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 MCPT system occupies the floor.

Abstract: The present disclosure provides a call establishment method and system, and user equipment. A first UE broadcasts a call establishment message, where the call establishment message includes an identifier of the first UE and a called party identifier, and the called party identifier is used to indicate a group or UE called by the first UE; receives a first call response message sent by a second UE, where the first call response message includes an identifier of the second UE; and establishes, according to the received first call response message, a call connection to the second UE. In this way, any UE broadcasts a call establishment message in an offline state, and establishes, in a point-to-point manner, a call connection to another UE sending a call response. Therefore, this effectively improves a fixed call establishment manner in a DMO scenario, and improves flexibility of group call establishment in an offline case.

Abstract: A method, a system and a device for maintaining user service continuity are provided in an embodiment of the present invention. The method includes prohibiting a UE from accessing a forbidden network before handover is complete when the UE needs to perform network handover if the UE adopts a SIM access technology, thus avoiding service interruption of a SIM user due to access to an incorrect network. A system and a device for maintaining user service continuity are provided in an embodiment of the present invention.
