Problems solved by technology

[0008] (1) Only the link between a Backhaul UE and an eNB (evolved Node B, evolved base station) is supported as a backhaul link, and the capacity of the backhaul link is limited, even if it is expanded through CA (Carrier aggregation) The capacity of the backhaul link has many problems to be solved, and the equipment cost is relatively high;
[0009] (2) Under the condit

Embodiment Construction

[0139] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0140] Compared with the existing Mobile Relay technical solution of TYPE I Relay, which only supports the link between one Backhaul UE and one eNB as a backhaul link, the data transmission method and system of the present invention divides one Backhaul UE into multiple LTE wireless access network elements, corresponding to multiple LTE wireless access network elements, set up one or more eNBs, thus forming multiple backhaul links and expanding the capacity of the backhaul links; at the same time, in LTE An aggregation server is added between GW (i.e. LTE gateway) and various core network gateways (including LTE-MME, UMTS-RNC, GSM-BSC, etc.); therefore, between LTE w...

Abstract

The invention discloses a data transmission method, a relay node, a convergence server and a system, wherein the method comprises the steps of: 1) establishing a plurality of tunnel connections between the relay node and the convergence server through a plurality of wireless access network elements; 2) conducting logical link control packaging on uplink IP groups uploaded by a mobile terminal through the relay node to form an uplink logical link control message; and 3) sending the uplink logical link control message to the convergence server by the relay node. The data transmission method, the relay node, the convergence server and the system has good compatibility and good extensibility, the RN (relay node) supports a plurality of LTE (Long Term Evolution) wireless access network elements, only a link application layer is corrected, only the convergence server is added, and an air interface protocol is not required to be corrected.

Description

technical field [0001] The present invention relates to wireless communication technology in the field of communication, in particular, to a data transmission method, a relay node, a convergence server and a system. Background technique [0002] In high-speed mobile environments such as high-speed railways and highways, providing high-quality and high-speed LTE (Long Term Evolution, Long Term Evolution) communication services and other 2G and 3G communication services for users in vehicles must solve vehicle body penetration The impact of loss. In order to overcome the penetration loss of the car body, the existing technical solution is to introduce Backhaul UE (relay link user equipment) on the top of the high-speed train or high-speed car as the RN (Relay Node, relay node) device of the Mobile Relay. The LTE TYPE I Relay technical solution provides IP-based backhaul services for various types of base stations inside the car body. [0003] The Mobile Relay system architec...
