A cellular mobile data packet communication system (10) comprising a first base radio station (BS1) with a first maximum number of channels which each can communicate with a first maximum number of users. The first base radio station (BS1) covers a cell (30) in the system, in which system the first base radio station indicates permission for users to communicate with it by transmitting a flag in the cell. The system is characterized in that the data communication system (10) can be expanded by adding at least a second base radio station (BS2) with a second maximum number of channels with a second maximum number of users to the first base radio station to form a base group (BG). The system additionally comprising means for deciding which base radio station has the least load, with the base radio station with the least load transmitting its permission flag.
A cellular mobile data packet communication system (10) comprising a first base radio station (BS1) with a first maximum number of channels which each can communicate with a first maximum number of users, said first base radio station (BS1) covering a cell (30) in the system, in which system the first base radio station indicates permission for users to communicate with it by transmitting a flag in the cell, characterized i n, that the data communication system (10) can be expanded by adding at least a second base radio station (BS2) with a second maximum number of channels with a second maximum number of users to the first base radio station to form a base group (BG), the system additionally comprising means for deciding which base radio station has the least load, with the base radio station with the least load transmitting its permission flag in the cell.
A system according to any of the preceding claims characterized in, that the opening of the second base radio station (BS2) can be done via an external data communication link.
A system according to any of the preceding claims characterized in, that it further comprises a third base radio station (BS3) that communicates with each of the other base radio stations (BS1, BS2) in order to even out the traffic load over the base radio stations (BS1, BS2, BS3).
A system according to any of the preceding claims characterized in, that the inter-communication system has means for deciding which base radio station (BS1, BS2, BS3) that shall set its flag.
A system according to any of the preceding claims characterized in, that the maximum number of channels in the first base radio station (BS1) is equal to one.
A system according to any of the preceding claims characterized in, that the maximum number of channels in the second base radio station (BS2) is equal to one.
A system according to any of the preceding claims characterized in, that the maximum number of channels in the third base radio station (BS3) is equal to one.
A system according to any of the preceding claims characterized in, that the base radio stations (BS1, BS2, BS3) uses the same antenna (20).
A method for use in a cellular mobile data packet communication system (10) comprising a first base radio station (BS1) with a first maximum number of channels which each can communicate with a first maximum number of users (USR), said first base radio station (BS1) covering a cell (30), in which system the first base station (BSI) indicates permission for users (USR) to communicate with it by transmitting a flag in the cell (30), which method comprises the following steps:
