US 2024/0163320 A1 · METHOD AND APPARATUS FOR FLOOR CONTROL OF INTRA-GROUP POINT-TO-MULTIPOINT COMMUNICATION SERVICE, AND MEDIUM

Abstract

The present application provides a method and an apparatus for floor control of an intra-group point-to-multipoint communication service, and a medium. The method includes: receiving a group call request sent by a first group terminal device in a target group, where the group call request includes identification information of the target group; determining, according to the identification information of the target group and a mapping relationship established in advance between identification information of each group and identification information of a terminal device with a control right, a terminal device with the control right corresponding to the target group; sending identification information of the terminal device with the control right to a group terminal device in the target group, to make the group terminal device request floor from the terminal device with the control right; sending the identification information of the target group and a control right role indication to the terminal device with the control right, to make the terminal device with the control right perform a floor control operation on a group terminal device in the corresponding target group. The floor control can be performed more reasonably, and the time delay of the floor control can be effectively reduced.

Dependent claims

A method for floor control of an intra-group point-to-multipoint communication service, applied to a service center, comprising:

receiving a group call request sent by a first group terminal device in a target group, wherein the group call request comprises identification information of the target group;
determining, according to the identification information of the target group and a mapping relationship established in advance between identification information of each group and identification information of a terminal device with a control right, a terminal device with the control right corresponding to the target group;
sending identification information of the terminal device with the control right to other group terminal devices in the target group, to make the other group terminal devices request floor from the terminal device with the control right;
sending the identification information of the target group and a control right role indication to the terminal device with the control right, to make the terminal device with the control right perform a floor control operation on a group terminal device in the corresponding target group.

A method for floor control of an intra-group point-to-multipoint communication service, applied to a terminal device with a control right, comprising:

receiving identification information of a target group and a control right role indication sent by a service center;
determining itself as a terminal device with a control right in the corresponding target group according to the identification information of the target group and the control right role indication;
performing a floor control operation on a group terminal device in the corresponding target group.

A method for floor control of an intra-group point-to-multipoint communication service, applied to an SMF, comprising:

acquiring identification information of a target group and identification information list of group terminal device currently having the floor, wherein the identification information list of the group terminal device currently having the floor is determined by a service center, or the identification information list of the group terminal device currently having the floor is determined by a terminal device with a control right corresponding to the target group, after the terminal device with the control right corresponding to the target group determines, according to the identification information of the target group and a control right role indication, itself as the terminal device with the control right in the corresponding target group to perform a floor control operation on a group terminal device in the target group;
wherein the control right role indication is sent by the service center to the terminal device with the control right;
determining a current multicast data forwarding policy corresponding to each group terminal device in the target group according to the identification information of the target group and the identification information list of the group terminal device currently having the floor;
sending the current multicast data forwarding policy to a UPF corresponding to the group terminal device, to make the UPF, after receiving multicast data sent by the corresponding group terminal device, perform forwarding or discarding operation on the multicast data according to the corresponding current multicast data forwarding policy.
