What is SMS Home Routing and How Does it Work

SMS home routing is a game-changer for businesses and organizations that rely on SMS communication to reach their customers. It allows them to send and receive SMS messages through their own phone numbers, rather than using a third-party short code.

This means that customers can receive messages from a familiar number, increasing the likelihood of them engaging with the content. SMS home routing also provides businesses with more control over their SMS communications, allowing them to personalize and automate their messaging.

By routing SMS messages through their own phone numbers, businesses can avoid the costs and limitations associated with using short codes. They can also use advanced features like two-way messaging and analytics to gain insights into customer behavior.

The inconsistency in the original GSM specifications led to a major problem with SMS. The specifications allowed inbound messages to bypass the home network, instead being sent directly to the target handset.

This put SMS out of step with other forms of communication like voice telephony, email, and MMS, which all have the home entity responsible for managing both inbound and outbound traffic.

The original GSM specifications were designed with voicemail alert systems in mind, not person-to-person messaging. This outdated approach prevented operators from generating new revenue by offering value-added SMS services.

In 2006, UK mobile operator Vodafone highlighted this issue, pointing out that a large percentage of SMS traffic was outside the direct control of the receiving network.

The Home Solution is a game-changer for SMS routing.

Home Routing uses the recipient network's Home Location Register (HLR) to change the flow of inbound off-net messages, directing them to an SMS router.

This allows advanced services like divert, copy, and archiving to be applied before messages are delivered.

The 3GPP standardized two forms of SMS Home Routing: Non-Transparent Home Routing and Transparent Home Routing.

Non-Transparent Home Routing supports all types of advanced SMS services.

Transparent Home Routing, on the other hand, only supports a limited subset of advanced SMS services and the issuance of delivery receipts.

This is due to lobbying from bulk SMS service providers.

Security is a top concern in the SMS delivery process. External networks can send queries for subscriber locations and identities, which poses a security risk.

These queries can be used to launch various attacks, including location tracking, eavesdropping, DoS, and SMS spamming.

The SMS Home Routing process provides a solution to this issue by never disclosing real subscriber locations or identities.

To set up SMS home routing, you'll need to obtain approval from your carrier, as required by the FCC's rules on wireless roaming.

Compliance is key, and failure to obtain approval can result in fines and penalties.

Cellusys provides SMS Home Routing according to the 3GPP TR 23.840 standard, which was originally released in 2006 and updated to version 7.1.0 in 2007.

The 3GPP is a standards organization that develops specifications for third-generation mobile networks, closely linked with GSMA. They provide several industry standards and studies.

Cellusys supports TCAP Handshaking on MT submission, a key feature for improving inter-PLMN architecture functionality and security.

3GPP TS 33.200, released in 2001, defines various security mechanisms necessary for the GSM MAP protocol, with the latest version 7.0.0 released in 2007.

3GPP TS 29.002, released in 1999, details the operations, parameters, and message flows used by the SMS.

An SMS message is a short text or binary message that carries 140 bytes of useful data, which can be 160 GSM characters, 70 Unicode characters, or 140 bytes of binary data.

SMS messages can be long, but they're limited to 160 characters. To get around this, the technology of segmentation and reassembly (SAR) is used, where long text messages are split into multiple SMS messages.

A connection is an interface for an SMS message to come into or go out of a system. This can be an SMPP client connection to a mobile network operator, or even a database connection.

SMS routes take a message from one connection and pass it to another connection. For example, a route can take a message from a database connection and pass it to an SMPP client connection.

An SMS routing table contains a list of routes. This is what the system checks when an SMS message comes in from a connection, trying to match it to the right route.

To route SMS messages, you'll need to follow a series of steps. These include adding a new SMS connection to the mobile network, adding a new SMS user or application, and creating an outbound and inbound SMS route.

Here's a quick rundown of the steps involved in routing SMS messages:

Defining a phone number prefix for routing allows you to select which service provider connection to send a message to based on the prefix of the recipient's phone number.

The SMS Home Router is incredibly versatile, and one of its key features is its ability to be deployed standalone or as part of a larger system.

You can choose to deploy the SMS Home Router independently, or you can complement it with additional protocols as modules of the Protect Unified Signalling Firewall as needed in the future.

The SMS Home Router uses REST API integration, which is a game-changer for seamless communication and flexibility.

This integration makes it easy to work with the SMS Home Router, and it's a key factor in its ability to support virtual deployment or installation on customised servers.

Sms Home Routing is a feature that allows you to redirect inbound messages to an SMS router, applying advanced services like divert, copy, archiving, and anti-spam before delivery.

This feature was standardized by the 3GPP in two forms: Non-Transparent Home Routing, which supports all types of advanced SMS services, and Transparent Home Routing, which supports a limited subset of advanced SMS services and delivery receipts.

Home Routing uses the recipient network's Home Location Register (HLR) to change the flow of inbound off-net messages, directing them to an SMS router.

To implement Home Routing, you'll need to set up two routing rules, where the From connection is the user sending the message and the To connection is the two service providers you want to send the SMS to.

Here's a simplified overview of the steps involved in setting up Home Routing:

By implementing Home Routing, you can apply advanced services to inbound messages, making it a powerful tool for managing SMS communications.

Customization is a key aspect of SMS home routing. You can define a phone number prefix for routing in the SMS Gateway, which allows you to select a service provider connection based on the prefix of the recipient's phone number.

To do this, you can enter the phone number prefix in the To address field on the Match tab. This is a crucial step in ensuring that your messages are routed correctly.

You also have the option to modify the SMS message text during routing. This can be done in the Replace message Text field on the modify tab of the routing rule.
