[0036] The network device in the embodiment of the present application may be a device for communicating with a UE, and the network device may also be referred to as an access network device or a radio access network device, such as a base station. The network device in the embodiment of the present application may refer to a radio access network (RAN) node (or device) that accesses a UE to a wireless network. The base station can broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof.

The network device and the scenarios in which the embodiments of the present application are located are not limited in the embodiments of the present application.

[0039] It should also be understood that all or part of the functions of the network device and UE in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (eg, a cloud platform).

[0040] Combine the following Figure 2 A system architecture in an embodiment of the present application is described.

[0041] Figure 2 This is the 5GS (5G system) architecture diagram, which includes: network slice specific authentication and authorization function (NSSAAF), network slice selection function (NSSF), authentication server function (AUSF), unified data management (UDM), network slice admission control function (NSACF), access and mobility management function (AMF), session management function (SMF), policy control function (PCF), application function (AF), UE, radio access network (RAN), user plane function (UPF), data network (DN) and other network elements.

[0042] The embodiments of the present application involve terminal equipment (UE), access network elements (RAN), control plane elements (e.g., PCF, SMF, etc.), user plane elements (e.g., UPF), and application servers (AS). DN can implement the functions of the user plane part of the application server, and AF can implement the functions of the control plane part of the application server. Optionally, the access network element can be Figure 1 The network device 110 and the terminal device in the embodiment can be Figure 1 The terminal device 120 in.

[0043] The XRM service flow has a certain periodicity. For example, the server can send video frames of the XRM service at a certain frame rate. Access network equipment (such as RAN or next generation radio access network (NG-RAN)) can optimize the connected mode discontinuous reception (CDRX) configuration according to the period of the service flow to achieve device node management. However, due to multipath routing and coding complexity between the server and the core network elements (such as 5G core network (5GC) elements), the video frames of the XRM service may not be able to reach the access network device according to the predetermined period. Therefore, while providing the service flow period to the access network device, it is also necessary to provide the N6 jitter information corresponding to the service flow period (such as the jitter information between DN and UPF) to the access network device, thereby assisting the access network device to optimize the CDXR configuration.

[0044] The existing standard only proposes that SMF requests UPF to obtain the N6 jitter range of a given period, and 5GC derives the jitter information accordingly and forwards it to the access network equipment together with the period information. However, it is not clear how to obtain the jitter information corresponding to the service flow. For example, it is not clear when SMF requests the N6 jitter range of a given period, what information SMF sends to assist UPF in determining the target service flow to be detected, and how UPF forwards the information to the access network equipment after measuring the N6 jitter range.

[0045] In order to solve one or more of the above technical problems, the present application proposes a communication method and a communication device.

[0046] Combine the following Figures 3 to 7 The embodiments of the present application are described in detail with examples.

[0047] Figure 3 It is a schematic flowchart of the communication method of an embodiment of the present application. Figure 3 The method 300 shown may include step S320, which is as follows:

[0048] S320: The first network entity sends first information to the second network entity.

[0049] The first network entity may be an SMF, and the second network entity may be a UPF.

[0050] Optionally, the first information may be used to request the second network entity to determine jitter information corresponding to the target service flow. The jitter information may include at least one of the following information: jitter range, jitter average value, and jitter variance.

[0051] Optionally, the jitter information corresponding to the target service flow may be N6 jitter information, for example, the jitter information of the target service flow between the UPF and the DN.

[0052] Optionally, the first information may include at least one of the following information: a jitter information acquisition indication, period information of the target service flow, and flow description information of the target service flow.

[0053] Optionally, the period information of the target service flow may be a period of a data burst of the target service flow.

[0054] Optionally, the flow description information may include at least one of the following information: packet filtering information of an Internet Protocol (IP) quintuple, an application identifier corresponding to a target service flow, an identifier (ID) of a target UE corresponding to the target service flow, an address of the target UE, and header information of a data packet corresponding to the target service flow. The packet filtering information of the IP quintuple may include a source address, a source port number, a destination address, a destination port number, and a supported protocol identifier (ID).

[0055] In an embodiment of the present application, a first network entity sends first information to a second network entity, and the first information is used to request the second network entity to determine jitter information corresponding to a target service flow, which helps the second network entity to determine the jitter information corresponding to the target service flow based on the first information, and further helps the access network device to optimize the CDRX configuration based on the jitter information corresponding to the target service flow.

Optionally, the second information may include at least one of the following information: a jitter information acquisition indication, period information of a target service flow, and flow description information of a target service flow. The jitter information acquisition indication may instruct the first network entity to send the first information.

[0059] The second information may trigger the first network entity to send the first information in an explicit or implicit manner. For example, if the first information includes a jitter information acquisition indication, it is equivalent to the second information triggering the first network entity to send the first information in an explicit manner; if the first information includes the period information of the target service flow and / or the flow description information of the target service flow, it is equivalent to the second information triggering the first network entity to send the first information in an implicit manner.

[0060] Optionally, the third network entity may be an AF. Optionally, the third network entity may send the second information to the first network entity through the PCF. It should be noted that the AF can be divided into a trusted AF and an untrusted AF. If the third network entity is a trusted AF, the second message may be sent directly to the PCF, and then the PCF forwards the second information to the first network entity; if the third network entity is an untrusted AF, the second message needs to be sent to the PCF through a network exposure function (NEF), and then the PCF forwards the second information to the first network entity.

[0061] Optionally, the third network entity may be an access network device, such as a RAN or a NG-RAN. Optionally, the third network entity may send the second information to the first network entity through an AMF.

[0062] In some embodiments, after step S320, the method 300 may further include step S330, which is as follows:

[0063] S330: The second network entity determines jitter information corresponding to the target service flow according to the first information.

[0064] For example, the second network entity may determine the target service flow according to the period information of the target service flow or the flow description information of the target service flow, and obtain the N6 jitter information corresponding to the target service flow based on its own implementation.

[0065] In some embodiments, after step S320, the method 300 may further include step S340, which is as follows:

[0067] Optionally, the third information may include jitter information corresponding to the target service flow. Optionally, the third information may also include period information and / or flow description information of the target service flow.

[0068] In some embodiments, after step S320, the method 300 may further include step S350, which is as follows:

[0069] S350: The first network entity sends fourth information to the fourth network entity.

[0070] Optionally, the fourth information may include jitter information corresponding to the target service flow. Optionally, the fourth information may also include period information and / or flow description information of the target service flow.

[0071] Optionally, the fourth network entity may be an access network device. Optionally, after receiving the third information sent by the second network entity, the first network entity may send the fourth information to the fourth network entity through the AMF.

[0072] In some embodiments, after step S320, the method 300 may further include step S350, which is as follows:

[0073] S350: The second network entity sends fifth information to the fourth network entity.

[0074] Optionally, the fifth information may include jitter information corresponding to the target service flow. Optionally, the fifth information may also include period information and / or flow description information of the target service flow.

[0075] Optionally, the fourth network entity may be an access network device, such as a RAN or a NG-RAN. Optionally, the second network entity may send the fifth information to the fourth network entity via a user interface. For example, the fourth network entity may add the fifth information to a general packet radio service (GPRS) tunnel transport protocol user plane part (GTP-U) header of a data packet (corresponding to the target service flow), and send the data packet to the fourth network entity. Accordingly, the fourth network entity may read the GTP-U header of the data packet to obtain the fifth information.

[0076] Furthermore, the fourth network entity may optimize the CDRX configuration according to the jitter information corresponding to the target service flow.
