Method for transmitting public procedure information in long term evolution augmentation system and system thereof

Abstract

The invention discloses a method for transmitting public procedure information in a long term evolution augmentation system and a system thereof. The method comprises the following steps: a request node sends a public procedure request signaling comprising a source cell ID and a target cell ID, wherein the source cell ID and the target cell ID are respectively the appointed cell ID for the request node and the target node; an intermediate node determines the target node according to the target cell ID and transmits the signaling to the target node; the target node determines the information required by the request node according to the type of the public procedure request signaling, sends a responding signaling containing the source cell ID, the target cell ID and the corresponding information after obtaining the corresponding information, wherein the source cell ID and the target cell ID are respectively the target cell ID and source cell ID of the request signaling; and the middle node determines the request node according to the target cell ID and transmits the signaling to the request node. By using the technical scheme of the invention, the intermediate node can determine the destination route of the request signaling and a response signaling, and transmits the route to the destination.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for transmitting public process information in a long-term evolution enhanced system. Background technique [0002] After 3GPP's Long Term Evolution (LTE, Long Term Evolution) technology, the 3GPP organization continued to enhance the LTE solution. This enhanced technology is called LTE-A (LTE-Advanced) technology, that is, LTE-A is the LTE technology subsequent evolution. [0003] In the LTE-A technology, a relay node (RN, Relay Node) is added to the architecture of the access network. RN can be regarded as an extension of evolved base station (eNB), providing more economical coverage for the system. The RN is connected to the eNB through a wireless interface. It can enhance the coverage quality at the edge of the eNB coverage, and can also be deployed outside the eNB coverage area to expand the coverage range. [0004] figure 1 It is a schematic...

Problems solved by technology

However, there may be no direct X2 interface connection between adjacent nodes in the LTE-A system. For example, there is no direct X2 interface connection between RNs deployed under different DeNBs, and only through the DeNB directly connected to each RN, Even the eNB connected to the two DeNBs through the X2 interface acts as an intermediate node to transfer

Using the method of obtaining public process information in the existing LTE system, when information needs to be transferred between two nodes without direct X2 interface connection, due to the lack of routing information, the intermediate node forwarding the information cannot determine the request information sent by the requesting node. Therefore, the request signaling cannot be forwarded to the target node, and the response signaling sent by the target node cannot be further forwarded to the requesting node, which results in the communication between two nodes not directly connected by the X2 interface. The public process information cannot be transmitted, which affects the information sharing between nodes and the work efficiency of the system
