1. Field of the Invention
This invention relates generally to a wireless communication system, and in particular to a wireless broadcast communication system.
2. Background
Wireless communication networks typically have a plurality of servicing base stations which receive and transmit signals to users' devices within the service area of the respective base stations. Communication between a user and their respective base station is maintained as a user moves about the network service area by handing off the user from one base station to another.
Many new services are being offered to customers of wireless communication carriers. One such service is providing customers with multimedia content via the wireless communication network. For example, it is desired to provide audio/video content to customers as they move about the network.
Providing multimedia content via wireless communication networks presents several challenges. For example, maintaining bi-directional communication with a large group of customers that want to receive the content can utilize large amounts of network resources. In addition, keeping track of the customers as they move about the network and enter and leave the service areas of different base stations, and are “handed-off” to different base stations within the wireless network can consume large amounts of network resources.
Therefore, there is a need for improved systems, apparatus, and techniques for providing content, such as multimedia content, to customers via a wireless communication network.
