  • Patent number: 8169926
    Abstract: Enhanced channel changing within multi-channel communication systems. A CMTS directs channel changing of a CM, sometimes between upstream data bursts. Logical channels, part of a single frequency channel, may be used, and the channel changing may be performed between those logical channels. Multiple upstream burst profiles and/or modulation densities may be used providing high degrees of robustness, fidelity, and throughput and allowing great channel flexibility. A CM may be switched between channels without losing transmitter capability. Even if some throughput rate may be sacrificed during the channel changing, the CM will still be able to continue data throughput. Then, the new channel may then undergo the initialization and ranging processes thereby enabling greater throughput on that new channel. After undergoing the initialization and ranging processes, the new channel will then be a fully equivalent member of the CM communication system.

  • Patent number: 8169962
    Abstract: A radio access network (RAN) receives a request to route a call from a caller to a mobile station, assigns a wireless traffic channel to the mobile station for the call, and detects a no-answer condition for the call (because a user of the mobile station does not answer the call within a predetermined time period or has chosen to ignore the call). In response to the no-answer condition, the RAN redirects the call to a voice mail system and keeps the wireless traffic channel assigned to the mobile station while the caller interacts with the voice mail system. The RAN determines that the caller has left a voice mail message on the voice mail system and transmits an indication of the voice mail message to the mobile station over the wireless traffic channel.
