Problems solved by technology

[0003] The WLAN network relieves the pressure on 3GPP network services in dense areas, but it also has its own disadvantages - the coverage of hotspots is small, and a large number of hotspots need to be laid
Moreover, the service flow of the network is closely related to the scope and time of user activities, and has certain spatiotemporal inhomogeneity.
As a result, a large number of APs are still in the normal working state even in idle time, resulting in considerable energy consumption and virtually increasing the operator's operating and maintenance costs
The currently established WLAN network is independent of the 3GPP network, and user services often exist in a single network, which does not allow network interruption or shutdown

Embodiment 1

[0116] This embodiment provides a method for a network management system to control an AP to implement energy-saving control. The network monitoring module in the network management system monitors the status of the WLAN and 3GPP network, and when the AP meets the energy-saving control conditions, the network monitoring module triggers the energy-saving control of the AP. The network manager first migrates the network services of the active users under the current AP, and after the processing is successful, sends an energy-saving control message to the AP to control the AP to enter a sleep state or reduce the transmission power. When the dormant AP satisfies the conditions for releasing the energy-saving control, the monitoring module in the network management sends a message of releasing the energy-saving control to the AP, and the AP returns to the normal working state.

Embodiment 2

[0149] Figure 7Shown is a flow chart of obtaining the SSID issued by the gateway PGW when the UE initially accesses the 3GPP network in the embodiment of the present application. When the UE accesses the 3GPP network, it obtains the SSID priority list when accessing the WLAN (the current congestion status will be obtained from the network management system before the 3GPP network sends the SSID priority list). When entering an area covered by a WLAN signal, Comprehensively utilize the issued SSID list, the locally stored SSID list, and the found SSID available around, and select the most suitable SSID access according to a certain strategy. Such as Figure 7 As shown, it specifically includes the following steps:

[0150] Step 701: After the UE is turned on, it finds that there is a 3GPP signal around, and initiates an attach request to the SGSN through the base station.

[0151] Step 702: SGSN / MME obtains user subscription information from the user subscription data serve...

[0164] Figure 8 Shown is a flow chart of the terminal UE accessing from the WLAN network after the 3GPP accesses the network in the embodiment of the present application. The terminal UE will select an appropriate SSID to access the WLAN network according to the SSID obtained during 3GPP access and other methods, and update the routing policy for uplink and downlink data services. Such as Figure 8 As shown, the specific steps are as follows:

[0165] Step 801: After accessing through 3GPP, the terminal UE has acquired the subscribed SSID priority list, and after finding that there is an available WLAN signal, the terminal UE initiates WLAN access to the AP.

[0166] Step 802: If the UE finds that the AP allows it to access, it will initiate the EAP authentication process for accessing the WLAN, using the (U)SIM card as a credential, and adopt the EAP-SIM / AKA authentication method.

[0167] Step 803a: After the EAP authentication is completed (at the end of the security au...

Abstract

The invention discloses a method, system and terminal for network monitoring and energy-saving control and a packet access gateway. The terminal selects a WLAN network to have access to the WLAN network according to an SSID priority list of WLAN networks issued by PGW having access to the 3GPP network; after the terminal has access to the WLAN network, the position information of the WLAN network is reported to the PGW, wherein the position information of the WLAN network comprises SSID and AP information. By the adoption of the method, system and terminal for network monitoring and energy-saving control and the packet access gateway, flow monitoring of the WLAN network side and the 3GPP network side of the terminal can be achieved, and therefore energy-saving flow distribution between the WLAN network and the 3GPP network can be achieved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a network monitoring and energy saving control method and system, a terminal and a packet access gateway. Background technique [0002] With the promotion of smart phones and the explosive development of mobile Internet services, the sudden increase in data traffic of mobile users has brought a huge impact on 2 / 3G mobile networks. The WLAN network is favored by operators for its advantages of relatively high bandwidth, simple installation, and relatively low cost. Various operators have considered distributing 3GPP network data by deploying WLAN hotspots in data hotspots. [0003] The WLAN network alleviates the business pressure of the 3GPP network in dense areas, but it also has its own disadvantages—the coverage of hotspots is small, and a large number of hotspots need to be laid. Moreover, the service flow of the network is closely related to the scope ...
