Abstract

An uplink beacon signal is transmitted from a terminal (UE) to a plurality of base stations (eNB A, eNB B, eNB C). For each radio path between the terminal and UE a respective measurement is obtained of a characteristic of the path, using the respect uplink beacon signals. The beacon signals are also used to determine a timing value for each path. The measured radio path characteristics and timing values are stored in a database which is common to a plurality of databases within the coverage area in which the terminal resides. For example, the database may be associated with a radio network controller (RNC). The beacon signals may be sounding reference signals (SRS) or a transmission burst in a dedicated random access channel. The characteristic of the radio path may be the received signal level. The database may be read and used when making a handover decision for the terminal.
