Embodiment Construction

[0039] Embodiments herein relate generally to wireless communication networks. figure 2 is a schematic overview showing the wireless communication network 1 . The wireless communication network 1 includes one or more RANs and one or more CNs. The wireless communication network 1 may use one or more of different technologies such as Wi-Fi, LTE, LTE-Advanced, fifth generation (5G), Wideband Code Division Multiple Access (WCDMA), GSM / Advanced Data Rate GSM Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMax), or Ultra Mobile Broadband (UMB), to mention just a few possible implementations. Embodiments herein relate to recent technological trends of particular interest in the context of 5G. However, the embodiments are also applicable to the further development of existing wireless communication systems such as WCDMA and LTE.

[0040] In a wireless communication network 1, a wireless device such as a wireless device 10 (e.g., a mobile station, a non-acc...

Abstract

Embodiments herein disclose a method performed by a wireless device (10) for handling connections in a wireless communication network, wherein the wireless device (10) is configured with a split signaling radio bearer to a first radio network node (12), being a master radio network node, and a second radio network node (13), being a secondary radio network node. The wireless device detects a radiolink problem to the first radio network node (12); and transmits a failure report to the first radio network node (12) over the split signaling radio bearer via the second radio network node (13). The failure report indicates the radio link problem to the first radio network node (12).

Description

technical field [0001] Embodiments herein relate to a first radio network node, a second radio network node, a wireless device, and methods performed therein relating to wireless communication. In addition, computer programs and computer-readable storage media are also provided herein. In particular, embodiments herein relate to handling connections of wireless devices in a wireless communication network. Background technique [0002] In a typical wireless communication network, a wireless device (also referred to as a wireless communication device, mobile station, station (STA) and / or user equipment (UE)) communicates with one or more core networks via a radio access network (RAN) (CN) Communications. The RAN covers a geographical area divided into service areas or cell areas, where each service area or cell area is served by a radio network node, such as an access node, such as a Wi-Fi access point or a radio base station (RBS), which A node may also be referred to as a...
