SMS Home Router
SMS Home Routing is an essential security component of any mobile network which centralises all SMS traffic to a common routing point in the home network.
Unified or Independent
External networks send queries for subscriber locations and identities in the SMS delivery process. Providing this information to external networks poses a security risk as it can be used to launch a multitude of SS7 based attacks including location tracking, eavesdropping, DoS, and SMS spamming.
The SMS Home Routing process permits the delivery of SMS by external networks while never disclosing real subscriber locations or identities.
Signalling Providers and Signalling Hubs
Signalling is your business — at least make it secure. We have provided many Tier 1 signalling hubs with the capability to control and secure their signalling.
Cellusys provides SMS Home Routing according to the 3GPP TR 23.840 standard. It supports TCAP Handshaking on MT submission, and is 3GPP TS 33.200 compliant.
3GPP is a standards organization originally assembled with a goal of developing specifications for third generation (3G) mobile networks. Closely linked with GSMA they provide several industry standards and studies.
3GPP TR 23.840 originally released in 2006 has been updated with the latest version 7.1.0 released in 2007. It outlines how inter-PLMN architecture can be improved in terms of functionality as well as security.
3GPP TS 33.200 was released in 2001 and updated regularly with the latest version 7.0.0 released in 2007. This specification defines various security mechanisms necessary for the GSM MAP protocol.
3GPP TS 29.002 was released in 1999 and updated regularly with each new overall 3GPP release. This document details the operations, parameters and message flows used by the SMS.
