Description

Data transmission method, user equipment and base station

Technical field

The present invention relates to communication technologies, and in particular, to a data transmission method, a user equipment, and a base station. Background technique

At present, the cooperation between the 3rd Generation Partnership Project (3GPP) network and the non-3rd generation partner program network has become a hot topic of current research. For example, a cooperation between a Long Term Evolution (LTE) network and a Wireless Local Area Networks (WLAN) network device enables a User Equipment (UE) to work under an LTE network while passing through a wireless local area network. A Wireless Local Area Networks Access Point (WLAN AP) is connected to the WLAN network. Here, the cellular networks of various standards such as LTE, GSM, and CDMA are referred to as a first-standard network, and the wireless local area network WLAN is referred to as a second-standard network.

In the prior art, the AP/UE obtains resources for transmitting downlink/uplink data frames or management frames in a contending manner in the WLAN network. Taking the uplink data sent by the UE as an example, the competition process is: When the UE hears that the channel state is idle, the UE waits for an Interframe Spacing (IFS) first, and then, in the 0~Contention Window (CW). Select a random avoidance time to avoid collision; start the timer while selecting the random avoidance time; wait if the channel status is busy. In the idle state, when the timer time is decremented to 0, if the channel status is still idle, the uplink data is transmitted. In this process, if multiple UEs/APs select the same random backoff time, a collision occurs. After the collision, the UE continues to re-competing resources after doubling the CW (up to CWmax). Data loss occurs when the number of retries exceeds the maximum number of limits. The number of uplink and downlink data packets in the WLAN is about 1:1.3, and most of the uplink data packets are small packets. For example, 90% of the Transmission Control Protocol (TCP) packets are 40 to 80 Byte packets, and the uplink user data is used. The User Datagram Protocol (UDP) is also mainly concentrated below 200 bytes. It can be seen that the uplink data packet in the WLAN is mainly a small packet, and the number of packets is large. If a plurality of UEs send uplink data, the random avoidance time selected by multiple UEs is the same due to the random selection of the avoidance time, and the probability of collision of the uplink data packet is greatly increased, so that the service quality is improved. The amount is not guaranteed.

Therefore, how to avoid the uplink transmission collision when transmitting the uplink WLAN information to ensure the quality of the service is an urgent problem to be solved in the industry.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of Embodiment 1 of a data transmission method according to the present invention. The embodiments of the present invention are described in detail from the perspective of a user equipment, and the embodiments of the present invention are applicable to a cellular network and

In a scenario where the WLAN network is merging, the WLAN information sent by the UE to the AP needs to be forwarded through the cellular network, and the scenario in which the probability of collision of the uplink transmission in the WLAN is reduced is achieved by reducing the uplink transmission in the WLAN. Specifically, the embodiment includes the following steps:

101. The user equipment determines whether the WLAN frame of the access point AP that is sent to the WLAN WLAN needs to be forwarded by the base station.

The wireless communication system in the embodiment of the present invention includes a base station providing a cellular network and an access point providing a wireless local area network, and further may further include a user equipment. The user equipment transmits uplink data to the core network through the cellular network and the WLAN. Before the user equipment sends a WLAN frame to the transmitting AP, it needs to determine whether the WLAN frame needs to be forwarded through the base station. For example, if the user equipment receives the forwarding indication information sent by the base station, it determines that the WLAN needs to be forwarded by the base station; for example, if the user equipment determines that its performance status or the performance status of the AP exceeds the forwarding threshold, it determines the need. The WLAN is forwarded by the base station.

Optionally, after determining that the WLAN frame needs to be forwarded by the base station, the user equipment may first encapsulate the WLAN frame in the form of a radio frame. Specifically, when the cellular network is a Global System for Mobile Communications (GSM) network, the WLAN frame may be encapsulated into a GSM radio frame, and when the cellular network is an LTE network, the WLAN frame may be encapsulated into an LTE radio frame. . The radio frame obtained after the encapsulation carries the indication information sent to the WLAN, and the indication information sent to the WLAN is used to indicate that the base station needs to extract the WLAN frame and send the WLAN frame to the AP.

The WLAN frame sent by the user equipment to the AP includes three types: a data frame, a management frame, and a control frame. The management frame is, for example, an Association Request Frame (ARF), a Reassociation Request Frame (RRF), a Probe Request Frame (PRF), an Authentication Frame (AF), and the like. If the management frames collide with each other, the authentication of the user equipment fails, and the AP cannot respond or manage the user equipment in time, so that the quality of the service cannot be guaranteed. In addition, the management frame is easily sent to the sender of the management frame. The downlink data, or the uplink data sent by other user equipments to the AP, collides, and the quality of the service is not guaranteed. Data frames are prone to collisions due to the large amount of packet data, which makes the quality of the service unguaranteed. Compared to management frames and data frames, control frames require strong interactivity and shorter waiting time in resource contention, such as just waiting for Short Inter Frame Spacing (SIFS). Therefore, in this embodiment, the WLAN frame includes: a management frame and/or a data frame, and the control frame is sent in a resource competition manner in the prior art.

102. If the user equipment determines that the WLAN frame needs to be forwarded by the base station, sending the WLAN indication information and the WLAN frame to the base station, where the WLAN indication information is used to indicate that the base station is to be The WLAN frame is sent to the AP.

After determining that the WLAN frame needs to be forwarded by the base station, the user equipment sends the WLAN indication information and the WLAN frame to the base station. For example, after encapsulating the WLAN frame, the user equipment sends the encapsulated cellular radio frame to the base station. The base station stores the corresponding relationship between the user equipment and the AP. For example, the base station may pre-store the correspondence between the user equipment and the AP, or acquire the corresponding relationship between the UE and the AP in advance and store the information. Therefore, after receiving the WLAN indication information and the radio frame, the base station extracts the WLAN frame in the cellular radio frame according to the WLAN indication information, and sends the WLAN frame to the corresponding AP according to the corresponding relationship between the user equipment and the AP.

In the data transmission method provided by the embodiment of the present invention, before transmitting the WLAN frame to the AP, the user equipment determines whether the WLAN frame needs to be forwarded by the base station, and after transmitting the WLAN frame that needs to be sent to the AP, the WLAN indication information is sent to the base station. And the WLAN frame, so that the base station forwards the WLAN frame to the AP. In this process, the user equipment does not need to select the random backoff time, but forwards the WLAN information sent by the UE to the AP through the cellular network, and reduces the probability of collision of the uplink transmission in the WLAN by reducing the uplink transmission in the WLAN, thereby improving the service. quality.

Optionally, in the first embodiment, after receiving the forwarding indication information sent by the base station, the user equipment determines, according to the forwarding indication information, that the WLAN frame is forwarded by using the base station.

Further, optionally, in the foregoing Embodiment 1, the user equipment receives the transfer sent by the base station. After the indication information is sent, the stop forwarding indication information sent by the base station is further received, where the stop forwarding indication information is used to instruct the user equipment to stop forwarding the WLAN frame by using the base station. Then, the user equipment stops forwarding the WLAN frame through the base station according to the stop forwarding indication information.

Optionally, in the first embodiment, the user equipment may first receive a forwarding threshold sent by the base station, where the forwarding threshold indicates a performance status of the user equipment and/or the AP when the user equipment needs to forward the WLAN frame by using the base station. Then, the user equipment determines whether the performance status and the forwarding threshold of the current and/or AP meet the preset rule. If yes, the WLAN frame is forwarded by the base station.

Optionally, in the first embodiment, the user equipment further receives a stop forwarding threshold sent by the base station, where the stop forwarding threshold indicates that the user equipment needs to stop performing performance of the user equipment and/or the AP when the WLAN frame is forwarded by the base station. Then, the user equipment determines whether the performance status of the current self and/or the AP and the stop forwarding threshold meet the preset rule, and if yes, stops forwarding the WLAN frame by the base station. In this process, the base station can simultaneously send the stop forwarding threshold and the forwarding threshold to the user equipment, or send the forwarding threshold first and then send the stop forwarding threshold.

Optionally, in the foregoing Embodiment 1, when the number of the APs is multiple, the WLAN indication information sent by the user equipment to the base station may further carry the AP identifier, where the AP identifier is used to indicate that the base station sends the WLAN frame to the AP identifier. AP. The AP identifier may be, for example, a Service Set Identifier (SSID), a Basic Service Set Identifier (BSSID), or the like.

FIG. 2 is a flowchart of Embodiment 2 of a data transmission method according to the present invention. The embodiment of the present invention is a detailed description of the present invention from the perspective of a base station. The present embodiment is applicable to a scenario in which a WLAN information is transmitted to a AP through a cellular network, and the WLAN information in the WLAN is reduced. The uplink transmission achieves a scenario of reducing the probability of collision of uplink transmissions in the WLAN. Specifically, the embodiment includes the following steps:

201. The base station receives the WLAN indication information and the WLAN frame sent by the user equipment, where the WLAN indication information is used to instruct the base station to send the WLAN frame to the access point AP.

The user equipment sends the WLAN indication information and the WLAN frame to the base station when determining that the WLAN frame of the access point AP that needs to be sent to the WLAN is transmitted through the base station; correspondingly, the base station receives the WLAN indication information and the WLAN frame. For details, refer to Figure 1, which is not described here.

Optionally, the WLAN frame includes: a management frame and/or a data frame, and the control frame uses an existing technology. The in-process resource competition mode is sent. For details, refer to step 101 in Figure 1 above, and details are not described herein.

202. The base station forwards the WLAN frame to the AP according to the WLAN indication information.

After receiving the WLAN frame, the base station sends the WLAN frame to the AP according to the WLAN indication information. For example, the base station may pre-store the correspondence between the user equipment and the AP, or acquire the corresponding relationship between the UE and the AP in advance and store it. Therefore, after receiving the WLAN frame, the base station sends the WLAN frame to the AP according to the correspondence between the user equipment and the AP.

In the data transmission method provided by the embodiment of the present invention, after receiving the WLAN indication information and the WLAN frame sent by the user equipment, the base station sends the WLAN frame to the AP according to the WLAN indication information that is sent to the AP. In this process, the user equipment does not need to select the random backoff time, but forwards the WLAN information sent by the UE to the AP through the cellular network, and reduces the probability of collision of the uplink transmission in the WLAN by reducing the uplink transmission in the WLAN, thereby improving the service. quality.

Optionally, in the foregoing Embodiment 2, before receiving the WLAN frame carrying the WLAN indication information of the wireless local area network, the base station further sends forwarding indication information to the user equipment, where the forwarding indication information indicates that the user equipment forwards the WLAN frame by using the base station.

Specifically, since the base station can provide services for multiple user equipments at the same time, the base station stores state information, importance level, load status, and the like of each user equipment. Therefore, the base station can preset the threshold according to the performance status of the AP and/or the user equipment, and determine the transmission mode of the WLAN frame by itself, that is, determine which WLAN frames of the user equipment are forwarded by the cellular network, and which WLAN frames of the user equipment are in the prior art. The way the resources compete is sent. For the user equipment whose WLAN frame is forwarded by the cellular network, the base station sends forwarding indication information to the user equipment, thereby triggering the user equipment to forward the WLAN frame sent to the AP through the base station.

In addition, the base station may also send the user equipment and/or the forwarding threshold of the performance of the user equipment to the user equipment when the user equipment needs to forward the WLAN frame through the base station, so that the user equipment determines the performance status of the AP according to the forwarding threshold. And/or, whether the performance status and the forwarding threshold of the self satisfy the preset rule, so as to determine whether the WLAN frame sent to the AP needs to be forwarded through the base station. Optionally, when the forwarding threshold is the performance status of the AP, the forwarding threshold includes at least one of the following thresholds: a maximum threshold of the user equipment accessing the AP, a maximum specific gravity threshold of the busy channel of the AP, and a forwarding threshold indication. When the performance status of the user equipment is used, the preset threshold includes at least one of the following thresholds: a maximum collision probability threshold of the user equipment competing channel, and the user equipment receives the data packet. The maximum error rate threshold.

Specifically, the AP periodically broadcasts a beacon frame (BF), and the beacon frame carries information such as the number of user equipments currently accessed by the AP and the proportion of the busy channel of the AP. When the forwarding threshold is the maximum number of user equipments that access the AP, the user equipment compares the number of user equipments in the beacon frame with the maximum number of user equipments that access the AP, and the number of user equipments that are accessed. For an AP that exceeds the maximum number of thresholds, the user equipment encapsulates the WLAN frame sent to the AP into a radio frame, which is forwarded by the cellular network, and ignores the AP whose number of accessed user equipment does not exceed the maximum number of thresholds. For example, the maximum number of user equipments that can be set to access the AP is 10, and if the number of user equipments currently accessed by the AP is greater than 10, the AP is overloaded, and the user equipment needs to transmit the WLAN frame to the AP by the cellular. If the number of user devices that have been accessed is less than 10, the WLAN frame sent to the AP is performed by using the prior art.

When the forwarding threshold is the maximum specific gravity threshold of the AP's busy channel, the user equipment compares the proportion of the busy channel of the AP in the beacon frame with the maximum specific gravity threshold of the AP's busy channel, and the proportion of the busy channel exceeds the maximum specific gravity threshold. The AP, the user equipment encapsulates the WLAN frame sent to the AP into a radio frame, and then forwards it by the cellular network, and ignores the AP whose proportion of the busy channel does not exceed the maximum specific threshold. For example, the maximum specific gravity threshold can be set to 90%. If the busy channel proportion of the AP is greater than 90%, the AP is overloaded, and the user equipment needs to forward the WLAN information sent to the AP by the cellular network, if the AP's busy channel proportion If it is less than 90%, the WLAN information sent to the AP is performed by using the prior art.

When the forwarding threshold is the maximum backhaul link capacity threshold of the AP, the user equipment can pass

The Access Network Query Protocol (ANQP) mechanism of the Hotspot 2.0 protocol requests the AP to obtain backhaul related information. For example, when the maximum backhaul link capacity threshold is 100 Mbps, and the user equipment learns that the current backhaul link capacity is 50 Mbps through the ANQP mechanism, that is, the current backhaul link capacity is less than the maximum backhaul link capacity, the user equipment considers the WLAN frame sent to the AP. It is carried out using the prior art. On the other hand, if the current backhaul link capacity is greater than or equal to 100 Mbps, the user equipment considers that the WLAN frame addressed to the AP needs to be forwarded by the cellular network.

When the maximum threshold is the maximum collision probability threshold of the user equipment contending channel, the user equipment collects the collision probability of the contending channel. If the statistic conflict probability exceeds the maximum collision probability threshold, the user equipment stops sending uplink service data through the AP. If the statistical collision probability does not exceed the maximum collision probability threshold, the uplink service data is continuously sent through the AP. User equipment through basic transmission The data transmission is performed by the transmission mode and the four-step handshake mode. When the basic transmission mode is used, the user equipment directly sends data to the AP, and the AP replies with an acknowledgement (ACK). At this time, if the ACK of the AP feedback is not received within a given time after the user equipment sends the data, if the channel condition between the user equipment and the AP is worse than the certain condition, the channel condition is considered to be too poor. No ACK was received within the fixed time. On the other hand, if the channel condition is better than a certain condition, it can be considered that the collision does not result in the receipt of the ACK, and the user equipment counts the probability that the collision probability is the ratio of the total number of collisions to the total number of times the user equipment attempts to transmit data. When the four-step handshake mode is adopted, the user equipment sends a Request To Send (RTS), and the AP replies to the user equipment with a Clear To Send (CTS). After receiving the CTS, the user equipment sends data. Finally, the AP sends the data. The user device replies with an ACK In this process, if the user equipment does not receive the CTS fed back by the AP within a certain time after sending the RTS, or the user equipment sends the data after receiving the CTS, if the ACK of the AP feedback is not received within a given time. If the user equipment measures that the channel condition between the user equipment and the AP is worse than a certain condition, it is considered that the channel condition is too poor, and the ACK is not received within a given time. On the other hand, if the channel condition is better than a certain condition, it is considered that the collision occurs and the ACK/CTS is not received. The collision probability perceived by the user equipment is the ratio of the total number of collisions to the total number of times the user equipment attempts to transmit data.

When the forwarding threshold is the maximum packet error rate threshold of the user equipment receiving the data packet, the user equipment collects the packet error rate of the received data packet when receiving the downlink data.
