Abstract

Methods, apparatus and computer program products for binding information management. A method implemented at a policy control node in a wireless communication network comprises: obtaining information indicating a collocated deployment of a session management node and a binding support node (202); and inhibiting, in response to the information, a registration of binding information to the binding support node (204). A policy control node can know that a binding support node is collocated with a session management node, and no registration of binding information to the binding support node will be triggered for the policy control node.

First claim

What is claimed is:

1. A method implemented at a policy control node in a wireless communication network comprising:
transmitting Diameter related attribute information to a network repository node during a registration procedure of the policy control node to enable the network repository node to provide the Diameter related attribute information to a session management node during a discovery procedure for the policy control node initiated by the session management node, wherein the Diameter related attribute information comprises an identifier of a Diameter host and a Diameter realm for the policy control node.

2. The method according to claim 1 , further comprising:
obtaining information indicating a collocated deployment of the session management node and a binding support node; and
inhibiting, in response to the information, a registration of binding information to the binding support node.

3. The method according to claim 2 , wherein the obtaining the information indicating the collocated deployment of the session management node and the binding support node comprises:
receiving, from the session management node, the information in a session management policy association create request or a session management policy association modification request.

4. The method according to claim 2 , wherein the obtaining the information indicating the collocated deployment of the session management node and the binding support node comprises:
receiving, from the network repository node, the information during a discovery procedure for the network repository node.

5. A method implemented at a session management node in a wireless communication network comprising:
receiving Diameter related attribute information of a policy control node from a network repository node during a discovery procedure for the policy control node, the Diameter related attribute information obtained by the network repository node during a registration procedure of the policy control node, wherein the Diameter related attribute information comprises an identifier of a Diameter host and a Diameter realm for the policy control node.

6. The method according to claim 5 , further comprising:
transmitting, to the policy control node, information indicating a collocated deployment of the session management node and a binding support node.

7. The method according to claim 6 , wherein the information indicating the collocated deployment of the session management node and the binding support node is transmitted, to the policy control node, in a session management policy association create request or a session management policy association modification request.

8. A method implemented at a network repository node in a wireless communication network comprising:
receiving, from a policy control node, Diameter related attribute information of the policy control node during a registration procedure for the policy control node, wherein the Diameter related attribute information comprises an identifier of a Diameter host and a Diameter realm for the policy control node; and
transmitting the Diameter related attribute information to a session management node during a discovery procedure for the policy control node initiated by the session management node.

9. The method according to claim 8 , further comprising:
receiving, from a binding support node, information indicating a collocated deployment of the session management node and a binding support node during a registration procedure for the binding support node; and
transmitting, to the policy control node, the information during a discovery procedure for the policy control node.

10. A policy control node in a wireless communication network comprising:
one or more processors; and
one or more memories containing computer program codes which, when executed by said one or more processors, cause said policy control node to:
transmit Diameter related attribute information to a network repository node during a registration procedure of the policy control node to enable the network repository node to provide the Diameter related attribute information to a session management node during a discovery procedure for the policy control node initiated by the session management node, wherein the Diameter related attribute information comprises an identifier of a Diameter host and a Diameter realm for the policy control node.

11. A session management node in a wireless communication network comprising:
one or more processors; and
one or more memories containing computer program codes which, when executed by said one or more processors, cause said session management node to:
receive Diameter related attribute information of a policy control node from a network repository node during a discovery procedure for the policy control node, the Diameter related attribute information obtained by the network repository node during a registration procedure of the policy control node, wherein the Diameter related attribute information comprises an identifier of a Diameter host and a Diameter realm for the policy control node.

12. A network repository node in a wireless communication network comprising:
one or more processors; and
one or more memories containing computer program codes which, when executed by said one or more processors, cause said network repository node to:
receive, from a policy control node, Diameter related attribute information of the policy control node during a registration procedure for the policy control node, wherein the Diameter related attribute information comprises an identifier of a Diameter host and a Diameter realm for the policy control node; and
transmit the Diameter related attribute information to a session management node during a discovery procedure for the policy control node initiated by the session management node.
