  • Multimedia broadcast and multicast service paging
    Patent number: 7242919
    Abstract: This invention provides a paging method for Multimedia Broadcast/Multicast Service in mobile communication system. The paging process and radio resource setup process are merged in this method to try to reduce uplink responses. This invention extends existing PCH IubFP frame structure by adding MBMS Indication bit(MI) to PCH IubFP frame. The PCH IubFP frame includes Paging Indication (PI) and Paging Message. Paging message carries MBMS service information. MBMS Service Identity or MBMS Paging Indicator is added to the reserved 12 bits in Paging Indicator Channel (PICH) frame structure.
