4 Services and Functions

C&C08 SHLR9200

Product Description


4.1 Mixed Number Allocation in PSTN

In the PSTN, the SHLR is connected to all the local call-originating switches. Thecall-originating switches in the local PSTN comprise:

TS Gateway MS LS SSPThe users can configure data on these local switches to decide whether all calls originated

from local exchanges are sent to the SHLR for authentication before they are connected. If theLS does not support the SHLR, the MS must support it.

The mixed number allocation service allows unified management of subscriber numbers in

the coverage area of the SHLR.

The subscriber provided with the mixed number allocation service has two numbers: DN and

LRN. If the subscriber moves to another residence, only the LRN is changed, and the DN maynot be changed. The number portability (NP) is thus realized for terminal subscribers.

4.2 IN ServicesThe SHLR stores the IN service subscription info of subscribers. All the local call requests

(from PSTN subscribers and NGN subscribers) are sent to the SHLR. The SHLR queries thesubscription info of the subscriber and then returns the IN service access code. Based on theIN service access code, the LS connects the call to the SSP. The SSP then triggers the IN

service.

4.3 Disaster Tolerance

As the central database, the SHLR processes and backs up the subscriber data. When theactive SHLR is not available, the signaling system Number 7 (SS7) and other functionalentities can exchange signaling. The redundancy SHLR can also work as the active SHLR

temporarily.

The SHLR provides two disaster tolerance solutions:

1+1 Load-Sharing Redundancy Solution N+1 Mated Redundancy Solution


23/48

C&C08 SHLR9200

Product Description 4 Services and Functions


1+1 Load-Sharing Redundancy Solution

In this solution, two SHLRs work in mutual backup mode. That is, either of the two SHLRs

shares 50% of the work load.

Each SHLR stores the static data of all subscribers.

If one SHLR fails, the other SHLR takes over all the service processing.

N+1 Mated Redundancy Solution

In this solution, several SHLRs work as the active SHLRs, and one SHLR works as the

redundancy SHLR. The active and redundancy SHLRs store the static data of all subscribers.

The redundancy SHLR backs up the data of the active SHLRs to ensure data consistency.

If an active SHLR fails, the redundancy SHLR takes over the service processing of the faulty

SHLR. The services can be manually or automatically switched over.

The SHLR supports N+1 SHLR static data backup based on the BOSS system. The baseline

data is backed up in cutover manner, and the incremental data is backed up in the BOSSoperating system. The existing SHLRs in the network need not be upgraded.

NOTE Performance level A: The system can endure the test load imposed on it without being damaged, and

can work normally in the specified conditions. The software or data of the tested switching system

(all the data in the memory or being processes) does not change. The system performance is not

affected.

Performance level B: The system can endure the test load imposed on it without being damaged. Thesoftware or memory data does not change. The communication performance is affected. The effect,

however, is within the endurable scope (the scope can be defined according to the product situation),

and the established communication links are not interrupted. The system, after the test, can

automatically restore the normal performance without manual operation.

Performance level C: Some of the functions of the equipment are lost during the test. Thosefunctions, however, can be restored automatically in a certain period of time after the test (usually,

the shortest time needed from the system restart to service ready). No physical damage or system

operation software deterioration occurs.

Performance level R: After the test, no physical damage or fault (including software damage) occurs.Damages of the protective device caused by outside interface signals are allowed. After the

protective device is replaced or the running parameters are reset, the equipment can still work

normally.
