Problems solved by technology
In the above-mentioned small and medium-scale network application environment, the above-mentioned existing 3GPP LTE network architecture is used to realize cluster communication. Due to the large number of network element devices, for example, only non-access layer devices need to deploy MME, HSS, S-GW, P For a series of network element devices such as -GW, for small and medium-scale network application environments, the cost of the cluster communication solution is too high, and operations such as deployment, installation, startup, and parameter configuration of many network element devices are complicated, resulting in The overall maintenance cost of the network is high, and there are many signaling exchanges between many network element devices, resulting in a large service signaling delay

Embodiment Construction
[0064] The embodiment of the present invention improves the cluster communication method, equipment and system, and proposes an LTE network equipment. One scheduler can connect to multiple LTE network equipment, and each LTE network equipment can connect to multiple UEs. The LTE network equipment is used in The UE communicates with the scheduler to realize cluster communication.
[0065] figure 2 It is a flow chart of the cluster communication method according to Embodiment 1 of the present invention. Such as figure 2 As shown, the method includes the following processes.
[0066] Step 201: The first LTE network device receives a group establishment request message or a rights preemption request message sent by the calling UE.
[0067] Step 202: The first LTE network device sends a presentation request message to the dispatcher.
[0068] In this step, the first LTE network device sends a speaker request message to the dispatcher, and through this message, the dispatcher ...

The invention provides a cluster communication method, LTE network equipment and a cluster communication system. The first LTE network device receives the group establishment request message or the preemption request message sent by the presenter UE, and sends the presenter request message to the dispatcher, and the dispatcher contacts the first LTE network device and the presenter UE according to the preset group member information. All the second LTE network devices in the group establish a group data channel, and establish a keynote data channel from the keynote UE to the dispatcher via the first LTE network equipment, and the first LTE network equipment receives the keynote data from the keynote UE on the keynote data channel and forwards it To the dispatcher, the dispatcher forwards the presentation data to the first LTE network device and the second LTE network device through the group data channel, so as to forward the presentation data to all UEs in the group to which the presentation UE belongs. By adopting the trunking communication method, LTE network equipment and trunking communication system provided by the present invention, the cost of the trunking communication system can be reduced.
Description
technical field [0001] The present invention relates to mobile communication technology, in particular to a trunking communication method, Long Term Evolution (LTE for short) network equipment and a trunking communication system. Background technique [0002] In a third generation partnership project (3rd Generation Partnership Project, 3GPP for short) fourth generation mobile communication technology (4th Generation, 4G for short) LTE system, the network side includes multiple devices. figure 1 It is a schematic diagram of a network architecture of an existing LTE system. like figure 1 As shown, the network side of the existing LTE system includes access layer network element devices and non-access layer network element devices. see figure 1 , where the network element equipment at the access layer mainly includes: an evolved base station (E-UTRAN Node B, referred to as eNB), which is used to complete the physical layer of the LTE wireless side (that is, layer 1, referre...
