SS7

The SS7 signalling product is also known as SS7, SCCP, SIGTRAN, or simply “signalling”.

SS7 enables mobile operators 2G and 3G devices to register to the network and roam internationally, as well as to transport SMS-MMS messages internationally. This service can be offered without IPX connectivity.

Signalling is the information exchange on a network enabling the establishment and control of calls, control of mobility management and security/authentication of the subscriber.

When mobile users travel to a foreign country and switch on their mobile device, the mobile phone will “register” to one of the local mobile networks. This registration process requires ensuring the SIM card is a valid one and establishing what services the users is entitled to: an interaction with the home network is required.

PCCW Global SS7 signalling solution ensures the visited and home network can exchange signalling, ensuring the subscriber can use roaming services while abroad.

 

There are several options for an MNO to connect to the PCCW Global SS7 signalling solution:

  • TDM (E1)
  • SIGTRAN (SS7 over IP) over: 
    • an IPSEC connection (not recommended)
    • a MPLS connection to our IPX platform

Given PCCW Global MPLS footprint, the latter option is highly recommended:

PCCW Global SS7 signalling solution offers all security requirements to ensure the MNO’s network will not be polluted by undesired SS7 messages: GT filtering and screening.

The SS7 signalling solution also comes with an online reporting tool where customers can validate and view the received/sent traffic from/to PCCW Global.
