    • Methods and apparatus for use in processing Session Initiation Protocol (SIP) calls in a network environment which includes a circuit-switched (CS) network and an Internet Protocol (IP) multimedia subsystem (IMS) network. In one illustrative technique, a SIP Register message is sent from a mobile communication device to the IMS network for registration of the mobile device. A SIP 200 OK message is received by the mobile device from the IMS network in response to sending the SIP Register message. The SIP 200 OK message has one or more variable call parameters or a network address at which to obtain the variable call parameters. The variable call parameters may include an E.164 number which may be dynamically assigned to the mobile device by the IMS network, and/or a time or timer value which defines a time period for which the E.164 number remains assigned to the mobile device. Other information may be included such as preferred access network/technology information. The variable call parameters are stored in memory of the mobile device and utilized for processing each one of a plurality of SIP calls involving the mobile device. After registration, the mobile device may initialize a timer with the timer value, run the timer and, when processing a SIP call, cause a CS call setup message which includes the E.164 number to be sent to the IMS network for routing of the call if the timer has not yet expired. If the timer has expired, the mobile device may refrain from utilizing the deassigned E.164 number in the CS call setup message and alternatively obtain and utilize a new E.164 number or an altogether different technique for processing of the SIP call. Alternative techniques for obtaining parameters and formatting the data are also described.
    • 在包括电路交换(CS)网络和互联网协议(IP)多媒体子系统(IMS)网络的网络环境中用于处理会话发起协议(SIP)呼叫的方法和装置。 在一种说明性技术中,SIP移动通信设备向IMS网络发送SIP注册消息,用于注册移动设备。 响应于发送SIP注册消息,移动设备从IMS网络接收SIP 200 OK消息。 SIP 200 OK消息具有一个或多个变量调用参数或用于获取变量调用参数的网络地址。 可变呼叫参数可以包括可以由IMS网络动态地分配给移动设备的E.164号码和/或定义将E.164号码分配给移动台的时间段的时间或定时器值 设备。 可以包括诸如首选接入网络/技术信息的其他信息。 可变呼叫参数存储在移动设备的存储器中,并用于处理涉及移动设备的多个SIP呼叫中的每一个。 注册后,移动设备可以使用定时器值初始化定时器,运行定时器,并且在处理SIP呼叫时,将包含E.164号码的CS呼叫建立消息发送到IMS网络,用于路由 如果定时器尚未过期,则调用。 如果定时器已经到期,则移动设备可以避免在CS呼叫建立消息中使用解除分配的E.164号码,并且可替代地获得并利用新的E.164号码或完全不同的技术来处理SIP呼叫。 还描述了用于获取参数和格式化数据的替代技术。
