Abstract: A method and an arrangement for avoiding collision between first access attempts of at least two mobile stations being paged in a cell of a mobile communication network, wherein a paging message in a downlink channel comprises a pre-determined access order for the mobile stations being paged, whereby a first access attempt in a pre-determined TDMA frame in an uplink channel according to said access order is sent from the mobile stations being paged.

Abstract: In a system and method of adapting an ECSD connection, interruption times and data loss due to a change in the modulation, coding scheme, and number of timeslots of the connection may be minimized or eliminated. The interruption times and data loss may be minimized or eliminated by allocating a peak number of substreams for a given mobile radio connection based on a user requested data rate and/or the number of timeslots used to realize the user requested data rate. Data loss may also be minimized or eliminated by using in-band signaling to signal a change in the modulation, coding scheme, and/or number of timeslots.

Abstract: In a radio network which employs adaptive antennas for transmission of data to mobiles methods and apparatus are provided for improving the reception of transmitted data. When a block is to be transmitted in a first beam of the antenna and the block contains information for the mobile in the second beam, a modulation and coding scheme is used for the transmission of the block such that the modulation and coding scheme provides greater protection to the portion of the block containing information for the mobile in the second beam. The use of greater protection for the portion of the block which includes information for the mobile in the second beam increases the probability that the mobile in the second beam can receive and correctly decode the information intended for the mobile in the second beam in the block.

Abstract: In a base station for use in a mobile communication system for communication with mobile subscribers over a plurality of radio channels, an improved transceiver unit is provided including a traffic controller handling downlink and uplink communication traffic with mobile subscribers over the plurality of radio channels, and a measuring device measuring arrival times of burst signals from a mobile subscriber communicating on a select one of the radio channels, or from a mobile subscriber communicating on another transceiver unit, on one of the plurality of radio channels.
