Description

Service flow routing method and device

Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a service flow routing method and device.

Background technique

In recent years, with the development of the application of the Internet, and the advancement of broadband access technologies for mobile devices, notebooks and other terminal devices, especially wireless broadband access technologies, such as wireless fidelity (English: WIreless-Fidelity, referred to as: WiFi) access, Worldwide Interoperability for Microwave Access (WiMAX), third generation (English: 3rd-Generation, 3G for short) or fourth generation (Fourth Generation, 4G) mobile communication technology, etc. One user terminal is simultaneously provided with multiple paths to the target node. To this end, a multipath transfer control protocol (MPTP) is proposed, which allows a transmission control protocol (English: Transfer Control Protocol, TCP for short) to simultaneously transmit data through multiple paths.

The MPTCP technology implements the isolation between the application layer and the transport layer by adding an additional MPTCP sublayer above the TCP layer. The user can dynamically establish multiple substreams to implement multipath transmission of the application layer service at the transport layer. And load balancing, for example, using the 3rd Generation Partnership Project (English: 3rd Generation Partnership Project, 3GPP) and WIFI access for data transmission. In this type of transmission, when a specific access technology is required, for example, the WIFI access mode is used for transmission, and the 3GPP access mode is not used, the user equipment (English: User Equipment, UE for short) actively initiates the 3GPP access. The way the subflow is closed. When all the sub-streams of the 3GPP access mode are to be re-used, and the sub-stream of the subsequent 3GPP access mode needs to be reused, the UE needs to re-initiate the sub-flow establishment process of the corresponding 3GPP access mode for the service. After the establishment of the substream of the 3GPP access mode is completed, data transmission is performed on the substream of the established 3GPP access mode.

In the foregoing solution, when the 3GPP access mode is not required, the UE needs to initiate a sub-flow shutdown process of the 3GPP access mode, and directly close the sub-flow of the access mode, thereby causing sub-stream reconstruction when the re-use is required. In this way, the number of signaling processing of the UE and the server is increased.

Summary of the invention

The embodiment of the present invention provides a service flow routing method and device, which is used to solve the problem that when a 3GPP access mode is not required, the UE needs to initiate a 3GPP sub-flow shutdown process, and directly closes the sub-flow of the access mode, resulting in The method of substream reconstruction when reusing causes an increase in the number of signaling processes of the UE and the server.

A first aspect of the present invention provides a service flow routing method, where the method includes:

If the UE detects that the sub-flow of the second access mode can meet the transmission requirement of the service, the UE adjusts the sub-flow of the first access mode to an idle state, and sends a first indication message to the server; the first indication message is used. Instructing the UE to adjust the substream of the first access mode to an idle state;

The UE receives data transmitted by the server through the substream of the second access mode.

In this solution, the UE supports the transmission of the service data by using the first access mode and the second access mode, and the UE uses the sub-flows of the two access modes to transmit the service data, and detects one of the access modes. When the sub-flow can meet the transmission requirement, the UE adjusts the other access mode to the idle state, and sends a first indication message to the server, so as to adjust the sub-flow of the specific access mode without shutting down the sub-flow. It is idle and saves resources.

On the basis of the foregoing solution, the first access mode is used for the 3GPP access mode. The UE determines that the second access mode can meet the transmission requirements of all services according to the transmission requirements of the service, and then connects to the 3GPP that communicates with the UE. The server of the incoming sub-flow sends a first indication message, indicating that the sub-flow state of the 3GPP access mode is adjusted to an idle state, so that the server does not transmit the service data on the sub-stream of the 3GPP access mode, and the base station does not have a long time. The packet is detected, and the air interface resource release on the 3GPP side is initiated, so that the sub-flow of the 3GPP access mode is adjusted to the idle state without closing the sub-flow, and the cellular network air interface resource is saved.

Further, if the UE determines that the sub-flow of the first access mode needs to be used, the UE exits the idle state, and sends a second indication message to the server; the second indication message is used to indicate that the server can pass the first access mode. Flowing data to the UE;

The UE receives data transmitted by the server through the substream of the first access mode and the substream of the second access mode.

In this solution, the UE detects that the sub-flow of the second access mode cannot meet the transmission requirement of the service data, or the server initiates the request, and when the UE determines that the sub-flow of the first access mode is actually needed, The UE exits the idle state of the first access mode side, and sends a second indication message to the server of the first access mode that communicates with the server, indicating that the server can perform data transmission by using the sub-flow of the first access mode. The process of re-initiating the sub-flow of the first access mode is further reduced, and the number of processing signaling by the UE and the server is reduced, and the processing flow of the access mode state switching is optimized.

Optionally, the UE sends a second indication message to the server, including:

Transmitting, by the UE, the second indication message to the server by using the sub-flow of the first access mode;

or,

or,

In the above solution, when the UE sends the first indication message and the second indication message to the server, the UE may use any sub-flow of the access mode to send.

In the foregoing solution, the UE determines that the sub-flow of the first access mode needs to be used, including:

If the UE detects that the sub-flow of the second access mode cannot meet the transmission requirement of the service, determine that the sub-flow of the first access mode needs to be used;

or,

The UE receives the request message sent by the server, and the request message is used to request to use the sub-stream of the first access mode to transmit data, and after receiving the request message, the UE determines that the sub-flow of the first access mode needs to be used;

or,

The UE receives the request message sent by the server; the request message is used to request to use the sub-stream of the first access mode to transmit data; and the UE determines whether the sub-flow of the first access mode needs to be activated according to the request message and the transmission requirement of the service.

After the UE adjusts the sub-flow of the first access mode to the idle state, the specific manner of determining that the sub-flow of the first access mode needs to be used at least includes the foregoing three types: detecting the current sub-flow of the second access mode The sub-flow of the first access mode may be directly activated by the request message sent by the server, or the request message sent by the server may be combined with the transmission requirement of the service to determine whether the first access needs to be activated. The sub-flow of the mode can be set according to the actual situation in the specific implementation.

A second aspect of the present invention provides a service flow routing method, which is applied to a server, and the method includes:

The server transmits the service data of the UE to the UE by using the first access mode and the second access mode;

The server receives the first indication message sent by the UE, where the first indication message is used to indicate that the UE has adjusted the sub-flow of the first access mode to an idle state;

The server transmits data to the UE through the sub-flow of the second access mode.

The solution is a server-side solution corresponding to the UE side provided by the first aspect, and the server simultaneously uses the sub-flow of the first access mode and the sub-flow of the second access mode to perform data transmission with the UE, and the UE detects the The sub-flow of the second access mode can meet the transmission requirement of the service, and the sub-flow of the first access mode is adjusted to the idle state, and the server receives the first indication message sent by the UE, and uses only the second access mode according to the indication message. The sub-flow transmits data to the UE, so that the network-side device corresponding to the first access mode releases the resource, and the specific access mode is adjusted to the idle mode without closing the sub-flow, and the first access mode is saved at the same time. resource of.

Optionally, the first access mode is 3GPP access.

Optionally, the method further includes:

The server receives the second indication message sent by the UE, where the second indication message indicates that the server can transmit data to the UE by using the sub-flow of the first access mode;

The server transmits data to the UE through the sub-flow of the first access mode and the sub-flow of the second access mode.

Optionally, the server receives the second indication message sent by the UE, including:

Receiving, by the server, a second indication message sent by the UE by using the sub-flow of the first access mode;

or,

The server receives a second indication message that is sent by the UE by using the sub-flow of the second access mode.

Optionally, the server receives the first indication message sent by the UE, including:

Receiving, by the server, the first indication message sent by the UE by using the sub-flow of the first access mode;

or,

The server receives the first indication message that is sent by the UE by using the sub-flow of the second access mode.

Optionally, before the server receives the second indication message sent by the UE, the method further includes:

The server determines, according to the transmission requirement of the service of the UE, whether the sub-flow of the first access mode needs to be used for data transmission to the UE;

If the server determines that the sub-flow of the first access mode needs to be used for data transmission to the UE, sending a request message to the UE; the request message is used to request to use the sub-stream of the first access mode to transmit data.

In the above solution, the first access mode is the 3GPP access mode, and the second access mode is the WIFI access mode. The transmission requirement of the service generally refers to the service quality of service (English: Quality of Service, referred to as : QoS) requirements, including: bandwidth requirements and quality of service priority requirements. The UE detects that the WIFI connection can meet the transmission requirement of all services according to the transmission requirement, and the UE sends a “sub-flow status update indication” message, that is, the first indication message, to the communication server, and the message carries the sub-flow status update indication, indicating that the The sub-flow state of the 3GPP access mode is adjusted to the idle state, and the base station does not detect the packet for a long time, and the base station initiates the release of the 3GPP-side air interface resource. Adjusting the sub-flow of the first access mode to the idle mode without turning off the sub-flow while saving the cellular network air interface resources. When the UE detects that the traffic on a certain sub-flow of the WIFI access mode exceeds the transmission capability of the WIFI connection, the UE exits the idle state of the 3GPP side, and the base station and the network reestablish the 3GPP side air interface resource. The UE sends a sub-flow status update indication message, that is, a second indication message, to the server that communicates with the sub-flow of the WIFI access mode or the sub-flow of the 3GPP access mode, where the second indication message carries the sub-flow status update indication. The server is instructed to send data through the sub-stream of the 3GPP access mode, to avoid the need to initiate the establishment of the corresponding sub-flow when the access mode needs to be reused, and reduce the number of processing signaling by the UE and the server, and implement process optimization.

A third aspect of the present invention provides a service flow routing method, where the method includes:

Receiving, by the UE, a paging message sent by the base station;

The UE exits the idle state according to the paging message, and receives data transmitted by the server through the substream of the first access mode and the substream of the second access mode;

The UE supports the transmission of service data by using the first access mode and the second access mode.

Optionally, the first access mode is 3GPP access.

In the above solution, the UE detects that the sub-flow of the second access mode can meet all the service transmission requirements, and when the UE adjusts the sub-flow of the first access mode to the idle state, the UE sends the sub-flow to all the servers. The status update indication, that is, the first indication message, indicates that the UE has adjusted the sub-flow of the first access mode to the idle state, and the server only uses the sub-stream of the second access mode to transmit the service data. When the server detects that the data needs to be transmitted through the sub-stream of the first access mode, the data is directly sent through the sub-flow of the first access mode in the idle state, and the network device is triggered, for example, the base station searches for the UE. Call and exit the idle state of the first access mode. This prevents the server from sending a request to the UE that communicates with it, and can directly send data on the sub-stream of the first access mode in the idle state.

Optionally, the first indication message further includes an activation condition of the substream of the first access mode.

Based on the foregoing solution, the first indication message carries a substream activation condition. When the server side determines that the activation condition is met, the server directly sends data through the idle state sub-flow, triggering the network device to page the UE and exit the idle state of the sub-flow of the first access mode, thereby avoiding an increase in the number of signaling.

A fourth aspect of the present invention provides a service flow routing method, where the method includes:

The server transmits the service data of the UE to the UE by using the second access mode;

Determining, by the server, whether the transmission requirement of the service of the UE satisfies an activation condition of the sub-flow of the first access mode of the UE acquired in advance;

If it is determined that the transmission requirement of the service of the UE meets the activation condition of the sub-flow of the first access mode of the UE, the server transmits data to the UE by using the sub-flow of the first access mode and the sub-flow of the second access mode.

Optionally, before the server transmits the service data of the UE by using the second access mode, the method further includes:

The server transmits the service data of the UE by using the first access mode and the second access mode;

In this solution, the server uses the first access mode and the second access mode sub-flow to transmit to the UE. After the UE sends the first indication message to indicate that the first access mode is adjusted to the idle state, the server may The transmission requirement of the service determines whether the activation condition of the sub-flow of the first access mode is met. If yes, the server directly sends data on the sub-flow of the first access mode, triggering the paging of the network device to the UE, thereby triggering the UE The first access mode is activated to avoid an increase in the number of signaling.

In the above solution, the control plane network element (which may be a mobility management entity, etc.) pre-delivers a policy to the forwarding plane network element, and the forwarding plane network element detects the traffic of each sub-flow, and reports the traffic to the control plane when the traffic exceeds a certain threshold. The network element, the control plane network element sends a "sub-flow status update command" message to the forwarding plane network element according to the sub-flow traffic condition on each access technology path, that is, the first state update command, indicating that the first access mode is to be performed.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled 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 schematic diagram of a network architecture of a service flow routing method according to the present invention. As shown in FIG. 1, the service flow routing method is mainly applied to communication of a user terminal supporting MPTCP in an EPC network architecture. The network element involved in the processing method includes a user terminal supporting MPTCP, a server providing services for the user terminal (the server may be a proxy server), a control plane network element, and a forwarding plane network element. The control plane network element is responsible for user and session management. For example, the control plane network element may include a mobility management entity (English: Mobility Management Entity, MME for short), a mobile network controller, and the like. The forwarding plane NE is used to complete the forwarding, statistics, and other processing functions of user packets. For example, the forwarding plane network element may include a packet data gateway (English: Packet Data Network Gateway, PDN-GW for short), a service gateway (English: Serving GateWay, S-GW for short), a GW forwarding plane, and a software-defined network converter. (English: Software Defined Network switch, referred to as: SDN switch). The technical solution provided by the present application can also be applied to state control of other multi-path transmission protocols, and It is limited to the MPTCP protocol.

Based on the foregoing network architecture, the present application provides a service flow routing method in a multi-connection scenario. The UE instructs the server to perform a routing policy according to the access technology, so as to ensure that the specific access side can be closed without shutting down the sub-flow. Normally enter idle mode to avoid waste of resources. The service flow routing method provided by the present application is described in detail below through several embodiments.

FIG. 2 is a flowchart of Embodiment 1 of a service flow routing method according to the present invention. As shown in FIG. 2, the UE supports the MPTCP technology, and the UE supports communication between multiple substreams through at least two access modes and the server. The UE can communicate with multiple servers. In the following embodiment, a server is used as an example. The specific implementation steps of the service flow routing method are as follows:

S101: The server transmits the service data of the UE by using the first access mode and the second access mode.

In this step, the UE and the server simultaneously use the multiple access modes of the first access mode and the second access mode to perform service data transmission. For example, business data includes upstream or downstream data. The first access mode and the second access mode may be access modes of two different attributes in the access mode, such as WIFI access and 3GPP access, for example, the first access mode is 3GPP access, and the first access mode is The second access mode is WIFI access, or the first access mode is WIFI access, and the second access mode is free WIFI access; or the first access mode is 4G access, and the second access mode is 4G access. The entry mode is 5G access.

S102: If the UE detects that the sub-flow of the second access mode can meet the transmission requirement of the service, the UE adjusts the sub-flow of the first access mode to an idle state, and sends a first indication message to the server.

For example, the transmission requirements of the service include the quality of service (English: Quality of Service, QoS for short). QoS requirements include, but are not limited to, one or more of bandwidth requirements and quality of service priority requirements. If the UE detects that the sub-flow of the second access mode can meet the transmission requirement of the service of the UE, the UE adjusts the sub-flow of the first access mode to an idle state, and the UE does not use the first access mode. The substream transfers data and releases resources.

After adjusting the sub-flow of the first access mode to the idle state, the UE sends a first indication message to the server that communicates with the server. The first indication message is also referred to as a “sub-flow status update indication message”, and the first indication message carries a sub-flow status update indication. The first indication message is used to indicate that the UE has adjusted the sub-flow of the first access mode to an idle state.

Before receiving the first indication message, the server transmits the service data of the sub-flow of the first access mode and the sub-flow of the second access mode to the UE. The UE sends the first indication message. After receiving the first indication message, the server obtains that the sub-flow of the first access mode has been adjusted to the idle state, and the server stops using the sub-flow of the first access mode for data transmission.

S103: The UE receives data that is transmitted by the server through the substream of the second access mode.

In this step, the server stops using the sub-flow of the first access mode to send service data to the UE according to the first indication message, and only transmits data to the UE by using the sub-flow of the second access mode.

For the UE, the UE receives data sent by the server through the second access mode. During the whole process, the UE does not need to shut down the sub-flow of the first access mode, and only needs to release the first access mode resource, and notify the server to adjust the sub-flow of the first access mode by using the first indication message. Is idle.

In the foregoing process, the UE may send the first indication message to the server, where the first indication message may be sent to the server by using the sub-flow of the first access mode, or may be sent to the server by using the sub-flow of the second access mode. There are no restrictions on this program.

In the service flow routing method provided by the embodiment, the UE sends a first indication message to the server to notify the UE of the sub-flow status update indication of the access mode, and the notification server uses the sub-flow of the access mode to send the service data, that is, the indication server. The routing policy is executed to ensure that the sub-flow of a specific access mode can enter the idle mode without shutting down the sub-flow, thereby avoiding waste of resources.

FIG. 3 is a flowchart of Embodiment 2 of a service flow routing method according to the present invention. As shown in FIG. 3, after the server uses the sub-flow of the second access mode to transmit service data to the UE, the UE may further The server re-uses the sub-flow of the first access mode to perform data transmission according to the service requirement. The specific implementation steps are as follows:

S201: If the UE determines that the sub-flow of the first access mode needs to be used, the UE exits the idle state.

In this step, the UE needs to determine whether to re-enable the sub-flow of the first access mode, and the specific determining manner includes at least the following:

In the first method, if the UE detects that the sub-flow of the second access mode cannot meet the transmission requirement of the service, it is determined that the sub-flow of the first access mode needs to be used.

The meaning of the solution is that the UE detects that the traffic on a certain sub-flow of the second access mode exceeds the transmission capability of the second access mode, and determines that the first access mode needs to be used.

In a second determining manner, the UE receives a request message sent by the server, where the request message is used to request to use the sub-stream of the first access mode to transmit data, and after receiving the request message, the UE determines that The substream of the first access method is to be used.

The meaning of the solution is that after determining that the service transmission requirement of the UE meets the activation condition of the first access mode, the server initiates a request to the UE to request to use the first access mode for data transmission, and the UE determines that the first needs to be used according to the request message. Access method.

In a third determining manner, the UE receives the request message sent by the server; the request message is used to request to use the sub-stream of the first access mode to transmit data; and the UE determines, according to the request message and the transmission requirement of the service, whether the first access mode needs to be activated. Subflow.

The meaning of the solution is: after receiving the request message sent by the server for requesting the use of the sub-stream transmission data of the first access mode, the UE needs to detect the transmission status of the sub-flow of the second access mode, and the transmission requirement of the service. Determine whether the sub-flow of the first access method is needed.

In the above manner, the UE determines that the sub-flow of the first access mode is to be used, and then controls the first access mode to exit the idle mode, that is, activates the sub-flow of the first access mode. The specific implementation manner is as follows: The UE initiates a server request and reestablishes an air interface bearer.

S202: The UE sends a second indication message to the server.

In this step, after the UE determines that the sub-flow of the first access mode needs to be used, the sub-flow of the first access mode is activated, and the second indication message is sent to the server. The second indication message is used to indicate that the server can transmit data to the UE by using the sub-flow of the first access mode. That is, the UE activates the first access mode and notifies the server.

When the UE sends the second indication message to the server, the second indication message may be sent to the server by using the sub-flow of the first access mode. The second indication message may also be sent to the server by the sub-flow of the second access mode.

S203: The UE receives data that is transmitted by the server by using the sub-flow of the first access mode and the sub-stream of the second access mode.

In this step, the server receives the second indication message sent by the UE, and according to the second indication message, the service data is transmitted to the UE by using the sub-flow of the first access mode and the sub-flow of the second access mode.

In the service flow routing method provided in this embodiment, when the UE determines that the sub-flow of the first access mode is to be used, the UE exits the idle state of the first access mode, and sends a second indication message to all servers that communicate with the UE. The second indication message carries a sub-flow status update indication, indicating that the server can send data by using the sub-flow of the first access mode. When the first access mode needs to be re-used, the establishment of the corresponding sub-flow needs to be initiated, which reduces the number of signaling processed by the UE and the server, and implements the process optimization. Chemical.

With reference to the foregoing first embodiment and the second embodiment, the following describes the service routing method by using the first access mode as the 3GPP access and the second access mode as the WIFI access as an example. In the subsequent figures, the base station (English: base station, abbreviated as BS).

FIG. 4 is an interaction flowchart of a specific implementation manner of a service flow routing method according to an embodiment of the present invention. As shown in FIG. 4, the UE dynamically adjusts the state of the substream of the 3GPP access mode according to the QoS requirement, and the specific implementation steps are as follows:

S301: The UE detects that the WIFI access mode can meet the transmission requirements of all services.

Before this step, the server and the UE simultaneously transmit data through the sub-flow of the WIFI access mode and the sub-stream accessed by the 3GPP.

In this step, the transmission requirement of the service refers to the QoS requirement, and the QoS specifically includes: a scale value indicating a delay and a packet loss rate (English: QoS Class Identifier, QIC for short), an allocation reservation priority, and a bandwidth.

S302: The UE sends the first indication message to the server by using the sub-flow of the 3GPP access mode.

In the above steps, the UE detects that the sub-flow of the WIFI access mode can meet the transmission requirement of all services, and the UE sends a “sub-flow status update indication” message to all servers (Servers) of the sub-flow of the 3GPP access mode with which it communicates. , that is, the first indication message is sent. The first indication message carries a sub-flow status update indication, which is used to indicate that the sub-flow status of the 3GPP access mode is adjusted to an idle state. For example, the subflow status update indication can be identified by defining an MPTCP Option MP_ACTIVE=1.

Optionally, after the UE sends the first indication message to the server by using the sub-flow of the 3GPP access mode, the UE sends a TCP keepalive message to the server of the 3GPP access mode sub-flow that communicates with the UE. If the UE does not receive a response from the server after the preset time, the UE determines that the server is no longer transmitting data on the substream of the 3GPP access mode that communicates with the UE.

S303: The base station does not detect the packet within a preset time.

S304: The base station initiates air interface resource release.

In the above step, the base station does not detect the packet for a long time, and the base station initiates the release of the 3GPP side air interface resource.

S305: The server transmits the service data to the UE by using the sub-flow of the WIFI access mode.

After receiving the first indication message, the server does not pass through the substream of the 3GPP access mode. For the transmission of the service data, the service data is transmitted to the UE only through the sub-flow of the WIFI access mode.

In this solution, steps S302 to S305 are specific implementation manners for adjusting the 3GPP access mode to the idle state.

S306: The UE detects that the traffic on a certain sub-flow of the WIFI access mode exceeds the transmission capability of the WIFI connection.

S307: The UE exits the idle state, and the base station and the network re-establish the air interface resource.

In the above step, when the UE detects that the traffic on a certain sub-flow of the WIFI access mode exceeds the transmission capability of the WIFI connection, for example, the packet loss rate during the data transmission exceeds the maximum allowed by the WIFI access mode. At the packet rate, the UE initiates the base station and the network to re-establish the 3GPP side air interface resource, and implements the 3GPP idle state.

S308: The UE sends a second indication message to the server by using the 3GPP sub-flow.

In this step, the UE sends a "sub-flow status update indication" message, that is, a second indication message, to all servers of the sub-flow of the 3GPP access mode with which it communicates. The second indication message carries a sub-flow status update indication, which is used to indicate that the server can send data through the sub-stream of the 3GPP access mode. For example, the substream status update indication can be identified by defining an MPTCP Option MP_ACTIVE=0.

S309: The server transmits the service data to the UE by using the sub-flow of the WIFI access mode and the sub-flow of the 3GPP access mode.

In this step, after receiving the second indication message, the server re-uses the sub-flow of the 3GPP access mode to perform service data transmission, and the UE and the server simultaneously use multiple sub-flows of multiple access modes to communicate.

In this solution, the UE dynamically sends the sub-flow status update indication message to the server of the sub-flow of the 3GPP access mode that communicates with the UE according to the transmission requirement of the service, and dynamically adjusts the state of the sub-flow of the 3GPP access mode, and is also applicable to communicating with the UE. Any one of the servers may send a "sub-flow status update indication" message to the servers according to the transmission requirement of the service to dynamically adjust the status of the sub-flow of the 3GPP access mode.

Compared with the prior art, the scheme only uses the "sub-flow status update indication" message to adjust the state of the access technology sub-flow, so that the specific access side can normally enter the idle mode without shutting down the sub-flow, thereby avoiding Waste of cellular network air interface resources.

The service flow routing method provided by the implementation manner is detected by the UE according to the transmission requirement of the service. The WIFI access mode can meet the transmission requirements of all services, and the UE sends a first indication message to the server of the sub-flow of the 3GPP access mode that communicates with the UE, and the message carries the sub-flow status update indication, indicating that the 3GPP access mode is used. The flow state is adjusted to the idle state. The base station does not detect the packet at the preset time, and the base station initiates the release of the 3GPP side air interface resource. The access technology is adjusted to the idle mode without turning off the substream while saving the cellular network air interface resources. When the UE detects that the traffic on a certain sub-flow of the WIFI access mode exceeds the transmission capability of the WIFI access mode, the UE exits the idle state of the 3GPP side, and the base station and the network reestablish the 3GPP side air interface resource. The UE sends a second indication message to the server of the sub-flow of the 3GPP access mode, and the message carries the sub-flow status update indication, indicating that the server can send data through the sub-flow of the 3GPP access mode. To avoid the need to re-use the access technology, it is necessary to initiate the establishment of the corresponding sub-flow, which reduces the number of signaling processed by the UE and the server, and implements process optimization.

FIG. 5 is a flowchart of another specific implementation manner of the service flow routing method according to the embodiment of the present invention. As shown in FIG. 5, the UE dynamically adjusts the state of the sub-flow of the 3GPP access mode according to the bandwidth requirement and the service QoS priority requirement. In the specific steps of the provided service flow routing method, steps S401, S403 to S407, and S409 are implemented in the same manner as S301, S303 to S309 in FIG. 4 described above. Steps S402 and S408 are different from S302 described above. specific,

S402: The UE sends the first indication message to the server by using the sub-flow of the WIFI access mode.

In the above steps, the UE detects that the sub-flow of the WIFI access mode can meet the transmission requirement of all services, and the UE sends a “sub-flow status update indication” message to the server of the sub-flow of the WIFI access mode with which the UE communicates, that is, the first Indicate the message. The first indication message carries a sub-flow status update indication, which is used to indicate that the sub-flow status of the 3GPP access mode is adjusted to an idle state. For example, the sub-flow status update indication may be identified by defining an MPTCP Option MP_ACTIVE=1.

Optionally, after the UE sends the first indication message to the server by using the sub-flow of the WIFI access mode, the UE sends a TCP keepalive message to the server of the 3GPP access mode sub-flow that communicates with the UE, if the preset time is If no response is received from the server, it is determined that the server is no longer transmitting data on the substream of the 3GPP access mode that communicates with the UE.

S408: The UE sends a second indication message to the server by using the WIFI sub-flow.

In this step, the UE sends a second indication message carrying a sub-flow status update indication to the server with which it communicates. The second indication message indicates that the server can send data through the substream of the 3GPP connection. For example: subflow status update indication can be defined by defining an MPTCP Option MP_ACTIVE=0 To identify.

Compared with the prior art, the sub-flow is sent by the sub-flow of the WIFI access mode to dynamically adjust the state of the sub-flow of the 3GPP access mode, so as to ensure the specificity without shutting down the sub-flow. The access side can enter the idle mode normally to avoid waste of cellular network air interface resources.

The service flow routing method provided by the implementation manner, the UE detects that the WIFI access can meet the transmission requirement of all services according to the transmission requirement of the service, and the UE sends the first indication message to the server of the sub-flow of the WIFI access mode with which the UE communicates, the message The sub-flow status update indication is carried in, indicating that the sub-flow status of the 3GPP access mode is adjusted to an idle state. The base station does not detect the packet for a long time, and the base station initiates the release of the 3GPP side air interface resource, so that the access technology is adjusted to the idle mode without turning off the substream, and the cellular network air interface resource is saved. When the UE detects that the traffic on a certain sub-flow of the WIFI access mode exceeds the transmission capability of the WIFI access mode, the UE exits the idle state of the 3GPP side, and the base station and the network reestablish the 3GPP side air interface resource. The UE sends a second indication message to the server of the sub-flow of the WIFI access mode, which carries the sub-flow status update indication, indicating that the server can send data through the sub-flow of the 3GPP access mode, and the need to re-use the access is avoided. The technology needs to initiate the establishment of the corresponding sub-flow, which reduces the number of processing signaling by the UE and the server, and implements process optimization.

FIG. 6 is an interaction flowchart of still another specific implementation manner of a service flow routing method according to an embodiment of the present invention. As shown in FIG. 6 , in the specific implementation steps of the service flow routing method, steps S501 to S505 are in the foregoing FIG. 4 . S301 to S305 are implemented in the same manner, S510 and S511 are the same as S308 and S309 in FIG. 4, and steps S506 to S509 are different from the foregoing scheme. specific,

S506: The server determines, according to the transmission requirement of the service of the UE, whether the sub-flow of the 3GPP access mode needs to be used for data transmission to the UE.

S507: The server sends a request message to the UE by using a sub-flow of the WIFI access mode.

In this step, the server according to the transmission requirement of the service of the UE, for example, the sub-flow of the current access mode cannot provide sufficient bandwidth or transmission QoS, and determines that the sub-flow of the 3GPP access mode needs to be used for data transmission, and the server (Server) sends a "sub-flow status update request" message to the UE that communicates with the UE through the WIFI access mode, that is, the sub-flow in the WIFI access mode sends a request message to the UE. The request message is used to request data transmission using a substream of the 3GPP access method.

S508: The UE determines, according to the request message and the transmission requirement of the service, whether the sub-flow of the 3GPP access mode needs to be activated.

S509: The UE exits the idle state, and the base station and the network re-establish the air interface resource.

In the above step, after receiving the "sub-flow status update request" message sent by the server, that is, the above-mentioned request message, the UE determines whether it is necessary to adjust the sub-flow of the 3GPP access mode to the ACTIVE state according to the transmission requirement of the service, that is, exit. Idle state. If necessary, the substream of the 3GPP access mode is adjusted to the ACTIVE state. The UE exits the idle state of the 3GPP side, and the base station and the network reestablish the 3GPP side air interface resource.

In this solution, the server can determine whether the sub-flow of the 3GPP access mode needs to be adjusted to the ACTIVE state according to the transmission requirement of the UE, so that the server can dynamically adjust the state of the sub-flow of the 3GPP access mode.

In addition, when the UE sends the first indication message to the server, it may be sent by the sub-stream of the 3GPP access mode or by the sub-flow of the WIFI access mode, and the implementation manners shown in FIG. 4 and FIG. 5 are specifically implemented.

In the service flow routing method provided by the implementation manner, after the UE sends the first indication message to indicate that the sub-flow of the 3GPP access mode is adjusted to the idle state, the server uses only the sub-flow of the WIFI access mode to transmit the service data to the UE. When the server determines the sub-flow that needs to use the 3GPP access mode according to the transmission requirement of the service, the UE sends a request message to the UE that communicates with the UE through the WIFI access mode, and the UE determines whether the sub-flow of the 3GPP access mode needs to be activated. If necessary, the UE adjusts the sub-flow of the 3GPP access mode to the ACTIVE state, exits the idle state of the 3GPP side, and the base station and the network reestablish the 3GPP side air interface resource. To avoid the need to re-use the access technology, it is necessary to initiate the establishment of the corresponding sub-flow, which reduces the number of signaling processed by the UE and the server, and implements process optimization.

FIG. 7 is a flowchart of Embodiment 3 of a service flow routing method according to the present invention. As shown in FIG. 7, the implementation steps of the service flow routing method provided in this embodiment are as follows:

S601: If the UE detects that the sub-flow of the second access mode can meet the transmission requirement of the service, the UE sends a first indication message to the server.

Before the step, the server transmits the service data of the UE by using the first access mode and the second access mode. For example, the service data of the UE includes uplink data or downlink data of the UE. The uplink data or downlink data of the UE can be transmitted by using sub-streams of two access methods.

In this step, if the UE detects that the sub-flow of the second access mode can meet the transmission requirements of all services, it is determined that the first access mode is not needed. At this time, the UE may adjust the first access mode to the idle state, and send a first indication message to the server, where the first indication message is used to refer to The server indicates that the UE has adjusted the sub-flow of the first access mode to an idle state, that is, the server is notified not to use the sub-stream of the first access mode to send data.

After receiving the first indication message, the server transmits the service data to the UE only through the sub-flow of the second access mode.

S602: The server determines whether the transmission requirement of the service of the UE satisfies an activation condition of the sub-flow of the first access mode of the UE.

In this step, the server needs to obtain the activation condition of the sub-flow of the first access mode of the UE in advance. For example, the obtaining manner may be configured on the server side in advance; or the first indication message sent by the UE may be used to carry the activation condition of the sub-flow, that is, the first indication message received by the server indicates the sub-flow indicating the first access mode. It is adjusted to the idle state, and further includes an activation condition of the substream of the first access mode.

The server determines whether the transmission requirement of the UE service meets the activation condition of the sub-flow of the first access mode of the UE, and if it is determined that the transmission is not satisfied, the server continues to use the sub-stream of the second access mode to transmit the data of the UE, if it is determined If the content is satisfied, the server can directly send data to the UE through the sub-flow of the first access mode.

S603: If yes, the server transmits data to the UE by using the sub-flow of the first access mode and the sub-flow of the second access mode.

In this step, the server determines the activation condition of the sub-flow that satisfies the first access mode, and the server directly sends the data to the UE through the sub-flow of the first access mode in the idle state, and may only use the first access mode. The sub-stream is sent, and the data may be transmitted to the UE through the sub-flows of the first access mode and the second access mode at the same time.

S604: The UE receives the paging message sent by the network side device.

In this step, the data sent by the server triggers paging of the UE by the network side. If it is in the 3GPP access mode, the network side device is a base station, the base station pages the UE, and the UE exits the idle state.

S605: The UE exits the idle state according to the paging message, and receives data that is transmitted by the server through the substream of the first access mode and the substream of the second access mode.

In this step, the UE exits the idle state according to the paging message, and directly receives the service data sent by the server through the first access mode or the sub-streams of the first access mode and the second access mode.

That is, multiple substreams of multiple access modes are simultaneously used for communication between the UE and the server.

The service flow routing method provided by this embodiment, the UE sends the first to all servers communicating with the UE An indication message carries a sub-flow activation condition. When the server side determines that the activation condition is met, the server directly sends data through the idle state sub-flow, triggering the network to initiate paging to the UE and exit the first access by using the first access mode. The idle state of the mode side uses multiple sub-flows of multiple access modes to transmit service data, thereby avoiding an increase in the number of signaling.

With reference to the technical solution of the foregoing embodiment 3, the following is an example in which the first access mode is 3GPP access and the second access mode WIFI access is used as an example.

FIG. 8 is an interaction flowchart of still another specific implementation manner of a service flow routing method according to an embodiment of the present invention. As shown in FIG. 8 , in the implementation steps of the routing method of the service flow, S701, S703 to S705, and FIG. 4 S301, S303 to S305 are the same, and other steps are different from the foregoing embodiment, specifically,

S702: The UE sends a first indication message to the server.

In the above steps, different from S302, the first indication message carries a sub-flow activation condition (such as a bandwidth requirement threshold, a QoS requirement, and the like) and a sub-flow status update indication. Similarly, the sub-flow status update indication is used to indicate that the UE has adjusted the sub-flow status of the 3GPP connection to an idle state. For example, the substream status update indication can be identified by defining an MPTCP Option MP_ACTIVE=1.

S706: The server determines whether the transmission requirement of the service of the UE satisfies an activation condition of the substream of the 3GPP access mode.

S707: The server sends the service data to the UE by using the sub-flow of the 3GPP access mode in the idle state, and triggers the paging of the UE by the base station, so that the UE exits the idle state.

In the above step, the server side determines whether the transmission requirement of the service of the UE satisfies the activation condition of the substream of the 3GPP access mode. For example, the bandwidth threshold is 3M. When the service traffic exceeds 3M, the server determines the activation condition of the sub-flow that satisfies the 3GPP access mode, and the server can directly send data through the sub-stream of the 3GPP access mode in the idle state, triggering the base station to pass the 3GPP. The technology initiates paging to the UE to cause the UE to exit the idle state on the 3GPP side.

S708: The server transmits the service data to the UE by using the sub-flow of the WIFI access mode and the sub-flow of the 3GPP access mode.

In this step, after re-activating the substream of the 3GPP access mode, the UE and the server simultaneously use multiple substreams of multiple access modes to communicate.

In the service flow routing method provided by the implementation manner, the UE adjusts the substream of the 3GPP connection to be empty. In the idle state, the UE sends a sub-flow activation condition (such as QoS requirements, etc.) to the first indication message sent by the server with which it communicates. When the server determines that the activation condition is satisfied, the server directly sends data through the sub-stream of the 3GPP access mode in the idle state, triggering the paging of the UE to the UE, so that the UE exits the idle state of the 3GPP side. In this way, the server is prevented from sending a request to the UE that communicates with the UE. The server directly sends data through the idle state sub-flow, triggering the network to trigger the paging of the base station to the UE through the 3GPP access mode, and avoiding an increase in the number of signaling.

FIG. 9 is a flowchart of Embodiment 4 of a service flow routing method according to the present invention. As shown in FIG. 9, in this embodiment, a control plane network element is used as an intermediate control device, and a sub-flow status update command message is sent to the forwarding network. The element is used to dynamically adjust the state of the substream of the first access mode. The specific implementation steps are as follows:

S801: The control plane network element receives the first status indication message sent by the forwarding plane network element of the second access mode.

Before the step, the server and the UE perform data transmission only through the sub-flow of the second access mode, and the sub-flow of the first access mode is in an idle state. The UE supports transmission of service data by using the first access mode and the second access mode.

The first status indication message indicates that the traffic on the sub-flow of the second access mode of the UE exceeds a preset threshold, that is, the forwarding plane network element of the second access mode detects that the sub-flow of the second access mode cannot satisfy the service of the UE. The transmission status is reported to the control plane network element.

S802: The control plane network element sends a first state update command to the forwarding plane network element of the first access mode.

In this step, the control plane network element determines that the substream of the first access mode needs to be activated according to the received first state indication message. The control plane network element sends a first state update command to the forwarding plane network element of the first access mode, which is used to indicate that the substream of the first access mode of the UE is activated.

S803: The forwarding plane network element of the first access mode activates the substream of the first access mode of the UE according to the first state update command.

In this step, the forwarding plane network element sends an indication to the control plane network element, and the control plane network element triggers the network side device to page the UE, so that the UE exits the idle state and performs resource reconstruction.

S804: The forwarding plane network element of the first access mode sends a second indication message to the UE and the server respectively.

In this step, the second indication message is used to indicate that the service data can be transmitted between the UE and the server through the sub-flow of the first access mode. That is, the forwarding plane network element of the first access mode separately informs the UE and the service. The server can use the substream of the first access method.

S805: The server transmits data to the UE by using the sub-flow of the first access mode and the sub-flow of the second access mode.

In this step, data communication can be performed between the server and the UE through multiple substreams of the first access mode and the second access mode. The data communication here includes uplink data communication and downlink data communication. For example, the UE receives data transmitted by the server through the sub-stream of the first access mode and the sub-stream of the second access mode.

Before the step S801 or after S805, the control plane network element may further control the sub-flow of the first access mode or the second access mode to be in an idle state according to the detection of the traffic of each forwarding plane network element. For example, the first access mode is adjusted to the idle state.

On the control plane network element side, the control plane network element obtains the traffic information of the sub-flow of the first access mode of the UE and the traffic information of the sub-flow of the second access mode.

The specific way to obtain the traffic information of each substream is as follows:

The control plane network element receives the second status indication message sent by the forwarding plane network element of the first access mode, and the second status indication message carries the traffic information of the sub-flow of the first access mode of the UE.

The control plane network element receives the third status indication message sent by the forwarding plane network element of the second access mode, and the third status indication message carries the traffic information of the sub-flow of the second access mode of the UE.

After the control plane network element obtains the traffic information of the sub-flow of the first access mode and the traffic information of the sub-flow of the second access mode, the control plane network element needs to transmit according to the service of the UE, and the first access mode The traffic information of the sub-flow and the traffic information of the sub-flow of the second access mode determine whether the sub-flow of the second access mode satisfies the transmission requirement of the service of the UE. If the control plane network element determines that the sub-flow of the second access mode meets the service requirement of the UE, sends a second state update command to the forwarding plane network element of the first access mode, where the second state update command is used Instructing to adjust the sub-flow of the first access mode of the UE to an idle state.

On the forwarding side network element side of the first access mode, the forwarding plane network element of the first access mode sends a second status indication message to the control plane network element; the second status indication message carries the UE of the first access mode of the UE. Flow information of the flow, so that the control plane network element determines, according to the traffic information, whether the first access mode is to be adjusted to an idle state.

If the forwarding plane network element of the first access mode receives the second state update command sent by the control plane network element, the forwarding plane network element of the first access mode performs the first connection of the UE according to the second state update command. The subflow of the incoming mode is adjusted to the idle state;

Further, the forwarding plane network element of the first access mode sends a first indication message to the UE and the server, where the first indication message is used to indicate that the sub-flow of the first access mode of the UE is adjusted to an idle state. That is, the forwarding plane network element of the first access mode needs to separately notify the server and the UE that the sub-flow of the first access mode of the UE has been adjusted to an idle state, so that the UE and the server no longer use the first access mode. The substream carries the data for transmission.

On the server side, the server receives the first indication message sent by the forwarding plane network element of the first access mode, where the first indication message is used to indicate that the sub-flow of the first access mode of the UE is adjusted to an idle state, and the first indication is received. After the message is indicated, the server performs data transmission with the UE only through the sub-flow of the second access mode.

On the UE side: the UE receives the first indication message sent by the forwarding plane network element of the first access mode, where the first indication message indicates that the sub-flow of the first access mode is adjusted to an idle state, and after receiving the first indication message, the UE receives the first indication message. The UE performs data transmission between the sub-flow of the second access mode and the server.

In the service flow routing method provided by the embodiment, when the forwarding plane network element detects that the traffic of the sub-flows of each access mode exceeds a certain threshold, the forwarding plane network element sends a sub-flow status indication message to the control plane network element. The control plane network element integrates the traffic of the sub-flows on the path of each access mode, and sends a status update command message to the network element of the forwarding plane, indicating that the sub-flow of the first access mode is adjusted to the idle state, or is activated, and is activated through the middle. The control of the network element adjusts the state of the access technology path to achieve the effect of signaling reduction and route optimization.

On the basis of the foregoing embodiment 4, the following is an example in which the first access mode is the 3GPP access and the second access mode is the WIFI access.

FIG. 10 is an interaction flowchart of still another specific implementation manner of a service flow routing method according to an embodiment of the present invention. As shown in FIG. 10, the specific implementation steps of the service flow routing method are as follows:

S901: The forwarding plane network element 1 detects the traffic of a certain substream of the 3GPP access mode.

Before this step, the sub-flow of the 3GPP access mode and the sub-flow of the WIFI access mode are used for the service data transmission between the server and the UE, that is, the uplink or downlink data of the UE is transmitted through the sub-flow 1 and the sub-stream 2 in the figure. The forwarding plane network element 1 needs to perform real-time detection on the traffic of each substream connected to the 3GPP.

S902: The forwarding plane network element 1 reports the second status indication message to the control plane network element.

In this step, the forwarding plane network element 1 detects that the traffic of a certain substream of the 3GPP access mode exceeds When a certain threshold is used, the forwarding plane network element 1 reports the traffic flow of the sub-flow to the control plane network element, and the forwarding plane network element 1 sends a second status indication message to the control plane network element, where the second status indication message carries the sub-stream traffic. Status indication.

S903: The forwarding plane network element 2 reports the third status indication message to the control plane network element.

In this step, the forwarding plane network element 2 can actively report the third status indication message carrying the sub-flow information. After the control plane network element sends the sub-flow status request to the forwarding plane network element, the forwarding plane network element further reports the third status indication message according to the request.

The control plane network element sends a "sub-stream traffic status request" message to the forwarding plane network element 2, and requests the forwarding plane network element 2 to report the traffic condition of the sub-flow of the WIFI access mode to the control plane network element. The forwarding plane network element 2 sends a "sub-stream traffic status indication" message to the control plane network element, that is, reports the third status indication message carrying the traffic information to the control plane network element, and reports the traffic status of the sub-flow of the WIFI access mode. Face network element.

S904: The control plane network element integrates the sub-flow traffic information of each access mode, and determines whether the sub-flow of the WIFI access mode satisfies the transmission requirement of the service of the UE.

S905: The control plane network element determines that the sub-flow of the WIFI access mode meets the service requirement of the UE, and sends a second status update command to the forwarding plane network element 1.

In the above steps, the control plane network element integrates the sub-flow traffic information on each access technology path to determine whether the sub-flow of the WIFI access mode can meet the service requirement of the UE, that is, determine whether to adjust the sub-flow of the 3GPP access mode. Is idle. If it is determined that the sub-flow of the WIFI access mode can meet the transmission requirement, the control plane network element sends a second status update command to the forwarding plane network element 1 to indicate that the sub-flow of the 3GPP access mode is adjusted to an idle state.

S906: The forwarding plane network element 1 sends a first indication message to the UE and the server respectively, and indicates that the sub-flow of the 3GPP access mode is adjusted to an idle state.

In this step, the forwarding plane network element 1 sends a first indication message to the UE and the server, where the sub-flow status update indication is carried. The first indication message indicates that the UE has adjusted the sub-flow status of the 3GPP connection to an idle state, for example, the sub-flow status update indication may be identified by defining an MPTCP Option MP_ACTIVE=1.

S907 to S909 are the same as S303 to S305 in the foregoing embodiment shown in FIG.

S910: The forwarding plane network element 2 detects the traffic of the substream of the WIFI access mode.

S911: The forwarding plane network element 2 detects that the traffic of the sub-flow in the WIFI access mode exceeds a certain threshold. The first status indication message is sent to the control plane network element.

In the above step, the forwarding plane network element 2 detects that the traffic of a certain sub-flow in the WIFI access mode exceeds a certain threshold, and reports the flow of the sub-flow to the control plane network element, that is, the forwarding plane network element 2 sends the indication of the carried sub-flow status. The first status indication message is sent to the control plane network element.

S912: The control plane network element sends a first state update command to the forwarding plane network element 1 of the 3GPP access mode.

In this step, the control plane network element sends a first state update command carrying the sub-flow state update command to the forwarding plane network element 1 to instruct the path of the 3GPP access technology to be adjusted to the ACTIVE state.

S913: The control plane network element triggers the base station to page the UE, the UE exits the idle state, and the base station and the network reconstruct the air interface resource.

S914: The forwarding plane network element 1 sends a second indication message to the UE and the server respectively.

In the above steps, the UE exits the idle state, and the base station and the network reestablish the air interface resources. The forwarding plane network element 1 sends a second indication message carrying the sub-flow status update indication to the UE and the server, indicating that the UE and the server can send data through the sub-stream of the 3GPP access mode. For example, the substream status update indication can be identified by defining an MPTCP Option MP_ACTIVE=0.

S915: The server transmits the service data to the UE by using the sub-flow of the 3GPP access mode and the sub-flow of the WIFI access mode.

The UE and the server simultaneously use multiple sub-stream communication of multiple access technologies.

In the service flow routing method provided by the implementation, when the forwarding plane network element 1 detects that the traffic of the 3GPP connected to a certain sub-flow exceeds a certain threshold, the forwarding plane network element 1 sends a sub-flow traffic status indication message to the control plane network element. The control plane network element sends a sub-flow traffic status request message to the forwarding plane network element 2, and requests the forwarding plane network element 2 to report the traffic condition of the sub-flow of the WIFI access mode to the control plane network element. The forwarding plane network element 2 sends a sub-flow traffic status indication message to the control plane network element, and reports the traffic of the sub-flow in the WIFI access mode to the control plane network element. The control plane network element integrates the sub-flow traffic of each access mode, and sends a sub-flow status update command message to the forwarding plane network element 1, indicating that the sub-flow of the 3GPP access mode is adjusted to an idle state, or in the same manner The substream of the 3GPP access mode is adjusted to the ACTIVE state, and the state of the substream of the 3GPP access mode is dynamically adjusted. The state of the access technology path is adjusted by the control of the intermediate network element to achieve the effect of signaling reduction and route optimization.

The routing method is described by using the 3GPP and WIFI access modes as an example. The technical solutions of the present invention are not limited to the foregoing two access modes, the first access mode and the second access mode. The access mode may also be different for two types of 3GPP access. The following describes the service flow routing method by using 4G and 5G as examples.

FIG. 11 is a schematic diagram of another network architecture of the service flow routing method according to the present invention. FIG. 11b is an interaction flowchart of another specific implementation manner of the service flow routing method according to the embodiment of the present invention, as shown in FIG. 11a and FIG. 11b. The UE of the MPTCP technology simultaneously uses multiple substreams of the 4G and 5G access modes to communicate with the server. The steps of the service flow routing method provided by the implementation manner are:

S1001: The UE detects whether the 5G access mode meets the transmission requirement of the service.

S1002: The UE detects that the 5G access mode can meet the transmission requirements of all services, and sends a sub-flow status update indication to the server.

In the foregoing steps, the UE detects that the 5G access mode can meet the transmission requirement of all services, and the UE sends a sub-flow status update indication to the server of the sub-flow of the 5G access mode that communicates with the UE (corresponding to the first in the foregoing embodiment). The indication message) indicates that the substream state of the 4G access mode is adjusted to an idle state. For example: This indication can be identified by defining an MPTCP Option MP_ACTIVE=1.

After receiving the indication message, the server does not use the sub-flow of the 4G access mode to transmit the service data of the UE, and only uses the sub-flow of the 5G access mode to transmit the service data.

Optionally, the UE sends a TCP keepalive message to the server of the sub-stream of the 4G access mode that communicates with the UE, and after receiving the response of the server after the preset time, determining that the server no longer communicates with the UE that communicates with the UE. The substream of the access method sends data.

S1003: The base station does not detect the packet for a long time.

S1004: The base station initiates air interface resource release.

In this step, the 4G base station does not detect the packet for a long time, and the 4G base station initiates the release of the 4G side air interface resource.

S1005: The UE detects that the traffic on a certain sub-flow of the 5G access mode exceeds the transmission capability of the 5G connection.

S1006: The UE exits the idle state, and the base station and the network re-establish the air interface resource.

In the above steps, when the UE detects that the traffic on a certain sub-flow of the 5G access mode exceeds the transmission capability of the 5G access, for example, the packet loss is relatively large, the UE exits the idle state on the 4G side, and the base station and the network re-establish 4G. Side air resource.

S1007: The UE sends a sub-flow status update indication to the server.

In this step, the UE sends a sub-flow status update indication to the server of the sub-flow of the 5G access mode with which the UE communicates, indicating that the server can send data through the sub-flow of the 4G access mode. For example: This indication can be identified by defining an MPTCP Option MP_ACTIVE=0.

After the UE re-enables the substream of the 4G access mode, the UE and the server simultaneously use multiple substream communication of multiple access technologies. In this solution, the UE sends a sub-flow status update indication message to the server of the sub-flow of the 5G access mode that communicates with the service according to the transmission requirement of the service, so as to dynamically adjust the state of the sub-flow of the 4G access mode, so that the sub-flow is not closed. On the premise, ensure that a specific access side can enter the idle mode normally, and avoid waste of cellular network air interface resources.

Optionally, the sub-flow status update indication message is sent through the sub-flow of the 4G connection, and the state of the 4G access technology sub-flow is dynamically adjusted, so that the specific access side can normally enter the idle state without closing the sub-flow. Mode to avoid waste of cellular network air interface resources.

The service flow routing method provided by the implementation manner, the UE detects that the 5G access mode can meet the transmission requirement of all services according to the bandwidth requirement and the service QoS priority requirement, and the UE sends the sub-flow status update to the server of the 5G connection sub-flow that communicates with the UE. The indication indicates that the sub-flow state of the 4G connection is adjusted to the idle state, the 4G base station does not detect the packet for a long time, and the 4G base station initiates the release of the 4G-side air interface resource. The sub-flow of the 4G access mode is adjusted to the idle mode without turning off the sub-flow, and the cellular air interface resource is saved.

Moreover, when the UE detects that the traffic on a certain sub-flow of the 5G access mode exceeds the transmission capability of the 5G connection, the UE exits the idle state of the 4G side, and the base station and the network reestablish the 4G side air interface resource. The UE sends a sub-flow status update indication to the server of the sub-flow of the 5G access mode with which the UE communicates, indicating that the server can send data through the sub-flow of the 4G access mode. To avoid the need to re-use the access technology, it is necessary to initiate the establishment of the corresponding sub-flow, which reduces the number of processing signaling by the UE and the server, and optimizes the process.

The routing method of the service flow provided by the present invention can also be used for state control of other multi-path transmission protocols, and is not limited to the MPTCP protocol.
