    • The invention relates to implementing a method for a handover between mobile switching centers (MSC-A, MSC-B) of a cellular mobile network in high-speed data transmission wherein several channels are allocated to a mobile station (MS). In the method, the first mobile switching center (MSC-A) indicates to the second mobile switching center (MSC-B) at least the minimum number of channels required over the connection. The second mobile switching center (MSC-B) attempts to allocate at least the indicated minimum number of channels. The second mobile switching center (MSC-B) transmits to the first mobile switching center (MSC-A) data about the channels it has allocated and at least one handover number (HON). The first mobile switching center (MSC-A) may use the same handover number (HON) to perform a handover to each subchannel. According to a preferred embodiment of the invention, as many handover numbers (HON) are allocated directly as there are channels allocated to the connection.
    • 本发明涉及在高速数据传输中实现蜂窝移动网络的移动交换中心(MSC-A,MSC-B)之间切换的方法,其中将几个信道分配给移动站(MS)。 在该方法中,第一移动交换中心(MSC-A)向第二移动交换中心(MSC-B)指示至少连接所需的最小信道数。 第二移动交换中心(MSC-B)尝试至少分配所指示的最小数量的信道。 第二移动交换中心(MSC-B)向第一移动交换中心(MSC-A)发送关于其已经分配的信道和至少一个切换号码(HON)的数据。 第一移动交换中心(MSC-A)可以使用相同的切换号码(HON)来执行到每个子信道的切换。 根据本发明的优选实施例,由于存在分配给该连接的信道,所以直接分配了多个切换号码(HON)。

    • A problem arises when the data of the visitor location register (VLR) are lost for some reason. In this case, only the visitor location register (VLRn) in whose area the mobile station (MS) is located is known. The mobile station (MS) must then be paged in all location areas (LAn) of the visitor location register (VLR). Such paging of mobile stations causes a significant overload. The overload is reduced, according to the invention, by dividing the area covered by a physical visitor location area (VLR) into areas of a plurality of logical visitor location registers (LVLRn). In connection with location updatings, not only the physical visitor location register (VLR) is stored but also information on the logical visitor location register (LVLRn) in whose area the mobile station (MS) is located; in a problematic situation where the switching centre (MSC) is not aware of the location area of the mobile station (MS), the mobile station (MS) is paged, at least at first, only in the area of the logical visitor location register (LVLRn).
    • 当访客位置寄存器(VLR)的数据由于某些原因丢失时,会出现问题。 在这种情况下,只有移动台(MS)所处的访问位置寄存器(VLRn)是已知的。 然后必须在访问者位置寄存器(VLR)的所有位置区域(LAn)中寻呼移动站(MS)。 移动台的这种寻呼导致显着的过载。 根据本发明,通过将由物理访问者位置区域(VLR)覆盖的区域划分成多个逻辑访问者位置寄存器(LVLRn)的区域来减少过载。 关于位置更新,不仅存储物理访问者位置寄存器(VLR),而且存储关于移动站(MS)所在的区域中的逻辑访问者位置寄存器(LVLRn)的信息; 在交换中心(MSC)不知道移动台(MS)的位置区域的问题的情况下,至少首先仅在逻辑访问者位置寄存器的区域中寻呼移动台(MS) (LVLRn)。
