Embodiment 1

[0029] see figure 1 , which is a schematic structural view of an embodiment of a DMR (Digital Mobile Radio) base station of the present invention, the DMR base station 10 is applied in a broadband multimedia trunking system, and includes at least one DMR-CHU101 (Digital Mobile Radio Channel Unit , Digital Mobile Radio-Channel Unit), a MSU102 (Medium-speed Service Unit, Medium-speed Service Unit) and a RANC103 (Radio Access Network Controller, Radio Access Network Controller), wherein, the DMR-CHU101 and the MSU102 occupies different channel resources;

[0030] The at least one DMR-CHU101 is used to communicate with the RANC103, forward the uplink service control signaling and DMR narrowband data to the RANC on the DMR channel allocated by the RANC for the terminal, and transmit the downlink service control signaling and DMR narrowband data are sent to each terminal;

[0031] The MSU102 is configured to establish a medium-rate service transmission channel with the RANC103, fo...

Embodiment 2

[0047] This embodiment also provides a wireless access network, which is applied in a broadband multimedia trunking system, and includes at least one DMR base station described in the first embodiment.

[0048] As can be seen from the foregoing embodiments, the medium-rate service unit is further added to the existing DMR base station, and the added medium-rate service unit occupies different channel resources from the DMR-CHU in the existing DMR base station, so that The extended DMR base station can not only support DMR narrowband services, but also further support medium-rate services. In addition, expanding the function of the rate service control signaling during transmission on the DMR-CHU in the existing DMR base station does not affect the use of the DMR standard control signaling. The existing resources are utilized to the greatest extent, which is conducive to the smooth transition from the narrowband trunking system to the broadband multimedia trunking system.

Embodiment 3

[0050] see image 3 , which is a structural schematic diagram of an embodiment of a trunking communication system of the present invention, the system includes: at least one dual-mode mobile terminal 301 supporting DMR narrowband service and medium rate service, at least one RAN302 described in Embodiment 2 (wireless Access network, Radio Access Net), one SCC303 (Switching Control Center, Switch&Control Center) and at least one dispatching station 304.

[0051] Preferably, the RAN and the SCC implement user service registration and call control according to an extended SIP (Session Initiation Protocol, Session Initiation Protocol).

[0052] Among them, SIP is defined by IETF, an application layer control protocol based on IP.

[0053] Preferably, the RAN and the SCC realize access authentication and user data synchronization according to an extended diameter protocol.

[0054] Among them, the diameter protocol is adopted by the AAA working group of the IETF as the next-gener...

Abstract

The embodiment of the invention discloses a DMR (Digital Mobile Radio) base station, a radio access network and a broadband multimedia trunked communication system. The DMR base station comprises at least a DMR-CHU (DMR Channel Unit), an MSU (Medium-rate Service Unit) and a RANC (Radio Access Network Controller) all of which are applied to the broadband multimedia trunked communication system, wherein the DMR-CHU and the MSU occupy different channel resources; the DMR-CHU and the RANC communicate with each other and forward a service control signaling and DMR narrowband data to the RANC and / or a terminal; a medium-rate service transmission channel is built between the MSU and the RANC to forward the medium-rate service data to the RANC and / or the terminal; a medium-rate service transmission channel is built by the RANC to forward the medium-rate service data to the MSU and / or an SCC (Switching Control Center), allocate DMR channels and forward the service control signaling and the DMR narrowband data to the DMR-CHU and / or the SCC. According to the embodiment of the invention, the conventional DMR base station can be enlarged; and the enlarged DMR base station not only can support DMR narrowband services, but also can support the medium-rate services.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a DMR base station, a wireless access network and a broadband multimedia cluster communication system. Background technique [0002] The trunking communication system is a special command and dispatch mobile communication system, which is mainly used in the field of professional mobile communication. Different from ordinary mobile communication, the biggest feature of trunking communication is sharing resources, sharing costs, sharing channel equipment, wireless communication system with multi-purpose services and high-efficiency command and dispatch functions. The voice communication of the trunking communication system adopts the PTT (Push To Talk) button, which is connected in a push-to-talk manner. The called party can answer the call without picking up the phone, and the connection speed is fast, and it can support functions such as group calls. [0003] Curren...
