Embodiment Construction

[0045] The present application provides a method for implementing a group call under hierarchical networking. The basic design concept includes: a terminal initiates a group call establishment request, and its home core network sends a group call establishment request to the group master server. Whether the group call establishment is successful is determined by the group master server (group master TCF). Group call uplink intermediate node (in the uplink transmission link of user plane media data from the core network of the group call calling party to the group master server, each TCF along the way, for example Figure 4 TCF1 and TCF2) in the group call send a group call downlink establishment request to the core network at the current level or a lower level only after receiving the group call uplink establishment success response returned by the group master control server. A group master server can also have directly managed group members.

Abstract

The invention discloses a method for realizing a group call in hierarchical networking. In the hierarchical networking, a cluster core network of each area is responsible for local cluster call scheduling business, and is also responsible for communicating with a superior core network system; and a superior cluster core network is responsible for the local cluster call scheduling business, and is also responsible for cluster call business control between a lower level core network and a lower level core network. A terminal initiates a group call establishment request, the core network to which the terminal belongs sends a group call establishment request to a master control server, and a group call uplink node sends a group call downlink establishment request to the current level or the lower level core network only when receiving group call uplink establishment success response returned by the master control server. By adoption of the scheme, the group call in the hierarchical networking can be realized.

Description

technical field [0001] The present application relates to the field of mobile communication technology, in particular to trunking communication technology, and in particular to a method for implementing group calls under hierarchical networking. 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. In the system, a large number of wireless users share a small number of wireless channels, and the command and dispatch business is the main application. It is a multi-purpose, high-efficiency wireless communication system that utilizes frequency resources. 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] The TD-LTE-based broadband multi...
