  • Patent number: 7187759
    Abstract: A voice mail method screens calls made by a calling subscriber (10) to a called subscriber (20) which is unavailable (or otherwise screening calls). The screening method determines (110) whether the called subscriber (20) has a voice mail screening feature. An internet protocol multi-media system (50) receives the call from the called subscriber (114). The internet protocol multi-media system then transfers call control to a voicemail screening server which plays subscriber (20) the beginning of the voicemail message being left by subscriber (10) and offers to-route the call back to the called subscriber (20). The called subscriber then indicates via a short code whether the called subscriber will accept the call (124).

  • Patent number: 7149515
    Abstract: Transcoding needs and selection are performed by a central call control function (17, 35). Each transcoder (18, 23, 34, 36) registers with the appropriate call control (17, 35). The call control then determines whether a vocoder is required at all. If vocoding is required, call control (17, 35) selects the appropriate transcoder (18, 34) and inserts the appropriate transcoder into the bearer traffic stream (16).

  • Patent number: 7103809
    Abstract: A method for selecting (64) a server (30, 40 or 50) is based upon an available server capacity indication (66) for each of the servers. A server may become faulty. Repeated attempted selection (63) of a faulty server exponentially decreases (70) the probability of selecting the faulty server. The method performs a ratio of a currently available capacity for each server of a pool of servers to the total available capacity for all the servers in the pool (64). The server capacities for the pool of servers are dynamically changed (68, 70).

  • Patent number: 7085575
    Abstract: In a mobile telecommunication system (10), a number of user equipments (40–45) may receive multimedia broadcast multicast services. The method for power allocation and user assignment for MBMS services determines any number (K) of user equipments which may be served without complete cell area coverage (78). For more than K user equipments (40–45) requesting MBMS services, dedicated channels are assigned (84). For user equipments requesting MBMS service during a broadcast, such user equipment is assigned to the channel (broadcast or dedicated) with the lower power requirement, if power is available. If the user is assigned to the broadcast channel, and power is available, power of the broadcast channel is adjusted (108). Otherwise, the power of the broadcast channel is increased and no further power is indicated as being available (112).

  • Patent number: 7076265
    Abstract: A mobile unit 40 which is in a soft handoff condition 50 with a base station (32) has the power transmitted by the base station (32) on the mobile link (52) controlled. The base station (32) determines (70) when a frame erasure count reaches a particular level N. The base station then places this link in a clamped state (72) at minimum power. When the base station determines that M consecutive good frames have been received (92), the base station restores the link (52) to a normal state (94). A recovery arrangement (100, 110 and 120) prevents clamping by all base stations (32–34) and loss of the link.

  • Patent number: 7058407
    Abstract: A controller (102) in a fixed network of a wireless data communication system (100) transmits an indication that a diversity transmission of the information stream is available. When predetermined capabilities of a user equipment (112) and the fixed network are sufficient to allow soft combining of a primary transmission and the diversity transmission of bits of the information stream in the user equipment, the controller further transmits primary and diversity transmissions in a manner that facilitates soft combining in the user equipment, and transmits a group identity of the information stream to indicate that the information stream is in the primary and diversity transmissions.

  • Patent number: 7043249
    Abstract: A packet data serving node (106) initiates a packet data session update procedure with the RAN by passing a session update message containing packet data session parameters associated with at least one packet data service to a packet control function (111) which may be part of a radio access network (110). The session parameter may include a packet data service inactivity timer, QoS parameters, user information or any other session related parameters. Packet control function (111) examines the PSDN code and inhibits tearing down the link (A10/A11) between PCF (111) and PDSN (106). Further, if a handoff occurs, the BS passes the packet data session parameters associated with each of the service instances to the MSC that in turn passes them on the target BS of the handoff.

  • Patent number: 7043198
    Abstract: The present invention utilizes a dual polarization reception system (200) that utilizes the energy available in orthogonal polarizations to effectively increase link margin, thereby allowing for adequate signal quality reception in difficult environments. A co-polarized and a cross-polarized signal are separately downconverted and demultiplexed. The signals from each demultiplexed output are then sampled and weighted. The weighted samples for each polarity are combined in soft decision combining/decoding circuitry (255, 360), and this circuitry determines the most likely state of a received symbol's transmitted value.

  • Patent number: 7031273
    Abstract: For a network server (35) communicating with a wireless unit (10) via a Session Initiation Protocol, a retransmission method (50) first sets a timer based upon a time likely for a mobile unit to respond (54). Then the network server waits for a response (56). When the timer set for the kind of mobile unit being used expires (64), a retransmit of the original SIP request takes place (68). Optionally, modes for waiting may include a linear mode (72) and an exponential mode (74).
