HANDOVER OF A USER DEVICE WITH FORWARDING AND REUSE OF A USER DEVICE CONFIGURATION

Abstract

A method for handing over a User Equipment (180) from a first base station (110) to a second base station (120) of a cellular telecommunication network (100), wherein the first base station (110) is a first eNodeB (110) and the second base station (120) is a second eNodeB (120) of a Long Term Evolution network (100), the method comprising• establishing a first connection (110a) between the User Equipment (180) and the first base station (110),• arranging a current configuration of the User Equipment (180) with the first base station (110),• forwarding the current configuration of the User Equipment (180) from the first base station (110) to the second base station (120) via a terrestrial interface (115),• establishing a second connection (120a) between the User Equipment (110) and the second base station (120), and• reusing the forwarded configuration of the User Equipment (180) at least partially for the operation of the User Equipment (180),when the User Equipment (180) is served by the second base station (120), characterized by- a set of configuration parameters of the User Equipment (180) is known by the first base station (110) and the second base station (120) as a default configuration- the current configuration of the User Equipment (180) is forwarded from the first base station (110) to the second base station (120) by solely forwarding configuration parameters, which deviate from the default configuration- wherein the current configuration is forwarded via an X2 interface (115),- wherein the current configuration is a measurement configuration of the User Equipment (180) characterizing measurement procedures which are performed by the User Equipment (180), and- wherein the current configuration comprises activity data of the User Equipment (180), which activity data determine activity times of the User Equipment (180),wherein the activity times are used by the User Equipment (180) as a time reference for performing measurements.,

Description

[0001] concerning European Patent 2 181 559 (DE 60 2008 005 465) The 4th Senate (Nullity Senate) of the Federal Patent Court has decided at the oral hearing on 22 January 2025 found to be right: I.

Claims

[1] A method for handing over a User Equipment (180) from a first base station (110) to a second base station (120) of a cellular telecommunication network (100), wherein the first base station (110) is a first eNodeB (110) and the second base station (120) is a second eNodeB (120) of a Long Term Evolution network (100), the method comprising • establishing a first connection (110a) between the User Equipment (180) and the first base station (110), • arranging a current configuration of the User Equipment (180) with the first base station (110), • forwarding the current configuration of the User Equipment (180) from the first base station (110) to the second base station (120) via a terrestrial interface (115), • establishing a second connection (120a) between the User Equipment (110) and the second base station (120), and • reusing the forwarded configuration of the User Equipment (180) at least partially for the operation of the User Equipment (180), when the User Equipment (180) is served by the second base station (120), characterized by - a set of configuration parameters of the User Equipment (180) is known by the first base station (110) and the second base station (120) as a default configuration - the current configuration of the User Equipment (180) is forwarded from the first base station (110) to the second base station (120) by solely forwarding configuration parameters, which deviate from the default configuration - wherein the current configuration is forwarded via an X2 interface (115), - wherein the current configuration is a measurement configuration of the User Equipment (180) characterizing measurement procedures which are performed by the User Equipment (180), and - wherein the current configuration comprises activity data of the User Equipment (180), which activity data determine activity times of the User Equipment (180), wherein the activity times are used by the User Equipment (180) as a time reference for performing measurements. [5] (entfällt) [6] (entfällt) [7] (entfällt) [10] (entfällt) [11] A first base station for a cellular telecommunication network (100), wherein the first base station (110) is a first eNodeB (110 of a Long Term Evolution network (100), the first base station (110, 210) comprising • a connection unit (211) for establishing a first connection to a User Equipment (180), • a receiving unit (212) for receiving a current configuration of the User Equipment (180) from the User Equipment (180), • a transmission unit (213) for forwarding the current configuration of the User Equipment (180) from the first base station (110, 210) to a second base station (120) via a terrestrial interface (115), wherein the second base station (120) is a second eNodeB (120) of the Long Term Evolution network (100), and • a memory unit (214) for storing configuration parameters of the User Equipment (180), which configuration parameters represent a default configuration, characterized by forwarding the current configuration information of the User Equipment by solely forwarding configuration parameters which deviate from the default configuration, wherein the current configuration is forwarded via an X2 interface (115).
