    摘要: Disclosed is a communication system for selecting a PLMN (Public Land Mobile Network). In the communication system, an MS (Mobile Station) transmits an MIN (Mobile Identification Number) message, an ESN (Electronic Serial Number) message and a location update request signal containing location information such that the MS's location can be registered, and searches for the PLMN on the basis of an HPLMN search period value corresponding to the location update request signal. An MSC (Mobile Switching Center) performs an authentication procedure for the MS transmitting the location update request signal, and extracts the location information from the location update request signal. A VLR (Visitor Location Register) stores subscriber data of the MS provided from outside the MS and registers a location of the MS. An HLR (Home Location Register) updates the location information of the MS extracted from the MSC, variably sets a search period value at a time of searching for an HPLMN or higher-priority PLMN on the basis of the location information of the MS, and transmits the set search period value to the MS.

    摘要: Disclosed is a method for managing extended neighbor cells of a mobile terminal designed to save power of a battery as well as search time at a visited location. The method is characterized by the steps of collecting information on cells which belong to neighboring different PLMN (Public Land Mobile Network) other than the PLMN to which a serving cell, which the mobile terminal is assigned to belongs, and of performing rescanning of HPLMN using the information on cells.

    摘要: A method and apparatus of performing an inter-PLMN (Public Land Mobile Network) cell reselection in a mobile communication terminal is disclosed. The invention includes checking whether system information including another PLMN BCCH (Broadcast Control CHannel) allocation list and an inter-PLMN cell reselection offset value is received and determining a reselection target cell using the received inter-PLMN cell reselection offset value when an inter-PLMN cell reselection is needed. Thus, network signaling caused by inter-PLMN location updating may be reduced.
