Description

Network optimization method, device and system based on intelligent terminal

Technical field

The present invention relates to the field of communications technologies, and in particular, to a network optimization method, device, and system based on an intelligent terminal.

Background technique

At present, the proportion of smart terminals in mobile terminals has risen sharply, which has driven the trend of global smart terminals. Compared with the common terminals that have been widely used at present, the intelligent terminal has the following typical characteristics:

(1) Always-on applications: Smart terminals need to provide always-on services for certain applications running on them, such as QQ, MSN and Twitter. These instant messaging applications send some online updates to the network every few seconds. Message

(2) High-frequency air interface signaling connection re-establishment and re-activation of the Packet Data Protocol (PDP) context.

(3) Always try 3G network access and frequent 2G/3G network switching: In the overlapping coverage area of 2G and 3G networks, if the 3G network access fails, the intelligent terminal will try to access the 2G network, but even the 2G network access Successfully, intelligent terminals always try 3G network access.

(4) Fast Dormancy mode: In order to save battery power, the intelligent terminal will forcibly switch to the fast sleep mode when it detects that there is no data transmission.

(5) Intelligent terminal applications are frequently used: Intelligent terminals support applications such as web browsing, timely communication, email, and geographic location-based services, which generate high-frequency, small-stream data transmission.

In the prior art, the network side adopts a processing method consistent with the ordinary terminal for the smart terminal. With the large-scale use of intelligent terminals, the ability of intelligent terminals to occupy network resources greatly exceeds that of ordinary terminals. Due to the above characteristics of the intelligent terminal, the data and signaling load of the mobile network is greatly increased. The always-on and high-frequency use of smart terminal applications generates a large amount of data traffic. According to statistics, 3% of intelligent terminals generate 40% of the data traffic of the entire network. In addition, frequent air interface signaling connection reestablishment and PDP context reactivation and frequent 2G/3G network switching of intelligent terminals generate excessive signaling traffic compared to ordinary terminals. According to the data, the signaling traffic of the intelligent terminal is 14 times that of the ordinary terminal when the same data is transmitted. Due to the limited signaling capacity originally planned by the network, additional signaling load can easily lead to dropped calls, inaccessibility, network congestion, etc. In the absence of congestion processing methods for network congestion caused by intelligent terminals, the network side recovers after congestion occurs, which affects the provision of normal services for ordinary terminals.

In the embodiment of the present invention, there are various implementation methods for identifying the smart terminal, which are described in detail below by way of examples.

Example 1 In this embodiment, after the terminal is successfully attached to the network, the mobility management network element counts the number of service requests initiated by the terminal in a certain period, such as the first predetermined period. If the number of service requests exceeds the preset first threshold F1 in the period, the mobility management network element determines that the terminal is an intelligent terminal, and sends corresponding indication information to the access network element and the gateway network element to enable the connection. The incoming network element and the gateway network element perform optimization processing for the smart terminal. Further, after determining that the terminal is an intelligent terminal, if the number of service requests initiated by the smart terminal does not exceed the first threshold F1 in the first F2 consecutive first predetermined periods, the access network is The element and the gateway network element send corresponding indication information, so that the access network element and the gateway network element cancel the optimization process for the smart terminal.

In a specific implementation, the mobility management network element may be configured with an intelligent terminal identifier. After the mobility management network element determines that the terminal is an intelligent terminal, the smart terminal identifier is set to true, and the identifier is sent to the gateway network. The element and the access network element are configured to enable the gateway network element and the access network element to perform optimization processing of the intelligent terminal.

As shown in FIG. 2, it is a specific implementation flowchart of identifying an intelligent terminal in the embodiment of the present invention, which mainly includes the following steps:

201. The terminal successfully initiates the attach process.

202. After the terminal successfully registers with the network, the mobility management network element sets the smart terminal identifier to false, clears the service request message counter, and starts the first timer.

203. The terminal in the idle state sends a service request message to the mobility management network element. The triggering of the message may be that the terminal has uplink data to be sent, or receives a paging message sent by the access network element.

204. After receiving the service request message, the mobility management network element adds the service request message counter 1 . And determine whether the service request message counter value is greater than the threshold F1. If it is greater than the threshold F1, the mobility management network element sets the smart terminal identifier to true and triggers steps 205 and 206.

The mobility management network element sends the first indication information to the gateway network element and the access network element, so that the gateway network element and the access network element respectively perform optimization processing for the smart terminal. The first indication information may be an intelligent final energy identifier, and may be other information, as long as the gateway network element and the access network element can identify that the first indication information is used to indicate that the optimization processing for the smart terminal is performed. Information can be.

The first indication information may be carried in a GPRS Tunneling Protocol (GTP) message, and a field may be added to the GTP message, or an existing field may be used to indicate that the optimized processing for the smart terminal is performed.

209. After receiving the service request message, the mobility management network element increments the service request message counter by one. If the first timer expires, the mobility management network element determines whether the service request message counter value is greater than the threshold F1. If it is greater than the threshold F1, the mobility management network element clears the service request message counter and the exit counter, and restarts the first timer; otherwise, the mobility management network element clears the service request message counter, and increments the exit counter by one, and Restart the first timer. If the exit counter value is greater than the threshold F2, it indicates that the number of service request messages initiated by the terminal does not exceed the threshold F1 in consecutive F2 periods. The mobility management network element sets the smart terminal identifier to false. If the smart terminal identifier changes from true to false, steps 210 and 211 are triggered.

210a, 210b. The mobility management network element sends the second indication information to the gateway network element and the access network element, so that the gateway network element and the access network element respectively cancel the optimization processing for the smart terminal. The second indication information may be an intelligent final energy identifier, and may be other information, as long as the gateway network element and the access network element can identify that the second indication information is used to indicate that the optimization processing for the smart terminal is cancelled. Information can be.

211a, 210b. The gateway network element and the access network element respectively cancel the optimization processing for the smart terminal. It should be noted that, since the smart terminal initiates a service request, there may be a busy period and a idle period, so the above steps 203 to 211 may be repeated multiple times.

Example 2. In this embodiment, the mobility management network element establishes IMEISV (International Mobile

In the attaching process initiated by the terminal, the mobility management network element acquires the IMEISV of the terminal, and identifies the smart terminal according to the matching relationship between the IMEISV and the smart terminal model, and sends corresponding indication information to the access network element and the gateway network element. The access network element and the gateway network element perform optimization processing for the smart terminal.

As shown in FIG. 3, it is another specific implementation flowchart for identifying an intelligent terminal in the embodiment of the present invention, which mainly includes the following steps:

301. The mobility management network element establishes a matching relationship between the IMEISV and the terminal model.

Information can be.

306a, 306b. After receiving the indication information, the gateway network element and the access network element respectively perform optimization processing of the smart terminal.

Example 3: In this embodiment, after the terminal is successfully attached to the network, the mobility management network element records the time of the PDP (Packet Data Protocol) context activation, and calculates a PDP context in a certain period, such as a second predetermined period. The ratio of activation time to attachment time. If the time ratio exceeds the preset third threshold F3 in the period, the corresponding indication information is sent to the access network element and the gateway network element, The access network element and the gateway network element perform optimization processing for the smart terminal.

Further, after determining that the terminal is an intelligent terminal, if the PDP context activation time and the attachment time ratio do not exceed the third threshold F3 in consecutive F2 of the second predetermined periods, then accessing the network element and The gateway network element sends corresponding indication information, so that the access network element and the gateway network element cancel the optimization processing for the smart terminal.

Similarly, in a specific implementation, an intelligent terminal identifier may be set. After the mobility management network element determines that the terminal is an intelligent terminal, the smart terminal identifier is set to true, and the identifier is sent to the gateway network element and connected. The network element is added to enable the gateway network element and the access network element to perform optimization processing of the intelligent terminal.

As shown in FIG. 4, it is another specific implementation flowchart for identifying an intelligent terminal in the embodiment of the present invention, which mainly includes the following steps:

401. The terminal successfully registered to the network.

402. After the terminal successfully registers with the network, the mobility management network element sets the smart terminal identifier to false, records the system initial time to calculate the attachment time, and starts the second timer.

403. The terminal initiates a PDP context activation request to the network side to activate the PDP context.

404. After the terminal successfully activates the PDP context, the mobility management network element starts a PDP context activation timer.

405. The terminal initiates a PDP context deactivation request to the network side to deactivate the PDP context.

406. After all PDP contexts are successfully deactivated, the mobility management network element suspends the PDP context activation timer.

407. If the second timer expires, the mobility management network element calculates a PDP context activation time and an attached time ratio, determines whether the time ratio is greater than a threshold F3, and restarts the second timer. If the time ratio is greater than the threshold F3, the mobility management network element sets the smart terminal identifier to true and clears the exit counter; otherwise, the mobility management network element increments the exit counter by one; if the exit counter value is greater than the threshold F2, the mobility management network element sets the smart terminal identifier to false. If the smart terminal identifier is true, steps 408 and 409 are triggered; if the smart terminal identifier changes from true to false, steps 410 and 411 are triggered.

411. The gateway network element and the access network element respectively cancel the optimization processing for the smart terminal.

It should be noted that, in this embodiment, if the mobility management network element changes, the new mobility management network element re-records the system time to calculate the attachment time, stops and restarts the second timer, clears the exit counter, and resets. PDP context activation timer.

In addition, since the terminal may activate the PDP context multiple times and deactivate all PDP contexts, the above steps 403 to 407 may be repeated multiple times.

It should be noted that the foregoing various thresholds and periods may be determined according to actual application requirements. The re-election process or the handover process may occur due to the mobility of the terminal. Therefore, in order to further improve the optimization efficiency, in the embodiment of the present invention shown in FIG. 1, the method may further include the following steps: Then, the first indication information is sent to the target side mobility management network element. specifically:

In the attaching process, the primary mobility management network element receives the identity identification request message sent by the target mobility management network element; after identifying that the terminal is an intelligent terminal, the primary mobility management network element may pass the identity The response message identifying the request message sends the first indication information to the target side mobility management network element.

And after the identification of the terminal as an intelligent terminal, the primary mobility management network element may send the first indication information to the target mobility management network element by using the relocation request message.

Of course, for the smart terminal, when the corresponding optimization process needs to be canceled, the original mobility management network element may also send the second indication information to the target mobility management network element in the foregoing manner.

In addition, in the embodiment of the present invention, the target side mobility management network element may also be notified in other manners. For example, after the primary mobility management network element identifies that the terminal is an intelligent terminal, the first indication information is inserted into the subscription database, so that the target-side mobility management network element can obtain the subscription data. The first indication information is obtained in the library. Of course, for the smart terminal, in the need to cancel the corresponding preferential subscription database, the target-side mobility management network element obtains the second indication information from the subscription database.

In a specific application, the first indication message and the second indication message may be the aforementioned smart terminal identifier and its current value.

In addition, in the embodiment of the present invention, after the terminal that identifies the access network is the smart terminal, the mobility management network element may also send the first indication information to the subscription database, so that the subscription database performs the smart Optimized processing of the terminal.

In the embodiment of the present invention, after the terminal that identifies the access network is the smart terminal, the mobility management network element may perform some optimization processing for the smart terminal, such as any one or more of the following:

(1) When congestion occurs on the network side, for the PDP context activation request initiated by the smart terminal, the fake access point is notified that the currently requested PDP context of the terminal has been successfully activated; (2) resetting the smart The time when the terminal air interface connection is released.

Of course, in the embodiment of the present invention, there may be multiple optimization processes that can be performed by the network side for the smart terminal, and the detailed description is continued below.

As shown in FIG. 5, it is another flowchart of the network optimization method based on the smart terminal in the embodiment of the present invention, which includes the following steps:

Step 501: The network element to be optimized receives the first indication information sent by the mobility management network element. Step 502: The network element to be optimized determines, according to the first indication information, that the terminal that accesses the network is an intelligent terminal, and performs the Optimized processing of the terminal.

In the embodiment of the present invention, the method further includes the following steps: The network element to be optimized receives the second indication information sent by the mobility management network element;

The gateway network element keeps the PDP context in an active state, and does not actively initiate a PDP context local deactivation process;

The access network element, when detecting no data transmission, forcibly switches the state of the intelligent terminal to a cell paging channel state or a UTRAN registration domain paging channel state;

The contracting database inserts a set of security authentication vectors into the mobility management network element when performing security authentication on the smart terminal; when congestion occurs on the network side, the mobility management network element is not attached when the smart terminal is attached Insert user subscription data, and insert user subscription data when doing business.

It can be seen that, in the method of the embodiment of the present invention, the network side accurately identifies the smart terminal according to the behavior characteristics unique to the smart terminal, and performs optimization processing for the smart terminal. For the operator, the signaling interaction between the intelligent terminal and the network can be reduced, the signaling load on the network side can be optimized, and the network congestion risk can be reduced. In the case of network congestion, the access of the intelligent terminal is effectively rejected, and the network is guaranteed to operate normally and reliably. For users, users can quickly access the mobile Internet at any time to enhance the business experience of intelligent terminal users.

It should be noted that the smart terminal described in the embodiment of the present invention is not a smart terminal that is strictly defined, but refers to a terminal that satisfies certain characteristics and has certain behavior.
