A method, an apparatus, and a computer program product for wireless communication are provided. In one configuration, the apparatus is a target UE. The target UE communicates an expression of the target UE to a serving entity, receives a page initiated from the serving entity for communicating with an initiator UE, and communicates securely with the initiator UE based at least on the page. In one configuration, the apparatus is a serving entity. The serving entity receives a first expression from a target UE, receives a second expression from an initiator UE, and sends a page to the target UE upon determining that the second expression matches the first expression.
