    摘要: The present embodiments provide apparatuses, methods and systems for use in notifying a remote communication device when a local wireless device loses its wireless link. In some embodiments, a method detects when a wireless connection is lost with a first communication device, identifies a second communication device that is communicating with the first device, and notifies the second device of the lost link. In some implementations, the notification of the lost link is supplied while the method provides batch communications. Some embodiments provide voice communications, where a remote device is notified when a local device loses its wireless connection. The second device can be determined by querying a server. The notifying can include forwarding an in-band tone, and/or generating a real time protocol packet. In some embodiments, the loss of the link is detected through a radio access network, a packet control function, and/or a mobile switching center.

    摘要: A server (101) designates and assigns each of a plurality of communication devices to at least one of a plurality of groups. The server (101) prepares a communication having presence information corresponding to a status of the communication devices in the group; determines network infrastructure device(s) serving the group; and transmits, at a pre-determined time, the communication to the network infrastructure device(s). A network infrastructure device (103a-c, 105a-f) receives the communication and transmits, as a common channel signal during the pre-determined time, a signal with the presence information. A communication unit (107a, 107b, 107c) receives an indication of the pre-determined time; transmits, at an interval proximate to the pre-determined time, a signal indicating the communication device's status; and receives, at the pre-determined time, the signal with the presence information.

    摘要: A system and method for reducing the transmission delay of messages sent through a network from a source mobile unit (112) to a destination mobile unit (114). Portions of a data message are received (202). The portions of the data message are decoded (204) and a type of the data message is determined from the decoded portions. Before the entire data message has been received, processing and service actions are performed as a result of receiving the data message (206) based at least in part upon the type of the data message.

    摘要: A call management system (136) and method that allows a first wireless voice call to be temporarily disconnected at a mobile device (130) while another communications session is performed from the same device (130). During a first voice call between a wireless communications device (130) and a second party, a network hold command is received. The second party is then placed on hold and wireless communications resources for the first wireless call are released. The wireless communications device (130) is subsequently reconnected to the second party. The reconnection includes removing the second party from hold and connecting the second party to the second voice call. A unit identifier (240) identifying the wireless communications device (130) is stored in an infrastructure database (114) along with an identifier of the first voice call to facilitate reconnection. Prior to reconnection, a wireless data communications session can be performed.

    摘要: Various embodiments are described herein to address the need for providing substantially reduced PTT call setup delays. Modifications to channel assignment request messaging (400), such as an IS-2000 Reconnect Message and an IS-2000 Origination Message, are described. In addition, the use of common control channel signaling (e.g., 201), changes to page response messaging (e.g., 301) and new uses for A9-Short Data Delivery messaging (e.g., 203 and 303) are described. Embodiments incorporating some or all of these protocol changes, can provide reduced end-to-end call setup time for PTT as it presently exists in IS-2000 systems.

    摘要: The present embodiments address the need for a reduced resource dormant state for packet data systems (100) that substantially provides the benefits of current dormant mode operation but without the resource maintenance costs. After a period of MS session inactivity, PCF resources, certain PDSN resources, and the PCF-PDSN tunnel are released in order to enter a new reduced resource dormant state. When data arrives for a reduced-resource-dormant MS (101), PDSN-initiated messaging (303) is used to trigger the re-establish PCF resources, a PDSN-PCF tunnel connection (320), and released PDSN resources.

    摘要: A cellular radiotelephone system transfers a call from a source base-site (200) to one target base-site (205,210). A source base-site (200) in the first RF coverage area (100) measures the signal strength (RSSI.sub.S) of a mobile (225), provides a forecasted signal strength (RSSI.sub.F) representing a would-be power increase of the mobile (225) and sets up two time windows. The source base-site (200) sends the measured and forecasted signal strengths to candidate target base-sites (205,210) found by the mobile (225) which measure the mobile (225) signal strength (RSSI.sub.T) and compare it once to RSSI.sub.S plus a hysteresis value. If RSSI.sub.T is greater than RSSI.sub.S, the call is transferred to the best responding cell. If RSSI.sub.T is below RSSI.sub.S, RSSI.sub.T is compared to RSSI.sub.F. During this time, the mobile 225 will increase power at the end of the first time window. If RSSI.sub.T is ever greater than RSSI.sub.F at any of the candidate target base-sites (205,210), the call is transferred to the responding target base-site (205,210). If the source base-site (200) receives no responses during the second time window, the process ends.

    摘要: A method and device for transmitting at least one short messaging service message to at least one wireless device are disclosed. The method comprises receiving at least one short message service message request associated with a short message service message. The short message service message is destined for reception by a wireless device (106). Prior to receiving the request, a short message service center (114) determines if a wireless device (106) is registered with a registrar (210) associated with a session initiation protocol network for communicating over a packet data network (102). The short message service message is transmitted to the wireless device (106) through the session initiation protocol network communicating over the packet data network (102) in response to the request and with the determination that the wireless device (106) is registered with the registrar (210).
