Embodiment 1

[0017] figure 2 The flow chart of the data transmission method under the failure mode provided by Embodiment 1 of the present invention, this embodiment is applicable to the situation in the LTE system, and the method can be executed by the transmission system installed in the base station, wherein, in the LTE system The base station communicates with the core network, so as to transfer the data / signaling uploaded by the UE (terminal) to another UE through the base station and the core network, thus realizing communication between two UEs. Wherein, the base station can cover multiple cells, and the same base station communicates with the first terminal and the second terminal, where the first terminal and the second terminal can be located in the same cell, or belong to different cells. The first terminal and the second terminal include but are not limited to: mobile phones, tablet computers, walkie-talkies and other terminals that communicate based on the LTE system. The me...

Embodiment 2

[0031] Figure 4 It is a schematic structural diagram of a data transmission system in a failure mode provided by Embodiment 2 of the present invention. This embodiment is applicable to the case of an LTE system, and the system is installed in a base station. Among them, in the LTE system, the base station communicates with the core network, so as to transfer the data / signaling uploaded by the UE (terminal) to another UE through the base station and the core network, so as to realize the communication between two UEs. Wherein, the base station can cover multiple cells, and the same base station communicates with the first terminal and the second terminal, where the first terminal and the second terminal can be located in the same cell, or belong to different cells. The first terminal and the second terminal include but are not limited to: mobile phones, tablet computers, walkie-talkies and other terminals that communicate based on the LTE system. The system 1 specifically inc...

Abstract

The invention discloses a data transmission method and system in a failure mode. The data transmission method and system in the failure mode is applied to a base station, wherein a plurality of cells covered by the base station contain a first terminal and at least one second terminal communicating with the base station. The data transmission method in the failure mode comprises the following steps: detecting the communication situation between the base station and the core network; and transmitting the uplink information acquired from the first terminal to the downlink channel based on the MBMS mechanism when confirming that the base station enters the failure mode based on the detected communication situation, and sending to at least one second terminal. According to the invention, the base station can achieve ''weak transmission'' under the failure mode, therefore, the problem that the data transmission can not be carried out when the base station and the core network fail to communicate under the LTE standard can be effectively solved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a data transmission method and system in a failure mode. Background technique [0002] In the LTE standard, data communication between UEs (terminals) is performed through a base station and a core network for data forwarding. When a communication failure occurs between the base station and the core network, the base station cannot serve the UE. [0003] In addition, MBMS technology is characterized by network resource sharing, that is, by providing a point-to-multipoint data transmission mechanism, it can provide services for a large number of users with the same needs at the same time with less network resources, so that network resources can be shared. The network resource consumption of the MBMS technology has nothing to do with the growth of the number of users, so that limited air interface resources can be effectively saved. [0004] At present, the...
