Served network: GSM and UMTS
Brief introduction:
The function is used to restrict a special number being HOLD, passively being added to the
multiparty service (MPTY), or passively serving as an ECT diverting party.Description:
The function is used to restrict a special number being HOLD, passively being added to theMPTY, or passively serving as an ECT diverting party. It aims to prevent illegal subscribers
from deceiving by using the network supplementary service function. For example, cheater A
dials the number of cheatee B who has a rechargeable card, holds B, and dials 0850. Afterdialing 0850, A enters his own MSISDN according to the voice prompt first, and then sets upthe MPTY. B listens to the alert tone, requiring him to enter the information of the
rechargeable card. Thus when B completes the operation, the money in the card is put on the
account of A. This function can restrict this deceiving method, greatly reducing theprobability of subscribers being deceived. It only supports the restriction function of
supplementary services HOLD, MPTY and ECT.In the service, you can set self-defined properties 36, 37 and 38 for special numbers by settingthe subscriber service property data to restrict HOLD, MPTY, and ECT respectively. When a
calling subscriber calls a special number, since the subscriber service property data is matched,and restricting HOLD, MPTY, and ECT is set, the calling subscriber cannot perform the
operation of HOLD, MPTY, and ECT.
Typical application scenario:
The function supports subscribers to directly dial some specific numbers which restrict
the three supplementary services such as HOL D, MPTY, and ECT.
1: A calls B, or B calls A, and A originates call hold after call completion.
If B is a restricted subscriber, the HOLD operation of A to B fails.
2: A calls B, and A originates call hold after call completion.
A calls C, and A originates the MPTY or ECT service after call completion.
If B is not a restricted subscriber, while C is a restricted subscriber, the MPTY or ECT serviceoriginated by A fails after C is put through.
3: B calls A, and A originates the call hold after call completion.
A calls C, and A originates the MPTY or ECT service after call completion.
If C is a restricted subscriber, the multi-connection request of A fails.
4: A calls B, and A originates call hold after call completion.
C calls A, and A originates the MPTY or ECT service after call completion.
If C is a restricted subscriber, the multi-connection request of A fails.
The MPTY also contains adding new subscribers to the existing meeting.
Through the forwarding mode, the function supports transferring subscribers to some
specific numbers which restrict the three supplementary services such as HOLD, MPTY,
and ECT.

When subscribers are transferred to some specific numbers such as 0850 through the
forwarding mode, the three supplementary services such as HOLD, MPTY, and ECT can be
transplanted. That is, restrict the function of HOLD, MPTY or ECT according to the latestput-through numbers, but not the intermediate numbers of subscribers. In which, theforwarding contains intra-office forwarding and other office forwarding.
In addition, the function of whether to restrict these supplementary services is related to callsformed by subscriber dialing some specific numbers. When these calls are released, it is not
required to restrict the function. For example, subscriber A dials and holds B who is not a
restricted subscriber, and then dials C who is a restricted subscriber. At this time, it is notallowable for A to originate HOLD, MPTY or ECT. When A releases the call between A andC, and then dials D who is not a restricted subscriber, A can originate HOLD, MPTY or ECT
after call completion.
Service benefit:
For operators
The supplementary service restriction function makes operators restrict malicious subscribersto deceive through supplementary services provided by the network, thus improving
subscriber satisfaction.
For subscribers
It greatly reduces the probability of subscribers being deceived.
Requirements for peripheral network entities:
The supplementary service restriction function only involves the requirements of the MSC.
For the service, the originating office (V)MSC mainly completes different signaling
processing and data analysis of relevant calls.

1.3 Operator Determined Barring (ODB) services
WMFD-030000Function name: Operator Determined Barring (ODB) services
Description:
ODB is controlled by network operators, and is implemented through HLR data management.The main purpose is that the operators restrict the call capabilities of subscribers based on
different characteristics, especially in economic capability to ensure that operators will not
suffer serious loss about the conversation fees.
ODB is applicable for all the user terminal service and bearer service except the emergencycalls. Compared with the above mentioned SS, ODB provides higher priority. When the two
services conflict, the above-mentioned supplementary service will be prohibited.
Both ODB and call restriction SS implement barring service. The differences are as follows:
z The former subscriber state is controlled by operators, but that of the latter is controlledby the subscriber himself or the operator.
z The former can be activated upon the provision, but the latter is activated after thesubscriber activates it.

Description:
Temporary Mobile Subscriber Identity (TMSI) is managed by MSC/VLR. TMSI re-allocationaims to ensure IMSI security through using TMSI in the air radio interface to prevent the
Third Party from tracing the subscriber activities through IMSI.
When the subscriber enjoys the services in the area controlled by a MSC/VLR, MSC/VLRallocates a TMSI identifying the subscriber uniquely at this MSC/VLR based on the special
principle of TMSI allocation for the subscriber. So the network identifies the subscriber
through the TMSI, all the exchange of signaling and data does not use IMSI again for the
purpose of security.

With the CHECKIMEI function, IMEI can be obtained from the mobile equipment and sent tothe EIR to further check the equipment status.
In the function configuration table, there is an item indicating whether the built-in EIR
function is supported. If built-in EIR is supported, grey list subscribers and black list
subscribers can be configured. Those subscribers not configured are treated as white listsubscribers by default. If a subscriber is a black list subscriber, the CHECKIMEI fails, and asa result, location update of the subscriber and service processing are rejected. If a subscriber is
a grey list subscriber, location update of the subscriber is allowed. During the service
processing, if the grey list subscriber is a calling party and the tone play is configured in theMAP function configuration table, the tone is played. After the tone is played, whether the call
is connected is determined by the MAP function configuration table. If tone play is notconfigured in the MAP function configuration table, the tone is not played and the call is
directly connected. If the grey list subscriber is a called party, no special processing is used.
The maximum volume of build-in EIR is 20,000.

1.8 Handover functions
WMFD-080000
Function name: Handover functions
Description:
Support the channel handover because of radio acceptance level, channel, quality, distance
and traffic during the call setup or completion of call setup.
Avoid the call drop because of terminal mobility, radio quality and coverage, and enable the
subscriber to obtain satisfactory conversation quality or reduce partial system congestion.
Generally, the handover is originated by radio access network.
In respect of GSM network and UMTS network, the handovers provided by MSOFTX3000
for network side: intra-GSM handover, intra-UMTS handover, inter-UMTS handover andinter-GSM handover.
In respect of MSC, the handovers implemented by MSC include: Intra-MSC handover,
inter-MSC handover and subsequent handover.
Intra-MSC handover: Radio channel of mobile subscriber is switched from current BSS/RNSto another BSS/RNS of the same MSC. The completion of handover is controlled by one
MSC. The intra-MSC handover can be divided into MSCa intra handover and MSCb intra
handover according to whether the MSC is controlling MSC. When the handover happens inthe controlling MSC, the handover is called MSCa intra handover, and MSCb intra handover
when it happens on the non-controlling MSC.
Inter-MSC handover: To keep the conversation, mobile subscriber is switched from BSS/RNScoverage of one MSC to the BSS/RNS coverage of another MSC.
For inter-MSC handover, the controlling MSC(MSCa ) controls the whole handoverprocedure. Firstly the relocation command is reported by the RNC to the MSCa, then MSCa
will choose the target MSC and send the handover resource requirement to the target MSCb.
Then the bearer between the two MSCs is built up. The MSCb will handle the allocation ofnecessary radio resources for handover procedure and finish the subsequent call control withthe assistant from the MSCa.
Subsequent handover: After basic handover of mobile subscriber is successful, inter-MSC
handover is generated again during the continuous conversation. According to different
handover destinations, subsequent handover includes: Subsequent handover to anchor MSCand subsequent handover to the Third Party MSC.
