The method includes sending a request to a core network entity to register the radio access network entity with the core network entity for at least one tracking area, the core network entity being in charge of mobility management and/or paging coordination in a cellular mobile communication network. The method further includes receiving a notification of an acceptation or a rejection of said request that indicates if the core network entity has accepted the registration. The radio access network entity is configured to perform the method. The core network entity is configured to interface with the radio access network entity to perform the method.

Method for registering a radio access network entity with a core network for a tracking area, a radio access network entity thereof, and a core network entity thereof

One object of the present invention is a method for for configuring a cellular mobile communication network with Tracking Areas, comprising:

Method for configuring a mobile communication network including an enhanced node B with tracking areas

A method for Mobility Management MM in a system architecture supporting mobility between different access systems having separate Core Network CN-level MM entities while using common MM Area, the method comprising a step of: when a User Equipment UE leaves the coverage of a first one of the access systems where it is in a Non Radio Connected state as seen from Radio Access Network RAN, but seen in Connected State from CN-level MM entity, for the coverage of a second one of the access systems where it is in Idle state as seen from CN-level MM entity, putting the UE into Idle state as seen from CN-level MM entity of said first access system.

Method for mobility management in a system architecture supporting mobility between different access systems

One object of the present invention is a method for access to subscription data stored in a database entity of a mobile communication network referred to as first database entity, storing subscription data referred to as first subscription data for support to network entities of the mobile communication network entities referred to as first network entities, the method comprising a step wherein a database entity of the mobile communication network referred to as second database entity, storing subscription data referred to as second subscription data for support to network entities of the mobile communication network referred to as second network entities, communicates with the first database entity to have access to at least part of the first subscription data, a step wherein an Application Server communicates with the second database entity, to have access to the at least part of first subscription data via the second database entity.

Method for access to subscription data stored in a database entity in a mobile communication network

In one aspect, a method for Quality of Service management in a mobile communication system is provided, comprising, in an embodiment:

Quality of service management in a mobile communication system

An object of the present invention is a method for the handling of user access-dependent information in a system comprising a core network subsystem accessed by an access network, said method comprising:

Handling of user access-dependent information in a core network subsystem

A method for Mobility Management MM in a system architecture supporting mobility between different access systems having separate Core Network CN-level MM entities while using common MM Area is provided. When a User Equipment UE leaves the coverage of a first access system where it is in a Non Radio Connected state as seen from Radio Access Network RAN, but seen in Connected State from CN-level MM entity, for the coverage of a second access system where it is in Idle state as seen from CN-level MM entity, the UE is put into Idle state as seen from CN-level MM entity of said first access system.

The invention concerns a device (D) dedicated to controlling access of a terminal (UE), connected to a CS domain of a mobile network comprising a MSC center (VMSC) running CS communications, to a IMS network services of which its user is a subscriber. Said device (D) comprises: i) a GMSC module managing setup of communications to a terminal (UE) connected to the CS domain, ii) a MGCF module converting messages from the CS domain in accordance with a ISUP protocol into messages in accordance with a SIP protocol addressed to a S-CSCF module and inversely, iii) an I-CSCF initiating registration of terminals connected to the CS domain, with a S-CSCF module, and iv) a P-CSCF emulator (P) and a user agent (UA) responsible a) for co-operating together on behalf of the terminal (UE) to instruct an I-CSCF module to initiate the registration of a terminal with a S-CSCF module of the IMS network of which its user is a subscriber, b) when the user attempts via the terminal (UE) to set up a call, for sending said call, via the MGCF module, to the S-CSCF module with which it is registered, and c) upon reception of a request for setting up communication to the terminal, from the S-CSCF module of the TMS network of which its user is a subscriber, for instructing the GMSC module, via the MGCF module, to manage said setting up on the CS domain side.
