3GPP在规范增强SRVCC、业务终呼域选择SDS、终呼接入域选择（T-ADS）等VoLTE相关解决方案时，都是将IMS HSS、HLR/EPC HSS作为统一的广义HSS来描述流程的，该广义HSS具备所有域的归属服务器功能。而在运营商实际部署中，HLR/EPC HSS和IMS HSS往往是分开的，此时若没有HLR/EPC HSS和IMS HSS之间的交互，这几种业务是无法开展的。针对这种场景，给出了增强SRVCC、SDS、T-ADS流程中HLR/EPC HSS和IMS HSS之间交互的方法，使得上述VoLTE相关业务可以开展。
3GPP在規範增彊SRVCC、業務終呼域選擇SDS、終呼接入域選擇（T-ADS）等VoLTE相關解決方案時，都是將IMS HSS、HLR/EPC HSS作為統一的廣義HSS來描述流程的，該廣義HSS具備所有域的歸屬服務器功能。而在運營商實際部署中，HLR/EPC HSS和IMS HSS往往是分開的，此時若沒有HLR/EPC HSS和IMS HSS之間的交互，這幾種業務是無法開展的。針對這種場景，給齣瞭增彊SRVCC、SDS、T-ADS流程中HLR/EPC HSS和IMS HSS之間交互的方法，使得上述VoLTE相關業務可以開展。

3GPP makes IMS HSS, HLR/EPC HSS as a unified HSS to describe the procedure when it solves some VoLTE relative services such as specification enhancement SRVCC, terminating service domain selection SDS, terminating access domain selection(T-ADS), etc. This generalized HSS has home server functions for all the domains. However, HLR/EPC HSS and IMS HSS are always deployed separately in the operators’ mobile networks, which makes these services unable to carry out if there is no interaction between HLR/EPC HSS and IMS HSS. Based on this problem, in the process of enhanced SRVCC, SDS and T-ADS, the method on the interaction between HLR/EPC HSS and IMS HSS is proposed to make the VoLTE relative services carry out.
