A user equipment performs a method for evaluating a need for handover between cells in a cellular network. The method includes estimating the risk of making an ineffective handover, and, when said estimated risk is above a threshold, changing the value of at least one handover trigger parameter so as to reduce the future risk of ineffective handover.

Method of controlling handover by user equipment

A method of communication between a base station and a user equipment in a cellular network includes providing, from the base station to the user equipment, a new allowed maximum transmitting power lower than a former allowed maximum transmitting power because of a traffic load increase within the base station cell. If the user equipment later sends a message to the base station, with a transmitting power exceeding the new allowed maximum transmitting power, the base station may decide not to reject user equipment's message depending on at least one condition.

Method of communication in a cellular network between a base station and a user equipment

An apparatus and process is provided for handling downlink transmissions to a user equipment (UE) from a service provider wherein the UE is adapted to be associated with two subscriber identity modules (SIMs). The two SIMs are associated with a first communication network and a second communication network such that the UE can request a switch of downlink data via the first communication network to the second communication network.

Handling of downlink IP packet transmission switching on dual SIM UE

The invention deals with a method of communication in cellular networks comprising mobile user equipments (), base stations () and core networks (), backhauls () between base stations () and core networks (), including, if a request from or to a mobile user equipment () cannot be satisfied by a base station () of a first network through own backhaul according to traffic load thereon, the step of trying to satisfy said request through backhaul of another neighbor base station () of a second network different from first network, said another neighbor base station () being selected according at least to availability and to offered quality of service thereof.

Communication in a cellular network taking into account backhaul loading

A method of configuration of an e-Node B device, on order to integrate the e-Node B device in a telecommunication network, comprising the following steps, performed by the e-Node B device: &#x2014;entering a user equipment mode, &#x2014;establishing a communication link with the telecommunication network, &#x2014;receiving configuration data, &#x2014;self-configuring using the received data, and &#x2014;entering an operational state, wherein the establishment of the communication link comprises transmitting a data element indicating that the establishment of the communication originates from an e-Node B behaving as a user equipment.

Self-configuration of an E-node-B

The invention relates to a handover method for redirecting an ongoing communication of a connected cellular device (UE) from a serving cell (SRV_C) to a target cell (TGT_C). Both cells (SRV_C, TGT_C) belong to a network. The method comprises receiving, in the connected cellular device (UE), a cell attenuation measurement, a supplemental hysteresis parameter which value depends on the load of the target cell (TGT_C), and a threshold parameter. The method comprises comparing, in the connected cellular device (UE), an additive combination of the cell attenuation measurement, of a hysteresis parameter and of the supplemental hysteresis parameter with the threshold parameter. The method comprises sending, from the connected cellular device (UE), a measurement report to the network, if the result of the comparison remains positive during a given duration. The invention also relates to a cellular device (UE) and to a computer program implementing the aforementioned method.

Enhanced handover procedure

A method and device for assigning a cell to a wireless communication apparatus, and corresponding apparatus is provided. The method for assigning a cell to a wireless communication apparatus is performed when the wireless communication device leaves a standby mode so as to send a request for access to a desired service belonging to a class of services. The method may include elaborating, for each cell and for each class of service supported by the cell, an index relating to the loading rate of the class of services within the cell. The communication apparatus may then receive the loading rate indices of the cells liable to be assigned to the communication apparatus. The communication device then may select, from among the cells liable to be assigned to the communication apparatus, the cell to which the communication apparatus is assigned, at least, as a function of the loading rate indices.
