Abstract
The method comprises: 1) access network sends an assignment message to the access terminal, which carries the information used for indicating the access network to assign a unicast access terminal ID to the terminal; 2) after receiving the assignment message, according to the message serial number the access terminal verifies the validity of the message; if it is invalid, sending a assignment-failing message to the access network; 3) after receiving the assignment-failing message from the access terminal, the access network stops the process and returns to the step 1.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method of handling single broadcast cut-in terminal identifying assignation failure.
Background technology
At CDMA2000 UMB (Ultra Mobile Broadband, super mobile broadband) in the technical specification, for adapting to the fast development of wireless network, in route chain of command (Route Control Plane) agreement, defined route opening acceptance (RouteOpenAccept) message, the data interface is assigned (DataAttachmentPointAssignment) message, single broadcast cut-in terminal identifying assignation (UATIAssignment) message, wherein:
Route opening is accepted (RouteOpenAccept) message, Access Network AN (Access Network) sends this message to access terminal AT (Access Terminal), as the response message and the single broadcast cut-in terminal identifying assignation message of the request of opening (RouteOpenRequest) message to route, this message comprises message sequence number (MessageSequence) field and the some other field that is used for the message validation verification.
The data interface is assigned (DataAttachmentPointAssignment) message, AN sends this message to AT, expression AN give new data interface of AT assignment (Data Attachment Point) and single broadcast cut-in terminal identifying assignation, and this message comprises message sequence number (MessageSequence) field and the some other field that is used for the message validation verification.
Single broadcast cut-in terminal identifying assignation (UATIAssignment) message, AN sends this message to AT, clean culture of expression AN assignment accesses terminal identification to being accessed terminal, and this message comprises message sequence number (MessageSequence) field and the some other field that is used for the message validation verification.
When sending the route opening that comprises single broadcast cut-in terminal identifying assignation, AN accepts (RouteOpenAccept) message, the data interface is assigned (DataAttachmentPointAssignment) message or single broadcast cut-in terminal identifying assignation (UATIAssignment) message, (UATIComplete) message is finished in identification but the clean culture of not receiving AT in the regular hour accesses terminal, AN accepts the route opening that re-transmission comprises single broadcast cut-in terminal identifying assignation, the number of times that data interface assignment messages or single broadcast cut-in terminal identifying assignation are certain, do not finish message if receive the clean culture of the AT identification that accesses terminal yet, AN will return a failure indication (Failed indication).
Route opening is accepted (RouteOpenAccept) message, and the data interface assigns (DataAttachmentPointAssignment) message and single broadcast cut-in terminal identifying assignation (UATIAssignment) message all can comprise single broadcast cut-in terminal identifying assignation information.At any time, AT receives that the route opening that comprises single broadcast cut-in terminal identifying assignation accepts message, data interface assignment messages and single broadcast cut-in terminal identifying assignation message, AT will carry out the validation verification of message according to message sequence number (MessageSequence), if message is invalid, AT will abandon this message.
In current treatment mechanism, if the route opening that the AT verification is received is accepted message, perhaps data interface assignment messages, perhaps single broadcast cut-in terminal identifying assignation message is invalid message, AT will abandon this message, do not indicate above-mentioned message to be dropped and do not return any message to AN, it is as follows to do the problem of bringing like this:
Cause unnecessary messages to retransmit, the waste air interface resource.When sending the route opening that comprises single broadcast cut-in terminal identifying assignation, AN accepts message, after data interface assignment messages or the single broadcast cut-in terminal identifying assignation message, finish message in the clean culture of the waiting for AT identification that accesses terminal, because AT has abandoned received message and has not notified AN, AN will retransmit route opening and accept message, and the number of times that data interface assignment messages or single broadcast cut-in terminal identifying assignation message are certain is indicated up to returning failure.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of access terminal method of identification domination failure of clean culture of handling, and improves the treatment effeciency of single broadcast cut-in terminal identifying assignation failure, and the message of avoiding there is no need retransmits.
For addressing the above problem, the present invention proposes a kind of method of handling single broadcast cut-in terminal identifying assignation failure, comprise the steps:
Step (1), Access Network send an assignment message to accessing terminal, and carry to be used to indicate clean culture of Access Network assignment to access terminal identification to the information that accesses terminal;
Step (2), access terminal receive this assignment message after, the validity of the described assignment message of verification if the described assignment message that Access Network sends is invalid, sends clean culture and accesses terminal Assignment Failure message to Access Network;
Step (3), Access Network receive from the clean culture that accesses terminal and access terminal after the Assignment Failure message, stop the described assignment message of retransmission steps (1) and are accessed terminal.
Further, said method also can have following characteristics, and described assignment message is that route opening is accepted message, perhaps data interface assignment messages, perhaps single broadcast cut-in terminal identifying assignation message.
Further, said method also can have following characteristics, comprises the message sequence number field that is used for the message validation verification in the described assignment message, in the described step (2) according to the validity of the described assignment message of described message sequence number field verification.
Further, said method also can have following characteristics, and in the step (3), the described clean culture that sends to Access Network of accessing terminal accesses terminal and comprises the message sequence number field value that causes described assignment message authentication failed in the Assignment Failure message.
Further, said method also can have following characteristics, in the step (2), if access terminal through verification, confirms that the described assignment message of Access Network transmission is effective, then accesses terminal and will carry out normal Message Processing.
Further, said method also can have following characteristics, and described method is applied in the code division multiple access CDMA2000 system.
By adopting method of the present invention, avoided unnecessary messages re-transmission in the system, effectively saved air interface resource, improved systematic function.
