Abstract
A subscription information processing method, a policy and charging control method, an online charging method, a visited network, a V-PCRF and a V-OCS, wherein, the subscription information processing method comprises: a visited network receiving visited network subscription information and account information of a roaming user, the visited network subscription information and the account information and home network subscription information and account information of the roaming user using the same user identification information; the visited network storing the visited network subscription information and the account information of the roaming user.
Claims20
A policy and charging control method, applied in a Local Break Out (LBO) roaming scenario, comprising:
- a visited network Policy and Charging Rules Function (V-PCRF) receiving an IP-Connectivity Access Network (IP-CAN) session establishment instruction message transmitted by a gateway of a visited network;
- when the V-PCRF determines according to the IP-CAN session establishment instruction message that a policy decision is made for an IP-CAN session of a roaming user through visited network subscription, the V-PCRF obtaining visited network subscription information of the roaming user from a visited network Subscription Profile Repository (V-SPR), and generating policy and charging control (PCC) rules according to the visited network subscription information;
- the V-PCRF sending the PCC rules to the gateway of the visited network.
An online charging method, applied in a Local Break Out (LBO) roaming scenario, comprising:
- a visited network Online Charging System (V-OCS) receiving a credit control request message transmitted by a gateway of a visited network;
- when the V-OCS determines according to the credit control request message that visited network credit control is directly performed for an IP-Connectivity Access Network (IP-CAN) session of a roaming user, obtaining visited network subscription information and associated account information of the roaming user from a V-OCS local database or an external database located in the visited network, and directly generating a visited network credit control policy according to the visited network subscription information and the associated account information;
- the V-OCS sending the visited network credit control policy to the gateway of the visited network.
A subscription information processing method, comprising:
- a visited network receiving visited network subscription information and account information of a roaming user, the visited network subscription information and the account information and home network subscription information and account information of the roaming user using the same user identification information;
- the visited network storing the visited network subscription information and the account information of the roaming user.
A visited network device, comprising:
- a receiving module, configured to receive visited network subscription information and account information of a roaming user, wherein the visited network subscription information and the account information and home network subscription information and account information of the roaming user use the same user identification information;
- a storing module, configured to store the visited network subscription information and the account information of the roaming user.
A visited network Policy and Charging Rules Function (V-PCRF), applied in a Local Break Out (LBO) roaming scenario, comprising:
- a receiving module, configured to receive an IP-Connectivity Access Network (IP-CAN) session establishment instruction message transmitted by a gateway of a visited network;
- a processing module, configured to, when determining according to the IP-CAN session establishment instruction message that a policy decision is made for an IP-CAN session of a roaming user through visited network subscription, obtain visited network subscription information of the roaming user from a visited network Subscription Profile Repository (V-SPR), and generate policy and charging control (PCC) rules according to the visited network subscription information;
- a sending module, configured to send the PCC rules to the gateway of the visited network.
A visited network Online Charging System (V-OCS), applied in a Local Break Out (LBO) roaming scenario, comprising:
- a receiving module, configured to receive a credit control request message transmitted by a gateway of a visited network;
- a processing module, configured to make a visited network credit decision according to the credit control request message, and generate a visited network credit control decision;
- a sending module, configured to send to the gateway of the visited network the visited network credit control decision;
- a subscription and account balance management module, configured to locally store and manage the visited network subscription information of a roaming user and visited network account information of the roaming user for the V-OCS;
- or used for the V-OCS to obtain from an external database located in the visited network or update the visited network subscription information and the visited network account information;
- wherein the visited network account information of the roaming user contains balance information used for visited network credit authorization.
