Abstract: An access point node comprises a first interface configured to communicate with a radio access node of a cellular network via a radio link and further comprises a second interface configured to communicate with a terminal via a further radio link. The access point node is configured to establish an end-to-end connection with a user-plane gateway node of the cellular network in response to receiving an attach message from the terminal.

Abstract: A user equipment (10) is operable in a first mode in which the user equipment (10) is configured for communication with a first cellular network (30) and a second mode in which the user equipment (10) is configured for communication with a second cellular network (40). Mode switching between the modes is performed autonomously by the user equipment (10) or under the control of a cellular network node. The user equipment (10) has a first power consumption when operating in the first mode and a second power consumption when operating in the second mode, the second power consumption being different from the first power consumption.

Abstract: Location of an electronic device is determined using signals received from a first set of reference radios. The first set of reference radios include at least one secondary reference radio, each secondary reference radio established as a secondary reference radio by registering a corresponding location with a server. The corresponding location of the secondary reference radio is determined as a function of signals received by the secondary reference radio from a second set of reference radios. The second set of reference radios include radios qualified as reference radios in a database of primary se reference radios and secondary reference radios, each primary reference radio being a fixed-location radio device.

Abstract: The present invention relates to a method for determining a position of a terminal device (110) in a wireless communication system (100). According to the method, a first message (130-133) is broadcasted by the terminal device (110). The first message (130-133) comprises a positioning request and a terminal identifier identifying the terminal device (110). The first message (130-133) is received at a group of neighboring devices (120-123). Each neighboring device of the group of neighboring devices (120-123) is located within a wireless radio communication range of the terminal device (110). From one or more neighboring devices (120, 121) of the group of neighboring devices (120-123) a corresponding second message (140, 141) is transmitted to location server (103) of the wireless communication system (100). The second message (140, 141) comprises the terminal identifier and an indication that the terminal device (110) requested a positioning. For each neighboring device (120, 121) of the one or more neighboring devices a corresponding position information is determined. The position of the terminal device (110) is determined at the location server (103) based on the position of the one or more neighboring devices (120, 121).

Abstract: Embodiments of the present technique can provide a mobile device and a method of establishing a connection via a core network by a mobile terminal. The method comprises receiving by the mobile terminal in a first cell an identifier assigned by a node in a first core network of a first type, the identifier comprising an identifier of the node or a group of nodes in the first core network, selecting a second cell in which service via a core network of a second type is available, and determining whether service via a core network of the first type is available from the second cell. The method further comprises establishing a connection via the second cell by transmitting a message including a first indication, the first indication based on at least a portion of the identifier, and when service via a core network of the first type is not available from the second cell, transmitting in the message a second indication, the second indication indicating that the identifier was received from a core network different from the second type, without identifying the first type of core network.
