  • Publication number: 20090215452
    Abstract: Efficient frequency assignment for mobile terminals in coexisting wireless communication systems is described herein. The coexisting wireless communication systems comprise a macro communication system and a localized communication system. Two prioritized lists are defined, a first list comprising a first entry relating to the macro communication system and the second entry relating to the localized communication system, the first and second entries each listing at least one common frequency. Based on the first list, a mobile terminal uses communication protocols associated with the localized communication system.

  • Publication number: 20090137249
    Abstract: Systems and methodologies are described that facilitate applying offsets and/or selectable hysteresis values to favor access points in cell reselection. In measuring and ranking surrounding access points in reselection, offsets can be applied to favorable access points to facilitate cell reselection thereto. The offset can positively affect measurements, and thus ranking as well, in some cases. Negative offsets can also be applied to lower measurements (and thus ranking) of some access points. Moreover, hysteresis values can be applied in measuring current cells to prevent frequent reselection. The hysteresis values can be selected based on a type of the current cell or related access point to expand the coverage area where desired. Thus, where the current access point is favorable, a larger hysteresis can be added to measurements related to the current access point.

  • Publication number: 20090129341
    Abstract: In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

  • Publication number: 20090093232
    Abstract: Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

  • Publication number: 20090092080
    Abstract: Providing for centralized access management to diverse types of mobile network access points is described herein. By way of example, network components can generate a system determination list (SDL) for a user terminal (UT) that is customized to access capabilities of the UT and/or current position of the UT. The SDL can be employed by the UT to determine which network access points to camp on, handoff to, or the like. The network components can include a network database that maintains UT subscriber and related home Femto cell information, or such information can be maintained at a network operator's home location register. In some aspects, the information can be obtained over the air from the UT or from a base station serving the UT.

  • Publication number: 20090092081
    Abstract: Providing for distributed access point management for access to a mobile network is described herein. By way of example, an interface application maintained at a Femto cell base station (BS) can facilitate initial power up and/or acquisition for a Femto user terminal (UT). Upon start-up, a bootstrap process is utilized by the Femto cell to provision the UT with an SDL establishing at least one BS as high priority within a particular geographic area (GEO). Thus, when the Femto UT is within the GEO, the UT is more likely to acquire, camp on and/or handoff to the preferred BS. When outside the GEO, a serving access point can provision the Femto UT OTA with a custom SDL suited to another GEO having a different high priority access point. By implementing access point management at distributed access points, expensive network equipment can be mitigated or avoided.

  • Publication number: 20080175263
    Abstract: A service for Public Safety (PS) and Law Enforcement (LE) users on commercial wireless networks which assure them access to packet data services. The service request is application based. The applications that are for official use, by the PS/LE users, could have a reserved priority level associated with them. The reserved priority level could be higher than a normal commercial user. The network could use the priority to distinguish users, and dynamically allocate and optimize network resources. The network could use priority level information to perform access, admission, and congestion control. The PS/LE user could use the official applications while on duty and un-official ones while off duty, thus, additionally freeing up network resources. The PS/LE users could then use advanced commercial packet data services, without the need for a private network, while at the same time making it feasible for commercial networks.
