Real-time traffic steering that moves cellular to Wi-Fi networks in the works for mobile users - williamsindesur71

Mobile users can belik look forward to beingness automatically transferred from cellular to Wi-Fi networks in the about future day, but loss backward and forward for the best possible performance is another count.

Software instantly in the works will purpose real-time knowledge about network conditions to make lightning-fast decisions roughly the best scheme for each drug user to be on at a given instant. The estimation is that just because there's a Wi-Fi meshwork nearby, doesn't necessarily mean your smartphone should start using it. If every contributor near that hotspot got switched over to it, the Wi-Fi experience could suffer.

It's already common for Wi-Fi networks in public places to get overloaded at busy times. Automatic handoffs from cellular to Wi-Fi, while convenient, won't wee-wee that situation any better. To prevent those overloads, networks will need more management smarts, said Daryl Schoolar, an analyst at Ovum.

That's why both Ericsson and Nokia Siemens Networks announced technologies at CTIA Wireless last week for supposed real-time dealings steering. But the aggregation of standards that the industry is currently adopting for easy cell-to-Wi-Fi handoffs doesn't yet include this capability, thus it may take a while for carriers to make it available.

Maneuverable operators progressively are giving their subscribers access to Wi-Fi, both by deploying hotspots and by partnering with other providers. This can give the carriers additive capacity, without paying for some other spectrum permission, in areas where many people gather and use changeable devices. For subscribers, it can mean faster network connections, conditional the cellular reportage in the area.

Emerging technologies tin authenticate users and put them on Wi-Fi automatically, eliminating the tasks of finding the network and logging in thereto. However, that process is centered on the mobile twist, which can lead to problems, said Sheila Burpee Duncan, head of Wi-Fi marketing at Ericsson. A call up surgery tablet may be set to automatically go onto Wi-Fi wherever it detects the signal, even though information technology doesn't know whether the Wi-Fi network is overloaded, she said.

Not working together well yet

The two types of networks still are largely independent, a trouble AT&adenylic acid;T is looking to solve, said Kris Rinne, AT&T's old V.P. of network technologies. Her company has one of the largest Wi-Fi deployments of some mobile operator.

"Nowadays, they don't know anything most each some other, and thus you have to premise that," Rinne said in an interview at CTIA. AT&T expects ANDSF (Access Network Discovery and Selection Function), a spec from the 3GPP, which oversees waterborne standards from GSM through LTE, to help it wor the problem.

However, ANDSF isn't designed to make decisions more or less network choice in real time, Ericsson's Duncan said. Or else, it's manageable by overall policies that are designed to equal metamorphic at particular multiplication, such as when a discipline is scheduled to make it at a station. Constantly changing those policies on the fly, such as whenever the post happened to get crowded, would put too big a gist on the network, Duncan same. Real-fourth dimension traffic steering will full complement ANDSF and other standards much as Hotspot 2.0, she said.

Ericsson's traffic-steering feature wish be an enhancement to the party's meshwork management computer software and will come by the best quarter of next year. It won't require any extraordinary computer software on handsets, though it volition only work with devices that prat use EAP (Protractile Authentication Communications protocol), according to Duncan. Virtually all smartphones birth EAP, she said.

The catch is that, for now in any case, carriers will have to use both cellular and Wi-Fi gear from Ericsson to get the boast, Duncan said. The core of the network put up be from another vendor, she aforesaid.

If a attack aircraft carrier uses two other suppliers for its network, as many do, then requiring special gear may hold up adoption of genuine-time traffic direction, Ovum's Schoolar said.

"You'Re passing to have a very different experience throughout your Wisconsin-Fi step. That is kind of a challenge with it in terms of selling it to mobile operators," Schoolar said.

At CTIA, NSN also announced period of time traffic steering, which it said carriers will be healthy to implement American Samoa an overlayer along top of whatever equipment they have in their cellular, Badger State-Fi and core networks. The new capability, part of the company's Smart Wisconsin-Fi portfolio, will be acquirable in the third fourth part, according to NSN.
