Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

The XCAP connection parameters policy consists of zero or more XCAP connection parameters policy parts.

The XCAP connection parameters policy part consists of an access identifier and an XCAP connection parameters reference. The XCAP connection parameters reference refer to an instance of the <X> interior node specified in OMA-TS-XDM_Core-V1_1-20080627-A [14].

The UE may support the XCAP connection parameters policy.

If the UE supports the XCAP connection parameters policy:

1) if the UE intends to send an XCAP request using an access identified by an access identifier of a XCAP connection parameters policy part, the UE shall send the XCAP request according to the XCAP connection parameters referenced by the XCAP connection parameters reference of the XCAP connection parameters policy part; and

2) the UE may support being configured with the XCAP connection parameters policy using one or more of the following methods:

a) the EF_{XCAPConfigData} file described in 3GPP TS 31.102 [15B];

b) the EF_{XCAPConfigData} file described in 3GPP TS 31.103 [15A]; and

c) in the XCAP_conn_params_policy node of 3GPP TS 24.424 [22]

If the UE is configured with both XCAP_conn_params_policy node of 3GPP TS 24.424 [22] and the EF_{XCAPConfigData} file described in 3GPP TS 31.102 [15B] or 3GPP TS 31.103 [15A], then the EF_{XCAPConfigData} file shall take precedence.

NOTE: Precedence for files configured on both the USIM and ISIM is defined in 3GPP TS 31.102 [15B].

If the UE does not support the XCAP connection parameters policy, in order to manipulate XCAP resources stored on the XCAP server, a UE can be configured with parameters describing a connection to be used for XCAP. Connection parameters can be configured as specified in appendix C in OMA-TS-XDM_Core-V1_1-20080627-A [14].
