The invention refers to a method in a wireless data communication network (1) comprising a mobile first user equipment (UE1) and a broadcast server (BCS). The first user via equipment (UE1) communicates with a radio base station (RBS) via a first port (P1) on a first channel (CH1) for in- and outgoing broadcast traffic provided by a service provider (3) and communicates with the broadcast server (BCS) via a first client application (UCA1) comprised in the first user equipment. Based on information from the first client application (UCA1) and other client applications, the broadcast server (BCS) makes a decision whether to allow several user equipments to chare a common channel or not.

摘要:
A method for letting a temporary radio base station (RBS, 140) gain and maintain control of the traffic of a targeted RBS (120) in a system (100), where RBS's transmit an identity signal and a list of candidate frequencies for use by user terminals when switching RBS. The temporary RBS (140) is positioned in or adjacent to the targeted RBS (120), and transmits on a frequency in the candidate list of the targeted RBS (120). The transmissions are at such a power level that the traffic of the targeted RBS (120) is transferred to the temporary RBS (140). The temporary RBS transmits the identity signal the RBS whose frequency the temporary RBS transmits on, and transmits a list of candidate frequencies such that user terminals whose traffic has been transferred to the temporary RBS cannot find signals with sufficient strength on any of the candidate frequencies.

The invention refers to a base station (BTS) and a method for a BTS, for a cellular communication system comprising a user equipment (UE) onboard an aircraft, when at a predetermined altitude, and a terrestrial network. The invention is characterised in that the BTS is arranged to be an airborne onboard BTS comprising a screening device generating a first signal (S1) matched to screen a second signal (S2) from the terrestrial network at a predetermined altitude. The onboard BTS also comprises a signal generator generating a third signal (S3) stronger than both the first signal (S1) and the second signal (S2), the onboard BTS arranged to establish a communication link with the UE via the third signal (S3).

The present invention relates to a device (4, 5, 6, 7, 8) adapted for transmission and reception via a satellite link (2) in a satellite communication system (3). The device (4, 5, 6, 7, 8) is further a part of a group (9, 21) of similar devices (4, 5, 6, 7, 8), where the device (4, 5, 6, 7, 8) comprises a first address (14), unique for the device (4, 5, 6, 7, 8). The device (4, 5, 6, 7, 8) further comprises at least a second address (15, 19) that is common for the group (9, 21), enabling a message (22a, 22b, 22c) sent to the group (9, 21) to be addressed to the group (9, 21). This means that a single transmission is sufficient to reach all members (4, 5, 6, 7, 8) in the group (9, 21). The present invention also relates to a satellite communications system comprising devices according to the above. The present invention also relates to a method for transmission and reception via a satellite link.

The invention refers to traffic controller in a cellular radio system comprising at least one radio base station (BTS) associated with a plurality of traffic channels (T) for serving a cell (C1), and a plurality of mobile stations (MS) within the cell. The traffic controller is arranged to delicate one of the downlink traffic channels (TCHdl1) for a selected group of mobile stations (MS) and is also arranged to delicate one of the uplink traffic channels (TCHul1) for the selected group of mobile stations (MS). Each of the mobile stations (MS1-MS3) in the selected group of mobile stations comprises communication means for inter group communication via the delicated downlink channel (TCHdl1) and the delicated uplink channel (TCHul1) only.

The invention concerns a temporary radio base station, temporary RBS (140), which can gain and maintain control of the traffic to and from a targeted radio base station (120) in a wireless cellular telecommunications system (100), and a dedicated user terminal (530) for use the system. The dedicated user terminal (530) comprises an identification device being arranged to identify the temporary RBS (140) by use of unique information being at least embedded in a transmitted signal from the temporary RBS (140). The dedicated user terminal (530) is arranged to disregard the temporary RBS (140) when detected, and to choose the targeted RBS (120), or an RBS arranged to operate in a neighboring cell, in the same manner as if the temporary RBS (140) would not exist. The invention also relates to a method for the devices and a system comprising the devices.
