Tradeoffs Method 1 Allow more possible different type of queries Restrict the query can be only one query type Method 2 Allow up to limited amount of number type of queries Allow different query types to be in the same request message Both Eliminate one additional level of encapsulation of query Reduce one TLV assignment
Modifications Required Merge MIIS Binary Query and MIIS Query Parameters. Move the MIIS_TLV_QUERY p66L11-28 to section 8 Merge into MIIS Query parameters p203 L35 Merge MIIS Binary Response and MIIS Query Response Move the MIIS_TLV_RESPONSE p69L33-48 to section 8 Merge into MIIS Query respones p204 L9 MIH_Get_Information request and response messages in and descriptions should be verified with this changes.
