The invention relates to a method of operating a base station (110) of a cellular communications network (100), wherein said base station (110) is configured to receive signaling information (si1, si2) from at least one terminal (10a) served by said base station (110) and/or from a further network element (120) of said cellular communications network (100), wherein said base station (110) determines (200) whether received signaling information (si1, si2) comprises an emergency indication which indicates an existing or impending emergency situation, and wherein said base station (110) notifies (210) at least one further terminal (10b, 10c) served by said base station (110) and/or a further network element (130) of said emergency situation.
摘要:
Data transmission between a mobile client (1) and a cellular network (4) can be performed via an ad-hoc network (2) extension of the cellular network and a mobile relay (3). To reduce the overhead induced by the ad-hoc network (2) extension and still reap the benefits of extending the cellular network (4) by the ad-hoc network (2) it is suggested that a first part of the data that are transmitted from the mobile client (1) towards the cellular network (4) are transmitted directly via the air interface (8) and a second part of the data that are transmitted from the mobile client (1) towards the cellular network (4) are transmitted via the ad-hoc network (2) and the mobile relay (3). Alternatively or additionally it is suggested that a first part of the data that are transmitted from the cellular network (4) towards the mobile client (1) are transmitted directly via the air interface (8) and a second part of the data that are transmitted from the cellular network (4) towards the mobile client (1) are transmitted via the mobile relay (3) and the ad-hoc network (2).

To reduce the overhead induced by transmitting data between a mobile client (1) and a cellular network (4) via an ad-hoc network (2) extension it is suggested, that the cellular network (4) transmits data dedicated to the mobile relay (3) and dedicated to the mobile client (1) within the same data stream; the mobile relay (3) detects whether data received by the mobile relay (3) contains data that are dedicated to the mobile relay (3) itself and terminates the part of the received data that is dedicated to the mobile relay (3) itself; the mobile relay (3) detects whether data received by the mobile relay (3) contains data that are dedicated to the mobile client (1) and forwards the part that is dedicated to the mobile client (1) to the mobile client (1); and the mobile relay (3) detects whether data received by the mobile relay (3) contains data that are dedicated to the cellular network (4) and forwards the part that is dedicated to the cellular network (4) to the cellular network (4).
