Access control method and related wireless communication system

An access control method for a wireless key distributor in a wireless communication system, the access control method comprising:

• activating an application unit of the wireless key distributor;
• sending a distinguish signal to a wireless client via a near field communication (NFC) communications when the wireless client approaches the wireless key distributor, wherein the distinguish signal is associated with the application unit and the distinguish signal matches to a content of an Intent filter registered by an application unit of the wireless client;
• receiving an access information request from the wireless client via a near field communication (NFC) communications;
• querying access information from a data storage of the wireless key distributor;
• and
• sending the access information comprising a service set identifier and a pre-shard key to the wireless client with an access authority comprising at least one of a QoS level and an access time limitation.

A wireless client device comprising:

• an application unit for configuring the Wi-Fi settings comprising a service set identifier and a pre-shard key, the application unit being software stored in a non-transitory storage medium to be executed by a processor;
• a near field communication (NFC) circuit for receiving a distinguish signal from a wireless key distributor when the wireless client device approaches the wireless key distributor;
• and
• a processing module coupled to the NFC circuit for activating the application unit of the wireless client device upon reception of the distinguish signal, wherein the distinguish signal is associated with the application unit and the distinguish signal matches to a content of an Intent filter registered by the application unit, the processing module being software stored in the non-transitory storage medium to be executed by the processor;
• wherein the wireless client device has an access authority comprising at least one of a QoS level and an access time limitation, and
• wherein the application unit further sends an access information request to the wireless key distributor and receives access information comprising the service set identifier and the pre-shard key from the wireless key distributor via a near field communication (NFC) communications.

A wireless key distributor device comprising:

• an application unit for distributing access information comprising a service set identifier and a pre-shard key, the application unit being software stored in a non-transitory storage medium to be executed by a processor, wherein the application unit further receives an access information request from the wireless client and sends access information to the wireless client via a NFC communications;
• a processing module coupled to the application unit for executing the application unit, the processing module being software stored in the non-transitory storage medium to be executed by the processor;
• and
• a near field communication (NFC) circuit for sending a distinguish signal to a wireless client when the wireless client approaches the wireless key distributor device, wherein the distinguish signal is associated with the application unit and the distinguish signal matches to a content of an Intent filter registered by an application unit of the wireless client, and the wireless client has an access authority comprising at least one of a QoS level and an access time limitation.

A wireless communication system comprising:

• at least one wireless client comprising:
• a first application unit for executing access control, the first application unit being software stored in a non-transitory storage medium to be executed by a processor;
• a first near field communication (NFC) circuit for receiving a distinguish signal;
• and
• a first processing module coupled to the first NFC circuit for activating the first application unit upon reception of the distinguish signal, the first processing module being software stored in the non-transitory storage medium to be executed by the processor;
• at least one wireless key distributor comprising:
• a second application unit for executing access control, the second application unit being software stored in a non-transitory storage medium to be executed by a processor;
• a second processing module coupled to the second application unit for activating the second application unit, the second processing module being software stored in the non-transitory storage medium to be executed by the processor;
• and
• a second NFC circuit for sending the distinguish signal to the first NFC circuit when the wireless client approaches the wireless key distributor;
• a wireless access point (AP) coupled to the first wireless distributor for providing the at least one wireless client connection services;
• and
• a wireless local area network (WLAN) controller coupled to the at least one wireless key distributor for providing access authority to the wireless client according to the at least one wireless key distributor and storing the access authority, wherein the access authority corresponds to the access information and comprises at least one of a QoS level and an access time limitation;
• wherein, the distinguish signal is associated with the first application unit and the second application unit and the distinguish signal matches to a content of an Intent filter registered by the first application unit;
• wherein the first application unit further sends an access information request to the second application unit and receives access information comprising a service set identifier and a pre-shard key from the second application unit via a near field communication (NFC) communications.
