Abstract: The present invention relates to a method and apparatus for controlling a connection transfer in a cellular network having at least two systems, such as a GSM system and a WCDMA system. Based on a load determination, a service-based inter-system or inter-frequency handover of the connection to another system or to another carrier of the same system is initiated if the determined is below a threshold and service priorities are indicating it. If it exceeds the threshold, an additional load-based inter-system or inter-frequency handover can be initiated. If the load of the target cell is not known, a load estimation based on a learning process can be used to derive a probability of success of an interfrequency or inter-system handover, which may be used for deciding on the initiation of the inter-system handover. The learning process may be performed by evaluating preceding interfrequency or inter-system handovers to the target cell or preceding interfrequency or inter-system handovers from the target cell.

Abstract: Signal strength measurements for different frequencies in different cells are calibrated in a cellular communications system. The signal strength of first and second frequencies in at least one cell of a plurality of cells is repeatedly measured. A measurement history is created for said first and second frequencies in at least the one cell. Each measurement history is based on the signal strength measurements of one of the first and second frequencies in the respective one cell. The measurement histories are stored. A respective correction factor is determined for each possible pair of first and second frequencies in at least the one cell. Each correction factor is based on the stored measurement history of the first and second frequencies in the pair. The respective correction factor for a pair of first and second frequencies cell is applied when comparing the signal strength measurements of the first and second frequencies in said pair.

Abstract: A method and system for uplink interference avoidance that includes a network device and mobile device in a communications network. A signal characteristic of a downlink channel currently not used by the mobile device is measured to determine if the signal characteristic has increased or decreased. The signal characteristic increase or decrease is reported to the network device. The signal characteristic may be, for example, signal quality or signal strength. The interference may be, for example, adjacent channel leakage power ratio (ACLR) interference. A handover from the downlink channel currently used by the mobile device is launched thus avoiding interference in an uplink channel not currently used by the mobile device. An inter-frequency handover or an inter-system handover may be launched.

Abstract: A method and system for soft handover detection for uplink interference avoidance that includes a network device and mobile device in a communications network. The mobile device uses a downlink carrier. A parameter, such as a signal strength or a signal quality, of the downlink carrier and one of a co-sited downlink carrier or neighboring downlink carrier is measured. A soft handover area is detected by the network device or the mobile device based on comparing the signal strength or the signal quality of the downlink carrier with the signal strength or the signal quality of one of the co-sited downlink carrier or the neighboring downlink carrier. The downlink carrier, the co-sited downlink carrier or the neighboring downlink carrier may be from a core band, (e.g., 2.0 GHz), or extension band, (e.g., 2.5 GHz), of frequencies or combination thereof. The system provides for handovers while uplink carrier interference is avoided.

Abstract: A method and system for soft handover area detection for uplink interference avoidance that includes a network device and mobile device in a communications network. A trigger criteria threshold is determined for the mobile device. The mobile device is using a downlink carrier. If a trigger criteria has risen above or fallen below the trigger criteria threshold, inter-frequency measurements of co-sited cells are performed and compared to determine if a soft handover area exists. Co-sited cells are searched for downlink carriers and reselection is initiated from the downlink carrier to a co-sited cell downlink carrier if the co-sited cell downlink carrier is useable by the mobile device. Reselection is initiated from the downlink carrier to a non co-sited cell downlink carrier if no co-sited cell downlink carrier useable by the mobile device is found. The system provides for reselection while uplink carrier interference is avoided.

In response to the request, the physical layer of the uplink connection is maintained while changing the downlink frequency from the first downlink frequency to the second downlink frequency.

Abstract: A method and system for cell identification for uplink interference avoidance that includes a network device and mobile device in a communications network. Inter-frequency measurements are performed by a mobile device on a downlink carrier currently not used by the mobile device.

A cell is identified based on the second measurements. The inter-frequency measurements may include receive signal strength indicator (RSSI) measurements, received signal code power (RSCP) measurements, or average channel power-to-total signal power ratio (Ec/Io) measurements. The second measurements may include signal quality measurements.

Abstract: A method and apparatus for selection of downlink carriers in a cellular system that includes selecting a first downlink carrier for use by a mobile node. A decision is made that the mobile node should use another downlink carrier. The mobile node is then directed by a network node to use a second downlink carrier. The first downlink carrier and second downlink carrier may be from different cells or the same cell supplying downlink frequencies. The network node may decide that the mobile node should use another downlink carrier based on several factors such as current load conditions of the cells supplying the first downlink carrier and the second downlink carrier, a type of service on the current downlink carrier, whether the mobile node has connection capability at frequencies of the second downlink carrier, or if a potential interference condition may exist.
