specific Embodiment approach 1

[0082] Specific implementation mode one: the following combination figure 1 This embodiment is described. The system for realizing dynamic allocation of broadband and narrowband resources based on the narrowband air interface described in this embodiment includes a converged base station 1 and a terminal 2, and information exchange between the converged base station 1 and the terminal 2 is carried out in a wireless manner;

[0083] The converged base station 1 includes a cluster base station controller 1-1, a plurality of PDT base station channel units 1-2 and a broadband service unit 1-3,

[0084] The cluster base station controller 1-1 controls multiple PDT base station channel units 1-2 and broadband service units 1-3, and the cluster base station controller 1-1 is formed by adding a broadband service control unit to the original PDT base station controller The controller is used to realize the management of broadband and narrowband resources, and the broadband service cont...

specific Embodiment approach 2

[0087]Specific implementation mode two: this implementation mode further explains implementation mode one, and the setting of cluster base station controller 1-1 described in this implementation mode is as follows:

[0088] Based on the PDT air interface standard signaling, the two SK reserved values ​​in the extended call establishment request signaling C_RAND are the visual single call service type IND_VD_SRV=1011 and the visual group call service type GRP_VD_SRV=1100;

[0089] Add signaling VD_AP, the signaling VD_AP follows the allocation channel signaling TV_GRANT and allocation channel signaling PV_GRANT, and the signaling VD_AP carries the parameters needed to establish a visual service or use broadband service units 1-3 to transmit voice parameters; use PDT Voice services implemented by base station channel unit 1-2 do not use VD_AP signaling;

[0090] When not using the PDT base station channel unit 1-2 to transmit voice, identify the speech right or visual speech rig...

specific Embodiment approach 3

[0093] Specific implementation mode three: this implementation mode further explains implementation mode two, and the structure of the VD_AP signaling described in this implementation mode is shown in the following table:

Abstract

A system and method for realizing dynamic allocation of broadband and narrowband resources based on a narrowband air interface belongs to the technical field of trunking communication. The present invention aims to solve the problems of slow response of call establishment and low utilization rate of broadband resources when PDT air interface short messages are used to carry control information in the existing service realization method of broadband and narrowband access integration. The system includes a converged base station and a terminal, and information exchange between the converged base station and the terminal is carried out wirelessly; the converged base station includes a cluster base station controller, multiple PDT base station channel units and broadband service units; methods include call establishment, call process control The broadband service unit is added to the original PDT base station, and the signaling interaction of the broadband and narrowband services is performed through the PDT air interface signaling extension to realize the dynamic allocation of broadband and narrowband resources. The invention is used to realize the dynamic allocation of broadband and narrowband resources.

Description

technical field [0001] The invention relates to a system and a method for realizing dynamic allocation of broadband and narrowband resources based on a narrowband air interface, and belongs to the technical field of trunking communication. Background technique [0002] The existing trunking communication system standards are all narrowband trunking communication systems, such as the land trunking radio system TETRA standard, the digital mobile wireless DMR standard and the police digital trunking PDT standard, etc., which cannot meet the needs of multimedia trunking services. Therefore, on the basis of the existing narrowband trunking communication system, it is an important means to realize broadband multimedia trunking services by adding broadband service units to integrate broadband and narrowband access. [0003] Supporting broadband multimedia trunking services is the development trend of trunking systems. However, the trunking system must first meet the demands of a l...
