  • Patent number: 8730998
    Abstract: Disclosed is a method and apparatus for transmitting/receiving control information in a system in which one or more Radio Frequencies (RFs) are used to carry multiple services through a frame constituted by time resources or time-frequency resources. Control information regarding frame configuration information is not transmitted over a separate control channel but over a data channel through which to transmit primary service traffic among all service traffic, and each non-primary service traffic other than the primary service traffic includes control information for a primary service. Thus, even when a receiver changes the current service to a target service, control information necessary to detect the location of the target service in a frame and demodulate the target service can be acquired, and thus a service change can be made without reading a separate control channel.

  • Patent number: 8619817
    Abstract: A communication gateway receives an Internet Protocol (IP) message sourced from a first IP address and directed to a second IP address. The gateway associates the first IP address with a code. The gateway processes the second IP address to identify a Radio Access Network (RAN) address. The gateway transfers the IP message directed to the RAN address and sourced from the second IP address. The IP message uses the code as the source port number. A base station receives the IP message, and in response to the RAN address, wirelessly transfers the IP message to a routing system. The routing system wirelessly receives the IP message and forwards the IP message based on the second IP address which is now in the source address field.
