Abstract

Embodiments of User Equipment (UE) and methods to support reception of content for use by an application supported by a Port Control Protocol (PCP) client are disclosed herein. The UE may receive, from a PCP server, a first portion of video content for use by the application during a first time period. The UE may send a PCP update message that includes one or more mobility status parameters. The UE may receive a second portion of the video content for use by the application during a second time period. The first and second portions of the video content may be received from a first and a second mobility anchor, which may operate as relays for the PCP server. The second mobility anchor may be determined based on a referred IP prefix included in the PCP date update message.
