Abstract

A mobile node registers with a wireless telecommunications network to obtain a mobile node registration having a registration time period. Before the registration time period expires, the mobile node'"'"'s registration is renewed, if a renewal criterion is met. The renewal criterion distinguishes between user data traffic and automatic data traffic.

Claims

1. A method of registration management for a mobile node, said mobile node transmitting and receiving packet data traffic, said method comprising:

registering said mobile node with a wireless telecommunications network to obtain a mobile node registration, said mobile node registration having a registration time period;

obtaining a packet data traffic amount by determining how much packet data traffic, exclusive of packet data traffic satisfying at least one exclusion criterion, occurred within a predetermined time period; and

renewing said mobile node registration if said packet data traffic amount is at least a predetermined amount.

2. The method of claim 1, wherein said at least one exclusion criterion distinguishes between automatic packet data traffic and user packet data traffic.

3. The method of claim 1, wherein packet data traffic satisfies said at least one exclusion criterion by occurring during an exclusion time period.

4. The method of claim 1, wherein packet data traffic satisfies said at least one exclusion criterion by having at least one packet characteristic.

5. The method of claim 1, wherein said predetermined time period is a sampling window within said registration time period.
