The present invention includes in core network i.e. SGSN, when determined idle signaling connection existent time exceeds scheduled time-value, then releasing said signaling connection. The present invention provides delay releasing based Iu connection management method in WCDMA system, avoiding releasing Iu connection with handset acting conflict, reducing user activating data service time delay.
Description
Technical field
The present invention relates to the WCDMA mobile communication system, relate in particular to the signalling connection managing method of a kind of radio network controller and core net interface.
Background technology
In WCDMA (Wideband Code Division Multiple Access (WCDMA)) system, when the user has the context signaling to transmit, connect to setting up a signaling that is used for carrier signaling message between the SGSN (Serving GPRS Support Node) at user terminal (as mobile phone).
As shown in Figure 1, in the WCDMA system, described signaling connects and is divided into two sections: one section be MS (travelling carriage) with RNS (RNS) between the Uu interface on RRC (Radio Resource control) be connected; Another section be RNS with SGSN between the Iu interface on Iu be connected.
In system, when no longer needing to transmit signaling message, this signaling connects and will be discharged by RNC among the RNS (radio network controller) and SGSN.Described SGSN can initiate to discharge the process that Iu is connected with RNC.After Iu connected release, RNC can remove the RRC that discharges pairing and connect.Simultaneously, when mobile phone will be done data service, RNC was necessary for the corresponding RAB of handset allocation (RAB) resource, these RAB resources are bound in the Iu connection, promptly have only Iu to connect and exist, RAB could exist, and is used for the transmission of bearing data service.
At present, in the Attach Request message and routing update message of mobile phone, all contain a cell " Follow On Request (subsequent request) ", this cell is used for mobile phone indication core net, finish adhere to the routing update flow process after whether require core net to prolong to keep Iu to be connected.Usually, according to agreement is understood, if terminal adhere to or routing update message in cell " Follow On Request " is changed to 1, promptly require CN (core net) to finish follow-up continuation of insurance with routing update and stay Iu to be connected adhering to, so that continuing to connect by Iu, terminal uploads signaling, the operation that needs aforesaid operations and then to activate PDP (packet data protocol) or send SMS message such as, mobile phone.If " Follow OnRequest " is changed to 0 with cell, then think mobile phone adhere to finish with routing update after, do not have follow-up signaling transmission activity, at this moment, connect just core net can discharge described Iu.
Yet, for the setting of cell since at present standard do not have clear and definite qualification, and core net manufacturer, manufacturer terminal do not have harmonious to the understanding of this cell setting yet, basically be that each manufacturer terminal is understood agreement according to own at present, " Follow On Request " cell value is set voluntarily.Therefore, in actual application, core net is difficult to judge whether to discharge described Iu signaling connection according to the setting of this cell.
In addition, some cell phone apparatus are in the signaling activity request message of initiating, and such as, deexcitation request etc., just do not comprise " Follow On Request " cell wherein at all, at this moment, obviously can't determine whether to keep Iu according to this cell and connect.Therefore, in the WCDMA actual application, can't determine whether to keep Iu according to the setting of " Follow On Request " cell and connect.
Problem at above-mentioned prior art exists describes below in conjunction with concrete present situation.
For example, the terminal of present part manufacturers produce, adhere to the routing update request message in the value of setting of " Follow On Request " cell of carrying be always 1, cause SGSN adhere to finish with the routing update flow process after, keep Iu always and connect, and in fact terminal is not uploaded the demand of any signaling and data.Simultaneously; because standard is not clearly stipulated; RNC does not do any protection to this situation yet; if making SGSN not discharge Iu connects; RNC does not initiatively discharge RRC yet and connects, and causes mobile phone to need to keep the connection of eating dishes without rice or wine always, and promptly RRC connects; therefore keep higher wireless receiving and dispatching power consumption, thereby shorten the cell phone standby time greatly.
In addition, part terminal production firm is arranged also, the value of " Follow OnRequest " cell that carries in Attach Request message always is set to 0, like this SGSN finish adhere to after, will discharge the Iu connection immediately.But in fact, mobile phone needed and then to initiate to activate the PDP operation after finishing probably adhering to originally, yet, discharged by SGSN because Iu connects, have at first initiate service request, rebuild a signaling and connect, then, could send and activate the PDP request message to SGSN, the time delay that this has obviously increased user's activating data service has influence on the quality of the service that operator provides for the user.
Except that above-mentioned two kinds of situations, also have a kind of application scenarios of reality to be exactly: the handling process of initiating deexcitation PDP when mobile phone, and when this is last PDP of user activated, then after its deexcitation handling process is finished, SGSN will can not receive any indication information from mobile phone.That is to say in this case, SGSN does not know what operation follow-up mobile phone will carry out.Therefore, SGSN will think has not had service needed to proceed, and can select to discharge immediately the Iu connection, and still, in fact the operation of mobile phone may be behind each PDP of deexcitation, initiates to activate new PDP immediately.Like this, the aforesaid operations process will cause mobile phone behind deexcitation PDP, because SGSN has discharged the Iu connection, must rebulid Iu and connect, and just can send new PDP and activate request, and same, this processing procedure has also increased the time delay of activating data service.
In sum, according to present protocol specification, and the uncertainty of mobile phone terminal realization, cause the cell phone standby time to be shunk greatly, the time delay that connects that needs are extra when perhaps causing the mobile phone activating data service, the time delay that makes activating service need is longer.Therefore, in order effectively to improve the service quality of communication system, and the performance of subscriber terminal equipment, press for and solve the existing problems of management method that signaling is connected between above-mentioned RNC and core net.

Embodiment
Core concept of the present invention is to provide a kind of based on the Iu connection management method that postpones to discharge in the WCDMA system, on the one hand can maximum possible avoid discharges that Iu connects and the behavior conflict of mobile phone, reduce the time delay of user's activating data service, can also prevent that on the other hand Iu from connecting the stand-by time shrink problem that does not discharge the mobile phone that causes for a long time.
That is to say, the present invention is for solving the variety of problems that exists in the prior art, and SGSN can take a kind of strategy that Iu connects that postpones to discharge, and promptly the signaling of each mobile phone and number pass activity end, do not discharge Iu immediately and connect, but discharge again after unified delay a period of time.
For the present invention there being further understanding, describe below in conjunction with the specific implementation of accompanying drawing to the method for the invention.
The specific implementation of method of the present invention specifically comprises following process as shown in Figure 2:
Step 21: the Iu that sets up user terminal connects, and promptly signaling connects, and starts a supervision timer immediately and monitor, and the time out period of timer can be configured according to actual needs by operator;
Step 22: supervision timer carries out timing, and when receiving up-downgoing signaling of user by described Iu, then described supervision timer just resets once, restarts to monitor timing at this Iu connection and handles;
For with the prior art compatibility, what the present invention needed to consider in the specific implementation process is: in core-network side, promptly on SGSN, if cell " Follow OnRequest " is arranged in the initial signaling request message of signaling process, and mobile phone finishes the back reservation or does not keep Iu to connect by the indication of " the Follow On Request " cell in request message flow process; No matter but why " Follow On Request " cell is worth on SGSN, after flow process finishes, does not all discharge Iu immediately and connect; If in the initial signaling request message of this signaling process, do not contain " Follow On Request " cell, SGSN is after signaling process finishes, and is same, also can not discharge Iu immediately and connect;
Step 23: judge whether described supervision timer is overtime, if overtime, then execution in step 24, otherwise continue execution in step 22;
Step 24: when supervision timer overtime, check the state of user terminal, if the user does not carry out any business, promptly judge in this Iu connection whether be attached with the business of handling, described business comprises that short message, location service, PDP (packet data protocol) activate, or the like, if corresponding business is arranged, then execution in step 25, otherwise, execution in step 26;
Step 25: discharge described Iu and connect, and stop the supervision timer that this Iu connects correspondence;
Step 26: if there is the corresponding business that connects based on this Iu, then do not discharge described Iu and connect, and this Iu connects and will be held always, when corresponding business finished, this Iu connected to carry with corresponding business and be released.
For the above-mentioned situation that a supervision timer is set that connects at each Iu: the client can dispose the length of timer, such as one minute, each Iu connects so all 1 minute periodicity supervision timer, when receiving or descend signaling, supervision timer resets, and promptly restarts; When the overtime time of supervision timer, then check whether to have to connect the business that realizes based on this Iu, do not connect if just discharge Iu, and stop supervision timer.
The present invention proposes a kind of realization thought that postpones release, the realization of concrete supervision timer can also be adopted various technical scheme.
Such as, can also in the SGSN system, only start a supervision timer or timer, unified monitoring scans the situation that all Iu connect, rather than each Iu connects supervision timer of startup;
Be specially respectively and carry out timing what each Iu connected, promptly when each Iu connects establishment, based on its corresponding creation-time under described monitoring timing or the timer record, when after this this Iu connects the signaling of a up-downgoing of every transmitting-receiving, then upgrade described Iu and connect corresponding creation-time information, just connect corresponding creation-time information based on monitoring timing or this Iu of timer record again;
Then, rely on system-wide supervision timer to scan the creation-time value information that each Iu connects periodically in batches, the Iu that promptly checks all existence connects corresponding creation-time information, and deduct the corresponding Iu that writes down previously with supervision timer or timer current time value and connect the time of transmitting last signaling, just can obtain the inertia time that this Iu connects, and determine whether that according to the length of its inertia time needs discharge this Iu and connect, promptly when the described inertia time surpasses predetermined value, then need further according to whether having professional the connection to determine whether to discharge this Iu connection attached to this Iu, otherwise, keep described Iu to connect;
When finding that those do not have data service to carry out, and the Iu that the inertia time has surpassed system configuration connects the inertia time that allows, and just initiatively discharges this Iu connection.
Situation for above-mentioned unified monitoring timer, be specifically as follows: the unified one-period timer that is provided with, such as time out period is 1 second, each overtimely just scan all Iu and connect, once 1 000 connections of continuous sweep at most, and once discharging 200 Iu at most connects, avoid endless loop, take the CPU time long, cause CPU fluctuation, when having scanned 1000, this connects or has discharged 200 connections, just stop this scanning, wait and proceed scanning behind the next timer expiry.
When scanning each connection, connect the time of the last activity of preserving according to this, and the current time, can calculate its inactive time span, the duration with client's configuration compares again, is configured to 1 minute such as the client, when transmitting signaling like this those last time to current scanning, surpassed 1 minute connection,, needs have been released if there is not the upper layer data business simultaneously.
Certainly, the mode that the present invention can also adopt other connects the Iu of each user terminal in the SGSN system and manages, be exactly total principle, it is long that each Iu is connected the time of setting to survive only under the situation of no signaling, nothing business, afterwards, will be released, thereby realize both can having guaranteed professional connectivity, reduce and create professional time delay, simultaneously, the negative effect that the long-time existence that can also effectively avoid invalid Iu to connect brings.
Be not difficult to find out, among the present invention, rely on above-mentioned treatment mechanism, behind any signaling activity end of user, SGSN can not discharge Iu immediately and connect.
If follow-up mobile phone will be initiated new signaling activity or data service, the signaling request of normal condition letter definitely should be in several seconds times after previous flow process finishes, the worst should be above 1 minute; Like this, as long as SGSN keeps Iu and connects a period of time, can be set to one minute such as the client, the Iu connection that then follow-up signaling activity just can use SGSN to keep is carried out, thereby guaranteed professional smooth and easy and continuity, effectively avoided conflict and its time delay of bringing.
Otherwise,, do not have ongoing data service simultaneously if the user back does not have new signaling activity to carry out yet, behind the timer expiry, Iu connects and can in time discharge, and RNC also can in time remove the RRC that eats dishes without rice or wine and connect, therefore mobile phone can not increase power consumption yet, does not influence the stand-by time of mobile phone.
In sum, the present invention effectively avoids discharging the signaling activity conflict that Iu connects and mobile phone is initiated by postponing release tech, reduces the time delay of user's activating data service, stops Iu simultaneously and connects the stand-by time shrink problem that does not discharge the mobile phone that causes for a long time.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
