Abstract

There is disclosed a method of providing subscription services, the method comprising: establishing a subscription dialog to activate a subscription; terminating said subscription dialog upon establishment of said subscription; and establishing a notification to a subscriber by the steps of: determining the location of the subscriber; establishing a notification dialog to notify the located subscriber; and terminating said notification dialog upon completion of the notification.

Claims

1. A method, comprising:

establishing a subscription dialog to activate a subscription;

terminating said subscription dialog and releasing resources for the subscription dialog upon establishment of said subscription such that the subscription is maintained after releasing the resources for the subscription dialog; and

in response to establishing the subscription for a subscriber establishing a notification to the subscriber,

wherein the establishing the notification comprises

determining a location of the subscriber,

establishing a notification dialog to notify the located subscriber, and

terminating said notification dialog upon completion of the notification,

where establishing said subscription dialog comprises providing a filter criteria in said subscription dialog,

where said filter criteria is configured to include an instruction for a network element to selectively record a subscription route at the network element, and wherein the network element comprises a serving call state or session control function associated with a server providing a subscribed service.

2. A method according to claim 1, wherein the establishing the subscription dialog and the establishing the notification dialog each comprise using session initiation protocol sessions.

3. A method according to claim 1, further comprising:

storing a subscription identifier on establishing said subscription.

4. A method according to claim 1, wherein the establishing the notification to the subscriber is responsive to an occurrence of a subscribed event.

5. A method according to claim 3, wherein the determining the location of the subscriber comprises sending the subscription identifier to a location services function.

6. A method according to claim 1, wherein the providing comprises providing said filter criteria comprising a subscriber filter criteria,

the method further comprising:

providing a system filter criteria to the network element,

wherein, when the system filter criteria matches the subscriber filter criteria, a combination of both filter criteria is applied.

7. A method according to claim 6, further comprising:

overriding the subscriber filter criteria with the system filter criteria.

8. A method according to claim 6, further comprising:

overriding the system filter criteria with the subscriber filter criteria.

9. A method according to claim 4, wherein the determining the location of the subscriber comprises sending the subscription identifier to a location services function.
