1 Barring of All Outgoing Calls(BAOC)
1.1 Definition
The Supplementary service Barring of All Outgoing Calls enables a user to bar outgoing calls.
However, this service does not restrict the reception of incoming calls.
1.2 Description
1.2.1 General description
The user may subscribe for each basic service or collectively for all basic services.
For each of the basic services, the subscriber may bar all originating calls except some special
numbers (e.g. police, fire brigade).
Note - The service provider decides which numbers are not barred.
1.2.2 Specific terminology
No specific terminology identified.
1.2.3 Qualifications on the applicability to telecommunication services
No restrictions identified.
1.3 Procedures
1.3.1 Provision/withdrawal
BAOC shall be provided after prearrangement with the service provider.
A codeword is allocated by the service provider for each basic service and each subscriber. Upon
subscribes request, a unique codeword may be allocated for all basic services at the subscriber access.
Note - Different subscribers may obtain the same codeword independently.
1.3.2 Normal procedures
1.3.2.1 Activation/deactivation/registration
A user who has subscribed to BAOC can use the activation procedure.
For the activation of one version of BAOC for one basic service, the appropriate codeword has to bereceived by the PHS network of the subscriber.
When the user activates BAOC the service provider will return notification of acceptance or rejectionof the request (compare exceptional procedures, 1.3.3.1.1 for possible causes of rejection).
For the deactivation of a previously activated BAOC, the same codeword has to be received by the

B-SV2.20-01-TS

PHS network.
When the user deactivates BAOC, the service provider will return notification of acceptance orrejection of this request (compare exceptional procedures, 1.3.3.1.1, for possible causes of rejection).
1.3.2.2 Invocation and operation
When BAOC is active, outgoing call attempts will be examines by the PHS network. They will beprocessed further in and beyond the PHS network, if they are within the limitations of the version of
BAOC that has been activated.
When a user attempts to set up a call to a destination which is batted by BAOC that is currently
active, the call set-up will not be completed. The service provider may give a notification of theactivation of BAOC to the user.
1.3.3 Exceptional procedures
1.3.3.1 Activation/deactivation/registration
1.3.3.1.1 Activation
If the PHS network cannot accept an activation request, the user may receive a notification that
BAOC activation was unsuccessful.
The following are possible causes as an example, so the application is a network provider option.
(1) service not subscribed;(2) insufficient information;(3) unallocated codeword;
A certain number of activation attempts (e.g. 3) with am unallocated codeword may result in a
temporary ignoration of further activation attempts(e.g. 30 minutes).
(4) service already activated.
In this case, treatment of consecutive attempts to activate BAOC are a network provider option.
1.3.3.1.2 Deactivation
If the PHS network cannot accept a deactivation request, the user may receive a notification that
BAOC deactivation was unsuccessful.
The following are possible causes as an example, so the application is a network provider option.
(1) service not subscribed;(2) insufficient information;(3) unallocated codeword;
A certain number of deactivation attempts (e.g. 3) with an unallocated codeword may result in a
temporary ignoration of further deactivation attempts (e.g. 30 minutes).
(4) service not activated.
In this case, treatment of consecutive attempts to deactivate BAOC are a network provider
option.

A user who has subscribed to BIC-roam can use the activation procedure. For the activation of BAICroam for one basic service, the appropriate codeword has to be received by the PHS network.
When the user activates BIC-roam the service provider will return notification of acceptance orrejection of the request (compare exceptional procedures, 5.3.3.1.1, for possible causes of rejection).
For the deactivation of a previously activated BIC-roam, the same codeword has to be received by the
PHS network.
When the user deactivates BIC-roam, the service provider will return notification of acceptance orrejection of this request (compare exceptional procedures, 5.3.3.1.1,for possible causes of rejection).
5.3.2.2 Invocation and operation
When BIC-roam is active, outgoing call attempts will be examined by the PHS network. They will beprocessed further in and beyond the PHS network, if they are within the limitations of the version of
BIC-roam that has been activated.
When a user is barred by BIC-roam that is currently active, the call fron calling user will not becompleted. The service provider may give a notification of the activation of BAIC to the user.

If the PHS network cannot accept an activation request, the user may receive a notification that BICroam activation was unsuccessful.
The followings are possible causes as an example, so the application is a network provider option.
(1) service not subscribed;(2) insufficient information;(3) unallocated codeword;
A certain number of activation attempts (e.g. 3) with an unallocated codeword may result in a
temporary ignoration of further activation attempts(e.g. 30 minutes).
(4) service already activated.
In this case, treatment of consecutive attempts to activate BIC-roam are a network provider
option.
5.3.3.1.2 Deactivation
If the PHS network cannot accept a deactivation request, the user may receive a notification that BICroam deactivation was unsuccessful.
The following are possible causes as an example, so the application is a network provider option.
(1) service not subscribed;(2) insufficient information;(3) unallocated codeword;
A certain number of deactivation attempts (e.g. 3) with an unallocated codeword may result in a
temporary ignoration of further deactivation attempts (e.g. 30 minutes).
(4) service not activated.
In this case, treatment of consecutive attempts to deactivate BIC-roam are a network provider
option.

BIC-roam should have priority over CUIP, and calling user may receive a notification that the call isbarring. In this cace there exists no interaction between the two sevices.
5.6.2 Calling User Identification Restriction (CUIR)
Same as CUIP.
5.6.3 Call forwarding
5.6.3.1 Call Forwarding Unconditional (CFU)
When the CFU has been activated prior to the activation of BIC-roam, the calls are forwarded
regardless of BIC-roam that has been activated, i.e. in this case there exists no interaction between thetwo services.
After BIC-roam has been activated, calls can only be forwarded to destinations which are within thelimitations of the BIC-roam that has been activated.
5.6.3.2 Call Forwarding on PS Busy (CFB)
Same as CFU.
5.6.3.3 Call Forwarding on No Reply (CFNRy)
Same as CFU.
5.6.3.4 Call Forwarding on PS Not Reachable (CFNRc)
Same as CFU.
5.6.4 Call barring
5.6.4.1 Barring of All Outgoing Calls (BAOC)
No impact. i.e. neither supplementary service affects the operation of the other supplementaly
services.
5.6.4.2 Barring of Outgoing International Calls (BOIC)
No impact. i.e. neither supplementary service affects the operation of the other supplementaly
services.
5.6.4.3 Barring of Outgoing International Calls except call to Home Country (BOIC-exHC)
