Integration with WTL (Wireless Technology Labs)

PortaBilling is integrated with WTL (Wireless Technology Labs) mobile core infrastructure. WTL specializes in providing mobile core and small cell solutions for MVNOs. With this integration, mobile operators using WTL solutions can streamline the provisioning of subscriber data into the mobile network and enable real-time charging for internet access, voice calls, and SMS services.

The subscriber data provisioning to WTL’s HLR/HSS is performed based on PortaOne Workflows. Events such as SIM card assignment, account blocking/termination, or service package changes trigger corresponding updates in WTL’s system via an API. Contact our sales team if you need to provision additional data.

For real-time authorization and charging (AAA), the WTL’s mobile core and PortaBilling communicate via the Diameter protocol. When a user attempts to use a service, PortaBilling authenticates them, and authorizes the internet session, voice call, or SMS to verify that the user has sufficient balance/quota to use the service.

MVNOs/MVNEs can launch services using WTL’s flexible solutions.

1. Contact the support team for assistance with provisioning configuration.
2. On the PortaBilling web interface, configure the nodes for internet access and voice calls/SMS.
   1. For internet access, WTL Packet Data Network Gateway (P-GW) communicates with PortaBilling via the Diameter Gy interface.

      To configure P-GW as a node, fill in the details:

      • Manufacturer – select “PortaOne”
      • Type – select “Generic”
      • Node ID – specify the “host” value identifying the WTL’s P-GW (on the MNO’s side it’s specified in the Origin-Host AVP, e.g., node.company.com).
      • Turn on the toggle Enable communication with billing
      • Client protocol – select Diameter
      • Realm – specify the “realm” value identifying the WTL’s P-GW (on the MNO’s side it’s the Origin-Realm value, e.g., company.com)

        

   2. For voice calls and SMS, WTL service control point (SCP) communicates with PortaBilling via the Diameter Ro interface.

      To configure WTL’s SCP as a node, fill in the details:

      • Manufacturer – select “PortaOne”
      • Type – select “Generic”
      • Node ID – specify the “host” value identifying the WTL’s SCP (on the MNO’s side it’s specified in the Origin-Host AVP, e.g., scp.company.com).
      • Turn on the toggle Enable communication with billing
      • Client protocol – select Diameter
      • Realm – specify the “realm” value identifying the WTL’s SCP (on the MNO’s side it’s the Origin-Realm value, e.g., company.com)
