3GPP TS 23501-g51 中英文对照 | 4.4.2 SMS over NAS

Posted 2021-09-07 COCOgsta

个人在学习5G标准3GPP TS 23501-g51过程中，也发现google的机器翻译实在晦涩难懂，所以个人在借助百度翻译（中国人更懂中文）的同时，人工对每句话进行了校对。

在自己学习的同时，也将翻译内容分享给给广大网友。由于个人能力有限，翻译不到位的地方还请各位网友们指正。

4.4.2 SMS over NAS

4.4.2.1 Architecture to support SMS over NAS

Figure 4.4.2.1-1 shows the non-roaming architecture to support SMS over NAS using the Service-based interfaces within the Control Plane.

图4.4.2.1-1显示了使用Control Plane内Service-based的接口支持NAS SMS的non-roaming体系结构。

Figure 4.4.2.1-2 shows the non-roaming architecture to support SMS over NAS using the reference point representation.

图4.4.2.1-2显示了使用参考点表示法支持NAS上SMS的non-roaming体系结构。

NOTE 1: SMS Function (SMSF) may be connected to the SMS-GMSC/IWMSC/SMS Router via one of the standardized interfaces as shown in TS 23.040 [5].

注1：SMS Function（SMSF）可通过TS 23.040[5]中所示的一个标准化接口连接到SMS-GMSC/IWMSC/SMS Router。

NOTE 2: UDM may be connected to the SMS-GMSC/IWMSC/SMS Router via one of the standardized interfaces as shown in TS 23.040 [5].

注2：UDM可通过TS 23.040[5]中所示的标准化接口之一连接到SMS-GMSC/IWMSC/SMS Router。

NOTE 3: Each UE is associated with only one SMS Function in the registered PLMN.

NOTE 4: SMSF re-allocation while the UE is in RMREGISTERED state in the serving PLMN is not supported in this Release of the specification. When serving AMF is re-allocated for a given UE, the source AMF includes SMSF identifier as part of UE context transfer to target AMF. If the target AMF, e.g. in the case of inter-PLMN mobility, detects that no SMSF has been selected in the serving PLMN, then the AMF performs SMSF selection as specified in clause 6.3.10.

注4：本规范版本不支持UE在服务PLMN中处于RM-REGISTERED状态时SMSF re-allocation。当为给定UE re-allocated服务AMF时，源AMF包括SMSF标识符，作为到目标AMF的UE上下文传输的一部分。如果目标AMF（例如，在inter-PLMN移动性的情况下）检测到服务PLMN中没有选择SMSF，则AMF按照第6.3.10条的规定执行SMSF选择。

NOTE 5: To support MT SMS domain selection by IP-SM-GW/SMS Router, IP-SM-GW/SMS Router may connect to SGs MSC, MME and SMSF via one of the standardized interfaces as shown in TS 23.040 [5].

注5：为支持IP-SM-GW/SMS Router选择MT SMS域，IP-SM-GW/SMS Router可通过TS 23.040[5]中所示的标准化接口之一连接到SGs MSC、MME和SMSF。

4.4.2.2 Reference point to support SMS over NAS

N1: Reference point for SMS transfer between UE and AMF via NAS.

Following reference points are realized by service based interfaces:

N8: Reference point for SMS Subscription data retrieval between AMF and UDM.

N20: Reference point for SMS transfer between AMF and SMS Function.

N21: Reference point for SMS Function address registration management and SMS Management Subscription data retrieval between SMS Function and UDM.

N21：SMS Function与UDM之间的SMS Function地址注册管理和SMS Management Subscription数据检索的参考点。

4.4.2.3 Service based interface to support SMS over NAS

Nsmsf: Service-based interface exhibited by SMSF.
