Description
Technical field
The present invention relates to mobile communications network, particularly relate to the control method of a kind of terminal access target frequency bands, device and mobile network.
Background technology
Terminal knows the AP(Access Point in region by scanning process, access point) coverage information.According to IEEE802.11 agreement regulation, terminal obtains periphery wlan network coverage condition can based on following active scan, drive sweep two schemes:
1) active scan: as shown in Figure 1, end of scan sends " probe request " explore frame, the target BS SID(target AP in the middle of management frames) extend this as complete 1 broadcast BSSID.The AP receiving probe request frame will reply probe response, and terminal knows that periphery covers AP thus.
2) drive sweep: as shown in Figure 2, end of scan does not send " probe request ", but monitors the beacon(broadcast frame that sends of AP), know the covering AP of periphery.
At present, wlan device carries out commercialization according to the agreement regulation of IEEE802.11, and existing network WLANAP works in mixed mode: not only respond probe request but also broadcast beacon.
Generally terminal is according to the relation that is associated after setting themselves rule selected target AP.Based on general technical scheme, after terminal gets periphery AP coverage information, the target AP associated is carried out in meeting according to setting themselves rules selection.This " setting rule " includes but not limited to the AP selecting signal to noise ratio the highest, or the AP that field intensity is the highest.Specify according to IEEE802.11 agreement, terminal select target AP(target BS SID) signaling process is as Fig. 3 afterwards, through verification process (State1 is mutual to the Authentication of State2), association process (State2 is to the Association of State3), terminal is associated with AP relation, and selected AP is by the data retransmission of responsible terminal.
There is following shortcoming in above prior art: because terminal has right to choose to the target AP that self associates, to network side, the uncontrollable terminal of network side wishes that the BSSID that it associates associates, cause terminal skewness weighing apparatus between each BSSID, terminal skewness weighing apparatus between the BSSID particularly occurring 2.4GHz, 5GHz, covered the scheme works promoting network capacity had a greatly reduced quality by many AP, multiband overlap, terminal perception speed is low.
(1) generally WLAN needs many AP overlap to cover overall network capacity in lifting region.
According to IEEE agreement and the basic general knowledge of radio communication, single AP can the terminal quantity with carrying be limited, and along with unit/terminal rate requirement increase, single AP can need corresponding reduction by the terminal quantity with carrying.When the terminal band in a fixed area carry quantity exceed the ability of single AP time, the method that network side generally will be covered by many AP overlap in same region improve overall network capacity, and the overlapping AP covered generally needs to be configured to different frequencies.
(2) WLAN5GHz frequency range is the Main Means of hoist capacity.
According to IEEE protocol definition, WLAN generally operable frequency comprises 2.4GHz frequency range, 5GHz frequency range.2.4GHz the available non-overlapped frequency of frequency range only has 3, and be easy to be subject to the interference of the equipment such as bluetooth and reduce network capabilities, corresponding 5GHz frequency range can non-overlapped frequency quantity reach 5 (Chinese Industrial Standards (CIS)s), and interference source is far below 2.4GHz frequency range.Consider this factor, method i.e. overlapping covering, the more 5GHz of the use frequency overlap of the most reliable hoist capacity of network side cover.AP equipment conventional in existing network is generally all configured with two cover radio frequency transceivers, provides the covering of 2.4GHz, 5GHz respectively, is convenient in engineering, provide multifrequency point, multiband overlap to cover and promotes network capacity.
(3) because terminal selects the target AP of association voluntarily, easily there is terminal skewness weighing apparatus between frequency range, cause terminal perception speed low.
With reference to the open file " based on the research of the AP handover mechanism of throughput in WLAN " of " science and technology and engineering ", be trigger according to the size of wireless terminal (MH) snr of received signal (SNR) switch and select AP in prior art, the AP being namely terminal selection access according to received signal to noise ratio is the customary means of this area.And according to electromagnetic wave propagation, attenuation characteristic, when 2.4GHz frequency, 5GHz frequency co-located, same to power (being generally EIRP100 milliwatt), the 2.4GHz frequency power that terminal monitoring arrives will higher than 5GHz frequency, cause terminal to be preferentially associated with on the AP of 2.4GHz frequency, what network side was wished is difficult to reach by the target of 5GHz frequency overlap covering hoist capacity.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 4, the control method of terminal access target frequency bands provided by the invention, comprises step:
S401, the present invention prestores the support situation of terminal to double frequency (as an embodiment on AP, realize by information bank STA list), AP is after receiving the probe request message (S402) of terminal, according to the support situation of pre-recorded described terminal to double frequency, send the probe response information (S403) of the frequency range supported to described terminal.
As an embodiment, the access priority of each frequency range set can also be prestored, send the probe response information of the frequency range supported according to the priority of each frequency range preset to described terminal.
Whether the support situation of described pre-recorded described terminal to double frequency comprises supports the first frequency range, whether supports the information such as the second frequency range.
As a preferred embodiment, the described first frequency range probe request message amount that the support situation of described pre-recorded described terminal to double frequency also comprises timer, receives; The effect of these two information is proberequest message amount that a certain terminal that in record certain hour interval, AP receives sends in the first frequency range, when described probe request message amount reaches predetermined threshold, then described terminal sends the probe response information of described first frequency range.
Present invention also offers end message maintenance scheme, the distribution of the STAlist in a group between AP can be realized and share, the operational effect of this control algolithm can be promoted further.
Scheme one: described AP periodically broadcasts the described terminal of the record of self to the support situation of double frequency with multicast protocol, and carries out merging treatment to the support situation of described terminal to double frequency that other AP received record.
Scheme two: the support situation of the described terminal of self record to double frequency is periodically sent to AC by described AP, the described terminal of the self record that the AP in a group reports by AC is incorporated into the support situation of described terminal to double frequency of self record to all in group AP, AP to regularly mass-sending after the support situation integration of double frequency.
In order to technical scheme of the present invention can be understood more clearly, below with the first frequency range for 2.4GHZ, the second frequency range is 5GHZ is example, sets forth an application example of the present invention.
This application example is the end message storehouse (STA list) that AP verifies the machine after receiving the probe request message of terminal, if terminal supports double frequency, reply probe response with 5GHz frequency range, realize the guiding to terminal priority access 5GHz, control.
For reaching such scheme, AP needs maintenance STA list, and list for major key, comprises the 2.4GHz proberequest message amount whether supported 2.4GHz, whether support 5GHz, timer1 timer, receive with STA MAC.The probe request message amount that a certain terminal that AP in certain hour interval receives sends in 2.4GHz frequency range is recorded in the effect of " timer1 timer " and " the 2.4GHz probe request message amount received " two information.
Detailed AP handling process is as Fig. 5, and after the probe request message receiving terminal transmission, first AP retrieves STA list, if terminal supports WLAN two-band (2.4GHz, 5GHz), then preferential with 5GHz frequency range reply probe response message.If AP is the accumulative proberequest message receiving the 2.4GHz frequency range of more than this terminal 5 times (can according to the different threshold value of different requirements set) within the timer1 time interval, then AP replys probe response with 2.4GHz network interface card, avoids dual band terminal setpoint frequency to cause associate unsuccessfully or to associate duration long and affect perception.
In prior art, the target AP of terminal access is selected voluntarily by terminal, network side does not possess control ability, there is the problems such as load between double frequency is unbalanced in existing network, this application example improves the control ability of network side, has preferably effect to lifting network performance and terminal perception.Contrast gsm protocol and WLAN agreement is visible, and the control ability of network side is too low is the key point of WLAN atypical characteristics, and this application example is a key point of lifting wlan network control ability, is the key point that lifting WLAN develops to Working level network system.
Generally AP safeguards that STA list can ensure that such scheme normally performs voluntarily.As the further improvement of this application example, based on following end message maintenance scheme, the distribution of the STA list in a group between AP can be realized and share, the operational effect of this control algolithm can be promoted further.
Scheme 1: multicast scheme.To other AP received, AP periodically with the STA list of multicast protocol broadcast self, and informs that list carries out merging treatment.
Scheme 2:AC(Access Controller, access controller) Managed Solution.The STA list of self is periodically sent to AC by AP, after the STA list that AP in a group (as a vlan, a NASID or a group according to the artificial setting of other rules) reports integrates by AC, regularly mass-sending is incorporated into self STA list to all in group AP, AP.
