How to use HLR lookups in SMS routing
This guide provides information about HLR lookups and how HLR information can be used in SMS routing. It first defines what an HLR is, and proceeds to give information on how HLR information can be used in SMS routing. Finally it gives detailed step by step instructions on how to setup HLR lookups in the Ozeki SMS Gateway.
What is HLR
HLR stands for Home Location Register. HLR is a database maintained by the mobile network operator with a list of phone numbers it originally issued. The HLR stores information about whether a phone number is connected to the moible network, is it ported to a different telephone company and is it roaming a different network.
All mobile network operators are connected within a system called the SS7 signaling network. The SS7 transports data about subscribers, networking, voice calls, and SMS text messages between the carriers. Real-time context and status information about every mobile phone is stored in databases called Home Location Registers, which form the backbone of subscriber information for a mobile network.
HLR Lookups is a technology to query home location registers and acquire live networking and connectivity information about mobile phone numbers, such as, whether a mobile phone is switched on or switched off, to which network it belongs, whether it is currently roaming, if a number has been ported between networks, and if it is valid or invalid.
HLR Lookups supply businesses with real time queries towards the home location registers of all mobile networks. This documentation helps you to implement HLR Lookups into your own software to automatically receive real time mobile phone information when needed.

How are HLR lookups used in SMS routing?
The Home Location Register (HLR) plays an important role in SMS routing, because it can provide information to where the text message should be routed to.
Large companies setup many SMS routes, to various SMS service providers and mobile network operators and they use SMS routing to determine where each text messages should end up. SMS routing selects the appropriate SMS service provider connection, such as an SMPP client protocol connection, a CIMD2 client protocol connection or a UCP sms client protocol connection for sms deliery.
A HLR lookup can provide valuable information on how an SMS messages should be routed. A HLR lookup in Ozeki works by attaching tags to the SMS messages. Tags contain information about the fields returned by the HLR lookup. HLR lookup is performed before SMS routing takes place. When an SMS route is created it can use match conditions of tags to select the approriate SMS service provider connection based on information received from the HLR lookup.
HLR based routing (Video tutorial)
The following video gives you all the information about how you can use the HLR Lookup service to route your SMS messages.

In the HLR Lookups groupbox, you will find a checkbox that is for enabling the usage of the service for SMS routing (Figure 14). Tick in the checkbox and click on the Ok button to finalize your configuration.
Send a test message
You could test the new routing settings by sending a test message to the recorded phone number. This way you will be able to get the tag that the HLR Lookup attaches to the message. To do so, click the New icon on the tollbar of the Ozeki 10 SMS Gateway (Figure 15). Now you will see New message composing panel. In the Address textbox, you will need the phone number, you wish to send the test message to. Under it, you can see the Message input field. Type in the HLR test text and click the Ok button to send the message. This way, the HLR lookup service will search for information about the phone number. It will attach the information to the message.
Check the tags of the sent message
If you have successfully sent the message and it was submitted, it will be visible in the sent folder. To check the information your need in the tags, look for the user information panel on the left side (Figure 16). In the Folders groupbox, you can find the Sent folder. Click it and check the list of sent messages. Under the list, you will find the Message details panel. Here you can see all the information about the submitted message. Look for the Tags tab page next to the Delivery history tab. Click it and you will be presented with the tags that the HLR Looks service attached to the message. Here, you need to find the hlr_original_country_code field. This tells where the phone number is registered originally. Copy that information somewhere for later use.
Add a new route according to the HLR
To have the message delivered successfully, you need to create a route for it according to the information obtained by the HLR service. To do this, open the Route list with the Route icon located on the Toolbar (Figure 17). Now you will find a blue button titled Create new Route. Click it to open the Route details panel on the right side of the screen. There you will find the Settings groupbox. In that groupbox you will find the To input field.

Int his groupbox, you can add a tag name which will be detected and a tag value which will be used as the condition for detection. Next to each input field, there will be a help icon, which can be used as a way to get more information about what you need to type in to the textbox.
In the Tag name groupbox, paste in the hlr_original_country_code text that was copied from the tags of the submitted message. Paste the value of the hlr_original_country_code into this textbox. This way, if the gateway detects that a message is sent with the provided value, it will automatically use this suitable SMPP protocol for sending the SMS. In the example case this is the GB tag (Figure 19).
Send a new test message
Now it is time to send a new test message. Just as before, click the New icon on the Toolbar. This will take you to the New message compositor page. In the Address textbox, you need to provide the phone number you have sent the last test message to. Under it you can see a Message input field. Type in the HLR route test text. Click on the Ok button to send the message.
Test message successfully sent
On the Message delivery history page, you can confirm that now the test massage was sent through the new configured SMS connection. The first test message status said the message is submitted. Now this new configured SMS message status says sSubmit accepted by the receiver. Now you can use this configured SMPP connection to send messages to the country you have provided the code of as a tag value.
