Status information acquiring method and system for base station participating in relaying in relay network

Abstract

The invention provides status information acquiring method and system for a base station participating in relaying in a relay network. The method comprises the step that: a relay node feeds back self status information or the status information of user equipment (User Equipment) within the self coverage range to the base station participating in the relaying. The base station (DeNB, Donor eNB) participating in the relaying acquires the status information of the RN side and the UE side of a Uu interface through the status information of the relay node (RN), fed back on the Un interface, thereby flexibly scheduling the UE or the E-RAB (E-Radio Access Bearer) of the UE and ensuring that each UE or the E-RAB of the UE can reasonably receive data sent by the DeNB, or the status of the RN or the E-RAB of the RN is controlled, and the overload condition is avoided happening on the RN through flow control.

Description

technical field [0001] The invention relates to a relay technology, in particular to a method and a system for obtaining state information by a base station participating in the relay in a relay network. Background technique [0002] figure 1 It is a schematic diagram of the composition structure of the existing cellular wireless communication system, such as figure 1 As shown, the cellular wireless communication system is mainly composed of a terminal, a radio access network (RAN, Radio Access Network) and a core network. RAN is composed of base stations, or base stations and base station controllers ( figure 1 The network composed of not shown in ) is responsible for access layer affairs, such as management of radio resources. There may be physical or logical connections between base stations according to the actual situation, such as figure 1 Base station 1 and base station 2, or base station 1 and base station 3 in . Each base station can be connected to one or more...

Problems solved by technology

If there is a service with a high priority and the wireless condition of the corresponding UE is very poor at this time, the DeNB will still give priority to the service with a high priority. In this way, the DeNB cannot perform traffic control reasonably, which will inevitably lead to the failure of the Un interface. low efficiency, or affect the transmission of other UEs or other services multiplexed on the same RN E-RAB, or even cause congestion or packet loss
