International Classification:

H04L012/28

US Classification:

370/391000, 370/328000

Abstract:

An apparatus and method provide MAC logic enabling the use of two or more reverse link rate controls at the same time in one or more sectors of a radio base station. That enables the base station to control reverse link loading via reverse link rate control, while assigning mobile stations to the type of reverse link rate control best suited to their needs. For example, the base station MAC logic may implement both a common rate controller that generates per-sector rate control commands, and a dedicated rate controller that generates per-user rate control commands and assign mobile stations having relatively lax reverse link service needs to the common rate controller, while assigning mobile stations having more demanding reverse link service requirements to the dedicated rate control. More than two rate controls can be implemented, and exemplary choices include per-user, per-sector, per-group, and scheduled rate control in any combination.

International Classification:

H04Q 7/24

US Classification:

370338000

Abstract:

A mobile communication network comprises a plurality of access nodes, wherein each access node allocates mobile station identifiers to mobile stations from an assigned group of mobile station identifiers. The mobile station identifiers in each group have a common property that identifies the corresponding access node. The mobile station identifier may be used, for example, to locate session information for a mobile station when a mobile station moves between access nodes.

International Classification:

H04L 12/66

US Classification:

370352000

Abstract:

In a mobile communication network comprising a plurality of access nodes, session information for a communication session is stored in one access node and may be requested by a peer access node. A requesting access node determines the location of session information based on the mobile station identifier associated with the communication session. If the session information is transferred to the requesting node, the requesting node may allocate a new mobile station identifier to the mobile station for the communication session.

Abstract:

A versatile system for controlling and managing resources for Soft Handoff Group operations is disclosed. The system determines which of a plurality of sectors in an access network is a serving sector for an access terminal. An active set of the plurality of sectors is assigned to the access terminal, comprising the serving sector. A soft handoff set for the access terminal is identified from the active set. A soft handoff group for the access terminal is identified from the soft handoff set. The access terminal's transmissions within the access network are managed according to the identified soft handoff group.

Abstract:

Systems and methods for transparent handovers of mobile relays on high-speed vehicles. In an embodiment, a base station of a wireless communications network transmits identification data to a mobile relay on a high-speed vehicle. The identification data identifies base stations which are configured for transparent handovers. The network also receives data indicative of a scheduled path of the high-speed vehicle, which it uses to select a target base station for communication with the mobile relay. Once the target base station has been selected, the network begins servicing the mobile relay from the second base station, without requiring any measurement values from the mobile relay and without handover signaling.
