Problems solved by technology

[0004] The inventors found that the existing EPC virtualization scheme has the following two problems: (1) Since the functional granularity of the existing virtualized network elements still continues the traditional network element functions, each virtualized network element has multiple functions, For example, the virtualized MME network element has multiple functions such as access control, mobility management, session management, and routing selection, and the functions of the virtualized network element that need to be invoked in different links of the service process may be

Example Embodiment

[0029] Example one

[0030] The embodiment of the present invention provides a virtualized EPC system 30, such as image 3 As shown, it includes: a business chain template library 301, a network function resource pool 303, and a business chain template library manager 302.

[0031] Among them, the business chain template library 301 includes N business chain templates, each of the N business chain templates describes a business process, and the business process includes at least one business function point and at least one business function point for realizing the business The network function resource pool 303 includes a collection of L atomic network function entities 3032 and a scheduling server 3031. Each of the atomic network function entity sets 3032 in the L atomic network function entity sets 3032 is used to implement a network function. , And the network functions implemented by any two atomic network function entity sets 3032 in the L atomic network function entity sets 3...

Example Embodiment

[0056] Embodiment two

[0057] The embodiment of the present invention provides a service instantiation method, which is applied to the virtualized EPC system 30 provided in the first embodiment, such as Figure 4 As shown, the method includes:

[0058] S401. The service chain template library manager 302 receives a service request message, which carries the type of the requested service, and determines a service chain template matching the service from the service chain template library 301 according to the type of service.

[0059] S402. The dispatch server 3031 determines the atomic network function entity corresponding to the service chain template from the set of L atomic network function entities 3032, and instantiates the service according to the atomic network function entity.

[0060] Among them, the L atomic network function entity set 3032 may specifically include: access control function entity set, mobility management function entity set, session management function entity...

Abstract

The embodiment of this invention provides a virtualization EPC (Evolved Packet Core) system and a service instantiation method, can improve the definition of a service process and reduce the investment and maintenance cost. The system comprises a service chain template library, a network function resource pool and a service chain template library manager; the service chain template library comprises N service chain templates; each service chain template describes a service process; the service process comprises at least one service function point for realizing the service, and circulation relationships among the service functions; the network function resource pool comprises L atom network function entity sets and a dispatch service; each atom network function entity set is used for realizing a network function; the service chain template library manager is used for receiving service request information and determining the service chain template matched with the service; the dispatch server is used for determining the instantiation service of the atom network function entity of corresponding service chain template. The virtualization EPC system and the service instantiation method are applicable to the technical field of communication.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a virtualized Evolved Packet Core (EPC) system and a service instantiation method. Background technique [0002] At present, network virtualization technology has been introduced into EPC to overcome the complex system management and operation and maintenance defects of traditional EPC network element equipment due to its tightly coupled software and hardware characteristics. [0003] figure 1 Shown is a schematic diagram of the existing virtualized EPC deployment method, such as figure 1 As shown, the existing virtualization solution integrates the four main network elements of the EPC—Mobility Management Entity (English: Mobility Management Entity, abbreviated: MME) and Serving Gateway (English: Serving Gateway, abbreviated: SGW) through four data centers. ), packet data network gateway (English: PDN Gateway, abbreviated: PGW) and home subscriber server (English: Ho...
