Abstract: This invention describes a new methodology for a cell reselection by a mobile station (MS) for improving network interconnection and interoperability in a limited mobile access environment. The invention is applicable to any kind of networks and their interconnections. The invention describes how the MS can better recover from failed intersystem cell reselection attempts so that there are fewer subsequent failed attempts using two major improvements. First, the MS takes into consideration during cell reselection evaluation and candidate-cell selection, whether the MS had previously been unsuccessful in reselecting the considered cell. This means treating neighbor cells to which the MS had failed reselection before with a lower priority in subsequent cell reselection evaluations. Second, the MS is allowed to stop monitoring and thus, to stop evaluating cells if it was earlier found that the access to those cells is forbidden.

Abstract: Techniques are provided for reducing the likelihood of missed pages during cell reselection. For cell reselection with early camping, a terminal determines that reselection from a first base station to a second base station is required. The terminal then performs cell reselection and receives sufficient system information to process a paging channel for the second base station. The terminal starts monitoring the paging channel upon receiving this information and prior to completing the cell reselection. For cell reselection with reconfirmation, the terminal receives and decodes a control channel for the second base station prior to performing cell reselection. For cell reselection with overlapping page reception, the terminal monitors the paging channel for the first base station until a terminating event occurs and starts monitoring the paging channel for the second base station upon receiving sufficient system information. The monitoring of the two paging channels overlaps in time.

Abstract: In a base station providing a large-distance service area (large area) such as a mobile communication system WLL of the CDMA method, the time required for performing call search (path search) is reduced so as to reduce the call connection time. When performing a path search in the base station (8), a predetermined offset value from a reference time is set so that path search is performed only in a doughnut-shaped service area (30). Thus, there is no need of performing path search in the vicinity of the base station (8) and search is performed only in the doughnut-shaped service area (30). Thus, it is possible to reduce the path search time and reduce the call connection time.

Abstract: Disclosed is a method of controlling a transmit power constraint at a mobile station using a pilot power ratio (PPR) or other measurement of relative received powers (or signal strengths) between a neighbor cell transmission and a serving cell transmission such that other-cell interference produced by the mobile station may be managed. The transmit power constraint may, for example, correspond to a total or per sub-carrier maximum allowable mobile station transmit power. The transmit power constraint may be decreased if an adjacent neighbor cell, or an adjacent neighbor cell with a strongest pilot signal strength at the mobile station, is interference overloaded, i.e., interference levels in the adjacent neighbor cell is above a threshold interference level. Such decrease may be based on a pilot power ratio between a received pilot power of the overloaded adjacent neighbor cell at the mobile station and a received pilot power of the serving cell at the mobile station.

Abstract: For cell measurement, a wireless device categorizes cells whose identities are known to the device into multiple sets. The wireless device may obtain these cells from the system via signaling and/or detect these cells via searches. Different sets of cells may be associated with different levels of importance (e.g., for handoff), require different amounts of processing for measurements, and so on. Each set is associated with a particular measurement rate. Cells deemed to be more important (e.g., for handoff) are measured more frequently. Cells deemed to be less important and/or require more processing for measurements (e.g., cells with unknown timing) are measured less frequently. The wireless device performs searches and makes measurements for the cells in each set at the measurement rate selected for that set.

Abstract: A method for providing a multicast service from a macrocell or a microcell to a mobile station in a mobile communication system having a hierarchical cell structure in which a given area is divided into at least one macrocell and at least one microcell overlapping with each other. The mobile station receives a multicast service by accessing the macrocell or the microcell according to a carrier-to-interference ratio (C/I) for the multicast service measured in a macrocell area and according to an existence or non-existence of a concurrent call currently in service.

When the cable is physically installed (for example, in the wall or ceiling of a building) for the other purpose, the access points are simultaneously physically installed. The access points so installed can then be activated and used as part of a wireless network.

The statistics of each cell are evaluated based on a given ranking criteria. Based on the evaluation, the cells of the grouped are ranked, with a highest ranked cell being deleted from the network design based on the ranking criteria. The method may enable the selecting of desired cells for deletion, either during site selection of a design for an initial network deployment, or for a network overlay and upgrade of an existing network, in an effort to reduce cell count while maintaining a desired cell coverage in the network.

Abstract: Air interface management apparatus for use in network-based control of measurements made by mobile user equipment with respect to cells of the network is adapted to detect conflict in content of measurement control messages instructing the report of pathloss measurement values. Conflict is detected in particular where the message specifies: a) an identity for a triggering event for which the category or categories of cell to be measured is determined at the receiver solely by said identity and comprises detected set cells, or b) periodical measurement in respect of a detected set cell. Pathloss measurements are not possible in these cases. The apparatus provides a mechanism for dealing with detected conflict by blocking transmission of, or response to, a measurement control message giving rise to conflict. Alternatively, the message or the response may be modified to avoid the conflict.

Abstract: A method for dynamically locating a wireless TCP proxy in a routing path in a wired/wireless integrated network is provided. A proxy for a mobile host transmits a proxy change request to a first higher-level proxy if a mobility of the mobile host is larger than a mobility threshold that is preset in the proxy. The first higher-level proxy determines whether the mobility of the mobile host is larger than a mobility threshold that is preset in the first higher-level proxy. The first higher-level proxy transmits a proxy change request packet to a second higher-level proxy if the mobility of the mobile host is larger than the mobility threshold of the first higher-level proxy. The second higher-level proxy selectively permits the proxy change if the mobility of the mobile host is smaller than the mobility threshold of the second higher-level proxy.

Abstract: A method for providing a local cordless-type service comprises the steps of receiving subscriber neighborhood zone selection input so that a mobile telephone equipped subscriber may place or receive calls for a fixed rate, for example, per month without having to pay radio frequency air time charges any time they are located within their selected subscribed-to zones. If the subscribed-to zones are adjacent to one another and the mobile subscriber roams from one zone to another, the subscriber may continue their free call uninterrupted and without paying air time charges. However, when the subscriber roams outside their subscribed-to zones they may be switched from the present local cordless-type services to conventional personal communications services and pay air time charges. However for an active call, no air-time charges are incurred as the user transitions between the cellular/DPCS environment and the local cordless service environment.

A micromobility network includes routers connected in a tree connection and radio base stations connected to the routers in the lowest layer such that an updating notification of a route from a mobile terminal is repeated in order from a radio base station to successive higher order routers to update the route and a packet is distributed along the updated route. In the mobility network, directly lower order routers to each router are numbered to the numbers 1 to n with reference to the direct lower order router accommodation number n, and a route from the radio base station to the router in the highest layer represented by a route number composed of the numbers of the thus numbered routers is applied to the radio base station.

Abstract: A hierarchical cell structure (HCS) cellular communications system includes a macro cell encompassing a smaller micro cell that employ the same frequency band. The macro cell includes a macro cell base station, and the micro cell includes a micro cell base station. An uplink communication cell boundary between the macro cell and the micro cell is established, and a downlink communication cell boundary between the macro cell and the micro cell is established. A radio network controller determines whether a condition exists in the HCS system which indicates that the uplink and downlink micro cell boundaries should be unbalanced. If the condition is met or exists, the power and/or antenna beam tilt of a downlink transmission from the micro cell base station is reduced to unbalance the uplink and downlink micro cell boundaries. Alternatively, the radio network controller may employ an offset value to mathematically reduce mobile detected pilot power levels associated with the micro base station.

Abstract: Infrastructure network service measurements are used to determine sector capacity, or the like, in a wireless network. The embodiments use a linear regression to predict current usage and/or capacity of the radio-frequency link resources between wireless subscribers and wireless base stations, for example, as an indication of when the link is incapable of supporting additional subscribers. The determination of resource capacity can be refined down to the sector-carrier level (a single carrier within a base station sector). The prediction can be cast in terms of time, which allows network service providers to plan the growth of their base stations to meet subscriber needs. Metrics derived from the regression, such as line slope, also provide useful information about usage and performance.

Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.
