WAP Gateway Blocks BlackBerry App World
It has come to our attention that the default configuration setting for the NowWAP WAP Gateway blocks users from connecting to BlackBerry App World. The reason for this seems to be some unusual communication patterns between the handset and the App World server. The handset attempts to created a tunneled connection to the HTTP port (80) of the BlackBerry App World server. Symptoms of the problem...
Read MoreSMPP Information and Resources
SMPP (Short Message Peer-to-Peer) Protocol is an industry standard protocol that is used for exchanging SMS messages between peer entities.

In simplistic terms, an SMSC manages SMS messages for a mobile operator network, delivering SMS messages to mobile...
Read MoreSMPP Asynchronous Mode
One of the biggest limitations to SMPP performance is protocol implementations that do not support SMPP asynchronous mode, or to state it more correctly, do not take advantage of the speed boost that is possible with SMPP asynchrnous mode. SMPP Synchronous Mode = One Message at a Time In SMPP Synchrnous mode, each side of the SMPP client has only one outstanding transaction active at a time. ...

Read MoreSMPP Receipt Message ID Tracking Over Multiple Connections
One of the standard capabilities of NowSMS is the automatic mapping of receipt message IDs when routing messages to an upstream SMSC connection. The reasoning/logic is simple. When NowSMS accepts a message from a client, NowSMS needs to assign an ID to the message. When the message gets routed to an upstream SMSC, that SMSC will assign a new message ID. NowSMS saves the message ID assigned by...
Read MoreOperator MMSC Accounting – Detecting Roaming Subscribers
One important consideration when charging for MMS messages is whether or not the user is roaming.

Before the MMSC can pass this information to the accounting callbacks, the MMSC must receive this additional information from the...
Read MoreNowSMS and SSL Certificates – 2048 Bit Key
In the last 6 months, many SSL Certificate Authorities (CAs) have made a switch to requiring web servers to use 2048-bit private keys. It is believed that increased computing power will make the commonly used 1024-bit keys possible to break by 2011. There is a side effect in switching to the larger keys that some old web browsers don’t support > 1024 bit keys. I can’t find a good...
Read MoreMobile Number Portability (MNP) and the NowSMS MMSC
When the NowSMS MMSC is used in environments with mobile number portability (MNP), the MMSC may need to query a database to determine whether a recipient is local to this MMSC or if it belongs to another operator. The interface to support this is defined in the following article: Mobile Number Portability (MNP) and the NowSMS MMSC However, there is an additional issue that is not discussed in...
