A method and system for providing telephony services over a data network is disclosed. According to one embodiment, a service provider enters a service plan with a user. The service plan ensures the user a fixed cost for a substantial long period regardless how long the telephony service is used by the user. Further the service plan requires no purchase of any equipment nor regulates the use of the services in terms of time or distance. The service plan is incorporated in a gatekeeper that is co...

A physical channel of a user service is provided for assignment to a set of time slots in a hybrid time division multiple access/code division multiple access wireless communication system. A measure of interference is determined for each of the set of time slots. A fragmentation parameter is provided. The fragmentation parameter represents a preference for fragmenting user service physical channels over time slots. The user service physical channel is assigned to one of the set of time slots us...

A communication node for enabling interworking of a first network in which data transfer is based on a combination of request and response and a second network in which data transfer is not based on a combination of request and response is disclosed. In the communication node, a packet conversion processing is applied to a first packet received by the first interface on the first network side so as to obtain a second packet corresponding to the second network at a time of executing an applicatio...

Apparatus, and an associated method, for allocating resources in a communication system, such as a multi-code, multi-rate CDMA communication system. Communication indicia by which data to be communicated during operation of the communication system is coded and modulated is selected responsive to communication characteristics of the communication channel upon which the data is to be communicated. The levels of coding and modulating are determined responsive to measured levels of the communicatio...

A linecard (175) permits an increased rate connection between a subscriber (15) and a service provider (40) over the PSTN (50) includes an analog interface (152) a digital interface (165) coupled to the digital backplane (170) to the service provider's host server (34), a conversion circuit (258) interspersed between the analog interface (152) and the digital interface (165), and a linecard microcontroller (300) configured to request bandwidth on the backplane (170) A linecard (175) incorporates...

A determination is made whether a service provider (28, 40) is capable of supporting at least one service for one of a plurality of subscriber units (30-36, 42-46). The determination is based on whether the service provider has sufficient processing capabilities and memory to receive the service processing software from the subscriber unit and/or whether the service provider is authorized, based on communication system policies to process the particular service request for this subscriber. If th...

A method and system for communication in a system area network (SAN) data processing system are described. The SAN includes a plurality of interconnected nodes that each have at least one port for communication. To avoid communication-induced errors that may arise, for example, if multiple nodes share the same node ID, the port of a node in the SAN is marked as "fenced" to prevent transmission of packets of a first traffic type while permitting transmission of packets of a second traffic type. T...

In a novel restoration management method and system, the restoration messages are treated in two ways simultaneously so as to avoid delay in transmitting to a next node. In particular, a router alert bit is attached to each restoration message at an edge of the restoration network, which is read by a Label Switched Router so as to identify the restoration message as such. Then the restoration message is duplicated. The original one is directly forwarded to the next node through the shim player s...

A wireless network can be easily optimized utilizing processes according to the present invention. A simulation environment allows a network engineer to vary parameters (e.g., antenna height, tilt, and power) of a virtual model of the wireless network and observe how the changes affect coverage. Algorithms also enable hand off timing parameters for sectors in a wireless network to be optimized. One algorithm analyzes measured data regarding network coverage and regional terrain to arrive at a re...

A method and apparatus is provided for efficient processing of signal in a communication system. The processing of the signal for transmission may include encoding a block of data at an encoding rate 1/R. The encoding produces R number of data symbols for every data bit in the block of data. A block of RAM (299, 600) is partitioned into a plurality of blocks of RAM to allow reading simultaneously data symbols from the plurality of blocks of RAM to produce an in-phase and a quad-phase data symbol...
