  • Patent number: 8140074
    Abstract: A mobile communication network comprises a home agent supporting mobility of a mobile entity by generating bindings between a home address of the mobile entity and a care of address of the mobile entity. A mapping processor provides at least one set of mappings between a potential future care of address for a mobile entity and a real time characteristic criterion. The mappings may for example be determined in response to previous movements of the mobile entity in the communication network. A processor determines a real time characteristic and the home agent is arranged to change a binding between the home address and a current care of address in response to the at least one set of mappings and the real time characteristic, and without receiving binding updates from the mobile entity. The approach may allow support for mobility of a mobile entity while reducing signalling in support of mobility.

  • Patent number: 7983679
    Abstract: A communication system provides for an active handoff of a voice call between a packet switched network and a circuit switched network. An active handoff from the packet switched network to the circuit switched network is accomplished by multicasting the call over forward links of both networks during the handoff. An active handoff from the circuit switched network to the packet switched network is accomplished by multicasting the call over reverse links of both networks during the handoff. The former handoff further may be facilitated by routing the call for each network through a same packet data control switch, and the latter handoff further may be facilitated by routing the call for each network through a same mobile switching center. In order for a subscriber unit to operate concurrently in both networks, the subscriber unit may comprise multiple transceivers or a single transceiver that is rapidly switched between the networks.

  • Patent number: 7965683
    Abstract: A method and system for allocating a particular uplink control region to both HARQ ACKCH and CQICH in order to maximize uplink bandwidth for data transfer in a communication network. A control region scheduling (CRS) utility assigns a higher priority to HARQ ACKCH relative to CQICH. When both HARQ ACKCH and CQICH are to be allocated for a subscriber in the same region in the same frame, HARQ ACKCH is allocated in the region while CQICH is rejected. As the substitute to the rejected CQICH, the CRS utility may use current uplink channel quality information in combination with the corresponding HARQ ACK transmission to estimate the downlink channel quality information for the subscriber. Upon receiving the HARQ ACK information, the CRS utility updates the subscriber(s) uplink channel quality information. The CRS utility also provides a configurable option of activating or de-activating the sharing of the uplink control region.

  • Patent number: 7787421
    Abstract: A communication system provides for a handoff of a hybrid mobile station (MS) between a legacy network implementing a non-high rate packet data (non-HRPD) communication technology and a network implementing a high rate packet data (HRPD) communication technology. In one embodiment, the legacy network receives a handoff trigger and redirects the MS to the HRPD network. In other embodiments, the legacy network (or HRPD network) receives a handoff trigger, obtains an allocation of HRPD network (or non-HRPD network) resources from the HRPD network (or non-HRPD network), and informs the MS of the allocated HRPD network (or non-HRPD network) resources. Subsequent to the establishment by the HRPD network (or non-HRPD network) of a traffic channel with the MS, the non-HRPD network (or HRPD network) releases non-HRPD network (or HRPD network) RF resources associated with the MS. In still other embodiments, the handoffs may be controlled by a Mobile Switching Center.

  • Patent number: 7783315
    Abstract: To reduce a delay between a time that a user of an originating mobile station (MS) requests to set up a Push-To-Talk (PTT) call and the time that the user may begin to speak, a communication system provides a ‘wake up list’ of other mobile stations (MSs) that may be awakened prior to the originating MS requesting to set up a PTT call. To further reduce the delay, the user may begin speaking prior to completion of the call setup. The speech is stored and is conveyed to a called MS when the call is setup. If the call does not get setup or a user of the called MS is not present, the stored speech may be conveyed to the called MS as a voice message. The stored speech, or new speech, may also be used as an announcement of a call instead of the typical “beep” or “chirp.

  • Patent number: 7747017
    Abstract: A communication system provides a clear channel link for transport of encrypted payload across a network of the communication system. When a source access network receives, via an air interface, a frame that is formatted pursuant to an air interface protocol and that comprises encrypted payload, the source access network demultiplexes the frame to separate the encrypted payload and assembles an Intersystem Link Protocol (ISLP) frame that comprises the encrypted payload. The source access network adds a link layer header to the ISLP frame that identifies one or more of frame type information and a sequence value associated with the frame and conveys the ISLP frame and added header across the network, for example, to a destination access network. Based on the added header, the source and destination access networks are able to perform clear channel synchronization.
