Abstract: Provided is a low capability device (UE) active in a communication system comprising a plurality of satellites (Si, Sj) insuring a temporally continuous communication coverage for the low capability device (UE), said satellites being further grouped in families (S1x), satellites of a same family (S1x) sharing same and common access information, said device (UE) comprises a power saving module to send to the serving satellite (S11), during a first data session, a next access request for a next or continued data session with time indications including at least a desired next time interval to be granted for communication. Other embodiments disclosed.

Abstract: A method for using a femtocell base station and a user equipment in a public land mobile network includes: initiating a location update signalling procedure between the femtocell base station and the user equipment, wherein at least one previous location information of the user equipment is transmitted from the user equipment to the femtocell base station, the at least one previous location information being derived from or being a part of an indication regarding a last successfully visited location of the user equipment; determining whether the at least one previous location information matches at least one permission information; and continuing the location update signalling procedure in response to determining that the at least one previous location information matches the at least one permission information.

Abstract: The invention relates to a method for the allocation and release of channels in a communication system. A first session is established associated with the first mobile node via a radio node and a call control node to a conversation state. The establishment of a second session associated with a second mobile node is started in the same cell. The lack of available channels in the cell is determined in association with the second session. The first session is selected for dropping based on information on the session within the cell. The first session is released in response to the selection. Thereupon, the channel thus made available is allocated for the second session in the radio node.
