Embodiment Construction

[0043] In order to make the technical principles, advantages and technical effects of the technical solution of the present invention clearer, the solution of the present invention will be described in detail below through specific examples.

[0044] The solution of the present invention will be described below by taking the time division long term evolution (TD-LTE) broadband digital trunking communication system to realize the single call service as an example. The network structure of TD-LTE broadband digital trunking communication system is as follows: figure 1 As shown, it includes a terminal 110 , a broadband wireless access subsystem 120 , a network subsystem 130 , a multimedia trunking scheduling subsystem 140 and an operation and maintenance subsystem 150 .

[0045] The terminal 110 is connected with the broadband wireless access subsystem 120 or the multimedia trunking dispatching subsystem 130 through an air interface or a wired connection, and provides trunking use...

Abstract

The invention provides a method for realizing half-duplex single call service. The method can be realized through a TD-LTE (Time Division-Long-Term Evolution) wideband digital trunked communication system, and all user terminals in the system are started up to execute the adherence process, establish the default bearing and conduct trunked service registration. The method comprises the steps that: when a single call is required to be established, a calling part terminal requests a multimedia trunked dispatch server (MTDS) to establish the single call; the MTDS sends a trunked call establishment indication to a mobile management entity (MME); after receiving the trunked call establishment indication, the MME establishes the trunked bearing for the call, and the TD-LTE wideband digital trunked communication system allocates wireless resources for the calling party terminal and a called party terminal in parallel; the MME informs the MTDS that the establishment of the trunked call is completed; and the MTDS informs the calling party terminal that the single call is successfully established, and the calling party terminal owns a speech right.

Description

technical field [0001] The invention relates to the technical field of digital trunking communication, in particular to a method for realizing a half-duplex single-call service in a digital trunking communication system. Background technique [0002] The trunking communication system is a dedicated wireless communication system developed to meet the needs of industry command and dispatch, and is oriented to various industry applications. The most basic service provided by the trunking communication system is the group call service, which is a half-duplex voice call with multi-user participation established in the group call area. In the group call communication process, there is only one uplink in the group, and users in the group need to press the push-to-talk (PTT, Push To Talk) button on the user terminal to apply for or preempt the uplink when speaking; the group call area Each included cell has a downlink belonging to the group, and members belonging to the group in th...
