  • Balancing paging load and tracking area updates
    Patent number: 8989744
    Abstract: A method for assigning a tracking area (TA) is disclosed. A mobility state of a wireless transmit/receive unit (WTRU) is determined and the TA is assigned based on the determined mobility state. Also disclosed is a method for accessing a closed subscriber group (CSG) TA.A CSG TA identifier is received at a WTRU and is stored. A CSG TA broadcast is received and the broadcast CSG TA is accessed if an identifier of the broadcast CSG TA matches the stored CSG TA identifier. Also disclosed is a method for changing a mobility state of a WTRU. A current mobility state of the WTRU is determined and a predetermined metric of the WTRU is examined. The predetermined metric is evaluated to determine if the metric has crossed a threshold and the mobility state is changed based on the evaluated metric.

  • SYSTEM FOR PERMITTING CONTROL OF THE PURGING OF A NODE B BY THE SERVING RADIO NETWORK CONTROLLER
    Publication number: 20150009938
    Abstract: A system and method which permit the RNC to control purging of data buffered in the Node B. The RNC monitors for a triggering event, which initiates the purging process. The RNC then informs the Node B of the need to purge data by transmitting a purge command, which prompts the Node B to delete at least a portion of buffered data. The purge command can include instructions for the Node B to purge all data for a particular UE, data in one or several user priority transmission queues or in one or more logical channels in the Node B, depending upon the particular data purge triggering event realized in the RNC.

  • WIRELESS COMMUNICATION METHOD AND SYSTEM FOR CONTROLLING DATA BIT RATES TO MAINTAIN THE QUALITY OF RADIO LINKS
    Publication number: 20140341067
    Abstract: A wireless communication method and system for controlling the current data bit rate of a radio link (RL) to maintain the quality of the RL. The system includes a core network (CN), a radio network controller (RNC) and at least one wireless transmit/receive unit (WTRU). The RL is established between the RNC and the WTRU. The RNC establishes a guaranteed data bit rate, a maximum data bit rate and a current data bit rate associated with the RL. When the RNC senses an event which indicates that the quality of the RL has substantially deteriorated, the RNC reduces the value of the current data bit rate. Then, in a recovery process, if a similar event does not occur during an established waiting period, the RNC restores the current data bit rate back to the maximum data bit rate.

  • CELL RESELECTION AND HANDOVER WITH MULTIMEDIA BROADCAST/MULTICAST SERVICE
    Publication number: 20140204829
    Abstract: A method and apparatus for providing wireless communication services, (e.g., multimedia broadcast multicast services (MBMS)), are disclosed. A wireless transmit/receive unit (WTRU) detects a plurality of target cell evolved Node-Bs (eNodeBs) that neighbor a serving cell eNodeB. The WTRU evaluates cell reselection criteria and determines a neighboring target cell eNodeB to reselect. The WTRU receives and reads master information block (MIB) and system information messages of the neighboring target cell eNodeB, and confirms that the determined neighboring target cell eNodeB is not part of a multimedia broadcast single frequency network (MBSFN). The WTRU identifies the neighboring target cell eNodeB to the serving cell eNodeB.

  • UPLINK POWER CONTROL USING RECEIVED REFERENCE SIGNAL
    Publication number: 20140194136
    Abstract: A user equipment (UE) includes circuitry configured to receive control information on a downlink control channel from a base station. The control information indicates an allocation of an uplink channel and the control information is sent in response to the base station determining that the UE is to send an adaptive modulation and coding report. The circuitry is further configured in response to the control information to transmit a communication in the allocated uplink channel in a time interval including at least one time slot. The communication includes an adaptive modulation and coding report, and a transmission power level of the communication is derived from the control information and a pathloss measured by the UE.

  • METHOD AND APPARTUS FOR SUPPORTING PAGING OVER AN HS-DSCH IN CELL_PCH AND URA_PCH STATES
    Publication number: 20140161076
    Abstract: A method and apparatus for paging a wireless transmit/receive unit (WTRU) in a CELL_PCH and URA_PCH states are disclosed. A WTRU may send an indication of an enhanced paging channel (PCH) capability of receiving a high speed downlink shared channel (HS-DSCH) in CELL_PCH and URA_PCH states, for example, in a CELL UPDATE message, a URA UPDATE message, or a UTRAN MOBILITY INFORMATION CONFIRM message. A drift radio network controller (DRNC) may receive an indication whether the WTRU has an enhanced PCH capability from a serving RNC and page the WTRU based on the indication. An RNC may page the WTRU over both an HS-DSCH and a PCH/secondary common control physical channel (S-CCPCH) if a WTRU capability is not known. The WTRU may monitor both an HS-DSCH and a PCH/S-CCPCH. The WTRU may configure reception over an HS-DSCH based on the capability of the SRNC or configuration from the network.

  • METHOD AND APPARATUS FOR IMPLEMENTING TRACKING AREA UPDATE AND CELL RESELECTION IN A LONG TERM EVOLUTION SYSTEM
    Publication number: 20140092871
    Abstract: The invention performs long term evolution (LTE) tracking area updates (TAUs), and tracking area code (TAC) and public land mobile network identification (PLMN-ID) assisted optimized wireless transmit/receive unit (WTRU) cell reselection. An evolved Node-B broadcasts system information including at least one system information block (SIB) based at least in part on an enhanced universal terrestrial radio access network (E-UTRAN) parameter response message sent by an evolved packet core (EPC) network. A WTRU generates a new TAC, which represents a tracking area identification (TA-ID) of a new cell, based on the system information, and compares the new TAC to an existing TAC, which represents a TA-ID of a previous cell. The WTRU transmits to the EPC network a TAU request message including the TA-ID of the new cell. The EPC network sends either a TAU accept message or a TAU reject message to the WTRU.
