The technical problems, technical solutions, and advantages of the embodiments of the present invention will become more apparent from the following detailed description.

The network access control method of the embodiment of the present invention is used by the first network side device, and the method includes: Step 11: Receive a first message that carries the terminal capability information reported by the terminal;

Step 12: Determine, according to the terminal capability information, whether the terminal supports the Wif i optimization function, and obtain a determination result;

Step 13: When the determining result indicates that the terminal supports the Wifi optimization function, when the terminal enters the WLAN coverage, the WLAN measurement configuration message is sent to the terminal, so that the terminal can be configured according to the WLAN. The measurement configuration carried in the message is measured to obtain a measurement result for access control processing.

The method first receives the first message of the terminal capability information reported by the terminal, and determines whether the terminal supports the Wifi optimization function according to the terminal capability information. When the terminal supports the Wifi optimization function and the terminal enters the WLAN coverage, the terminal is sent to the terminal. The WLAN measurement configuration information is sent, and the terminal may perform further measurement according to the measurement configuration in the received measurement configuration information, and finally obtain the measurement result of the access control process.

When performing terminal capability reporting (UE capability information), the terminal needs to carry the capability of supporting Wifi offloading or whether the terminal has the information of the Wifi module. When the terminal enters the area with WLAN coverage, the terminal allows the network to configure the Wifi offloading optimization for the terminal. Program.

For LTE systems, lbit can be used to increase the corresponding IE UE-EUTRA-Capability. Capability indication, when the terminal performs attach or performs TAU (tracking area updating), the capability information is reported;

For the UTRAN system, the existing capability of the existing IE UE radio access capability or the UE radio access capability compressed or the UE radio access capability comp 2 or the UE radio access capability extension may be used to perform the attach or the RAU in the terminal. ( routing area updating ), the j3⁄4i capability information is only available.

Through the above method, the network side device only performs related measurement configuration on the terminal with the Wifi module and the Wifi offloading function, thereby avoiding unnecessary signaling overhead and affecting the user experience.

There are two ways to perform access control processing based on the measurement results of the terminal:

<Mode 1> The first network side device receives the measurement result reported by the terminal for access control processing;

<Mode 2> The terminal directly performs access control processing according to the measurement result.

As for how the network side device or the terminal performs the access control process according to the measurement result, it is not the focus of the embodiment of the present invention, and may be based on any existing access policy (such as accessing a network with a lower load and accessing a signal). The access control process is performed on a network with good quality, etc., and will not be described in further detail here.

In a specific embodiment of the present invention, when the access control process is performed by the first network side device, the network access control method further includes:

Step 14. Receive the measurement result reported by the terminal for access control processing.

At the same time, it is considered that after switching from one network side device to another network side device, the network side device here may be specifically a base station, and needs to re-report whether it supports the Wifi offloading function and the obtained nearby WLAN information, which not only increases The air interface signaling overhead may also cause other control signaling overheads due to the unsatisfactory reporting, and affect the effect of the Wifi offloading. Therefore, the network access control method provided by the embodiment of the present invention preferably further includes:

Step 15: When the terminal switches from the first network side device to the second network side device, forward the first message and the measurement result to the second network side device, so that the second network side device The device can determine whether the terminal supports the Wifi optimization function according to the terminal capability information, and can utilize At least part of the measurement results are subjected to access control processing.

When the terminal switches from the first network side device to the second network side device, if the terminal reports to the first network side device that it supports Wif i off loading capability or has a Wif i module, the obtained WLAN network information (such as an AP) The traffic, the number of accesses, the average access time, the delay of the data packet, and the packet loss rate, the first network side device needs to forward the information to the second network side device.

Specifically, in the LTE system, the information may be transmitted through the X2 interface. If there is no X2 interface between the eNBs, the first eNB may notify 匪 E through the S1 interface, and then notify the second eNB through the S1 interface.

In the UTRAN system, if the source of the handover and the destination NB are under the same RNC, this information can be transmitted through the Iub interface (the interface between the NB and the RNC); if the source of the handover and the destination NB are under different RNCs , this information can be passed between the NB through the Iub interface and the Iur interface (the interface between the RNCs).

The signaling carrying the message may be an RRC signaling HandoverPre- s or s (in the LTE system), or a Radio l ink setup reques t message (in the UTRAN system), or may be sent from the source base station to the target base station. Other RRC signaling.

The first network side device forwards the first message and the measurement result to the second network side device, and the second network side device can determine, according to the first message, whether the terminal supports the Wif i optimization function. And when the terminal is switched from the first network side device to the second network side device, some information in the measurement result of the first network side device may be directly utilized for access control processing, for example, Network information of the WLAN that is not affected by the terminal mobile, etc., but some cannot be directly utilized, such as the signal quality of the AP affected by the terminal mobile, etc., so the second network side device can utilize at least part of the measurement results. Access control processing.

The foregoing process can avoid the increase of the air interface signaling overhead and the overhead of other control signaling due to the unsatisfactory reporting, which further affects the effect of the Wif i offload.

When the network side determines that the terminal enters the area covered by the WLAN, and the terminal has the function of supporting Wi fi off loading optimization or the Wif i module, the eNB/NB will configure the relevant terminals by means of RRC signaling (such as RRCConnectionReconf igurat ion). The optimization solution, wherein the measurement configuration comprises: a measurement target and a measurement parameter.

The measurement target is specifically: an SSID of the WLAN, or a working channel, or a MAC address of the AP; The measurement parameters are: a signal quality parameter of the target AP or a congestion state parameter of the target WLAN, such as: an average delay of the data packet, a packet loss rate, and the like.

After the network side device configures the terminal with the measurement information of the potential target WLAN (such as SS ID, working channel, MAC address, etc.), the terminal scans, but because the scanned APs are in an overload state, the terminal may not be able to establish them. connection. It is very likely that the terminal will not be able to establish a connection with the WLAN for a long time, and the cellular network will always wait for the scan result, which will ultimately affect the user experience.

In order to avoid the above situation, in the embodiment of the present invention, a trigger condition is set on a measurement message, and when the condition is met, the terminal reports the measurement result, that is, the measurement result in the foregoing method is reported by the terminal when the trigger condition of the measurement message reporting is satisfied. result.

The measurement message reporting triggering condition in the embodiment of the present invention may be:

The signal quality parameter of the access point conforms to the preset signal quality judgment condition: the absolute value of the signal quality parameter of the access point is higher than the first threshold; or

However, it should be understood that the above-mentioned measurement message reporting triggering condition is merely an exemplary description, and the embodiment of the present invention can also adopt other measurement message reporting triggering conditions, which is not described here.

The measurement message reporting triggering condition may be a message that is pre-configured and stored in the terminal, but may also be a message delivered to the terminal by using the WLAN measurement configuration message.

Several specific examples of reporting the triggering conditions of the above measurement messages are as follows:

a. The absolute value of the RSRP or RSRQ received by an AP is higher than a certain threshold, or

b. The RSRP or RSRQ value relative to the cellular network serving cell is higher than a certain threshold, or c. A latest reporting time timer t imer is set, that is, after the t imer expires, the terminal must report the obtained information to the network side. To prevent the measured data from always meeting the reporting event of the measurement report after the terminal enters the busy area of the WLAN, or

d. The reported period arrives.

The embodiment of the present invention defines a trigger condition, such as a signal, by reporting, by the terminal, the measured WLAN information. The quality of the situation is higher than a certain threshold, the reported period, the latest reporting time point, etc., to avoid the situation that the cellular network has been waiting for the measurement.
