Pre-configuration method and system of return trip link

Abstract

The invention discloses a pre-configuration method and a system of a return trip link. The pre-configuration method of the return trip link comprises an access point (AP) is accessed to a network as a terminal, reports self-ability and demands pre-configuration information, according to the self-ability reported by the AP, a target network point is selected for the AP by the network, the target network point is informed and conducts an acceptance preparation and feeds back the pre-configuration information to the AP, and the AP is accessed to the target network point according to the acquired pre-configuration information. The AP is accessed to the network as a terminal, according to the feedback pre-configuration information of the self-ability reported by the AP, a wireless return trip link is established on the free spectrum resources by the network, on the premise that communication quality of the target network point is ensured, the AP access success rate and conversation quality after access are improved, mutual interference between the wireless return trip link and an access link is avoided, and AP access time is saved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a backhaul link preconfiguration method and system. Background technique [0002] For a Long Term Evolution (LTE) system or a Long Term Evolution-advanced (LTE-A) system, the current Access Point (Access Point, AP) mainly includes: an enhanced macro cell base station ( enhanced Node Base Station), relay node (Relay Node, RN), pico cell base station (Femto NB), micro cell base station (Pico NB) and home base station (home NB). Some of these access nodes can be directly connected, and the link between the access nodes that can be directly connected is called a backhaul link (backhaul link). [0003] Taking RN as an example, the so-called relay technology, simply put, is that in the downlink direction, the signal sent by the base station to the terminal is not directly sent to the terminal, but first sent to an RN, and then forwarded to the terminal by the RN; in the u...

AI Technical Summary

Problems solved by technology

In this allocation method, the spectrum resource reused by the backhaul link and the access link will inevitably cause mutual interference between the two links, and to a certain extent, it will also affect the current base station connected to the AP. impact on the capacity and quality of service of the access link
