Problems solved by technology

In the current technology, it is necessary to manually identify reserved cells. Manually identifying reserved cells requires knowing the relationship between neighboring cells, complex network planning in advance, and the possibility of missing identification. When there are multiple MBSFN areas, manual identification of reserved cells is more convenient. complex

Abstract

Disclosed are an interference avoidance method and device. The interference avoidance method comprises: acquiring a cell list, an adjacent cell relationship of a cell and inter-cell interference information which are reported by a base station in an MBSFN region and a base station in a non-MBSFN region; according to the cell list, the adjacent cell relationship of the cell and the inter-cell interference information, and in conjunction with pre-set belonging relationship information about the cell and the MBSFN region, determining a reserved cell in the MBSFN region, wherein other cells except for the reserved cell in the MBSFN region are broadcast transmission cells; receiving an eMBMS session request sent by an MME; and sending a first session indication to a base station of the reserved cell, wherein the first session indication is used for indicating the base station of the reserved cell: for the reserved cell, no eMBMS service is performed on a time frequency resource occupied by the broadcast transmission cells or a unicast service is performed using a power less than a pre-set power. The embodiments of the present invention can automatically recognize a reserved cell and reduce interference.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an interference avoidance method and device. Background technique [0002] In traditional technologies, the wireless access network provides point-to-point unicast bearer services, supporting upper-layer user services such as file download and stream transmission, but unicast bearer services cannot share wireless and transmission resources of the access network. With the rapid development of smartphone users, the traffic generated by mobile video services and app store downloads is increasing rapidly. Even Long Term Evolution (LTE) networks inevitably have the risk of congestion. On the one hand, the service experience of users There has been a decline. On the other hand, operators are faced with the dilemma of increasing revenue without increasing revenue. For this reason, the Multimedia Broadcast Multicast Service (MBMS) has been introduced on the mobile network...
