摘要:
A communications system improves performance of detecting a signal having an indication of a request to change communications states by making at least two positive identifications of the request in a given time frame. The system may further improve performance by applying a difference in power levels for a non-request state (i.e., steady state or ‘control hold’ state) versus a request state (i.e., ‘request to change’ state). In one particular application, a base station determines a request to change communications states with a reasonably high probability of detection and a reasonably low probability of false detection. The system has a reduced number of erroneous communications states, such as erroneous traffic channel allocations. The detection technique is compatible with 1xEV-DV systems and I-CDMA systems, but general enough to support systems employing various other communications protocols used in wired and wireless communications systems.

A communications network is disclosed and includes a broadband communication line having a first derived voice channel and a second derived voice channel, wherein the first and second derived voice channels are established as a function of an available bandwidth associated with the broadband communication line. The communication network further includes a residential gateway in communication with the broadband communication line. The residential gateway includes a switch, a network interface device in communication with the switch, and wherein the switch is configured to select at least one of the first or second derived voice channels for voice communication over the broadband communication line as a function of the available bandwidth.

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 communication system, such as a wireless CDMA system, detects markers with fewer errors by having field units transmit the markers at different power levels (e.g., 9 dB for one marker and 11 dB for another marker). The difference in power levels of the markers allows the base station to identify the request markers using alternative criteria with a low probability of error, where the alternative criteria may include comparing the markers to respective energy level thresholds, monitoring occupancy of time slots, occupancy of mutually exclusive code channels, or combinations thereof. For example, in one particular embodiment, a request marker, which is generally a high priority marker, is transmitted with higher power, which improves the probability of detection and reduces the probability of false detection of the request marker.

To allow a call received from an accommodated device to arrive at the other party by diverting the call from an IP network to a detour network even with different numbering systems between communications over the IP network and over the detour network. A VoIP gateway apparatus 1 includes an ISDN terminal side IF portion 101, an IP network side IF portion 102, an ISDN network side IF portion 103, a condition storage portion 109, a detour determining portion 108, and a number editing portion 106. The detour determining portion 108 determines whether a call arriving at the ISDN terminal side IF portion 101 satisfies a detour condition stored in the condition storage portion 109 or not. If so, the number editing portion 106 edits the called party number of the call under a number editing condition stored in the condition storage portion 109 and then transmits it from the ISDN network side IF portion 103. If not, the call is transmitted from the IP network side IF portion 102 without editing the called party number.
摘要:
A service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a given long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none, one, or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physical connections between the subscriber units and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber units are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronism in an idle mode and also request additional channels. This in turn allows fast acquisition of additional subchannels as needed by allocating new code phase subchannels. Preferably, the code phases of the new channels are assigned according to a predetermined code phase relationship with respect to the code phase of the corresponding maintenance subchannel.
摘要:
A system and method for delivering a communication signal to a subscriber without incurring right-of-way franchise fees associated with the signal. A central office on a first side of a right-of-way is in communication with a multiplexer on a second side of the right-of-way opposite the first side. The central office transmits a signal (e.g., a telephony signal) to the multiplexer such that the signal crosses the right-of-way. A wireless receiver on the second side receives another signal (e.g., a video signal) and transmits the other signal to the multiplexer. The multiplexer combines the signal and the other signal into a combined signal for routing to the subscriber (located on the second side). Because the communication of the other signal occurs entirely on the second side and does not access or cross into the right-of-way, the addition of the other signal avoids the imposition of a right-of-way franchise fee.

A method of signal communication includes receiving a selection signal, and selecting a selected frequency range used for a multi-carrier signal communication from a set of predetermined frequency ranges for signal communication depending on the selection signal. The set of predetermined frequency ranges includes a first frequency range and a second frequency range including the first frequency range.

An apparatus and appertaining method are provided in which a transmission entity eliminates a frame word of a payload data service and transmits in payload data service in a common frame with payload of other services. Additionally, a transmission unit can provide first payload data and second payload data in a payload section of a common frame, where an entity provides an overhead section in the common frame, the overhead section comprising a common eoc channel which comprises control information related to a transmission path and to one or more transmitted services or terminal equipment types. A transmission entity can transmit overhead data in an overhead section and transmit payload data of a service in a payload section, wherein the transmission entity is configured to relocate information content of operational bits of the service transmitted in the payload section to an eoc channel provided in the overhead section.
