Patent number: 8358643Abstract: A communication method for reducing Radio Resource Control (RRC) connection setup time in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) includes the step of using an inclusive Signalling Radio Bearer (iSRB) in place of a plurality of individual Signalling Radio Bearers (indSRBs) for transferring signals from Radio Resource Control (RRC) to Medium Access Control (MAC). A Protocol Discriminator (PD) is added to the tail (right side) of each indSRB at the RRC for allowing the MAC to identify each indSRB as received in the iSRB. The PD is needed because the MAC would otherwise be unable to place each indSRB into the appropriate prioritizing queue for trans-mission to the physical layer. The PD is stripped off at the MAC. A preferred embodiment uses the iSRB in place of four individual indSRBs (SRB1, SRB2, SRB3 and SRB4), but in an alternative form the Unacknowledged Mode SRB (SRBI) would not be present in the system and therefore not included in the iSRB.Type: GrantFiled: February 7, 2007Date of Patent: January 22, 2013Assignee: NEC CorporationInventor: Jagdeep Singh Ahluwalia
