Problems solved by technology

The traditional implementation method is to use incremental development on the base station. Although the cluster service failure weakening function can be realized, the functional workload of developing the core network is heavy and the logic complexity is high, which leads to an increase in the cost of developing software and hardware. The cost-effectiveness of the solution not tall

Embodiment 1

[0017] This embodiment adopts the same uplink / downlink bearer ID as the data forwarding rule in the fault weakening mode, that is, the user plane of the base station directly forwards the data of the uplink bearer to the bearer with the same downlink bearer ID.

[0018] In order to realize that in the fault weakening mode, the downlink bearer ID of the established trunking service is consistent with the uplink bearer ID, the base station, during the signaling interaction process of the trunking service establishment, such as figure 2 As shown, the following business establishment process is adopted:

[0019] (1) In the fault weakening mode, the cluster terminal initiates a cluster service;

[0020] (2) After receiving the cluster service establishment request, the base station first establishes the bearer of the downlink service channel;

[0021] (3) After receiving the establishment response message of the bearer of the downlink traffic channel, the base station obtains the...

Embodiment 2

[0025] In this embodiment, in the fault weakening mode, the establishment of a mapping relationship table for uplink and downlink bearer forwarding is used to forward service data. forwarding.

[0026] In order to realize the forwarding and mapping relationship of the uplink and downlink service data during the cluster service establishment process of the base station in the fault weakening mode, the base station, during the signaling interaction process of the cluster service establishment, such as image 3 As shown, the following business establishment process is adopted:

[0027] (1) In the fault weakening mode, the cluster terminal initiates a cluster service;

[0028] (2) After receiving the trunking service establishment request, the base station establishes the bearer of the uplink / downlink service channel;

[0029] (3) The base station establishes a mapping relationship table for forwarding uplink and downlink data of the trunking service according to the bearer ID o...

Abstract

The invention provides a method for supporting fail soft of a cluster service of an LTE network. The method comprises the following steps of establishing an uplink and downlink data loopback forwarding rule of the cluster service in a base station in a process of establishing the cluster service; and directly forwarding uplink and downlink bearer data of the cluster service to a downlink bearer in the base station according to the loopback forwarding rule.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for supporting cluster service failure weakening in an LTE network. Background technique [0002] Weakening of cluster business failures, such as figure 1 As shown, it means that when a failure occurs between the core network and the base station or within the core network, the base station can provide limited trunking services to users within its coverage. When the base station enters the fault weakening mode, the base station notifies the users in the cell through a system message, and the base station enters the fault weakening working mode. When the base station detects that the link with the core network is back to normal, the base station switches to the normal working mode, and at the same time notifies the terminal to switch to the normal mode in a system message. For cluster terminals, the fault weakening mode is the same as the normal mode in terms of se...
