Multimedia Messaging Service Center (MMSC)
What is a Multimedia Messaging Service Center?
An MMSC, or Multimedia Messaging Service Center, helps mobile devices share media over wireless networks. MMSCs receive, store, and forward multimedia messaging services (MMS) texts.
How does an MMSC work?
An MMSC works just like an SMSC, but for multimedia messages. When a user sends photos, videos, gifs, or hyperlinks, that message must be relayed to an MMSC before it can reach your intended recipient. Once your phone carrier forwards media to your MMSC, your media is sent to the recipients’ MMSC for forwarding.
The Benefits of an MMCS?
While there are reasons why A2P senders would prefer not to use MMSC or MM4 to send multimedia messages, these are some of the features of MMSC:
- Supports multimedia content
Unlike SMS which is limited to text, MMSC enables the delivery of rich multimedia content such as images, audio, video, and formatted text. - Interoperability
MMSC ensures that multimedia messages can be sent between different carriers and device types, maintaining compatibility across networks. - Store and forward capability
If the recipient is unavailable or offline, the MMSC stores the message and forwards it once the recipient becomes reachable, ensuring message delivery. - Message conversion
It can convert messages to compatible formats if the recipient’s device doesn’t support certain multimedia types, helping to maintain message integrity. - Delivery reports and notifications
Provides feedback to the sender about message delivery status, including successful delivery, pending status, or failures. - Charging and billing integration
MMSCs are often integrated with billing systems to enable proper charging for multimedia message services. - Security and filtering
MMSC can include security features like virus scanning and content filtering to prevent the distribution of harmful or inappropriate content. - Efficient network resource use
By managing message storage and delivery intelligently, MMSC helps optimize the use of network resources and reduces unnecessary data retransmissions. - Supports value-added services
Enables carriers to offer additional services such as marketing campaigns, alerts with multimedia content, and interactive messaging.
How MMSCs work with APNs
- The MMS APN (access point name) serves as a dedicated access point that routes MMS data traffic securely and efficiently between mobile devices and the MMSC.
- This separation from general internet APNs permits better control over MMS service delivery, billing, and network management.
- The MMSC depends on receiving user traffic directed via this MMS-specific APN to function correctly.
How MMSCs work with Bandwidth
Carriers like Bandwidth provide messaging services that connect the organization to Multimedia Messaging Service Centers. All messages powered by Bandwidth that are MMS go through at least one MMSC to reach the recipient.
Bandwidth’s MMSC (BMMSC) is an operator-grade platform that enables multiple service providers to exchange MMS messages with consumers.
When the sender and the recipient have different MMSCs, Bandwidth uses the MM4 protocol to exchange messages between two MMSCs.
BMMSC offers a unique set of value-added services and capabilities that enable operators to deploy MMS quickly and efficiently. Some benefits of Bandwidth’s messaging platforms as a whole include:
- Network Operations Center (NOC) and 24/7 customer support
- Management of all network connections, architecture, and connectivity
- Single point of connection to reach multiple operators/service providers
- Maintenance of operator profiles of supported content types and sizes, as well as any other operator capabilities and limitations
- Incorporation of a wide variety of anti-SPAM and anti-abuse methods to ensure the integrity of the inter-operator MMS traffic
