A system for wireless data transmission that uses a channel bandwidth, channel separation, and radio frequency power spectrum which is compatible with existing deployments of wireless voice services. The transmitted waveforms are thus compatible with existing cellular networks. However, the time domain digital coding, modulation, and power control schemes are optimized for data transmission. Existing cellular network sites can thus be used to provide a high speed service optimized for wireless data traffic without the need for new radio frequency planning, and without interfering with existing voice service deployments.

Method and apparatus for a spectrally compliant cellular communication system

The described embodiments concern verifying operation of a device, where the device may have one or more inputs and/or one or more outputs. At least one input and/or output is associated with an intelligent connector. An intelligent connector is a combination of a signal transport path and a data structure. The signal transport path may be electrical conductors leading to the device or a physical connector associated with the device. The data structure contains the name of a variable transported by the associated physical connector, an address of the variable itself as a value in memory, and further information of a source device that produces the variable, at least in the form of address or pointer to the source device data structure and the addresses of all destination devices that consume the variable.

Model based verification using intelligent connectors

A technique for integrating services digital network (ISDN) and code division multiple access (CDMA) or other digital wireless communication protocols by a technique that strips off lower protocol layers, such as layers one and two of the ISDN protocol and sending only layer three and above messages over a more efficient wireless protocol.

Protocol conversion and bandwidth reduction technique providing multiple NB+D ISDN basic rate interface links over a wireless code division multiple access communication system

A code division multiple access (CDMA) user device configured to dynamically allocating at least one wireless communication channel to permit a more efficient allocation of wireless communication channels when providing high speed data service. The CDMA user device is configured to receive data traffic from at least one data buffer in a base station. The CDMA user device is dynamically allocated at least one wireless communication channel based on an urgency factor. The urgency factor indicates the urgency of traffic data to be transmitted from the at least one data buffer in the base station to the CDMA user device.

Dynamic bandwidth allocation for multiple access communications using buffer urgency factor

A technique for transmission of wireless signals across CDMA radio links. Bandwidth is allocated dynamically within a session to specific CDMA subscriber unit based upon data rate determinations. Specifically, a dynamic bandwidth allocation algorithm operates from limits calculated based upon available ports per subscriber, expected user bandwidth, and parallel user bandwidth versus throughput. Provisions for priority service, unbalanced forward and reverse spectrum utilization, voice prioritization, and band switching are also made.

Dynamic bandwidth allocation to transmit a wireless protocol across a code division multiple access (CDMA) radio link

A code division multiple access (CDMA) user device configured to dynamically allocating at least at least one wireless communication channel to permit a more efficient allocation of wireless communication channels when providing high speed data service. The CDMA user device is configured to receive data traffic from at least one data buffer in a base station. The CDMA user device is dynamically allocated at least one wireless communication channel based on an urgency factor. The urgency factor indicates the urgency of traffic data to be transmitted from the at least one data buffer in the base station to the CDMA user device.

A scheme for assigning priority levels to users based upon a history of their request for access to the resources. If a user has, over a historical period of time, made fewer demands than a stated amount, that user is given a higher priority than a user who has made greater use of the resources than their stated amount. Thus, users making the heaviest demand on the available resources are allocated fewer resources despite their demand, whereas users that make less demands for the resources are granted more of the resources they request. An additional feature of an access allocation scheme according to the present invention is to reserve at least some resources for the users at the lowest priority levels. Thus, even users being assigned to a lowest priority queue will be granted at least some access once in a while. A third feature in connection with the present invention is to use the time of continuous transfer as a threshold to drop a presently assigned priority. For example, when a user at a particular priority level has made continuous use of resources for a predetermined time, that user is reassigned to the next lowest priority level and its resources are taken away. The user is then required to vie again for access to resources at this lower priority level.

A subscriber access unit for transferring session context in wireless communication is disclosed. The access unit contains first context establishing circuitry for establishing a first wireless session context associated with a first wireless coverage area; locating circuitry for determining whether the subscriber access unit is located concurrently in the first wireless coverage area and a second wireless coverage area; loading factor receiving circuitry for receiving a first loading factor and a second loading factor indicative of a throughput load associated with the first and second coverage areas respectively; comparison circuitry for comparing the first loading factor with the second loading factor; and second context establishing circuitry for selectively establishing a second wireless session context continuous with the first wireless session context, the second context associated with the second wireless coverage area, based on output of the circuitry comparing the first and second loading factors.

Optimal load-based wireless session context transfer

A base station includes a wireless transceiver for establishing a communication session over a first digital communication path, and a bandwidth management module is connected to the wireless transceiver for allocating at least one code channel within the at least one radio frequency channel for exchanging digital signals over the first digital communication path during the communication session. The at least one code channel may include at least one traffic portion that is established for a predetermined time and at least one control portion that is continuously available. The bandwidth management module may reallocate the at least one traffic portion from the first digital communication path to a second digital communication path if an extension of time is not requested from the base station over the first digital communication path for the at least one traffic portion, or if the base station no longer has digital signals to transmit over the first digital communication path via the at least one traffic portion. However, the at least one reallocated traffic portion appears as though it is still continuously available to the first digital communication path.
