HTTP Interface for Cell Broadcast Service - Introduction

This section is only applicable to lab applications and the test application with a required feature license.

This section explains HTTP interface for configuring and sending cell broadcast messages. You can use the HTTP interface to interface with custom programs. You can also use the HTTP interface to control the test set's cell broadcast service parameters through the address bar of an internet browser.

HTTP Overview

HTTP is the client/server based protocol used to deliver virtually all files and data on the World Wide Web. If you'd like a more detailed description of HTTP protocol, refer to Internet RFCs `HTTP/1.0 - RFC 1945' and `HTTP/1.1 - RFC 2616', which can be downloaded from

When you use HTTP in a web browser, you enter the "address" for the web page you wish to view. These addresses can be generalized into the following format:

In this example, the web browser is the HTTP client and it uses the information in this address to open a connection to an HTTP server and send a request.

HTTP for Cell Broadcast Messages

The test set acts as a server for cell broadcast messages. If you have a PC and your test set connected to a network or directly connected together, you can open a web browser (client) and send a request to the test set using the test set's IP address and a correctly configured request URL. For example, Once the sets set is configured to allow the use of the HTTP interface and cell broadcast service is enabled in the test set, you might send the following from the web browser if your test set's IP address was

It is not necessary to specify a port number because the test set uses 80, which is the default port for HTTP.


Setting the message 1 state to ON, starting the cell broadcast service, and sending the above URL causes an cell broadcast message to arrive at the mobile station attached to the test set's RF port. This message contains the text "Hello".
