monitoring, at a network element configured to provide wireless voice and data communications in the wireless communication network, communication between the network element and one or more mobile stations in the wireless communication network without affecting performance of the monitored communication, the communication being monitored on a per call basis;
parsing data associated with the monitored communication into a plurality of call event messages each including a message type indicating at least one of a hand off trigger, a supplemental channel (SCH) characteristic, and an anchor characteristic;
storing the plurality of call event messages; and
performing an analysis on the stored call event messages by the network element, the analysis being based on the message type.
2. The method of claim 1 , wherein the monitoring step monitors communication at the network element and the network element is associated with at least one base station.
3. The method of claim 2 , wherein the network element includes at least one of a Mobile Switching Center, a Radio Network Controller, a Selection and Distribution Unit, a Base Station Controller, and a Packet Control Function.
4. The method of claim 1 , wherein the monitoring step monitors at least one of communication over a backhaul of the wireless communication network and monitoring communication over a chassis backplane of a network element.
5. The method of claim 1 , wherein the communication includes at least one of a signal between a base station and a mobile switch center and between a base station and a mobile station.
6. The method of claim 1 , wherein the storing step stores messages on a call-by-call basis.
7. The method of claim 6 , wherein the storing step stores a timestamp in association with the stored messages to indicate when the monitored communication associated with the data occurred.
8. The method of claim 6 , wherein the messages for a call includes a location of a mobile station involved in the call.
9. The method of claim 1 , wherein the stored messages are associated with at least one of a control message, a header of a traffic frames, an inter-base station soft-handoff control messages, a reverse mobile signaling message during soft-handoff and forward mobile signaling messages.
10. The method of claim 1 , wherein the SCH characteristic includes at least one of a supplemental channel setup, a supplemental channel denial, a supplemental channel abort, and a supplemental channel release.
11. The method of claim 1 , wherein the anchor characteristic includes at least one of an anchor setup, an anchor release and an anchor transfer.
12. The method of claim 1 , wherein the call event includes at least one of a normal end of a call, a call failure, and a handoff state change.
13. The method of claim 1 , wherein the storing step stores data associated with the messages on a periodic basis.
14. The method of claim 13 , wherein the periodic data is based on communication between a base station and a mobile switching center.
15. The method of claim 13 , wherein the periodic data relates to at least one of resource loading, operation, administration and maintenance.
16. The method of claim 1 , wherein the analysis includes aggregating a portion of the stored messages over time.
17. The method of claim 16 , wherein the analysis includes mobile location and propagation loss analysis.
18. The method of claim 16 , wherein the analysis includes a temporal correlation.
19. The method of claim 16 , wherein the analysis is performed on a per-call basis.
20. The method of claim 16 , wherein the analysis is performed on a time basis.
21. The method of claim 16 , wherein the analysis is performed on a user basis.
22. The method of claim 1 , wherein the wireless communication network includes at least one of Second Generation (2G), Third Generation (3G), Third-Generation, 144 kbps Wireless Technology (3G-1X), Fourth Generation (4G), Evolution-Data Optimized (EV-DO), Evolution-Data/Voice (EV-DV), Universal Mobile Telecommunications System (UMTS), and High-Speed Downlink Packet Access (HSDPA).
23. The method of claim 1 , wherein the wireless communication network includes at least one of 802.11b, 802,11a, 802.11g, Bluetooth and RF.
24. The method of claim 1 , wherein the wireless communication network includes an architecture being one of a flat architecture, a centralized architecture, and a combination of a flat architecture and a centralized architecture.
25. The method of claim 24 , wherein the centralized architecture includes an mobile switching center and a base station.
26. The method of claim 24 , wherein the flat architecture includes a base station router.
