3GPP Sews Up LTE Specs

9:25 AM -- The final work on the next-generation mobile broadband standard Long Term Evolution (LTE) was finalized last month, Unstrung has learned.

At the 3rd Generation Partnership Project (3GPP) meeting last month, the standards body approved the straggler specs that were delayed and given an extended deadline until March, which were mostly to do with the Systems Architecture Evolution (SAE) and Evolved Packet Core (EPC). (See 3GPP Pins Down LTE Specs.)

That means the standards work on the new packet core has now caught up to the work on LTE in the radio access network and has met all the objectives to be included in the 3GPP's Release 8 set of standards.

And the standards body got a good indication that vendors were already using the new LTE standards in product development by the staggering number of change requests approved at the March meeting (just in case it wasn't obvious from the CTIA show last week that things are really starting to happen with LTE). There were 2,500 change requests made at the March 3GPP meeting, according to Adrian Scrase, vice president of international partnership projects at the European Telecommunications Standards Institute (ETSI) . To put that in perspective, there are typically about 1,000 change requests made at each 3GPP quarterly meeting, he explains.
