步骤 412、 被叫方 MGC向被叫方 MGW返回所述主叫方 IPv4地址； 步骤 407、 408、 409与步骤 410、 411、 412的执行没有先后顺序。 Step 412: The called party MGC returns the calling party IPv4 address to the called party MGW; the steps 407, 408, 409 and the steps 410, 411, and 412 are performed in no order.
至此， 主叫方 MGW获知了当前呼叫的被叫方 IPv6地址， 被叫方 MGW获知了 当前呼叫的主叫方 IPv4地址， 同时通过地址分配设备进行附带协议转换的网络地址 转换 （Network Address Translation-Protocol Translation, 简称 NAT-PT), 从而使得呼 叫得以建立。 At this point, the calling party MGW knows the called party's IPv6 address of the current call, the called party MGW knows the calling party's IPv4 address of the current call, and performs network address translation with the protocol conversion by the address allocation device (Network Address Translation- Protocol Translation, abbreviated as NAT-PT), so that the call can be established.
本实施例中， 被叫方 MGC根据获取的来自被叫方 MGW的指示信息， 该指示信 息用以指示被叫方 MGW无法匹配出与主叫方 MGW分配的主叫方地址的版本类型对 应的被叫方地址， 能够指示地址分配设备分配另一个版本的主叫方地址和被叫方地 址，从而使得被叫方 MGW能够匹配出与地址分配设备分配的另一个版本的主叫方地 址的版本类型对应的被叫方地址，以及使得主叫方 MGW能够匹配出与地址分配设备 分配的另一个版本的被叫方地址的版本类型对应的主叫方地址，解决了现有技术中由 于主叫方 MGW和被叫方 MGW所分配的 IP地址是两个不同的版本所导致的呼叫失 败的问题， 从而保证了呼叫的正常进行。 In this embodiment, the called party MGC is configured to indicate that the called party MGW cannot match the version type of the calling party address allocated by the calling party MGW according to the obtained indication information from the called party MGW. The called party address, which can instruct the address assigning device to allocate another version of the calling party address and the called party address, so that the called party MGW can match the version of the calling party address of another version allocated with the address assigning device. The called party address corresponding to the type, and the calling party address that enables the calling party MGW to match the version type of the called party address of another version allocated by the address assigning device, solving the prior art due to the calling party The IP address assigned by the party MGW and the called party MGW is a problem of call failure caused by two different versions, thereby ensuring the normal progress of the call.

图 5为本发明实施例五提供的一种 IP地址分配的控制装置的结构示意图， 如图 5所示， 本实施例的 IP地址分配的控制装置可以包括接收模块 51和指示模块 52。其 中，接收模块 51获取来自本端 MGW的指示信息，所述指示信息用于指示本端 MGW 无法匹配出与获取的对端 MGW分配的对端第一 IP地址的版本类型对应的本端第一 IP地址，指示模块 52通过对端 MGC指示对端 MGW为本次呼叫分配对端第二 IP地 址， 以使本端 MGW匹配出与对端第二 IP地址的版本类型对应的所述本端 MGW分 配的本端第二 IP地址。FIG. 5 is a schematic structural diagram of a device for controlling IP address allocation according to Embodiment 5 of the present invention. As shown in FIG. 5, the control device for IP address allocation in this embodiment may include a receiving module 51 and an indication module 52. The receiving module 51 obtains the indication information from the local MGW, where the indication information is used to indicate the local MGW. The first IP address of the local end corresponding to the version type of the first IP address of the peer end allocated by the peer MGW is not matched, and the instructing module 52 instructs the peer MGW to allocate the second IP address of the peer to the call. The address is such that the local MGW matches the local second IP address allocated by the local MGW corresponding to the version type of the second IP address of the peer.
所述实施例一中本端 MGC、 实施例二中被叫方 MGC的功能均可以由本发明实 施例提供的 IP地址分配的控制装置实现。 The functions of the local MGC in the first embodiment and the called party MGC in the second embodiment can be implemented by the control device for IP address allocation provided by the embodiment of the present invention.
本实施例中，指示模块根据接收模块获取的来自本端 MGW的指示信息，该指示 信息用于指示本端 MGW无法匹配出与获取的对端 MGW分配的对端第一 IP地址的 版本类型对应的本端第一 IP地址， 能够通过对端 MGC指示对端 MGW为本次呼叫 分配对端第二 IP地址，从而使得本端 MGW能够匹配出与对端第二 IP地址的版本类 型对应的所述本端 MGW分配的本端第二 IP地址，解决了现有技术中由于本端 MGW 和对端 MGW所分配的 IP地址是两个不同的版本所导致的呼叫失败的问题， 从而保 证了呼叫的正常进行。 In this embodiment, the indication module is configured to use the indication information from the local MGW that is obtained by the receiving module, and the indication information is used to indicate that the local MGW cannot match the version type of the first IP address of the peer end allocated by the obtained peer MGW. The local first IP address can be used by the peer MGC to instruct the peer MGW to allocate the second IP address of the peer to the call, so that the local MGW can match the version corresponding to the version type of the second IP address of the peer. The local second IP address allocated by the local MGW solves the problem that the call failure occurs in the prior art because the IP addresses allocated by the local MGW and the opposite MGW are two different versions, thereby ensuring the call. The normal progress.
