Abstract: A method and apparatus for transmitting signaling messages over the communication channel to a CDMA mobile station. If a one-half, one-quarter, or one-eighth frame voice packet is to be transmitted, augmenting that packet with signaling information to form, essentially, a full rate frame; if no more than N consecutive full rate frames are detected, deferring transmission of the signaling message, and thereafter, if another full frame voice frame is detected, substituting a frame of signaling information for the full frame voice frame. Advantageously, using this arrangement, most short signaling messages can be transmitted to a CDMA mobile station with minimal voice impairment.

Abstract: An apparatus, method and system are provided for a hand-off of a communication session in a wireless data network system, in which the communication session has been established previously with a mobile unit through a first base station, a first serving routing node and a gateway routing node utilizing a first addressing context. The preferred method embodiment includes, when a second base station has been selected for hand-off, first establishing a second addressing context, for the mobile unit, between the gateway routing node and a second serving routing node. The gateway routing node then concurrently routes incoming data packets for the mobile unit to the first serving routing node utilizing the first addressing context and to the second serving routing node utilizing the second addressing context.

Abstract: Methods and apparatus for transmitting packets from a source of such packets to one or more radio station sites so that the radio station sites can transmit the packets at the correct real time. Each radio site has an independent source of exact time based on the reception of signals derived from satellite inputs. Using the real time calculated by a base station, the base station calculates an offset between the time of arrival of a signal with a specified time marker, and the time that a signal with that specified time marker should have arrived in order to be transmitted in a timely fashion. The offset is sent back to the source of packets, and used by the source of packets to advance, or retard, the transmission of future packets. Advantageously, packets can be transmitted from each base station at the correct time, and if packets are being transmitted for a given call from several base stations, can be transmitted simultaneously, by these base stations.

Abstract: A system for expanding a parameter encoding field in a new communications protocol that is compatible with an old protocol. An unused command parameter in an old protocol is used to indicate an expanded parameter encoding field in a new protocol. Parameter encodings from the old protocol are unchanged in the new protocol. A system communicating using the old protocol recognizes all parameters from the old protocol and ignores parameters from the new protocol. A system communicating using the new protocol recognizes parameters from both the old and new protocols.

Abstract: The sharing of trunk groups is accomplished by performing incoming call routing analysis on the incoming call to determine if the call is intended for wireless applications on the network or for wireline applications on the network. The results of the incoming call routing analysis form the basis for determining those actions necessary to process the call. If the incoming call is wireless, executing the wireless related application code, notify the mobile switching center of the incoming call, and wait for directions. If the incoming call in wireline, attempting to deliver the call to a particular wireline, fire an advanced intelligent network (AIN) terminating trigger, and tandem the call through to another switch. Outgoing calls are simply allowed to hunt across shared trunk groups rather than being limited to trunk groups specified for the application.

Abstract: An improved ergonomic computer mouse provides comfortable and efficient usage by maintaining the hand of a user at a large acute angle to the horizontal. This is accomplished by a device that includes a base having an upstanding pedestal structure about which the palm and hands of the user extends in a more natural handshake manner at a large acute angle to the horizontal whereby the users wrist remains straight while grasping the mouse. Control means in the base and upstanding structure within easy reach of the users fingers allow the user to efficiently and comfortably control the computer operations. Indentations and an enlarged upper head portion provide for comfortable grasping and easy lifting of the mouse. The pedestal may be rotated 180 degrees to accommodate both right and left handed use. Add-on OEM, and custom fitted embodiments are also disclosed.
