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

A mobile terminal is attached to a first network of a first technology type RAT1. The mobile terminal transmits UE capability information to the first network by a plurality of containers. Each container relates to one type of technology which is supported by the mobile terminal. Each container includes an indicator tag identifying the RAT to which its contents relate. On receipt of the containers, the first network decodes the content of the container that is indicated to be of its own technology type. If there is a neighbouring network of another technology type with which the mobile terminal is compatible, the first network sends the relevant container to the second network, where its content is decoded. The second network may return generalized information derived from the container back to the first network. This mechanism provides a content-agnostic approach for transferring mobile capability information between networks of different technology types.

Apparatus and method for handling mobile terminal capability information

The present invention relates to a method for controlling sleep mode in a terminal comprising at least two network interfaces. According to the present invention, the method comprises the steps of:

Method for controlling the sleep mode on a mobile terminal, corresponding mobile terminal, and corresponding radio access node

To reduce the overhead induced by transmitting data between a mobile client and a cellular network via an ad-hoc network extension, the cellular network transmits data dedicated to the mobile relay and dedicated to the mobile client within the same data stream, the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the mobile relay itself and terminates the part of the received data that is dedicated to the mobile relay itself, the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the mobile client and forwards the part that is dedicated to the mobile client to the mobile client, and the mobile relay detects whether data received by the mobile relay contains data that are dedicated to the cellular network and forwards the part that is dedicated to the cellular network to the cellular network.

Air interface protocols for a radio access network with ad-hoc extensions

Provided are a radio access network, a distributed radio network controlling structure and a network element, each providing mobile communications services, and each having controlling elements including at least one control plane server for providing control plane functions and at least one user plane server for providing user plane functions, and a network having a mapping function for interfacing the radio control elements with a core network. Using this solution, only the network element containing a mapping function interfaces with the core network.

Radio access network and network elements for providing mobile communications services

Data transmission between a mobile client () and a cellular network () can be performed via an ad-hoc network () extension of the cellular network and a mobile relay (). To reduce the overhead induced by the ad-hoc network () extension and still reap the benefits of extending the cellular network () by the ad-hoc network () it is suggested that a first part of the data that are transmitted from the mobile client () towards the cellular network () are transmitted directly via the air interface () and a second part of the data that are transmitted from the mobile client () towards the cellular network () are transmitted via the ad-hoc network () and the mobile relay (). Alternatively or additionally it is suggested that a first part of the data that are transmitted from the cellular network () towards the mobile client () are transmitted directly via the air interface () and a second part of the data that are transmitted from the cellular network () towards the mobile client () are transmitted via the mobile relay () and the ad-hoc network ().

Ad-hoc extensions of a cellular air interface

The invention relates to a method for routing a message from a Cell Control to a Mobile Control of a Radio Network Control equipment and vice versa. Such methods are substantially known in the art for Radio Network Controllers RNCs. The present invention proposes a communication between functional entities of a distributed RNC enabling the routing of the message by using known protocols and reusing identifiers already known for these protocols.
