Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

It should be noted that, in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that, when the difference is not emphasized, the intended meaning is consistent.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.

Before explaining the embodiments of the present invention in detail, some related arts related to the embodiments of the present invention will be described.

Edge computing means that an open platform integrating network, computing, storage and application core capabilities is adopted on one side close to an object or a data source to provide nearest-end service nearby, so that the effects of reducing network transmission paths and network time delay are achieved.

In some scenarios, not only is low latency for the network desired, but network construction costs are also desired. Therefore, a base station and MEC co-platform system is proposed, i.e. related MEC equipment is deployed directly on the base station. One base station corresponds to one Mobile Edge Platform (MEP), and the coverage areas of the two are the same. The MEP can directly provide edge computing services (such as traffic forwarding, localized processing and other services) for the UE within the coverage of the base station, without passing through a core network, thereby reducing the network construction cost and reducing the network transmission delay.

However, the base station and MEC share the same platform, and the user plane function is not involved in the scenario

When a User Equipment (UE) moves out of the coverage of a base station, the deployment of a (user plane function, UPF) network element cannot ensure the continuity of an application service of the UE according to a conventional manner of performing UPF reselection by a Session Management Function (SMF) network element. Therefore, how to guarantee the continuity of the application service of the UE in the scenario that the base station and the MEC share a platform is a problem that needs to be solved at present.

The communication method provided by the embodiment of the invention can be suitable for a common platform system (hereinafter referred to as a common platform system) of a base station and an MEC, and the common platform system is used for ensuring the continuity of the UE edge computing service. Fig. 1 shows a schematic structure of the co-platform system. As shown in fig. 1, co-platform system 10 includes a serving MEP11, a serving base station 12, a target MEP13, a target base station 14, and a Mobile Edge Orchestrator (MEO) 15. The serving MEP11 is connected to the serving base station 12 and the MEO15, respectively, and the target MEP13 is connected to the target base station 14 and the MEO15, respectively.

It should be noted that, the connection between the serving MEP11 and the serving base station 12 and the connection between the target MEP13 and the target base station 14 are both connections under the MEC architecture. As shown in fig. 2, a schematic structural diagram of an MEC architecture is shown, which includes a wireless access network intelligent controller (RIC), a base station, an MEC data plane (MEC DP), an MEC host (MEC host), and a mobile edge orchestrator ((ME editor, MEO), where the MEC host is composed of an MEP, an MEC application (MEC APP), and an MEP manager (MEP manager).

The MEO is a core function of the MEC architecture, and macroscopically governs resources and capacity of the MEC network, including all the MEC hosts and services already deployed, available resources in each MEC host, base station information of each MEC host connection, applications already instantiated, topology of the network, and the like.

Fig. 3 is a flow diagram illustrating a method of communication, according to some example embodiments. In some embodiments, the above communication method may be applied to a co-platform system as shown in fig. 1.

In one design, as shown in fig. 3, the communication method provided in the embodiment of the present disclosure is applied to a common platform system of a base station and a mobile edge computing MEC, where the common platform system of the base station and the MEC includes a target mobile edge platform MEP, a service MEP currently providing an edge computing service for a UE to be switched, and a target base station to be accessed by the UE to be switched, and includes the following steps S201 to S202.

S201, the target MEP receives the switching information sent by the service MEP.

The switching information comprises a service routing rule of the UE to be switched; the switching information is used for indicating the target MEP to provide the edge computing service for the UE to be switched after the UE to be switched accesses the target base station.

As a possible implementation manner, the serving MEP sends the handover information to the target address through the preset interface, so that the handover information is successfully sent to the target MEP. Accordingly, the target MEP receives the handover information transmitted by the serving MEP.

It should be noted that the preset interface is set by the operation and maintenance staff in the service MEP, for example, the preset interface may be an MP3 interface on the service MEP.

S202, after the UE to be switched is accessed to the target base station, the target MEP provides edge calculation service for the UE to be switched according to the service routing rule and the bearing information of the target base station.

As a possible implementation manner, the target MEP communicates with the target base station according to the bearer information, and activates the responsive service routing rule through the MEC DP, so that the target MEP provides the edge computing service for the UE to be switched, which is accessed to the target base station.

In some embodiments, after the target MEP successfully provides the edge computing service for the UE to be switched, the target MEP sends an activation completion message to the serving MEP to indicate that the target MEP has activated the service routing rule of the UE to be switched, and successfully provides the edge computing service for the UE to be switched. And the service MEP stops the service routing rule of the UE to be switched after receiving the activation completion message sent by the target MEP.

The technical scheme provided by the embodiment of the invention at least has the following beneficial effects: according to the communication method provided by the invention, the target MEP can receive the switching information sent by the service MEP. Because the switching information includes the service routing rule of the UE to be switched, after the UE to be switched is accessed to the target base station, the target MEP can continue to provide the edge computing service for the UE to be switched according to the service routing rule and the bearing information of the target base station, thereby ensuring the continuity of the edge computing service of the UE to be switched.

In one design, as shown in fig. 4, the communication method provided in the embodiment of the present disclosure is applied to a common platform system of a base station and a mobile edge computing MEC, where the common platform system of the base station and the MEC includes a serving mobile edge platform MEP currently providing an edge computing service for a UE to be switched and a serving base station currently accessed by the UE to be switched, and includes the following steps S301 to S304.

S301, the service MEP determines that the UE to be switched exists in the coverage area of the service base station.

As a possible implementation manner, when the serving MEP receives a handover notification event message sent by the serving base station, the serving MEP determines that the UE to be handed over exists in the coverage area of the serving base station.

As another possible implementation manner, when the serving MEP receives an "end flag" sent by the serving base station through the RNIS, the serving MEP determines that the UE to be handed over exists in the coverage of the serving base station.

Note that, the "end flag" is used to indicate that the UE handover procedure is in progress and is set in the RNIS in advance for the operation and maintenance staff. The serving base station determines whether to transmit an "end flag" to the serving MEP based on the RNIS layer 2measurement information, i.e., through the utilization rate of PRBs. For example, when the PRB utilization of a certain UE is lower than a preset utilization threshold, the serving base station considers that the UE moves at the serving cell boundary, determines the UE as a UE to be handed over, and sends an "end mark" to the serving MEP.

S302, the service MEP determines a target base station to which the UE to be switched is to be accessed.

As a possible implementation manner, the serving MEP receives the context of the UE to be switched sent by the serving base station, and determines the target base station to which the UE to be switched is to access from the context of the UE to be switched.

Specifically, the serving MEP first obtains the signal strengths of a plurality of adjacent base stations measured by the UE to be handed over from the context; further, the serving MEP arranges the plurality of neighboring base stations in order of decreasing signal strength to obtain an arrangement result. The serving MEP determines the neighboring base station located first in the ranking result as the target base station, that is, the serving MEP determines one neighboring base station with the highest signal strength among the neighboring base stations as the target base station.

S303, the service MEP acquires a destination address of the destination MEP.

Wherein the target MEP is connected with the target base station.

As a possible implementation manner, the serving MEP determines the target address from a mapping relationship including a plurality of base station identifiers and a plurality of MEP addresses according to the identifier of the target base station.

It should be noted that the mapping relationship may be set in the service MEP by the operation and maintenance personnel in advance.

As another possible implementation, the serving MEP sends a query request with the target base station ID to the MEO through the serving MEPM. Further, the serving MEP receives a destination address of the destination MEP sent by the MEO.

Specifically, after receiving the query request with the target base station ID, the MEO determines the target MEP connected to the target base station by acquiring the RNIS in the target base station, and sends the target address of the target MEP to the serving MEP.

S304, the service MEP sends the switching information to the target MEP according to the target address.

The switching information comprises a service routing rule of the UE to be switched; the switching information is used for indicating the target MEP to provide the edge calculation service for the UE to be switched after the UE to be switched accesses the target base station.

As a possible implementation manner, the serving MEP sends the handover information to the target address through the preset interface, so that the handover information is successfully sent to the target MEP.

Accordingly, the target MEP receives the handover information transmitted by the serving MEP.

Fig. 5 is a flow diagram illustrating a method of communication, according to some example embodiments. In some embodiments, the above communication method may be applied to a co-platform system as shown in fig. 1.

As shown in fig. 5, the communication method provided in the embodiment of the present invention includes the following steps S401 to S409.

S401, the serving MEP subscribes UE switching notification events to the serving base station.

The service MEP provides the MEP of the edge computing service for the user equipment UE to be switched at present; the service base station is a base station to which the UE to be switched is currently accessed. The UE handover notification event is used for the serving base station to send a handover notification event message to the serving MEP when the UE to be handed over occurs within the coverage of the serving base station.

As a possible implementation, the serving MEP subscribes to the UE handover notification event through the RIC to the serving base station.

As another possible implementation, the serving MEP subscribes to a Radio Network Information Service (RNIS) including a UE handover notification event from the serving base station.

It should be noted that the RNIS can provide at least the following information: 1) the latest wireless network information of the serving base station. 2) The serving base station is based on user plane related measurement information of the third generation partnership project (3 GPP), for example, Layer 2(Layer 2measurements) measurement information for measuring Physical Resource Block (PRB) utilization. 3) The serving base station information and the information of the UE under the serving base station, such as the identity and cell number of the serving base station, the identity and context of each UE under the serving base station, and the like. 4) UE related information changes in the serving base station, such as UE handover.

S402, the service MEP determines that the UE to be switched exists in the coverage area of the service base station.

S403, the service MEP sends a context request of the UE to be switched to the service base station.

As a possible implementation, the serving MEP sends a context request of the UE to be handed over to the serving base station through the subscribed RNIS.

S404, the service base station sends the context of the UE to be switched to the service MEP.

As a possible implementation manner, after receiving the context request of the UE to be switched sent by the serving MEP, the serving base station sends the context of the UE to be switched to the serving MEP.

It should be noted that the context of the UE to be handed over includes all network information of the UE to be handed over under the serving base station. For example, an Identity (ID) of the UE to be handed off, and base station information related to the UE to be handed off (e.g., signal strength of each neighboring base station and base station ID). The ID of the UE to be switched may be a Temporary Mobile Subscriber Identity (TMSI), i.e. a temporary UE identifier in the 3GPP network. The base station ID (also called bearer ID) may be an Evolved Packet System (EPS) bearer ID in a 3GPP network, or may be an evolved radio access bearer (E-RAB) bearer ID.

Correspondingly, the serving MEP receives the context of the UE to be switched, which is sent by the serving base station.

S405, the serving MEP determines a target base station to which the UE to be switched is to be accessed.

S406, the service MEP acquires the target address of the target MEP.

Wherein the target MEP is connected with the target base station.

S407, the service MEP sends the switching information to the target MEP according to the target address.

S408, after the UE to be switched accesses the target base station, the target MEP acquires the bearing information of the target base station.

As a possible implementation manner, after the UE to be switched accesses the target base station, the target MEP sends a bearer information request to the target base station. Correspondingly, the target base station sends the bearer information to the target MEP.

It should be noted that the bearer information of the target base station includes an identifier of the target base station, an internet protocol address (IP) of the target base station, a port number of the target base station, an IP of the MEC DP, and a port number of the MEC DP.

In practical applications, the target MEP may obtain radio bearer resources of the target base station from the RNIS of the target base station.

S409, the target MEP provides edge calculation service for the UE to be switched according to the service routing rule and the bearing information of the target base station.
