Problems solved by technology

[0004] However, in the MEC scenario, if the MEC is deployed at the sinking UPF, since the deployment positions of the access and mobility management function (AMF) and the policy control function (PCF) are relatively high (that is, far from the user), if still follow the existing path (radio access network (radio access network, RAN) RAN--AMF--session management function (SMF)--PCF--application Function (Application Function, AF)) to report user plane information, due to the long reporting path, AF or PCF may not be able to make code rate or policy adjustments in time based on RAN information, which will affect packet transmission, such as packet loss , affecting user experience

Embodiment 1

[0140] The embodiment of this application provides a method for reporting user plane information, such as Figure 4 As shown, the method includes:

[0141] S401: The session management network element acquires parameter information, the session management network element initiates the establishment of a dedicated tunnel between the first communication device and the second communication device, and the dedicated tunnel is used to transmit user plane information; the parameter information is used for session management network element indication The first communication device reports the user plane information when the reporting condition is met.

[0142] Wherein, if the first communication device is an access network element, the second communication device is a user plane network element; or, if the first communication device is a user plane network element, the second communication device is an access network element.

[0143] The acquisition of parameter information by the...

Embodiment 2

[0170] The embodiment of this application provides a method for reporting user plane information, such as Figure 5 As shown, the method includes:

[0171] S501: The session management network element acquires parameter information, and the parameter information is used by the session management network element to instruct the first communication device to report user plane information when a reporting condition is met.

[0172] Wherein, if the first communication device is an access network element, the second communication device is a user plane network element; or, if the first communication device is a user plane network element, the second communication device is an access network element.

[0173] The acquisition of parameter information by the session management network element may include but not limited to the following three possible ways:

[0174] Method 1: The session management NE obtains parameter information according to the configuration policy. The configura...

Embodiment 3

[0197] In 5G, some traffic in the session can be diverted to the local router through diversion. One of the distribution methods is implemented by inserting a distribution point on the user plane path of the session. Specifically, the distribution point may be an uplink classifier (uplink classifier, ULCL) or a branching point (BP, Branching point). Such as Image 6 As shown, taking BP as an example, one session of UE has multiple anchor points, and this kind of session is called multi-homed session (multi-homed PDU session). For uplink service flow (upLink, UL), BP sends the received UL service flow to different anchor points according to forwarding rules; for downlink service flow (downlink, DL), BP sends DL service flow to UE according to forwarding rules.

[0198] The session management network element sends a seventh rule to the distribution point, where the seventh rule instructs the classification point to send the received user plane information to the local anchor p...

Abstract

The invention discloses a user plane information reporting method and device. The method comprises the steps that a session management network element obtains parameter information, and initiates thebuilding of a dedicated tunnel between a first communication device and a second communication device, wherein the parameter information is used for reporting user plane information when the session management network element indicates that the first communication device satisfies a reporting condition; the session management network element sends a first rule to the first communication device according to the parameter information, and the first rule is used for indicating the first communication device to send a message to the second communication device through the special tunnel when the reporting condition is met. By adopting the method, the session management network element can indicate the first communication device to send the message to the second communication device through thespecial tunnel when the first communication device meets the reporting condition through the first rule. Therefore, the second communication device can determine the report of the user plane information only by detecting whether to receive the message from the special tunnel, so that the logic function of the second communication device can be simplified.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for reporting user plane information. Background technique [0002] The rapid development of mobile communication has promoted the continuous emergence of various new services. In addition to traditional mobile broadband and the Internet of Things, mobile communication has also spawned many new application fields, such as augmented reality (augmented reality, AR), virtual reality ( virtual reality (VR), Internet of Vehicles, industrial control, Internet of things (IOT), etc. At the same time, higher requirements are placed on network bandwidth, delay and other performance, and the network load is further aggravated. [0003] In order to effectively meet the high-bandwidth and low-latency requirements required by the rapid development of the mobile Internet and the Internet of Things and reduce network load, the European Telecommunications ...
