Abstract
A policy and charging rules function (PCRF) device includes a memory storage comprising instructions, at least one network interface, and at least one processor coupled to the memory and to the at least one network interface. The instructions are executed by the at least one processor to receive a policy request of a first user sent by a gateway device; determine, according to the policy request, that the first user needs to use a counter of a second user; acquire a current status of the counter of the second user using a session of the second user established between the PCRF device and a charging system; and generate a control policy of the first user according to the current status of the counter of the second user and send the control policy to the gateway device.
Claims26
A policy and charging rules function (PCRF) device, comprising:
- a memory storage comprising instructions;
- at least one network interface;
- and
- at least one processor coupled to the memory and to the at least one network interface, wherein the instructions are executed by the at least one processor to:
- receive a policy request of a first user sent by a gateway device;
- determine, according to the policy request, that the first user needs to use a counter of a second user;
- acquire a current status of the counter of the second user using a session of the second user established between the PCRF device and a charging system;
- and
- generate a control policy of the first user according to the current status of the counter of the second user and send the control policy to the gateway device;
- with the determining, according to the policy request, that the first user needs to use the counter of the second user, comprising:
- acquire an identifier of the first user from the policy request;
- query stored information according to the identifier of the first user and determine that the first user is a member of a group and determine that an owner of the group is the second user;
- and
- determine that the first user and the second user share the usage quota, and that the first user needs to use the counter of the second user.
11 more elements
A policy decision method, comprising:
- maintaining, by a charging system, a counter of a second user;
- receiving, by the charging system, a session establishment request of the second user and sent by a policy and charging rules function (PCRF) device;
- establishing, by the charging system according to the session establishment request of the second user, a session of the second user established between the charging system and the PCRF device;
- receiving, by the charging system using the session of the second user, a counter status acquiring request requesting the counter of the second user, wherein a first user is a member of a group and an owner of the group is the second user, wherein the first user and the second user share a usage quota, and wherein the first user needs to use the counter of the second user;
- obtaining, by the charging system, a current status of the counter of the second user according to the counter status acquiring request;
- and
- returning, by the charging system, the current status of the counter of the second user to the PCRF device using the session of the second user, wherein the PCRF device determines the affected first user according to the current status of the counter of the second user, generates a control policy for the first user according to the current status of the counter of the second user, and sends the generated control policy to a gateway device using a session of the first user established between the gateway device and the PCRF device.
4 more elements
A charging device, comprising:
- a memory storage comprising instructions;
- at least one network interface;
- and
- at least one processor coupled to the memory and to the at least one network interface, wherein the instructions are executed by the at least one processor to:
- maintain a counter of a second user;
- receive a session establishment request of the second user sent by a policy and charging rules function (PCRF) device;
- establish, according to the session establishment request of the second user, a session of the second user established between the charging device and the PCRF device;
- receive, using the session of the second user, a counter status acquiring request requesting the counter of the second user, wherein a first user is a member of a group and an owner of the group is the second user, wherein the first user and the second user share a usage quota, and wherein the first user needs to use the counter of the second user;
- obtain a current status of the counter of the second user according to the counter status acquiring request;
- and
- return the current status of the counter of the second user to the PCRF device using the session of the second user, wherein the PCRF device determines the affected first user according to the current status of the counter of the second user, generates a control policy for the first user according to the current status of the counter of the second user, and sends the generated control policy to a gateway device using a session of the first user established between the gateway device and the PCRF device.
