This section explains the XCAP Server which allows a client to read, write, and modify application configuration data in their simservs document, a virtual XML document composed of user accessible portions of one or more HSS documents.
It uses OpenCloud’s Sh Cache Microservice to communicate with the HSS.

Example XCAP queries
XCAP Query Examples provide several examples of XCAP queries to get and modify the simservs document.
Normalization
The XCAP server tries to normalize any numbers contained in CDIV rule targets and ICB/OCB conditions before accepting the request. If any number cannot be normalized, the request is rejected. Normalization is done using the Normalization Component.
Normalization is controlled by the NormalizationEnabled profile attribute in the XCAPConfig profile in the XCAPConfigProfileTable profile table.
North American Numbering Plan Normalization
The XCAP server includes North American Numbering Plan (NANP) normalisation rules that can be
used to update the CDIV rule targets. The feature is activated using the NanpNormalizationEnabled property in
the XCAPConfig profile in the XCAPConfigProfileTable profile table.
The NANP normalization rules are as follows:
-
if the numbers length equals 10 and does not start with the country code then add the country code with international prefix.
For example if the number is '22333444445' then the CDIV target is set to '+122333444445'
-
if the numbers length equals 10 and starts with the country code e.g. '1' then add international prefix.
For example if the number is '1223334444' then the CDIV target set is to '+12233344444'.
MMTelCDIV Non-Provisionable Retarget URIs
The MMTelCDIV feature can be configured with a list of NonProvisionableRetargetURIs.
As the name implies, any XCAP request containing a diversion rule with a target equal to a URI on this list, after they are both normalized, is rejected.
Operator Determined Barring
When any request is received, the XCAP server checks if the subscriber is barred from using the XCAP server (due to Barring of Supplementary Services Management being set), or when updating diversion rules, is barred
from registering diverted numbers (Diverted to Address Registration Barring).
To do so, it queries the Sh Cache Microservice for the IMS-ODB-Information service indication.
If the XCAP server determines the request is not allowed, it is rejected with response code 403.
