Embodiment 1

[0112] Such as figure 2 As shown in , the UE is the calling user terminal and requests to send a group call setup request. The eNB is the base station that controls the cell where the UE resides. When a trunking service multicast mode group call is established, the process of cooperative management and control between network elements in the eMBMS-based LTE system is as follows:

[0113] S01-S02: After the UE establishes an RRC connection with the eNB, the UE initiates a group call establishment request and sends it to the MME via the eNB;

[0114] S03: The MME forwards the call establishment request to the trunking dispatching management center after identifying it as a trunking service call establishment request.

[0115] S04: The cluster dispatching management center authenticates and registers the user who requests the group call;

[0116] S05: After the authentication is passed, the trunking dispatching management center encapsulates the call information of the group ...

Embodiment 2

[0132] If the user equipment is a wired dispatcher, when a trunking service multicast mode group call is established, the process of cooperative management and control between network elements in the eMBMS-based LTE system is as follows:

[0133] S101: The wired dispatcher sends a group call establishment request to the PDN-GW through the cable, or forwards the group call establishment request to the PDN-GW through the D-GW (data gateway);

[0134] S102: The PDN-GW forwards the group call establishment request to the cluster scheduling management center;

[0135] S103: The cluster dispatching management center authenticates and registers the user who requests the group call;

[0136]S104: After the authentication is passed, the trunking dispatching management center encapsulates the call information of the group call in the trunking service response, and then sends the trunking service response and a request for creating a trunking bearer to the PDN-GW; the call information in...

Embodiment 3

[0150] Such as image 3 As shown, the UE is the calling user terminal and requests to send a trunking service call request. The eNB is the base station that controls the cell where the UE resides. When a cluster service unicast mode is established, the process of cooperative management and control between network elements in the eMBMS-based LTE system is as follows:

[0151] S201-S202 After the UE establishes an RRC connection with the eNB, the UE initiates a trunking service call request and transmits it to the MME via the eNB;

[0152] S203: After the MME recognizes the trunking service call establishment request, it forwards the request to the trunking dispatching management center.

[0153] S204: The cluster scheduling management center authenticates the user requesting the cluster service;

[0154] S205: After passing the authentication, the trunking dispatching management center encapsulates the call information of the trunking service user in the call response, and t...

Abstract

The invention provides a time division long term evolution (TD-LTE) broadband digital cluster business application appliance, a system and a method based on an enhanced multimedia broadcast multicast service (eMBMS). The method comprises that a packet data network gateway (PDN-GW) can be used for receiving the cluster business responding and founding cluster loading requests sent by a cluster scheduling management center and the cluster business responding and founding cluster loading requests can be transponded to a gateway, wherein the gateway is used for supporting a cluster business playing specialty. The cluster business responding and founding cluster loading requests are transponded a mobile management entity (MME) by the gateway. After the MME is configured with transmission bearing information, a wireless access bearer establishment can be launched to a base station with the transmission bearing information. After the base station is used for completing the wireless access bearer establishment, cluster business convention can be returned to the cluster scheduling management center to found a response by the MME. The TD-LTE broadband digital cluster business application appliance, the system and the method can be used for regarding a cluster communication as a business to integrate into a public honeycomb mobile system.

Description

technical field [0001] The present invention relates to a TD-LTE (Time Division-Long Time Evolution, hereinafter referred to as TD-LTE) system based on an eMBMS (Enhanced Multimedia Broadcast Multicast Service, multimedia broadcast / multicast service) architecture, carrying broadband digital trunking services Implemented devices, systems and methods. Background technique [0002] LTE is a next-generation mobile broadband network standard defined by 3GPP (Third Generation Partnership Project, third-generation mobile communication system cooperation project). Using OFDM technology and introducing MIMO (multiple output multiple output) and other technologies; at the same time, it can support 1.25-20MHz bandwidth, which greatly improves the peak data rate and system capacity, and supports the peak rate of downlink 100Mbit / s and uplink 50Mbit / s under 20Mhz bandwidth ; The flat network structure enhances the efficiency of scheduling and radio resource control, and shortens the con...
