Abstract: 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?-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.

Abstract: A method and apparatus for reducing delay in the transmission of a plurality of packets by performing IP scheduling and header compression at various layers in a multilayer architecture having a plurality of classifications includes scheduling packets according to classifications. If congestion occurs during scheduling, packets may be discarded. Some packet headers may be compressed thereafter. Packets may further be queued in a first and a second queue, after scheduling, discarding, and compressing, according to at least two classifications. Best Efforts packets may be queued into the lower priority second queue. Classifications may be associated with, for example, QoS levels, delay factors, LFI, and Multilink PPP. Scheduling is performed at higher or lower layers in a multi-layer protocol. The lower layer includes a PPP layer. The lower layer may also include an HDLC layer which creates a tag for packets prior to compression being performed thereupon.
