating, so that the terminal device may determine the attribute information of the group carried in the first message according to the capability information of the network device creating group, which is beneficial to avoiding that a group creation failure affects user experience.

Optionally, in some embodiments, the obtaining, by the terminal device, capability information of the network device creation group includes: and the terminal equipment acquires the capability information of the network equipment creation group through a broadcast message or a special signaling.

Optionally, the dedicated signaling is Radio Resource Control (RRC) signaling or Non-Access Stratum (NAS) signaling, and the like, which is not limited in this embodiment of the present invention.

and the terminal equipment determines the attribute information for creating the group carried in the first message.

Optionally, in some embodiments, the preset policy may be configured by the network device, or preconfigured on the terminal device, or determined according to subscription information of the terminal device, and the like, which is not limited in this embodiment of the application.

Optionally, in some embodiments, before S210, the method 200 further includes:

and the terminal equipment sends a second message to the network equipment, wherein the second message is used for informing the network equipment of the capability information of the terminal equipment for creating the group.

The capability information of the terminal device creation group may be used by the network device to determine whether to create the group for the terminal device. For example, if the terminal device does not have the capability of creating a group, the network device may determine to reject creating the group, or if the terminal device does not have the capability of creating a group with a specific attribute, and the terminal device requests the network device to create the group with the specific attribute, in which case, the network device may also reject creating the group with the specific attribute.

Optionally, in some embodiments, if the first message includes information of group members in the group, that is, the terminal device requests which terminal devices join the group, the network device may send a fourth message to the group members in the group to request the group members in the group to join the group, and the group members may approve joining the group, or may reject joining the group, and the group members may reply to the network device with a fourth response message to indicate whether to approve joining the group.

Optionally, if the first message does not include information of group members in the group, the network device may determine the group members in the group according to the subscription information of the terminal device, and further may initiate a request message to the group members in the group to request the group members in the group to join the group, where the specific process refers to the foregoing description, and is not described here again.

Optionally, in some embodiments, the Network device may further create a corresponding Network connection for the group, where the Network connection may be a session connection, or a Packet Data Network (PDN) connection or bearer, which is used for communication between terminal devices, and this is not limited in this embodiment of the present application. In some cases, the creation of a group may be performed simultaneously with the network connection establishment process, i.e., the corresponding network connection is created at the same time the group is created. For example, if the network device is an AMF entity or an SMF entity, the network device may establish a network connection corresponding to the group for communication between members in the group while determining that the group can be created, upon receiving the first message from the terminal device.

For another example, if the network device is a network entity other than the AMF entity and the SMF entity, the network connection establishment process may be initiated by the terminal device, the network device may receive a network connection establishment request of the terminal device, where the network connection establishment request may include attribute information, such as group identification information, external network service node information, or attribute information of a group suggested to be created by the terminal device, and the network device may establish, for the group, a corresponding network connection and corresponding channel information using the attribute information, where the channel is used to connect respective network connections of group members, so as to implement data routing between the group members.

Optionally, in other embodiments, the method 200 may further include:

the terminal device may send a third message to the network device requesting deletion of the group.

Optionally, the information included in the third message may refer to the content included in the first message, which is not described herein again.

After receiving the third message, the network device may first determine whether the terminal device has the right to delete the group, and if the terminal device has the right to delete the group, the network device may delete the group and feed back a third response message to the terminal device, which is used to indicate that the group deletion is successful. Or, if the terminal device does not have the right to delete the group, the network device may feed back to the terminal device that the group deletion failed or reject to delete the group. Optionally, the third response message may include a failure reason or a rejection reason, for example, the failure reason or the rejection reason may be that the terminal device does not have the right to delete the group.

Optionally, in some embodiments, when deleting a group, the network device may delete context information related to the group at the same time, for example, security information of the group or channel information established for the group, for example, a network Protocol (Internet Protocol, IP) channel or a General Packet Radio Service tunneling Protocol-User Plane (GTP-U) tunnel, etc.

Optionally, the group deletion process in the embodiment of the present application may be implemented by network connection deletion or network connection deactivation.

Therefore, according to the wireless communication method in the embodiment of the present application, the network device may initiate a group creation or deletion process based on a request of the terminal device, so that effective and secure management of the local network group can be achieved.
