_link_parameter_report Enhancement to MIH Link Parameter Change Primitive  To facilitate upper layer handover decision making, it is important that an MIH user can effectively monitor certain link layer parameter values and their changes.  For architectural flexibility, three valid design approaches should be supported: 1.MIH user uses a poll command to get a report of the link parameters: - use MIH_Poll primitive 2.MIH user sets a threshold on a link parameter and the link sends a report when the link parameter crosses the threshold: - use MIH_Configure and Link_Configure_Thresholds to set up the threshold - use Link_Parameter_Change and MIH_Link_Parameter_Change (definition still missing) to report the values and changes. 3.MIH user asks the link to send a parameter report periodically: - currently no primitive can support this Solution: Enhance the current MIH Link Parameter Change primitive to support periodic parameter reporting

_link_parameter_report  MIH Link Parameter Change primitive already supports the following capabilities:  Can be triggered when a particular parameter crosses a pre-set threshold;  Report parameters for any links (serving and potential links) (clarify?)  Reports the current value of a list of parameters (clarify?)  The primitive can be used either by the terminal or by the PoA/PoS (clarify?)  The primitive can be local and remote.  We propose to add one new capability to support the timer-based link parameter report:  Can be also triggered on a regular basis determined by a configurable timer (new enhancement)  We also suggest to change the name of the primitive to MIH Link Parameter Report and propose its baseline text in Enhancement to MIH Link Parameter Change Primitive (cont.)
