Description
Technical field
The present invention relates to network field, particularly relate to a kind of method, the Apparatus and system that promote control point discovering device in wireless network.
Background technology
Because the quality of network transmission signal is easily subject to environmental impact, quality as wireless network transmissions signal is easily subject to the impact of the equipment such as bluetooth earphone or microwave oven in work, when the quality of network transmission signal is deteriorated because of influenced, the message that equipment is sent out mutually by network is usually easily lost or occurs mistake.Because equipment room is by sending and receiving message and realize the mutual discovery of equipment room, if message dropping or occur mistake, then equipment may by Network finding each other.
Summary of the invention
The embodiment of the present invention provides a kind of method, the Apparatus and system that promote control point discovering device.
First aspect, embodiments provides a kind of method promoting control point discovering device in wireless network, comprising:
Test packet is sent to router;
Receive test back message, described test back message is sent by described router, for responding described test packet;
According to described test back message, judge that the quality of the first signal path transmitting described test packet and described test back message is whether in quality preset range;
If described quality is in described quality preset range, then in Preset Time to described router transmitting apparatus message N time; And
If described quality outside described quality preset range, then sends described equipment message M time to described router in described Preset Time;
Wherein, described equipment message sends with the forms of broadcasting via described router, the equipment that described control point finds to send described equipment message is beneficial to for being received by described control point, described control point controls described equipment after finding described equipment, M>N>0, and M and N is integer.
Advantageously, the present embodiment judges the quality of the first signal path according to test back message, thus learns the quality of secondary signal path.Time quality compared to secondary signal path better (being also that the quality of the first signal path is in preset range), the present embodiment is when second-rate (also namely the quality of the first signal path is outer in preset range) of secondary signal path, increase the number of times of transmitting apparatus message to increase the possibility that control point 108 receives equipment message, thus promote control point 108 discovering device 102.
In the first possible implementation of first aspect, described method is periodically performed with the first predetermined period.Periodically detect the first signal path quality and in time the number of times of adjustment transmitting apparatus message can promote control point 108 discovering device 102 in time.
In conjunction with first aspect, or the first possible implementation of first aspect, in the implementation that the second is possible, described quality preset range comprises message number preset range and time delay preset range;
Described according to described test back message, judge whether the quality of the first signal path of described test packet and described test back message comprises in quality preset range:
Judge that the message number of described test back message is whether in described message number preset range, and judge from the time interval between the moment to the moment receiving described test back message sending described test packet whether in described time delay preset range;
If described message number is in described message number preset range, and the described time interval is in described time delay preset range, then determine that described quality is in described quality preset range; And
If described message number is outside described message number preset range, or the described time interval is outside described time delay preset range, then determine that described quality is outside described quality preset range.
Owing to having considered pre-and time delay two factors of message number when the quality of judgement first signal path, relative to the deterministic process only considering a factor, the judged result accuracy of the present embodiment is higher.
In conjunction with first aspect, or any one possible implementation of first aspect the first to the second, in the implementation that the third is possible, described to router send test packet comprise: periodically send described test packet to router with the second predetermined period.Periodically send test packet and periodically can detect the quality of the first signal path thus the information of timely acquisition the first signal path quality, and adjust the number of times of transmitting apparatus message thus promote control point 108 discovering device 102.
In conjunction with first aspect, or first aspect first is to the third any one possible implementation, in the 4th kind of possible implementation, after completing and sending described equipment message, also comprises:
Receive the file request signal that control point sends, described file request request signal obtains the capabilities description file of described equipment, and described capabilities description file describes the function that described equipment has;
