    摘要: A wireless communication system facilitates communication with subscribing units within a respective service area that supports at least one communication protocol revision. The system communicates with a subscribing unit operating within a respective service area to determine the communication protocol revisions supported by the subscribing unit. Subsequently, the subscribing unit and base station communicate according to a supported communication protocol revision. The base station and subscribing unit further communicate to indicate extended services supported by the subscribing unit and the methods of delivering the extended services to the subscribing unit. The extended services include caller line ID, message waiting indications and short message services among other extended services. In addition to a base station, the wireless communication system may include a mobile switching center that is in communication with the base station. The mobile switching center includes a visitor location register that records communication protocol revisions of the subscribing unit.

    摘要: Source routed multicast LSP is described herein. In one embodiment, when a first node receives a first packet having a label stack including a plurality of labels compatible with MPLS (multi-protocol label switching), in response to a first label on a top of the label stack, the first packet is duplicated into a second packet. In addition, at least two labels are popped from the top of the label stack of the second packet forming a third packet. Thereafter, the first and third packets are processed based on a label on the top of the label stack of the first and third packets respectively. Other methods and apparatuses are also described.

    摘要: Methods and apparatus for performing finger de-spreading and MRC combining are provided. A large antenna buffer is used to buffer all the finger signals of the same user so that the receiver can do both de-spreading and MRC at the same time without buffering the de-spreading finger symbols. For each user, a reference time is introduced to align all the finger signals of the same user in the Antenna Buffer. The reference time delay is used to generate the PN codes for de-spreading, as well as to count the number of symbols in a PCG or a frame. Methods for antenna buffer arrangement, interpolating filter implementation, channel estimation and MRC for traffic data channels, timing for the user's finger signal de-spreading and MRC, long code and short code generation for de-spreading, new finger allocation and finger timing adjustment.

    摘要: A method of reducing Raman tilt in a transmission apparatus capable of transmitting a plurality of signals, occupying contiguous channels in a transmission band, through a length of optical transmission cable which exhibits the Raman effect of transferring energy from the shorter wavelength signals at one end of the transmission band towards the longer wavelength signals at the other end of the transmission band, including the transmission of half the maximum number of signals at twice the normal channel frequency spacing at a higher-than-normal level and the transmission signals in selected ones, fewer than all, of the available channels at the normal channel spacing at a normal power level. As new channels are added at the lower frequency channel spacing, the powers of both neighboring channels are reduced to the normal power level.

    摘要: A conversion entity and method for converting higher-rate speech parameters into lower-rate parameters including dimmed excitation parameters. The conversion entity comprises a first decoder configured to produce a target excitation from the higher-rate parameters, based on a first fixed contribution and a first adaptive contribution. The conversion entity also comprises a second decoder configured to produce a second adaptive contribution, and configured to selectably operate in a first or a second mode. In the first mode, the second adaptive component is generated based on the first fixed contribution for a previous frame, while in the second mode, the second adaptive component is generated based on a second fixed contribution for the previous frame. The second decoder operates in the second mode in response to a rate reduction request. A processing module determines the dimmed excitation parameters for generation of the second fixed contribution for the current frame, based on the target excitation and the second adaptive contribution.
