Abstract

As a mobile device moves from one location area to another, the mobile device detects the different location identifiers broadcast by the wireless network(s) in those locations areas. The mobile device stores the location identifier for the last location area in which the mobile device was located. By comparing a received location identifier to the stored location identifier, the mobile device determines if the mobile device has entered a new location area. If so, the mobile device sends a location update request. In one embodiment, if the location update request is for a location area to which access by the mobile device is restricted, the network sends a communication to the mobile device that triggers the mobile device to update a location identifier stored at the mobile device to the location identifier for the restricted location area so that the mobile can update the network after entering / selecting a different location area.

Description

technical field [0001] Example embodiments of the invention relate generally to wireless networks and roaming handling in restricted areas. Background technique [0002] Wireless networks provide coverage for mobile devices to communicate with wired / wireless communication networks. There are a variety of wireless networks operated by several different wireless service providers. The process of allowing a mobile device signed up to one wireless provider to communicate on another wireless provider's wireless network is called roaming. [0003] Wireless networks divide the coverage area into small geographic areas. In wireless networks following the GSM protocol, these areas are called location areas. When a mobile device travels from one location area to a new location area, the mobile device notifies the wireless network of the new location area of ​​the presence of the mobile device by performing a location update procedure. [0004] During a location update procedure, t...
