    • In accordance with one aspect of the invention there is provided a process for handling emergency calls from a caller in a voice over IP system. The process involves receiving a routing request message including a caller identifier and a callee identifier. The process also involves setting an emergency call flag active in response to the callee identifier matching an emergency call identifier pre-associated with the caller. The process further involves producing an emergency response center identifier in response to the emergency call identifier. The process also involves determining whether the caller identifier is associated with a pre-associated direct inward dialing (DID) identifier. The process further involves producing a direct inward dialing (DID) identifier for the caller by associating a temporary DID identifier with the caller identifier when the emergency call flag is active and it is determined that the caller has no pre-associated DID. The process also involves producing a routing message including the emergency response center identifier and the temporary DID identifier for receipt by a routing controller operable to cause a route to be established between the caller and the emergency response center.
    • 根据本发明的一个方面,提供了一种用于在IP语音系统中处理来自呼叫者的紧急呼叫的过程。 该过程涉及接收包括主叫标识符和被叫标识符的路由请求消息。 该过程还包括响应于与呼叫者预先关联的紧急呼叫标识符匹配的被呼叫者标识符来设置活动的紧急呼叫标志。 该过程还涉及响应于紧急呼叫标识符产生紧急响应中心标识符。 该过程还涉及确定呼叫者标识符是否与预先关联的直接向内拨号(DID)标识符相关联。 该过程进一步包括当紧急呼叫标志是活动的并且确定呼叫者没有预先关联的DID时,通过将临时DID标识符与呼叫者标识符相关联来产生呼叫者的直接向内拨号(DID)标识符。 该过程还涉及产生路由消息,该路由消息包括紧急响应中心标识符和临时DID标识符,用于由路由控制器接收,用于使呼叫者和应急响应中心之间建立路由。

    • The present invention allows mobile terminals to initiate calls to either PSTN or non-PSTN addresses through a cellular interface. In operation, the mobile terminal will determine a terminating address to which a call is to be initiated based on user input or selection. The mobile terminal will then determine whether the terminating address should be used to directly initiate a call through the cellular interface. When the terminating address should be used to directly initiate the call, the mobile terminal will directly initiate the call using the terminating address. When the terminating address should not be used to directly initiate the call, the mobile terminal will send the terminating address to a service node. The service node will then initiate an indirect call process using the terminating address to establish the call between an endpoint associated with the terminating address and the cellular interface of the mobile terminal.
    • 本发明允许移动终端通过蜂窝接口向PSTN或非PSTN地址发起呼叫。 在操作中,移动终端将基于用户输入或选择来确定呼叫将被启动到的终止地址。 然后,移动终端将确定终端地址是否应该被用来通过蜂窝接口直接发起呼叫。 当应使用终端地址直接发起呼叫时,移动终端将使用终止地址直接发起呼叫。 当不应使用终止地址来直接发起呼叫时,移动终端将把终止地址发送到服务节点。 然后,服务节点将使用终止地址发起间接呼叫过程,以建立与终止地址相关联的端点与移动终端的蜂窝接口之间的呼叫。
