Background IEEE 802.21 standard draft is approaching letter ballot state in the next plenary One important factor in the handover procedures is the ability to monitor the various link threshold parameters Current draft only has a short list of examples in this area The architecture discussion that is starting/ongoing within 802 wireless groups will most likely not meet the timelines of 802.21 The aim of this submission is to give an overview of what relevant link layer parameters are already existing in different media specific groups, using the latest drafts and proposals of the relevant groups Based on the findings, a proposal for the parameter list to be used in 802.21 is given The aim is to give a generic, but yet detailed enough list of parameters, which should be as close as possible to the native parameters within the media specific technologies but still be relevant for the handovers 21-06-0493-00-0000

802.11 The 802.11e (D13) chapter 7.3.2.15 ’Traffic Specification (TSPEC) element has the following parameters: Nominal and Maximum MSDU size Minimum and Maximum Service Interval Inactivity Interval Suspension Interval Service Start Time Minimum, Mean and Peak Data Rate Burst Size Delay Bound Minimum PHY Rate Surplus Bandwidth Allowance Medium Time 21-06-0493-00-0000

802.16 The following parameters originate from 802.16g-05/008r2 chapter 14.5.6.4 ’QoS Management’ , 802.16e (D11) chapter 6.3.14.4.1 ’Global Service Flows’ and 802.16e (D11) chapter 11.13 ’Service Flow Encodings’ QoS Parameter Set Type Maximum Sustained Traffic Rate Maximum Traffic Burst Minimum Reserved Traffic Rate Service Flow Scheduling Type Tolerated Jitter Maximum Latency And TLV encodings include ’Packet Error Rate’ for Service Flow 21-06-0493-00-0000

802.20 No draft exists yet for 802.20 Contribution C802.20-06/04 chapter 3.3.6.2.9.1 ’Definition of QoSAttributeSet’ states the following parameters: Peak_Rate Bucket_Size Token_Rate Max_Latency Max_Packet_Loss_Rate Packet_Size Max_Jitter 21-06-0493-00-0000

3GPP The following parameters originate from 3GPP TS 23.107 v.6.3.0 Traffic class Maximum bitrate (kbps) Guaranteed bitrate (kbps) Maxim SDU size (octets) SDU format information (bits) SDU error ratio Residual bit error ratio Delivery of erroneous SDU (yes/no) Transfer delay (ms) Traffic Handling priority Allocation/Retention Priority Source statistics descriptor Signalling Indication (yes/no) 21-06-0493-00-0000

3GPP2 The follwoing parameters originate from TIA-835.4-D Table E-5 Content of QoS_Attribute_SET Qos_ATTRIBUTE_SET_ID (7 bits) VERBOSE (I bit) FlowProfileID (0 or 16 bits) Traffic_Class (0 or 3 bits) Peak_Rate (0 or 16 bits) Bucket_Size (0 or 16 bits) Token_Rate (0 or 16 bits) Max_Latency (0 or 8 bits) Msx_IP_Packet_Loss_Rate (0 or 5 bits) Packet_Size (0 or 8 bits) Delay_Var_Sensitive (0 or 1 bits) 21-06-0493-00-0000

Proposed Change for 802.21 Change the link parameter list in ’Configure Thresholds’ and ’Parameters Change’ primitives throughout the document to following: Maximum Bit rate Guranteed (minimum) Bit Rate Peak Rate Packet Loss Rate Before Retransmission Packet Error Rate Maximum Packet (SDU) Size Delay Jitter Received Signal Strength Provide detailed enough description of the meaning and interpretation of each parameter, to ease interoperability and other issues Vendor specific enhancements should also be allowed 21-06-0493-00-0000
