摘要:
A receiver in a wireless communication system detects a possibly interfering radar signal, and uses dynamic frequency selection to switch to a non-interfering channel. The power level and the channel of the radar signal may be detected. When a radar signal that exceeds a predetermined power level is detected, the receiver may be tuned until the channel of the radar signal matches the communication receiver channel. The communication receiver may then be tuned to a higher quality channel to mitigate or avoid interference between communication signals and the radar signal.

A method and apparatus for providing: multimedia services to a local area network includes processing that begins by receiving a plurality of channels from at least one multimedia source. The processing continues by receiving selection requests from at least one client module via a communication path. The processing continues by generating a set of channel select commands from the select request. The processing continues by selecting a set of channels from the plurality of channels based on the set of channel select commands. The processing continues by mixing the set of channels into a stream of channel data. The processing then continues by transmitting the stream of channel data via the communication path to the at least one client module such that each client associated with a client module receives the channel data for the respective channels that they had selected.

Embodiments of the present invention disclose a service processing method, a communication device, and a communication system. The service processing method includes: receiving a request message initiated by a user equipment (UE); and changing a current default bearer of the UE according to the received request message, to a bearer corresponding to a service that the UE needs to obtain in a current serving cell. The communication device includes: a generating unit, configured to generate a request message, where the request message carries information indicating a service required by the UE; and a sending unit, configured to send the request message generated by the generating unit to a network side, where the network side changes a current default bearer of the UE according to the information carried in the request message, to a bearer corresponding to a service that the UE needs to obtain in a current serving cell. According to the technical solution disclosed in the embodiments of the present invention, the UE can obtain the required service when moving between different serving cells.

A method and apparatus performing carrier management in a broadband wireless communication system supporting multi-carrier (MC) are disclosed. A method for a single- carrier supported mobile station (MS) to perform a carrier change with a MC supported base station (BS) includes transmitting a message indicating a support of a basic MC mode in which the MS is aware of a MC operation of the BS, receiving a carrier management command message including an action code and an action time on a serving carrier, transmitting, in response to the carrier management command message, a confirmation message indicating readiness of signal transmission/reception through a target carrier on a target carrier, and receiving a control signal and data from the BS on the target carrier, wherein the serving carrier and the target carrier are controlled by a common Medium Access Control (MAC) of the BS.

Devices and methods are provided for facilitating handing over to a hybrid femto access point that implements multiple radio access technologies (RATs), including a first RAT and a second RAT. In one embodiment, the method involves detecting a pilot from the hybrid femto access point, wherein the pilot is associated with the first RAT. The method involves registering with the hybrid femto access point on a first channel associated with the first RAT based upon the detected pilot. A system selection database is analyzed to identify a second channel associated with the second RAT, and a selection to handover to the identified second channel is effectuated.
