VoLGA Forum Updates VoLTE Specs

Jul 12, 2010, 7:29 AM by Eric M. Zeman

The VoLGA Forum today announced that it has added several new capabilities to the voice over Long Term Evolution (VoLTE) specification. The new features include the use of VoLGA over HSPA; support for SIM-less emergency calling; optimized voice-bearer routing; and host APIs for LTE handsets. LTE, which AT&T, Verizon Wireless and others are looking to deploy as their fourth generation wireless networks, does not have a native capacity to carry voice traffic. Earlier this year, the GSMA proposed a different solution, called Once Voice. It has the support of 40 different companies, including AT&T and Verizon Wireless, as well as handset makers Huawei, LG, Motorola, Nokia, Samsung, and Sony Ericsson. The 3GPP is working on its own competing standard as well, called CSFB, or Circuit Switched Fallback. CSFB would allow devices to revert to GSM or UMTS for incoming and outgoing voice calls. The GSMA's move to back One Voice gives it an edge over the competing standards. None has been formally agreed upon for use in handsets.

CSFB?

Is that really a standard? It's really just doing nothing except continue using the same voice technology they're using now.

That is exactly the thought that came to my mind when I read the article... there is no benefit at all to CSFB! I am glad the GSMA is supporting something other than CSFB, but I will do more research on this "One Voice" (I think "Once Voice" is a typ...
