Introduction

Worlds first commercial 3G network was

launchedbyNTTDoCoMo in Japanback in

2001.Since then,3Goperatorsaround the

globehavebeenstruggling tocapitalizeon

theirinvestmenton3G.Sincetheinception

of 3G networks, operators focused on 2

areasforrevenuegenerationfromtheir3G

networks,

1.Mobilebroadband

2.Videocalling.

Video calling was a highly anticipated

feature in the 3G networks. However,

operators were left with wondering as to

whyvideocallingisnotcontributingenough

revenueasexpected.Therefore,oneofthe

biggest challenges for a 3G operator is to

improve the p2p video calling revenue on

their3Gnetwork.

ChallengesinP2PVideoCalling

Itisimperativethatanycalloriginatedona

network,regardlessofwhether itsvoiceor

a video call, need to be completed. The

most straightforward and simplest way to

makethis

happen

is

to

answer

every

call

received by the B party. This was really

difficult in thecaseof3Gnetworksdue to

followingreasons,

1. Receiverhandset not supporting 3Gorvideocalling

2. Receiveroutof3Gcoveragearea3. Poor3Gcoverage4. Interconnection problems between 3G

operators,bothlocalandforeign

In the history of telephony several call

1. Answeringmachines2. VoicemailPlatforms3. MissedCallnotificationServices.Videomailalone,isitenough?

With the adventof3Gvideo calling, video

dimensionwas added to voicemail;hence,

videomail is introduced.However, the fate

ofthevideomailwassimilartovoicemailas

it isnotapopularservice insomepartsof

the world such as Asia. Also, failure of

videomailwasattributedtoanotherreason;

reason,videocallsjust failed.This resulted

in,

1. Dissatisfaction due to incompletevideo calls. Sometimes, it couldbe the

2. Poor perception on video calling customer loses confidence on video

3. Revenue lossOperator loses revenueasthecallsarenotcompleted.

Lots of market researches done by the

operatorsandexpertsonthedomainreveal

that, forvideocallingtobesucceeded ina

3Gnetwork it isessential to complete the

video

call

in

a

more

effective

way

than

just

atavideomailbox.

It is important to identify the composition

intypicalnetwork,

Aspertheabove,initially,3Gpenetrationis

low. Therefore, in a typical network there

wouldbemore2.XGhandsetowners than

3G users. This results in lots of 3G video

callsfailing.

Anidealsolutiontofailedvideocallswould

be to complete them as voice calls.

Whenever a video caller tries to make a

video call and if it fails, for, B party not

Avideocallcanbecompletedtoavoicecall

inthefollowingmanner;

Typically, when a video call fails, network

identifies it.Then itcouldtakeanactionto

complete it as a voice call.Before the call

completion decision is taken network

shouldideally,

1. Informthevideocaller,or2. Take the permission from the video

caller,

tomake a fall back on to voice.Once the

decision is taken, network will initiate a

second audio leg to B party and upon

successful answer, both the legs will be

patched up together. The calling party leg

will be video while the called party leg

and

capability to handle the media conversion

Littlebitofadvertising

Sinceusers

generally

make

video

calls

expecting some form of audio visual

experience, it is important to fill this gap.

This space can be utilized as an

infotainment or advertising space which

couldpotentiallybringmorerevenuetothe

operator. From the callers point of view,

when thevideocall is fallenback tovoice,

he/she could easily verify the reason by

talkingto

the

other

party.

Thus,

customer

is

not frustrated with a failed video call.

Specially, this is a very effective and a

simple solution. Voice call completion

happens seamlessly without any

interruptions.Callerisjustnotified.

It is difficult to find this type of complete

video call completion solutions deployed

with correct mix among the operators.

Often it is found that Videomail or Video

SMS

is

deployed

but

never

completion solutions are not common in

the market due to the complexity of

video/audio networking and call charging

issues.
