Header Enrichment

HTTP Header Enrichment is a mobile-network capability to authenticate/identify a msisdn,who is browsing thru the internet using mobile network.

It can be used to identify a mobile subscriber based on HTTP request.The process consists of adding data fields in the HTTP header.
Event based:This type of HTTP request is ususally triggered in the background by some of app running on the device in response to an event
for example :User clicking on some button,where the mobile sends various information which the mobile network can use ti identify/authenticate wther msisdn user belongs to thier mobile network or no.So in this way molbile operator knows which user connects to thier network.
The mobile operator whitelists certain urls in which a user hits the url then the request is sent.And this request is then routed to mobile core network ,who identifies the msisdn.
To give internet access to that specific phone, mobile operator will assign IP to the device.THe operator maintains this mapping IP/Deivce.
After identification/authentication,the mobile network ***enriches***(adds header information consisting of phone nnumber from looking at thier mapping table), the request with specific information about the msisdn user that enables a third part to determine the identity of msisdn user.
THe headers used by different mobile networks can be different and upto them.
