Description

Method, system and equipment for shunting processing

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method, a system, and a device for performing offloading processing.

Background

In recent years, WLAN (Wireless Local Area network) technology based on 802.11 standard is increasingly widely used. The WLAN technology is a very convenient data transmission system, and it uses the RF (radio frequency) technology to replace the old local area network formed by twisted copper (coax), so that the WLAN can use a simple access structure to let the user pass through it to achieve information portability.

Under the technology, data transmission of all nodes is on the same channel, and the problem of sending data collision among the nodes is introduced. To resolve collisions, 802.11 employs a CSMA/CA (carrier sense multiple access/collision avoidance) mechanism for contention avoidance. That is, the node contends for the channel before sending data each time, and if contending for the channel, the data is sent out; a backoff is performed for a period of time if there is no contention for the channel, and then contention is again performed.

At present, a base station only shunts all data of a user equipment to an Access Point (AP) (as shown in fig. 1) after receiving a shunting instruction issued by an ANDSF (shunt control node), and thus, cannot actively perform shunting processing.

In summary, the current base station cannot actively perform the shunting process.

Detailed Description

According to the method, the network side equipment judges whether the shunting processing is needed or not according to the received channel state information; and after determining that the shunting processing is required, notifying the specific user equipment to carry out shunting processing. According to the method and the device, the network side equipment judges whether to carry out shunting processing or not according to the received channel state information, and shunts the data of the user equipment, so that the network side equipment actively carries out shunting processing.

The shunting processing of the embodiment of the application comprises the following steps:

sending downlink data of the user equipment through the AP, and sending uplink data through network side equipment (see FIG. 2); or sending the downlink data of the user equipment through the network side equipment and sending the uplink data through the AP

In fig. 1, in a scenario where a base Station shunts data to an AP, if there are multiple STAs (stations, (or referred to as UEs) under one AP, since downlink data transmission of the AP needs to compete with multiple user equipments for channels, as the number of the user equipments increases or uplink traffic of the user equipments increases, the user equipments can seize the channels, thereby significantly reducing the probability that the AP competes for the channels, and causing a severe decrease in downlink throughput.

According to the embodiment of the application, the downlink data are sent through the AP, the uplink data are sent through the network side equipment, and due to the fact that the data of the user equipment are distributed, the probability of AP competition channels cannot be obviously reduced after the user equipment is increased or the uplink traffic of the user equipment rises, and therefore downlink throughput is guaranteed.

That is, the AP transmits data downstream faster than the network side device. When the number of UEs is too large, and uplink data or feedback is more in some services, a channel is used for uplink and downlink in a wireless fidelity (WIFI) transmission mechanism, and uplink feedback affects downlink data transmission. Therefore, the probability of channel occupation of the uplink UE can be reduced by distributing the uplink to the network side equipment. The system throughput of the AP is increased.

The embodiments of the present application will be described in further detail with reference to the drawings attached hereto.

As shown in fig. 3A, a first system for performing split stream processing according to an embodiment of the present application includes:

the network side device 30 is configured to determine whether to perform a offloading process according to the received channel state information; after determining that the shunting processing is needed, notifying specific user equipment to carry out shunting processing;

the method comprises the following steps that a first shunting processing mode is adopted, a specific user device is informed to send downlink data through an AP, and uplink data are sent through a network side device;

and in the second shunting processing mode, the downlink data is sent through the network side equipment, and the uplink data is sent through the AP.

Which shunting processing mode is specifically adopted can be set according to requirements. Only one type can be adopted, so that the user equipment is only required to be adjusted to carry out shunting processing.

Correspondingly, if the first shunting processing mode is adopted, the user equipment sends downlink data through the AP and sends uplink data through the network side equipment;

and if the second shunting processing mode is adopted, the user equipment sends the downlink data through the network side equipment and sends the uplink data through the AP.

In implementation, the channel state information received by the network side device may be reported by at least one AP or may be at least one user equipment; the reporting by the AP and the reporting by the user equipment may be both available.

If the channel state information received by the network side device is reported by the AP, as shown in fig. 3B, the embodiment of the present application may further include:

and the AP32 is configured to determine channel state information, and report the channel state information to the network side device, so that the network side device notifies the user equipment to perform offloading processing after determining that offloading processing is required according to the channel state information.

The following is a description of different reporting entities.

Firstly, reporting by user equipment.

In implementation, the network side device may trigger the ue to report, or the ue may decide whether to report. These two methods may be used alone or in combination.

If the network side equipment triggers the user equipment to report, specifically:

the network side equipment can periodically send a channel state request message to the user equipment; and/or sending a channel state request message to the user equipment after the triggering condition is met.

Wherein the trigger condition includes but is not limited to some or all of the following conditions:

Correspondingly, after the network side equipment is triggered, the user equipment reports the channel state information to the network side equipment.

If the user equipment determines whether to report, the user equipment can report the channel state information to the network side equipment by adopting part or all of the following modes:

firstly, the user equipment reports channel state information to the network side equipment periodically;

secondly, the user equipment reports the channel state information to the network side equipment after meeting the first reporting condition;

and thirdly, after receiving the channel state request message from the network side equipment, the user equipment reports the channel state information to the network side equipment.

Wherein, the first reporting condition includes but is not limited to part or all of the following conditions:

the data transmission delay exceeds a delay threshold value;

the user satisfaction QoE is lower than the satisfaction threshold value.

And secondly, reporting by the AP.

In implementation, the network side device may trigger the AP to report, or the AP may determine whether to report. These two methods may be used alone or in combination.

If the network side equipment triggers the AP report, specifically:

the network side equipment can periodically send a channel state request message to the AP; and/or sending a channel state request message to the AP after the triggering condition is met.

wherein, the abnormal condition includes but is not limited to part or all of the following conditions:

overload of an AP channel;

the AP data reception failure rate exceeds a fifth failure rate threshold.

In addition to the above-mentioned network side device determining whether to perform the offloading processing according to the received channel state information, after receiving the offloading instruction issued by the offloading control node ANDSF, it also needs to notify the user equipment to perform the offloading processing;

In implementation, when the network side device notifies the user equipment to perform offloading processing, if the user equipment which does not access the AP needs offloading processing, the network side device may also notify the user equipment to which AP the user equipment is to offload, for example, notify the user equipment of an identifier of the AP; for example, the UE is notified of an AP identifier with a short reporting distance and a good channel condition, and the network side device determines to access the AP from the reported identifier and notifies the user equipment; for example, the user equipment is notified of the AP identifier with a short access distance and a good channel condition, and the access AP identifier is reported. In addition to the above manners, any manner that enables the ue to find the AP is applicable to the embodiment of the present application.

If there are multiple APs, the network side device may select one AP as the offload AP. For example, one may be selected randomly. Preferably, the AP with good channel condition is selected according to the positions of the AP and the ue.

In implementation, after the network side device notifies the user equipment to perform the offloading processing, the network side device may also be notified to cancel the offloading processing when one of the following conditions is satisfied.

1. The distance between the UE and the AP exceeds a threshold;

2. the channel condition is below a threshold;
