Embodiment 1

[0080] Embodiment 1, implement the above method in the single call process, such as Figure 14 shown, including steps:

[0081] 1401. The network side receives a service request sent by a first mobile terminal {MS(A)}, where the service request is a request from the first mobile terminal to establish a business relationship with a second mobile terminal {MS(B)};

[0082]1402. The network side notifies the second mobile terminal;

[0083] 1403. The network side receives confirmation response information from the second mobile terminal to the notification;

[0084] 1404. The network side notifies the first mobile terminal and the second mobile terminal to receive a frequency hopping synchronization information frame on a designated traffic channel, and sends the frequency hopping synchronization information to the first mobile terminal and the second mobile terminal 2. Mobile terminal.

[0085] In a further embodiment, the method further includes the step: 1405. The network s...

Embodiment 2

[0094] Embodiment 2, implementing the above method in the group call process, such as Figure 15 shown, including steps:

[0095] 1501. The network side receives a service request sent by a third mobile terminal that is a member of a talk group, where the service request is a request from the third mobile terminal to establish a business relationship with a fourth mobile terminal;

[0096] 1502. The network side broadcasts a notification message, informing the third mobile terminal and the fourth mobile terminal, which are members of the talk group, to receive the frequency hopping synchronization information frame on a designated traffic channel;

[0097] 1503. The network side switches to the traffic channel and sends the frequency hopping synchronization information frame to the third mobile terminal and the fourth mobile terminal.

[0098] In a further embodiment, in order to realize the insertion of a group call, that is, a member who is not a member of the talk group bu...

Abstract

The invention relates to the field of communication and provides a cluster communication method and a network side device. The method comprises the following step: in frequency-hopping synchronization of the cluster communication, a frequency-hopping synchronization information frame which comprises frequency-hopping synchronization information is sent to a mobile terminal which needs communication. As the frequency-hopping synchronization information is sent in a way combining a synchronization prefix method and an independent channel method, the sent synchronization information is abundant; the synchronization establishing time is short, and simultaneously, the format of the sent synchronization information adopts a TOD format which is similar to the synchronization prefix method, thus leading to certain confidentiality; and moreover, the cluster system sends the frequency-hopping synchronization information in an independent traffic channel, and therefore, the realizing technical difficulty is not high.

Description

technical field [0001] The present invention relates to the communication field, more specifically, to a trunking communication method and network side equipment in a digital trunking system. Background technique [0002] The trunking communication system refers to a dedicated mobile communication system in which multiple users share a group of radio channels and dynamically use these channels, and is mainly used for command and dispatch communication. The trunking communication system includes an analog trunking communication system and a digital trunking communication system, and a DMR trunking communication system based on a DMR (Digital Mobile Radio, digital mobile radio) trunking protocol is a digital trunking communication system. The current trunking communication system has the disadvantages of low channel utilization, low system capacity, and poor anti-interference performance. [0003] Frequency hopping communication technology refers to the communication technolo...
