Description

Timer duration configuration method and system, GPRS service support node

technical field

The invention relates to the technical field of communication, in particular to a timer duration configuration method and system, and a GPRS service support node.

Background technique

In a mobile communication network, in order to save information such as the location of a mobile station (MS, Mobile Station), the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) organization has introduced the concept of Mobility Management (MM, Mobility Management), The information for MM is stored in the MM context, and is managed by the MS and the Serving GPRS Support Node (SGSN, Serving GPRS Support Node; GPRS, General Packet Radio Service). Wherein, the information for MM includes a GPRS Mobility Management (GMM) status for describing GPRS mobility management activity of the MS. The GMM state is divided into three different states, namely: the state not connected to the network, the state attached to the network, and the state of data transmission. The GMM state of the MS should be consistent with the GMM state of the MS stored in the SGSN. In different GMM states, the occupation and use of network resources by the MS and the SGSN are different.

The statuses of each GMM in the GPRS network and the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) network are respectively introduced below.

(1) In the GPRS network, the state not connected to the network is called the IDLE state, the state attached to the network is called the STANDBY state, and the state of data transmission is called the READY state.

Among them, in the IDLE state, the MS is not connected to the network, and there is no location and routing information about the MS in the SGSN. At this time, the network will not perform data paging and data transmission for the MS; in the STADNBY state, the MS has attached to the GPRS At this time, the SGSN only knows the routing area where the MS is located, but cannot accurately know the cell where the MS is located. Therefore, the data of the MS on the network side can only be delivered by paging, and the MS can only update the routing area when performing the routing area update process. In the READY state, the SGSN understands the location information of the MS accurately to the cell level. At this time, the SGSN no longer sends the downlink GPRS data through paging, but directly transmits the data to the cell where the MS is located, and the MS The SGSN will be notified when the cell update process and the routing area update process are executed.

In the GPRS network, the transition process of the GMM state of the MS is shown in Figure 1, and the transition process of the GMM state of the MS stored in the SGSN is shown in Figure 2, where:

1. When the MS has not completed the GPRS attach process, the MS is always in the IDLE state;

2. When the MS completes the GPRS attach process, the MS changes from the IDLE state to the READY state;

3. There is a READY timer in MS and SGSN respectively, which records the length of time that MS does not interact with the network. Each MS corresponds to a READY timer. MS stores its own READY timer, and SGSN also The duration of the READY timer of the MS is stored. The duration of the two READY timers should be consistent. The READY timer is used to trigger the MS to change from the READY state to the STANDBY state. In the READY state, if the READY timer times out for the MS, Then the MS changes from READY state to STANDBY state;

4. In the STANDBY state, if the MS sends a Logical Link Control Protocol Data Unit (LLC PDU, Logical Link Control Protocol Data Unit) to the SGSN, the MS changes its GMM state from the STANDBY state to the READY state. If the SGSN receives the MS SGSN will change the saved GMM state of the MS from STANDBY state to READY state;

5. In the READY state, after the MS completes the GPRS detachment process, the GMM state of the MS changes to the IDLE state. The GMM state of the MS is changed to the IDLE state;

6. In the STANDBY state, the SGSN starts the Mobile-Reachable timer to record the length of time the MS is in the STANDBY state. The Mobile-Reachable timer is used to trigger the MS to change from the STANDBY state to the IDLE state. In the STANDBY state, If the Mobile-Reachable timer expires for the MS, the SGSN will initiate an implicit detach process, and the SGSN will change the GMM state of the MS to the IDLE state. If the SGSN receives a cancel location message from the HLR, the SGSN will also Change the GMM state of the MS to IDLE state.

(2) In the UMTS network, the GMM state is specifically called the Packet Mobility Management (PMM, Packet Mobility Management) state, wherein the state not connected to the network is called the PMM-detached (DETACHED) state, and the state attached to the network is called It is the PMM-IDLE state, and the state of data transmission is called the PMM-connected (CONNECTED) state.

Among them, in the PMM-DETACHED state, the MS is not connected to the network, there is no information exchange between the MS and the SGSN, there is no location and routing information about the MS in the SGSN, and the MS is unreachable for the SGSN; in the PMM -In the IDLE state, the MS has attached to the network. At this time, the SGSN only knows the routing area where the MS is located. The network side can only send data to the MS through paging, and the MS can only perform the routing area update process. The SGSN is notified; in the PMM-CONNECTED state, a packet switching (PS, Packet Switching) signaling connection is established between the MS and the SGSN, and the SGSN's understanding of the MS location information is accurate to the Radio Network Controller (RNC, Radio Network Controller) At this time, the SGSN directly transmits the downlink GPRS data to the RNC where the MS is located.

In the UMTS network, the transition process of the PMM state of the MS and the transition process of the PMM state of the MS stored in the SGSN are shown in Figure 3, where:

1. When the MS has not completed the GPRS attachment process, the MS is always in the PMM-DETACHED state;

2. When the MS completes the GPRS attach process, a PS signaling connection is established between the MS and the SGSN. At the same time, the MS and the SGSN will generate an MM context, and the PMM state of the MS will change to the PMM-CONNECTED state;

3. There is a T3319 timer in MS and SGSN respectively, which records the length of time that MS does not interact with the network. Each MS corresponds to a T3319 timer duration. MS stores its own T3319 timer duration, and SGSN also The duration of the T3319 timer of the MS is stored. The duration of the two T3319 timers should be consistent. The T3319 timer of the MS is used to trigger the MS to change from the PMM-DETACHED state to the PMM-IDLE state. In the PMM-DETACHED state, if T3319 When the timer expires for the MS, the MS changes to the PMM-IDLE state. In addition, in the PMM-DETACHED state, if the PS signaling connection release process is completed, the MS changes to the PMM-IDLE state;

4. In the PMM-CONNECTED state, when the MS performs GPRS detachment, the routing area update is rejected, and the GPRS attach is rejected, the PS signaling connection and MM context will be deleted, and the PMM state of the MS will change to PMM-DETACHED state;

5. In the PMM-IDLE state, if the PS signaling connection establishment operation is completed, the PMM state of the MS is changed to the PMM-CONNECTED state;

6. In the PMM-IDLE state, if the MS directly pulls out the battery or subscriber module (such as a Subscriber Identity Module (SIM, Subscriber Identity Module) card or a Universal Subscriber Identity Module (USIM, Universal Subscriber Identity Module) card) when the MS is turned on, the MS The implicit detach process will be initiated, and the PMM state of the MS will change to the PMM-DETACHED state. In the PMM-IDLE state, the SGSN will start the Mobile-Reachable timer. If the Mobile-Reachable timer expires for the MS, the implicit In the detach operation, the MM context and the Packet Data Protocol (PDP, Packet Data Protocol) context are deleted, and the PMM state of the MS is changed to the PMM-DETACHED state.

In order to save network resources, 3GPP stipulates that after the MS is connected to the network, if it does not interact with the network for a period of time, the MS will be changed from the state of data transmission to the state of being attached to the network. Among them, the MS does not perform data interaction with the network. The time length is limited by the MS READY timer duration/T3319 timer duration. The duration of the READY timers of all MSs is the same, the duration of the T3319 timers of all MSs is the same, the default value of the duration of the READY timer is 44 seconds, and the default value of the duration of the T3319 timer is 30 seconds. In the prior art, the SGSN can only configure the READY timer duration/T3319 timer duration of the MS through an attach success message or a route update success message.

It can be seen from the above that in the prior art, the SGSN configures the same READY timer duration/T3319 timer duration for all MSs in the prior art. If the READY timer duration/T3319 timer duration is configured too small, some MSs that frequently use services will If the state of data transmission is changed frequently to the state of being attached to the network, the network will often initiate paging to these MSs, which consumes a lot of network processing resources and brings a large load to the network; if the READY timer duration/ If the T3319 timer is configured too long, some MSs that rarely use services will change from the state of data transmission to the state of being attached to the network after a long time. It will occupy network resources for a long time. The inventor believes that in the prior art, it is difficult to reasonably configure the READY timer duration/T3319 timer duration of the MS, which will consume a large amount of network processing resources and bring a large load to the network.

Contents of the invention

The technical scheme of the embodiment of the present invention is as follows:

A timer duration configuration method, the method comprising the steps: GPRS service support node SGSN determines the frequency of access to the network by a mobile station MS; judging whether the determined frequency satisfies a preset configuration condition; and when the judging result is yes , according to the determined frequency, configure the duration of the first timer of the MS, and the first timer is used to trigger the GPRS mobility management GMM state of the MS to change from the state of data transmission to the state of attaching to the network .

A timer duration configuration system, including: GPRS service support node SGSN and mobile station MS, wherein: the SGSN is used to determine the frequency of the MS accessing the network, and determine whether the determined frequency meets the preset configuration conditions, and when the judgment result is yes, configure the first timer duration of the MS according to the determined frequency, and the first timer is used to trigger the GPRS mobility management GMM state of the MS by data The state of transmission is changed to the state of being attached to the network; the MS is configured to update the duration of the first timer saved by itself according to the duration of the first timer configured by the SGSN.

It can be seen from the above that the technical solution of the embodiment of the present invention can reasonably configure the first timer duration of each MS. The SGSN no longer configures the same first timer duration for all MSs, but for each MS, according to the MS The frequency of accessing the network configures the duration of the first timer of the MS, so the duration of the first timer of the MS corresponds to the frequency of the MS accessing the network. ) The configured first timer duration is different from the first timer duration configured for MSs that do not frequently use services (that is, MSs that access the network infrequently), so frequent state changes caused by data transmission for MSs that frequently use services can be avoided Due to the state of being attached to the network and the problem that MSs that do not frequently use services still occupy network resources for a long time when they do not need to access the network, this effectively saves network processing resources and reduces network load.

detailed description

Embodiment one

As shown in Figure 4, it is a flowchart of the timer duration configuration method proposed in Embodiment 1 of the present invention, and its specific processing process is as follows:

In step 41, the SGSN determines the frequency of the MS's access to the network.

In Embodiment 1 of the present invention, the SGSN may, but not be limited to, include the following two methods for determining the frequency of the MS accessing the network:

The first way to determine the frequency is that the SGSN obtains the number of times that the MS changes between the state of attaching to the network and the state of data transmission within a specified period of time when the GMM state is the preset state, and uses the obtained number of times , which is determined as the frequency of the MS accessing the network. Wherein, the preset state is the state of being attached to the network or the state of data transmission, and the greater the number of times the MS changes from the state of being attached to the network to the state of data transmission, it indicates that the MS visits the network more frequently.

The number of changes between the state attached to the network and the state of data transmission includes: the number of times the state is changed from the state attached to the network to the state of data transmission, and/or the number of times the state is changed from the state of data transmission to the state attached to the network . That is to say, the number of changes between the state attached to the network and the state of data transmission can be only the number of times the state of being attached to the network is changed to the state of data transmission, or only the state of data transmission can be changed to attached. The number of times to the state of the network may also be the number of times of changing from the state of being attached to the network to the state of data transmission and the number of times of changing from the state of data transmission to the state of being attached to the network. For the convenience of description, the following descriptions of the embodiments of the present invention take the number of changes between the state attached to the network and the state of data transmission as an example for illustration.

The second way to determine the frequency is that the SGSN obtains the length of time that the MS is in the state of being attached to the network before the GMM state changes from the state of being attached to the network to the state of data transmission, and the obtained time length is used to represent the The frequency of the MS accessing the network is described above, wherein the shorter the time length of the MS being attached to the network, the more frequent the MS accessing the network.

Among them, in the GPRS network, the state not connected to the network is called the IDLE state, the state attached to the network is called the STANDBY state, and the state of data transmission is called the READY state. In the UMTS network, the state not connected to the network is called the PMM- The DETACHED state, the state attached to the network is called the PMM-IDLE state, and the state of data transmission is called the PMM-CONNECTED state.

In the above-mentioned first method of determining the frequency, the SGSN can set a third timer (hereinafter referred to as T1 timer) and a counter (hereinafter referred to as Counter), and set the duration of the T1 timer to a preset specified time length (such as 30 minutes), the Counter is used to record that within the time limit limited by the T1 timer, the MS changes from the state attached to the network (hereinafter referred to as STANDBY state/PMM-IDLE state) to the state of data transmission (hereinafter referred to as READY state/ PMM-CONNECTED state) times. If the MS changes from the state of not connected to the network (hereinafter referred to as the IDLE state/PMM-DETACHED state) to the READY state/PMM-CONNECTED state, then the SGSN starts the T1 timer to count the MS. (that is, the above-mentioned specified time length), if the MS changes from the STANDBY state/PMM-IDLE state to the READY state/PMM-CONNECTED state, the Counter is cumulatively incremented by one for the MS, and if the T1 timer is timed out for the MS, Then the SGSN counts the counting result of the Counter for the MS, and the counting result is that the GMM state of the MS is the preset state (attached to the network state or data transmission state) within the specified time length, by the MS attached to the network The number of times the state changed to the state of data transfer.

In the above-mentioned second way of determining the frequency, when the SGSN changes the GMM state of the MS from the STANDBY state/PMM-IDLE state to the READY state/PMM-CONNECTED state, the second timer confirms the counting length of the MS as The length of time that the MS is in the STANDBY state/PMM-IDLE state, wherein the second timer can be, but not limited to, a Mobile-Reachable timer, which is used to trigger the GMM state of the MS to change from the STANDBY state/PMM-IDLE state to the READY state /PMM-CONNECTED state. Among them, the GMM state of the MS changes from the STANDBY state/PMM-IDLE state to the READY state/PMM-CONNECTED state in the following two situations:

Case 1: When the MS is in the STANDBY state/PMM-IDLE state, the SGSN receives the LLC PDU/service request sent by the MS, and then changes the saved GMM state of the MS to the READY state/PMM-CONNECTED state;

Case 2: When the MS is in the STANDBY state/PMM-IDLE state, the Mobile-Reachable timer for the MS times out, and the SGSN changes the saved GMM state of the MS to the READY state/PMM-CONNECTED state.

Step 42, judging whether the frequency determined in step 41 satisfies a preset configuration condition.

For the above-mentioned first method of determining the frequency, the SGSN confirms the acquired frequency as the frequency of the MS accessing the network, and then the SGSN judges whether the acquired frequency is greater than the preset upper limit threshold, and whether it is less than the preset The lower limit threshold of the number of times. If it is determined that the obtained number of times is greater than the preset upper limit threshold or less than the preset lower limit threshold, it is confirmed that the frequency of the MS's access to the network meets the preset configuration conditions; otherwise, it is confirmed that the frequency of the MS's access to the network The frequency does not meet the preset configuration conditions.

Wherein, the counting result of the Counter is set in advance with an upper limit threshold and a lower limit threshold, which are used to limit whether to trigger a configuration operation on the duration of the first timer. If the counting result obtained by the SGSN statistics is greater than the upper limit threshold or less than the lower threshold threshold, it is confirmed that the configuration condition is met, so the configuration operation for the first timer duration can be triggered; if the counting result obtained by the SGSN statistics is not greater than the upper limit threshold, and If it is not less than the lower limit threshold of the number of times, it is confirmed that the configuration condition is not met, so there is no need to trigger the configuration operation of the first timer duration.

For the above-mentioned second method of determining the frequency, the time length obtained by the SGSN is used to represent the frequency of the MS accessing the network, and the SGSN judges whether the obtained time length is greater than the preset time length upper limit threshold, and whether it is less than the preset time length If it is judged that the obtained time length is greater than the preset time length upper limit threshold or less than the preset time length lower limit threshold, then confirm that the frequency of the MS accessing the network meets the preset configuration conditions, otherwise confirm The frequency with which the MS accesses the network does not meet the preset configuration condition.

Wherein, for the timing length of the second timer (hereinafter referred to as the Mobile-Reachable timer), a lower threshold of the duration and an upper threshold of the duration are set in advance to limit whether to trigger the configuration operation of the duration of the first timer. If the timing length of the Mobile-Reachable timer is greater than the upper threshold or lower than the lower threshold, the configuration condition is confirmed to be met, so the configuration operation for the first timer duration can be triggered. If the timing length of the Mobile-Reachable timer is not If it is greater than the upper limit threshold of the time length and not less than the lower limit threshold of the time length, it is confirmed that the configuration condition is not satisfied, and therefore, the configuration operation of the first timer duration does not need to be triggered.

Step 43, when the judgment result is yes, according to the determined frequency, configure the duration of the first timer of the MS, and the first timer is used to trigger the GMM state of the MS to change from the state of data transmission to attached to the state of the network.

Wherein, the above-mentioned first timer may be the READY timer/T3319 timer, then the duration of the first timer of the MS is the duration of the READY timer/the duration of the T3319 timer.

For the above-mentioned first method of determining the frequency, if the SGSN confirms that the configuration conditions are satisfied, the SGSN triggers the configuration operation of the first timer duration (hereinafter referred to as the READY timer duration/T3319 timer duration), at this time, if the SGSN acquires If the number of arrival times is greater than the preset upper limit threshold, it indicates that the MS interacts frequently with the network within the specified time period, and it is necessary to increase the READY timer duration/T3319 timer duration appropriately. length (for example, it can be set to 5 seconds), increase the READY timer duration of the MS/T3319 timer duration; if the number of times acquired by the SGSN is less than the preset lower limit threshold, it indicates that the MS is within the above-mentioned specified time length. Network interaction is infrequent, and it is necessary to appropriately shorten the READY timer duration/T3319 timer duration, so the SGSN reduces the READY timer duration/T3319 timer duration of the MS based on a preset adjustment step (for example, it can be set to 5 seconds). duration.

In addition, in order to prevent the READY timer duration/T3319 timer duration of the MS from being too large or too small, Embodiment 1 of the present invention proposes that the duration upper limit threshold and the duration lower threshold can be set for the READY timer duration/T3319 timer duration in advance. The modification of the READY timer duration/T3319 timer duration cannot exceed these two thresholds. Therefore, before increasing the READY timer duration/T3319 timer duration of the MS based on the preset adjustment step, the SGSN can first determine whether the current READY timer duration/T3319 timer of the MS is less than the preset upper limit threshold. If the judgment result is yes, execute the step of increasing the MS READY timer duration/T3319 timer duration based on the preset adjustment step; otherwise, do not configure the MS READY timer duration/T3319 timer duration. Before reducing the READY timer duration/T3319 timer duration of the MS based on the preset adjustment step, the SGSN may first determine whether the MS's current READY timer duration/T3319 timer duration is greater than the preset lower limit threshold , if the judgment result is yes, perform the step of reducing the MS READY timer duration/T3319 timer duration based on the preset adjustment step, otherwise, do not configure the MS READY timer duration/T3319 timer duration.

Specifically, if the counting result obtained by the SGSN statistics is greater than the upper limit threshold, and the MS's current READY timer duration/T3319 timer duration is less than the preset duration upper threshold, the SGSN increases the MS's count based on the preset adjustment step size. READY timer duration/T3319 timer duration; if the counting result obtained by SGSN statistics is less than the lower limit threshold of times, and the current MS READY timer duration/T3319 timer duration is greater than the preset duration lower limit threshold, SGSN adjusts based on the preset The step size is to reduce the MS READY timer duration/T3319 timer duration.

For the above-mentioned second way of determining the frequency, if the SGSN confirms that the configuration conditions are met, the SGSN triggers the configuration operation of the READY timer duration/T3319 timer duration, because the time length in the STANDBY state/PMM-IDLE state is the MS in the The time length of the inactive state. Therefore, if the above-mentioned time length of the STANDBY state/PMM-IDLE state acquired by the SGSN is greater than the preset time length upper threshold, it indicates that the MS has not interacted with the network within the above-mentioned specified time length. Frequently, it is necessary to appropriately reduce the READY timer duration/T3319 timer duration, so the SGSN reduces the READY timer duration/T3319 timer duration of the MS based on the preset adjustment step; The time length of the /PMM-IDLE state is less than the preset time length lower limit threshold, indicating that the MS interacts frequently with the network within the above-mentioned specified time length, and it is necessary to increase the READY timer length/T3319 timer length appropriately, so the SGSN Based on the preset adjustment step, increase the duration of the MS's READY timer/the duration of the T3319 timer.

In addition, in order to prevent the READY timer duration/T3319 timer duration of the MS from being too large or too small, Embodiment 1 of the present invention proposes that the duration upper limit threshold and the duration lower threshold can be set for the READY timer duration/T3319 timer duration in advance. The modification of the READY timer duration/T3319 timer duration cannot exceed these two thresholds. Therefore, before reducing the READY timer duration/T3319 timer duration of the MS based on the preset adjustment step, the SGSN can first determine whether the current READY timer duration/T3319 timer of the MS is greater than the preset lower limit threshold. If the judgment result is yes, perform the step of reducing the MS READY timer duration/T3319 timer duration based on the preset adjustment step, otherwise, do not configure the MS READY timer duration/T3319 timer duration. Before increasing the READY timer duration/T3319 timer duration of the MS based on the preset adjustment step, the SGSN may first determine whether the current READY timer duration/T3319 timer duration of the MS is less than the preset upper limit threshold , if the judgment result is yes, execute the step of increasing the MS READY timer duration/T3319 timer duration based on the preset adjustment step, otherwise, do not configure the MS READY timer duration/T3319 timer duration.

Specifically, if the timing length of the Mobile-Reachable timer is greater than the upper limit threshold of the time length, and the MS's current READY timer duration/T3319 timer duration is greater than the preset lower limit threshold, the SGSN will reduce the The duration of the READY timer of the small MS/the duration of the T3319 timer; if the duration of the Mobile-Reachable timer is less than the upper threshold of the duration, and the duration of the current READY timer of the MS/the duration of the T3319 timer is smaller than the preset upper threshold, then Based on the preset adjustment step, the SGSN increases the duration of the MS's READY timer/the duration of the T3319 timer.

For the above-mentioned second method of determining the frequency, Embodiment 1 of the present invention proposes that the SGSN can monitor the timing length of the Mobile-Reachable timer for the MS in real time. If the timing of the Mobile-Reachable timer for the MS has not timed out, but the SGSN receives The LLC PDU/service request sent by the MS, the GMM state of the MS changes from the STANDBY state/PMM-IDLE state to the READY state/PMM-CONNECTED state. Set the upper limit threshold of the time length and whether it is less than the preset lower limit threshold of the time length, and perform subsequent configuration operations; in addition, when the SGSN monitors the timing length of the Mobile-Reachable timer for the MS in real time, if the Mobile-Reachable timer for the MS If the timing has not timed out, but the duration of the Mobile-Reachable timer for the MS has exceeded the preset upper threshold, the SGSN can perform subsequent configuration operations.

In Embodiment 1 of the present invention, when the SGSN configures the READY timer duration/T3319 timer duration of the MS, it can first configure the READY timer duration/T3319 timer duration of the MS saved by itself, and then configure the MS READY timer duration/T3319 timer duration. The READY timer duration/T3319 timer duration is notified to the MS, instructing the MS to update the READY timer duration/T3319 timer duration saved by itself. Wherein, the SGSN can notify the MS of the configured READY timer duration/T3319 timer duration through existing signaling or dedicated signaling in the live network.

In the prior art, the SGSN can only configure the READY timer duration/T3319 timer duration of the MS through an attach success message or a route update success message, so the configuration may not be timely. However, in Embodiment 1 of the present application, the SGSN can dynamically configure the duration of the READY timer/T3319 timer flexibly, thus avoiding the problem of untimely configuration in the prior art and effectively improving configuration flexibility.

It can be seen from the above process that in the technical solution of the embodiment of the present invention, the SGSN first determines the frequency of MS accessing the network, and then when the determined frequency meets the preset configuration conditions, the MS's first A timer duration is configured, wherein the first timer is used to trigger the GMM state of the MS to change from the state of data transmission to the state of being attached to the network. It can be seen from the above that the technical solution of the embodiment of the present invention can reasonably configure the first timer duration of each MS. The SGSN no longer configures the same first timer duration for all MSs, but for each MS, according to the MS The frequency of accessing the network configures the duration of the first timer of the MS, so the duration of the first timer of the MS corresponds to the frequency of the MS accessing the network. ) The configured first timer duration is different from the first timer duration configured for MSs that do not frequently use services (that is, MSs that access the network infrequently), so frequent state changes caused by data transmission for MSs that frequently use services can be avoided Due to the state of being attached to the network and the problem that MSs that do not frequently use services still occupy network resources for a long time when they do not need to access the network, this effectively saves network processing resources and reduces network load.

The following describes in detail how the SGSN configures the READY timer duration/T3319 timer duration according to the number of times the MS changes from the STANDBY state/PMM-IDLE state to the READY state/PMM-CONNECTED state.

Embodiment two

As shown in FIG. 5 , it is the process of configuring the READY timer duration/T3319 timer duration by the SGSN according to the number of times the MS changes from the STANDBY state/PMM-IDLE state to the READY state/PMM-CONNECTED state in the second embodiment of the present invention. Schematic diagram, the specific processing flow is as follows:

Step 51, when the MS is in the IDLE state/PMM-DETACHED state, if the attachment is successful and the PDP context is activated, the MS changes from the IDLE state/PMM-DETACHED state to the READY state/PMM-CONNECTED state;

Step 52, the SGSN activates the T1 timer to count the MS, activates the READY timer/T3319 timer to count the MS, and activates the Counter to count the MS;

Step 53, the SGSN judges whether the T1 timer is timed out for the MS, if the judgment result is yes, then go to step 54, if the judgment result is no, then go to step 57;

Step 54, the SGSN stops the T1 timer from counting the MS, and stops the Counter from counting the MS;

Step 55, configure the READY timer duration/T3319 timer duration of the MS according to the counting result of the Counter;

Specifically: if the counting result of the Counter is greater than the preset upper limit threshold, and the MS's current READY timer duration/T3319 timer duration is less than the preset duration upper threshold, then based on the preset adjustment step, increase the MS's READY timer duration/T3319 timer duration; if the count result of Counter is less than the preset lower limit threshold, and the MS's current READY timer duration/T3319 timer duration is greater than the preset duration lower threshold, based on the preset Set the adjustment step to reduce the READY timer duration of the MS/T3319 timer duration.

Step 56, refresh the T1 timer to re-time the MS and refresh the Counter to re-count the MS, and then go to step 53;

Step 57, if the READY timer/T3319 timer has not timed out for the MS, and the SGSN receives the LLC PDU/PDU sent by the MS, the SGSN refreshes the READY timer/T3319 timer to time the MS again;

Step 58, if the READY timer/T3319 timer times out for the MS, the MS changes from the READY state/PMM-CONNECTED state to the STANDBY state/PMM-IDLE state;

Step 59, when the MS is in the STANDBY state/PMM-IDLE state, the SGSN receives the LLC PDU/service request sent by the MS, then the MS changes from the STANDBY state/PMM-IDLE state to the READY state/PMM-CONNECTED state, and the Counter for The MS is incremented by one, and then go to step 53 .

As shown in Figure 6, for the second embodiment of the present invention, when in the GPRS network, the SGSN changes the number of times from the STANDBY state to the READY state according to the MS, and configures the flow diagram of the READY timer duration, and its specific processing flow is as follows:

Step 61, when the MS is in the IDLE state, if the attachment is successful and the PDP context is activated, the MS changes from the IDLE state to the READY state;

Step 62, the SGSN activates the T1 timer to count the MS, activates the READY timer to count the MS, and activates the Counter to count the MS;

Step 63, if the READY timer has not timed out for the MS, and the SGSN receives the LLC PDU sent by the MS, the SGSN refreshes the READY timer to re-time the MS;

Step 64, if the READY timer times out for the MS, the MS changes from the READY state to the STANDBY state;

Step 65, when the MS is in the STANDBY state, the SGSN receives the LLC PDU sent by the MS, then the MS changes from the STANDBY state to the READY state, and the Counter accumulates one for the MS, and starts the READY timer to time the MS again;

Step 66, if the T1 timer times out for the MS, the SGSN stops the T1 timer for the MS and stops the Counter for counting the MS;

Step 67, configure the duration of the READY timer of the MS according to the counting result of the Counter;

Specifically: if the counting result of the Counter is greater than the preset upper threshold, and the current READY timer duration of the MS is less than the preset upper threshold, it indicates that the MS interacts frequently with the network, and the READY timer needs to be appropriately increased Therefore, the SGSN increases the READY timer duration of the MS based on the preset adjustment step; if the count result of the Counter is less than the preset lower limit threshold, and the current READY timer duration of the MS is greater than the preset lower limit threshold, it indicates that the interaction between the MS and the network is infrequent, and the duration of the READY timer needs to be appropriately reduced. Therefore, the SGSN reduces the duration of the MS's READY timer based on the preset adjustment step.

In step 68, the MS notifies the MS of the modified READY timer duration, instructs the MS to update the READY timer duration saved by itself, then refreshes the Counter to recount the MS, and refreshes the T1 timer to recount the MS.

As shown in Fig. 7, in the second embodiment of the present invention, when in the UMTS network, the SGSN configures the duration of the T3319 timer according to the number of times the MS changes from the PMM-IDLE state to the PMM-CONNECTED state. The processing flow is as follows:

Step 71, when the MS is in the PMM-DETACHED state, if the attachment is successful and the PDP context is activated, the MS changes from the PMM-DETACHED state to the PMM-CONNECTED state;

Step 72, the SGSN activates the T1 timer to count the MS, activates the T3319 timer to count the MS, and activates the Counter to count the MS;

Step 73, if the T3319 timer has not timed out for the MS, and the SGSN receives the PDU sent by the MS, the SGSN refreshes the T3319 timer to re-time the MS;

Step 74, if the T3319 timer expires for the MS, the MS requests to delete the PS signaling connection with the SGSN, and after the PS signaling connection is deleted, the MS changes from the PMM-CONNECTED state to the PMM-IDLE state;

Step 75, when the MS is in the PMM-IDLE state, the SGSN receives the service request sent by the MS, then a PS signaling connection is established between the SGSN and the MS, the MS is changed from the PMM-IDLE state to the PMM-CONNECTED state, and the Counter is for The MS accumulates one, and starts the T3319 timer to time the MS again;

Step 76, if the T1 timer times out for the MS, the SGSN stops the T1 timer for the MS and stops the Counter for counting the MS;

Step 77, configure the T3319 timer duration of the MS according to the counting result of the Counter;

Specifically: if the counting result of the Counter is greater than the preset upper threshold, and the current T3319 timer duration of the MS is less than the preset upper threshold, it indicates that the MS interacts frequently with the network, and the T3319 timer needs to be appropriately increased Therefore, the SGSN increases the T3319 timer duration of the MS based on the preset adjustment step; if the count result of the Counter is less than the preset lower limit threshold, and the current T3319 timer duration of the MS is greater than the preset lower limit threshold, it indicates that the MS interacts with the network infrequently, and the duration of the T3319 timer needs to be appropriately reduced. Therefore, the SGSN reduces the duration of the MS's T3319 timer based on the preset adjustment step.

Step 78, the MS notifies the MS of the modified T3319 timer duration, instructs the MS to update the READY timer duration saved by itself, and then refreshes the Counter to recount for the MS, and refreshes the T1 timer to recount for the MS.
