Abstract

The present invention relates to the detection by a mobile device of different location identifiers broadcast by a wireless network in those location areas as the mobile device moves from one location area to another. The mobile device stores the location identifier of the last location area in which the mobile device was located. By comparing the received location identifier with the stored location designator, the mobile device determines whether the mobile device has entered a new location area. If yes, the mobile device sends a location update request. In one embodiment, if the location update request is for a restricted location area of ​​the mobile device, the network sends information to the mobile device that triggers the mobile device to update the location identifier stored on the mobile device to a restricted location The location identifier of the area so that the mobile can update the network after entering / selecting a different location area.

Description

Technical field [0001] Example embodiments of the present invention generally involve roaming processing in wireless networks and restricted areas. Background technique [0002] The wireless network provides coverage for mobile devices to communicate with wired / wireless communication networks. There are multiple wireless networks operated by multiple different wireless service providers. The process of allowing mobile devices contracted by one wireless provider to communicate on another wireless provider's wireless network is called roaming. [0003] The wireless network divides the coverage area into multiple small geographic areas. In a wireless network that complies with the GSM protocol, these areas are called location areas. When the mobile device travels from a location area to a new location area, the mobile device notifies the wireless network of the new location area of ​​the existence of the mobile device by performing a location update process. [0004] In the location...
