<p>Techniques for selectively steering traffic over E-DCH or over PRACH in a UMTS network are disclosed. An example method, implemented in a base station, includes the receiving (62, 72) of configuration data from a controlling node, such as a UTRAN RNC, the configuration data including parameters that define a condition for triggering a change in random access mode. The configuration data may include one or more resource-related thresholds and time-to-trigger values. The base station monitors (64, 74) one or more resource-related conditions and detects an event for triggering a change in random access mode. In some embodiments, the base station sends (66) a trigger message to the controlling network node, in response to said detecting, the trigger message indicating that a change in random access mode is needed. In other embodiments, the base station executes (76) a change in random access mode, in response to said detecting.</p> |
