4 Supported supplementary services

22.0043GPPGeneral on supplementary servicesRelease 17TS

Table 4.1/3GPP TS 22.004 gives a list of possible supplementary services implemented in the PLMN, the definitions of which are given in the specifications [6]-[18].

NOTE: All supplementary services in this table are implemented in the PLMN. Subscribers can use these supplementary services for calls within the PLMN, but also in interworking situations with the PSTN (if supported) and the ISDN. In interworking situations with CSPDN and PSPDN these supplementary services can only be used during call set up (e.g. call forwarding services). When a call is established between an MS and a PDN, the MS acts as a data network terminal and can consequently only use the supplementary services that are supported by the relevant PDN. The PDN supplementary services are not described in this Specification; they can be found in the relevant PDN Specifications. However, the interworking situations with PDNs still require further study.

It has been identified as a requirement that the man‑machine interface in PLMNs regarding supplementary services should be compatible as much as possible with the man‑machine interface in the fixed networks as defined in CEPT groups, e.g. the same use of keypad information or function keys.

Table 4.1/ 3GPP TS 22.004 lists the categories for all supported supplementary services. Below the abbreviations used are listed.

Registration:

p = as a result of provision

a = service provider controlled procedure

s = subscriber controlled procedure

‑ = not applicable

Erasure:

w = as a result of withdrawal

s = subscriber controlled procedure

r = due to new registration

‑ = not applicable

Activation:

p = as a result of provision

r = as a result of registration

s = subscriber controlled procedure

a = service provider controlled procedure

c = when the conditions in the subscription options are met

‑ = not applicable

Deactivation:

w = as a result of withdrawal

s = subscriber controlled procedure

a = service provider controlled procedure

e = as a result of erasure

n = when the conditions in the subscr. options are not met

c = at the end of a per call basis activation

‑ = not applicable

Invocation:

n = automatic invocation by the network as a result of a particular condition

u = user invocation, by means of a control procedure

‑ = not applicable

Interrogation:

s = status check

dr = data request

‑ = not applicable

4.1 Support of Line identity services

A PLMN which supports the CLIP service shall also support the CLIR service. A PLMN which supports CoLP service shall also support the CoLR service.

A PLMN which does not support the CLIR service shall ensure that the line identity of a subscriber shall not be displayed to the called party unless the called party has CLIR override capability. A PLMN which does not support the CoLR service shall ensure that the line identity of a subscriber shall not be displayed to the calling party unless the calling party has CoLR override capability.

4.2 Support of Name identity services

(CNAP): A PLMN which supports the CNAP service shall also support the CLIR service.

A PLMN which does not support the CLIR service shall ensure that the name identity of a subscriber shall not be displayed to the called party.
