摘要:
A data layered architecture (DLA) system includes a front end (FE) server and a common directory (CD). The FE server includes a processing unit which defines an FE time zone (FETZ) based on the FE server's geographical location and that defines a current date and time of the FETZ. The FE server includes a network interfacing unit which obtains from the CD through the network a subscriber default time zone (SDTZ), a subscriber service time zone (SSTZ), a service activation date (SAD) and a service activation time (SAT). The processing unit selects as service time zone (STZ) for executing the service the SSTZ, if a valid SSTZ exists, or the SDTZ, if a valid SSTZ does not exist, or the FETZ, if a valid SDTZ does not exist. Furthermore, the processing unit only executes the service after checking that the SAD and SAT of the STZ correspond to the current date and time of the FETZ.

There are services that can be invoked by the subscribers, or triggered by a network entity, and wherein this invocation or trigger may depend on date or time of the day, namely, time-dependent services. Regarding the execution of these time-dependent services, there might be two problems with the determination of the execution time. The first problem is caused by the nature of so called “Data Layered Architectures” where the service execution servers, referred to as “Front-Ends” and the database servers storing the subscriber data, referred to as “Common Directory” are geographically spread over different time zones. As a consequence, the “Front-End” executes the service according to its own time zone rather than at the time zone where the subscriber is currently located or at home. The second problem is cause by the subscriber when he is roaming in an area located in a different time zone than his home time zone. For example a Subscriber has configured a Call Forwarding Unconditional Service with a time range everyday so that all calls received in that period of time are diverted to a voice mailbox, e.g. from 19:00 to 07:00 all received calls are forwarded to the voice mailbox. Let's imagine that the Subscriber moves to a visited network some time zones away from his/her original one, for example the period of time 19:00 to 07:00 in the original time zone corresponds to 14:00 to 02:00 in the new time zone. It means that the Subscriber stops receiving call at 14:00, so an important call might be diverted to voice mailbox. But also the Subscriber begins receiving calls at 02:00, when s/he is still sleeping. So the experience is a bit annoying. The problem is solved in that a Front-Ends server executing the Service might recalculate the service (execution) time with the applicable time zone. The applicable time zone is selected from the time zone where the Subscriber is located, SLTZ, the time zone of the Server executing the service, FETZ, or the time zone of the stored service date and time, SSTZ or SDTZ.

Method, apparatuses and computer programs for handling data related to users of a communications system comprising: a database server storing data related to users of the system, and a plurality of service servers. The database server modifies (1103) a first data stored therein for a user according to a received request (1101), and sends a second message (1109) notifying the data modification to a first service server comprising: an identifier of the user, the first data after the modification, and an identifier of a second service server of the system that handle data related to the user. The first service server sends a third message (2105) to the second service server requesting to modify a data held therein in relationship with said user. Features of the invention help in reducing signaling in layered systems, since additional data are communicated in the second message.
摘要:
The invention related to handling core network entities of a radio core communications network comprising a first network entity and a second network entity. The said second network entity differs from the first network entity in that it is capable of processing interworking between messages exchanged with said radio core communications network and messages exchanged with an IP multimedia subsystem. In other words, one network entity is capable of performing inter-working while the other one not. The first and/or second network entities are provided (S200) with configuration information indicating a relationship between the two network entities. The invention then foreseen routing (S300) messages relating to calls established between the at least one user terminal attached to the entity non capable of inter-working and a further user terminal attached to said IP multimedia subsystem according to said configuration information.

摘要:
The present invention is aimed to provide means and methods for recovery of an IP Multimedia Subsystem ‘IMS’ where a Home Subscriber Server ‘HSS’ holding subscriber data for subscribers of the IMS has suffered a restart. A first method of recovery is applied after detecting a HSS restart, and as receiving a registration from a given subscriber or an invitation to communicate with a given subscriber from another subscriber. A second method of recovery is applied after detecting a HSS restart, and as receiving a request from a given subscriber at a S-CSCF previously assigned for serving the given subscriber in the IMS. Both first and second methods may be applied in the IMS separately, or in cooperation, following a best effort to ensure that, whatever event occurs first, receiving a registration from a given subscriber, or an invitation to communicate with a given subscriber, or receiving a request from a given subscriber at a S-CSCF previously assigned, the actions triggered by the first method or by the second method achieve the recovery of the IMS without further actions not applied yet from said second or first methods.
