Embodiment Construction

[0023] figure 1 is a block diagram depicting a radio communication network such as Long Term Evolution (LTE), LTE-Advanced, Third Generation Partnership Project (3GPP) Wideband Code Division Multiple Access (WCDMA) system, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) , Global System for Mobile Communications / Enhanced Data Rates for GSM Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMAX), or Mobile Ultra-Broadband (UMB), just to name a few.

[0024] The user equipment 10 is comprised in a radio communication network. The user equipment 10 is served in a first cell 14 controlled by a first radio base station 12 . The user equipment 10 is moving towards a second cell 16 controlled by a second radio base station 13 . Radio base stations 12, 13 provide radio coverage within geographical areas, forming respective cells 14, 16. The first user equipment 10 in the first cell 14 communicates with the first radio base station 12 in an up...

Abstract

Embodiments herein relate to a method in a user equipment (10) for handling a radio link failure in a radio communications network. The user equipment (10) is served in a first cell (14) controlled by a radio base station (12) and which radio base station (12) is comprised in the radio communications network, The user equipment (10) detects a first indication of a failure of a radio link between the user equipment (10) and the radio base station (12). The user equipment (10) then transmits a second indication of radio link failure to the radio base station (12) when the first indication is detected.

Description

technical field [0001] Embodiments herein relate to a user equipment, a radio base station and methods therein. In particular, embodiments herein relate to enabling user equipment to establish a connection in a radio communication network. Background technique [0002] Many different technologies are used in today's radio communication networks, such as Long Term Evolution (LTE), LTE-Advanced, Third Generation Partnership Project (3GPP) Wideband Code Division Multiple Access (WCDMA) systems, Global System for Mobile Communications / Advanced Data rates for GSM Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMAX), or Ultra Mobile Broadband (UMB), just to mention a few. The radio communication network comprises radio base stations providing radio coverage over at least one respective geographical area to form cells. User Equipments (UEs) are served by and communicate with respective radio base stations in a cell. The user equipment transmits data to t...
