A method of avoiding mass offloading of user devices, UE's (14), connected to a cellular network (15, 16) such as 3GPP LTE to a second wireless network such as a WLAN (6,8), the method comprising: an ANDSF server (12) broadcasting (in a SIB message, for example) a set of parameters representing offload thresholds to be applied by UE's in idle mode, and also additional information such as a bitmap indicating which of those parameters are also applicable to UE's in connected mode; and a user device, UE (14), receiving the set of parameters and the additional information, and deciding whether to migrate or not to the second network in dependence of whether it is in idle or connected mode, of the parameters and of the additional information.

There is provided user equipment for communicating with a base station in a mobile communication system supporting LTE including a reception unit configured to receive an indication from the base station to change a sequence number length of an RLC PDU, a re-establishment unit configured to perform re-establishment of an RLC entity upon receiving the indication, and a communication unit configured to use the RLC PDU with the changed sequence number length to communicate with the base station after completion of the re-establishment.

Embodiments provide a core network selection method, an apparatus, and a system. The method includes the following steps: obtaining first dedicated core network (DCN) information from an access network device, where the first DCN information includes information about at least one DCN that can be accessed by the access network device. The method also includes selecting a to-be-accessed DCN from the at least one DCN according to the first DCN information, and sending information about the to-be-accessed DCN to the access network device, so that the access network device determines a core network device according to the information about the to-be-accessed DCN.

A method is performed in a first infrastructure equipment for a handover of a wireless device from the first infrastructure equipment as a source to a second infrastructure equipment as a target. The method comprises maintaining a mapping between a plurality of packet bearers and a data radio bearer for the wireless device, each of the plurality of packet bearers being configured to provide a specified quality of service, determining that the wireless device should handover from the first infrastructure equipment to the second infrastructure equipment, determining that the second infrastructure equipment does not support the mapping of the plurality of packet bearers to the data radio bearer, and providing an indication of a mapping of the plurality of packet bearers for the second infrastructure equipment after handover to one of a core network equipment and the second infrastructure equipment.

A method involving a terminal (110) and an access network node (160) in an access network (100) for connecting said terminal (110) to the access network node (160) and wherein said terminal (110) and access network (100) is configurable to support and being adaptive to a plurality of robustness levels. Each robustness level corresponds to a transmission delay and loss limit which can be configured per individual traffic flow. Robustness levels for the terminal and the access network are exchanged in order optimize the end-to-end Quality of Experience, QoE. This is applicable to access networks that show large variations in terms of network performance (for example radio access networks).

The present invention relates to a method and a device for transmitting a signal of mobility, for transmission or reception of a first radio access technology (RAT)-based signal in a wireless communication system. Specifically, the method comprises the steps of: generating a first RAT-based signal including a message relating to generation of an event; duplicating the message into a second RAT-based signal when the event is associated with a safety service; and transmitting the second RAT-based signal through a resource area associated with the first RAT when the event is associated with the safety service.

A method comprises detecting (402) QUIC packets transmitted (401, 406) between network elements (UE, content server) of a communication system. Based on a detected QUIC packet, the method comprises obtaining (403), at a first measurement point and at a second measurement point, user plane customer experience measurement information and optionally context information. The method comprises providing (404), to the first measurement point, user plane customer experience measurement information and optionally context information, obtained at the second measurement point. The method comprises correlating (405) user plane customer experience measurement information obtained at the first measurement point, with user plane customer experience measurement information received from the second measurement point, by using context information obtained at the first measurement point and context information received at the first measurement point.

A method of sending cell measurement configuration information and a device thereof, and a method of receiving cell measurement configuration information and a device thereof are provided. The method of sending cell measurement configuration information includes: sending, by a network device through a dedicated signaling, to a terminal first measurement configuration information used by the terminal, where the first measurement configuration information includes cell change configuration information and indication information configured to identify the cell change configuration information; sending, by the network device, second measurement configuration information through a system broadcast message, where the second measurement configuration information includes cell change configuration indication information.

A test system is provided. Said test system comprises a device under test, a measurement equipment, and a remote source simulator. In this context, the remote source simulator is adapted to simulate a remote video source, wherein the remote video source is adapted to transmit a video comprising at least one detection pattern to the device under test. Furthermore, the device under test is adapted to display the video. In addition to this, the measurement equipment is adapted to detect the at least one detection pattern with respect to the device under test and to determine the number of detection patterns having been received by the device under test.
