Problems solved by technology

[0004] In FULL MOCN, when a mobile terminal in a connected state, such as a mobile terminal in Dedicated (dedicated) mode, Packet Transfer (packet transfer) mode, or Dual Transfer (two-way transmission) mode, if the mobile terminal switches from the first cell to the adjacent When the second cell is shared by multiple PLMNs, the core network equipment usually randomly designates a PLMN for the mobile terminal to switch over, but this may cause the mobile terminal to be switched to an unsuitable PLMN
For example: when the mobile terminal switches from the first cell to the adjacent second cell, if the second cell is shared by PLMN1 and PLMN2, and the tariff of the mobile terminal under PLMN1 is cheaper than that under PLMN2, according to the current method core Network equipment may switch mobile terminals to PLMN2

Abstract

An embodiment of the invention discloses a public land mobile network (PLMN) selection method. According to the PLMN selection method, when switching from a first cell to an adjacent second cell, a mobile terminal selects a preferable PLMN after the switchover to the second cell; and the mobile terminal sends ID information of the preferable PLMN to a base station controller of the first cell. The invention also discloses the mobile terminal, the base station controller and core network equipment. The PLMN selection method, the mobile terminal, the base station controller and the core network equipment can be used for reasonably determining the PLMN to be switched by the mobile terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for selecting a PLMN (Public Land Mobile Network, public land mobile network), a mobile terminal, a BSC (Base Station Controller, base station controller) and core network equipment. Background technique [0002] PLMN is a network established and operated by the government or its approved operator for the purpose of providing land mobile communication services to the public; the network must be interconnected with PSTN (Public Switched Telephone Network, public switched telephone network) to form the entire region Or a national-scale communication network; in mainland China, common PLMNs include: China Mobile, China Unicom and China Telecom. [0003] During the construction of the cell, in order to maximize the sharing of wireless resources and save the operator's cost, MOCN (Multi-Operator Core Network, multi-operator core network sharing) technology is intro...
