Abstract
The present invention provides a method for selecting a network controller and a station device. Supported channel width sets of multiple station STA devices are acquired; a PCP factor of the each STA device is generated according to a supported channel width set and an acquired directional multi-gigabit DMG capability information element of the each STA device, where the PCP factor includes the supported channel width set; a STA device with a largest PCP factor is selected as a PCP. Using the method for selecting a PCP and the STA device provided in the present invention can improve reliability of a wireless local area network WLAN.
Claims16
A method for selecting a network controller, comprising:
- acquiring supported channel width sets of multiple station (STA) devices;
- generating a personal basic service set (PBSS) control point (PCP) factor of each STA device of the multiple STA devices according to a supported channel width set and an acquired directional multi-gigabit (DMG) capability information element of each STA device, wherein the PCP factor comprises the supported channel width set;
- and
- selecting an STA device with a largest PCP factor from the multiple STA devices as the network controller;
- wherein the acquiring the supported channel width sets of the multiple STA devices, comprises performing at least one of:
- acquiring DMG capability information elements of the multiple STA devices, wherein the DMG capability information elements comprise DMG STA capability information and DMG PCP or access point (PCP/AP) capability information, wherein the DMG STA capability information or the DMG PCP/AP capability information comprises the supported channel width sets;
- or
- acquiring country information elements or supported operating classes information elements of the multiple STA devices, and acquiring the supported channel width sets according to channel spacing fields and channel starting frequency fields in at least one of the country information elements or the supported operating classes information elements.
5 more elements
A station (STA) device, comprising:
- a receiver configured to acquire supported channel width sets and directional multi-gigabit DMG) capability information elements of multiple STA devices, wherein the receiver is further configured to perform at least one of:
- acquire the DMG capability information elements of the multiple STA devices, wherein the DMG capability information elements comprise DMG STA capability information and DMG PCP or access point (PCP/AP) capability information, wherein the DMG STA capability information or the DMG PCP/AP capability information comprises the supported channel width sets, or
- acquire country information elements or supported operating classes information elements of the multiple STA devices, and acquire the supported channel width sets according to channel spacing fields and channel starting frequency fields in at least one of the country information elements or the supported operating classes information elements;
- a processor;
- a non-transitory computer readable medium connected to the processor and having stored thereon instructions that, when executed by the processor, cause the processor to:
- generate a personal basic service set (PBSS) control point (PCP) factor of each STA device of the multiple STA devices according to a supported channel width set and an acquired DMG capability information element of the each STA device, wherein the PCP factor comprises the supported channel width set, and select a STA device with a largest PCP factor as a PCP;
- and
- a bus, configured to implement communication between the receiver and the processor.
5 more elements
A station (STA) device, comprising:
- a receiver, configured to acquire a supported channel width set and directional multi-gigabit DMG) capability information element of a first STA devices, wherein the receiver is further configured to perform at least one of:
- acquire the DMG capability information element of the first STA device, wherein the DMG capability information element comprise:
- DMG STA capability information and DMG PCP or access point (PCP/AP) capability information, wherein the DMG STA capability information or the DMG PCP/AP capability information comprises the supported channel width set;
- or,
- acquire a country information element of the first STA device or a supported operating classes information element of the first STA device, and acquire the supported channel width set according to at least one of a channel spacing field and a channel starting frequency field in the country information element or a channel spacing field and a channel starting frequency field in the supported operating classes information element;
- a processor;
- a non-transitory computer readable medium connected to the processor and having stored thereon instructions that, when executed by the processor, cause the processor to:
