IMSI attach In a GSM network, when a Mobile Station MS is switched on, the International Mobile Subscriber Identity IMSI attach procedure is executed. This procedure is required for the Mobile Switching Center MSC and Visitor Location Register VLR to register the MS in the network. If the MS has changed Mobility management Location area Location area LA while it was powered off the IMSI attach procedure will lead to a Location update Location update . When the MS is switched on, it searches for a mobile network to connect to. Once the MS identifies its desired network, it sends a message to the network to indicate that it has entered into an idle state. The Visitor Location Register VLR checks its database to determine whether there is an existing record of the particular subscriber. br If no record is found, the VLR communicates with the subscriber s Home Location Register HLR and obtains a copy of the subscription information. The obtained information is stored in the database of the VLR. Then an acknowledge message is sent to the MS. IMSI detach IMSI detach is the process of detaching a MS from the mobile network to which it was connected. The IMSI detach procedure informs the network that the Mobile Station is switched off or is unreachable. At power down the MS requests a signaling channel. Once assigned, the MS sends an IMSI detach message to the VLR. When the VLR receives the IMSI detach message, the corresponding IMSI is marked as detached by setting the IMSI detach flag. The HLR is not informed of this and the VLR does not acknowledge the MS about the IMSI detach. br ... to send IMSI detach messages. Therefore the GSM network considers the MS to be still attached.

The GSM Interworking Profile , usually abbreviated to GIP and sometimes to IWP, is a profile for DECT that allows a DECT base station to form part of a GSM network, given suitable handsets. While proposed and tested, notably in Switzerland in 1995, the system has never been commercially deployed. Infrastructure issues make it less practical and useful to implement than the more recent Generic Access Network GAN UMA system, which can make use of usually unmetered and neutral Internet service to provide the connection back to the network operator. Description Like the later Generic Access Network GAN UMA standard, GIP makes use of a technology that doesn t require licensed spectrum to expand capacity and allow end users, in theory, to improve coverage in areas difficult to reach via large, external, cell towers.
