Method for service implementation in network function virtualization (nfv) system and communications unit

A virtualized infrastructure manager (VIM) comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• receive a route and resource configuration request message from a network function virtualization orchestrator (NFVO), wherein the route and resource configuration request message includes service chain template information, and the service chain template information corresponds to a service route and indicates a relationship between a service chain identifier and information about service chain;
• and
• perform, according to the service chain template information, route and resource configuration for a virtualized network function (VNF) of a service chain in the service chain template.

A network function virtualization orchestrator (NFVO) comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• receive service chain template information from an operations support system (OSS), wherein the service chain template information corresponds to a service route and indicates a relationship between a service chain identifier and information about service chain;
• and
• send a route and resource configuration request message to a virtualized infrastructure manager (VIM) for route and resource configuration for a virtualized network function (VNF) of a service chain in the service chain template, wherein the route and resource configuration request message includes the service chain template information.

An operations support system (OSS), comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• send service chain template information to a network function virtualization orchestrator (NFVO), wherein the service chain template information corresponds to a service route and indicates a relationship between a service chain identifier and information about service chain;
• wherein the NFVO can be triggered by the service chain template information to perform a route and resource configuration for a virtualized network function (VNF) of a service chain in the service chain template.
