Problems solved by technology

[0008] With the maturity of the third-generation mobile communication technology, the trunking communication system will also evolve into a system using 3G technology, such as time-division synchronous code-division multi-toe (TD-SCDMA) system and wide-band code-division multi-toe (WCDMA) system, etc., but At present, there is no solution to realize trunking communication based on the third generation mobile communication technology

Embodiment Construction

[0046] The method for cluster data transmission of the present embodiment includes the following steps:

[0047] Step 1, when establishing the trunking service, the radio access network establishes a group of logical channels and radio link control (RLC) entities corresponding to the logical channels for each group, and establishes a media access control MAC entity;

[0048] The MAC entity may be a Media Access Control-Trunking (MAC-t) entity.

[0049] Step 2, the wireless access network receives the data in the uplink direction of the calling user, analyzes and processes it by the MAC-t entity, and puts it into a logical channel and uploads it to the core network;

[0050] The data in the uplink direction of the calling user includes service data such as voice data and signaling data.

[0051] Step 3: The wireless access network sends the data to the RLC entity in the downlink direction, and divides the data into RLC PDUs according to the scheduling of the MAC-t entity and p...

Abstract

The invention discloses a cluster data transmission method and network-side equipment. The cluster data transmission method includes: establishing a group of logic channels and radio link control (RLC) entities corresponding to the logic channels and establishing a media access control (MAC) entity by a radio access network for a cluster during a process of an establishing cluster service; dispatching the logic channels by the MAC entity, and accessing cluster data into the logic channels by the RLC entities according to dispatching of the MAC entity; and sending the cluster data on the logic channels to receiving users by the MAC entity according to downlink resources of cells where the cluster data receiving users locate. A group of logic channels, the corresponding RLC entities and the corresponding MAC entity are established for one cluster, so that cluster communication is realized, data of a calling party are distributed to all called parties in the cluster, and data with different contents can be sent to different cells simultaneously.

Description

technical field [0001] The present invention relates to the technical field of cluster communication systems, in particular to a cluster data transmission method and network side equipment. Background technique [0002] With the development of communication technology, trunking communication technology is more and more widely used, such as ports, subways, public taxis, large-scale sports or cultural events, exhibitions, first aid and other occasions, the trunking system can play the role of dispatching and commanding , to ensure the smooth progress of various events, exhibitions and disaster relief. [0003] The current trunking communication system is developed based on the second-generation mobile communication technology, that is, GSM technology, which realizes the integration of trunking communication technology into the public mobile communication network and the integration of trunking communication services into mobile phones. [0004] The trunking communication serv...
