IP Private A-link Intelligent Multiplexer

Descriptions

 

IP Private A-link Intelligent Multiplexer (iPALIM) is an application server of the UltraWAVE soft switch system to connect the local Inter-Reach Office (IRO) network to Public Mobile Network (PLMN) via A-interface. It allows the IRO to perform as a self-contained GSM system or a virtual BSC of the PLMN, depending on the desired service and user type. iPALIM monitors the messages originated by a subscriber to determine his user type, and selects the optimal way to route the call.

 

iPALIM provides two types of services - private service and public service.

iPALIM routes calls of private users to the local MSC for local switching within the IRO network. The private users may also make calls to local PSTN or PBX if it is attainable.

For public users, iPALIM routes calls to the PLMN MSC, bypassing the IRO soft-switch. iPALIM makes IRO appears as a BSC to the PLMN MSC. iPALIM is transparent to the user and to the IRO MSC. Moving into and out of the IRO is seamless to the public user.
