"The solution allows encapsulating the generated packet data within GTP headers and transmitting through the gateway points such as SGSN & GGSN, or SGW & PGW.
PCU through the Gb interface with the SGSN connection.
The integrated network comprises the primary architectural elements: a mobile station, three stationary stations, one Node B, one AP, a HLR, a GGSN, a SGSN and a RNC.
The AGTP resides in the GGSN and it communicates with the existing standard GTP-c module of the EGSN, SGSN and GGSN.
Upon the receipt of the authentication data request from the Visitor Location Register (VLR) / Serving GPRS Support Node (SGSN), The Home Location Register (HLR) / Authentication Centre (AuC) sends an authentication response back to the VLR/SGSN that contains an ordered array of n authentication vectors AV (1...n).
We now have full faith in the efficacy of the Internet-HSPA solution presented by Nokia Siemens Networks and are looking forward to a quick commercial deployment." The trial introduced a simple, flat architecture demonstrating how traffic can bypass the Radio Network Controller (RNC) and the Serving GPRS Support Node (SGSN),to deliver improved data transmission speeds.
Through RAP, TEMs (telecom equipment manufacturers) have access to integrated solutions that are ideal for carrier grade applications such as softswitches, SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node), RNC (Radio Network Controllers) and VoIP (voice over IP) gateways, among others.
The ATCA-715 is appropriate for wireless and wireline infrastructure designs for RNC, SGSN or Telco servers, as well as for central office servers.
For the GPRS, the GSM network is updated of the several nodes SGSN (Serving GPRS Support Node) and one GGSN (Gateway GPRS Support Node) through which the GPRS communicates using GTP (GPRS Tunneling Protocol) with external packet networks (PN), e.g.
