A method implemented in a user equipment (UE) includes connecting to a WLAN access point. The method further includes constructing a domain name for a packet system network, the domain name including network partition information for the packet system network. The method further includes transmitting, to a DNS server via the WLAN access point, the constructed domain name. The method further includes receiving, from the server, at least one address corresponding to a network node associated with the network partition information.

Methods and devices for selecting network partition in untrusted WLAN access

A core network node identifies a non-USIM based authentication procedure to be utilized by a wireless communication device, WCD, being served by the core network node. The node obtains a session key associated with the identified non-USIM based authentication procedure. The node converts the session key associated with the identified non-USIM based authentication procedure to i) a first key, K, for use by the WCD and a base station serving the WCD to derive an encryption or integrity protection key, K, for enabling encryption or integrity protection of a communication between the WCD and the base station or ii) a second key, K, for use by the WCD and the core network node to derive the first key K. The node then send i) Kto the base station or ii) Kto another core network node that is configured to derive Kfrom K.

Method, apparatus, and system for providing encryption or integrity protection in a wireless network

A method implemented in a control node includes receiving a message from a first node. The method further includes determining whether the received message corresponds to one or more network partitions based at least in part on the partition selection information. The method further includes selecting, in response to determining that the message corresponds to the one or more network partitions, a particular network partition from the one or more network partitions using the partition selection information, and routing the message to a second node associated with the selected particular network partition.

Method and control node for selection of a network partition and corresponding routing of a received message

A method is performed in a network control entity that manages network connections for a network. The method includes receiving a network attachment request from a network access entity or a user equipment for connecting the user equipment to the network. The method further includes obtaining a network partition ID associated with the UE, the network partition ID identifying a network partition that includes a predetermined group of network entities included in the network. The method also includes transmitting, to a network storage entity, a notification containing the network partition ID.

Methods and network nodes for network partition preservation at inter-access handovers

A device for generating signals by bringing four input signals in the microwave range together, which signals are the sum and differences between various combinations of the input signals, has waveguides arranged in a first and a second parallel plane, located next to each other. The waveguides of the first plane have parallel input ports to a first and a second magic T in which the four input signals are added in pairs, as well as waveguides by which the input signals added in pairs are supplied to the input ports of a third magic T where they are added to generate a first output signal, and subtracted to generate a second output signal. In the first and second magic T the four input signals are subtracted in pairs. The input signals subtracted in pairs are transferred to waveguides in the second plane by which they are supplied to a fourth magic T arranged in the second plane. In this magic T the signals are added, and a third output signal is generated.
