AI Technical Summary

Problems solved by technology

[0006] The terminal can establish multicast context resources and receive multicast services only after receiving the multicast paging message and the multicast establishment message. The sum of the periods, due to the consideration of air interface resource consumption, the multicast setup message sending period is generally set to be relatively large, which will lead to a large delay in the multicast reception of the terminal and affect the user experience

Embodiment 1

[0022] The process of implementing Btrunc-based signaling transmission in Embodiment 1 of the present application will be described in detail with reference to the accompanying drawings.

[0023] see figure 1 , figure 1 It is a schematic flow chart of signaling based on Btrunc in the embodiment of the present application. The specific steps are:

[0024] In step 101, the base station periodically sends a multicast paging message to the trunking terminals with a first preset period as a period.

[0025] In the embodiment of the present application, the first preset cycle of sending multicast paging messages is configured according to actual needs, and the first cycle can also be configured according to the cycle of sending multicast paging messages in the existing implementation, and the first preset cycle is not limited here. Set the specific value of the period.

[0026] Step 102, if the base station detects that there is a multicast paging message to be sent in the curre...

Embodiment 2

[0035] At present, for multicast users, there are multicast establishment messages, multicast periodic direct transmission messages, and multicast neighboring cell messages. Therefore, the three types of multicast messages consume PDCCH and PDSCH resources respectively, which will lead to waste of air interface resources. Therefore, in order to solve this problem, the present application sends the above three types of multicast signaling synchronously and periodically to save PDCCH resources. The specific implementation process is as follows:

[0036] see figure 2 , figure 2 It is a schematic flowchart of simultaneous sending of multiple types of multicast signaling in Embodiment 2 of the present application. Steps include:

[0037] In step 201, the base station combines the multicast establishment message, the multicast periodic direct transmission message and the multicast neighboring cell message that each multicast user needs to deliver periodically.

[0038] In this...

Abstract

The invention provides a signaling sending method and device based on Brunc. The method comprises the following steps: a base station periodically issues multicast paging messages by taking a first preset period as a period; and if it is detected that the multicast paging message is issued in the current sub-frame, triggering the issuing of a multicast establishment message corresponding to the multicast user. The method can reduce the multicast receiving time delay of the terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a Btrunc-based signaling sending method and device. Background technique [0002] Broadband trunking communication (Boardband Trunking Communication, Btrunc) is a TD-LTE-based "LTE digital transmission + trunking voice communication" private network broadband trunking system standard formulated by the Broadband Trunking Industry Alliance. It is characterized by flexible bandwidth, high spectral efficiency, low delay, and high reliability, and can meet the needs of professional users for multicast voice, broadband data, and emergency services. Command and dispatch and other needs. [0003] The multicast service is a typical service of the Btrunc network. In this scenario, the base station broadcasts multicast service data to multicast users. [0004] The process of establishing a multicast service is as follows: [0005] The base station will periodically deliver ...
