The invention provides a solution to accessing for a geographical location information-based service in a server of a machine type communication based communication system, where firstly a server broadcasts or multicasts a content request message, the content request message comprising information on requested content and information on a target geographical location; then the server receives a response message from at least one user equipment, the response message indicating that the at least one user equipment possesses the requested content and the at least one user equipment being located within the target geographical location; and finally the server acquires the requested content from the at least one user equipment.

A global endpoint may be associated with an organization name and a plurality of directories located in different geographic regions. The global endpoint may be a computing system that hosts a page used by users to access an application or service. A user may be able to access the application or service using already existing credentials. For example, the user may access the application or service using credentials stored and maintained by an entity with which the user is affiliated. Users having credentials stored in different geographic regions may be able to access the application or service via the same global endpoint.

A method of and a device for operating a service discovery and selection function in a telecommunications system, wherein the service discovery and selection function registers a service profile of a service provided by at least one service producer of the telecommunications system. The service profile among others includes consistency group information and proximity information. The consistency group information identifies instances of the service sharing a same state and the proximity information identifies deployment of the instances in the telecommunications system. The service discovery and selection function, from the service profile, based on service selection criteria, selects a single service instance of the service for a service consumer of the telecommunications system requesting the service, and identifies the selected service instance to the service consumer.

The present invention faces the issues of re-selection of another NF Service instance (103, 201) for a subsequent request (S-520, S-535) with a same data consistency (Consistency 1) as a previously selected NF Service instance (101). To solve this issue, the present invention provides for identifying at configuration, based on the deployment and on the Storage solution for the Session/context data, which instances (101, 103, 201) of the same service type have access with strong consistency to the same data, and provide this information to the consumer (40), so it is allowed to prioritize selection of an alternative NF service instance that supports strong consistency, whenever possible.

Systems and methods for resolving names in a data network. A data network includes an information-centric network layer, ICN-layer, with multiple routers, and a name resolution layer with multiple name resolvers. Each router receives an interest packet announcement describing data objects provided by a data producer. Each router determines a first name resolver of the name resolution layer closest to the data producer and sends a name of the provided data object and geo-location of the data producer to the first name resolver. The first name resolver transmits the name of the data object and geo-location of the data producer to other name resolvers. Each router receives an interest packet request describing a data object requested by a data consumer. Each router transmits the interest packet request to a second name resolver spatially closest to the data consumer. Each name resolver provides the geo-location of the requested data object to the data consumer.

A method for communication session management by a session controller is described. Usage data associated with a video communication session is received for data stream handlers of a first network topology, which handle data streams of the video communication session at a first time. The first network topology includes a plurality of client devices and at least a first media server. A second network topology is determined based on the usage data to handle the data streams when a network parameter and/or an application parameter reaches a corresponding update threshold. Data stream handlers of the second network topology include at least a second media server. The data stream handlers of the second network topology are configured to handle the data streams at a second time, including instructing the first media server to offload at least some of the data streams to the second media server.

A method for operating a distributed application includes: transmitting, by an application frontend, an initialization request to a registration server via a communication network; selecting, by the registration server, an instance of an application backend and transmitting a fully qualified domain name of the selected instance to the application frontend; transmitting, by the application frontend, a lookup request to a domain name server; transmitting, by the domain name server, an IP address associated with the fully qualified domain name to the application frontend; transmitting, by the application frontend, application data to the transmitted IP address via a connection provided by the communication network; selecting, by a core server of the communication network, a quality service for the distributed application; applying, by the communication network, a service quality determined by the selected quality service to the connection; and operating, by the distributed application, with the applied service quality.

A method for operating a distributed application includes: transmitting, by an application frontend, upon a launch of the application frontend, a lookup request based on a predetermined fully qualified domain name associated with an application backend to a domain name server via a communication network; transmitting, by the domain name server, upon receipt of the fully qualified domain name, an IP address associated with the fully qualified domain name to the application frontend; transmitting, by the application frontend, upon receipt of the IP address, application data to the transmitted IP address via a connection provided by the communication network; selecting, by a core server of the communication network, upon transmission of the application data, a quality service for the distributed application; applying, by the communication network, a service quality determined by the selected quality service to the connection; and operating the distributed application with the applied service quality.
