Embodiment 1

[0174] Such as image 3 As shown, it is a signaling flow chart of the trunking service call user bearer establishment process according to an embodiment of the present invention, wherein the UE is a speaking user terminal and requests a trunking service call establishment request:

[0175] S301, UE and eNB complete RRC connection establishment;

[0176] S302. The UE initiates a trunking call establishment request (request information is encapsulated in NAS information) and transmits it to the MME via the eNB; the MME identifies the destination address of the request information (the trunking dispatching management center control plane interface address), and forwards the trunking service call establishment request to Cluster scheduling management center;

[0177] S303. The trunking scheduling management center authenticates the user requesting the trunking service. The authentication includes whether it is a group call member, whether the registration is successful, whether i...

Embodiment 2

[0188] In Embodiment 1, when the calling user terminal requests the trunking dispatching management center to establish a trunking service call as a group call. The trunking dispatching management center triggers the establishment process of the radio access bearer in the multicast mode for the group call in-listening user. The eNB is a base station controlling a cell in a cluster service service area. Such as Figure 4 As shown, the process of cooperative management and control between network elements in the eMBMS-based LTE system is:

[0189] image 3 After the UE and eNB establish an RRC connection, the UE initiates a group call establishment request and forwards it to the trunking dispatching management center through the MME. After the trunking dispatching management center authenticates and registers the user requesting the group call, it establishes a wireless connection for the group call listening user. The incoming bearer triggers the BM-SC to create a cluster se...

Embodiment 3

[0203] If the user equipment is a wired dispatcher, when a group call is established in multicast mode for trunking services, the process of cooperative management and control between network elements in the eMBMS-based LTE system is as follows:

[0204] The wired dispatcher initiates a group call establishment request and forwards it to the trunking dispatching management center through the MME. After the trunking dispatching management center authenticates and registers the wired dispatching station requesting the group call, it establishes a wireless access bearer for the group call listening user and triggers BM- The SC creates a cluster service session.

[0205] The specific implementation manner is the same as the steps S401-413 in the second embodiment, and will not be repeated here.

Abstract

The present invention provides a method and system for realizing a broadband digital trunking service, a trunking dispatch management center, BM-SC, MBMS-GW, MME, MCE, base station, user equipment and network side equipment, wherein the realization method includes: trunking The dispatch management center receives the cluster call establishment request; the cluster dispatch management center sends a cluster bearer creation request carrying call information and a transmission bearer address to the network side according to the cluster call establishment request. Compared with the traditional solution based on the second-generation mobile communication technology private network trunking communication system, the technical solution of the present invention can effectively meet the bandwidth requirements of the trunking service and improve transmission efficiency; in addition, it can improve the utilization rate of frequency resources; make the trunking The application of communication services has expanded from the traditional private network to the mobile public network.

Description

technical field [0001] The present invention relates to multimedia broadcast / multicast services, in particular to a method and system for realizing broadband digital trunking services, a trunking dispatch management center, a broadcast multicast service center (BM-SC), a multimedia broadcast / multicast service gateway (MBMS- GW), mobility management entity (MME), multi-service bearer equipment (MCE), base station, user equipment and network side equipment. Background technique [0002] Long-term evolution (Long Time Evolution, hereinafter referred to as LTE) is a next-generation mobile broadband network standard defined by a third-generation mobile communication system cooperation project (Third Generation Partnership Project, 3GPP). Using Orthogonal Frequency Division Multiplexing (OFDM) technology and introducing Multiple Output Multiple Output (MIMO) and other technologies; at the same time, it can support 1.25-20MHz bandwidth, which greatly improves the peak data rate and...
