Problems solved by technology

After obtaining the ANDSF policy, the UE directly performs the subsequent network selection and data flow switching process, which lacks traditional network side control.
The problem with this method is that because the access network (RAN) side (including 3GPP and non-3GPP access network sides) does not control the process, the service quality may not be guaranteed during the handover process
[0036] However, the current ANDSF-based strategy does not take into account the load information of the RAN, and LTE network elements cannot obtain the load of the WLAN

Embodiment 1

[0139] The eNB configures the AP to measure the WLAN channel utilization:

[0140] If the eNB configures the AP to configure the channel utilization of the WLAN, after the AP receives the message, the AP will measure the channel utilization of the WLAN and report the measurement result to the eNB. The eNB will know the load status of the WLAN based on the measurement result;

[0141] You can also define the following events to trigger measurement reporting based on the measurement, for example:

[0142] D1. The channel utilization rate is higher than a certain threshold (D1 is the event name, and the event name in the embodiment of the present invention can be replaced by other names):

[0143] like Figure 9b As shown in , the AP is configured to measure the channel utilization rate, the measurement flag is 1, and the reporting configuration is D1 event. That is, if the channel utilization rate is higher than a certain threshold, the AP will report the measurement result. ...

Embodiment 2

[0149] Configure the AP to measure the set noise power:

[0150] Taking the non-IEEE802.11 noise power as an example, the AP will measure the non-IEEE802.11 noise power and report the measurement result to the eNB. The eNB can perform load balancing reference or interference coordination reference based on the measurement results;

[0151]It is also possible to trigger a measurement reporting event based on the measurement definition as follows, for example:

[0152] D3, non-IEEE802.11 noise power is higher than a certain threshold:

[0153] If the AP detects that the non-IEEE802.11 noise power is higher than the threshold, and the condition for triggering a measurement report is met, the AP organizes a measurement report message; the report message is triggered by the measurement event D3.

[0154] D4, non-IEEE802.11 noise power is lower than a certain threshold:

[0155] If the AP detects that the non-IEEE802.11 noise power is lower than the threshold and the condition fo...

Embodiment 3

[0157] Configure the AP to report the signal strength and communication quality map of the WLAN under it:

[0158] The AP can use the measurement of the STA under it to obtain a detailed map of the precise signal strength and communication quality within its coverage area, and return it to the eNB; the eNB can use the measurement result as a reference for load balancing or guide the UE based on the measurement result Perform network selection and switching.

Abstract

The invention discloses a WLAN load determination method, device and system, and relates to communication technology. The AP measures the relevant parameters of the WLAN load according to the pre-configuration, and then sends the obtained measurement results to the base station. In this way, the base station can obtain the WLAN load The related parameters determine the WLAN load.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, device and system for determining WLAN load. Background technique [0002] With the emergence of new wireless access technologies, the development trend of future networks is a heterogeneous network that integrates multiple wireless access technologies. Current typical access technologies include UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System), LTE (Long Term Evolution, Long Term Evolution), LTE-A ( Long Term Evolution-Advanced, long-term evolution enhancement) and typical technologies such as WIFI (Wireless Fidelity, Wireless Fidelity) not defined by 3GPP. [0003] In a typical network in the future, LTE will be integrated with WLAN (Wireless Local Area Network), such as figure 1 shown. LTE covers a wide range, usually as wide-area coverage, and can provide users with good mobility support. However, WLAN has a small c...
