Why do we MUST consider "Mobility"?
"Mobility" directly impacts both traffic and signaling loads; either one can be a serious bottleneck in a wireless network
| • |
Users' "mobility" affects the dynamics of traffic load. |
| • |
Users' "mobility" results in a big portion of network signaling load. |
Therefore, "Mobility" is the key to network resource re-engineering, which can bring the following benefits to Mobile Operators:
| • |
Maximizing efficiency of network utilization. |
| • |
Better network planning for upgrade/expansion. |
| • |
Greater robustness in network QoS. |
| • |
Minimizing the risks of over-investment. |

How mobility affects wireless network?
| Factors |
| • |
Mobility and human behavior determines signaling and traffic dynamics. |
| • |
SMS and packet-switched bursty traffic pattern results in high mobility management overhead. |
| • |
High complexity and constraints of multi-generations, multi-band, and multi-verndor networks.
|
| Challenges to overcome |
| • |
Inter 2G/3G failures |
| • |
Switching load/failures |
| • |
Paging/Registration load |
| • |
Data Throughput |
| • |
Channel blocking |
| • |
NW inefficiency in Special events |
