Example Embodiment

[0025] figure 1 This is a flowchart of Embodiment 1 of the method for implementing a group service according to the present invention. The method described in this embodiment mainly introduces the process of establishing a group service. As shown in the figure, the method includes the following steps:

[0026] Step 110: The speaker terminal sends a group establishment request to the core network.

[0027] Specifically, such as figure 2 As shown in, the speaker terminal can first carry the PTT Speaker Request in the RRC Connection Setup Complete message and send it to the speaker side base station, and then the speaker side base station establishes the group The request is carried in an Initial UE Message (Initial UE Message) and sent to the core network.

[0028] Wherein, the RRC connection establishment complete message is a message used when an RRC signaling connection is established between the speaker terminal and the speaker side base station. As shown in the figure, the spea...

Abstract

The invention provides a time division-long term evolution (TD-LTE) digital trunked communication system and a group service implementing method. The method comprises the steps that an initial terminal sends group set-up requests to a core network; the core network searches a monitoring side cell in a list of a pre-set tracking area according to the group set-up requests, wherein a corresponding monitoring terminal is located in the monitoring side cell; the core network sets initial resources for the initial terminal and sets group resources for an initial side cell where the initial terminal is located and the monitoring side cell; and when the core network receives that group resources responded by a monitoring side base station in the monitoring side cell successfully set up responses, a speaking right is granted to the initial terminal. According to the TD-LTE digital trunked communication system and the group service implementing method, a set-up process of the initial resources and a set-up process of the group resources are executed in a parallel mode, and therefore set-up speed of group services is largely improved, and set-up time delay is reduced.

Description

technical field [0001] The invention relates to a TD-LTE (Time Division-Long Term Evolution, Time Division-Long Term Evolution) digital trunking communication system and a group service realization method, belonging to the technical field of trunking communication. Background technique [0002] The TD-LTE digital trunking communication system is a private network system based on TD-LTE technology. It is similar to the traditional digital trunking communication system not implemented by TD-LTE technology. requirements. [0003] However, the air interface standard of TD-LTE on the existing public network is mainly aimed at the point-to-point unicast communication mechanism and the multicast communication mechanism of Multimedia Broadcast Multicast Service (MBMS), while the private network is aimed at For the point-to-multipoint half-duplex communication mechanism of group users, if the existing TD-LTE technical standard applied to the public network is simply applied to the p...
