4G Messaging

What’s currently happening in the industry?

To meet the ever-increasing demand for data on the go, Mobile Operators are launching 4G radio networks with the ultimate goal of providing all voice and data services over IP. However, the  transition to a globally available, true 4G (all-IP) network will be a long one.

Despite all the hype about OTT messaging, SMS will play a vital role in this transitionary period due to several factors:

fragmentation in the OTT market;

delays rolling out RCS;

the 2G cool spots in-between 4G hotspots;

prohibitive data roaming charges;

mismatched LTE bands;

the long tail of subscribers and networks that are neither 3G nor 4G enabled.

So even operators who blaze a trail into VoLTE, IMS and RCS still need to maintain interoperability with SMS in their own and other networks.

The Challenges

Circuit-Switched Fallback (CSFB) can enable direct interoperability of SMS between LTE and Circuit- Switched (CS) networks but is a stop-gap approach for GSM operators only. Without the benefit of CSFB, CDMA operators are driving the rollout of IMS for VoLTE. Keeping pace with these  developments and launching interoperable RCS is prompting some GSM operators to accelerate their launch of IMS.

3GPP has specified the IP-SM Gateway to support the interoperability of messaging between CS and IMS networks, but that solution may require the operator to invest budget in the CS network when they would rather spend it on 4G technology.

How Jinny can help

Jinny provides two solutions to Operators who want to extend the reach of IMS messaging services to the millions of subscribers who continue to use SMS on circuit-switched networks:

IP-SM Gateway:

A standards-based gateway that provides interworking between IMS messaging services and the SMSC of a GSM or CDMA network.

4G Message Centre:

A fully functional SMSC which includes the interworking functionality of an IP-SM Gateway and provides several cost saving benefits
