Apparatus and method for managing quality of service in integrated network of heterogeneous mobile network

A method for managing quality of service (QoS) in an integrated network system, comprising:

• receiving a user profile request signal at a policy and home subscriber server (PHSS) from a local network manager (LNM);
• providing, from the PHSS to a profile manager (PM), a user profile in accordance with the user profile request signal;
• transferring the user profile from the PM to a conditioner;
• checking, at the conditioner, whether or not a user subscribes to a related service in accordance with the user profile;
• sending network information from a network monitor to the conditioner;
• calculating, at the conditioner, conditions that are used for selecting a policy based on the user profile and the network information when the conditioner determines that the related service is subscribed to by the user;
• transmitting the calculated conditions from the conditioner to a ruler;
• deciding, at the ruler, on a network equipment control algorithm based on the calculated conditions;
• forwarding, from the ruler to the PHSS, a policy information request signal for policy information corresponding to the decided network equipment control algorithm;
• receiving, at the ruler from the PHSS, the policy information in accordance with the policy information request signal;
• acquiring, at a global resource manager (GRM) from the ruler, a request resource allocation message in accordance with the received policy information;
• and
• allocating resources, using the GRM, in accordance with the forwarded request resource allocation message from the ruler.

A non-transitory computer readable recording medium for managing quality of service (QoS) in an integrated network system, the computer readable recording medium having coded computer instructions comprising:

• receiving a user profile request signal at a policy and home subscriber server (PHSS) from a local network manager (LNM);
• providing, from the PHSS to a profile manager (PM), a user profile in accordance with the user profile request signal;
• transferring the user profile from the PM to a conditioner;
• checking, at the conditioner, whether or not a user subscribes to a related service in accordance to the user profile;
• sending network information from a network monitor to the conditioner;
• calculating, at the conditioner, conditions that are used for selecting a policy based on the user profile and the network information when the conditioner determines that the related service is subscribed to by the user;
• transmitting the calculated conditions from the conditioner to a ruler;
• deciding, at the ruler, on a network equipment control algorithm based on the calculated conditions;
• forwarding, from the ruler to the PHSS, a policy information request signal for policy information corresponding to the decided network equipment control algorithm;
• receiving, at the ruler from the PHSS, the policy information in accordance with the policy information request signal;
• acquiring, at a global resource manager (GRM) from the ruler, a request resource allocation message in accordance with the received policy information;
• and
• allocating resources using the GRM in accordance with the forwarded request resource allocation message from the ruler.
