A communication system, a UE (User Equipment), a communication method and a computer readable medium may be provided. The communication system () includes: a first UE (User Equipment) () including a first controller and a first transceiver, wherein the first controller is configured to control the transceiver to send a message including L2 ID (Layer 2 Identity) and verification information; and a second UE () including a second controller and a second transceiver, wherein the second controller is configured: to control the transceiver to receive the message from the first UE (); and to determine whether to accept the L2 ID or not using the verification information.

Method and device for reducing security risk in communication

Many commercially deployed devices support more than one SIM cards. Support for multi-USIM is currently handled in an implementation-specific manner without any support from 3GPP specifications. With the increased complexity of 5G-capable UEs and with growing demand for multi-USIM devices in the market, it becomes important to consider system enhancements that would allow for more efficient solution involving required support to UE from 5G core and 5G-RAN.

System and method of dual-SIM UEs operation in 5G networks

A method for providing a key derivation function (KDF) negotiation in a 5G network is provided. The method which includes: selecting a specific KDF at a UE and at the network for at least one security related key derivation; and transmitting, said selected KDF to the UE and to other network functions to indicate said selected KDF for generating specific security key at a receiver side.

Method, UE, and network for providing KDF negotiation

In an example, a wireless communication system and apparatuses thereof are described. In an example long-term evolution (LTE) network, a first base station hands over a connection to a second base station. The first base station may be a (femto) home eNodeB (HeNB) or (macro) eNodeB. The second base station may also be a HeNB or eNodeB connected to a different gateway. The first base station may send 'Handover Request' on an X2 connection, identifying the gateway that the second base station is connected to as the correct gateway. After sending a 'Handover Request Acknowledgement,' the second base station correctly establishes a tunnel to a connected gateway device.

Call preservation on handover

An example method for facilitating almost blank sub-frame (ABS) based orthogonal resource allocation in a wireless network environment is provided and includes receiving at a serving Evolved Universal Terrestrial Radio Access Network (E-UTRAN) nodeB (eNB), ABS patterns from a plurality of neighboring eNBs in a orthogonal frequency-division multiplexing based network, each neighboring eNB transmitting a separate ABS pattern, setting a maximum duty cycle of physical downlink control channel in a frame to be transmitted by the serving eNB within its serving cell, and computing an optimal ABS pattern at the serving eNB subject to the maximum duty cycle and based on the ABS patterns received from the plurality of neighboring eNBs. In specific embodiments, computing the optimal ABS pattern includes identifying neighboring eNBs transmitting at each sub-frame of the frame, identifying sub-frames transmitted by a least number of neighboring eNBs, and selecting each identified sub-frame for configuring as an ABS.

A system and broadband device for performing service admission control. The system and device being configured to grant services according to their priority level so that, when a service with low priority has been granted and a service with higher priority is requested later on, the service with low priority is cancelled and the service with high priority is granted in case a resource is not able to support both the service with low priority and the service with high priority.

Method and system for performing service admission control

The invention concerns a method at a base station device for performing service admission control, the base station device comprising an interface to a cellular network, and an interface to connect to a broadband device, the base station device being adapted to provide service access to devices of the cellular network, the service being provided through the broadband network. To this end the method comprises the steps of receiving a service admission request from a device of the cellular network, sending a resource reservation request to the broadband device for enabling said service on the broadband network, receiving a resource reservation response from the broadband device and responding to the device of the cellular network on the availability of the service, the availability depending on the service admission response received from the broadband device.

The present invention concerns a cellular device access point device and a method at a cellular access point device for configuring a set of parameters at the cellular access point device comprising receiving and storing a set of identifiers and a set of parameters values, each identifier corresponding to a different set of parameters values, receiving, from a cellular management system, an identifier corresponding to an environment where the cellular access point device is located, and setting the parameter to the values corresponding to the identifier.
