METHOD AND APPARATUS FOR PROVIDING RANDOM ACCESS INFORMATION WHEN PAGING A WIRELESS DEVICE

摘要

The present invention relates to a method for supporting random access (RA) of a wireless device. The method is performed in a radio network node of a wireless communication system. The radio network node serves a cell. The method comprises determining (610) whether to allocate a dedicated RA preamble to the wireless device at paging of the wireless device in the cell. When it is determined to allocate the dedicated RA preamble to the wireless device at paging, the method further comprises transmitting (620) an indicator of the dedicated RA preamble to the wireless device in a message related to the paging of the wireless device. The dedicated RA preamble is valid for RA during a time window. Corresponding methods in the wireless device and in a core network node are also provided, as well as the nodes themselves.
