Where ever you hear the name gateway, assume that we are talking about external connectivity. SMS gateway is used to provide SMS connectivity to third parties or solve protocol incompatibilities.
The SMSC is a part of the operators SS7 network. The SMS gateway is connected to the SMSC. In most cases the SMSC has inbuilt gateways. Any external connection from a network other than the SS7 network is handled through the gateway.
One major advantage of a gateway is that it supports TCP/IP based SMPP protocol. So we can access an SMS gateway from an IP network like the internet. Bulk SMS providers setup their own gateways or get connectivity to already set up gateways.
The SMS gateways provides SMS connectivity to third parties via many protocols, which includes HTTP, SMPP and XML. This allows a normal programmer to access SMS services very easily without having to worry about the telephone network protocols. If he is using the HTTP protocol to connect to an SMS gateway, he can send an SMS by calling an http request.
The only limitation of HTTP is that the number of SMS that can be send per second is less than 10. For higher throughput we need to use SMPP protocol. Its a bit more complicated, but many open source libraries are available to make the task easier.

SMPP stands for short message peer to peer protocol. As per the defination, SMS Gateway for acting as an intermediary/gateway between two incompatible networks for sms interchange(between SMSC-in SS7 and other networks). So for communication with the SMSC, extenal applications or SMEs(not in SS7 network) uses SMPP protocol. You can refer to smsforum.com for more information on this.

SMS Gateway:
Used in network operator’s server units for VAS(Value Aided Serves) applications. When a subscriber tries to use some VAS application like, using some operator pre-configured content using some short code(For example PNR to 2222 for getting the PNR status of railway ticket), on getting the request, SMSC will route this MO message to the SMS Gateway. SMS Gateway in turn process this request by sending HTTP(TCP/IP) request to the VAS application available in internet. On getting the response from the VAS application, SMS Gateway processes the HTTP response, removes the un-necessary tags and dispaches the response to the SMSC for the forward delivery of the message as an MT response to the subscriber. This is none as MO-MT pull operation be the mobile user.
configuration route Rrequre ip but1 ip eg:-10.0.0.10 cost per month min 300 rupees then 1 computer internet connection charge p.m min 300 rupees but computer configuration tcp/ip give 1 ip . my question ip charge more but not more isp provider 1 ip charge why?
