Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for transmitting data. Background technique

With the development of mobile communication systems, the transmission rate and quality of service that the system can provide are getting higher and higher, and the user service is also placing higher and higher requirements on the transmission rate. In order to ensure the general configuration without greatly increasing the configuration bandwidth. The user's rate, while providing a higher throughput for some users, the 3GPP introduced the Carrier Aggregation (CA) technology. The carrier aggregation technology UE (User Equipment) can use multiple CCs (Component Carrier, The component carrier) performs uplink and downlink communication to support high-speed data transmission. Among them, according to the type of carrier to be aggregated, it is divided into two types: carrier aggregation of the same system and carrier aggregation of different systems. Carrier aggregation in different systems refers to that the carrier used by one UE belongs to different systems, such as LTE (Long Term Evolution) + UMTS (Universal Mobile Telecommunications System), or LTE+WiFi (wireless Fidelity, wireless). Fidelity, or UMTS+WiFi, etc. This type of carrier aggregation can take full advantage of the characteristics of various communication systems to achieve efficient and low-cost transmission.

In the prior art, a carrier aggregation method for different systems is provided. When a service is established, the network side selects a system according to the current load situation, and establishes a bearer on the system to transmit the data packet of the service. When the system cannot meet the QoS (Quality of Service) of the data, the transmission of the data needs to be relocated to another system. At this time, the CN (Core network) initiates the bearer to the existing system bearer. Delete request, will be in the original After the bearer in the system is deleted, a bearer setup request is initiated to another system to establish a new bearer in another system, and the data packet is transmitted in the new system to improve the QoS of the data.

It can be seen from the above process that after the bearer of the access layer is established in the prior art, if the bearer needs to be replaced into another access layer system, the bearer can only be triggered by the CN side, and then at another access layer. A new radio bearer is re-established in the system, which involves the participation of the CN side. The process is complicated. When the service data rate fluctuates, the bearer cannot be quickly replaced or relocated according to the data volume to the target node. Summary of the invention

Further, the base station selects a WIFI node in the WIFI node that establishes a data plane channel with the base station.

In this embodiment, when the source access network node is a WIFI node and the target node is a base station, the scheme for pre-configuring the base station of the WIFI node is as follows:

Generally, one WIFI node corresponds to one base station, and the WIFI node can select the base station as a pre-configured target node. In another case, when the WIFI node corresponds to a different cell, when the cell ranges overlap, the WIFI node may further select a base station corresponding to the cell with light load sharing, or select a cell corresponding to a cell with a large capacity or a good signal quality. The base station is not limited by the present invention. Optionally, the method further includes:

In this embodiment, the BSR occupies 6 bits and can represent 64 different code points, each of which has a certain meaning. The amount of data reported by the UE to the base station must be within a certain range, and the amount of data beyond this range can only be represented by a unique code point. For example, when the data volume is 0-100 bytes, the reported BSR value is 0. When the data volume is 100-300 bytes, the reported BSR value is 1. When the data volume is 300-600 bytes, the BSR value of the upper limit is 2. When the amount of data is greater than 1000 Bytes, the reported BSR value can only be 63, regardless of the amount of real data that the UE needs to report to the eNB.

In this embodiment, the participation of the CN is not required, and the complexity of the process is reduced, so that when the service data rate fluctuates, the bearer can be quickly replaced according to the data rate, and the QoS of the data transmission is improved.

Referring to FIG. 2, in this embodiment, a method for transmitting data is provided. In this embodiment, the source node is a WIFI node, and the target node is a base station. In the scenario of the cross-system carrier aggregation, when the access point of the WiFi is set up for a certain UE, if the network side configures the bearer of the LTE access system for the UE at the same time, the ID of the corresponding base station is used. (identity, identity number) is notified to the WiFi access point, where the number of the base stations may be one or more, which is not specifically limited in this embodiment. The WiFi access point may be stored in the form of a list of the base stations that are pre-configured, and may be stored in other forms, which is not specifically limited in this embodiment. It is worth noting that during the communication process, if the base station associated with the UE changes, the network side also needs to notify the WiFi access point of the change of the base station, so that the WiFi access point updates the relevant base station list. Optionally, in this embodiment, the base station bearer status may be updated periodically in the base station list, so that the WiFi access point can select the corresponding relocation target node according to the bearer situation of the base station.

The specific method for transmitting data provided in this embodiment includes:

201. The WiFi access point determines whether the data of the service to be transmitted needs to be relocated, and if yes, select at least one target node for relocation in the pre-configured base station.

In this embodiment, the WiFi access point acquires the QoS of the data transmitted by the system in real time. When the WiFi access point finds that the WiFi system cannot meet the QoS of the data, the delay of the data packet cannot meet the transmission standard, or the downlink data is accumulated. If the threshold is exceeded, it is confirmed that the data of the service to be transmitted needs to be relocated.

In this step, when it is determined that the data to be transmitted needs to be relocated, the WiFi access point is from One or more base stations are selected as the target node for relocation in the locally stored base station list, and an RB relocation request is sent thereto, requesting the base station to bear wireless transmission of data on its behalf. The WiFi access point may select any one or more base stations in the base station list as the target node for relocation, or select one or more base stations as the target of relocation according to the bearer capability of the current base station in the base station list. The node is not specifically limited in this embodiment.

In this embodiment, if the WiFi access point does not need to be relocated, the data is continuously transmitted, which is not described in this embodiment.

202. Send a relocation request message to the selected base station.

In this step, the relocation request message is sent to the selected base station, where the relocation request message includes: a Qos request for the service data to be transmitted and a number of data packets required to be transmitted by the base station, where the number includes the downlink data. The number of packets and the number of packets of upstream data.

Optionally, the relocation request message includes: a Qos request for the service data to be transmitted and a time length t required for the base station to transmit the data, that is, when the base station receives the request message, and replaces the air interface data for the time t.

It should be noted that, in this embodiment, if the service needs to be permanently relocated to another system, the relocation request may be indicated. In this case, the relocation request message includes: The QoS requirement of the data does not limit the number of data packets to be transmitted or the time to be transmitted. Thus, after receiving the relocation request, the base station permanently relocates the service to the local device until the service data transmission is completed. Optionally, information confirming the permanent relocation of the transmission data of the UE to the target node may also be set in the relocation request message. The relocation request message at this time includes: a Qos request for the service data to be transmitted and information for confirming relocation of the transmission data of the UE to the target node. In the specific implementation process, what content is included in the relocation request message may be determined according to actual transmission requirements, which is not specifically limited in this embodiment.

The steps 201-202 are performed by the source access network node selecting a target node among the pre-configured nodes, and sending a relocation request message to the target node, where the relocation request message is used. And the step of relocating data of the source access network node to be transmitted to the target node.

203. When receiving a response message of the relocation request returned by the base station, notify the UE of the node information of the base station.

In this embodiment, after receiving the relocation request message, the base station determines whether it can still bear the service to be transmitted according to the service that is currently carried by the base station, and if yes, returns a response message of the relocation request to the WiFi access point. After receiving the response message returned by the base station, the WiFi access point informs that the data of the UE to be transmitted has been shared to the base station for transmission, and transmits the node information of the base station to the UE. The node information of the base station includes but is not limited to a base station ID.

In this embodiment, if the base station determines that it cannot bear the service to be transmitted, it returns a message rejecting the relocation request to the WiFi access point, so that the WiFi access point reselects other nodes except the base station to perform relocation. At this point, the WiFi access point returns to step 201 to re-execute its relocation process.

204. The UE establishes a connection with the base station according to the node information of the base station, and performs data transmission.

In this embodiment, after receiving the node information of the base station, the UE requests to establish an RB (Radio Bearer) in the air interface with the base station. After receiving the request message, the base station establishes an RB with the UE in the air interface to perform data transmission. The UE does not need to record the corresponding core network information, and only needs to know the information of the base station. The process of establishing a connection between the UE and the base station is similar to the prior art, and is not described in this embodiment.

In this embodiment, the data transmission process after relocating the service to be transmitted is as follows:

1) For the downlink data, the CN sends the downlink data to the WiFi access point, and the WiFi access point transfers the downlink data to the base station, and the base station sends the downlink data to the UE;

2) For the uplink data, the UE sends the uplink data to the base station, and the base station sends the data to the WiFi access point, and the WiFi access point sends the uplink data to the CN.

It is to be noted that, in the embodiment, after the node information of the base station relocated by the user equipment UE is notified in step 203, the method further includes: notifying the CN information of the relocated base station to the CN, so that the CN is Data describing the transmission service is sent to the base station. In this way, CN, base station and Data can be directly transmitted between UEs without the need for WiFi access point forwarding.

Step 203-204 is performed by the source access network node transmitting the node information of the target node to the user equipment UE, so that the UE establishes a connection with the target node according to the node information of the target node, and performs the The step of referring to the data transmission of the transmission service.

Referring to FIG. 3, in this embodiment, a method for transmitting data is provided. In this embodiment, the source node is a base station, and the target node is a WIFI node. The relocation of the to-be-transmitted service in this embodiment is triggered by the base station on the LTE side. Before the base station on the LTE side performs the relocation process, the base station is configured with one or more related WiFi access points, so that when the relocation needs to be performed, the base station can select an appropriate node from the pre-configured WiFi access points. The target node to be relocated to the transport service. The base station may store the pre-configured WiFi access point in the form of a list, and may also be stored in other forms, which is not specifically limited in this embodiment. In this embodiment, one or more related WiFi access points configured for the base station may be changed according to requirements, and the change of the WiFi access point is notified to the base station, so that the base station can update the WiFi access point list in time. Optionally, in this embodiment, the WiFi access point bearer may be periodically updated in the WiFi access point list, so that the base station can select a corresponding relocation target node according to the bearer situation of the WiFi access point.

The specific method for transmitting data provided in this embodiment includes:

301. The base station determines whether the data of the service to be transmitted needs to be relocated, and if yes, select one or more target nodes for relocation in the pre-configured WiFi access point.

In this embodiment, the base station obtains the QoS of the data transmitted by the system in real time. When the base station finds that the LTE system cannot meet the QoS of the data, if the downlink data waiting to be sent in the buffer is too much, and exceeds a predetermined threshold, it is required to confirm Relocate the data of the service to be transmitted.

In this embodiment, the process of the base station triggering the relocation may be because the LTE system cannot find the QoS of the data, or may be the BSR of the preset format reported by the base station. In this embodiment, when the base station receives the BSR reported by the UE, it determines whether the received BSR is in the preset format. The BSR, if yes, confirms that the data of the to-be-transmitted service needs to be relocated. The BSR in the preset format is used to indicate that the data to be transmitted in the UE exceeds a preset threshold. After receiving the BSR in the preset format, the base station learns that the BSR needs to be relocated.

In this embodiment, a BSR format is redefined. The BSR in the preset format may include multiple BSR values, that is, two or more BSR values, where each BSR value may be the same value or a different value. This embodiment is not specifically limited. Optionally, the BSR value may be the same as the existing BSR value, or may be completely different from the existing BSR value, which is not specifically limited in this embodiment.

When the uplink data of the UE exceeds the preset number, multiple BSR values can be sent in the same MAC PDU. When the base station receives multiple BSR values in the same MAC PDU, it can confirm that the BSR of the preset format is received.

Optionally, multiple BSR values may be sent in a preset time interval. When the base station receives multiple BSR values within a preset interval, the BSR is confirmed to receive the preset format. For example, a normal BSR value may be sent, for example, a BSR value of 63, and a BSR with a value of 0 is sent in a preset interval. When the base station receives the above two BSR values within a preset interval, Then confirm that the BSR of the preset format is received.

In this step, when determining that the data to be transmitted needs to be relocated, the base station selects one or more WiFi access points from the locally stored WiFi access point list as the retargeting target node, and sends a relocation request to the base station. , requesting the WiFi access point to undertake wireless transmission of data on its behalf. The base station may select any one or more WiFi access points in the WiFi access point list as the target node for relocation, or select one according to the carrying capacity of the current WiFi access point in the WiFi access point list. The multiple access points of the WiFi access point are used as the target node for relocation, which is not specifically limited in this embodiment.

In this embodiment, if the base station does not need to be relocated, the data is continuously transmitted, which is not described in this embodiment. 302. Send a relocation request message to the selected WiFi access point.

In this step, the relocation request message is sent to the selected WiFi access point, where the relocation request message includes: a Qos request for the service data to be transmitted and a number of data packets that need to be transmitted by the WiFi access point. The number includes the number of packets of downlink data and the number of packets of uplink data.

Optionally, the relocation request message includes: a QoS requirement of the service data to be transmitted and a length of time t required for the WiFi access point to transmit data, that is, when the request message is received from the WiFi access point, at time t The inner generation is the transmission air interface data.

It should be noted that, in this embodiment, if the service needs to be permanently relocated to another system, the indication may be performed in the relocation request. Optionally, the relocation request message includes: The QoS request does not limit the number of data packets to be transmitted or the time to be transmitted. In this way, after receiving the relocation request, the WiFi access point permanently relocates the service to the local device until the service data transmission is completed. Optionally, information confirming the permanent relocation of the transmission data of the UE to the target node may also be set in the relocation request message. The relocation request message at this time includes: a Qos request for the service data to be transmitted and an information for confirming that the transmission data of the UE is permanently relocated to the target node, and the transmission data includes the data of the service to be transmitted. In the specific implementation, the content of the relocation request message may be determined according to the actual transmission requirement, which is not specifically limited in this embodiment.

The step 301-302 performs that the source access network node selects the target node in the pre-configured node, and sends a relocation request message to the target node, where the relocation request message is used to access the source. The step of relocating data of the service to be transmitted by the network node to the target node.

303. When receiving a response message of the relocation request returned by the WiFi access point, notify the UE of the node information of the WiFi access point.

In this embodiment, after receiving the relocation request message, the WiFi access point determines whether it can still bear the service to be transmitted according to the service that is currently carried by the WiFi access point, and if yes, returns a response message of the relocation request to the base station. After receiving the response message returned by the WiFi access point, the base station passes It is known that the data of the UE to be transmitted is shared to the WiFi access point for transmission, and the node information of the WiFi access point is sent to the UE. The node information of the WiFi access point includes, but is not limited to, ID information of the WiFi access point.

In this embodiment, if the WiFi access point determines that it cannot bear the service to be transmitted, it returns a message rejecting the relocation request to the base station, so that the base station reselects other nodes except the WiFi access point for relocation. At this time, the base station returns to step 301 to perform the relocation process again.

304. The UE establishes a connection with the WiFi access point according to the node information of the WiFi access point, and performs data transmission.

In this embodiment, after receiving the node information of the WiFi access point, the UE can establish a connection with the target WiFi access point after the underlying access handshake process, thereby performing data transmission. The UE does not need to record the corresponding core network information, and only needs to know the information of the WiFi access point. The process of establishing a connection between the UE and the WiFi access point is similar to the prior art, and is not described in this embodiment.
