IS-Wireless, a Warsaw-based LTE/LTE-Advanced IPR provider, announces availability of SON-ready LTE/LTE-A protocol stacks for UE and eNB. LTE STACKS are advanced software libraries realizing functions of L2 and L3 protocols. They are written in ANSI  C according to the latest 3GPP E-UTRA Rel. 10 with backward compatibility with Rel 8 and 9. LTE STACKS are key software elements of 4G modems for LTE/LTE-A mobile terminals (smartphones, tablets, USB sticks, laptops, etc.) and small cell base stations (femto-, pico-, micro-cells). Target group of customers include silicon vendors, ODMs, OEMs, integrators and research institutions.

“Adding LTE STACKS, a new family of products, to our portfolio is a natural consequence of our past track record and realization of a long-term market strategy. Thanks to the partnership in 5GNOW our stacks are designed to be future proof and ready to include forthcoming technical advances such as SON features or M2M support. Our strong commitment is visible in covering both sides of the radio interface i.e., both UE and eNB. We are motivated to deliver the most innovative LTE protocol stack to our customers. At this stage we would like to encourage all potential customers to get involved in the process of priceless customizations.” says IS-Wireless’ CEO Dr. Slawomir Pietrzyk.

LTE STACKS include SON-ready implementation of fully featured 3GPP E-UTRA Layer 2 and Layer 3 protocols for both UE and eNB as depicted in the Figure above. In addition to LTE UE and LTE eNB stacks we also implemented MME emulator for NAS signaling termination, as well as supporting protocols such as S1-AP and X2-AP. As a consequence our stacks are SON-ready and hence future proof.

Implementation in ANSI-C portable on various hardware platforms Multi-threading for support of parallelism of several entities (belonging to the same protocol or to the same node) Hardware Abstraction Layer (HAL) for independence on underlying hardware platform NAS / RRC interworking (e.g. state machines interworking, NAS message encapsulation within proper RRC message) NAS / RRC procedures (e.g. taking proper actions upon receiving specific message) Individual L2 protocol configuration by RRC RRC/X2-AP/S1-AP encoding / decoding with the use of ASN.1 L2 processing algorithms (e.g. ciphering, segmentation) Individual L2 protocol procedures (e.g. data processing) and L2 interworking procedures (e.g. MAC-RLC data exchange) PDU creation for each L2 protocol Logical, transport and physical channel mapping PHY layer parameters configuration (e.g. DCI setting) RRM functionalities (e.g. scheduler, link adaptation, handover, admission / congestion control) “SON-ready” functionalities (e.g. SON interface, KPI measurements, L2 measurements, X2/S1 interface features) Support for interworking with GSM and UMTS (e.g. NAS and RRC messages and configuration) PHY abstraction: TS 36.213, TS 36.214 MAC: TS 36.321 RLC: TS 36.322 PDCP: TS 36.323 RRC: TS 36.331 NAS: TS 24.301, TS 23.401 X2-AP: TS 36.423 S1-AP: TS 36.413 Security: TS 33.401, TS 32.215, AES, SNOW 3G specifications RoHC: IETF RFC 4995, IETF RFC 4996, IETF RFC 3095, IETF RFC 3843, IETF RFC 4815, IETF RFC 5255 ASN.1: ITU-T X.680, ITU-T X.690, ITU-T X.691, ITU-T X.693 Overview and RRM: TS 36.300, TS 36.304, TS 36.302, TS 36.133 KPI / L2 measurements: 32.450, TS 36.314, TS 32.425
