Claim Text:
1. A method of a wireless transmit/receive unit (WTRU) maintaining communications connectivity for a plurality of applications and reducing unnecessary message transmissions, the method comprising: providing a client proxy to interface with a plurality of client applications and a first protocol stack, wherein the WTRU contains the plurality of client applications, the client proxy, and the first protocol stack, and wherein each of the client applications sends keep-alive messages at a respective signaling rate; each of the client applications registering with the client proxy and indicating a respective keep-alive message signaling rate; the client proxy determining an optimal signaling rate based on the respective keep-alive message signaling rates indicated by the client applications; the client proxy generating an application layer proxy keep-alive message associated with the client application keep-alive messages; the client proxy forwarding the application layer proxy keep-alive message to the first protocol stack; the first protocol stack transmitting the application layer proxy keep-alive message at the optimal signaling rate; providing a network proxy in a network node to interface with a second protocol stack and the client proxy; the second protocol stack receiving the application layer proxy keep-alive message and forwarding the application layer proxy keep-alive message to the network proxy; and the network proxy managing the re-creation and distribution of the client application keep-alive messages based on information included in the application layer proxy keep-alive message and registration information.
