Abstract: A multicast management mechanism for mobile networks. The mechanism proposes a multicast table approach to considerably reduce the number of short messages and multimedia messages sent to a service area, thereby reducing its paging cost. The multicast management mechanism for mobile networks includes the steps: establishing a VLR recorder table in a home location register (HLR), to record VLR addresses located by multicast users and the total number of multicast users in each VLR; and establishing LA tables, to record LA addresses in each VLR and the total number of multicast users in each LA.

Abstract: This invention proposes a mobility management method and system for wireless data networks, such as GPRS and UMTS systems. The wireless data network consists of at least one mobile device and one network apparatus. The cells in a wireless data network are partitioned into several routing areas. In the wireless data network, the mobility management activities for a mobile device are characterized by a mobility management finite state machine exercised in both the mobile device and network apparatus. There are three states in the machine: idle state, standby state and ready state. Both the mobile device and network apparatus employ a ready counter, which counts the number of cells crossed by the mobile device in the packet idle period between two packet transmissions. If the counted number reaches a threshold, the mobility management state switches from the ready state to standby state.

Abstract: The present invention provides an overflow control method for frame synchronization of base stations in wireless communication network system. The wireless communication network system includes a radio network controller, a first base station, a second base station, and a mobile unit. The radio network controller transmits a plurality of data frames to the first base station and the second base station. The present invention includes the following steps. First, determine whether number of the plurality of data frames received by the second base station is larger than a judging storage capacity. Second, calculate an X and delete X of data frames from the second base station if the number is larger. The X is equal to the result of subtracting the judging storage capacity from the number. Meanwhile, detect a link quality between the mobile unit and the first base station.

Abstract: Disclosed is a system and method for channel allocation in a multi-band wireless network. The system includes microcell base stations, at least one macrocell base station, a mobile station, and a channel allocation center. When the mobile station makes/receives a call or executes a handover, the channel allocation center uses repacking on demand (RoD) scheme to allocate a radio channel of either a macrocell base station or a microcell base station to the mobile station. RoD has the following steps. First, a microcell channel is trying to be allocated if available. If no microcell channel is available, a macrocell channel is then trying to be allocated. Third, if no macrocell channel is available, repacking is performed to execute a handover of another mobile station's call from the macrocell to another microcell, and to allocate a reclaimed macrocell channel to the mobile station. Otherwise, no repacking call is available and the mobile station is blocked or forced terminated.

When a mobile terminal is registered at the visitor location register and no user records are available, the visitor location record nevertheless registers the mobile terminal.
