BSNL Improvement of CCR 1

Improvement of CCR BSNL 2

Improvement of CCR BSNL Definition of CCR : q It is the ratio of Completed call and processed calls by the exchange 3

Improvement of CCR BSNL Completed calls : q. Only answered calls or q. Answered + busy + NR calls 4

Improvement of CCR BSNL Successful calls : q If Only answered calls are considered CCR will be low, where network has nothing to do. q If Answered + busy + NR calls are considered as effective, CCR will be better. 5

Improvement of CCR BSNL DOT / BSNL order : q Only answered calls are to be considered for calculation of CCR. 6

BSNL 7

Improvement of CCR BSNL Target set by HQ q Junction Call = 61. 64 q. STD call = 56. 07 8

Improvement of CCR BSNL q Network congestion q Checking of Routing / Analysis q Alternate Routing q Signaling traffic overload q Setting of MIN-MAX value q CCS 7 en-block signaling q. Use of voice mail 9

Improvement of CCR BSNL q Implementation of CCBS/CCNR q SMS alert in case of No-reply or Busy q Announcement in case of busy subscriber on CW q Implementation of parallel ringing q Proper announcement to educate the calling party about the status of called party q Network failure q Rack Loading q. Proper Co-ordination with TX wing 10

Improvement of CCR BSNL 11

Improvement of CCR BSNL q Regular monitoring of Junction status q Regular monitoring of Junction Occupancy q Immediate augmentation if Occupancy >0. 7 q Route Diversity q Use of NMS 12

Improvement of CCR BSNL 13

Improvement of CCR BSNL q. Periodic checking of exchange database q. Checking with respect to Routing q. Checking with respect to Charging q. Checking with respect to MIN-MAX q. Implementation of En-block Signaling in local network q. Checking of proper over-flow of traffic q. Checking of no-Loop in the network q. Avoid unnecessary transit of Calls 14

Improvement of CCR BSNL 15

Improvement of CCR BSNL q Alternate Routing should not create any LOOP q If traffic in alternate path is very less, 50: 50 traffic should be given for proper utilization q ACD should have same characteristics with respect to original ACH q Avoid giving too many alternate Path q. Use GMSC in case of PSTN to CMTS / UASO 16

Improvement of CCR BSNL 17

Improvement of CCR BSNL q Normally two COCs are created against each TG q Due to Mobile and IN signaling traffic is increasing q COC needs to be augmented based on traffic particularly on POIs q Signaling traffic is further increasing due to VAS services q Splitting of TG in case of > 1000 CIC 18

Improvement of CCR BSNL 19

Improvement of CCR BSNL q. Always use fixed numbering scheme q Always try to keep MIN=MAX to reduce unnecessary holding time i. e. use closed numbering scheme wherever possible q For this Create More ACH on same TG 20

BSNL 21

Improvement of CCR BSNL q In CCS 7 IAM, full address should go q Hence no SAM q Reduced holding time q CCR Improves 22

BSNL 23

Improvement of CCR BSNL q Use of Voice Mail will definitely help to increase CCR in case of Busy and No-reply q Our switches are not having in-built Voice Mail q We can go for revenue sharing model q Call forwarding to AMS on No-Reply condition by default from switch 24

BSNL 25

Improvement of CCR BSNL q SMS can be sent to called party having mobile, if his PSTN is NR or Busy. q Subscriber activate call transfer to voice mail q Voice Mail system will send SMS to a pre-defined mobile number q Call forwarding charge should be waived from the “B” number q Call forwarding on “No Reply” should be given by default 26

BSNL 27

Improvement of CCR BSNL q Announcement to the caller in case of busy subscriber. q Caller will get announcement for 30 second q After 30 second announcement will change and request to caller to try after sometime. q Increase BSNL visibility and CCR also. 28

BSNL 29

Improvement of CCR BSNL q Parallel ring will increase both CCR and revenue. q Access code : 12268 q Available in EWSD technology q Should be available in all NT exchanges 30

Improvement of CCR BSNL 31

Improvement of CCR BSNL Proper announcement to be given to educate the calling party about the status of called party to avoid unnecessary call attempt. 32

BSNL 33

Improvement of CCR BSNL q In case of RLU / Main exchange failure proper announcement to be given to avoid unnecessary call attempt at the originating end on the specified level. q Artificial traffic in the network will affect CCR 34

BSNL 35

Improvement of CCR BSNL q Very high call attempt q Termination is only on single DEL q Very high rejection q CSN rack problem q Very poor CCR q Always give lines on PRI 36

BSNL 37

Improvement of CCR BSNL q CSN wise traffic to be checked q Based on traffic, re-arrangement to be done q Particularly call center numbers to be monitored 38

BSNL 39

Improvement of CCR BSNL q Call centers are taking connectivity on PRI q Very high traffic on said PRI q Preferable to give connection from SMT instead TAN 3 G q Traffic monitoring on all call Centers is a must 40

BSNL 41

BSNL Inter-connect Traffic : q POIs having connectivity with CMTS is carrying roaming traffic q High increase in Roaming traffic q High increase in SMS traffic q PUPE overloading 42

BSNL SOLUTION : q Increase more COC with Private CMTS q Re-distribution of PUPE 43
