Embodiment 1

[0108] The inventor considers that the trunking communication system can be implemented based on the extension of the LTE architecture, that is, the LTE bearer establishment and management method is extended on the trunking communication system according to the characteristics of the cluster, so as to realize the establishment and management of the trunking bearer for the user with the right to speak, And the cluster bearer establishment and management of the multi-base station and multi-cell distribution of non-speaking users.

[0109] Based on the above idea, this embodiment provides a trunking system, which is extended on the existing LTE system architecture and combined with a dedicated trunking system to realize a trunking communication system, and which can realize simultaneous online broadband trunking communication of one or more services. Specifically, the information group system mainly consists of a trunk core network (Trunk Evolved Packet Core, referred to as T-EPC)...

Embodiment 2

[0114] This embodiment introduces a cluster core network device (T-EPC), which can be used in the cluster system provided in Embodiment 1 above. Specifically, the T-EPC includes at least a first module and a second module.

[0115] The first module judges whether a certain service satisfies the bearer establishment condition;

[0116] Specifically, when any of the following situations occurs, the first module judges that the service satisfies the bearer establishment condition.

[0117] The call-initiating user initiates a group call request, and the group call meets the bearer establishment conditions;

[0118] The trunking core network device directly dispatches a trunking call request, and the trunking call meets the bearer establishment condition;

[0119] The non-speaking user accesses the trunking call through a paging response, and establishes a wireless bearer for the non-speaking user for the first time, and the trunking call meets the bearer establishment condition...

Embodiment 3

[0136] This embodiment introduces a trunking base station (T-eNB), which can also be applied to the trunking system provided in Embodiment 1 above. Specifically, the T-eNB includes a first module and a second module.

[0137] The first module receives the context initialization establishment request sent by the cluster core network, and establishes the initialization context according to the T-RAB information that needs to be initialized;

[0138] The second module, after the establishment of the initialization context of the first module, sends the established radio bearer information to the cluster terminal that initiates the service through a configuration message, and notifies the cluster core network of the establishment result.

[0139] Among them, the first module establishes the initialization context according to the received context initialization establishment request, and the second module sends the established radio bearer information to the cluster terminal that ...

Abstract

The invention discloses a piece of trunk evolved packet core (T-EPC) equipment, a trunk E-UTRAN Node B (T-eNB) and an establishing method of a trunk bearer, which relate to broadband trunk communication systems based on LTE technology. The method comprises: when a service satisfies bearer establishing conditions, a T-EPC issues a context initialization establishing request, which carries initialization establishing T-RAB information, to a T-eNB, where a piece of trunk user equipment (T-UE) initiating the service is located; the T-eNB establishes an initialized context according to the context initialization establishing request; and after the initialized context is established, the T-eNB sends established radio access bearer information via a configuration message to the T-UE initiating the service, and notifies the T-EPC about the establishment result. The invention also discloses a piece of T-EPC equipment and a T-eNB. According to the technical scheme, a trunk communication system extended from an LTE architecture is achieved, and an LTE bearer establishment and management method is extended to a trunk system.

Description

technical field [0001] The present invention relates to a broadband cluster communication system based on Long Term Evolution (LTE for short) technology, in particular to a technical solution for establishing and managing cluster bearer between a base station and a cluster network. Background technique [0002] Trunking communication technology is expanded with the development of mobile communication technology. It has experienced the development experience from analog trunking to digital trunking. At present, with the development of communication technology, broadband, high-speed, and business diversification have become the development of communication technology. trend. From 2G to 3G, the trunking technology has been well extended and applied, but due to technical defects, it has not been able to realize real-time synchronous online services such as voice and high-speed data. Now LTE-based communication technology, that is, 4G technology has gradually entered the applica...
