Sockets + APNs or UDP

2 replies [Last post]
Anonymous

Does anyone have any resources to show which operators and which of their
APNs support socket based communication rather than just HTTP?

I know in general that you need an Internet APN rather than a WAP APN - is
that always true?

Also, are UDP connections over the various APNs better supported than
sockets?

Basically I'm trying figure which is the best, in terms of speed of
communication and support amongst handsets that are set up as sold to the
general public.

cheers

Most "internet" APNs I've encountered support sockets. UDP should work in
theory, but in practise most likely only works inside the operators
network.

Hi,

I'm by no means a network specialist, but what I have seen is:

1) Connection through a Wap gateway (using WAP APN) is generally much
slower.
2) WAP gateways usually have limitations on the type and size of data
which can be downloaded through them, as many will try to download the
data first and then send it to the requestor. For example, in many
carriers it's impossible to have a Java application which uses WAP APN
to download a file over 500KB in size.
3) I have never tested sockets or UDP connections over WAP APN, but I
suspect that most carriers block them, so you are probably better off
using an Internet APN.
4) WAP APNs connections are normally proxied, so operators can insert
some parameters in headers, such as phone number, that your backend
system would find useful for some use cases, such as authentication,
identification, software licensing (one install per phone number), etc.
