Method, device and system for paging heterogeneous network

Abstract

The embodiment of the invention provides a method, a device and a system for paging a heterogeneous network, which belongs to the communication field. The method comprises the following steps: reporting an interference report to a base station in which an interfered cell resides when the condition of reporting interference is satisfied so that the base station in which the interfered cell resides can generate and send a paging configuration updating message according to the received interference report; and receiving the paging configuration updating message generated and sent by the base station in which the interfered cell resides, and updating the paging configuration to the paging configuration which can avoid the interference according to the paging configuration updating message. The invention further provides a terminal device, a communication device and a communication system. In the scene of the heterogeneous network, under the condition that the interfering cell configures is approximately configured with vacant sub-frame so as to ensure the load thereof and reduce the signaling overload on the interface at the rank of the cell (or base station), the interfered UE (User Equipment) in the interfered cell can also receive the paging message through the method.

Description

technical field [0001] The present invention relates to the communication field, in particular to a paging method, equipment and system for a heterogeneous network. Background technique [0002] In the current LTE (Long Term Evolution, long-term evolution) heterogeneous network, small base stations are placed within the coverage of the macro base station (Macro eNB), such as Pico, HeNB (Home eNB, home base station), Femto, Relay and other wireless access points , UE (User Equipment, user equipment (terminal)) is under the dual coverage of macro base stations and small base stations. The maximum capacity that this system can obtain is the sum of the capacities of macro base stations and small base stations. The station network has a higher capacity. In scenarios such as office buildings, shopping malls, and campus networks, the heterogeneous deployment of these small base stations and macro base stations can effectively enhance network coverage and improve spectrum efficienc...

Problems solved by technology

With this method, the setting of near-blank subframes in the offending cell will be limited by the PF and PO of each UE in the victim cell, and too many almost-blank subframe settings will affect the scheduling of the offending cell’s own UE, reducing the number of offending cells. own load and system capacity, and needs to transmit UE-level information on the communication interface of the offending cell and the victim cell, which increases signaling overhead
