Problems solved by technology

IP / MPLS DiffServ QoS between H-TMF and V-TMF can only provide differentiated services, but cannot provide guaranteed services
Specifically: IP / MPLS DiffServQoS can provide different QoS for different services, but cannot guarantee the bandwidth, delay and packet loss rate of any service

Embodiment Construction

[0050] The embodiments of the present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the embodiments of the present invention, rather than to limit the embodiments of the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the embodiments of the present invention.

[0051] refer to figure 2 , figure 2 It is a schematic structural diagram of a system for establishing a trunking service provided by an embodiment of the present invention.

[0052] Such as figure 2 As shown, the system for establishing cluster services includes:

[0053] Enhanced mobility management entity (enhanced Mobile Management Entity, eMME), trunking control function entity (Trunking Control Function, TCF), TMF, H-xGW and V-xGW;

[0054] The eMME is co...

Abstract

The embodiment of the invention discloses a system, method and device for establishing trunking business. The method comprises the steps that user equipment initiates the trunking business to a currently attached eMME (enhanced Mobile Management Entity) through utilization of an NAS message; the eMME obtains a trunking group number carried in the NAS message, determine a TCF (Trunking Control Function) which provides service for a trunking group according to the trunking group number, and initiates a trunking business request to the TCF through utilization of an SIP message; the TCF determinesall eMMEs attached to the UE in the current trunking group and notifies all eMMEs to start the trunking business through utilization of the SIP messages; and trunking business barriers based on GTP are established between V-xGWs and H-xGWs controlled by all eMMEs. The trunking business networking of B-TrunC and LTE-M is optimized, the business quality guarantee is provided for the trunking business in a user plane, the trunking business establishment delay is reduced in the user plane, and the trunking business quality is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a system, method and device for establishing a trunking service. Background technique [0002] The B-TrunC specification formulated by the Broadband Trunking Industry Alliance and the LTE-M specification formulated by the China Urban Rail Transit Association enhance cluster functions on the basis of the Mobility Management Entity (MME) defined in the 3GPP standard, including cluster NAS signaling Its security, xGW selection, cluster bearer management, mobility management of cluster services, access control and session management. The trunking control function (Trunking Control Function, TCF) is responsible for the scheduling and management of trunking services. Its main functions include supporting multimedia trunking service scheduling including voice, video, and data, authentication and authorization of trunking services, registration and der...
