GPRS and EDGE

2. modulation used in EDGE
7. GPRS uses these unused channels for transportation of data in general
9. performs transcoding function for speech channels and RA for data channels in GSM
11. contains information about sender and receiver of packets
13. GSM uses this handoff
14. GPRS provides what mode of transfer?
17. static database that stores subscribed services
18. total number of classes in MSs
20. contains routing information for GPRS users
21. enhancement to existing GSM network
22. supports MS via the Gp interface
24. Channel request (packet) from MS to BSS
25. When the user wants to attach to the GPRS network, the mobile device enters this state as soon the first packet is sent

1. network providers charge for GPRS models based on what?
3. used to page a mobile prior to downlink packet transfer
4. a standard set of protocols enabling wireless web applications on a cell phone
5. all data within GPRS network is transferred using what protocol
6. number of coding schemes used to add redundancy to the user data
8. MS is not reachable in this mode
10. main characteristic of GPRS
12. also called 2.5G
15. interface that connects BTS with BSC
16. temporal identifier included in attachment process before sending data
19. can provide data rate upto 43.2Kbps using multiple slots simultaneously
20. modulation technique used in GPRS
21. interface between SGSN and GGSN
23. when no data is transferred for some time,the ready timer expires and the mobile device changes into this state
