Method and device for allocating resources in a radio communication system providing resources for uplink transmission and/or for downlink transmission for a plurality of operators providing a service to a user equipment via the radio communication system, wherein the device includes a processor, memory and a transceiver, the processor being adapted to select a time division duplex configuration having an allocation of uplink transmission time and/or an allocation of downlink transmission time based on information regarding a sharing characteristic for the radio resources defined by a service level agreement between operators sharing the radio resources.

Method and device for allocating radio resources in a radio communication system

Embodiments provide apparatuses, methods and computer programs for mobile communication systems comprising base station and mobile transceivers. An apparatus for a base station transceiver (and/or a mobile transceiver) of a mobile communication system, comprises a transceiver module to communicate with the mobile transceiver (and/or base station transceiver) using first and second communication channels, wherein the first channel is more reliable than the second channel. The apparatus further comprises a controller module to control the transceiver module, and to provide a data service to the mobile transceiver (and/or base station transceiver). The data service comprises first and second data packets, wherein the first data packets comprise information related to core data of the data service, and wherein the second data packets comprise information related to optional refinement data for the data service. The first data packets use the first channel, and the second data packets use the second channel.

Apparatuses, methods and computer programs for a mobile communication system comprising a base station transceiver and a mobile transceiver

A method of wireless data transmission at a first radio access point, including detecting a degradation of a first radio link established for a first frequency band between the first radio access point and a user equipment, and sending, addressed to a network entity, information to trigger a handover or handover decision of the wireless data transmission from the first radio link of the first radio access point operating in the first frequency band to a second radio link of a second radio access point operating in the first frequency band depending on the result of the detection.

Handover method for wireless data transmission system

The invention relates to a terminal () for a cellular communications network (). The terminal is configured to maintain a first set (S) of at least n radio cells, wherein n is equal to or greater than three, wherein a quality measure (q) value of each of the n radio cells, which depends on a received signal power associated with reference signals transmitted in said cells and received by said terminal (), exceeds a threshold. The terminal further determines whether a quality measure value of a further radio cell, which is not comprised in the first set, exceeds the quality measure value of the radio cell comprised in the first set with the m-th best quality measure value, m ranging from 1 to n&#x2212;1, by a predetermined amount. If the quality measure value of the further radio cell (c) exceeds the quality measure value of the m-th best radio cell, modification of the first set is arranged, whereby a second set (S) is obtained. The second set comprises the further radio cell.

A computer implemented method of operating a base station of a wireless communication network, wherein the method comprises:

Method for detecting pci collisions

The invention relates to a telecommunication method in a base station of a mobile communication system, the mobile communication system comprising a plurality of base stations, a communication link being established between the base station and a user equipment, the method comprising the following steps performed by the base station: selecting one of the plurality of base stations as a target base station for a handover of the user equipment; transmitting a handover request to the target base station; receiving a handover request acknowledgement from the target base station, the handover request acknowledgment being indicative of at least one physical resource of the target base station; and transmitting a handover command to the user equipment via the communication link using the at least one physical resource. The handover command being descriptive of information required for accessing the target base station.

Telecommunication method and apparatus thereof

A computer implemented method of operating a base station of a wireless communication network, wherein the method comprises: comparing a number of missing context release messages () with a first criterion; &#x2014;comparing the error rate of connection reestablishment messages () with a second criterion; executing a cell global identity search algorithm () if at least one of the first and the second criterion is fulfilled, wherein the cell global identity of at least one cell with the physical cell identity of the cell where the criterion was fulfilled is requested via an automatic neighbor relation measurement, and wherein a conflict of physical cell identities is detected and reported to an information algorithm () when for the physical cell identity at least two cell global identities are found; &#x2014;an information algorithm for informing a central network element () and/or at least one base station () of the mobile communication network about a conflict of physical cell identities when a conflict of physical cell identities is reported to the information algorithm; and &#x2014;initiating a reassignment of at least one physical cell identity.

Method for detecting PCI collisions

The invention relates to methods of using a trainable software module used in the handover procedure employing the location based information for the self optimization of wireless communication networks, in particular for the self optimization of cellular mobile networks. Embodiments of the invention address the problems of radio link failures and rapid handovers immediately after transferring a wireless appliance from one base station apparatus to the other at certain cell border locations by evaluating which base station apparatus a wireless appliance should have its wireless connection transferred to using either a database or a trainable software module.
