Situation A

Alternatively, channel width used in being communicated between the determination user equipment and the WLAN AP, including：

Receive the first channel width configured information that the user equipment or the WLAN AP are sent, wherein, the first channel width configured information is used to indicate the used channel width that communicates between the user equipment and the WLAN AP, and the channel width is by the user equipment with being determined after WLAN AP negotiations；According to the first channel width configured information, the used channel width that communicated between the user equipment and the WLAN AP is determined.

In embodiments of the present invention, determined after being consulted due to channel width by targeted customer with AP, therefore, targeted customer can know the channel width with AP both sides, so that, the channel width can be notified to base station by either one in targeted customer and AP, the present invention is simultaneously not particularly limited, for the ease of understanding and describing, below, so that user equipment notifies the channel width to base station as an example, illustrate.

In addition, in embodiments of the present invention, the wireless LAN communication between UE and AP can use existing various versions to communicate, for example, 802.11a/b/g versions, 802.11 η versions or 802.11ac versions.

For example, in 802.1 In versions（One of wireless LAN communication）In, 20 megahertzs (MHz) and 40MHz channel width can be used, 40MHz channels are made up of two adjacent 20MHz channels, to reach higher transmitted data rates.Also, AP is before using 40MHz channels, it is thus necessary to determine that this two adjacent 20MHz channels are not by other communication equipments（For example, other AP or Bluetooth communication equipment etc.) use.

Three kinds of communication patterns defined in 802.11 η versions：

High-throughput（Η Τ, High Throughput) pattern：AP and UE can support that, using 802.11 η versions, high-throughput can be realized.

Non-high-throughput（Non-HT, Non-High Throughput) pattern：AP and UE do not support 802.11 η versions, and use such as 802.11a/b/g versions, it is impossible to support high-throughput.

Mix high-throughput（HT Mixed, High Throughput Mixed) pattern：AP and UE 802.11 η and such as 802.11a/b/g versions can be supported simultaneously.

With HT abilities（In other words, 802.11 η versions are supported）UE, its HT ability to AP can be stated by Η Τ abilities (Capabilities) cell, for example, if support 40MHz bandwidth operations, if 40MHz bandwidth, the modulation of support and coding strategy can be tolerated（MCS, Modulation and Coding Scheme) type, if multiple-input, multiple-output etc. are supported, AP can determine UE operator scheme etc. according to UE HT abilities.

Hereinafter, for the ease of understanding and illustrating, so that the communications version between UE and AP is 802.11 η as an example, illustrate.

In embodiments of the present invention, base station can be for example, by wireless heterogeneous networks（RRC, Radio Resource Control) dedicated signaling or system broadcasts signaling indicate UE and WLAN AP negotiation patterns.Consult between UE and AP and determine that the process of channel width can be carried out when UE accesses AP, in this case, for example, eNB can be by WLAN AP BSSID（BSSID, Basic Service Set Identifier) or service set（SSID, Service Set Identifier) UE is given, so that, UE can be determined according to the BSSID or SSID and be accessed the AP.

In embodiments of the present invention, for example, for the UE of drive sweep, probe request message (Probe Request) or association request message can be sent to AP（Association Request), also, following information can be carried in above-mentioned message：

Overlapping Basic Service Set scanning allows（Overlapping Basic Service Set Scanning

Exemption Grant), for indicating whether the UE allows Overlapping Basic Service Set to scan. It should be understood that, the cell that 20/40 BSS Coexistence listed above are included is merely illustrative, the present invention is not limited to this, the present invention 20/40 BSS Coexistence can be same with 20/40 BSS Coexistence in the prior art, comprising its various cell.

HT Capabilities can include following cell：

It should be understood that, the cell that HT Capabilities listed above are included is merely illustrative, the present invention is not limited to this, and HT Capabilities of the invention can be same with HT Capabilities in the prior art, comprising its various cell.

AP is received after Probe Request or the Association Request of UE transmissions, ^ is determined according to above-mentioned HT Capabilities and 20/40 BSS Coexistence and is issued the probe response message (Probe Response) or associated response (Association Response) message for the UE

For example, when following decision conditions are met, AP can determine that the communication between UE can use 20/40MHZ communication patterns：

A. AP and UE can support 20/40MHz communication patterns, in other words, Supported Channel Width Set in AP and UE HT Capabilities are designated as supporting to receive and sending 40MHz PPDU (for example, Supported Channel Width Set are set to non-zero value）；

B. there is effective secondary carrier in wireless communication system（For example, not taken by other AP）, in other words, the Secondary Channel Offset in HT Operation can indicate effective auxiliary load. It should be understood that decision condition listed above is merely illustrative, the present invention is not limited to this, and other can be used in determining that the method for the channel width communicated between AP and UE is each fallen within protection scope of the present invention. HT Capabilities;

HT operates (HT Operation);

20/40 BSS Coexistence;

Overlapping BSS Scan Parameters;

Extended Capabilities;

Wherein, above-mentioned HT Capabilities, 20/40 BSS Coexistence and Extended

Capabilities effect and the HT Capabilities in Probe Request or Association Request, 20/40 BSS Coexistence are similar with Extended Capabilities effect, here, in order to avoid repeating, the description thereof will be omitted.

Also, HT Operation include following cell：

The channel number of main channel（Primary Channel), for indicating the main channel that AP is determined；Auxiliary channels offset (Secondary Channel Offset), for indicating skew of the auxiliary channel relative to main channel；

Channel width（Channel Width) it is used to indicate that the channel width that UE can use is 20MHz bandwidth or 40MHz bandwidth, in other words, UE can only use main channel or main channel and auxiliary channel both sides.

So as to which, UE is by the HT Operation got (one of the first channel width configured information）Report base station.Base station can determine the used channel width that communicated between UE and AP according to the HT Operation (specifically, being Channel Width).

It should be understood that, the particular content of first channel width configured information listed above is merely illustrative, the present invention is not limited to this, for example, UE is according to the HT Operation parameter evaluation peak transfer rates got, such as, if the channel width that can be used that Channel Width are indicated is 40MHz, it is 40Mbps that peak transfer rate, which can then be determined, and it is possible to by the peak transfer rate（Another example of first channel width configured information) report base station.And, the peak transfer rate, it can be an absolute value, such as 40Mbps or relative value, for example, basic, normal, high three thresholdings can be set, also, if the maximum rate exceedes the rate value corresponding to " height " thresholding, then the rate value being somebody's turn to do corresponding to " height " thresholding is sent to base station. Thus, base station can determine the channel width communicated between UE and AP（Or, communication pattern）.Situation B

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

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

According to the first ability information and the second ability information, the used channel width that communicated between the user equipment and the WLAN AP is determined.

Specifically, for example, before UE accesses AP, UE can send above-mentioned HT Capabilities (one of the first ability information to base station）, also, AP can send above-mentioned HT Capabilities (one of the second ability information to base station）So as to, the HT Capabilities that the HT Capabilities and AP that base station can be sent according to UE are sent, determine the channel width communicated between UE and AP, for example, if UE and AP supports to receive and send 40MHz PPDU, then AP can determine that the channel width communicated between UE and AP is more than 20MHz, such as 40MHz.If for another example AP is supported to receive and sent 40MHz PPDU, but UE does not support to receive and send 40MHz PPDU and only support to receive and send 20MHz PPDU, then AP can determine that the channel width communicated between UE and AP is below 20MHz.

It should be understood that the HT listed above as the first ability information and the second ability information

Capabilities is merely illustrative; 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 each fallen within protection scope of the present invention; for example, it is also possible to which the Supported Channel Width Set only chosen in HT Capabilities are used as the first ability information and the second ability information.

Thus, base station can determine the channel width communicated between UE and AP（Or, communication pattern）.In S120, base station can determine bypass flow.

Alternatively, this is according to the channel width, via the GTP tunnel, and the transmission of target data is carried out by the WLAN AP and the user equipment, including：

According to the channel width, down target data are determined, wherein, the target downlink data are all or part of downlink datas in the carrying；

Via the GTP tunnels, the down target data are sent to the WLAN AP, in order to this WLAN AP forward the down target data to the user equipment.

Specifically, when descending（That is, base station obtains data from gateway device and is handed down to UE), base station can determine descending bypass flow directly according to the channel width determined in S110（That is, down target data）.For example, base station can predefine each bypass flow and each channel width（Or, communication pattern）Between mapping relations, if UE and AP can be operated in 20/40MHz communication pattern（That is, high-throughput communication pattern）Under, base station can search the bypass flow corresponding to the communication pattern of high-throughput communication pattern in the mapping relations.Certainly, the bypass flow corresponding to the communication pattern of high-throughput communication pattern can be much larger than the bypass flow corresponding to non-high-throughput communication pattern.

Alternatively, the transmission of target data should be carried out by the WLAN AP and the user equipment via the GTP tunnel, including：

Second channel bandwidth configured information is sent to the user equipment, the second channel bandwidth configured information is used to indicate the used channel width that communicates between the user equipment and the WLAN AP, in order to which the user equipment is according to the second channel bandwidth configured information, determine up target data, wherein, the target upstream data is all or part of upstream data in the carrying；

Via the GTP tunnel, the up target data of WLAN AP transmissions is received, the up target data is that the user equipment is sent to the WLAN AP.

Specifically, for example, in above-mentioned situation B, because UE not yet accesses AP, therefore, the channel width that UE and AP both sides communicate between not determining, in the case of this, the channel width determined in S110 can be handed down to UE by base station, so that UE can be determined up according to the channel width（UE sends data via base station to gateway device）Bypass flow（Up target data）.For example, if the channel width that base station is indicated is 40MHz, UE can make bypass flow larger.For another example if the channel width that base station is indicated is 20MHz, UE can make bypass flow smaller.Certainly, bypass flow when bypass flow when channel width is 40MHz can be 20MHz much larger than channel width.

In addition, in UE and AP communication process, there is a situation where that auxiliary channel is taken by other AP etc. and leads to not continue to communicate under high-throughput communication pattern, or, there is the auxiliary channel that AP has found to use（Do not taken by other AP etc.) and allow hand over situation about being communicated to high-throughput communication pattern, in the case of this, UE can receive the HT Operation after the change of AP transmissions, determine that channel width changes, and it is possible to the channel width after change is notified into base station, so that, base station can redefine bypass flow according to the channel width after change.

Alternatively, this method also includes：

Receive the channel switching information that the user equipment or the WLAN AP are sent, the channel switching information The time of the switching is switched and completed for channel used in indicating to communicate between the user equipment and the WLAN AP；And

This is according to the channel width, via the GTP tunnel, and the transmission of target data is carried out by the WLAN AP and the user equipment, including：

According to the channel width and the channel indication message, via the GTP tunnels, by this

WLAN AP carry out the transmission of target data with the user equipment.

Specifically, for example, when AP detect currently used auxiliary channel it is overlapping with other AP main channel when, there is a situation where AP need current auxiliary channel is switched into a new channel of operation.In this case, AP can be for example, beacon frame（Beacon), visit and detect response（Probe Response), Channel Switch Announcement are carried in the message such as channel-switch-announcement (Channel Switch Announcement), to notify UE to switch channel.The Channel Switch Aimoimcement can include following cell：

Channel mode（Channel Switch Mode), for indicating whether UE can resume transmission of data in channel switching relaying；

New channel number（New Channel Number), for the channel number for indicating to switch to；Channel-switch count（Channel Switch Count), for indicating to be switched to the time before new channel success.

So as to which, UE or AP can be by, for example, RRC specific messages by the relevant parameter inside channel Channel Switch Announcement（One of channel indication message）Base station is sent to, so that, base station can assess the time that UE and AP completes channel switching according to Channel Switch Conut, so as to, base station after the completion of switching, re-executes branching process not shunted when channel switches by AP.

It should be noted that, when there is difference in the channel width before and after causing switching because carrying out above-mentioned channel switching, base station can reacquire the channel width after switching, and redefine bypass flow, the process is similar with the process in above-mentioned S110, here, in order to avoid repeating, the description thereof will be omitted.

In addition, UE listed above and AP communication capacity（The channel width that can be supported）Can be the relative communication ability of UE and AP absolute communication capacity or UE and AP in certain period of time, for example, for AP, if currently without the auxiliary channel that can be used（All channels are taken by other AP）, then current AP can not support 40MHz communication bandwidth, similarly, if currently having the auxiliary channel that can be used（The channel is overlapping not with other AP main channel), then current AP can support 40MHz communication bandwidth. More than, application of the method for transmission data of the invention in 802.11 η versions is listed, but the present invention is not limited to this, for example, introducing higher throughput in 802.11ac versions（VHT, Very High Throughput) pattern can support highest 160MHz bandwidth, similarly for the UE with VHT abilities, its VHT characteristic supported is stated by VHT Capabilities cells, for example, if support 80MHz+80MHz or 160MHz channel width（Indicated by Supported Channel Width Set）, also, the channel width that AP can be supported is four kinds, i.e. 20 MHz, 40 MHz, 80MHz and 160MHz or the MHz of 80 MHz+80.In this case, for example, above-mentioned S110 and S1 can be replaced by VHT Capabilities²The HT Capabilities used in 0, in addition to the channel width finally determined there may be difference, other the step of and method it is similar with the application in 802.11 η versions, here, in order to avoid repeating, the description thereof will be omitted.

If in addition, for example, being provided only with one in system（Or it is a small amount of）Α Ρ, then there may be no matter any time Α Ρ can provide main channel and the situation of auxiliary channel to UE, now, UE and Α Ρ can consult the version communicated each other（For example, any version in 802.11a/b/g, 802.11 η or 802.11ac）And report base station, so as to, base station can be according to the versions of present communications, determine bypass flow, for example, if communications version is 802.11a/b/g, then base station can determine that the channel width communicated between UE and AP is 20 MHz, if communications version is 802.11 η, then base station can determine that the channel width communicated between UE and AP is 40 MHz, if communications version is 802.11ac, and base station can determine that the channel width communicated between UE and AP is 80MHz or higher.Or, UE and AP can also report the version that it is supported respectively, so as to which base station can be according to version relatively low in the two, determine the channel width communicated between UE and AP, if for example, UE only supports 802.11a/b/g, and 802.11a/b/g, 802.11 η and 802.11ac whole are supported in base station, the version then supported using UE is foundation, it may be determined that the channel width communicated between UE and AP is 20 MHz.

After the flow of shunting is determined, base station needs to notify AP and target UE to carry out shunting and prepare.

Alternatively, at this according to the channel width, via the GTP tunnel, before the transmission by the WLAN AP and user equipment progress target data, this method also includes：

First, which is sent, to the WLAN AP shunts configured information, the first shunting configured information is used to indicate that the WLAN AP transmit data between the base station and the user equipment, the first shunting configured information includes the identity information of the user equipment, wherein, an identity information is used to uniquely indicate a user equipment in the communication system.

Specifically, base station sends first to AP and shunts configured information, and the first shunting configured information can To indicate that AP needs the data that base station is sent to it being sent to target UE, it also can indicate that AP needs the data that target UE is sent to it being sent to base station, wherein, the first shunting configured information can be sent to AP with the identity information of target UE, wherein, an identity information can uniquely indicate a user equipment in systems.

The identity information can include following any information：

MAC Address, Internet protocol IP address, BSSID BSSID, association identity information AID, mobile subscriber cellphone number, IMSI International Mobile Subscriber Identity IMSI or International Mobile Station Equipment Identity IMEI.

Specifically, in embodiments of the present invention, the identity information of equipment refers to that the information of the equipment can be uniquely identified in the communication system using the embodiment of the present invention.It should be noted that in embodiments of the present invention, the identity information can the information that carries when dispatching from the factory of equipment or system be that equipment distribute, it is of the invention to be simultaneously not particularly limited.

In embodiments of the present invention, identity information can include medium education（MAC, Medium Access Control) address, Internet protocol（IP, Internet Protocol) address, BSSID（BSSID, Basic Service Set IDentifier), associate identity information（AID, Association IDentifier), mobile subscriber cellphone number, IMSI International Mobile Subscriber Identity（IMSI, International Mobile Subscriber Identity) and international mobile station equipment mark mouthful,（IMEI, International Mobile Equipment Identity) etc. information.It should be understood that user's mark of the embodiment of the present invention is not limited to information above, other cells that can uniquely embody user's mark are each fallen within the range of the embodiment of the present invention.

The AP can be according to the identity information of the target UE, determine the target UE, and, can be according to the first shunting configured information, it is determined that needing the data that base station is sent to it being sent to target UE, or, it is determined that needing the data that target UE is sent to it being sent to base station.

When transmitting data by wireless LAN communication mode due to AP and target UE, need to know the MAC Address of target UE, therefore, AP can also be it is determined that after the target UE, obtain the MAC Address of the target UE, for example, can be from the mobility management entity (MME in system, Mobility Management Entity) obtain the MAC Address of the target UE, the MAC Address of the target UE can also be obtained from the target UE, the MAC Address of the target UE can also be obtained from base station, the present invention is simultaneously not particularly limited.

In addition, in embodiments of the present invention, user equipment can be by its MAC Address, for example, by attach request（Attach Request) or tracing section updating request（Tracking Area Update Request) message is carried to MME, so that, MME can be by the MAC Address of user equipment for example, by UE Initial context is set up（Initial UE Context Setup Request) or UE context modification messages (UE Context Modify Request) be handed down to base station so that, base station can obtain the MAC Address of each user equipment.

Also, base station can be set up for example, by UE connections and ask（UE Association Setup Request) message, by the GTP tunnel terminal iidentification (TEID corresponding with the target UE of base station side, Tunnel Endpoint Identifier) it is sent to AP, and, can be for example, by UE connection establishment responses（UE Association Setup Response) message sink AP send AP sides the GTP TEID corresponding with the target UE.So as to which a base station side GTP TEID can identify a up GTP tunnel（The GTP tunnel used when transmitting data from AP to base station）, an AP sides GTP TEID can identify a descending GTP tunnel（The GTP tunnel used when transmitting data from base station to AP）.

Alternatively, the base station carries out the transmission of target data by the WLAN AP and the user equipment via the GTP tunnel, including：

The base station determines first GTP tunnel corresponding with the user equipment；

The base station carries out the transmission of target data by the WLAN AP and the user equipment via first GTP tunnel.

Specifically, the UE only one of which shunted if necessary by AP, the transmission of target data then can be directly carried out by each GTP tunnel, but, it is two or more if necessary by the AP UE shunted, or be currently accessed AP UE for two or more, then need to make between base station and AP, determine the mapping relations between each GTP and each UE.So as to for example, when base station is needed by AP to user equipment（Hereinafter, for the ease of differentiation, referred to as target UE）Send data（That is, downlink data）When, the GTP tunnel corresponding with the target device can be passed through（Specifically, it is downlink tunnel）The downlink data is sent to AP（Down target data）, AP can according to received data via tunnel, it is to need to be sent to the down target data of target UE to determine the data.For another example after AP receives the data of target UE transmission, can be according to the above-mentioned first shunting configured information, it is to need to be sent to the data of base station to determine the data（Up target data）, so that, AP can select the GTP tunnel corresponding with the target UE（Specifically, it is uplink tunnel）, and by the GTP tunnel, up target data is sent to base station, base station can according to received data via tunnel, it is the up target data from target UE to determine the data.

Alternatively, the base station determines first GTP tunnel corresponding with the user equipment, including： The base station determines up first GTP tunnel corresponding with the user equipment；

The base station sends the first mapping relation information to the WLAN AP, and first mapping relation information is used to indicate the mapping relations between the Tunnel Identifier TEID and the user equipment of up first GTP tunnel；And
