摘要： A method and system are provided for optimal routing of calls in an Internet Protocol-based Base Station System (IP-based BSS) (200), whereby a plurality of new messages are introduced on the A-interface. One such message informs the BSS (200) that the Circuit Identity Codes (CICs) included in the message can be connected to the BSS (200) to provide optimal routing of one or more calls. Another such message informs the BSS (200) 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.

摘要： A packet-switched Base Station System (200) transmission infrastructure is disclosed, whereby statistical multiplexing can be used to improve the utilization of installed transmission resources. In such a packet-based network, all types of traffic (e.g., signalling, speech, Circuit-Switched Data and GPRS traffic) can be mixed because efficient mechanisms are made available for assuring that Quality of Service requirements are met. As such, the mixing of speech and data traffic with their different Quality of Service requirements is made especially efficient by the infrastructure (200) disclosed. Notably, the infrastructure (200) disclosed can be implemented for any Internet Protocol-(IP-)based Random Access Network (RAN), and in particular (but not exclusively), can be implemented for TDMA and Code Division Multiple Access (CDMA) systems.
