Abstract
The invention discloses a method for accurately locating communication control port CCP errors, which belongs to the mobile communication system field. The method comprises: after a wireless network controller builds a wireless link with a node B, the node B notifies the configured node B communication contexts and correlative communication control ports to the wireless network controller through response messages of the wireless link, then in the process of message interaction between the wireless network controller and the node B, when a receiving side receives messages containing the node B communication contexts on other communication control ports besides the communication control ports, then failed response messages or error indication messages are returned to a sender, and error cause values in the response messages or error indication messages are communication control port errors. The method makes error investigation process simple and easy, and makes definite the error cause range, thereby realizing the accurate location of errors and greatly simplifying the system complexity additionally.
Description
Technical field
The present invention relates to the mobile communication system field, relate in particular to a kind of method that communication control port CCP (Communication Control Port) mistake is accurately located.
Background technology
In the 3G (Third Generation) Moblie project organization (3GPP) agreement, Iub (interface between the RNCand the Node B) mouthful Node B is used in signaling NBAP (the Node B Application Part Singal) agreement, defined the multiple error reason value in the protocol interaction process of radio network controller (RNC) (Radio Network Controller) and Node B (Node B), the mistake in mutual has accurately been located to help RNC or Node B.But,, lack corresponding positioning means for the mistake of CCP.
In the practical application, can dispose a plurality of CCP ports between a RNC and a Node B.And at each CCP port, RNC and Node B all need to know its port information---for example CCP identifies the transmission bearer of CCPID (Communication Control Port Identifier), CCP port correspondence etc.If the information inconsistency of the CCP port that RNC and Node B know then can break down in the NBAP protocol information of follow-up Iub mouth is mutual.
For example, RNC thinks that port is that the corresponding transmission bearer of CCPID=N is A, and Node B thinks that then port is that the corresponding transmission bearer of CCPID=N is B, and wherein A is not equal to B.Set up in (Radio Link Setup) process at Radio Link like this, Node B sets up at Radio Link and has distributed Node B communication context NBCC (Node BCommunication Context) in the response message (RadioLink Setup Response), and the CCP related, i.e. CCPID=N with this NBCC.Afterwards, RNC will send the NBAP message relevant with this NBCC on transmission bearer A, and Node B waits for these message on transmission bearer B; The perhaps NBAP message that Node B sends on transmission bearer B and this NBCC is associated, and RNC waits for these message on transmission bearer A, finally caused the failure of interacting message between RNC and the Node B.
Do not discuss how to handle above-mentioned mistake in the present agreement, if take place, the system that has realized usually adopts following method:
(1) directly abandon NBAP message from wrong port, at this moment, multiple reasons such as radio layer, transport layer, physical layer are arranged owing to information drop-out, investigation gets up to waste time and energy;
(2) return to wrong indication of the other side, owing to do not have clear and definite available error reason value in the agreement, generally just extend this as " uncertain reason " (Unspecified), " transfer resource is unavailable " (Transport resource unavailable) etc., this moment, the error reason scope was indeterminate, and contain extensivelyr, can't clearly locate;
(3) monitor all CCP ports, in case find and the not related NBCC message of this CCP, transmit and compatible processing by some software/hardwares, to ignore such mistake, simultaneously greatly increase the complexity of system against the NBAP agreement this moment.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of to the accurate method of location of communication control port error, thereby undertaken in the NBAP protocol interaction by the Iub mouth at RNC and Node B, realizes the accurate location to the CCP mistake.
The invention provides, a kind of method that communication control port error is accurately located, this method is after radio network controller and Node B are set up Radio Link, Node B is notified described radio network controller by the Radio Link response message with the Node B communication context of configuration and the communication control port that is associated thereof, carry out in the message interaction process at radio network controller and Node B afterwards, when the recipient has received the message that comprises described Node B communication context on other communication control port beyond the described communication control port, then return failure response message or wrong Indication message to transmit leg, the error reason value is " communication control port error " in this response message or the wrong Indication message.
Said method also comprises transmit leg according to the error reason value, and further whether analysis has used wrong communication control port to send message, perhaps examines the carrying of communication control port correspondence.
In the said method, carry the identification information of described Node B communication context in the described Radio Link response message and the identification information of the communication control port that is associated.
The message interaction process that described radio network controller and Node B are carried out is that Radio Link increases request process, synchronised radio link reprovision set-up procedure, asynchronous wireless links reprovision process or special measurement initialization procedure, in aforementioned process, Node B is returned failure response message as described sending direction radio network controller.
The message interaction process that described radio network controller and Node B are carried out is Radio Link delete procedure, special measurement termination procedure, downlink power control procedure, compact model command procedure or Radio Link activation, in aforementioned process, Node B sends wrong Indication message as described sending direction radio network controller.
The message interaction process that described radio network controller and Node B are carried out is special measurement reporting process, Radio Link Failure process, wireless link recovery process, Radio Link preemption processes, carries process and the radio link parameter update process rearranged, in aforementioned process, radio network controller sends wrong Indication message as described sending direction Node B.
Error reason to the CCP port in the inventive method has carried out the expansion classification, the error reason value is set to Communication Control Port Error, and whether the recipient can analyze and used wrong CCP port come to send out message, perhaps examine the carrying of CCP port correspondence etc., thereby make that wrong investigation process is simple, and clear and definite error reason scope has promptly realized wrong accurate location, has also simplified the complexity of system in addition greatly.
