A system and method in a General Packet Radio Service (GPRS) network for automatically configuring Network Service Entity Identifiers (NSEIs) in a Base Station System (BSS) and a Serving GPRS Support Node (SGSN) when the BSS is reconfigured. The Gb interface between the BSS and the SGSN is modified to operate using the Internet Protocol (IP), and the BSS and the SGSN are configured to run on IP. Whenever a new Network Service Entity (NSE) is added to an existing BSS, or a new BSS is added to the network, the BSS automatically sends a modified Network Service (NS')-Reset message to the SGSN requesting an NSEI. The SGSN dynamically allocates a free NSEI from a pool of NSEIs and sends it to the BSS. When an NSE is removed from the BSS, the BSS automatically sends a modified NS&#x2032;-Reset message to the SGSN to free an NSEI. The SGSN de-allocates the NSEI, and returns the NSEI to the pool of free NSEIs. All related entries for Base Station System GPRS Protocol (BSSGP) Virtual Circuit Identifiers (BVCIs) under the de-allocated NSEI are also removed by the SGSN.

System and method for automatically configuring network service entity identifiers utilizing a Gb-over-IP interface in a GPRS network

A method of preserving data packet sequencing between nodes in a radio telecommunications network in which the User Datagram Protocol/Internet Protocol (UDP/IP) is utilized to communicate between the nodes of the network. Sequencing numbers are added to the headers of a plurality of data packets which are transmitted over a plurality of data transmission paths. The UDP/IP protocol is adapted with a resequencing layer which is utilized at the receiving node to resequence the packets.

Method of preserving data packet sequencing

A system and method in a General Packet Radio Service (GPRS) network for interfacing a Base Station System (BSS) and a Serving GPRS Support Node (SGSN). A protocol stack in the BSS and the SGSN includes a User Datagram Protocol (UDP) layer over an Internet Protocol (IP) layer. Data packets are transmitted between functional entities in the SGSN and the BSS over a connectionless IP network. The protocol stack includes a Base Station System GPRS Protocol (BSSGP) protocol layer that provides radio-related, Quality-of-Service (QoS), and routing information that is required to transmit user data between the BSS and the SGSN. The stack also includes a modified Network Services (NS&prime;) layer which is divided into an upper NS&prime;-Network Service Control (NS&prime;-NSC) sub-layer and a lower NS&prime;-Sub-Network Service (NS&prime;-SNS) sub-layer. The NS&prime;-NSC sub-layer maps to the BSSGP layer and manages fictional entities therein. The NS&prime;-SNS sub-layer maps to the UDP and IP layers and provides access to the IP network. A single UDP port is reserved to make the NS layer and the BSSGP layer act as an application over the IP stack.
