SMS enables a user to send and receive Short Messages (SMs) to and from another user. <\/p>\n<p>This service is based on GSM 03.40. The Service Centre functionality described in this International Standard is equal to the functionality of a Service Centre in GSM 03.40. Thus, for interoperability with a GSM network, it is only necessary to implement a QSIG interface. <\/p>\n<p>NOTE 1 &#8211; The interworking with other air interfaces is not precluded, but is outside the scope of this International Standard. <\/p>\n<p>NOTE 2 &#8211; The Short Message Service is a special kind of basic service but is described in this document in the style of a supplementary service. Supplementary service specifications are produced in three stages, according to the method described in ETS 300 387. <\/p>\n<p>This International Standard contains the stage 1 and stage 2 specifications of SMS. The stage 1 specification (clause 6) specifies the service as seen by users of PISNs. The stage 2 specification (clause 7) identifies the functional entities involved in the service and the information flows between them.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Information Technology &#8211; Telecommunications and Information Exchange Between Systems &#8211; Private Integrated Services Network &#8211; Specification, Functional Model and Information Flows &#8211; Short Message Service<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/csa\/\"><b>CSA<\/b><\/a><\/td>\n<td>2004<\/td>\n<td>50<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":514930,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[599,2674],"product_tag":[],"class_list":{"0":"post-514918","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-33-040-35","7":"product_cat-csa","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/514918","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/514930"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=514918"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=514918"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=514918"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
