T-Mobile Taps Tekelec for LTE Signaling

T-Mobile US Inc. has chosen Tekelec 's Diameter Signaling Router (DSR) to accelerate its Long Term Evolution (LTE) deployment and get ahead of signaling issues that could arise on its forthcoming 4G network.

The vendor announced Monday that T-Mobile, the fourth-largest wireless operator in the U.S., will use its DSR as the central control point to route policy, charging and subscriber messages on its LTE network, set to get up and running in 2013.

Tekelec says the DSR will help T-Mobile keep the cost of network updates down as it builds out LTE, as well as minimize congestion-causing signaling, which happens when data-centric apps constantly ping the network when in use or left running in the background.

Why this matters
T-Mobile is the last operator to begin constructing an LTE network in the U.S., and it will be playing catch-up for some time. It hopes the DSR will kill two birds with one stone -- help it scale its 4G faster and avoid some of the signaling issues that have plagued, even temporarily knocked out, some 3G networks.

For Tekelec, T-Mobile marks the latest in a string of DSR wins. It now has 19 customers, including Verizon Wireless and several other North American wireless operators.
