A serving GPRS support node (SGSN) is responsible for the delivery of data packets from and to the mobile stations within its geographical service area. Its tasks include packet routing and transfer, mobility management (attach/detach and location management), logical link management, and authentication and charging functions. The location register of the SGSN stores location information (e.g., current cell, current VLR) and user profiles (e.g., IMSI, address(es) used in the packet data network) of all GPRS users registered with this SGSN.
IPnexus™ CPC388: For telecom equipment manufacturers building/developing an SGSN based on standard CompactPCI® hardware, the CPC388 can be used as the SS7 link access product.
IPnexus™ CPC4400: Provides inter-connectivity between the individual functions within the chassis as well as gigabit uplinks to the packet switched network. Higher performance CPCI switches are presently being released. The IPnexus™ CPC5400 is an example with: 8 port 1+ Gbps Switch with PICMG 2.16 support.
MicroLegend® Signaling Blade: For companies' building/developing GPRS nodes based on standard CompactPCI hardware, the MicroLegend Signaling Blade can be used to fulfill the SS7/IP interworking function in the event signaling information is being transported over IP.
Host or Node CPUs: In a 6U CompactPCI 19” Telecoms System up to 19 Node CPUs may be used in a CPCI PICMG 2.16 system with up to two Fabric Switches.Thee can be configured for high-availability or dual redundancy. Node CPCI CPUs can be used to perform a wide variatey of functions, these may include: Software Signal Processing (instead of older custom DSP based solutions), Telecoms Soft Switching, Man-Machine Interfaces and Applications in general.
Example above illustrates the PP 100/01x - 6U CompactPCI, Pentium III-M 1.2+ GHz, 2 GB SDRAM, Dual Independant 1 Gbps Ethernet interfaces, with on-board graphics, many more features and a PMC site for extra I/O.
Typically, Host or Node CPUs could be any one of the following CompactPCI Single Board Computers from Concurrent Technologies (CCT):
