NowWAP, Radius Accounting and MSISDN headers
NowWAP was recently updated over the summer months to address an issue on heavily loaded systems where Radius packets could be lost. NowWAP uses these Radius accounting packets in order to determine the identity (phone number or MSISDN) associated with the device that is making a request. NowWAP includes the phone number in an X-MSISDN header when forwarding the request to a downstream content...

What is an MMS postcard? MMS Postcard is a name for a collection of person-to-service/application services where multimedia...
Read MoreMMS MM7 SOAP Problems with Vodafone UK
If you’re trying to use NowSMS to interface with the Vodafone UK MMSC over MM7, you may be experiencing a problem where the Vodafone MMSC is reporting SOAP errors, indicating that the SOAP headers cannot be accessed. This appears to be a bug in their MMSC. The Vodafone UK MMSC does not like the MIME boundary text that NowSMS generates. While the MIME boundary used by NowSMS correctly...
Read MoreMMS Message Retries, Expiration, Conversion to SMS
There was a good simple question posted on the NowSMS Discussion Board. We are using the MMS Gateway service. For how long does the MMS contentstays in the system?Can we set a specific time for the message expiration?We also use the option of converting the mms to SMS with web link. Forhow long is the content stored in the platform? As I replied to that question, I realized that there are a...
Read MoreOne WAP Gateway for both MMS and Browser Data
Smaller mobile operators often ask us how to deploy a single WAP Gateway (or WAP Proxy if you prefer that terminology, as our marketing folks seem to prefer) to deploy both MMS traffic and general browser traffic. Of course, technically there is no reason that a single WAP Gateway can’t support both types of traffic. So if you’re not a mobile operator, you’re probably wondering...
Read MoreMigrating to a Multiple Server MMSC, WAP Gateway, or NowSMS Gateway
The recent postings about multiple server redundant NowSMS or NowWAP configurations have generated a lot of questions from existing customers about how to migrate an existing installation to a multiple server configuration. Migrating an existing NowWAP installation to a multiple server configuration is the easiest task to explain. That’s because there is no shared data storage requirement,...
Read MoreMMSC MM4 Interconnection Basics
MM4 is the standard protocol that is defined for connecting together two or more MMSCs. MM4 is an SMTP based protocol, meaning that the MM4 protocol defines how MMS messages are encapsulated for delivery over the SMTP protocol. In NowSMS, to define an MM4 interconnection, it is necessary to define two components. The outbound connection to the other MMSC is defined under “MMSC...
Read MoreMMS Message-ID Length problems with some handsets and/or MM4
We received a report from a customer that was experiencing a problem where some Nokia handsets would restart themselves after sending an MMS message. The MMS message would be sent ok, but the sending handset would restart after a confirmation is displayed that the MMS message had been sent. This problem was caused because the length of the MMS message-id generated by the NowSMS MMSC was longer...
Read MoreMobile Number Portability (MNP) and the NowSMS MMSC
The NowSMS MMSC implements a dynamic MMS routing callback facility for environments where more advanced MMS routing capabilities are required. The standard NowSMS MMSC configuration allows for MMS routing based upon phone number prefixes. However, in MNP environments, it may be necessary to query a database to determine how to properly route an MMS message. Dynamic MMS routing callbacks also...
Read MoreMultiple Modems for Sending Outbound MMS
File this as a “not so obvious” configuration feature of NowSMS…. When you are sending MMS messages via an operator MMSC using a GRPS(/EDGE/UMTS/WCDMA) modem, NowSMS only allows you to designate one of the modems as the “Default Route” for outbound MMS message routing. So, if you have multiple modems installed, all messages are sent via only one of the modems, unless...
Read MoreSmall Image Size in Received MMS
A recent posting on our disucssion board got me thinking. The question was asking about how when the customer receives inbound MMS messages via a modem, the images are being scaled down to a thumbnail size. I don’t have a clear-cut answer on how to resolve the situation, because it tends to be a mobile operator specific issue. But I thought my explanation of why it would happen, and how you...
Read MoreReceiving MMS Messages Over a GPRS Modem – MMSINQ and MMSCDATA Directories
If you’re configuring NowSMS to send and/or receive MMS messages using a GSM/GPRS (or EDGE/UMTS/WCDMA) modem, the initial setup can be a little confusing. It’s confusing because NowSMS is like a swiss-army knife of SMS and MMS messaging functionality. We’ve tried to make NowSMS easy-to-use for accomplishing basic messaging tasks … but a big part of the appeal of NowSMS is...
Read MoreMMS Virus Blocking
Various public reports have discussed the potential for viruses to be spread via MMS. To date, most of the identified viruses have targeted Nokia Series 60 (and potentially other Symbian) phones. NowSMS v5.51b – March 2005 In March 2005, NowSMS v5.51b was released, which included a configuration option intended to help prevent the spread of viruses via MMS when NowSMS is used as the MMSC. The...
Read MoreUsing NowSMS as an MMSC in CDMA or CDMA2000 Environments
Delivering MMSC functionality in an CDMA or CDMA2000 environment can be challenging because the original WAP specifications for CDMA have technical requirements that require additional SMSC functionality. (Technical note: CDMA2000 is different from WCDMA. CDMA2000 is an evolutionary upgrade path from CDMA. By contrast, WCDMA is an evolutionary upgrade from GSM/GPRS. CDMA2000 builds upon...
Read MoreNowSMS Operator MMSC Considerations
The primary considerations for the NowSMS MMSC in an operator environment pertain to user provisioning and user identification. In the standard configuration for the MMSC, it is a requirement that each user be configured with a special MMS Message Server URL. The URL contains the username and password of the user account on the MMSC. In an operator environment, it is not practical to provision...
Read MoreRouting MMS Notifications via a WAP Push Proxy Gateway
By default, the NowSMS MMSC expects to be able to send MMS Notification via its built-in WAP Push Proxy Gateway (PPG), which delivers MMS Notifcations using WAP Push over SMS. For GSM/UMTS/WCDMA environments, NowSMS automatically generates UDH (user data header) in the SMS messages. For CDMA/CDMA2000 environments, the NowSMS SMPP implementation supports WDP Adaptation so that MMS...
