In. order. to. implement. applications. efficiently,. the. 3GPP. (3rd. Generation. Partnership.Project).has.standardized.OSA.(open.service.access).as.a.flexible. framework.so.that.application.developers.would.be.able.to.implement.various.applications.by.making.use.of.network.functionalities.in.the.CS.(circuit. switch),.PS.(packet.switch),.and.IMS.domains..Application.developers.could. access.network.functionalities.through.the.standardized.OSA.API.(application.programming. interface).offered.by. the.SCS. (service.capability.server). (Figure.8.1).
