Embodiment 1

[0162] For the group call process of trunking services only, see Figure 12 , the specific process includes:

[0163] Step 1001: Firstly, the terminal initiates the RRC connection establishment, and interacts with the eNB to establish the RRC connection.

[0164] Step 1002: eNB learns that the terminal needs to initiate a group call, and then sends a group call establishment request message to the DSS (refer to the initial UE message of the LTE protocol)

[0165] The cluster core network identifier is configured in the RRC connection establishment complete message sent by the terminal, so that the eNB can know that the terminal needs to initiate a group call and which cluster core network to send the tenant establishment request to.

[0166] Optionally, the terminal may also send an RRC connection establishment request message and an RRC connection establishment complete message with a new message identifier, so that the eNB knows according to the new message identifier (diff...

Embodiment 2

[0181] When there is already an LTE connection, see Figure 13 , the specific process is described below. For simplicity, only the caller is included:

[0182] Step 1101: say that the terminal and the system have established an RRC connection and are in a service connection state;

[0183] Step 1102: When the terminal needs to initiate a trunking call and judges that the RRC connection has been successfully established, the terminal sends a trunking service request message to the eNodeB;

[0184] Step 1103: the eNB sends a group call establishment request message to the DSS.

[0185] Step 1104: PDS and PHR perform group user authentication process, and after passing authentication, DSS sends cluster initial context establishment request message to eNB;

[0186] Step 1105: capability query process (refer to the capability query process defined by the LTE protocol)

[0187] Step 1106: security process (refer to the security process defined by the LTE protocol)

[0188]Step 1...

Embodiment 3

[0202] When there is already a cluster connection, please refer to the process of establishing LTE service Figure 15 , the specific process is described below. For simplicity, only the caller is included:

[0203] Step 1301: The terminal (including the speaking terminal and the listening terminal) has established a trunking service connection with the system, and is in the trunking service connection state;

[0204] Step 1302: when the terminal needs to initiate an LTE service and judges that the RRC connection has been successfully established, the terminal sends an LTE service request message to the eNodeB;

[0205] Understandably, as described in the above embodiments, in the trunking service, the group call listening user does not need to establish an RRC connection with the eNB. Therefore, before step 2, the terminal first determines whether the RRC connection has been established. If not, it needs to Initiate the RRC connection establishment process, if established, di...

Abstract

The invention relates to a cluster service realization method, a system, a terminal, a base station and a cluster core network dispatch subsystem (DSS). The method comprises the following steps: a RRC connection establishment step; a cluster service context establishment step in which an E-UTRAN and the cluster core network dispatch subsystem (DSS) establish a cluster service context; a configuration step in which the E-UTRAN carries out cluster null interface configuration on a cluster service speaking terminal and a cluster service listening terminal; a paging step in which the E-UTRAN pages the listening terminal according to a paging message of the cluster core network dispatch subsystem; and a cluster service data forwarding step in which the E-UTRAN forwards cluster service data according to the cluster service null interface configuration. By the adoption of the cluster service realization method, the system and the network element of the invention, professional cluster services can be provided without being influenced by a LTE service.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a cluster service implementation method, system and network element (the network element mentioned here includes a terminal, a base station and a cluster core network dispatching subsystem (DSS)). Background technique [0002] The trunking communication system is a dedicated wireless communication system for specific industry applications developed to meet the command and dispatch needs of industry users. In the system, a large number of wireless users share a small number of wireless channels, and the command and dispatch is the main application. It is a multi-purpose, high-efficiency wireless communication system. [0003] The trunking communication system has experienced a development process similar to that of the cellular mobile communication system. The first generation trunking system is an analog trunking communication system, which mainly supports v...
