To enable both point-to-multipoint and point-to-point communication services in an existing cellular communication system infrastructure, a apparatus and system for channel management and overhead functions associated with use of the assigned channels for point-to-multipoint services in the cellular communication system infrastructure are described. These devices and methods prevent undesirable interruptions of total internal reflection of a prism that result in biometric images having a halo effect. The amount of resource allocation requested may be coordinated by exchanging messages with a call controller or policy server for one of the endpoints of the media flow, or the amount of resource allocation may be identified within the received message. This invention particularly relates to use of transparent, luminescent polymer compositions comprising ethylene acrylic acid copolymers and rare earth ions and transparent, luminescent polymer compositions comprising methyl acrylateacrylic acid copolymers, fatty acids and rare earth ions for these purposes.
