Systems, methods, and apparatus for managing IP addresses and network traffic in wireless networks
First Claim
1. A method comprising:
- receiving, at an electronic communication device, a plurality of network addresses from a network, each network address having an associated timer and an associated data traffic channel; and
transmitting, from the electronic communication device to the network, a consolidated keep-alive message identifying two or more network addresses of the plurality of network addresses, the consolidated keep alive message causing a refresh of the timers associated with each of the two or more network addresses, each network address identifying a different device providing a service via an associated data traffic channel to the electronic communication device, wherein said transmitting occurs at a point in time nearest to a timeout indicated by a timer associated with an identified network address having a lowest time remaining until timeout from amongst the timers for the identified network addresses.

Abstract
Systems, methods and apparatus described herein include features that enable efficient management of keep-alive messages utilized to maintain IP addresses and/or PDN connections associated with idle data traffic channels. An access terminal may consolidate keep-alive messages for idle data traffic channels, reducing the number of keep-alive messages transmitted. An access terminal may select which idle data traffic channels to maintain, and may transmit a consolidated keep-alive message for associated IP addresses and/or PDN connections. Timers may be associated with PDN connections and sub-timers may be associated with IP addresses associated with a PDN connection. Keep-alive messages can be consolidated based on the timers, sub-timers and/or combination of timers and sub-timers. In a complementary method, a PDN gateway or other network node cooperates with access terminals to reduce network traffic. In another complementary method, the PDN gateway or other network node synchronizes the timers and/or sub-timers provided with an access terminal.

13. An apparatus comprising:
-
means for receiving a plurality of network addresses from a network, each network address having an associated timer and an associated data traffic channel; and means for transmitting, to the network, a consolidated keep-alive message identifying two or more network addresses of the plurality of network addresses, the consolidated keep alive message causing a refresh of the timers associated with each of the two or more network addresses, each network address identifying a different device providing a service via an associated data traffic channel to the apparatus, wherein said transmitting occurs at a point in time nearest to a timeout indicated by a timer associated with an identified network address having a lowest time remaining until timeout from amongst the timers for the identified network addresses. - View Dependent Claims (14, 15, 16, 17, 18)

19. A non-transitory computer readable medium comprising instructions that when executed cause an apparatus to:
-
receive a plurality of network addresses from a network, each network address having an associated timer and an associated data traffic channel; and transmit, to the network, a consolidated keep-alive message identifying two or more network addresses of the plurality of network addresses, the consolidated keep alive message causing a refresh of the timers associated with each of the two or more network addresses, each network address identifying a different device providing a service via an associated data traffic channel to the apparatus, wherein said transmitting occurs at a point in time nearest to a timeout indicated by a timer associated with an identified network address having a lowest time remaining until timeout from amongst the timers for the identified network addresses. - View Dependent Claims (20, 21)
