A method performed by performed by an exposure node having a first identity in a first network domain in a telecommunications network is provided. The method includes initiating a request towards a first network node for a subscription to an event of a communication device. The request includes subscription information for a common network exposure in at least two network domains. The method further includes receiving a response from the first network node. The response includes at least one of: a first confirmation that the event will be reported to the exposure node for a second network domain for the common network exposure and a second confirmation that the event will be reported to the exposure node for the first network domain. The second confirmation omits an indication of the common network exposure. Methods performed by a first network node are also provided.

Common event exposure in network domains

A method, performed by a first node (), for handling subscriptions in a communications network (). The first node () operates in the communications network (). The first node () sends (), to a second node (), a first indication. The first indication requests subscription to report new accessibility for a device () to a second domain different than a first domain currently accessible by the device (). The first node () receives () a second indication from the second node (). The second indication indicates the new accessibility by the device () to the second domain. A fifth node () receives (), from the first node (), a fifth indication indicating a notification of an event by the device () after the new accessibility has been enabled. The fifth indication is received based on a previous indication sent by the fifth node () prior to the new accessibility has been enabled.

Network nodes and methods performed thereby for handling subscriptions in a communications network

The invention relates to a method for operating a tracking entity () configured to track to which access and connectivity management entity () a mobile device () is connected in a mobile communications network, wherein an application server () is initiating a monitoring of an event occurring at the mobile device, the method comprising: —receiving a request to monitor the event at the mobile device (), the request comprising an indication for an audit for the monitoring of the event by which a validity of the monitoring of the event should be checked when the event has not been detected for an indicated period of time, —transmitting the received request for the event with the indication for the audit and the indicated period of time to the access and connectivity management entity () to which the mobile device is connected, —receiving a notification from the access and connectivity management entity () that the event has not been detected for the indicated period of time, —determining, in response to the received notification, based on information available in the tracking unit whether the monitoring of the event should be continued or not.

Audit process for the monitoring of events

A method for enabling a calling User Equipment, UE, to retry a Session Initiation Protocol, SIP, call attempt to a called UE, over a Circuit Switched domain, in a telecommunication network, wherein said called UE has a SIP session established towards said telecommunication network, wherein said method comprises the steps of receiving, by a Proxy Call Session Control Function, P-CSCF, node, an indication that a signalling bearer between said called UE and said telecommunication network is released, wherein said signalling bearer is associated with said SIP session, transmitting, by said P-CSCF node, to a Serving Call Session Control Function, S-CSCF, node triggered by said received indication, a subscribe message for informing said S-CSCF node that said P-CSCF unsubscribes to registration events pertaining to said called UE due to the released signalling bearer such that said S-CSCF node is able to initiate a CS retry when said telecommunication network receives a SIP call attempt from said calling UE to said called UE.

Method for enabling a calling User Equipment, UE, to retry a Session Initiation Protocol, SIP, call attempt to a called UE, over a Circuit Switched domain

The present invention concern methods and apparatuses for handling public identities in an Internet Protocol Multimedia Subsystem, IMS, network. A CSCF node receives information indicating a set of distinct public identities, within a range of a wildcarded public identity, which set of distinct public identities are not in the same Implicit Registration Set (IRS) as the wildcarded public identity. The information is received from a Home Subscriber Server (HSS) node. The CSCF node stores the information indicating the set of distinct public identities, which are not in the same IRS, in the CSCF node for allowing matching of an originating request to the information indicating the set of distinct public identities, which are not in the same IRS. Alternatively, the CSCF node forwards the information indicating the set of distinct public identities, which are not in the same IRS, to another CSCF node, for allowing matching of an originating request to the information indicating the set of distinct public identities, which are not in the same IRS.

Methods and apparatuses for handling public identities in an internet protocol multimedia subsystem network

A home subscriber server (HSS) and method are described herein for supporting an emergency telecommunication service (e.g., Government Emergency Telecommunications Service (GETS)). In one embodiment, the HSS and the method are adapted to selectively provide telecommunication access to subscribers of an IP Multimedia Subsystem (IMS) by associating different user priority values with different network condition statuses, where a network condition status may be a congestion level or a disaster relief emergency status.
