Patent number: 7085575Abstract: 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).Type: GrantFiled: August 18, 2003Date of Patent: August 1, 2006Assignee: Motorola, Inc.Inventors: Jean-Aicard Fabien, Amitava Ghosh, Rapeepat Ratasuk

Patent number: 7076265Abstract: 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.Type: GrantFiled: September 26, 2003Date of Patent: July 11, 2006Assignee: Motorola, Inc.Inventors: Daniel R.

Patent number: 7043198Abstract: 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.Type: GrantFiled: September 6, 2002Date of Patent: May 9, 2006Assignee: Motorola, Inc.Inventors: Duke Edward Hanson, Thomas Peter Emmons, Jr., Robert Anthony Peters, James William Startup, Peter Monsen, Norbert Kleiner

Patent number: 7043249Abstract: 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.Type: GrantFiled: November 13, 2002Date of Patent: May 9, 2006Assignee: Motorola, Inc.Inventor: Shahab M. Sayeedi

Patent number: 7031273Abstract: 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).Type: GrantFiled: April 23, 2004Date of Patent: April 18, 2006Assignee: Motorola, Inc.Inventors: William N.
