Abstract
A method, an apparatus and a system for floor control on multiple mission critical push to talk MCPTT systems are disclosed. In an embodiment the method includes receiving, by a first floor control server, a first message from N network element devices, wherein the first message is used to request a floor from the first floor control server, and wherein the N network element devices belong to N MCPTT systems respectively, determining according to the first message, that an MCPTT user in an MCPTT group belonging to a first MCPTT system occupies the floor, wherein the first MCPTT system is an MCPTT system to which a first network element device belongs, and sending a second message to the first network element device, wherein the second message is used to indicate that the MCPTT user in the MCPTT group belonging to the first MCPTT system occupies the floor.
