The SCF uses the XML communication module to interact with service capability (SC), which is the bearer to realize services by implementing the SC service logic module. The SC service logic interacts with mobile core network through the session initiation protocol (SIP)\u2010based session control module and the SIP Callback module.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>The push to talk over cellular service is used to illustrate how the proposed OSA SCS interacts with the AS and the mobile core network elements.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Practical implications<\/jats:title><jats:p>In the design, when implementing a new service (i.e. to create a new SCS), one only needs to create the Callback module and the Service Logic modules, and other SC\/SCF modules can be reused.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>Through this modulized SCS design, the OSA service deployment can be speeded up.<\/jats:p><\/jats:sec>","DOI":"10.1108\/17427370810911612","type":"journal-article","created":{"date-parts":[[2008,9,27]],"date-time":"2008-09-27T07:08:01Z","timestamp":1222499281000},"page":"268-278","source":"Crossref","is-referenced-by-count":3,"title":["An OSA service capability server for mobile services"],"prefix":"10.1108","volume":"4","author":[{"given":"Imrich","family":"Chlamtac","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hsin\u2010Yi","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi\u2010Bing","family":"Lin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meng\u2010Hsun","family":"Tsai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"140","reference":[{"key":"key2022013119545383000_b1","unstructured":"3GPP (2007a), \u201c3rd generation partnership project; technical specification group core network; open service access (OSA); application programming interface (API); part 1: overview (release 7)\u201d, Technical Specification 3G TS 29.198\u20101 version 7.0.0, March."},{"key":"key2022013119545383000_b2","unstructured":"3GPP (2007b), \u201c3rd generation partnership project; technical specification group core network; customised applications for mobile network enhanced logic (CAMEL) phase 4; stage 2 (release 7)\u201d, Technical Specification 3G TS 23.078 version 7.9.0, September."},{"key":"key2022013119545383000_b3","unstructured":"3GPP (2007c), \u201c3rd generation partnership project; technical specification group service and system aspects; IP multimedia subsystem (IMS); stage 2 (release 8)\u201d, Technical Specification 3G TS 23.228 version 8.5.0, June."},{"key":"key2022013119545383000_b4","unstructured":"Chou, C.\u2010M. and Lee, H.\u2010Y.
