    • 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. If the link quality is lower than a preset value, calculate an N and delete N of data frames from the second base station when N is larger than zero. The N is equal to number of data frames not yet deleted from the second base station and already received by the mobile unit.
    • 本发明提供了一种用于无线通信网络系统中基站的帧同步的溢出控制方法。 无线通信网络系统包括无线电网络控制器,第一基站,第二基站和移动单元。 无线网络控制器向第一基站和第二基站发送多个数据帧。 本发明包括以下步骤。 首先,确定由第二基站接收到的多个数据帧的数量是否大于判断存储容量。 第二,如果数量较大,则计算X并从第二基站删除数据帧的X。 X等于从数字中减去判断存储容量的结果。 同时,检测移动单元与第一基站之间的链路质量。 如果链路质量低于预设值,当N大于零时,计算N并从第二基站删除N个数据帧。 N等于尚未从第二基站删除并且已经被移动单元接收的数据帧的数量。

    • 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.
    • 本发明提出了一种用于诸如GPRS和UMTS系统的无线数据网络的移动性管理方法和系统。 无线数据网络由至少一个移动设备和一个网络设备组成。 无线数据网络中的小区被划分成若干路由区域。 在无线数据网络中,移动设备的移动性管理活动的特征在于移动管理有限状态机在移动设备和网络设备两者中运行。 机器有三种状态:空闲状态,待机状态和就绪状态。 移动设备和网络设备都采用准备好的计数器,其计数在两个分组传输之间的分组空闲周期中由移动设备交叉的小区的数量。 如果计数数达到阈值,则移动性管理状态从就绪状态切换到待机状态。

    • A mobile communication system is disclosed including one or more home location registers, one or more visitor location registers and one or more mobile terminal equipments. Each mobile terminal equipment is served by a single home location register. Each registration area or geographical area of mobile communication service is covered or served by a visitor location register. "Overflow" mobile terminals, i.e., more mobile terminals than user records that can be maintained at the visitor location registers, are permitted to register at the visitor location registers. To that end, each home location register maintains an indication, e.g., a bit, for each mobile terminal it manages indicating whether or not the mobile terminal is an overflow mobile termninal. 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. One mobile terminal is selected as an overflow terminal and the user record for that terminal is deleted or is not generated. The home location register for the overflow mobile terminal then sets the overflow indicator for the mobile terminal to indicate that it is is the overflow terminal. Overflow mobile terminals are easily canceled--no user record is stored for such mobile terminals at the visitor location register. Calls can be originated by overflow mobile terminals by first forcing them to re-register. To terminate calls to overflow mobile terminals, the visitor location register must allocate a user record to the overflow terminal, including possibly selecting another mobile terminal as an overflow mobile terminal, thereby making a user record available.
    • 公开了包括一个或多个归属位置寄存器,一个或多个访问者位置寄存器和一个或多个移动终端设备的移动通信系统。 每个移动终端设备由单个归属位置寄存器服务。 移动通信服务的每个注册区域或地理区域由访问者位置寄存器覆盖或服务。 允许在访问者位置寄存器处注册“移动”移动终端,即比可以在访问者位置寄存器处保持的用户记录更多的移动终端。 为此,每个归属位置寄存器为其管理的每个移动终端维护一个指示,例如一位,指示移动终端是否是溢出的移动终端。 当移动终端在访问者位置寄存器处被注册并且没有用户记录可用时,访客位置记录仍然登记移动终端。 选择一个移动终端作为溢出终端,并且该终端的用户记录被删除或不被生成。 溢出移动终端的归属位置寄存器然后设置移动终端的溢出指示符,以指示它是溢出终端。 溢出移动终端容易被取消 - 在访问者位置寄存器中没有为这样的移动终端存储用户记录。 呼叫可以由移动终端溢出发起,首先强制他们重新注册。 为了终止对溢出移动终端的呼叫,访问者位置寄存器必须向溢出终端分配用户记录,包括可能选择另一个移动终端作为溢出移动终端,从而使得用户记录可用。

    • The present invention provides a system and method for accelerating call setup by caching, wherein a user equipment accesses an IMS network via a radio access network and a GPRS core network. The GPRS core network has a HSS recorded with data associated with the user equipment. The IMS network comprises at least one S-CSCF and at least one I-CSCF. The I-CSCF has a cache device. At first, the user equipment sends a register signal which is forwarded to the I-CSCF, and the I-CSCF inquiries the HSS about the services that the user equipment has applied, so as to select an S-CSCF. Then, I-CSCF forwards the register signal to the selected S-CSCF, and the S-CSCF registers to the HSS as being mapped to the user equipment. Finally, when the I-CSCF receives an OK signal, the mapping between the user equipment and the S-CSCF is recorded in the cache device.
