Due to, the precision grade of Tong Walk signals is higher, error is smaller, so as to user equipment should the same Walk signals of full accuracy rank that can receive of prioritizing selection oneself forwarded, now, user equipment D is simultaneously in the coverage in user equipment C and user equipment E, and after 2 Tong Walk Signal averagings that 3 Tong Walk signals of user equipment C forwardings are forwarded with user equipment E, for 2 Tong Walk signals, and if user equipment D-straight state in the forwarding user equipment C 3 Tong Walk signals sent, 2 Tong Walk signals transmitted by user equipment E can not just be received.Then user equipment D can be mistakenly considered user set transmitted by E be also only one 3 grades with Walk signals, so as to will not give up what oneself was being tracked
3 Tong Walk signals that user equipment C is sent transfer 2 Tong Walk signals of tracing customer equipment E transmissions.Then the chance for obtaining higher level Tong Walk is lost.
So user equipment D should random forwarding for receive, to determine whether the same Walk signals of higher precision rank.
When user equipment D forwardings to receive, when starting to receive Tong Walk signals, 2 Tong Walk signals of user equipment E transmissions will be received, and this 2 Tong Walk signals are forwarded.
