Problems solved by technology

[0010] 1. The modification and negotiation process of mobility parameters (including handover parameters and cell reselection parameters) is generally completed through the X2 interface. When negotiating mobility parameters between systems, since there is no X2 interface between systems, it cannot be performed through the X2 interface. Negotiation of mobility parameters; in addition, when there is no X2 interface between eNBs, the negotiation of mobility parameters cannot be performed through the X2 interface;
[0011] 2. When negotiating mobility parameters without obtaining the mobility parameters (including cell reselection and handover parameters) of the opposite cell, only the mobility parameter configuration of the own cell can be carried first, and it needs to be carried out during the negotiation process. The acquisition of the mobility parameter configuration of the opposite cell increases the signaling processing flow of the negotiation process, making the implementation of the negotiation process more complicated

Abstract

The invention discloses mobile parameter enquiry and negotiation method and system. The negotiation method comprises the following steps that: a source base station control entity sends a mobile parameter change request to a target base station control entity through a transmission entity, wherein the mobile parameter change request contains mobile parameter change configuration of a source cell attached to the source base station control entity and / or a target cell attached to the target base station control entity; after the target base station control entity receives the change request, the target base station control entity feeds back a mobile parameter change response message to the source base station control entity through the transmission entity if accepting the change configuration in the change request; and after receiving the mobile parameter change response message, the source base station control entity changes the mobile parameter of the source cell. By using the method disclosed by the invention, the negotiation process can be optimized, and proper mobile parameter configuration can be performed.

Description

technical field [0001] The present invention relates to the technical field of wireless cellular communication, and more specifically, to a method / system for querying and negotiating mobility parameters. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) network consists of an E-UTRAN (Evolved UTRAN) base station (Evolved NodeB, eNB for short) and an evolved packet switching center (Evolved Packet Core, EPC for short), and the network is flat. like figure 1 As shown in , the EPC includes a Mobility Management Entity (MME for short) and a Serving Gateway (S-GW for short). The E-UTRAN includes a collection of eNBs connected to the EPC through the S1 interface, and the eNBs can be connected through the X2. S1 and X2 are logical interfaces. One EPC can manage one or more eNBs, one eNB can also be controlled by multiple EPCs, one eNB can manage one or more cells (cells). [0003] Self Organizing Network (SON for short) is a technology for automat...
