Problems solved by technology

If the 5G air interface rate increases to tens of Gbps, the traffic demand of the CPRI interface will rise to the Tbps level, which will bring huge pressure on the cost and difficulty of network deployment

Embodiment 1

[0122] Figure 6 It is a flow chart of generating and sending slice public configuration information according to an embodiment of the present invention. Among them, the CU generates the configuration information of one or more slices in units of slices, and sends them to the DU through the fronthaul interface. The DU centrally manages and schedules one or more slices according to the slice configuration information, so as to realize the isolation between slices and avoid Jane's interference, the specific steps are described as follows:

[0123] Step 601: adding or deleting or updating a slice triggers the CU to generate slice configuration information.

[0124] The configuration information includes at least one of the following: a mapping relationship between slices and physical resources or resource pools, slice priorities, slice quality of service QoS levels, slice maximum transmission rates, and slice resource occupation percentages. .

[0125] The trigger condition fo...

Embodiment 2

[0146] Figure 7 It is a schematic diagram of a flow for sending slice configuration information requested by a DU in an embodiment of the present invention. Among them, embodiment 2 is similar to embodiment 1, and it is also a slice public configuration information flow, the difference is that the transmission of slice configuration information is triggered by a DU request to a CU, and the specific steps are described as follows:

[0147] Step 701: adding or deleting or updating a slice triggers the CU to generate slice configuration information.

[0148] The slice configuration information includes at least one of the following: a mapping relationship between slices and physical resources or resource pools, slice priorities, slice quality of service (QoS) levels, slice maximum transmission rates, and slice resource percentages.

[0149] The trigger condition for generating the slice configuration information includes: addition, deletion, or update of slices.

[0150] The m...

Embodiment 3

[0169] Figure 8 It is a schematic flow diagram of generating and / or sending user-specific configuration information triggered by RB and / or LCH establishment, deletion, re-establishment, and slice change of user RB and / or LCH in the embodiment of the present invention. Among them, one or more user-specific configuration information is generated on a user-by-user basis and sent to the DU through the fronthaul interface. The DU performs centralized management and scheduling on one or more users according to the user-specific configuration information. The specific steps are described as follows:

[0170] Step 801: The user generates RB and / or LCH establishment, deletion, reconstruction, and the slice to which the user RB and / or LCH belongs changes, generates user-specific configuration information, and triggers the CU to send the configuration information to the DU.

[0171] The configuration information includes at least one of the following: a mapping relationship between a sl...

Abstract

The invention discloses a network slice management method and apparatus. The method comprises the following steps: a first network element receives slice configuration information sent by a second network element; and the first network element performs scheduling management on slices on an access network side according to the slice configuration information.

Description

technical field [0001] The present invention relates to the technical field of wireless communication systems, in particular to a method and device for managing network slices. Background technique [0002] In the fifth generation of mobile communication (5G, Fifth Generation), mass connections and higher rate requirements of users require long-term evolution (LTE, Long Term Evolution) in remote radio units (BBU, Remote Radio Unit) and baseband processing units ( The transmission capacity of the fronthaul interface between RRU (Building Baseband Unit)—Common Public Radio Interface (CPRI, Common Public Radio Interface) poses a great challenge, because the CPRI interface transmits the IQ after processing such as physical layer coding and modulation For signals, the CPRI interface has relatively large requirements on transmission delay and bandwidth. If the 5G air interface rate increases to tens of Gbps, the traffic demand of the CPRI interface will rise to the Tbps level, wh...
