ITU-T Q.3053 (03/2017) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sect

12、or (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every

13、 four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview,

14、 the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntar

15、y. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the n

16、egative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the

17、 use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendat

18、ion, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:

22、 NGN 1 Scope This Recommendation specifies the signalling architecture for Internet protocol (IP) based short message service (SMS) over next generation network (NGN), and identifies the signalling requirements for the interworking between NGN and mobile networks supporting SMS. The IP-based short m

23、essage over NGN is encapsulated in accordance with the SMS layer defined in ETSI TS 124 011. With regard to SMS over mobile networks, this Recommendation conforms to ETSI TS 123 040 and TIA-637 which specifies the technical implementation of SMS in circuit switch (CS) domain of GSM/UMTS networks and

24、 cdma2000 network. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

A “Circuit Switch type of connection“ is a connection for w

32、hich dedicated network resources are allocated at the connection establishment, and are released at the connection release.

Figure 5-1 Architecture model for providing IP-based SMS over NGN Figure 5-1 illustrate

37、s the functional entities providing IP based SMS. The functions of user equipment (UE), proxy call session control functional entity (P-CSC-FE), serving call session control functional entity (S-CSC-FE) and service user profile functional entity (SUP-FE) are identified in ITU-T Y.2012. The functiona

38、l entities in CS domain of a global system for mobile communication/universal mobile telecommunications system (GSM/UMTS) are defined in ETSI TS 123 040 and ETSI TS 123 204. The functional entities in CS domain of cdma2000 are defined in TIA-1109. 5.2 Functional entities in support of IP based SMS W

39、ith regard to IP based SMS, some functional entities are enhanced as described in the following. The UE of next generation networks (NGN) supports the encapsulation and de-encapsulation of relay protocol data units (RPDUs) in an IP- based SMS as defined in ETSI TS 124 011. The P-CSC-FE receives the

40、IP based short message from a NGN user, and deliveries the IP based short message to a NGN user. The S-CSC-FE executes the third party registration and de-registration of a NGN user supporting IP based SMS. The S-CSC-FE also receives and deliveries the IP based SMS message from and to a NGN user. Th

41、e SUP-FE stores the IP based SMS subscription data, the registration status, the authentication and authorization information and the routing information of a NGN user. IP short message gateway (IP-SM-GW) for transport layer interworking provides the protocol interworking between NGN and CS domain o

42、f GSM/UMTS and cdma2000 networks. It provides the 4 Rec. ITU-T Q.3053 (03/2017) protocol interworking for the transfer of short messages between a NGN user and a CS domain user, and for the status reports of SMS. IP-SM-GW acts as an application server (AS) in NGN. It supports the third party registr

43、ation procedure of a NGN user and stores the registration status of a NGN user. 5.3 Reference points The clauses below describe the required enhancements and specific considerations to existing reference points in order to support SMS over NGN. 5.3.1 Reference point between the IP-SM-GW and the SUP-

44、FE: A-S6 The reference point between the IP-SM-GW and the SUP-FE is used for: Supporting the registration and de-registration from the IP-SM-GW to the SUP-FE for short message delivery. Forwarding of the send routing information for a short message from SUP-FE to IP-SM-GW in order to retrieve the ad

45、dress where the short message should be forwarded. Interrogating the SUP-FE using send routing information for a short message to retrieve the international mobile subscriber identity (IMSI) and the current mobile switching centre (MSC) address. Informing the SUP-FE when memory capacity exceeded con

46、dition occurs or ceases. Retrieving SMS related data from the SUP-FE: subscriber data of the short message service and additional service data on the service authorisation of the encapsulated short message delivery via NGN, and service centre (SC) address for service-level interworking from IP-based

47、 short message to CS-based short message if the SC address is stored in the SUP-FE. The reference point A-S6 is recommended to use DIAMETER protocol as per IETF RFC 3588. 5.3.2 Reference points between the IP-SM-GW and the S-CSC-FE: A-S4 The reference point between the IP-SM-GW and the S-CSC-FE is u

48、sed for: transferring of short messages between IP-SM-GW and the S-CSC-FE via NGN; supporting of registration and deregistration of NGN users for SM delivery. The reference point A-S4 is recommended to use session initiation protocol (SIP) as per ETSI TS 124 229. 5.3.3 Reference point between the IP

49、-SM-GW and the SMS-GMSC: E1 The reference point between the IP-SM-GW and the SMS-GMSC is used for: Connecting to the SMS-GMSC, acting as a MSC towards a SMS-GMSC within GSM/UMTS networks defined in 3GPP. The reference point E1 is recommended to use mobile application part (MAP) over No.7 signaling as per ETSI TS 129 002. 5.3.4 Reference point between the IP-SM-GW and the SMSC: E2 The reference point between the IP-SM-GW and the short message service centre (SMSC) is used for:
