A system and method for enabling scheduled data messages to be transmitted within a communication system on a controlled access packet data channel. When a scheduled data message is to be transmitted, a mobile device generates the data message, appends a predetermined type of header to the data message, and passes the data message to a communication unit. The header comprises an hour field, a minute field, and a slot field indicative of a specific time when the data message is to be transmitted on the controlled access packet data channel. After receiving a data message from the mobile device, the communication unit parses the received data message to determine whether the received data message should be processed as a scheduled data message on the controlled access packet data channel, and transmits the data message to a fixed network at a specific time based on the hour, minute, and slot fields in the header.

When polled, a remote unit () provides a radio access network (RAN) with an acknowledgment message. The acknowledgment message contains information such as the current window size, the number and identification of frames received in error, . . . etc. The polling frequency is based on a channel condition metric. More particularly, active polling timers that control the transmission of status information over the air interface are adjusted based on a bit error rate (BER) of radio channel such that as the BER of the radio channel decreases less control information is transmitted. Similarly as BER increases the timer values will change such that more control information is transmitted.

Interference reduction within a communication system

An apparatus and method that schedules and allocates data transmissions over communication channels within a broad-band communications system is provided. Data transmissions are first scheduled with priority to data service users granted access to radio resources first, until more data transmissions require service than there are radio resources available. Then, data transmissions are scheduled according to a resource scheduling priorityas determined by a resource scheduling function within a resource scheduling and allocation algorithm. The resource scheduling function considers various communications parameters (e.g., frame count, transmission time, number of data frames queued, signal/noise ratio, frame error rate (FER), bit error rate (BER), transmission delay, jitter, etc.) and can be implemented to treat data service requests proportionately (algorithm) or disproportionately (algorithm). Once assigned, allocation of the radio resource to a given data transmission is based on a resource allocation parameter(e.g., frame count, transmission time).

A communication connector having a plurality of contact pairs for conductive connection to respective communication signal wire pairs is provided with a capacitor label that capacitively couples a first contact of one contact pair to a second contact of a second contact pair to reduce near end cross talk between adjacent contacts. A common conductive lamina disposed closely adjacent to and spaced from more than one of the contacts further improves near end cross talk performance of the communication connector.

A method and apparatus for adjusting a communication timer ( ) for a communication network is described herein and comprises a communication device ( ) capable of receiving data indicating that a data transfer rate has varied from a previous data transfer rate to a new data transfer rate, determining the amount the data transfer rate has varied, and adjusting the communication timer ( ) from one set timed interval to a different set timed interval to automatically account for the varying data transfer rate and for optimizing data transfer between networked components.

In order to reduce messaging within a wireless communication system an emulator (137) is provided that receives multicast packet data from a router (138). The multicast packet data is transmitted from a server (120) and destined to at least one remote unit (113-117). The emulator (137) additionally receives control data for the current multicast session from the router (138). The first set of data is transmitted to the remote unit (113-117) and the emulator (137) responds to the control data (via a response message (134)) without transmitting the control messages to the remote unit (113-117).

Data transmission within a wireless communication system

Remote units (113-117) that wish to receive a multicast session, monitor a multicast advertisement message on a system broadcast channel to determine a session to receive. Once a remote unit (113-117) requests participation in the multicast event, a common supplemental channel (205) is assigned to the remote unit (113-117), and the multicast session is broadcast to all remote units (113-117) currently participating in the multicast event. The common supplemental channel (205) utilizes two unique spreading codes for channel assignment, with one of the spreading codes being a function of the multicast session address (501) that is broadcast by the server (120).

Channel assignment within a broad-band communication system

During data transmission to a remote unit (113) utilizing a supplemental, high-speed data channel (105), data transmission stops due to all data being communicated to the remote unit (113) or because of an interruption in transmission. In the situation where all data has been transmitted to the remote unit (113) the remote unit (113) will drop the supplemental channel (105) prior to acknowledging reception of the last frames transmitted, and acknowledgment will take place utilizing the low-speed fundamental channel (103). In the situation where an interruption occurs, data transmission will continue utilizing a fundamental channel (103) if less than a predetermined amount of data remains to be transmitted.

Method and apparatus for data transmission within a broad-band

Data transmission within a broad-band communication system occurs as follows: During time periods where a remote unit (113) is not actively communicating to a base station (100) utilizing either a fundamental or a supplemental channel, the remote unit (113) is actively or periodically monitoring a forward control channel (IS-95A paging channel) for notification of any pending transmission by the base station (100). The base station (100) determines that a high data rate transmission to the remote unit (113) needs to take place and determines if supplemental channel circuitry (105) is available for utilization. Shortly prior to supplemental channel availability, the base station (100) notifies the remote unit (113) of a pending data transmission and assigns the remote unit (113) a fundamental channel to establish an appropriate transmit power level. Finally, data transmission to the remote unit (113) takes place utilizing the supplemental channel.
