摘要
关于当EPC HSS和IMS HSS分离部署时eSRVCC如何实现,即eSRVCC相关的数据在EPC HSS和IMS HSS之间如何互通,3GPP未给出规范说明。通过对已有技术的分析,提出了在EPC HSS和IMS HSS之间使用扩展的MAP ATI消息或者复用Sh接口的Diameter消息,实现EPC HSS和IMS HSS之间数据互通的方案,从而在分离部署的EPC HSS和IMS HSS实现eSRVCC功能。
3GPP does not specify data access solution to eSRVCC when EPC HSS and IMS HSS are deployed separately. Based on analyses on existing techniques, a data access solution between EPC HSS and IMS HSS was proposed that the extended MAP ATI message is used or Diameter message on the Sh interface is multiplexed between EPC HSS and IMS HSS. Thus, eSRVCC functions were implemented in separated EPC HSS and IMS HSS.
