Patent number: 7328013Abstract: The invention concerns signalling methods in cellular telecommunication systems, especially in so called third generation cellular systems, such as the UMTS system. In the inventive method the network checks, if the mobile station is in or is about to enter into such a state, in which the mobile station needs a c-RNTI, and if that is the case, the c-RNTI is indicated to the mobile station. Preferably, the indication is effected by attaching the c-RNTI identifier to a message, which causes the change of the mobile station to the state, in which the mobile station needs the c-RNTI identifier.Type: GrantFiled: April 12, 2005Date of Patent: February 5, 2008Assignee: Nokia CorporationInventors: Jukka Vialen, Fabio Longoni
