Embodiment 1

[0174] Such as image 3 Shown is a signaling flow chart of the process of establishing a trunk service speaking right user bearer in an embodiment of the present invention, where the UE is a speaking right user terminal and requests a trunk service call establishment request:

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

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

[0177] S303. The cluster dispatching management center authenticates the user requesting the cluster service, and the authentication includes whether they are group call members, whether the registration is successful, whether they have t...

Embodiment 2

[0188] When the calling user terminal requests the trunking dispatch management center to establish a trunking service call in the first embodiment, it is a group call. The group scheduling management center triggers the establishment of the radio access bearer in the multicast mode for the listening users in the group call. The eNB is a base station that controls a cell in a cluster 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 RRC connection is established between the UE and the eNB, the UE initiates a group call establishment request and forwards it to the trunking scheduling management center through the MME. After the trunking scheduling management center authenticates and registers the user requesting the group call, it establishes a wireless connection for the group call user. Incoming bearer triggers the BM-SC to create a cluster service se...

Embodiment 3

[0203] If the user equipment is a wired dispatching station, when a group call is established in a group service multicast mode, the process of cooperative management and control between network elements in the eMBMS-based LTE system is:

[0204] The wired dispatching station 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 user and triggers BM- The SC creates a cluster service session.

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

Abstract

The invention provides an implementation method and system of a broadband digital cluster service, a cluster dispatching management center, a BM-SC, an MBMS-GW, an MME, an MCE, a base station, user equipment and a network side device. The implementation method of the broadband digital cluster service comprises the steps that (1) the cluster dispatching management center receives a cluster call establishment request; (2) the cluster dispatching management center sends a created cluster bearing request carrying calling information and a transmission bearing address to a network side according to the cluster call establishment request. Compared with a solution of a private network cluster communication system which is built on the basis of the second generation mobile communication technology, according to the technical scheme, the requirement for the broadband of the cluster service can be effectively met, and transmission efficiency is improved. In addition, the utilization rate of frequency resources can be improved, and application of a cluster communication service is expanded from a traditional private network to a mobile public network.

Description

Technical field [0001] The present invention relates to multimedia broadcast / multicast services, in particular to a method and system for implementing broadband digital trunking services, trunking dispatch management center, broadcast multicast service center (BM-SC), multimedia broadcast / multicast service gateway (MBMS- GW), mobility management entity (MME), multi-service integrated bearer equipment (MCE), base station, user equipment and network side equipment. Background technique [0002] Long Time Evolution (Long Time Evolution, hereinafter referred to as LTE) is a next-generation mobile broadband network standard defined by the Third Generation Partnership Project (3GPP). Adopt orthogonal frequency division multiplexing (OFDM) technology and introduce multiple output multiple output (MIMO) technologies; at the same time, it can support 1.25-20MHz bandwidth, which greatly improves the peak data rate and system capacity, and supports 100Mbit / s downlink under 20Mhz bandwidth ...
