Problems solved by technology

[0003] However, the current quality of service (QoS, Quality of Service) and Evolved Packet System (EPS, Evolved Packet System) bearer strategy of the core network cannot guarantee the delay requirement of ultra-real-time service flow below 50 milliseconds (ms), and the Resource allocation based on terminal sessions will cause a certain delay in negotiation signaling
In addition, the current core network only adopts scheduling strategy, queue management strategy and rate shaping strategy for QoS delay guarantee, and does not involve resource reservation for QoS delay guarantee

Embodiment 1

[0131] This embodiment describes a static bearer reservation scenario under a non-SDN architecture. This scenario is mainly aimed at multiple terminals (UEs) under the non-SDN architecture that have the same type of ultra-real-time service flow data transmission requirements of less than 50ms, and this ultra-real-time service flow is a service flow with relatively small bandwidth requirements. Typical applications It is a sudden emergency business flow. The network topology in this scenario is as follows: Figure 10 As shown, UE1 and UE2 have the requirement of sending the same type of service flow (corresponding to Content1) to an application function (AF, Application Function) server.

[0132] In this embodiment, the content1 registration and resource reservation process of UE1 is as follows Figure 11 shown. Specifically, UE1 first sends a registration request (Flow Register (Content1)) to the base station (eNB) for Content1, and the eNB forwards the registration request...

Embodiment 2

[0136] This embodiment describes a dynamic bearer reservation scenario under a non-SDN architecture. This scenario is mainly aimed at multiple terminals (UEs) in a non-SDN architecture that have the same type of ultra-real-time service flow data transmission requirements of less than 50ms, and this ultra-real-time service flow is a service flow with relatively large bandwidth requirements. Typical applications For telemedicine scenarios, the network topology of this scenario is as follows Figure 14 As shown, UE1 and UE2 have the requirement of sending the same type of service flow (corresponding to Content2) to the AF server.

[0137] In this embodiment, the content2 registration and resource reservation process of UE1 is as follows Figure 15 shown. UE1 first sends a registration request (Flow Register (Content2)) to eNB for Content2, and eNB forwards the registration request to MME to query the corresponding Content2; MME will first obtain the Subscription Profile templat...

Embodiment 3

[0142] This embodiment describes the static bearer reservation scenario under the SDN architecture. This scenario is mainly aimed at multiple terminals (UEs) under the SDN architecture that have the same type of ultra-real-time service flow data transmission requirements of less than 50ms, and this ultra-real-time service flow is a service flow with relatively small bandwidth requirements. Typical applications are For sudden emergency traffic, the network topology of this scenario is as follows: Figure 18As shown, UE1 and UE2 have the requirement of sending the same type of service flow (corresponding to Content1) to the AF server.

[0143] In this embodiment, the content1 registration and resource reservation process of UE1 is as follows Figure 19 shown. UE1 first sends a registration request (Flow Register (Content1)) to eNB for Content1, and eNB forwards the registration request to MME to query the corresponding Content1. MME will first obtain the Subscription Profile t...

Abstract

The present application discloses a data transmission control method and system. The method includes: the first control network element on the core network side receives a registration request carrying content information from a terminal, and inquires whether the content information of the terminal is Registered; when the first control network element finds that the content information of the terminal corresponds to a super-real-time service flow, and the content information of the terminal is not registered, the registration event of the content information of the terminal Notifying the second control network element, so that the second control network element performs reservation processing of dedicated bearer resources for the data transmission of the super real-time service flow corresponding to the content information of the terminal. Through this application, dedicated bearer resources can be reserved for the data of the super real-time service flow, and the reserved dedicated bearer can be used to realize the data transmission of the super real-time service flow, and the transmission delay requirement of the super real-time service flow below 50 ms can be guaranteed. In addition, the present application also provides a data transmission method and device.

Description

technical field [0001] The present application relates to the communication field, and in particular to a data transmission control method and system, and a data transmission method and device. Background technique [0002] At present, the resource allocation mode on the core network side adopts the terminal-based session mode, and resource allocation is for terminal sessions, and the end of a session indicates that the allocated resources will be taken back. Wherein, a traffic flow template (TFT, TrafficFlow Template) matching manner is adopted to allocate resources for the session. The existing resource allocation and data transmission processes of the core network are as follows: figure 1 shown. figure 1 The solid line in represents the data path (Data Path), and the dotted line represents the control path (Control Path). [0003] However, the current quality of service (QoS, Quality of Service) and Evolved Packet System (EPS, Evolved Packet System) bearer strategy of ...
