Abstract

A method for paging admission control for multi-service flows in a mobile packet domain is provided and comprises steps of when authentication of a mobile station accessing a connectivity service network through an access service network succeeds, assigning a service flow paging strategy for a downlink service flow of the mobile station, and sending the service flow paging strategy to the access service network; receiving, by the access service network, downlink data of a mobile station in IDLE state from a home agent, searching for a downlink service flow to which the downlink data belong, and judging whether the service flow admits paging according to the service flow paging strategy, and if yes, initiating a paging flow triggered by the downlink data.

Claims

1. A method for paging admission control for multi-service flows in a mobile packet domain, comprising:

when authentication of a mobile station accessing a connectivity service network through an access service network succeeds, assigning a service flow paging strategy for a downlink service flow of the mobile station, and sending the service flow paging strategy to the access service network; and

receiving, by the access service network, downlink data of a mobile station in IDLE state from a home agent, searching for a downlink service flow to which the downlink data belong, and judging whether the service flow admits paging according to the service flow paging strategy, and if yes, initiating a paging flow triggered by the downlink data.

2. The method of claim 1, wherein the method specifically comprises:

when authentication of a mobile station accessing a connectivity service network through an access service network succeeds, assigning, by an authentication authorization accounting or strategy server, a service flow paging strategy for all downlink service flows of the mobile station, and sending the service flow paging strategy to the access service network for storage;

during establishment of service flows, utilizing, by an anchor service flow authorization functional entity situated in the access service network, the service flow paging strategy to obtain paging admission information of each service flow, and binding, by a serving service flow authorization functional entity, the service flow with the paging admission information thereof; and

after receiving, by an anchor data path situated in the access service network, downlink data of a mobile station in IDLE state from a home agent, searching for a downlink service flow to which the downlink data belong, and judging whether the service flow admits paging according to the paging admission information, and if yes, initiating a paging flow triggered by the downlink data.

3. The method of claim 1, wherein the service flow paging strategy adopts any one of the following approaches:

specifying a range of IP addresses in which paging is admitted;

or

explicitly pointing out whether each service flow admits paging or not.

4. The method of claim 2, wherein,

after the access service network receives the service flow paging strategy, the service flow paging strategy is stored by the anchor service flow authorization functional entity.

5. The method of claim 2, wherein the service flow establishment process further comprises:

A, during establishment of a service flow for the mobile station, searching, by the anchor service flow authorization functional entity, for the service flow paging strategy of the mobile station according to an identification of the service flow to obtain paging admission information of the service flow, the paging admission information indicating whether the service flow admits paging or not; and

B, sending, by the anchor service flow authorization functional entity, a resource reservation request to the anchor data path to trigger a flow of establishing a service flow path, wherein the paging admission information of the service flow is carried, and binding, by the anchor data path, the service flow with the paging admission information thereof after receiving the request.

6. The method of claim 5, further comprising:

in the step B, adding a new field of Type Length Value in the resource reservation request, or amending an original definition of a Type Length Value field in the resource reservation request, in order that the field is used to represent the paging admission information of the service flow.

7. The method of claim 5, wherein,

in the step B, the service flow bound with the paging admission information is uniquely determined by an identification of the mobile station, to which the service flow belongs, in conjunction with the identification of the service flow.

8. The method of claim 5, wherein,

in the step B, if the anchor service flow authorization functional entity and the anchor data path are deployed in one network element, the resource reservation request does not need to be transmitted between network elements, but is represented by an internal message, or sending of the resource reservation request is omitted.

9. The method of claim 2, wherein,

after receiving downlink data of the mobile station in IDLE state from the home agent, the anchor data path situated in the access service network finds the service flow to which the downlink data belong through searching a classifier, and then finds the paging admission information bound with the service flow by using an identification of the mobile station, to which the service flow belongs, in conjunction with an identification of the service flow.

10. The method of claim 2, wherein the service flow paging strategy adopts any one of the following approaches:

specifying a range of IP addresses in which paging is admitted;

or

explicitly pointing out whether each service flow admits paging or not.

11. The method of claim 7, wherein,

after receiving downlink data of the mobile station in IDLE state from the home agent, the anchor data path situated in the access service network finds the service flow to which the downlink data belong through searching a classifier, and then finds the paging admission information bound with the service flow by using an identification of the mobile station, to which the service flow belongs, in conjunction with an identification of the service flow.
