Abstract
The present invention discloses a method for using a movable timer in a general packet radio service system. The method informs an LLC to start the movable timer after a mobile user is accessed to a GMM, the LLC restarts the movable timer every time when the LLC receives the uplink data of the mobile user, and then the uplink data is transmitted to a network layer; thus, the LLC takes over the movable timer managed by the GMM so that when the LLC receives the uplink data every time, the LLC does not need to frequently inform the GMM, but informs the GMM once after the movable timer times out so as to greatly reduce the information interactive quantity between the LLC and the GMM and further reduce the processing load of the GMM.
Description
Technical field
The present invention relates to a kind of using method of the active time in GPRS (GPRS) system.
Background technology
In the core net of whole gprs system, mobile subscriber's management is finished by GMM (GPRS mobile management module).GMM is responsible for mobile subscriber's present located state is controlled, and the signaling message that receives the mobile subscriber is also handled, and control mobile subscriber's access is adhered to and separated etc.In order accurately to obtain the current present position of mobile subscriber and at network side the mobile subscriber to be carried out State Control, GMM need monitor active situation with accurate understanding mobile subscriber to each mobile subscriber's uplink and downlink data.Like this, between GMM and LLC (logic link control module), need a large amount of interaction messages and carry out state synchronization.Because in gprs system, not only support general speech business, also support image communication, high-speed data service and Packet Service at a high speed, and may in synchronization, there be a large number of users to carry out information interaction by core net and external packet application network simultaneously, this just requires system to have higher load disposal ability, can handle the business datum that moves the uplink and downlink of supporting the user from difference in time.Because the user carries out unified management by GMM in gprs system, the residing position of GMM belongs to layer 3 agreement, and it mainly handles mobile subscriber's layer 3 signaling message, so that signaling is managed.The signaling message of this layer 3 might not need to transmit for a long time, for example may carry out the transmission of data for a long time in the user carries out the transport process of data service and does not have the transmission of signaling.GMM will can not receive any message from the mobile subscriber for a long time like this, can't know whether current mobile subscriber still is in the activity.In order accurately to know the situation of carrying out of mobile subscriber's current business, stipulated a general processing method among standard GSM04.08 and the 3G TS 24.008, this method requires GMM to start a READY timer (active time) for each mobile subscriber, when active time was in active state, the mobile management state of GMM was in READY (activity) state.The travelling carriage that regulation is in active state must be initiated cell updating course after finishing cell reselection process, must initiate Routing Area Update process in the SGSN (Serving GPRS Support Node) or the Routing Area Update process between SGSN through border, route district the time.Like this, GMM can be accurate to the travelling carriage current location cell range in active state.When active time is in inactive state, the mobile management state of GMM will be in STANDBY (standby) state.The travelling carriage that regulation is in stand-by state is not initiated cell updating course after finishing cell reselection process, only must initiate Routing Area Update process in the SGSN or the Routing Area Update process between SGSN through border, route district the time.Like this, GMM can only be accurate to location of mobile station route district scope at stand-by state.In order to allow GMM accurately adjust the running status of active time, standard GSM04.08 and 3G TS 24.008 regulations when the LLC layer when whenever receiving a upstream data, will trigger primitive LLGMM-TRIGGER.ind notice GMM with GMM simultaneously, GMM receives that this primitive will restart active time.In the time range of between a network side and mobile subscriber, consulting, GMM does not receive signaling message and triggers primitive LLGMM-TRIGGER.ind message from the GMM of LLC, then GMM thinks that travelling carriage does not have upstream message for a long time, and location of mobile station is unknowable, and active time is overtime to be stopped.When GMM was in stand-by state, LLC carried out pending operation with GMM suspended primitive LLGMM-SUSPEND.req notice, and travelling carriage discharges traffic channel resource.When LLC in suspended state and when having downlink data to send, GMM carries out paging with GMM paging primitive LLGMM-PAGE.ind notice, behind the corresponding beep-page message of receiving from the mobile subscriber, trigger primitive LLGMM-TRIGGER.ind notice GMM with GMM, GMM will carry out recovery operation with LLGMM-RESUME.req primitive notice LLC.Above-mentioned flow chart of data processing requires LLC when whenever receiving a upstream data, all needs to use a LLGMM-TRIGGER.ind message informing GMM.Supposing the system is handled the data service at 2 general-purpose families simultaneously, and each user on average carries out the transmission of upstream data with the speed of 12 bag/seconds, and GMM handles load to the notification message of LLC upstream data will reach for 240,000 bag/seconds, and this is concerning GMM, and load is huge.Therefore, the high load capacity of the data notification message that reports handled to reduce the disposal ability of GMM, and make the serious bottleneck effect of whole gprs system generation mobile subscriber's signaling procedure.
Summary of the invention
Problem at above-mentioned prior art existence, the objective of the invention is to, the using method of active time in a kind of general wireless packet service system is provided, uses this method can reduce the processing load of GMM greatly, thereby further improve the processing capacity and the service quality of system.
For achieving the above object, the invention provides the using method of active time in a kind of general wireless packet service system, this method comprises:
(1) enter active state after GMM finishes mobile subscriber's access, notice LLC starts active time;
(2) LLC restarts active time after receiving mobile subscriber's upstream data, then described upstream data is sent to network layer;
(3) if LLC does not receive mobile subscriber's upstream data for a long time, make that active time is overtime to be stopped, LLC notice GMM enters stand-by state, and enters hang-up (SUSPEND) state;
(4) if the downlink data request that LLC receives network side in suspended state, this downlink data of buffer memory, notice GMM initiates paging;
(5) LLC that is in suspended state is after receiving mobile subscriber's page response, and notice GMM enters active state, restarts active time and the downlink data of buffer memory under the suspended state is sent to the mobile subscriber.
Adopt said method, LLC takes over the active time of GMM management get off, when receiving upstream data, active time is restarted at every turn, without frequent notifications GMM, but after active time is overtime, once notify, the interacting message amount between LLC and the GMM that makes reduces greatly, so the present invention can reduce the processing load of GMM greatly, thereby further improves the processing capacity and the service quality of gprs system.
