<p>PROBLEM TO BE SOLVED: To provide a dynamic path designation method for wireless communication and its device. SOLUTION: A soft switch is used to mark all end points relating to a call, a path for wireless communication is dynamically designated, a message is generated as the entry of marked end points is updated and the message is sent to the soft switch. Receiving the message, the soft switch recalculates a series of updated network resources required to maintain this call, (i) instructs the updated network resource to negotiate medium transfer, (ii) transmits a proper call start message to a new resource after receiving an affirmative reply from the new resource and (iii) transmits a call release message to a preceding old resource that supports the call. The selection of a required and indispensable resource relating to a specific call is driven by the intelligence of a communication network topology. Thus, a resource closer to the end points is selected in terms of the topology and then the efficiency of the network resource can be enhanced on the basis of the network scale reference.</p> |
