Summary
Based on the forwarding cause, the CFB is classified into network determined user
busy (NDUB) and user determined user busy (UDUB). When a mobile subscriber
serves as the callee, if the subscriber is in a conversation (the line is busy due to
network cause) or the subscriber rejects the incoming call (the line is busy due to thesubscriber's cause), the call is forwarded to a third party. The third party can be either a
PLMN/PSTN/ISDN subscriber or a service console (such as voice mailbox).
Benefits For carriers
Carriers can forward calls more flexibly and increase call completion rate, thus
boosting the revenue. For subscribers
When the subscriber cannot use his/her MS, or does not want to use the MS, thesubscriber can forward an incoming call to another MS without affecting the
conversation. This service provides more options for the subscriber to enjoy the

Description
The HLR supports subscription or withdrawal, and activation or deactivation of this
service. The HLR stores the FTNs. If the location of a subscriber changes, the HLRsends the FTN to the VLR. If the subscriber receives a call when the subscriber's line
is busy, the VLR of the callee, knowing that the subscriber has subscribed to the callforwarding service, initiates a route setup request to the corresponding HLR according
to the FTN, and establishes a connection to the MSC of the third-party subscriber. Thesubscriber can activate the service through his/her mobile phone or in the business hall
of carriers.

Summary
The third party can be either a PLMN/PSTN/ISDN subscriber or a service console(such as voice mailbox).
Benefits For carriers
Carriers can forward calls more flexibly and increase call completion rate, thus
boosting the revenue.
For subscribers
If the MS of a subscriber is turned off or the quality of the signals received by theMS is poor, the subscriber can forward an incoming call to another MS without
affecting the conversation.
Description
The HLR supports subscription or withdrawal, and activation or deactivation of this
service. To use the service, the subscriber must register the service in the business hall
of carriers, and then activate the service. The subscriber can activate the servicethrough his/her mobile phone or in the business hall. When a subscriber is unreachable,
it involves two occasions:
The HLR has stored the information on the unreachable subscriber. For example,
when a subscriber remains offline for a long time, the HLR reconfigures the flag
bit of the subscriber to indicate that the subscriber is unreachable.
The HLR does not know the reason why the subscriber is unreachable. Forexample, the subscriber's MS is turned off or cannot receive any signals.
If the HLR knows the reason why the subscriber is unreachable, the MSC of the callercarries the FTN in the response message to the HLR's routing request message. In this
case, the MSC of the caller initiates a route request to the third-party subscriberaccording to the FTN in the returned message. If the HLR does not know the reason
why the subscriber is unreachable, it does not send the FTN to the MSC of the caller.
The MSC of the caller firs establishes a call connection to the MSC of the callee, andthe MSC of the callee then initiates a call route request to the HLR of the third-party
subscriber.

Summary
This function allows you to configure the forwarding service data in the HLR. When a
subscriber registers the forwarding service, FTNs of correct format can be generated
and stored in the databases of the HLR.
Benefits For carriers
The function allows carriers to configure the call forwarding service flexibly.
For subscribers
The function helps the subscriber to set a forwarded-to number.
Description
The request for registering the call forwarding service received by the HLR contains
FTNs. These FTNs adopt the following formats:
Unknown format (or domestic format): 81 + FTN inputted by the subscriber:
81 + fixed telephone number
81 + 0 + area code + fixed telephone number
81 + PLMN number
International format
91 + country code (CC)+ area code (AC)+ fixed telephone number 91 + PLMN number
Currently, the FTN registered in the MS adopts the unknown format. The HLR
regulates the received FTNs. The FTNs saved in the database and those sent to the MSadopt the international format. You can only judge the attribute of a regulated FTN, for
example, check whether the FTN is in the homeland or the FTN is in the local network.
To regulate the FTNs, you need to configure the related data in the HLR.
Enhancement
To enable the HLR to regulate the FTNs, you need to configure the following data:
Local office information
The table contains only one record, which describes the country code of the areawhere the HLR is located and HLR number. When it is necessary to know the
country code of an FTN but the FTN does not carry a country code, the HLR usesthe country code in the table as the country code of the regulated FTN.
Mapping of IMSIs and area codes
The table contains multiple records, with each record describing an IMSI prefix
and its corresponding area code. For example, the area code corresponding to the
IMSI prefix of 46000755 is 755. When it is necessary to know the area code of an

FTN but the FTN does not carry an area code, the HLR uses the area code in thetable as the area code of the regulated FTN.
Called number analysis
The table contains multiple records. Every record has four fields: prefix of the
FTN, attribute of the FTN, number of information station or not, and number ofentertainment station or not. There are four options for the FTN attribute: local
number, domestic toll call number, international toll call number, and PLMN
number. For example, 139 indicates PLMN number; 0 indicates domestic toll callnumber; 00 indicates international toll call number; 19 indicates local number.
In the FTN regulating process, the HLR compares the prefix of an FTN withrecords of the CALLEDNUM_ANALYSIS table to find a matched record, and
then regulates the FTN according to the record.
Area code
The table contains multiple records, with each record describing an area and its
corresponding area code, for example, the area code of Shenzhen city is 755.
Mapping of MSISDNs and area codes
The table contains multiple records, with each record describing an MSISDN
prefix and its corresponding area code. When analyzing a PLMN FTN, the HLR
queries the table to check whether the FTN exceeds area limitation imposed onthe call forwarding.
Country code
The table contains multiple records, with each record describing a country and its
corresponding country code. For example, the country code of China is 86. Whenanalyzing an FTN of international format, the HLR queries the table to verify
whether the FTN is a domestic number.
Forbidden forwarded-to number
The table contains multiple records, with each record describing a number that is
prohibited to be forwarded, for example, 110. When the HLR judges that anumber is a local number, it can query the table to verify whether the number is
allowed to serve as an FTN.
Dependency
The HLR9820 implements the function independently. There is no special requirement
for other NEs.

When the callee subscribes to the CLIP service, he/she can select whether to override
the calling number display restriction imposed by the caller. The CLIP and the CLIRare repulsive to each other. When the callee activates the CLIP service and the caller
activates the CLIR service, since the priority of the CLIR is higher than that of the
CLIP, the network does not display the calling number for the callee. However, whenthe CLIP service of the callee supports the OVERRIDECATEGORY attribute, thepriority of the CLIP is higher than that of the CLIR. In this case, the network displays

The timely suspension of services by carriers can prevent the call charge of thesubscriber from exceeding the limit.
Description
This service provides locking operation, allowing carriers to suspend the service of thedefaulting subscriber and avoid loss of call charges.
When carriers performs locking operations for the subscriber, it can control separately:
Whether to allow the subscriber to receive incoming calls.
Whether to allow the subscriber to make outgoing calls.
Whether to allow the subscriber to use the GPRS service.
Through the above control mechanisms, carriers can restrict the subscriber's services
flexibly.
EnhancementThe HLR provides two types of locks for suspending services of the defaulting
subscribers: lock for the MSC domain and lock for the PS domain. Select the desiredlock according to the network access mode (NAM) of the subscriber. If the NAM of
the subscriber is MSC and SGSN, after the subscriber's line is locked, the subscribercan only register service in the CS domain and is unable to initiate/receive a call and
perform USSD/GPRS operations. If the NAM of the subscriber is SGSN, after the

Summary
The location update service is a flow initiated by the subscriber's terminal for
maintaining subscriber data consistency between the VLR and the HLR.
Benefits For carriers
This service provides a basic network function.
For subscribers
None.
DescriptionThe subscription data, location information, and status information of the subscriber
are stored in the HLR. In this flow, the HLR sends all subscription data of the
subscriber to the VLR.
Enhancement
Location update is the major process of the location management, and is triggered by
the MS. In the GSM system, the HLR, VLR, and MS (or the SIM card) must know the
location information of the subscriber. When the location information changes, it is
necessary to maintain consistency among the HLR, VLR, and the MS.
When the MS finds a location area that can provide better service, it notifies theMSC/VLR of the new location area (generally, the MSC and the VLR are integratedinto a function entity). If the original location area and the new location area belong to
the same MSC/VLR, modify the location area information of the MS in the VLR; ifthey belong to different MSC/VLR, the new MSC/VLR must send a message to the
HLR for obtaining the data of the MS. The HLR sends the information to the new
MSC/VLR, and notifies the original MSC/VLR to delete the registration data of theMS, and registers the MS in the new MSC/VLR. Meanwhile, the HLR also updatesthe MSC/VLR number of the MS.
By checking whether the new MSC/VLR contains the records of the MS, the network
can tell whether the new location area and the original location area belong to the sameMSC/VLR. But the network must know the IMSI number of the MS. The IMSI
number can be obtained from the original VLR(PVLR) of the MS or the MS.
The following lists the several situations of location update:
Normal location update. It triggers location update flow.
Periodic location update
IMSI attached/detached
The VLR receives the service operation instruction from the MS when the flag bit
of the VLR indicates fault. It triggers location update flow.

2. The HLR/AuC receives the authentication request from the VLR/SGSN,generates the RAND, calculates the authentication vector (SRES, KC, andRAND), and sends it to the VLR/SGSN.
3. The MSC/VLR sends an authentication command (containing the RAND) to theMS. The MS calculates the SRESms based on the RAND and its own KI, and
sends a message with the SRESms as the response to the authentication request tothe MSC/VLR. If SRESms is equal to SRESauc, the subscriber is considered as alegal subscriber and passes the authentication. Otherwise, the subscriber fails topass the authentication, and is refused to access the network.
In the 3G GSM system, the authentication flow is as follows:
1. The VLR/SGSN receives the registration request from the MS, sends the IMSI ofthe subscriber to the HLR/AuC of the MS, and requests them to authenticate the
subscriber
2. The HLR/AuC receives the authentication request from the VLR/SGSN,generates the SQN and RAND, calculates the authentication vectors (MAC,
XRES, CK, IK, and AK), and sends them to the VLR/SGSN.
Among the authentication vectors generated by the HLR/AuC, the MAC is used
to enable the MS to verify the legality of the network; the XRES is used to enable
the network to verify the legality of the MS; the CK and the IK are used toencrypt the air interface and verify the integrity of the authentication data; the AK
is used to encrypt the SQN.
The role of the SQN is to ensure the freshness of the authentication vectorbetween the MS and the VLR/SGSN. The authentication before every
communication adopts different authentication vector to ensure that the CK and
IK adopted in every communication event are calculated based on differentRAND. The MAC used in every authentication uses the incremental SQN as one
of its input variables to ensure the freshness of the key and prevent attacks. The
AMF participates in the calculation of authentication vector as a parameter. Everyvendor adopts a default value for it. The AMF of Huawei's HLR is set to 0x762C.
3. The VLR/SGSN receives the authentication vectors, sends RAND||AUTN to theMS, and requests the MS to generate authentication data and verify SQN.
4. The MS receives the authentication request. It calculates the XMAC, and thencompares the XMAC with the MAC of the AUTN. If they are different, it sends a
refuse authentication message to the VLR, and gives up the authenticationprocess.
5. The MS verifies whether the received SQN falls within the valid range. If not, the
MS sends a synchronization failure message to the VLR, and gives up the
authentication process.

When the VLR initiates the data recovery flow request, the HLR reinserts the
data of the subscriber to ensure the subscriber data consistency between the VLR
and the HLR.
Enhancement
In the data insertion flow, the HLR9820 supports sending replacement data if the VLRdoes not support the original data. When the VLR does not support the service data
sent by the HLR, the HLR sends the replacement data according to the relatedconfiguration. For example, when the HLR sends ODB-BAOC, the VLR returns a
response to indicate that it does not support the data. In this case, the HLR rejects the
configuration data or sends supplementary service BAOC, depending on the relatedconfiguration data.
