Patent number: 8605704Abstract: Methods enable a paging service and a media service to be carried on a single carrier frequency. The methods includes: determining to send a paging record to a communication device for a first media service, wherein the first media service is provided on a first carrier frequency; inserting the paging record into a first message generated using a protocol that is also used to provide a second different media service to the communication device on a second different carrier frequency; providing a paging indication using the protocol; and sending the paging indication and the first message with the paging record over the second carrier frequency. The protocol can be a multimedia broadcast service (MBMS) protocol. The paging indication alerts the communication device to monitor the second carrier frequency for the paging record.Type: GrantFiled: December 23, 2008Date of Patent: December 10, 2013Assignee: Motorola Mobility LLCInventors: Satish Nanjunda Swamy, Padmaja Putcha, Sandeep V.

Patent number: 8126475Abstract: A network controller or base station (502), allocates resources and indicates a minimum priority level below which, mobile stations may not transmit data via messaging (503). Messaging (503) may be a scheduling message in some embodiments. The network controller or base station (502) also communicates a data timer setting for timing sub-minimum priority data via messaging (505). Messaging (505) may be a control message in some embodiments. The mobile station (501) responds by setting a data timer (507) and holding data with a priority below the specified minimum. Before the timer times out, the mobile station (501) may transmit data on granted resources via (509) provided its priority level is above the specified minimum. After timer expiration, the mobile station (501) may transmit its low priority data, or combinations of high and low priority data (511).Type: GrantFiled: October 9, 2006Date of Patent: February 28, 2012Assignee: Motorola Mobility, Inc.Inventors: Ravi Kuchibhotla, Padmaja Putcha

Patent number: 8018895Abstract: Mobile station applications (419) may include an SI unit (409) for piggy backing SI onto data stored in data buffer (421) and also for adding an indicator to the SI information. The scheduling information and/or incremental control information (501) is piggy backed onto a data PDU and also has a sequence number (503) and an indicator field (505) which is added by the SI unit, such as SI unit (409), in accordance with the embodiments. The indicator may be a bit map having four bit positions. A bit position having a binary “1” value may be utilized to indicate that a previous SN of SI information remains valid. For example, “0100” of the bit map sequence may indicate that SN #3 is still valid. The base station or controller may then determine whether to implement or discard an SI information having the indicated SN.Type: GrantFiled: November 30, 2006Date of Patent: September 13, 2011Assignee: Motorola Mobility, Inc.Inventors: Ravi Kuchibhotla, Padmaja Putcha

Patent number: 7836294Abstract: A security mode method (200) receives (210) a layer 3 message in a first domain from a network, determines (220) if the layer 3 message has integrity protection information, ascertains (240) if a security mode has been initiated in the first domain, and forwards (260) the layer 3 message to an upper layer, if the layer 3 message lacks integrity protection information and a security mode has not been initiated in the first domain even if security mode has been initiated in a second domain. This method allows a mobile station to process a non-integrity-protected layer 3 message from one domain even if integrity protection has been initiated in another domain. When packet-switched and circuit-switched connections are being concurrently set up, a non-integrity-protected message in one domain may arrive at a mobile station after an integrity protection initiation message in another domain.Type: GrantFiled: August 8, 2005Date of Patent: November 16, 2010Assignee: Motorola Mobility, Inc.Inventors: Hui Zhao, Padmaja Putcha

Patent number: 7821975Abstract: A wireless communication terminal (300) including a radio transceiver (320), and a radio link control entity (310) that re-initiates a radio link control reset procedure when the transceiver receives a message containing an instruction to change an uplink or downlink protocol data unit size during an ongoing radio link control reset procedure. For example, the radio access network may initiate an uplink or downlink PDU size change before terminal receives acknowledgement that a previously initiated radio link control reset procedure is complete. The radio link control entity restarts a radio link control reset timer upon re-initiating the radio link control reset procedure after re-establishing radio link control.Type: GrantFiled: June 10, 2005Date of Patent: October 26, 2010Assignee: Motorola, Inc.Inventors: Richard C.
