1. A method for optimal routing of a call in a Base Station System, comprising the steps of:
- sending a message to said Base Station System, said message including information associated with a plurality of ports in an IP network;
ordering a first base transceiver station to send at least a first packet associated with said call to a second base transceiver station via at least a first port of said plurality of ports in said IP network; and
ordering said second base transceiver station to send at least a second packet associated with said call to said first base transceiver station via at least a second port of said plurality of ports in said IP network, further comprising the step of;
suspending a transfer of packets associated with said call from a gateway to said first base transceiver station and said second base transceiver station.

Abstract
A method and system are provided for optimal routing of calls in an Internet Protocol-based Base Station System (IP-based BSS), whereby a plurality of new messages are introduced on the A-interface. One such message informs the BSS that the Circuit Identity Codes (CICs) included in the message can be connected to the BSS to provide optimal routing of one or more calls. Another such message informs the BSS that the CICs included in the message are to be restored as separate CICs on the A-interface. The provision of such messages overcomes the significant disadvantages of the existing and developing BSS implementations.
