It defies the functionality required for the support of packet services over HIPERACCESS 2. Separate ETSI documents provide detai

12、ls on the system overview, data link control layer, radio link control sublayer, other convergence sublayers and conformance testing requirements for HIPERACCESS. The Packet based Convergence Layer is split into two parts, a Common Part and a Service Specific Part. The Common Part describes the func

13、tionality for adapting variable length packets/frames to the fixed size data units used at the Data Link Control (DLC) layer 11 while the Service Specific Part describes the functionality required to support a certain protocol, e.g. Ethernet or IP. It is envisioned that several, independent, Service

14、 Specific Convergence Sublayers (SSCS) will be defied in the future as market requirements develop. The SSCSs all use the services of the Common Part and the DLC. The present document is part 1 of a multi-part deliverable covering the Packet based Convergence Layer, as identified below: Part 1: “Com

15、mon Part“: Part 2: “Ethernet Service Specific Convergence Sublayer“. Further SSCSs may be added in the future. ETSI 5 ETSI TS 102 117-1 VI .I .I (2002-09) 1 Scope The present document is applicable to HIPERACCESS equipment supporting packet services, such as Ethernet, IEEE 1394 4 or IP. The present

16、document does only address the functionality required to transfer variable length packetdframes over the radio interface between an HIPERACCESS Access Point and Access Terminal. It does not address the requirements and technical characteristics for wired network interfaces at the Access Point and at

17、 the Access Terminal. The Packet based Convergence Layer stack consists of a Common Part, defiied in this document, and Service Specific Parts that are defiied in separate documents. The Service Specific Convergence Sublayers all use the services provided by the Common Part and the HIPERACCESS Data

18、Link Control (DLC) layer i. The task of the Common Part of the Packet based Convergence Layer is to adapt variable length packetdframes to the fixed data unit size used in the HIPERACCESS DLC layer i. The present document does not address the requirements and technical characteristics for conformanc

19、e testing. These are covered by separate documents. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication andor edition number or version numbe
