Abstract: A method for adjusting a bandwidth of a carrier signal providing access to a cellular radio network through a High Altitude Platform, HAP, the carrier signal being transmitted within a predetermined frequency spectrum channel, the HAP transmitting a first carrier signal of a first bandwidth in a first part of the predetermined frequency spectrum allocation, the method comprising: configuring transmission of a second carrier signal of a second bandwidth in a second part of the predetermined frequency spectrum allocation, the second bandwidth being different to the first bandwidth; and configuring handover of traffic from the first carrier signal to the second carrier signal.

Abstract: A method for providing an indoor location of a mobile device, the mobile device having satellite navigation capabilities so that it is capable of reporting GNSS location information, the method comprising: upon detecting that the mobile device has stopped reporting its GNSS location information determining: i) whether a signal level value obtained from the signal levels reported by the mobile device from the serving cell and neighbouring cells has decreased more than a predefined amount of decibels during a first time window since the last GNNS location information was reported; and ii) whether the last reported GNSS location information was less than a predefined distance from a building; and using the position coordinates of such building as the location of the mobile device when both conditions i) and ii) are met.

Abstract: The invention relates to a cellular communication network serving mobile terminals or devices and how to reduce the signalling load in said network by introducing an auxiliary device which holds data packets in order to minimize connections according to a pre-determined rule.
