APPARATUSES, METHODS AND COMPUTER PROGRAMS FOR A MOBILITY MANAGEMENT UNIT OF A FIRST AND A SECOND MOBILE COMMUNICATION SYSTEM AND A MOBILE TRANSCEIVER

摘要

Embodiments provide apparatuses (10; 20; 30), methods and computer programs suitable for mobility management units (100; 200) of a first (1000) and a second (2000) mobile communication system and a mobile transceiver (300). The apparatus (10) is suitable for the mobility management unit (100) of the first mobile communication system (1000). The apparatus (10) comprises at least one input (12) to obtain information related to a cluster of base station transceivers (150) of the first mobile communication system (1000) from a mobility management unit (200) of a second mobile communication system (2000). The information related to the cluster of base station transceivers comprises information related to one or more base station transceivers of the first mobile communication system (1000). A mobile transceiver (300) is within a vicinity of a base station transceiver (250) of the second mobile communication system (2000) and within a vicinity of the one or more base station transceivers. The apparatus (10) further comprises a control module (14) to effect data buffering of payload data for the mobile transceiver (300) at the one or more base station transceivers of the cluster of base station transceivers (150) based on the information related to the cluster of base station transceivers.
