Abstract: Disclosed is an interactive method for reporting location reports by a target UE  in an LCS. The method comprises: the target UE receiving a location request initiated by an applicant and reporting a location report to the LCS system after detecting the occurrence of an event triggering a location report; the LCS system returning to the target UE a location report acknowledgement after receiving the location report submitted by the target UE. Further, while submitting the location report to the LCS  system, the target UE starting a timer designating a time period and judging whether it has received a location report acknowledgement returned by the LCS system within the designated time period, if yes, stopping the timer designating the time period;  otherwise, reporting once again the location report to the LCS system and re-starting the timer designating the time period at the same time. In accordance with this method, errors in reporting location reports are reduced and the uncertainty in implementation of LCS is lowered.

Abstract: A sidewall of a trailer is formed from at least two composite panels joined together by a novel joining configuration. Each panel is formed from inner and outer thin metal skins and a plastic core sandwiched between the skins. In several embodiments, at least one of the skins has at least one end coined to as to compress the core between the skins to define a coined end section. A logistics plate and a splicing member are used to join the panels together and are secured thereto by rivets. The logistics plate and/or the splicing member may sit against the coined end sections. The splicing member may have flat top and bottom portions to facilitate in the attachment of the panels to the top and bottom rails of the trailer. In other embodiments, a logistics plate is secured by rivets to the panels for joining them together. The splicing member is eliminated and instead, the outer skin of at least one panel is extended to lie behind the logistics plate. In yet another embodiment, the inner skin may have rolled or formed grooves to provide a smooth transition from a logistics plate having rolled edges. An insert may be used between the skins where the rivets are inserted in any of the embodiments to substantially prevent compression of the panels.
