To control content delivery to plural clients of a mobile communication network, a network entity of the mobile communication network collects geo information of the plural clients and evaluates the collected geo information of the plural clients based on a rule to determine whether the content delivery is to be adapted. The network entity identifies a region for which the content delivery is to be adapted. The network entity selectively outputs a message to a controlling entity if it is determined that the content delivery is to be adapted. The controlling entity controls the content delivery in response to receiving the message, to adapt the content delivery for clients located in the identified region.

Methods and devices for content delivery control

To control content delivery to plural clients () of a mobile communication network (), a network entity () of the mobile communication network () collects geo information of the plural clients () and evaluates the collected geo information of the plural clients () based on a rule to determine whether the content delivery is to be adapted. The network entity () identifies a region for which the content delivery is to be adapted. The network entity () selectively outputs a message () to a controlling entity () if it is determined that the content delivery is to be adapted. The controlling entity () controls the content delivery in response to receiving the message (), to adapt the content delivery for clients located in the identified region.

A distribution server for geographically targeted message distribution to a client is used for providing an application service, in particular a vehicular traffic related application service, such as a Cooperative Intelligent Transport System (C-ITS) service. An interworking device connects, e.g., via a cellular network connection, to the distribution server. Further, the interworking device connects via an ad-hoc network connection to the client. On behalf of the client, the interworking device performs registration for the application service at the distribution server. On the basis of the registration, the interworking device forwards at least one message of the application service between the distribution server and the client.

Interworking for geographically targeted distribution of application service messages via ad-hoc network

A method provides a network service in a communication network covering a geographical area for a plurality of mobile clients. A mobile client (among the plurality of mobile clients) registers with the communication network. A geomessaging register identifies a service enabler based on registration information of the mobile client. The geomessaging register sends, to the identified service enabler, contact information of the mobile client. The service enabler sends, to the geomessaging register, contact information of the service enabler. The geomessaging register then sends, to the mobile client, the contact information of the service enabler. The mobile client is then connected to the service enabler for receiving the network service. Related network nodes participate in providing such services.

The invention relates to a method for generating a personalized content file for a user entity using a file repair request for identifying a user. The file repair request is initiated by generating a preliminary file that is transmitted to the user entity, the preliminary file containing a predetermined placeholder. The preliminary file is transmitted to the user entity, the user entity starting the file repair request. The personalized content file is generated by replacing the predetermined placeholder in the preliminary file by a personalized content.

A technique for managing an automatically established roaming agreement between two IMS networks () is described, wherein one IMS network () supports multiple proxy nodes () at the network edge towards the other IMS network (). A method embodiment of the technique is performed in an I-CSCF () of the first IMS network () and comprises the steps of receiving () a registration request of an UE () via a second IMS network (); sending () a roaming information request indicating the second IMS network () to a HSS () associated with the first IMS network (); receiving () from the HSS () a roaming information answer indicating information related to the roaming agreement, and forwarding (), based on the roaming information answer, the registration request to a second I-CSCF () of the first IMS network () managing the roaming agreement.

A technique for creating a resource in a cloud computing system is described. A method implementation of this technique comprises providing a plurality of predefined base resource descriptions, each base resource description defining a base resource in the cloud computing system and specifying one or more properties of the base resource, providing a plurality of predefined modifiers, each modifier being applicable to a resource in the cloud computing system to add, remove or change a property of the resource, wherein each modifier is associated with metrics information, and receiving a resource request indicating one or more desired properties for a target resource in the cloud computing system. In response to receipt of the resource request, a selection operation is performed to select a base resource description and one or more modifiers that are to be applied to the base resource corresponding to the selected base resource description to create the target resource in the cloud computing system, wherein the selection operation is based on the metrics information. In a next step, the selected base resource description is deployed to create the corresponding base resource in the cloud computing system, and application of the selected modifiers to the base resource in the cloud computing system is triggered to create the target resource.
