Abstract

An embodiment floor control method includes receiving, by a mission-critical push-to-talk (MCPTT) server over an Long Term Evolution network, a first message sent by a user equipment (UE), where the first message includes an identifier of a group to which a talker corresponding to the UE belongs and a parameter indicating that an event type is a floor request, generating, by the MCPTT server, a second message according to the floor control policy and the first message, and sending the second message to the UE. The method includes receiving a response message of the second message sent by the UE, generating a first instruction message according to the response message of the second message, where the first instruction message is used to instruct a media resource function entity to perform uplink voice switching on a media plane, and sending the first instruction message to the media resource function entity.

Dependent claims

A method, comprising:

receiving, by a mission-critical push-to-talk (MCPTT) server over a Long Term Evolution (LTE) network, a first message sent by a user equipment (UE), wherein the first message comprises an identifier of a group to which a talker corresponding to the UE belongs and a parameter indicating that an event type is a floor request;
generating, by the MCPTT server, a second message according to a floor control policy and the first message, wherein the second message comprises the identifier of the group to which the talker corresponding to the UE belongs and the parameter indicating that the event type is the floor request;
sending, by the MCPTT server to the UE, the second message, wherein the second message instructs the UE to notify the talker to whom the UE belongs that a floor is granted;
receiving, by the MCPTT server, a response message to the second message, sent by the UE;
generating, by the MCPTT server, a first instruction message according to the response message to the second message;
and
sending, by the MCPTT server, the first instruction message to a media resource function entity, wherein the first instruction message instructs the media resource function entity to perform uplink voice switching on a media plane.

4 more elements

A mission-critical push-to-talk (MCPTT) server, wherein the MCPTT server comprises:

a processor;
and
a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
receive a first message sent by a user equipment (UE), wherein the first message comprises an identifier of a group to which a talker corresponding to the UE belongs and a parameter indicating that an event type is a floor request;
generate a second message according to a floor control policy and the first message, wherein the second message comprises the identifier of the group to which the talker corresponding to the UE belongs and the parameter indicating that the event type is the floor request;
send the second message to the UE, wherein the second message instructs the UE to notify the talker to whom the UE belongs that a floor is granted;
receive a response message of to second message sent, wherein the response message is sent by the UE;
generate a first instruction message according to the response message of the second message;
and
send the first instruction message to a media resource function entity, wherein the first instruction message instructs the media resource function entity to perform uplink voice switching on a media plane.
