Method and system to support fast hand-over of mobile subscriber stations in broadband wireless networks

Method and system to support fast hand-over of mobile subscriber stations in broadband wireless networks. In connection with a hand-over process, a determination is made to which target base station (BS) an air interface for a mobile subscriber station (MSS) is to be handed-over. Various service requirements are requested by the MSS, including a Quality of Service (QoS) level. Based on feedback from potential target BSs, a target BS for hand-over is selected.

In one embodiment, a Management Information Base (MIB) instance is maintained at each BS in a broadband wireless network. To pre-provision service, applicable connection context data are transferred between MIB instances at the serving and target BS using Simple Network Management Protocol (SNMP) messaging.

Preventing degradation of AGC action in user equipment by inter-cell interference in wireless broadband networks

A measurement pattern for at least one automatic gain control tracking loop in a user equipment device is determined, when resource restrictions have been applied to the user equipment device, the resource restrictions comprising at least one measurement restriction pattern. Then automatic gain control measurements are performed by the user equipment device according to the measurement patterns of the at least one automatic gain control tracking loop. AGC measurements are thus in effect gated according restriction patterns (tables 1 - 5). Fig.2 illustrates the general principle of performing AGC tracking per sub-frame set, with measurements and their application separated in time (arrows). Measurements may be taken during muted subframes, e.g. almost blank subframes (ABS).

Method and Device in a Telecommunications System

In a method in a central node of a cellular radio network the central node is adapted to deciding if a mobile station connected to the cellular radio network via a first radio access technology controlled by the central node is to be moved to another radio access technology when a circuit switched call of the mobile station is ended. It is assumed that the cellular radio network is adapted to use a fallback to circuit switched procedure. First it is decided that a CS call for a particular mobile station has ended. Then in it is checked if the CS call was the result of a fallback to CS procedure. The central node then decides if the mobile station is to be moved to another radio access technology based at least partly on the, i.e. if the CS call was a result of a CS fallback procedure.

Cell reselection process for wireless communications

A method of cell reselection in a wireless communications system where parameters are transmitted by the network in system information blocks to WTRU's on the network. Parameters are either added or subtracted from an equation representing the signal level and/or quality of a cell. Parameters may be prioritized. The results of the calculations are used to rank the servicing cell and neighboring cells. If a neighboring cell has a higher quality than the servicing cell, then the WTRU reselects the better cell. The network may transmit a blacklist of cells where the WTRU cannot camp as well as a barring timer for each cell where if the timer expires, the cell can again be considered for reselection. Information germane to the reselection decision may be transmitted and used by the network.

A method for handing off handset in a mobile communication network that defines at a base station ( 110 ) an adjusted handover boundary ( 106 ) different from a default handover boundary ( 104 ) between the base station ( 110 ) and a different base station ( 116 ). Handover adjustment parameters can be conveyed ( 120 ) within messages to user equipment (UE) ( 112 ) within range ( 124 ) of the base station. The handover adjustment parameters can provide specifics for handover permitting the user equipment (UE) ( 120 ) receiving the messages to perform handover operations ( 166 ) in accordance with the adjusted handover boundary ( 106 ) instead of the default handover boundary ( 104 ). The handover adjustment parameters can increment the cell individual offset (CIO) ( 212 ) when adjusting for “too late” ( 210 ) handover conditions. The handover adjustment parameters decrease the cell individual offset (CIO) ( 222 ) when adjusting for “too early” ( 220 ) handover conditions.

Scell radio link monitoring and radio link failure handling

A method of radio link monitoring (RLM) and radio link failure (RLF) handling over a secondary serving cell (SCELL) is proposed. In a wireless network, a user equipment (UE) establishes a radio resource control (RRC) connection with a base station (eNB). The UE applies carrier aggregation for multiple component carriers (CCs) configured as multiple serving cells. The UE performs radio link monitoring over a primary serving cell (PCELL). The UE also performs radio link monitoring over a secondary serving cell (SCELL). The SCELL belongs to a CC group of one or more CCs, and used as a reference cell for the CC group. When SCELL performance is below pre-defined criteria, the UE and the eNB apply certain actions over the SCELL or all CCs in the CC group. The proposed SCELL RLM/RLF handling prevents spurious and uncontrollable uplink SCELL transmission and interference to other UEs.

Controlling mobility in cellular networks

A cellular basestation can select its own mobility parameters in order to achieve desirable effects in terms of the overall network performance. When a cellular basestation forms part of a group of such basestations on a single local area network, it can receive information from the other basestations in the group, for example relating to the loading on the other basestations, and can use this information in order to set mobility parameters. Where the basestation receives loading information from other basestations in the group, it can set mobility parameters so that a user equipment device becomes less likely to select a more highly loaded cell, and more likely to select a less highly loaded cell.

Wireless offloading provides tools to a service provider to encourage or direct a subscriber to offload from a first network, e.g., a cellular network, to a second network, e.g., a Wi-Fi network. The cellular service provider can use network data to determine wireless offloading priorities for cellular subscribers on an individual or group basis. The cellular service provider may use wireless network data it has and/or wireless network data it learns about networks from the wireless devices (which may obtain Wi-Fi network data from beacon frames of Wi-Fi networks or active scanning and which may report to the cellular service provider). Each wireless device can be given scanning assignments to ensure that the reporting task is shared among subscribers or adjusted to fill in gaps in data. With the network data, the cellular service provider is capable of generating useful prioritized network lists for wireless devices, either individually or as a group. Preferences can be encouraged in the form of incentive offers to subscribers to, e.g., offload from the cellular network to a Wi-Fi network. Incentive offers can include offers to lower service costs or provide additional or improved services.
