It selects and provides available policy and charging control decisions for the Policy and Charging Enforcement Function (PCEF).

[0058] Figure 2 FIG. shows a schematic block diagram of method 100 for determining a service path according to an embodiment of the present application. As Figure 2 shown, method 100 includes the following parts or all of the content:

[0059] S110, when the terminal device has accessed the network through a first service path, obtain the network load condition of the first service path.

[0060] S120, according to the network load condition, switch the service path for the terminal device to access the network from the first service path to a second service path.

[0061] Specifically, in the embodiment of the present application, the terminal device or the service access management node can periodically obtain the network load condition of the current service path. If the terminal device or the service access management node determines that the current network load condition meets the trigger condition, then the terminal device or the service access management node can directly switch the service path. For example, the terminal device currently accesses the network using LTE. Specifically, the terminal device currently accesses the service access management node using LTE and performs service transmission using LTE. When the terminal device determines that the network load condition of LTE is not good, such as the current service transmission fails for a long time, the terminal device can consider that the performance of the currently accessed network is poor and can choose to directly switch the terminal device to the WLAN system to transmit the currently ongoing service.

[0062] Therefore, the method for determining a service path according to the embodiment of the present application can trigger the switching of the service path for the terminal device to access the network by monitoring the network load condition of the current service path, and can improve the user experience of the terminal.

[0063] As mentioned above, the method according to the embodiments of the present application can be executed by a terminal device or by a service access management node. The service access management node can be a certain functional entity within the core network device or a device outside the core network device. For the sake of description convenience, in some places hereinafter, the terminal device will be used as an example to describe the present solution. However, it should be understood that the following various solutions are equally applicable to the service access management node.

[0064] Optionally, in the embodiments of the present application, the first service path is a non-3rd Generation Partnership Project (non-3GPP) access path, and the second service path is a 3GPP access path, or the first service path is a 3GPP access path, and the second service path is a non-3GPP access path. For example, the first service path can be an LTE network, and the second service path can be a WLAN network. The first service path and the second service path can also be service paths other than the above-mentioned 3GPP access path and non-3GPP access path. The embodiments of the present application do not impose any limitations on this.

[0065] Optionally, in the embodiments of the present application, switching the service path for the terminal device to access the network from the first service path to the second service path according to the network load condition includes: if the network on the first service path is unavailable, switching the service path for the terminal device to access the network from the first service path to the second service path.

[0066] Specifically, the terminal device can periodically obtain the current network load condition. For example, after the terminal device sends a service to the network, it can immediately start a timer. If the timer times out and the terminal device does not receive a response from the network side, it can be considered that the network on the current service path is unavailable. Then the terminal device can switch the current service path to another service path. The present application does not impose any limitations on how the terminal device learns that the network on the current service path is unavailable.

[0067] Optionally, in the embodiments of the present application, switching the service path for the terminal device to access the network from the first service path to the second service path according to the network load condition includes: switching the service path for the terminal device to access the network from the first service path to the second service path according to a generated random value and a first network access probability, where the first network access probability is used to indicate the probability that the network on the first service path allows the terminal device to access.

[0068] Specifically, the network device can broadcast a series of access probabilities and access delays for different access classes to the terminal device through a system message. After obtaining these access probabilities, the terminal device will generate a random value between 0 and 1 and compare it with the obtained access probability. If it is within the access probability range, the terminal device can continue to use the current service path without switching to access the network. If the generated random value is greater than the obtained access probability, the terminal device can switch the current service path to another service path.

[0069] As mentioned above, the terminal device can obtain a series of access probabilities from the system message or broadcast message. The access probability may be for different terminal devices. The terminal device can first determine which access probability is for itself. For example, the message carrying the access probability can carry the identifier of the terminal device. Then, after the terminal device receives the message, it can know whether the access probability in the message is for itself according to the terminal identifier inside.

[0070] Optionally, the terminal device can determine the first network access probability according to the attributes of the terminal device.

[0071] Specifically, the attributes of the terminal device can be the access class, the type of the terminal device, or the priority of the terminal device, etc. For example, the network can pre-configure different access classes corresponding to different network access probabilities. Each terminal device has its own access class. After the terminal device obtains its own access class, it can find the access probability corresponding to itself according to the corresponding relationship configured by the network. For another example, the network can pre-configure different types of terminals corresponding to different network access probabilities. Each terminal device can find the network access probability corresponding to itself according to its own type and the corresponding relationship configured by the network. For another example, the network can pre-configure different priorities of terminal devices corresponding to different network access probabilities. The terminal device can find the network access probability corresponding to itself in the corresponding relationship configured by the network according to its own priority.

[0072] It should be understood that in the embodiments of the present application, the above is described by taking various attributes of the terminal device such as the access class, the type of the terminal device, or the priority of the terminal device as examples, and the embodiments of the present application should not be limited thereto.

[0073] Optionally, the terminal device can determine the first network access probability according to the service attributes of the current service of the terminal device.

[0074] Specifically, the service attribute of the current service of the terminal device may be the application type of the service, the Quality of Service (QoS) level of the service, the priority of the service, or the access level of the service, etc. For example, the network can pre-configure different application types to correspond to different network access probabilities. Each service has its own application type. After the terminal device obtains the application type of the current service, it can, according to the corresponding relationship configured by the network, find the access probability corresponding to the current service. For another example, the network can pre-configure different QoS levels of the service to correspond to different network access probabilities. The terminal device can, according to the QoS level of the current service and the corresponding relationship configured by the network, find the network access probability corresponding to the QoS level of the current service. For another example, the network can pre-configure different priorities of the service to correspond to different network access probabilities. The terminal device can, according to the priority of its current service in the corresponding relationship configured by the network, find the network access probability corresponding to the current service. For another example, the network can pre-configure different access levels of the service to correspond to different network access probabilities. The terminal device can, according to the access level of its current service and the corresponding relationship configured by the network, find the network access probability corresponding to the current service.

[0075] It should be understood that in the embodiments of the present application, the above is described by taking various service attributes such as the application type, the QoS level of the service, the priority of the service, or the access level of the service as examples, and the embodiments of the present application should not be limited thereto.

[0076] It should also be understood that the above various corresponding relationships can be network configurations, can also be preset in the terminal device by using protocol agreements, or can be agreed upon by the terminal device and the operator through a contract.

[0077] Optionally, in the embodiments of the present application, the method is executed by the terminal device, and obtaining the first network access probability includes: obtaining the first network access probability through the core network or the access network on the first service path.

[0078] Optionally, in the embodiments of the present application, the method is executed by the service access management node, and obtaining the first network access probability includes: obtaining the first network access probability through the core network, the access network on the first service path, or the Operation Maintenance (OM) network.

[0079] It should be understood that the above network access probability can be the access probability of the access network or the access probability of the core network, and the embodiments of the present application do not limit this.

[0080] Figure 3 Shows a schematic block diagram of a method 200 for determining a service path according to an embodiment of the present application. As Figure 3As shown, the method 200 can be executed by a terminal device or a service access management node. The method 200 includes the following parts or all of the content:

[0081] S210, obtaining the network load status of the first service path among multiple service paths;

[0082] S220, determining a target service path for the service to be initiated by the terminal device from the multiple service paths according to the network load status;

[0083] S230, accessing the network by the terminal device through the target service path.

[0084] Specifically, in the embodiments of the present application, before initiating a service, the terminal device may first determine whether a service path meets the requirements according to the network load status on a certain service path. If the service path meets the requirements, it can be considered that the service path can be used to transmit the service. If the service path does not meet the requirements, it can be considered that the service path cannot be used to transmit the service. Then the terminal device can use another service path to transmit the service. For example, before initiating a service, the terminal device may first determine the network load status on LTE. If the network load status on LTE is not good, the terminal device can directly select WLAN to transmit the service.

[0085] Therefore, the method for determining a service path in the embodiments of the present application can improve the user experience of the terminal by determining the service path for the terminal device to access the network according to the network load status on a certain service path.

[0086] As mentioned above, the method in the embodiments of the present application can be executed by a terminal device or a service access management node. The service access management node can be a certain functional entity within the core network device or a device outside the core network device. For the convenience of description, the terminal device will be used as an example to describe the present solution in some places below. However, it should be understood that the following various solutions are equally applicable to the service access management node.

[0087] Optionally, in the embodiments of the present application, the target service path includes a non-3rd Generation Partnership Project (3GPP) access path or a 3GPP access path. For example, the target service path can be an LTE network, and the target service path can also be a WLAN network. The target service path can also be a service path other than the above 3GPP access path and non-3GPP access path. The embodiments of the present application do not limit this.

[0088] For example, before initiating a service, a terminal device may obtain the network load status of a certain service path from another terminal device. The other terminal device may be provided with network services by an access network device in the cell where the terminal device is located. This application embodiment does not limit how the terminal device obtains the network load status of a certain service path.

[0089] Optionally, in the embodiments of this application, determining the target service path for the service to be initiated by the terminal device from the multiple service paths according to the network load status includes: if the network on the first service path is unavailable, determining that the target service path is the second service path among the multiple service paths; if the network on the first service path is available, determining that the target service path is the first service path.

[0090] Specifically, before initiating a service, the terminal device obtains the network load status of the first service path. For example, before initiating a service, the terminal device sends a request to other terminal devices in the same cell as the terminal device, requesting the other terminal devices to inform itself whether the 3GPP access network in the cell is available. After receiving the request from the terminal device, the other terminal devices can notify the terminal device whether the 3GPP access network is available. Then, the terminal device can determine whether to access the network directly through the 3GPP access network or through the non-3GPP access network according to whether the 3GPP access network is available.

[0091] Optionally, in the embodiments of this application, determining the target service path for the service to be initiated by the terminal device from the multiple service paths according to the network load status includes: determining the target service path according to a generated random value and a first network access probability, where the first network access probability is used to indicate the probability that the network on the first service path allows the terminal device to access.

[0092] Specifically, the network device may broadcast a series of access probabilities and access delays of different access levels to the terminal device through a system message. After obtaining these access probabilities, the terminal device generates a random value between 0 and 1 and compares it with the obtained access probability. If it is within the access probability range, the terminal device can directly use the current service path for judgment to access the network. If the generated random value is greater than the obtained access probability, the terminal device can use another service path to access the network.

[0093] As mentioned above, the terminal device can obtain a series of access probabilities from system messages or broadcast messages. These access probabilities may be for different terminal devices. The terminal device can first determine which access probability is for itself. For example, the message carrying the access probability may carry the identifier of the terminal device. Then, after the terminal device receives the message, it can know whether the access probability in the message is for itself based on the terminal identifier inside.

[0094] Optionally, in the embodiments of this application, the terminal device can determine the first network access probability according to the attributes of the terminal device.

[0095] Specifically, the attributes of the terminal device can be access level, type of the terminal device, or priority of the terminal device, etc. For example, the network can pre-configure different access levels corresponding to different network access probabilities. Each terminal device has its own access level. After the terminal device obtains its own access level, it can find the access probability corresponding to itself according to the corresponding relationship configured by the network. For another example, the network can pre-configure different types of terminals corresponding to different network access probabilities. Each terminal device can find the network access probability corresponding to itself according to its own type and the corresponding relationship configured by the network. For yet another example, the network can pre-configure different priorities of terminal devices corresponding to different network access probabilities. The terminal device can find the access probability corresponding to itself in the corresponding relationship configured by the network according to its own priority.

[0096] It should be understood that in the embodiments of this application, the above takes various attributes of the terminal device such as access level, type of the terminal device, or priority of the terminal device as examples for description, and the embodiments of this application should not be limited thereto.

[0097] Optionally, the terminal device can determine the first network access probability according to the service attributes of the current service of the terminal device.

[0098] Specifically, the service attributes of the current service of the terminal device may be the application type of the service, the Quality of Service (QoS) level of the service, the priority of the service, or the access level of the service, etc. For example, the network can pre-configure different application types to correspond to different network access probabilities. Each service has its own application type. After the terminal device obtains the application type of the current service, it can, according to the corresponding relationship configured by the network, find the access probability corresponding to the current service. For another example, the network can pre-configure different QoS levels of the service to correspond to different network access probabilities. The terminal device can, according to the QoS level of the current service and the corresponding relationship configured by the network, find the network access probability corresponding to the QoS level of the current service. For another example, the network can pre-configure different priorities of the service to correspond to different network access probabilities. The terminal device can, according to the priority of its current service, find the network access probability corresponding to the current service in the corresponding relationship configured by the network. For another example, the network can pre-configure different access levels of the service to correspond to different network access probabilities.
