Problems solved by technology

[0006] The LTE system only supports single-cell point-to-point transmission, and in the trunking communication system, there may be a large number of called UEs in a specific group in the cell. The called UE allocates dedicated transmission resources, resulting in a waste of air interface resources

Embodiment 1

[0031] In the trunking communication application scenario, in order to improve the utilization rate of air interface resources and make full use of the high-bandwidth performance advantages of the LTE system, the embodiment of the present invention proposes a method based on the LTE system to realize single-cell point-to-multipoint data transmission, and solves the problem of In the trunking communication system based on TD-LTE (Time Division-Long Time Evolution, Time Division Long-Term Evolution) technology (by enhancing the TD-LTE system to meet the requirements of the trunking service for the bearer network), the air interface adopts single-cell point-to-point When transmitting data at multiple points, how does the base station equipment configure the configuration information of the group call session to the target UE, and how the target UE receives downlink control and user plane data according to the configuration information.

[0032] In the embodiment of the present inv...

Embodiment 2

[0066] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a base station device, such as Figure 6 As shown, the base station equipment includes:

[0067] Assignment module 11, is used for in the process of starting a group call session, assigns the group call temporary identification for the called group;

[0068] The sending module 12 is configured to send the group call temporary identifier and the non-access stratum NAS layer group identifier corresponding to the called group during the group call session start process.

[0069] The sending module 12 is specifically configured to broadcast the group call dedicated paging cycle and paging time corresponding to the called group through system broadcast information; and,

[0070] According to the group paging cycle and paging time, the user equipment in the called group is paged through a paging message, and the paging message carries the group corresponding to the c...

Embodiment 3

[0078] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a user equipment, such as Figure 7As shown, the user equipment includes:

[0079] The receiving module 21 is configured to receive the group call temporary identifier and the non-access stratum NAS layer group identifier corresponding to the called group during the group call session initiation process;

Abstract

The invention discloses a method and a device for transmitting group call conversation information. The method comprises the steps that: during a beginning process of a group call conversation, a group call temporary identification is distributed for a called group by base station equipment; and the group call temporary identification and a corresponding non-access-layer NAS (Network Attached Storage) layer group identification of the called group are transmitted by the base station equipment. According to the method and the device for transmitting the group call conversation information which are disclosed by the embodiment of the invention, by adopting the advantage of a high bandwidth performance of an LTE (Long Term Evolution) system, the data transmission from a single neighborhood point to multi points is realized, the requirement on high use ratio of a hollow resource can be met under a trunking communication system, and thus the use ratio of the hollow resource can be increased.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and equipment for transmitting group call session information. Background technique [0002] The trunking communication system communicates in a half-duplex mode. During work, the acquisition and release of the channel is controlled by the PTT (Push To Talk) button. The channel utilization rate is high and the call connection is fast. At present, the trunking communication system has developed to the stage of broadband trunking communication system, relying on advanced wireless transmission technology (such as LTE (Long Term Evolution, Long Term Evolution)), to achieve a leap in various functions and technologies of the trunking communication system. The broadband trunking communication system supports diversified business types, diverse transmission methods, large bandwidth, and high transmission rate; the supported services include voice, data, video, etc...
