The core network requirements for next-generation Long Term Evolution (LTE) are so demanding that vendors have revamped their products and strategies, Unstrung has found.

As vendors jostle for position to prove they have what it takes in LTE and the Evolved Packet Core (EPC), Ericsson AB (Nasdaq: ERIC) is so far the only vendor with more than one operator customer for EPC equipment. Telia Company and Verizon Wireless have both selected Ericsson, not only for LTE radio access equipment, but also for EPC gear. (See TeliaSonera: We'll Do 4G in 2010 and MWC 2009: Verizon Picks LTE Vendors.)

Other vendors have clocked up important early wins, too: Verizon has chosen Alcatel-Lucent (NYSE: ALU) and Starent Networks Corp. (Nasdaq: STAR), along with Ericsson, to supply EPC equipment. TeliaSonera has picked Huawei Technologies Co. Ltd. and Ericsson for its LTE core network. (See After Verizon, What's Starent's Next Move? and MWC 2009: Starent Dines on LTE.)

In Japan, NTT DoCoMo Inc. (NYSE: DCM) has selected NEC Corp. (Tokyo: 6701), as well as Nokia Networks , in partnership with Fujitsu Ltd. (Tokyo: 6702; London: FUJ; OTC: FJTSY), to supply EPC equipment. And even Nortel Networks Ltd. announced a partnership with Hitachi Ltd. (NYSE: HIT; Paris: PHA) to supply KDDI Corp. 's EPC equipment. (See DoCoMo Picks NEC for Super 3G, Fujitsu Wins 'Super 3G' Deal , and Nortel Snares LTE Core Deal.)

In addition, mobile core specialist Starent has sealed 3G network deals with U.S. cable operator Cox Communications Inc. and Austrian operator Mobilkom Austria AG & Co. KG , to supply equipment that is software upgradeable to support the operators' planned LTE core networks. (See Mobilkom Picks Starent and Starent at Core of Cox's 3G Push.)

The LTE core challenge
LTE networks are not just about ramping up the mobile access network to theoretical peak rates of 150 Mbit/s [ed. note: emphasis on theoretical there]. It will also require a major overhaul in the packet core network. The role of the EPC in next-generation mobile networks will be more critical than in 3G networks, because the new packet core will have to handle a much heavier data traffic load and deliver real-time rich media services, such as VoIP and video, over an all-IP packet architecture.

To meet these capacity and service delivery challenges, equipment suppliers will have to introduce new platforms for their EPC network elements.

"The EPC needs more capacity and more features, which calls for a new platform," says Heavy Reading senior analyst Gabriel Brown. "The packet core market has been a bit under-invested historically. But with all the growth in HSPA traffic and expectations for LTE, operators are looking for a new generation of equipment, and vendors are stepping up their investments."

The packet core market is low volume in terms of units shipped, but racks up around $1.4 billion in annual revenues, according to Brown. Given how critical and strategic the equipment is to carriers, Heavy Reading believes the EPC market is set for sustained revenue growth, according to its recent white paper, "LTE/SAE & the Evolved Packet Core: Technology Platforms & Implementation Choices."

There are four network elements in the EPC: a Mobility Management Entity (MME), Policy and Charging Rules Function (PCRF), the Serving Gateway, and the Packet Data Network (PDN) Gateway. LTE rivals have been hard at work on revamping the underlying platforms for these EPC elements, and the resulting choice for carriers is varied, ranging from edge routers to ATCA platforms and in-house solutions.

Here's a snapshot of vendors' EPC platform choices:

re: Core Network Challenges LTE Vendors


LTE eNODE B implementation and LTE UE Data cards implementation has made very good progress in the development, still the following Challenges are have been faced by the Industry:
1. LTE IOT with all the eNODE B Devices will not happen until Mid 2010 or end of 2010.


2. Still LTE Forum has not formalized the LTE Test Plans and Spec's adequate to test coverage  for all the key functionality of the LTE Multi mode devices.


3. LTE eNODE B and LTE UE Devices with MME, SAE and PDN Gateway level IOT and interfaces issues between multiple venders are not yet identified.


4. LTE Operator Policies and Charging Rules for each operator is varying, still there is no common structure evolved in order to support the True LTE network in the field.


SAI Technology has working eNODE B Protocol stack and LTE UE Protocol stack going through IOT testing. SAI Technology can enable and support the System integration, IOT, advanced System level software applications. SAI Technology has end to end Syetem working in the lab for the VOIP, Streaming Video, data and Multimedia application support.


We are LTE Specilized company, we can support to resolve some of the fundamental issues with LTE in the earlys stages of the development.
