Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method and apparatus for service access. Background Technology

[0002] In 5G systems, terminal devices can access services through 3GPP (3rd Generation Partnership Project) networks or non-3GPP networks. Specifically, there is a service access management node on the network side, which is responsible for managing services accessed through 3GPP or non-3GPP networks.

[0003] Therefore, for terminal devices or service access management nodes, how to achieve effective service access is an urgent problem to be solved. Summary of the Invention

[0004] This application provides a method and device for service access, which facilitates effective service access.

[0005] Firstly, a method for service access is provided, including:

[0006] The first device determines the reception status of the first data packet transmitted through the first service path;

[0007] The first device determines whether the first service path is available based on the reception status of the first data packet.

[0008] Therefore, in the service access method of this application embodiment, the first device can determine whether the first service path for service access is available before performing service access, which is beneficial to selecting an available service path for access, thereby realizing effective access to the terminal's services.

[0009] In one embodiment, when the first service path is available, service access can be performed using the first service path. When the first service path is unavailable, other service paths can be selected for access, or access can be performed through the first service path after load reduction. Therefore, effective access to the terminal's services can be achieved, thereby improving the user experience.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the first device is the sender of the first data packet and the second device is the receiver of the first data packet; or the first device is the receiver of the first data packet and the second device is the sender of the first data packet.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the first device is a terminal device and the second device is a network device; or the first device is a network device and the second device is a terminal device.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the network device is a service function management node or a user plane function (UPF) entity.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes:

[0014] The first device sends the first data packet to the second device at a specific period, or receives the first data packet sent by the second device.

[0015] In conjunction with the first aspect, in certain implementations of the first aspect, the first device sends the first data packet to the second device at a specific period, including:

[0016] The first device sends the first data packet to the second device according to the specific period when the first preset condition is met.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, the specific period is agreed upon by the first device and the second device; or, if the first device is a terminal device and the second device is a network device, the specific period is configured by the second device.

[0018] In other words, the first device and the second device can determine the transmission period of the first device, i.e. the specific period mentioned above, through message interaction. Alternatively, if the first device is a terminal device and the second device is a network device, the specific period is configured by the second device. That is, the second device can configure the transmission period of the first data packet for the first device. For example, the second device can send a first message to the first device to configure the transmission period of the first data packet for the first device. The first message can be semi-static signaling (e.g., Radio Resource Control (RRC) message) or dynamic signaling (e.g., Downlink Control Information (DCI)).

[0019] Alternatively, the specific period can be agreed upon by the protocol, so that there is no need for information exchange between the first device and the second device. The sending end can send the first data packet according to the sending period agreed upon by the protocol, and the receiving end can also receive the first data packet according to the sending period predetermined by the protocol.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the data stream or bearer used to transmit the first data packet has a corresponding relationship with the transmission period of the first data packet.

[0021] For example, the data stream used to transmit the first data packet and the transmission period of the first data packet can be in a one-to-one correspondence or a many-to-one correspondence, etc. Similarly, the bearer used to transmit the first data packet and the transmission period of the first data packet can also be in a one-to-one correspondence or a many-to-one correspondence, etc.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the first device is the sender of the first data packet, and the first device determines the reception status of the first data packet transmitted through the first service path, including:

[0023] The first device receives the reception status of the first data packet reported by the second device;

[0024] The first device determines whether the first service path is available based on the reception status of the first data packet, including:

[0025] The first device determines whether the first service path is available based on the reception status of the first data packet reported by the second device.

[0026] In conjunction with the first aspect, in certain implementations of the first aspect, the first device determines whether the first service path is available based on the reception status of the first data packet, including:

[0027] The first device determines that the first service path is unavailable when at least one of the following conditions is met:

[0028] The following conditions are met: the first data packet is not received correctly within a specific time period of the receiving cycle; the number of data packets correctly received within the receiving window is lower than a first preset value; the ratio of correctly received data packets to all received data packets within the receiving window is lower than a second preset value; the ratio of incorrectly received data packets to all received data packets within the receiving window is higher than a third preset value; the ratio of incorrectly received data packets to correctly received data packets within the receiving window is higher than a fourth preset value; and the ratio of correctly received data packets to incorrectly received data packets within the receiving window is lower than a fifth preset value.

[0029] In one embodiment, the first, second, third, fourth, and fifth preset values ​​can be system-set or determined based on the service requirements of the service to be accessed. For example, if the service to be accessed has high requirements for link quality, then the first preset value can be set to a larger value, the second preset value can be set to a smaller value, the third preset value can be set to a smaller value, the fourth preset value can be set to a smaller value, and the fifth preset value can be set to a larger value. Conversely, if the service to be accessed has low requirements for link quality, then the first preset value can be set to a smaller value, the second preset value can be set to a larger value, the third preset value can be set to a larger value, the fourth preset value can be set to a larger value, and the fifth preset value can be set to a smaller value.

[0030] In conjunction with the first aspect, in some implementations of the first aspect, the first device is a terminal device or a UPF entity. After the first device determines that the first service path is unavailable, the method further includes:

[0031] The first device sends status information to the service function management node. The status information is used to indicate that the first service path is unavailable, so that the service function management node can switch the service to be accessed to another service path other than the first service path, or initiate a request message to release the first service path.

[0032] Therefore, in the service access method of this application embodiment, the first device can notify the service function management node that the first service path is unavailable when the first service path is unavailable. The service function management node can then switch the service to be accessed by the terminal device to another service path, or release the first service path, and then access the service to be accessed initiated by the terminal device through the first service path, thereby achieving effective service access and improving user experience.

[0033] In conjunction with the first aspect, in some implementations of the first aspect, the first device is a service function management node. After the first device determines that the first service path is unavailable, the method further includes:

[0034] The first device switches the service to be accessed to a service path other than the first service path, or initiates a request message to release the first service path.

[0035] Therefore, in the service access method of this application embodiment, the first device can switch the service to be accessed by the terminal device to another service path or release the first service path when the first service path is unavailable, and then access the service to be accessed initiated by the terminal device through the first service path, thereby achieving effective service access and improving user experience.

[0036] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes:

[0037] If the first device determines that the first service path is available, the first device accesses the service to be accessed through the first service path.

[0038] In conjunction with the first aspect, in certain implementations of the first aspect, the first data packet includes a sequence number, and the first device determines the reception status of the first data packet transmitted through the first service path, including:

[0039] The first device determines the reception status of the first data packet based on the sequence number of the received first data packet.

[0040] In conjunction with the first aspect, in some implementations of the first aspect, the first business path is a 3GPP path or a non-3GPP path.

[0041] For example, if the first service path is a 3GPP path, the service to be accessed can be accessed through a 3GPP network (e.g., a long term evolution (LTE) network or a 5G network, etc.), or if the first service path is a non-3GPP path, the service to be accessed can be accessed through a non-3GPP network, such as a wireless local area network (WLAN).

[0042] In summary, the service access method of this application embodiment can, when the first service path is available, use the first service path to access the service to be accessed initiated by the terminal device; when the first service path is unavailable, other service paths can be used to access the service to be accessed initiated by the terminal device, or some or all services on the first service path can be stopped, and then the first service path can be used to access the service to be accessed initiated by the terminal device.

[0043] Secondly, a service access device is provided for executing the methods described in the first aspect or any possible implementation thereof. Specifically, the device includes units for executing the methods described in the first aspect or any possible implementation thereof.

[0044] Thirdly, a service access device is provided, comprising: a memory, a processor, an input interface, and an output interface. The memory, processor, input interface, and output interface are connected via a bus system. The memory stores instructions, and the processor executes the instructions stored in the memory to perform the methods described in the first aspect or any possible implementation thereof.

[0045] Fourthly, a computer storage medium is provided for storing computer software instructions for performing the methods of the first aspect or any possible implementation thereof, comprising a program designed for performing the aspects.

[0046] Fifthly, a computer program product including instructions is provided, which, when run on a computer, causes the computer to perform the method of the first aspect or any optional implementation thereof. Attached Figure Description

Alternatively, the network device may be a relay station, access point, vehicle-mounted equipment, wearable device, network-side equipment in a future 5G network, or network equipment in a future evolved Public Land Mobile Network (PLMN), etc.

[0055] The wireless communication system 100 also includes at least one terminal device 120 located within the coverage area of ​​the network device 110. The terminal device 120 can be mobile or fixed. In one embodiment, the terminal device 120 can refer to an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device.

[0056] In one embodiment, the terminal devices 120 can perform device-to-device (D2D) communication.

[0057] In one implementation, the 5G system or network may also be referred to as a New Radio (NR) system or network.

[0058] Figure 1 An exemplary diagram shows a network device and two terminal devices. In one embodiment, the wireless communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application does not limit the scope of the embodiments.

[0059] In one embodiment, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this application embodiment.

[0060] In the communication system of this application embodiment, the terminal device can access services through a 3GPP network (e.g., an LTE network or a future 5G network) or a non-3GPP network (e.g., a Wireless Local Area Network, WLAN). The service access management node on the network device side can manage the services accessed through the 3GPP network or the non-3GPP network. For the service access management node, how to achieve effective service access is an urgent problem to be solved.

[0061] Figure 2The present application schematically illustrates a service access method 200 provided in an embodiment of the present application. This method 200 can be applied to the aforementioned wireless communication system 100, but the embodiments of the present application are not limited thereto.

[0062] like Figure 2 As shown, the method 200 includes the following:

[0063] S210, the first device determines the reception status of the first data packet transmitted through the first service path;

[0064] S220, the first device determines whether the first service path is available based on the reception status of the first data packet.

[0065] In this embodiment of the application, the first device is the sender of the first data packet and the second device is the receiver of the first data packet; or the first device is the receiver of the first data packet and the second device is the sender of the first data packet.

[0066] In the embodiments of this application, the first device is a terminal device and the second device is a network device; or the first device is a network device and the second device is a terminal device.

[0067] The network device is a service function management node or a user plane function (UPF) entity.

[0068] Specifically, if the first device is the receiving end of the first data packet, then the first device can determine whether the first service path is available based on its reception status of the first data packet transmitted through the first service path. Alternatively, if the first device is the sending end of the first data packet, then the receiving end of the first data packet is designated as the second device, which can report the reception status of the first data packet to the first device. The first device can then determine whether the first service path is available based on the reception status of the first data packet reported by the second device. Further, if the first service path is available, the first device uses the first service path to access the service to be accessed. Or, if the first service path is unavailable, the first device accesses the service to be accessed through another service path. Alternatively, it can release or stop some or all services on the first service path, i.e., reduce the load on the first service path, and then access the service to be accessed through the first service path.

[0069] Therefore, in the service access method of this application embodiment, the first device can determine whether the first service path for service access is available before performing service access. If it is available, service access is performed. If it is unavailable, other service paths are selected for access, or access is performed through the first service path after reducing the load. Therefore, effective access to the terminal's services can be achieved, thereby improving the user experience.

[0070] In one implementation, and in some possible embodiments, the first data packet includes a sequence number, and the first device determines the reception status of the first data packet transmitted via the first service path, including:

[0071] The first device determines the reception status of the first data packet based on the sequence number of the received first data packet.

[0072] The first data packet includes a sequence number, so the receiving end of the first data packet can determine whether the received data packet is correct based on the sequence number, and thus determine the reception status of the first data packet.

[0073] As a specific embodiment, the first device determines whether the first service path is available based on the reception status of the first data packet, including:

[0074] The first device determines that the first service path is unavailable when at least one of the following conditions is met:

[0075] The following conditions are met: the first data packet is not received correctly within a specific time period of the receiving cycle; the number of data packets correctly received within the receiving window is lower than a first preset value; the ratio of correctly received data packets to all received data packets within the receiving window is lower than a second preset value; the ratio of incorrectly received data packets to all received data packets within the receiving window is higher than a third preset value; the ratio of incorrectly received data packets to correctly received data packets within the receiving window is higher than a fourth preset value; and the ratio of correctly received data packets to incorrectly received data packets within the receiving window is lower than a fifth preset value.

[0076] It should be noted that the receiving period here can correspond to the sending period of the first data packet described below, that is, the sending end of the first data packet sends the first data packet to the receiving end of the first data packet according to the sending period, and the receiving end of the first data packet receives the first data packet sent by the sending end of the first data packet according to the receiving period.

[0077] It should be understood that the first, second, third, fourth, and fifth preset values ​​can be system-set or determined based on the service requirements of the service to be accessed. For example, if the service to be accessed has high requirements for link quality, then the first preset value can be set to a larger value, the second preset value can be set to a smaller value, the third preset value can be set to a smaller value, the fourth preset value can be set to a smaller value, and the fifth preset value can be set to a larger value. Conversely, if the service to be accessed has low requirements for link quality, then the first preset value can be set to a smaller value, the second preset value can be set to a larger value, the third preset value can be set to a larger value, the fourth preset value can be set to a larger value, and the fifth preset value can be set to a smaller value.

[0078] It should be noted that if the first device is the receiving end of the first data packet, the reception status of the first data packet can be determined by the first device; or if the first device is the sending end of the first data packet, the reception status of the first data packet can be reported to the first device by the sending end of the first data packet, i.e., the second device. In short, the first device can determine whether the first service path is available based on the reception status of the first data packet.

[0079] In one implementation, in some possible embodiments, if the first device is a terminal device or a UPF entity, after the first device determines that the first service path is unavailable, the method 200 may further include:

[0080] The first device sends status information to the service function management node. The status information is used to indicate that the first service path is unavailable, so that the service function management node can switch the service to be accessed to another service path other than the first service path, or initiate a request message to release the first service path.

[0081] In the case where the first device is a terminal device or a UPF entity, if the first device determines that the first service path is unavailable, the first device can send status information to the service function management node to notify the service function management node that the first service path is unavailable. In this way, when the terminal device initiates a service to be accessed, the service function management node will switch the service to be accessed to another service path, that is, access the terminal device's service to be accessed through another service path. Alternatively, the first device can initiate a request message to release the first service path, that is, request to release the first service path. In this way, the first device can access the service to be accessed initiated by the terminal device through the first service path.

[0082] Therefore, in the service access method of this application embodiment, the first device can notify the service function management node that the first service path is unavailable when the first service path is unavailable. The service function management node can then switch the service to be accessed by the terminal device to another service path, or release the first service path, and then access the service to be accessed initiated by the terminal device through the first service path, thereby achieving effective service access and improving user experience.

[0083] In one embodiment, the first device is a service function management node. After the first device determines that the first service path is unavailable, the method further includes:

[0084] The first device switches the service to be accessed to a service path other than the first service path, or initiates a request message to release the first service path.

[0085] Therefore, in the service access method of this application embodiment, the first device can switch the service to be accessed by the terminal device to another service path or release the first service path when the first service path is unavailable, and then access the service to be accessed initiated by the terminal device through the first service path, thereby achieving effective service access and improving user experience.

[0086] In one embodiment, in some possible embodiments, the method 200 further includes:

[0087] If the first device determines that the first service path is available, the first device accesses the service to be accessed through the first service path.

[0088] In other words, the service access method of this application embodiment can use the first service path to access the service initiated by the terminal device when the first service path is available, and can use other service paths to access the service initiated by the terminal device when the first service path is unavailable, or stop some or all services on the first service path and then use the first service path to access the service initiated by the terminal device.

[0089] In one embodiment, the first service path is a 3GPP path or a non-3GPP path.

[0090] If the first service path is a 3GPP path, the service to be accessed can be accessed through a 3GPP network (e.g., an LTE network or a 5G network, etc.). Alternatively, if the first service path is a non-3GPP path, the service to be accessed can be accessed through a non-3GPP network, such as WLAN.

[0091] In one embodiment, in some embodiments, the method 200 further includes:

[0092] The first device sends the first data packet to the second device at a specific period, or receives the first data packet sent by the second device.

[0093] In one embodiment, the specific period is agreed upon by the first device and the second device. For example, the first device and the second device can determine the transmission period of the first device, i.e., the specific period mentioned above, through message interaction. Alternatively, if the first device is a terminal device and the second device is a network device, the specific period is configured by the second device. That is, the second device can configure the transmission period of the first data packet for the first device. For example, the second device can send a first message to the first device to configure the transmission period of the first data packet for the first device. The first message can be semi-static signaling (e.g., Radio Resource Control (RRC) message) or dynamic signaling (e.g., Downlink Control Information (DCI)).

[0094] Alternatively, the specific period can be agreed upon by the protocol, so that there is no need for information exchange between the first device and the second device. The sending end can send the first data packet according to the sending period agreed upon by the protocol, and the receiving end can also receive the first data packet according to the sending period predetermined by the protocol.

[0095] In one specific embodiment, the first device sends the first data packet to the second device at a specific period, including:

[0096] The first device sends the first data packet to the second device according to the specific period when the first preset condition is met.

[0097] That is, the first device can send the first data packet at a specific period under the condition of meeting the first preset condition. For example, the first device can start sending the first data packet periodically when the link quality of the first service path is poor.

[0098] In one embodiment, in some possible embodiments, the data stream or bearer used to transmit the first data packet has a corresponding relationship with the transmission period of the first data packet.

[0099] For example, the data stream used to transmit the first data packet and the transmission period of the first data packet can be in a one-to-one correspondence or a many-to-one correspondence, etc. Similarly, the bearer used to transmit the first data packet and the transmission period of the first data packet can also be in a one-to-one correspondence or a many-to-one correspondence, etc.
