Base Station, Method, Computer Program and Computer Program Product for Improved Random Access

A method implemented by a base station for improved random access, wherein said base station comprises a radio unit, wherein said radio unit comprises a transceiver and an antenna, and wherein said method comprises:

• receiving random access preamble messages from corresponding mobile communication terminals on a random access channel, each random access preamble message comprising a respective preamble;
• for each random access preamble message, determining whether the corresponding mobile communication terminal is farther away from the radio unit than an outer threshold distance;
• and
• if more than a threshold number of mobile communication terminals are farther away than the outer threshold distance, increasing the outer threshold distance and a random access cell radius of the radio unit.

A computer program product stored on a computer readable medium and comprising computer program code that, when run executed by a base station, improves random access to that base station, wherein the base station comprises a radio unit, wherein the radio unit comprises a transceiver and an antenna, and wherein the computer program code causes the base station to:

• receive random access preamble messages from corresponding mobile communication terminals on a random access channel, each random access preamble message comprising a respective preamble;
• for each random access preamble message, determine whether the corresponding mobile communication terminal is farther away from the radio unit than an outer threshold distance;
• and
• if more than a threshold number of mobile communication terminals are farther away than the outer threshold distance, increase the outer threshold distance and a random access cell radius of the radio unit.
