Abstract: Techniques to mitigate inter-cell interference using joint time and frequency division are described. A frequency band is divided into multiple non-overlapping frequency subbands. The transmission timeline is divided into Tin and Tout time intervals. Data is exchanged with users in at least one inner region of a cell on the entire frequency band in the Tin time intervals. Data is exchanged with users in multiple outer regions of the cell on the multiple frequency subbands in the Tout time intervals. The frequency band may be partitioned into three frequency subbands. Data may then be exchanged with users in first, second and third outer regions on first, second and third frequency subbands, respectively. The regions in which the users are located may be determined based on pilot and/or other measurements.

Abstract: A base station is capable of performing a method for scheduling in a wireless communication system. In the method, a downlink channel measurement value received from a terminal is compared with a threshold. When the downlink channel measurement value is smaller than the threshold, an activation set for a handover of the terminal is determined. When the number of base stations inside the activation set is two or more, a Modulation and Coding Scheme (MCS) level is allocated to the terminal with consideration of the downlink channel measurement value. A wireless resource is allocated to the terminal with consideration of the allocated MCS level and a headroom of the terminal.

Abstract: Techniques for selecting a radio interface for an application are described. A terminal identifies locally-addressable and globally-addressable wireless networks among wireless networks available to the terminal. Radio interfaces supported by the terminal may be prioritized based on the locally-addressable and globally-addressable wireless networks, information obtained for the application, the application type, etc. Different applications may have different radio interface preferences or requirements, which may be considered in prioritizing the radio interfaces. A suitable radio interface may be selected for the application based on the prioritized radio interfaces. WLAN interface may be selected for the application if (a) the WLAN interface is preferred and any WLAN is acceptable to the application or (b) a globally-addressable WLAN is available. A WLAN interface may be selected for the application if a globally-addressable WLAN is not available.

Abstract: A technique for protecting location information of a subscriber in a mobile network is disclosed. A User Mobility Server (UMS) receives a first query from a first call state control function (CSCF). The UMS transmits a call setup and a subscriber identity to a servicing-call state control function (S-CSCF). The S-CSCF may have no record of the subscriber identity due to a restart are some other event. The UMS receives a second query from the S-CSCF based in part of the subscriber identity. The UMS transmits a home address of a mobile station to the S-CSCF. The UMS may also transmit a profile download to the S-CSCF.

Abstract: A wireless communication system is provided for rapidly establishing the QoS resource on different communication networks. In this system, the NAP evaluates a network resource used by the MT, and generates the QoS history information unit indicating the evaluation result. The AAA authenticates the QoS history information unit generated by the NAP. The NAP transmits the authenticated QoS history information unit to the MT. The MT request for a resource establishment to the NAP when switching the communicating party from the NAP to the NAP, and transmits the QoS history information unit. The NAP verifies the authenticity of the QoS history information unit to the AAA when receiving the request for resource establishment from the MT and allocates the network resource to the MT based on the QoS history information unit.

Abstract: A mobile device automatically is configured to the emergency alert system (EAS) channel utilized by the cellular site from which the mobile device registers with a network. In an example configuration, an EAS server provides a mobile switching center (MSC) configuration information regarding the emergency alert channels to be used for the cellular sites supported by the MSC. When the mobile device registers via a cellular site supported by the MSC, the designated channel to be used for EAS messages is sent to the mobile device as part of the registration process. The mobile device assigns an internal channel to the designated channel. In another example configuration, the mobile device is preconfigured with a table listing all possible EAS channels, and the MSC provides, during the registration process, a pointer to the appropriate portion of the table.

Abstract: Systems and methods for Walsh code assignment are provided. In accordance with the disclosed exemplary embodiments, when a set of mobile communication units (MU) is in a control/hold state, instead of a base transceiver station (BTS) assigning Walsh codes for respective dedicated control channels (dcch ) to the set of mobile communication units (MU) on a one-to-one basis, the base transceiver station (BTS) circulates the Walsh codes among the set of mobile communication units (MU). Thus, at a given time, the base transceiver station (BTS) has assigned the available Walsh codes to only a subset of the mobile communication units (MU) in the control/hold state. Accordingly, this Walsh code assignment allows the system to support more mobile communication units (MU) in the control/hold state.
