1. A method comprising:
- sharing a signaling interface between a first entity with a first power control profile and a second entity with a second, independent power control profile;
establishing a first security association between the first entity and an endpoint;
establishing a second security association between the second entity and the endpoint; and
transmitting a keepalive message over a communication channel associated with the second security association.

Abstract
Cooperating entities share a signaling interface. Each entity establishes a security association between itself and an endpoint, and one of the entities transmits keepalive messages over a channel associated with the security association. Chipsets and systems to implement related methods are also described and claimed.

19. A machine-readable medium containing instructions to cause a programmable logic device to perform operations comprising:
-
establishing a security association between a system and a communication endpoint, the security association to be shared between a first entity and a second entity;
placing the first entity in a suspended state; and
transmitting a keepalive message from the second entity to the communication entity while the first entity is suspended. - View Dependent Claims (20, 21)
