Methods and apparatus for optimizing the exchange of capabilities or other request messages across a network. In an exemplary embodiment, IMS architecture is disclosed which leverages the Session Initiation Protocol (SIP) to optimize the exchange of capabilities of various user equipment (UE) client devices present on a network. The IMS architecture leverages intermediate entities (such as a home network gateway) to collect the capabilities of all UE devices on a given home network and forward this collected capability information onto a requesting UE device. The requesting entity generates a capabilities request message and appends this message with an information element that requests the capabilities of all UE devices on a given network (such as a user's home network). In response, the receiving device or intermediate entity generates a capabilities response message that includes the capabilities of all UE devices on the requested network. In this manner, signaling messages are reduced. |
