Base station can determine the channel width (alternatively, communication pattern) communicated between UE and AP as a result,.

Situation B

Receive the first ability letter for being used to indicate the channel width that the user equipment can be supported of user equipment transmission Breath；

Receive the second ability information for being used to indicate the channel width that the WLAN AP can be supported of WLAN AP transmission；

According to the first ability information and the second ability information, determines and communicated between the user equipment and the WLAN AP Used channel width.

Specifically, for example, UE can send above-mentioned HT Capabilities (first to base station before UE access AP An example of ability information), also, AP can send above-mentioned HT Capabilities (an example of the second ability information) to base station To which the HT Capabilities that the HT Capabilities and AP that base station can be sent according to UE are sent determines UE and AP Between the channel width that communicates, for example, if UE and AP support to send and receive 40MHz PPDU, AP can determine UE and The channel width communicated between AP is 20MHz or more, such as 40MHz.For another example if AP support sends and receivees 40MHz PPDU, but UE does not support to send and receive 40MHz PPDU and only support to send and receive 20MHz PPDU, then and AP can be determined The channel width communicated between UE and AP is 20MHz or less.

It should be understood that the HT Capabilities listed above as the first ability information and the second ability information is only Exemplary illustration, the present invention is not limited to this, other can indicate that the information for the channel width that UE and AP can be supported is fallen Enter in protection scope of the present invention, for example, it is also possible to only choose the Supported Channel in HT Capabilities Width Set is as the first ability information and the second ability information.

In S120, base station can determine bypass flow.

Optionally, this is according to the channel width, via the GTP tunnel, carries out mesh by the WLAN AP and the user equipment Mark the transmission of data, comprising:

According to the channel width, determine down target data, wherein the target downlink data be whole in the carrying or Part downlink data；

Via the GTP tunnel, the down target data are sent to the WLAN AP, in order to which the WLAN AP is set to the user The standby forwarding down target data.

Specifically, base station can direct root in downlink (that is, base station obtains data from gateway and is handed down to UE) According to the channel width determined in S110, the bypass flow (that is, down target data) of downlink is determined.For example, base station can be pre- The mapping relations between each bypass flow and each channel width (alternatively, communication pattern) are first determined, if UE and AP can work Under the communication pattern (that is, high-throughput communication mode) of 20/40MHz, base station can search high-throughput in the mapping relations Bypass flow corresponding to the communication pattern of communication pattern.Certainly, divide corresponding to the communication pattern of high-throughput communication mode Flowing flow can be much larger than bypass flow corresponding to non-high-throughput communication pattern.

Optionally, the transmission of target data, packet should be carried out by the WLAN AP and the user equipment via the GTP tunnel It includes:

Second channel bandwidth, which is sent, to the user equipment indicates that information, second channel bandwidth instruction information are used to indicate this Channel width used in being communicated between user equipment and the WLAN AP, in order to which the user equipment is according to the second channel band Width instruction information, determines uplink target data, wherein the target upstream data is line number in all or part in the carrying According to；

Via the GTP tunnel, the uplink target data of WLAN AP transmission is received, which is the use Family equipment is sent to the WLAN AP's.

Specifically, for example, in above situation B, since UE not yet accesses AP, UE and AP both sides do not determine The channel width communicated each other, in this case, the channel width determined in S110 can be handed down to UE by base station, thus UE can determine the bypass flow (uplink of uplink (UE sends data to gateway via base station) according to the channel width Target data).For example, UE can make bypass flow larger if the channel width of base station instruction is 40MHz.For another example such as The channel width of fruit base station instruction is 20MHz, then UE can make bypass flow smaller.Certainly, point when channel width is 40MHz Flow bypass flow when flow can be 20MHz much larger than channel width.

In addition, being occupied there are auxiliary channel by other AP etc. in the communication process of UE and AP and leading to not continue in height The case where being communicated under throughput communication mode, alternatively, there are the auxiliary channels (not occupied by other AP etc.) that AP discovery is able to use And the case where being communicated under allowing hand over to high-throughput communication mode, in this case, after UE can receive the change that AP is sent HT Operation determines that channel width changes, and it is possible to the channel width after variation is notified into base station, thus, base Bypass flow can be redefined according to the channel width after variation by standing.

Optionally, this method further include:

The channel switching information that the user equipment or the WLAN AP are sent is received, which is used to indicate this Channel used in communicating between user equipment and the WLAN AP switches and completes the time of the switching；And

This is according to the channel width, via the GTP tunnel, carries out target data by the WLAN AP and the user equipment Transmission, comprising:

Pass through the WLAN AP and the use via the GTP tunnel according to the channel width and the channel indication message The transmission of family equipment progress target data.

Specifically, for example, there are AP when AP detects that currently used auxiliary channel is Chong Die with the main channel of other AP Need the case where current auxiliary channel is switched into a new channel of operation.In this case, AP can be for example, beacon frame (Beacon), it visits and detects response (Probe Response), channel-switch-announcement (Channel Switch Announcement) etc. Channel Switch Announcement is carried in message, to notify UE switching channel.The Channel Switch Announcement may include following cell:

Channel mode (Channel Switch Mode), is used to indicate whether UE can resume in channel switching relaying Transmission of data；

New channel number (New Channel Number), is used to indicate the channel number that will be switched to；

Channel-switch count (Channel Switch Count), the time being used to indicate before being switched to new channel success.

To which, UE or AP can be by, for example, RRC specific messages by channel Channel Switch Announcement The relevant parameter (an example of channel indication message) of the inside is sent to base station, thus, base station can be according to Channel Switch Conut assesses the time that UE and AP complete channel switching, thus, base station with do not pass through when channel switches AP into Row shunts, and after the completion of switching, re-executes branching process.

It should be noted that when causing the channel width of switching front and back difference occur because carrying out above-mentioned channel switching, Base station can reacquire the channel width after switching, and redefine bypass flow, the process in the process and above-mentioned S110 Similar, here, in order to avoid repeating, the description thereof will be omitted.

In addition, the communication capacity (channel width that can be supported) of UE and AP listed above can be the absolute of UE and AP Communication capacity is also possible to the relative communication ability of UE and AP within a certain period of time, for example, for AP, if currently without The auxiliary channel (all channels are occupied by other AP) that can be used, then the communication bandwidth that cannot support 40MHz of current AP, together Reason, if currently having the auxiliary channel (channel is not Chong Die with the main channel of other AP) that can be used, current AP's can be propped up Hold the communication bandwidth of 40MHz.

More than, list application of the method for transmission data of the invention in 802.11n version, but the present invention and unlimited Due to this, for example, introducing higher throughput (VHT, Very High Throughput) mode energy in 802.11ac version The bandwidth of highest 160MHz is supported to state its branch by VHT Capabilities cell similarly for the UE with VHT ability The VHT characteristic held, such as, if support the channel width of 80MHz+80MHz or 160MHz (by Supported Channel Width Set instruction), also, the channel width that AP can be supported is four kinds, that is, 20MHz, 40MHz, 80MHz and 160MHz Or 80MHz+80MHz.In this case, for example, can be replaced using in above-mentioned S110 and S120 by VHT Capabilities HT Capabilities, in addition to finally determining channel width is there may be other than difference, other the step of and method with In 802.11n version using similar, here, in order to avoid repeating, the description thereof will be omitted.

In addition, for example, there may be no matter any time AP is equal if being provided only with (or a small amount of) AP in system Main channel can be provided to UE and the case where auxiliary channel, at this point, version that UE and AP can negotiate to communicate each other (for example, Any version in 802.11a/b/g, 802.11n or 802.11ac), and it is reported to base station, thus, base station can be according to current The version of communication, determines bypass flow, for example, if communications version is 802.11a/b/g, base station can determine UE and AP it Between the channel width that communicates be 20MHz, if communications version is 802.11n, base station can determine to be communicated between UE and AP Channel width is 40MHz, if communications version is 802.11ac, base station can determine the channel width communicated between UE and AP For 80MHz or higher.Alternatively, UE and AP can also report respectively its support version, thus base station can according in the two compared with Low version determines the channel width communicated between UE and AP, for example, if UE only supports 802.11a/b/g, and base station is supported The whole of 802.11a/b/g, 802.11n and 802.11ac, the then version supported using UE can determine between UE and AP as foundation The channel width of communication is 20MHz.
