    • Network nodes for an access network and a home network of a first UE are described for use when routing an originating call from the first UE in the access network including an IMS network. A network node receives a SIP INVITE message associated with the originating call from the first UE, and including a called party number associated with the call. It determines whether the first UE is visiting the access network and whether the called party number is associated with the access network. A query to a database is performed, the database comprising a plurality of called party numbers, as to whether the called party number is allowable for use in the access network when the UE is visiting and when the called party number is associated with the access network. Instructing the home network to route the originating call to the access network when a response from the query indicates the called party number is allowable for use in the access network. The home network receives the instruction and routes the originating call to the access network for further processing.
    • 当在包括IMS网络的接入网络中路由来自第一UE的始发呼叫时,描述用于接入网络和第一UE的归属网络的网络节点。 网络节点从第一UE接收与起始呼叫相关联的SIP INVITE消息,并且包括与呼叫相关联的被叫方号码。 它确定第一UE是否正在访问接入网络以及被叫方号码是否与接入网络相关联。 执行对数据库的查询,数据库包括多个被叫方号码,关于当UE正在访问时被叫方号码是否被允许用于接入网络,以及被叫方号码是否与接入网络相关联 。 当来自查询的响应指示被叫方号码被允许在接入网络中使用时,指示家庭网络将始发呼叫路由到接入网络。 家庭网络接收指令,并将起始呼叫路由到接入网络进行进一步处理。
