    摘要: A method and apparatus may be used for increasing control channel capacity in Global System for Mobile communications (GSM). In a first method, the Multi-User-Reusing-One-Slot or Voice Services Over Adaptive Multiuser Channels On One Slot (MUROS/VAMOS) concept may be applied to timeslots or bursts carrying a Stand Alone Dedicated Control Channel (SDCCH). In a second method, the control signaling needed to support call setup for voice traffic may be switched over to a MUROS/VAMOS-capable traffic channel as early as possible instead of being handled through the SDCCH. In a third method, the channel coding format of the signaling bursts and/or bursts sent and received on the allocated traffic or SDCCH timeslots or resources may be modified to provide for additional link robustness and to overcome an intrinsic penalty when allowing for two simultaneous wireless transmit/receive units (WTRUs) on a timeslot used for signaling. In a fourth method, a WTRU may notify the GSM network that the WTRU is MUROS/VAMOS capable.

    摘要: Methods and apparatus for improved Multiple Users Reusing One Slot (MUROS) operation include two or more wireless transmit/receive units (WTRU) multiplexed onto multiple sub-channels in a single timeslot. Addressing information included in layer two headers, Radio Resource Control (RRC) messages, and layer one parameters in a SACCH/FACCH transmission indicate that the transmission is intended for a particular WTRU. A FACCH transmission may be sent on a sub-channel reserved for another WTRU. Stealing bits in a voice frame may be set to indicate that the FACCH transmission is intended for a WTRU on the sub-channel reserved for another WTRU. Different WTRUs in a multiplexed group may be configured to decode layer one parameters in a SAACH according to alternating patterns.

    摘要: A method for implementing a fallback procedure from a packet switched (PS) radio access technology (RAT) to a circuit switched (CS) RAT is disclosed. A paging message is received at a wireless transmit/receive unit (WTRU) via the PS RAT, the paging message including a WTRU identifier and a domain indicator, wherein the domain indicator indicates whether the paging message is related to a service on the CS RAT. If the WTRU identifier in the paging message matches a stored identifier of the receiving WTRU, then a fallback procedure to the CS RAT is performed. The WTRU responds to the paging message using a CS RAT-based identifier assigned to the WTRU.
