A Base Station System (BSS) infrastructure is provided which is based on an IP or packet-based, connection-less protocol. Notably, the BSS disclosed can be implemented for any IP-based Radio Access Network, and in particular (but not exclusively), can be implemented for GSM and TDMA systems, including those with GPRS/EDGE applications.

IP-based base station system

The present invention is related to a method of configuring an interface between a serving GPRS support node and a base station system. A signal is transmitted () from the base station system to the serving GPRS support node indicating cancellation of at least one BSSGP virtual connection associated with a first network service entity identifier. Upon receipt of the cancellation signal at the serving GPRS support node, data structures in the serving GPRS support node are updated () to reflect that the at least one BSSGP virtual connection has been cancelled.

Method in a communication network

The present invention is related to a method of configuring an interface between a serving GPRS support node and a base station system. Allocation (,) of a new network service entitiy identifier is requested. In response to said request, a new network service entity identifier is automatically allocated (,) according to a predefined rule ensuring that the new network service entity identifier is unique within the serving GPRS support node. Data structures in the serving GPRS support node and the base station system are automatically initiated (,) by registering the allocated new network service entity identifier in said data structures.

An improved method and apparatus for transmitting data between a transceiver and transcoder pair of a cellular radio system is disclosed. A pair of transceiver-transcoder-links normally transmitted on two separate channels are broken into a series of four bit data segments which are multiplexed together into series of eight bit timeslots for transmission between a transceiver and a transcoder pair.
