1 Definition
The user scrambling is a service to scramble the information between the PS and the network.
2 Description
2.1 General Description
The scrambling can be made between the PS and the network to the information bit by the scrambling
service. This service is provided under active station, and the scrambling to the bi-directional
information bit is possible from the PS to the network and in the reverse order. The bearer capability
under the active station has no restriction.
2.2 Specific Terminology
None identified.
2.3 Qualifications on the Applicability to Telecommunication Service
None identified.
3 Procedures
3.1 Provision/withdrawal
This service is provided parallel to the PHS communication service.
3.2 Normal procedures
3.2.1 Activation/Deactivation/Registration
User scrambling is activated by subscription.
3.2.2 Invocation and Operation
3.2.2.1 Invocation
This service and PHS communication occurs simultaneously. The encryption key which is necessary
for scrambling is established before switch to active on PS side and notify to the network. An specificencryption key has no user scrambling effect at all, and information bit is beard as it is.
3.2.2.2 Operation
Before the translation to communication, PS delivers the establishing encryption key to network (CS).
As a result, PS and network (CS) share the common encryption key. During the communication, PSgenerates the scramble pattern based on the method specified by the encryption key, and carries
out scrambling by adopting exclusive OR with information bit. The message used in User scramblingis the fixed message of encryption key, which is prescribed on the air-interface.

3.3.1 Activation/Deactivation/Registration
None identified.
3.3.2 Invocation and Operation
None identified.
3.4 Alternative Procedures
None identified.
4 Network Capability for ChargingCharging principle is out of the specification described in the document.
5 Interworking Requirement
User scrambling is irrelevant to the interworking as User scrambling is a closed function only
between a PS and the network.
6 Interaction with other supplementary services
6.1 Calling User Identification Presentation (CUIP)
No impact, i.e. neither supplementary service affects the operation of the other supplementary service.
6.2 Calling User Identification Restriction (CUIR)
No impact, i.e. neither supplementary service affects the operation of the other supplementary service.
6.3 Call forwarding
6.3.1 Call Forwarding Unconditional (CFU)
No impact, i.e. neither supplementary service affects the operation of the other supplementary service.
6.3.2 Call Forwarding on PS Busy (CFB)
No impact, i.e. neither supplementary service affects the operation of the other supplementary service.
6.3.3 Call Forwarding on No Reply (CFNRy)
No impact, i.e. neither supplementary service affects the operation of the other supplementary service.
