24.2593GPPPersonal Network Management (PNM)Release 17Stage 3TS
11.1 Introduction
The XML Configuration Access Protocol (XCAP) is used to create, read, write, modify and delete data related to the PNM service. XCAP uses the HTTP methods PUT, GET and DELETE for communication over the Ut reference point.
11.2 Roles
11.2.1 XCAP client
The XCAP client is a logical function as defined in IETF RFC 4825 [6]. The XCAP client provides the means to create, read, write, modify and delete the data used for the PNM services. In doing so, it shall generate an HTTP PUT, or an HTTP GET or an HTTP DELETE request in accordance with IETF RFC 7231 [25] and 3GPP TS 24.623 [18].
11.2.2 XCAP server
The XCAP server is a logical function as defined in IETF RFC 4825 [6]. The XCAP server stores all data relevant for the PNM services. When the XCAP server receives an HTTP PUT, HTTP GET or HTTP DELETE request for manipulating the data base, the XCAP server shall first authenticate the request in accordance with 3GPP TS 24.109 [5] and then perform authorization. Afterwards the XCAP server shall perform the requested action and generate a response in accordance with IETF RFC 7231 [25] and 3GPP TS 24.623 [18].
