Method of providing communication over a mobile communication network

摘要

The present invention concerns a method of providing communication over a mobile communication network (1) and components for providing communication over the communication network (1). The network (1) includes two or more fixed nodes (2a, 2b) each operating a fixed radio cell (3a, 3b) for serving one or more user equipments (4) via a first radio interface (5a, 5b). Each of these fixed radio cells (3a, 3b) is identified by a physical cell ID (6a, 6b) selected out of a set of N physical cell IDs. In addition, the network (1) includes one or more mobile relay nodes (7) served by the one or more fixed nodes (2a, 2b) via a second radio interface (8a, 8b). The mobile relay nodes (7) each operate a mobile radio cell (9) for serving one or more user equipments (4) via a third radio interface (10). Each of these mobile radio cells (9) is identified by a physical cell ID (6c) selected out of the set of N physical cell IDs. The method includes the step of dynamically assigning a physical cell ID (6c) of the set of N physical cell IDs to the one or more mobile radio cells (9).

1. A method of providing communication over a mobile communication network comprising two or more fixed nodes each operating a fixed radio cell for serving one or more user equipments via a first radio interface, wherein each of the fixed radio cells is identified by a physical cell ID, selected out of a set of N physical cell IDs, and one or more mobile relay nodes served by the two or more fixed nodes via a second radio interface, the one or more mobile relay nodes each operating a mobile radio cell for serving one or more user equipments via a third radio interface, wherein each of the mobile radio cells is identified by a physical cell ID selected out of the set of N physical cell IDs, wherein the method comprises:
dynamically assigning a physical cell ID of the set of N physical cell IDs to the one or more mobile radio cells, measuring a signal strength of a serving fixed radio cell and a signal strength of surrounding fixed radio cells by a mobile relay node, if the signal strength of a surrounding fixed radio cell exceeds the signal strength of the serving fixed radio cell, sending a handover request to the serving fixed node by the mobile relay node and executing a handover acceptance procedure between the serving fixed node and a target fixed node, and if the handover is accepted, then assigning a new physical cell ID of the set of N physical cell IDs to a mobile radio cell operated by the mobile relay node.
