AS Application Server IP-SM-GW IP-Short-Message-Gateway 4 Overview of SMS over IP functionality 4.1 Introduction SMS over IP functionality provides the UE with the capability of sending traditional short messages over IMS network. The architecture for SMS is specified in 3GPP TS 23.040 [3] and for SMS over IP functionality in 3GPP TS 23.204 [5]. 4.2 SMS over IP In order to guarantee SMS interoperability the SM-over-IP sender, the SM-over-IP receiver and the IP-SM-GW shall support encapsulation of RPDUs defined in 3GPP TS 24.011 [8], subclause 7.3. The SM-over-IP sender, the SM-over- IP receiver and the IP-SM-GW shall use the MIME type "application/vnd.3gpp.sms" for this purpose. 4.3 Application utilisation of SMS over IP SMS over generic IP access can be used to support all applications and services that use SMS. 4.4 SMS over IP and subscription without MSISDN When SMS over IP is to be delivered to a subscriber where the subscription profile does not contain an MSISDN, then there is a need for the IP-SM-GW to become aware of the IMSI during IMS registration for later correlation of short messages. In order to do so the IP-SM-GW derives the IMSI from the private user identity of the user that the UE includes in the REGISTER request at registration or if the private user identity is not available, derives the IMSI from the public user identity. 3GPP TS 23.003 [22] defines the relationship between the private user identity and the IMSI and the relationship between the public user identity and the IMSI. 5 SIP related procedures 5.1 Introduction 5.2 Functional entities 5.2.1 User Equipment (UE) A UE may implement the role of an SM-over-IP sender (see subclause 5.3.1) or an SM-over-IP receiver (see subclause 5.3.2). A mechanism for the home operator to configure the UE to use SMS over IP is given in 3GPP TS 24.167 [8A]. Additional parameters such as the PSI of the SC of the SM-over-IP sender can be obtained from ETSI 3GPP TS 24.341 version 11.2.0 Release 11 9 ETSI TS 124 341 V11.2.0 (2013-01) the UICC as per 3GPP TS 31.103 [18] and 3GPP TS 31.102 [19] if used or from the SIM as per 3GPP TS 51.011 [20] if used. NOTE: The capability of sending short messages over IP does not affect current limitations, thus the UE is limited to send at most one UE originated SM and to receive at most one UE terminated SM at a time. 5.2.2 Application Server (AS) An AS may implement the role of an IP-SM-GW (see subclause 5.3.3). 5.3 Roles 5.3.1 SM-over-IP sender 5.3.1.1 General In addition to the procedures specified in subclause 5.3.1, the SM-over-IP sender shall support the procedures specified in 3GPP TS 24.229 [10] appropriate to the functional entity in which the SM-over-IP sender is implemented. The SM- over-IP sender shall build and populate RP-DATA message, containing all the information that a mobile station submitting an SM according to 3GPP TS 24.011 [8] would place, for successful delivery. The SM-over-IP sender shall parse and interpret RP- DATA, RP-ACK and RP-ERROR messages, containing all the information that a mobile station receiving an SM according to 3GPP TS 24.011 [8] would see, in a SM submission or status report. 5.3.1.2 Submitting a short message When an SM-over-IP sender wants to submit an SM over IP, the SM-over-IP sender shall send a SIP MESSAGE request with the following information: a) the Request-URI, which shall contain the PSI of the SC of the SM-over-IP sender; NOTE 1: The PSI of the SC can be SIP URI or tel URI based on operator policy. The PSI of the SC can be obtained using one of the following methods in the priority order listed below: 1) provided by the user; 2) if UICC is used, then: - if present in the ISIM, then the PSI of the SC is obtained from the EF in DF_TELECOM of PSISMSC the ISIM as per 3GPP TS 31.103 [18]; - if not present on the ISIM, then the PSI of the SC is obtained from the EF in PSISMSC DF_TELECOM of the USIM as per 3GPP TS 31.102 [19]; or - if neither present on the ISIM nor on the USIM, then the PSI of the SC contains the TS-Service- Centre-Address stored in the EF in DF_TELECOM as per 3GPP TS 31.102 [19]. If the PSI of SMSP the SC is based on the E.164 number from the TS-Service-Centre-Address stored in the EF in SMSP DF_TELECOM then the URI constructed can be either a tel URI or a SIP URI (using the "user=phone" SIP URI parameter format). 3) if SIM is used instead of UICC, then the PSI of the SC contains the TS-Service Centre Address stored in the EF in DF_TELECOM as per 3GPP TS 51.011 [20]. If the PSI of the SC is based on the SMSP E.164 number from the TS-Service-Centre-Address stored in the EF in DF_TELECOM then the SMSP URI constructed can be either a tel URI or a SIP URI (using the "user=phone" SIP URI parameter format); or 4) if neither the UICC nor SIM is used, then how the PSI of the SC is configured and obtained is through means outside the scope of this specification. b) the From header, which shall contain a public user identity of the SM-over-IP sender; ETSI
