The invention relates to a method for providing roaming services, for a user equipment, within a mobile communication network, the mobile communication network comprising a core network and an access network, the access network of the mobile communication network comprising at least one radio cell being served by a base station entity, wherein the user equipment is able to be attached to the mobile communication network via the base station entity despite the user equipment being related to a further mobile communication network as the home public land mobile network of the user equipment, wherein the core network comprises a serving core network node and a home subscriber server functionality, wherein the serving core network node provides mobility management functionality regarding the base station entity and thereby provides mobility management functionality regarding the user equipment, wherein the further mobile communication network comprises a further core network, the further core network comprising a further home subscriber server functionality, the further home subscriber server functionality being able to provide subscription profile data regarding the user equipment, wherein upon attachment of the user equipment with the mobile communication network the method comprises the following steps: in a first step, the serving core network node requests, from the home subscriber server functionality and by means of a first request message, subscription profile data regarding the user equipment, in a second step, subsequent to the first step, the home subscriber server functionality requests, from the further home subscriber server functionality and by means of a second request message, subscription profile data regarding the user equipment, in a third step, subsequent to the second step, the further home subscriber server functionality transmits, by means of a first response message, first subscription profile data regarding the user equipment to the home subscriber server functionality, in a fourth step, subsequent to the third step, the home subscriber server functionality transmits, by means of a second response message, second subscription profile data to the serving core network node having requested subscription profile data by means of the first request message, the second subscription profile data corresponding at least in part to the first subscription profile data.

Provision of subscriber profile to a MME in case of roaming

A method for extending IP Multimedia Subsystem (IMS)-oriented handling of telecommunications services within a telecommunications network for a subscriber using circuit switched (CS) connectivity, wherein an identification information of the subscriber is natively lacking an IMS identity and/or IMS profile within the telecommunications network, includes: generating, at least temporarily, by an identity management functionality of the telecommunications network, an IMS identity and/or IMS profile with respect to the subscriber.

Method and apparatus for extending the use of an IMS oriented handling of telecommunications services

A method for indicating routing capacity related data or routing delay related data via signalling messages in a core network of a telecommunications network using Diameter messages of a Diameter protocol includes: transmitting a first piece of routing capacity related information from a first Diameter enabled network node to a second Diameter enabled network node, and transmitting a second piece of routing capacity related information from the first Diameter enabled network node to the second Diameter enabled network node. The first and second pieces of routing capacity related information are transmitted by at least one Diameter message, wherein the first piece of routing capacity related information comprises aggregated routing capacity data or aggregated routing delay data related to a first routing alternative, and the second piece of routing capacity related information comprises aggregated routing capacity data or aggregated routing delay data related to a second routing alternative.

Indicating routing capacity related data or routing delay related data via signalling messages in a core network of a telecommunications network using diameter messages

A method for saving energy in operating first and second mobile communication networks by invoking an energy saving operational mode of the first and second mobile communication networks includes: operating a first radio access network in a first operational mode for peak time usage of the first mobile communication network, and in a second operational mode for off-peak time usage of the first mobile communication network; and invoking, at least partly during off-peak time usage of the first and second mobile communication networks, the energy saving operational mode of the combination of the first and second mobile communication networks such that the first radio access network is operated in the second operational mode while the second radio access network is operated such that coverage and capacity requirements in a geographic area are ensured by the combination of the first and second mobile communication networks.

A Core Network for data transmission in an Evolved Packet System (EPS) includes: one or more node(s) serving as a Home Location Register (HLR) according to a GSM/UMTS mobile communication network standard; a node serving as a Home Subscriber Server (HSS) according to 3GPP standards; and an Interworking Function (IWF) for the handling of messages exchanged between a signalling layer of the Core Network and the one or more node(s) serving as the Home Location Register (HLR) as well as the node serving as the Home Subscriber Server (HSS). The Core Network is arranged such that for an exchange of information between the signalling layer and the Interworking Function (IWF), an Intelligent Network (IN) or an Advanced Intelligent Network (AIN) is used.

Interworking function between an intelligent network and a home location register/home subscriber server

A core network is provided for transmission of short messages in an Evolved Packet System (EPS) mobile communication network. The core network provides SMS over SGs functionality and includes: a Mobility Management Entity (MME); a Short Message Service Center (SMSC); and a unit providing an Interworking, Function (IWF) for handling of short messages; wherein the MME and the SMSC are in direct communication via the IWF with respect to communication of a short message with respect to a User Equipment (UE) having a data connection to the EPS mobile communication network.

Transmission of a short message in evolved packet system

The invention relates to a method for establishing a radio link between a non-authorized mobile radio terminal (B) and a base station (C) of a mobile radio network (D). According to the invention, an authorization is given to the mobile radio terminal (B) in order to use the base station (C) as access to the mobile radio network (D), said mobile radio terminal (B) can be authorized at least temporarily, in particular manually, and the base station (C) transmits a corresponding release notice to the mobile radio terminal (B), and a radio link between the mobile radio terminal (B) and the base station (C) of the mobile radio network (D) is established.

Method of accessing closed groups in radio access network

A common communication network with line- and packet-switching control is provided, with telecommunication services such as call-forwarding, being carried out by means of a link between a control device and a communication network. At least partially synchronized control is provided for both the line-switching and the packet-switching part of the communication system, and carries out the telecommunication services.

Communication network with line-and packet-switching control

The invention relates to a method for carrying out paging in a cellular mobile communication system. A terminal is operated in a first radio cell of the mobile communication system which is in an idle state, data is provided in a data transmission device of the mobile communication system for transmission to the terminal. According to the invention, the information is first transmitted to a radio transmission device supplying the first radio cell with radio signals, whereupon a paging is carried out or initiated by the radio transmission device in order to activate the terminal and to be able to transmit the data.
