A method includes causing first reference information associated with a first cell or carrier and second reference information associated with a second cell or carrier to be sent to a first destination in a first time interval and causing at least third reference information associated with a third cell or carrier to be sent to a second destination in a different time interval.

Method and apparatus for reporting reference information with respect to multiple carriers or multiple cells

There is provided a mechanism for conducting data transmission from a network management entity of communication network control element to a terminal or UE with improved robustness. After a multiflow connection for data units via at least one network transceiver device and via at least two different paths is set up towards a terminal, selection criteria are applied so as to decide which data units are sent on which transmission path. Specifically, dependent on the applied selection criteria, data units of specific data are selected to be subjected either to bicasting each selected data unit using the at least two paths, or to dynamic flow switching so as to transmit each selected data unit using one of the at least two paths and wherein each selected data unit can be independently chosen to be transmitted over either of the at least two paths.

Data transmission mechanism with improved robustness using multiflow connection

A computer implemented method, computer readable medium and computing apparatus for distribution of network topology information in telecommunication networks comprising of a distribution of an information to a neighboring gateway node wherein the said information comprising an access node identifier, and a time validity indication of a network topology change, and wherein the said access node identifier is mapped to a serving gateway.

The present invention provides a method and respective entities for avoiding handovers in a ping-pong manner in a communication network. The method comprises comparing, when a handover of a mobile station to a base station is intended, decision criteria of the intended handover with decision criteria of previous handovers of the mobile station to that base station, and deciding on allowing or preventing the intended handover based on the result of the comparison.

Avoiding ping-pong handovers

A communications network for transferring communication frames between a base station and a plurality of subscriber stations. Each frame having sets of information and control messages, wherein at least some of the control messages allocate which set of information corresponds to which subscriber station. The overhead of the control messages being reduced.

Communications system

In a communication system in which mobile terminals may roam throughout an area with a plurality of base stations with overlapping coverages and wherein the base stations employ multiplexed slots all in the same frequency range, a system and method for allocating slots based on the quality classes of the transmitted traffic wherein certain slots are assigned as owned by some base stations and certain other slots are assigned as shared between base stations. Slots assigned as owned by a base station are assigned as avoided by adjacent base stations. When assigning a slot for communication from a mobile terminal, the number of slot quality measurements that must be made in order to find a slot with interference below an acceptable level is reduced, compared to conventional dynamic slot allocation schemes.

System and method for slot allocation with reduced need for measurement

The present invention relates to prioritizing special cells in cell selection in a cellular radio network. In a cellular radio network one or more cells provide a subscriber with special services or tariffs not offered to all subscribers. These cells are called subscriber's special cells. The mobile station measures an average reception level and calculates by means of them cell selection parameters on the basis of which the best cell is selected. In accordance with the invention, when the mobile station detects that the cell is one of cells of a special cell list stored in a memory, it checks first if the cell fulfils a minimum requirement of cell selection on the basis of the measured signal level. If the minimum requirement is fulfilled, the mobile station manipulates the calculation of the cell selection parameter of a special cell to the effect that the selection probability of a special cell is improved with respect to a normal cell. In a preferred embodiment of the invention, the manipulation of the calculation comprises a step of adding a predetermined margin to the measured signal level of a special cell before the cell selection parameter is calculated. This will minimize the possibility that the mobile station would accidentally be camped on a normal cell when it is within the area of a special cell.

Method for selecting cell in cellular network

A TDMA cellular radio system and a method of allocating available frequency bands to different cells in a TDMA cellular radio system wherein at least some of the receivers within the system use interference cancellation methods which cancel the effects of co-channel interference in a desired signal. To enable efficient use of interference cancellation and the resulting capacity increase in the system, the frequency bands available for the cellular radio system are allocated to different cells so that groups of adjacent service areas are formed in the system. Each group uses the same frequency band within the service areas, whereby at least one co-channel signal interfering with the desired signal is significantly stronger than other co-channel interfering signals.
