Abstract

A method and arrangement in a notification server (300) for controlling notifications with resource data to a subscribing client (A). When a subscription request is received (3:1) from the client for notifications with selected resource data of one or more resources, the access network currently used by the client is determined based on network related information, e.g. obtained from the received subscription request. The delivery of notifications (3:5) is then controlled based on the determined current network.

Claims

1. A method in a notification server for controlling notifications with resource data to a subscribing client, comprising:

receiving, by the notification server, a subscription request from the client for notifications with selected resource data of one or more resources;

determining, by the notification server, the access network currently used by the client, wherein the access network comprises a communications network and any one of a home network and a visited network;

selecting, by the notification server, a valid notification rule from two or more network depending notification rules stored in a database, wherein the database comprises a first column specifying a client, a second column specifying an access network, and a third column with one or more notification rules valid for a client and an access network, wherein the selected valid notification rule is valid for the client and the determined access network currently used by the client; and

controlling, by the notification server, the delivery of notifications with resource data to the client based on the determined current network, wherein the delivery of notifications is controlled by applying the selected valid notification rule, wherein said valid notification rule is defined by delivery of notifications not exceeding a maximum data amount and delivery of empty notifications devoid of resource data.

2. The method according to claim 1, wherein said network depending notification rules include one or more rules wherein no notifications are delivered if the client is roaming in a visited network, and all upcoming notifications are delivered if the client is present in his/her home network.

3. The method according to claim 1, wherein said notification rule is defined by using a delivery filter.

4. The method according to claim 3, wherein the delivery filter allows delivery of at least one of:

notifications with a certain type of resource data, notifications for one or more specific resources, and notifications at certain times of day, week or season.

5. The method according to claim 1, wherein different notification rules are applied depending on a time-out or TTL parameter in the subscription request.

6. The method according to claim 1, wherein the notification rule includes a rate limitation such that the frequency of notifications does not exceed a predefined limit.

7. The method according to claim 1, wherein the currently used network is determined based on network related information of the client obtained from any of:

said received subscription request, a publish message from the client, a third party registration request received from a session control node serving the client, and a SIP message from the client including INVITE, MESSAGE or OPTIONS.

8. The method according to claim 7, wherein the currently used network is determined from a PANI (P-Access-Network-Info) header in the subscription request, or from a P-Visited-Network-ID header in the registration request.

9. The method according to claim 7, wherein the network related information includes any of the parameters MNC (Mobile Network Code) and MCC (Mobile Country Code).

10. An arrangement in a notification server for controlling notifications with resource data to a subscribing client, comprising:

a resource data receiver implemented by the notification server to collect and store resource data in a database;

a subscription manager implemented by the notification server to;

receive a subscription request from the client for notifications with selected resource data of one or more resources;

determine the access network currently used by the client, wherein the access network comprises a communications network and any one of a home network and a visited network; and

select a valid notification rule from two or more network depending notification rules stored in a database, wherein the database comprises a first column specifying a client, a second column specifying an access network, and a third column with one or more notification rules valid for a client and an access network, wherein the selected valid notification rule is valid for the client and the determined access network currently used by the client; and

a notification sender implemented by the notification server to control the delivery of notifications with resource data to the client based on the determined current network by applying the selected valid notification rule, wherein said valid notification rule is defined by delivery of notifications not exceeding a maximum data amount and delivery of empty notifications devoid of resource data.

11. The arrangement according to claim 10, wherein the notification sender is further implemented by the notification server, based on one or more of said network depending notification rules, to deliver no notifications if the client is roaming in a visited network, and to deliver all upcoming notifications if the client is present in his/her home network.

12. The arrangement according to claim 10, wherein said notification rule is defined by using a delivery filter.

13. The arrangement according to claim 12, wherein the delivery filter allows delivery of at least one of:

notifications with a certain type of resource data, notifications for one or more specific resources, and notifications at certain times of day, week or season.

14. The arrangement according to claim 10, further implemented by the notification server to apply different notification rules depending on a time-out or TTL parameter in the subscription request.

15. The arrangement according to claim 10, wherein the notification rule includes a rate limitation such that the frequency of notifications does not exceed a predefined limit.

16. The arrangement according to claim 10, wherein the subscription manager is further implemented by the notification server to determine the currently used network based on network related information of the client obtained from any of:

said received subscription request, a publish message from the client, a third party registration request received from a session control node serving the client, and a SIP message from the client including INVITE, MESSAGE or OPTIONS.

17. The arrangement according to claim 16, wherein the subscription manager is further implemented by the notification server to determine the currently used network from a PANI (P-Access-Network-Info) header in the subscription request, or from a P-Visited-Network-ID header in the registration request.

18. The arrangement according to claim 16, wherein the network related information includes any of the parameters MNC (Mobile Network Code) and MCC (Mobile Country Code).
