Problems solved by technology

[0004] However, the existing TD-LTE broadband trunking standard has not completely defined the specific process of how to realize the service when the terminal roams
In other words, in the TD-LTE broadband trunking system, when the terminals in the group roam, the trunking control function module (TCF: Trunking Control Function) module that provides business services for the terminals will change. However, the current TD-LTE The broadband trunking standard does not provide how the designated group master server in the group dynamically determines the TCF that provides services for the terminal according to the current location of the terminal roaming. In this way, when the terminal initiates a group call service, it will be due to The group call service cannot be quickly established because the TCF that provides services for the terminal cannot be determined

Embodiment 1

[0053] see image 3 , image 3 It is the registration flow chart of Embodiment 1 of the present invention. Such as image 3 As shown, the process may include the following steps:

[0054] Step 301: After the terminal is registered in the VDN, if the TCF network element in the VDN controls and manages the service of the terminal, it will communicate with the group master server of the group to which the terminal belongs through the Tc2-C network that has been opened. The interface sends a registration request to the group master control server on behalf of the terminal, so as to notify the group master control server of the information that the terminal is provided with the group call service by the TCF network element.

[0055] In the application, the core network that controls and manages terminal services can be preset. It can be the home domain core network of the terminal before roaming, or the visited domain core network after the terminal roams. Domain core network m...

Embodiment 2

[0072] see Figure 5 , Figure 5 It is the registration flow chart of Embodiment 2 of the present invention. Such as Figure 5 As shown, the process may include the following steps:

[0073] Step 501, after the terminal roams to the core network of the visited domain, if the TCF network element in the core network of the home domain where the terminal was located before roaming to the core network of the visited domain controls and manages the service of the terminal, the TCF network element in the core network of the home domain After the terminal registers to the core network of the visited domain, it sends a registration request to the group master server on behalf of the terminal through the opened Tc2-C interface with the group master server of the group to which the terminal belongs, so as to transfer the terminal from the core network of the visited domain. The internal TCF network element notifies the group master control server of the information about the group ca...

Abstract

The invention provides a service implementing method, system and device for a roaming terminal in a broadband cluster system. According to the service implementing method, system and device for the roaming terminal in the broadband cluster system, a TCF network element from which core network and capable of providing a group calling service to the roaming terminal can be obtained dynamically by a group main control server of a group which the terminal belongs to by controlling the TCF network element for managing terminal services to send a registration request to the group main control server of the group which the terminal belongs to. Therefore, the application scene of the roaming terminal can be well adapted, the group main control server is guaranteed to obtain the TCF network element which currently provides the group calling service to the roaming terminal dynamically and in time, and operations with extremely low efficiency, such as interface inquiry between the network elements, which are needed by the group main control server to know the TCF network element which currently provides the group calling service to the roaming terminal are avoided.

Description

technical field [0001] The present application relates to trunking communication technology, in particular to a service realization method, system and device when a terminal roams in a broadband trunking system. Background technique [0002] The trunking communication system is a dedicated wireless communication system developed to meet the command and dispatch needs of industry users and is oriented to specific industry applications. The trunking communication system has a wide range of application markets in the fields of government departments, public safety, emergency communications, electric power, civil aviation, petrochemical and military. [0003] In the trunking communication system, the broadband multimedia trunking system emerges as the times require, following the demand for broadband multimedia trunking services. TD-LTE's broadband trunking system is based on the fourth generation mobile communication technology TD-LTE as the core technology, combining the high...
