Gsm location update frequency

Periodic location update is carried out when the network does not receive any location update request from the mobile in a specified time. Such a situation is created when a mobile is switched on but no traffic is carried, in which case the mobile is only reading and measuring the information sent by the network. If the subscriber is moving within a single location area, there is no need to send a location update request.

A timer controls the periodic updates and the operator of the VLR sets the timer value. The network broadcasts this timer value so that a mobile station knows the periodic location update timer values. Therefore, when the set time is up, the mobile station initiates a registration process by sending a location update request signal.

The VLR receives the request and confirms the registration of the mobile in the same location area. If the mobile station does not follow this procedure, it could be that the batteries of the mobile are exhausted or the subscriber is in an area where there is no network coverage.

A mobile phone in motion keeps the network informed about changes in the location area. The GSM mobile measures the cell strength to see if it should change its primary cell. The BCCH of the neighboring cells is monitored to determine if any of the neighbors have a better signal strength Signal Comparison Whenever the primary cell changes, the mobile checks if the Location area of the old cell and the new cell are different. If the old and new location areas are different. The mobile initiates the Location Area Update procedure.

The signaling for location updating, type IMSI attach is identical to normal location updating, except for some bits in the message Location Updating Request that indicate the type of updating.

Authentication is optional in this case. The MS is informed via the system information if periodic registration is used in the cell. If periodic registration is used, the MS is told how often it must register. The time is set by the operator and can have values from 0 to decide hours a unit of six minutes. If the parameter is equal to zero, periodic registration is not used in this cell. If the parameter is set to ten, for example, the MS must register every hour. When the timer in the MS expires, the MS performs a location updating, type periodic registration.

If the MS does not register within the determined interval plus a guard time, then the scanning function in MSC detects this and the MS is flagged as detached. Teresa Wells Dec. Soud Said Jun. Ashish Kumar Mar. Deepak Prasad Mar.
