    • Calls are routed in a distributed mobile switching center environment in response to receiving a call to be routed from a first switching mode (310(1) to a second switching node (3101(2)). An inter-switch mute for the call from the first switching node to the second switching node is identified. The inter-switch route includes an intermediate switching node (305) having multiple media gateway (320). An intra-switch route within the intermediate switching node is selected from multiple possible intra-switch routes for use in establishing the inter-switch route. Each of the intra-switch routes includes one or more interconnections (330) between media gateways. The call is connected using the identified inter-switch route and the selected intra-switch route.
    • 响应于接收到要从第一交换模式(310(1)到第二交换节点(3101(2))路由的呼叫,在分布式移动交换中心环境中路由呼叫。 识别到第二交换节点的第一交换节点,交换机间路由包括具有多个媒体网关(320)的中间交换节点(305),中间交换节点内的交换机内路由多个可能的内部交换节点 交换路由,用于建立交换机间路由,每个交换机内路由包括媒体网关之间的一个或多个互连(330),该呼叫使用所识别的交换机间路由和所选择的交换机内路由进行连接。

    • Provided is a method and system for enabling mobile devices, radio access networks (RANs), and core networks (CNs) based on different specifications and underlying technologies to communicate. The mobile device and the RAN may be based on one technology, such as a code division multiple access (CDMA) specification, while the CN may be based on another technology, such as a global system for mobile communications (GSM) specification. The method takes a CDMA message received by the RAN, converts it into a corresponding GSM message, and passes it to the CN. Alternatively, a new GSM message may be created. Similarly, a GSM message from the CN may be converted into a CDMA message (or a new CDMA message may be created) and the CDMA message passed on to the RAN. The method may also initiate a function or procedure in one portion of a network using one technology when a certain message is received from another portion of the network using a different technology. This provides a cost-effective and flexible process that, among other advantages, enables the mobile device to communicate with incompatible CNs.
    • 提供了一种用于基于不同规格和底层技术来实现移动设备,无线电接入网络(RAN)和核心网络(CN)的通信的方法和系统。 移动设备和RAN可以基于诸如码分多址(CDMA)规范的一种技术,而CN可以基于另一种技术,例如全球移动通信系统(GSM)规范。 该方法接收由RAN接收的CDMA消息,将其转换为对应的GSM消息,并将其传递给CN。 或者,可以创建新的GSM消息。 类似地,来自CN的GSM消息可以被转换成CDMA消息(或者可以创建新的CDMA消息),并且CDMA消息传递到RAN。 当使用不同的技术从网络的另一部分接收到某个消息时,该方法还可以使用一种技术来发起网络的一部分中的功能或过程。 这提供了一种成本有效和灵活的过程,除了其他优点之外,移动设备能够与不兼容的CN通信。

    • Provided is a method and system for minimizing call setup delay in a network. The system includes a central node that may be connected to multiple home location registers (HLRs) and a number portability database (NPDB). The central node may also be associated with two tables. The first table includes mobile station identifiers and associated location routing numbers (LRNs), and the second table includes mobile station identifiers and associated home location registers (HLRs). The method searches the first and second tables for a mobile station identifier that matches a mobile station identifier associated with a call. If a match is found, the method uses the associated LRN or HLR to continue with the call setup or to obtain further information. If no match is found, the method sends a query to the NPDB. The method may also dynamically update the first and second tables as current information is obtained.
    • 提供了一种用于最小化网络中的呼叫建立延迟的方法和系统。 该系统包括可连接到多个归属位置寄存器(HLR)和数字可移植性数据库(NPDB)的中央节点。 中央节点也可以与两个表相关联。 第一表包括移动站标识符和相关联的位置路由号码(LRN),第二表包括移动站标识符和相关的归属位置寄存器(HLR)。 该方法在第一和第二表中搜索与与呼叫相关联的移动站标识符匹配的移动站标识符。 如果找到匹配项,则该方法使用关联的LRN或HLR继续呼叫建立或获取更多信息。 如果没有找到匹配项,则该方法向NPDB发送查询。 该方法还可以当获得当前信息时动态地更新第一和第二表。
