5.2.7 P2P route establishment 5.2.7.1 Storing mode Change the first paragraph of 5.2.7.1 as indicated: When a device receives a P2P-RQ IE, if it has no existing path to the source of the P2P-RQ IE, it stores the information retrieved from the P2P-RQ IE into a new entry in the P2P path list Route Table in the MT. The address of the neighbor from which the P2P-RQ IE is received is recorded in the Next hop -Route information of the P2P path_ Route Table. The device calculates or measures the LQM between itself and the neighbor from the previous hop and adds the result to the PQM value found in the IE. The device then stores the result into the PQM Value of the P2P path -Route Table entry. Change the fourth and fifth paragraphs of 5.2.7.1 as indicated: If the PSN in the latest P2P-RQ IE is equal to the recorded PSN, the device compares the PQM value of the two P2P-RQ IEs. If the PQM value of the latest P2P-RQ IE is equal to or greater than that of the previous P2P-RQ IE, the latest P2P-RQ IE is discarded. Otherwise, the device replaces the value of Next hep .Route information with the address of neighbor from which the latest P2P-RQ IE has been received, and replaces the PQM value with the PQM provided by the current neighbor. The IE is then discarded. If the PSN of new P2P-RQ IE is newer than the recorded PSN, the device calculates the PQM between the device and the source of the P2P-RQ IE. All elements of the P2P path -Route Table are updated with the information from the latest P2P-RQ IE and with the newly calculated PQM value.
When the P2P-RP IE reaches the device with the address found in the P2P SA field, the device delivers the path and the source address therein to the next higher layer with the L2RLME-INTERMEDIATE-ADDR- LIST.indication primitive. The device also creates a new entry in the P2P path list .Route Table of the MT where the Destination address is set to the address retrieved from the P2P DA field of the P2P-RP IE, and the PSN, the PQM value and the Intermediate Address List are set to the values retrieved from the corresponding fields in the IE.
