背景技术
第三代合作伙伴计划(3GPP)已经引入了新的网络能力和新类型的设备(例如,虚拟现实(VR)设备、增强现实(AR)设备、扩展现实(XR)设备、或者机器人等)。这可以给IP多媒体系统(IP Multimedia Subsystem,IMS)多媒体电话服务带来有希望的改进。虽然企业客户认为多媒体电话服务为他们的业务提供了有吸引力的功能,但他们也遇到了一些实际问题,需要第五代移动通信技术(5G)系统的支持。5G系统有望支持增强型IMS多媒体电话服务的高级功能和性能,以满足消费者、企业客户和垂直市场的新需求。

步骤S71:接收第二UE的CSCF发送的第二邀请请求,其中,第二邀请请求,所述第二邀请请求是对第一邀请请求签名获得;其中,第二邀请请求包括第一UE的第一标识信息和第二UE的第二标识信息。
本公开实施例提供一种IMS会话方法,由第二应用服务器执行,包括:向第二网元发送第二请求,其中,第二请求包括第一UE的第一标识信息和/或第二UE的第二标识信息;第二请求用于请求证书信息。
在本公开的一些实施例中,CSCF、第二应用服务器、第二网元分别可以为上述实施例中的CSCF、第二应用服务器、第二网元;第二邀请请求可以为上述实施例中第二邀请请求;第一UE的第一标识信息、第二UE的第二标识信息分别可以为上述实施例中第一UE的第一标识信息、第二UE的第二标识信息。
示例性的,第二应用服务器可以是STI-VS或者可实现验证签名的逻辑节点或者功能。
示例性的,第二网元可以是第三方AAA服务器或者STI-CR或者其它逻辑节点或者功能。

示例性的,第三邀请请求与第一邀请请求不同。例如,第三邀请请求包括:签名信息及第一邀请请求。又如,第三邀请请求包括:第一邀请请求及验证结果;该验证结果指示验证通过。
示例性的,STI-VS获取证书信息,并基于该证书信息对第二邀请请求进行验证签名;若验证成功,则获得第三邀请请求且确定验证成功的验证结果;若验证失败,则确定验证失败的验证结果。
如此,第二应用服务器可以对第二邀请请求进行验证签名,以获得验证成功的第三邀请请求;如此可以验证出准确的用于请求第一UE发起和/或接收第二UE的IMS会话的邀请请求,有利于第一UE与第二UE安全地接入IMS网络进行IMS会话。
