Abstract

The invention discloses a processing method of a wireless network controller on the error indication, which is applied to the third generation of mobile communication system. When the tunnel endpoint of the customer plane of the tunneling protocol at the side of the wireless network controller receives the error indication, the error indication is submitted to the control plane of the wireless network controller after being delayed for a while. The invention solves the problem that after the GTP-U tunnel endpoint at the RNC side receives the error indication transmitted from the SGSN during the normal hang-up of the PS service initiated by MS, the RNC control plane is triggered to initiate an abnormal flow for releasing the RAB.

Description

A kind of radio network controller is for the processing method of mistake indication

Technical field

The present invention relates to 3-G (Generation Three mobile communication system), relate in particular to the processing method of a kind of radio network controller (RadioNetwork Controller is hereinafter to be referred as RNC) for mistake indication (Error Indication).

Background technology

According to prior protocols flow process in the 3-G (Generation Three mobile communication system); At MS (Mobile Station; Portable terminal) normally initiates PS business (Packet Switch is professional, packet switching service: such as the GPRS online) when hanging up, the GTP-U of RNC side (User plane of GPRS Tunneling ProtocolGPRS; The tunnel protocol user plane) endpoint of a tunnel may be received the mistake indication that SGSN (Service GPRSSupporting Node, Serving GPRS Support Node) sends.

According to 3GPP (3rd Generation Partnership Project; Third generation partner program) agreement; Initiate by MS to initiate PDP (Packet DataProtocol at MS through UTRAN (UMTS TerrestrialRadio Access Network, the unlimited Access Network in UMTS land) in the flow process of deexcitation request; Packet data protocol) context deexcitation request (Deactivate PDP Context Request) is called RAB (Radio Access Bearer to SGSN; RAB) appointment process discharges before the RAB, and the GTP-U endpoint of a tunnel of RNC side still has upstream data and sends to SGSN, if when data send to SGSN just; SGSN has received GGSN (Gateway GPRS SupportNode; The PDP Context deletion response (Delete PDP ContextResponse) of Gateway GPRS Support Node) sending, then SGSN can send wrong indication to RNC because of can not find corresponding PDP Context.

The GTP-U endpoint of a tunnel of RNC side is received the chain of command that reports RNC after mistake is indicated, and chain of command thinks that the professional generation of PS is unusual, and initiation is because of the unusual RAB release flow that triggers.

Though this meets present agreement, the professional release flow of same normal PS both possibly be to discharge through normal flow, also possibly discharged by unusual flow process, and this is unreasonable.

In this case; The GTP-U endpoint of a tunnel of RNC side is received the mistake indication that SGSN sends, though probability is lower, inevitably; If think to eliminate fully this possibility; Need in the existing protocol flow process, increase interacting message with after guaranteeing that SGSN has received PDP Context deletion response, the GTP-U endpoint of a tunnel of RNC side no longer sends to SGSN with upstream data, and the communication-cost that this method is brought is unnecessary on the contrary.

Summary of the invention

The present invention provides a kind of RNC processing method for mistake indication, receive the mistake indication that SGSN sends with the GTP-U endpoint of a tunnel that solves the RNC side after, trigger the RNC chain of command and initiate unusual flow process and carry out the problem that RAB discharges.

For solving the problems of the technologies described above; The present invention provides a kind of RNC processing method for the mistake indication; Be applied to 3-G (Generation Three mobile communication system); The tunnel protocol user plane endpoint of a tunnel of said radio network controller side receives that said wrong indication through after the time of delay, reports said wrong indication the chain of command of said radio network controller.

The method of the invention; Wherein, The numerical value of said time of delay is more than or equal to the time the message of receiving the RAB release that Serving GPRS Support Node sends from the normal initiation packet reciprocal exchange of business of portable terminal hang-up request to said radio network controller.

The method of the invention, wherein, be stored in the database of said radio network controller said time of delay.

Through time-delay; Make that the PS business is discharged through normal flow by the RNC chain of command during this period; And the GTP-U endpoint of a tunnel of RNC side also has been released; Corresponding error indication will can not be reported to the chain of command of RNC, not initiate unusual flow process and will carry out RAB and discharged thereby also can not trigger the RNC chain of command.

And received wrong indication for the GTP-U endpoint of a tunnel of RNC side under other situation, and still can normally send to the RNC chain of command, guarantee the normal release of resource.And, after handling like this, be equivalent to filter unfavorable wrong indication, discharge then more effective for the RNC statistics because of the RAB that triggers unusually.

Description of drawings

Fig. 1 is the process flow figure of a kind of RNC of the embodiment of the invention for the mistake indication.

Embodiment

Describe the present invention below in conjunction with specific embodiment, but not as to qualification of the present invention.

The present invention is exactly in order to solve the shortcoming in the above-mentioned existing protocol flow process of mentioning; Use simple and effective way; And need not change the existing protocol flow process; Only after the GTP-U of RNC side endpoint of a tunnel is received wrong indication, report the RNC chain of command again, then can guarantee can not trigger the RNC chain of command and initiate unusual flow process and carry out RAB and discharge through suitable time-delay.

As shown in Figure 2, a kind of RNC of the embodiment of the invention is applied to 3-G (Generation Three mobile communication system) for the process flow of mistake indication, comprises the steps:

Step 201 for the GTP-U endpoint of a tunnel disposes a time of delay, is called Time_delay in the database of the RNC of 3-G (Generation Three mobile communication system);

Step 202, the GTP-U endpoint of a tunnel of RNC side are received wrong indication;

After step 203, GTP-U endpoint of a tunnel postpone through said Time_delay, report said wrong indication the chain of command of RNC again.

The numerical value of above-mentioned said Time_delay is more than or equal to the time the message of receiving the RAB RAB release that Serving GPRS Support Node SGSN sends from the professional hang-up request of the normal initiation packet exchange of mobile terminal MS PS to said RNC.

Through after the above-mentioned processing; When MS normally initiates the PS business and hangs up; The GTP-U endpoint of a tunnel of RNC side still may be received the mistake indication that SGSN sends, but because the time delay of having passed through Time_delay, the PS business discharges through normal flow; And the GTP-U endpoint of a tunnel of RNC side also is released in this process, and the corresponding error indication will can not report the chain of command at RNC.Therefore these unfavorable wrong indications are rationally filtered.

GTP-U endpoint of a tunnel for other situation (not being the professional dispose procedure of normal PS of being initiated by MS) RNC side is received wrong indication, through the Time_delay time, still can report the RNC chain of command, can guarantee resource is normally discharged.

In the 3-G (Generation Three mobile communication system) according to the invention; The GTP-U endpoint of a tunnel of RNC side is when receiving wrong indication; Through reporting the chain of command of RNC behind the suitable time-delay, processing can avoid triggering the irrational unusual RAB release flow of RNC chain of command initiation when mobile phone is normally initiated the PS business and hung up like this; Unfavorable wrong indication is rationally filtered; Make flow process simple, help the stability and the reliability of the system that guarantees, also help RNC the RAB dispose procedure of real exception-triggered is carried out correct statistics.

Method of the present invention is not restricted to listed utilization in specification and the execution mode.Under technology of the present invention, the those of ordinary skill in field, can make various corresponding changes and distortion, and all these corresponding changes and distortion all belong to the protection range of claim of the present invention according to the present invention.
