Abstract

Methods and apparatus for switching nodes from a current packet data connection point to a new packet data connection point are provided. According to one embodiment of the invention, at least one group of nodes that are in communication with a network infrastructure using a first packet data connection point are identified (304) based, at least in part, on at least one predefined criterion. This group of selected nodes is then reestablished (306) using a second packet data connection point.

Claims

1. A method comprising:

identifying at least one group of nodes using a first packet data connection point based, at least in part, on at least one predefined criterion to provide at least one group of a plurality of selected nodes in communication with a network infrastructure;

reestablishing the at least one group of plurality of selected nodes using a second packet data connection point.

2. The method according to claim 1, wherein the at least one predefined criterion comprises one or more selected from a group of membership to an Internet Protocol subnet in a source network, connection to an Internet Protocol Gateway, membership in a multicast group, usage of a beam-forming antenna resource, usage of frequency resources of time-multiplex, usage of time and frequency resources, radio capable, geographical location, geographical proximity, at least one multimedia capability of a node, at least one radio connectivity capability of a node, service subscription, at least one quality of service preferences, at least one security level requirement, at least one battery resource, at least one energy resource, at least one software upgrade, at least one software reconfiguration, and at least one management instruction of a node.

3. The method according to claim 1, wherein the network infrastructure comprises one or more selected from a group of a wireless network, a radio network, a cellular network, a local area network, a distributed network, a mesh network, a push-to-talk network, a dispatch network, a telephony network, a broadcast network, an information technology network, a highway information network, a satellite network, a power grid network, and a security network.

4. The method according to claim 1, wherein identifying the at least one group of nodes is triggered by any one or more selected from a group of an overload of a current packet data connection, transmission flow of a higher priority packet, data content request in substantially same format as at least one node on the network infrastructure, a change in power level, a need for a node reconfiguration based, at least in part, on a diagnostic test, a need for a service reconfiguration based, at least in part, on a diagnostic test, and at least one driver update.

5. The method according to claim 1 further comprising:

sending a group identifier to identify the plurality of selected nodes belonging to the at least one group.

6. The method according to claim 1, wherein reestablishing the at least one group of plurality of selected nodes using a second packet data connection point further comprises:

sending a network address of the second packet data connection point to the plurality of selected nodes.

7. A method comprising:

receiving a new packet data connection point to change a current packet data connection point triggered by, at least in part, at least one predefined criterion;

switching the current packet data connection point to the new packet data connection point.

8. The method according to claim 7 further comprising:

receiving an indication to perform a switch of the current packet data connection point to the new packet data connection point

9. The method according to claim 7 further comprising:

receiving a group identifier to identify membership to a group of a plurality of selected nodes to be switched to the new packet data connection point.

10. The method according to claim 7 further comprising:

receiving a network address of the new packet data connection point.

11. The method according to claim 10, wherein receiving a network address of the new packet data connection point further comprises:

receiving a modified portion of a network address of the current packet data connection point.

12. The method according to claim 7 further comprising, prior to receiving a new packet data connection point to change a current packet data connection point triggered by, at least in part, at least one predefined criterion:

sending a request to switch from the current packet data connection point.

13. The method according to claim 7, wherein the predefined criterion comprises one or more selected from a group of membership to an Internet Protocol subnet in a source network, connection to an Internet Protocol Gateway, membership in a multicast group, usage of a beam-forming antenna resource, usage of frequency resources of time-multiplex, usage of time and frequency resource, radio capable, geographical location, geographical proximity, at least one multimedia capability of a node, at least one radio connectivity capability of a node, service subscription, at least one quality of service preferences, at least one security level requirement, at least one battery resource, at least one energy resource, at least one software upgrade, at least one software reconfiguration, and at least one management instruction of a node.

14. The method according to claim 7, wherein the network infrastructure comprises one or more selected from a group of a wireless network, a radio network, a cellular network, a local area network, a distributed network, a mesh network, a push-to-talk network, a dispatch network, a telephony network, a broadcast network, an information technology network, a highway information network, a satellite network, a power grid network, and a security network.

15. An apparatus comprising:

a memory circuit having information corresponding to a predefined criterion stored therein;

a controller circuit operably coupled to the memory and that identifies at least one group of nodes using a first packet data connection point based, at least in part, on the predefined criterion to provide at least one group of a plurality of selected nodes in communications with a network infrastructure and that reestablishes the at least one group of plurality of selected nodes using a second packet data connection point.

16. The apparatus according to claim 15, wherein the predefined criterion comprises one or more selected from a group of membership to an Internet Protocol subnet in a source network, connection to an Internet Protocol Gateway, membership in a multicast group, usage of a beam-forming antenna resource, usage of frequency resources of time-multiplex, usage of time and frequency resources, radio capable, geographical location, geographical proximity, at least one multimedia capability of a node, at least one radio connectivity capability of a node, service subscription, at least one quality of service preferences, at least one security level requirement, at least one battery resource, at least one energy resource, at least one software upgrade, at least one software reconfiguration, and at least one management instruction of a node.

17. The apparatus according to claim 15, wherein the network infrastructure comprises one or more selected from a group of a wireless network, a radio network, a cellular network, a local area network, a distributed network, a mesh network, a push-to-talk network, a dispatch network, a telephony network, a broadcast network, an information technology network, a highway information network, a satellite network, a power grid network, and a security network.

18. The apparatus according to claim 15, wherein the controller circuit is triggered by any one or more selected from a group of an overload of a current packet data connection, transmission flow of a higher priority packet, data content request in substantially same format as at least one node on the network infrastructure, a change in power level, a need for a node reconfiguration based, at least in part, on a diagnostic test, a need for a service reconfiguration based, at least in part, on a diagnostic test, and at least one driver update.
