Method and apparatus for floor control of intra-group point-to-multipoint communication service, and medium

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, the 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;
• wherein the terminal device with the control right corresponding to the target group is a third group terminal device in the target group;
• the sending the identification information of the terminal device with the control right to the other group terminal devices in the target group, to make the other group terminal devices request the floor from the terminal device with the control right comprises:
• sending a group call request to a second group terminal device in the target group except the third group terminal device, wherein the group call request comprises identification information of the third group terminal device, to make the second group terminal device other than the third group terminal device request the floor from the third group terminal device, wherein the second group terminal device is a terminal device in the target group other than the first group terminal device;
• sending a group call response to the first group terminal device, wherein the group call response comprises the identification information of the third group terminal device, to make the first group terminal device request the floor from the third group terminal device;
• the sending the identification information of the target group and the control right role indication to the terminal device with the control right, to make the terminal device with the control right perform the floor control operation on the group terminal device in the corresponding target group comprises:
• sending a group call request to the third group terminal device, wherein the group call request comprises the identification information of the target group and the control right role indication, to make the third group terminal device perform the floor control operation on the group terminal device in the corresponding target group.
