A method of controlling a session related to a service

A control entity for controlling a session for providing a certain service, referred to as a “primary” control entity, in a communication network and comprising:

• a processor;
• and
• a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the primary control entity to performed acts comprising:
• obtaining a session control policy from a session control stream or generating such a policy as a function of a type of said service, which session control policy is to be implemented in the event of at least one data stream associated with the session being inactive;
• and
• sending the session control policy in a session control message to a control entity, referred to as a “secondary” control entity, which is in charge of implementing said session control policy.

A control entity, referred to as a “secondary” control entity, for controlling a session for providing a certain service in a communication network implementing session control signals, the secondary control entity comprising:

• a processor;
• and
• a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the secondary control entity to performed acts comprising:
• receiving a session control policy to be implemented in the event of at least one data stream associated with the session being inactive;
• and
• implementing said session control policy.

A system for controlling a session for providing a certain service in a communication network, the system comprising:

• a primary control entity comprising:
• a first processor;
• and
• a first non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the primary control entity to performed acts comprising:
• obtaining a session control policy from a session control stream or generating such a policy as a function of a type of said service, which session control policy is to be implemented in the event of at least one data stream associated with the session being inactive;
• and
• sending the session control policy in a session control message to a secondary control entity, which is in charge of implementing said session control policy;
• and
• the secondary control entity, which comprises:
• a second processor;
• and
• a second non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the secondary control entity to performed acts comprising:
• receiving from the primary control entity the session control policy to be implemented in the event of at least one data stream associated with the session being inactive;
• and
• on detecting inactivity of the at least one stream of the session for providing the certain service, implementing the session control policy received from the primary control entity for said session.

A non-transitory computer-readable data medium comprising program code instructions stored thereon for controlling a session for providing a certain service, when the instructions are executed by a processor of a primary control entity, at least one data stream being associated with said session, wherein the instructions configure the primary control entity to perform acts comprising:

• obtaining a session control policy from a session control message, or generating such a policy as a function of a type of said service, which session control policy is to be implemented in the event of at least one data stream associated with the session being inactive;
• sending said session control policy in a session control message to a control entity in charge of implementing said session control policy;
• and
• on detecting inactivity of the at least one data stream, implementing said session control policy.
