A method () to generate test suite for a source-code (). The method comprises: a) implementing a structural analysis () of said source-code () to obtain a completed source-code () including: &#x2014;parsing the source-code, &#x2014;addition of annotations defining tests objectives, &#x2014;generation of stubs; b) implementing at least one semantic analysis algorithm including categorizing each set of tests objectives as satisfied, impossible to satisfy or unsatisfied; c) feeding a first list () with satisfied test cases; d) feeding a second list () with test objectives impossible to satisfy, e) implementing at least one mathematical optimization algorithm () on parts corresponding to unsatisfied test objectives; &#x2014;identifying test cases () that satisfy at least a part of said test objectives, &#x2014;feeding said first list of set of test cases with them, &#x2014;categorizing said test objectives as satisfied; f) providing a test suite comprising the two lists.

Method to generate test suite for source-code

The present invention concerns a method for enabling a first base station to be included within a wireless cellular network, the wireless cellular network comprising a server, a plurality of second base stations and a telecommunication network linking the base stations and the server, the base stations managing cells. The first base station transfers a first message comprising at least an identifier of the first base station and information representative of the location of the first base station to the server, receives from the server a second message comprising an identifier of a second base station which manages a cell which is neighbor of a cell of the first base station and a certificate proving that the first base station is authorized to communicate with the second base station, transfers to the second base station a third message comprising the certificate in order to establish a communication with the second base station.

Method for enabling a base station to connect to a wireless telecommunication network

The present invention concerns a first base station managing a neighboring condition and cell area operation of a cell area, the cell area being a cell area of a wireless cellular network, the wireless cellular network comprising a telecommunication network enabling a transfer of information between the first base station and a second base station, where the wireless cellular network comprises a server linked to the telecommunication network.

The present invention concerns a method for determining if a first cell managed by a first base station is neighbour of a second cell managed by a second base station, the cells being cells of wireless cellular network, the wireless cellular network comprising a telecommunication network enabling the transfer of information between the base stations. The first base station monitors the amount of information transferred between the first base station and the second base station through the telecommunication network and determines if the second cell managed by the second base station is neighbour of the first cell managed by the first base station according to the amount of monitored information transferred between the first base station and the second base station through the telecommunication network. The invention concerns also the associated device.

Method for determining if a first cell managed by a first base station is neighbour of a second cell managed by a second base station

The present invention concerns a method for determining neighboring condition and cell area operation of a cell area managed by a base station, the cell area being a cell area of a wireless cellular network, the wireless cellular network comprising a telecommunication network enabling the transfer of information between a first base station and a second base station, wherein the wireless cellular network comprises a server linked to the telecommunication network. The first base station configures an operation domain of a first cell area managed by the first base station based on the information representative of the operation domain of the second cell area received from the second base station via the direct connection. The invention concerns also the associated non-transitory computer readable storage medium including stored thereon a computer program for implementing a method for determining cell area operation of a cell area managed by a base station.

The present invention concerns a method for determining a location area of a mobile terminal in a wireless cellular telecommunication network, the mobile terminal being located in a first wireless area of the wireless cellular telecommunication network. The method comprises the steps, executed by a telecommunication device of the wireless cellular telecommunication network, of:

Methods and devices for determining a location area of a wireless cellular telecommunication network

A Passive Optical Network (PON) comprises at least a first sub-network () with a first Optical Line Terminal () and a first set of Optical Network Units (), a second sub-network () with a second Optical Line Terminal () and a second set of Optical Network Units () interconnected to a same splitter (). In downlink direction from Optical Line Terminals to Optical Network Units, each sub-network uses a different wavelength (&#x3bb;) and in uplink direction all ONUs () are able to access all Optical Line Terminals through an uplink TDMA access by using one single wavelength (&#x3bb;). The dynamic transmission resources allocation units of all Optical Line Terminals have the same process and coordination of the uplink TDMA access is carried out by sending () from a determined master Optical Network Unit to the other Optical Line Terminals different from its associated Optical Line Terminal an echoed synchronization message containing synchronization information related to its corresponding Optical Line Terminal referred as master Optical Line Terminal.
