Abstract: The present disclosure generally relates to wireless communication technology. More particularly, the present disclosure relates to a method for providing a pre-paid service in a cellular communication network. The present disclosure also relates to apparatus and computer program product adapted for the same purpose. According to one embodiment, a method for providing a pre-paid service in a cellular communication network includes the following steps carried out at a first node: sending to a second node a request for subscribing to an event where resources for one of a group of subscribers have run out; and in response to a message on occurrence of the event from the second node, sending to a terminal device using the resources a notification that the resources have run out, wherein the first node is a node for application function (AF), and the second node is a node for exposing network capabilities and events.

Abstract: A UE is assigned a first server for session control of the session. The first IMS node sends a request to a subscriber server associated with the UE. The request requests assistance data for selecting a second server to be assigned to the UE for the session control. The first IMS node selects a second server to be assigned to the UE for session control, based on the requested assistance data. The first IMS node sends an invitation to the selected second server. The invitation includes an indication indicating that the selected second server is selected to replace the first server. The indication triggers the selected second server, to indicate to the subscriber server to register the address of the selected second server in the subscriber server, to replace the first server in being assigned to the UE for the session control.

Abstract: The present disclosure provides a method for a first network element in a communication network to perform service subscriptions for a UE. The method includes: in response to receiving a request comprising service subscription information for the UE from a second network element serving the UE and assisting in the service, cross referencing the service subscription information for the UE in the request with stored service subscription information for the UE for consistency; and in response to being not consistent, initiating updating of service subscriptions for the UE in the second network element according to the stored service subscription information for the UE. Corresponding devices, computer readable storage medium, carrier, etc. are also provided.

Abstract: An authentication server (16) in a home network (18) of a wireless device (10) receives, from a network node (14), a request (20) for authentication data (22) based on which to authenticate the wireless device (10). The request (20) indicates a serving network (12) on which the authentication data (22) is to be based. The authentication server (16) checks whether or not the network node (14) is authorized to request authentication data (22) that is based on the indicated serving network (12).

Abstract: A wireless communication device, WCD, is associated with multiple Machine Type Communication (MTC) applications, each application corresponding to a respective MTC Service Provider (SP) network that identifies it using a corresponding “external identifier”. The involved MTC SP networks use the same common identifier to request a wireless communication network, WCN, used to access the WCD to undertake certain configuration actions with respect to the WCD. The WCD may belong to a group of WCDs, in which case the common identifier is an external group identifier. The WCN advantageously determines which MTC SP network is the “requesting provider” for a given requested configuration action, and it restricts the configuration action within the WCN to the requesting provider.

Abstract: A method, performed by a first node (111), for handling subscriptions in a communications network (100). The first node (111) operates in the communications network (100). The first node (111) sends (303), to a second node (112), a first indication. The first indication requests subscription to report new accessibility for a device (140) to a second domain different than a first domain currently accessible by the device (140). The first node (111) receives (304) a second indication from the second node (112). The second indication indicates the new accessibility by the device (140) to the second domain. A fifth node (115) receives (501), from the first node (111), a fifth indication indicating a notification of an event by the device (140) after the new accessibility has been enabled. The fifth indication is received based on a previous indication sent by the fifth node (115) prior to the new accessibility has been enabled.
