摘要:
A method and apparatus for an overhead processing system is described. More particularly, frame latency is used to process less time-critical overhead with the overhead processing system. Such a system uses less semiconductor wafer area and consumes less power than processing all overhead in a time-critical manner using flip-flops and the like.

A method of transmitting feedback information in a wireless communication system is disclosed. More specifically, the method comprises a mobile station (MS) which determines whether to transmit feedback information to a base station (BS) without solicitation from the BS. After determining to do so, the MS transmits a request message to request the BS to allocate an uplink resource for transmitting at least one unsolicited header and thereafter receives the uplink resource allocation from the BS. Lastly, the MS transmits the at least one unsolicited header via the allocated uplink resource.

A method of detecting control tones in a digital signal by using a tone detection unit (11) (TDU) and a packet voice protocol unit (12) (PVPU) in a network over which the signal is transmitted. The TDU (11) detects the presence of a control tone in the signal within the first 5 ms of transmission and generates an alert signal (23) to the PVPU (12) to cease further transmission of the signal. Upon confirmation, the PVPU (12) may halt the transmission and buffer or delete the voice signal packets. Alternatively, if the control tones are not present in the signal, the PVPU (12) may continue transmission of any buffered packets. The method further incorporates the sending of the control tone signal to the receiving end of the transmission of the voice packets following transmission of the control tone to the receiving end.

Billing in a packet switched communication system is based on the quality of service (QoS) associated with each session a user may be involved in or establish, separate from the physical circuits they consume. In the preferred embodiment, a session may be, but is not limited to, a voice connection, an internet connection or a video conference connection. This QoS measure may be combined with total packets exchanged during a session to arrive at a connection detail record. If such a packet switched communication system is coupled to an access network (145), such as a wireless communication system, the use of a single radio channel in the wireless communication system may result in the generation of several detail records based on the number of distinct sessions in which a user engages.

In a communication between a mobile unit (UE) and a gateway general packet radio system (GGRS) support node (GGSN) wherein resource reservations setup protocol (RSVP) capabilities are shared there between by a session setup mechanism, preferably session initiation protocol (SIP) in which RSVP capabilities of the UE and GGSN are defined and exchanged. In addition, the SIP is utilized to identify the preferred RSVP mode of operation by negotiations. The SIP is utilized to indicate that : the UE is RSVP capable ; those media flows which are based on RSVP ; the preferred mode of operation i.e. either UE based RSVP signaling or GGSN proxy based RSVP signaling and to communication a final setup mode for RSVP signaling to the UE from policy control function (PCF). The SIP may also be employed to enable the UE and network to indicate intended quality of service (QoS) protocol during a call setup procedure. The SIP is further utilized to enable the terminating UE and/or network to indicate in their response the capability of supporting a particular QoS protocol, the call being rejected with a clear indication of the cause when the terminating network is not capable of supporting the proposed QoS protocol.

The present method (200, 300, 400) and device (500, 600, 700) modify phase two of the format set forth in the V.34 Recommendation of the International Telecommunication Union-Telecommunication Standardization Sector to prevent premature disconnection of calls between a call modem and an answer modem. The method and device efficiently ensure connection of the call for high speed data transmission over voiceband channels, by modification of one of: a phase preliminary to phase one and phase two. One implementation, in the answer modem, includes transmitting a signal having first information, followed by a Signal S comprising a guard tone and a signal SI, wherein an energy of a predetermined guard tone is greater than an energy of a predetermined range of frequencies of the Signal SI; and continuing transmitting and receiving in accordance with the modified V.34 operation.
摘要:
Methods and systems for routing messages between a mated pair of routing nodes with a distributed processing architecture and one or more redundantly connected remote applications are disclosed. A mated pair of routing nodes uses private point codes to distribute messages destined for remote applications among internal processing modules and between the routing nodes. The routing nodes replace the private point codes with a shared point code before sending the messages to one of the remote applications. When communicating with external PSTN nodes, the mated pair of routing nodes uses the shared point code.

This invention provides a method of operating a mobile station (MS), and a MS (10), that includes in one aspect adapting a protocol revision level in a MS Classmark information element (IE) to follow a protocol revision of a wireless network, and that includes in another aspect adapting a Quality of Service (QoS) information element sent by the MS to a Service General Packet Radio Service (GPRS) Support Node (SGSN) release version in the wireless network. In a further embodiment this invention provides a method of operating a MS that includes adapting operation of the MS to Enhanced General Packet Radio Service (EGPRS) capabilities of a serving cell of a wireless network.
