Abstract
The present invention relates to the field of data transmission, and discloses a method and system for providing a service according to a policy, which are used to resolve a problem that policy information included in information transmitted by different NSEs and different AEs cannot be correctly understood and executed by using an existing M2M system architecture, which results in a data transmission error or transmission failure.
Claims14
A system for providing a service according to a policy, wherein the system is based on a machine-to-machine (M2M) system architecture, the system comprising:
- a common service entity (CSE) comprising,
- one common service function (CSF) module that comprises a policy enforcement (PE) module and a policy decision (PD) module, or
- at least two CSF modules one of which comprises a PE module and the other one of which comprises a PD module;
- wherein the PE module and the PD module are configured to communicate with another CSF module in the CSE and an application entity (AE), the PE module is configured to communicate with an underlying network service entity (NSE), and the PE module and the PD module are configured to communicate with each other;
- wherein the PE module is configured to:
- receive service request information that is sent by the AE or the NSE,
- translate policy information comprised in the received service request information to a language that can be supported by the PD module,
- send the translated policy information to the PD module,
- acquire a service policy that is determined by the PD module according to the policy information, and
- provide, according to the service policy, a service that is requested by the service request information;
- and
- wherein the PD module is configured to:
- receive the translated policy information that is sent by the PE module, and
- determine the service policy according to the policy information.
A method for providing a service according to a policy, wherein the method is applied to a system that is based on a machine-to-machine (M2M) system architecture, the system comprising a common service entity (CSE) comprising:
- one common service function (CSF) module that comprises a policy enforcement (PE) module and a policy decision (PD) module;
- or at least two CSF modules one of which comprises a PE module and the other one of which comprises a PD module, and wherein the PE module and the PD module are configured to communicate with another CSF module in the CSE and an application entity (AE), the PE module is configured to communicate with an underlying network service entity (NSE), and the PE module and the PD module are configured to communicate with each other, the method comprising:
- receiving, by the PE module, service request information that is sent by the AE or the NSE;
- translating, by the PE module, policy information comprised in the received service request information to a language that can be supported by the PD module, wherein the policy information refers to information that is needed by the PD module to determine a service policy;
- sending, by the PE module to the PD module, the policy information that is obtained through translation, so that the PD module can determine the service policy according to the policy information;
- and
- acquiring, by the PE module, the service policy that is determined by the PD module, and providing, according to the service policy, a service that is requested by the service request information.
