The present invention relates to a system operable to enable shortest connection roué for a mobile means of a subscriber, when the mobile means has roamed between a home network comprised in the system, and a foreign network comprised in the system. When the mobile means requests connection to Internet, a serving means comprised in the foreign network is operable to communicate with, and to receive information regarding the connection route from, a Home Location Register comprised in the home network. The serving means is operable to route a packet to a gateway means comprised in the foreign network. The gateway means is in turn operable to allocate an IP address for the mobile means and to function as an access point to Internet.

A method for operating a wireless network, wherein a base station is provided for data communication in uplink (UL) and downlink (DL) directions with at least one mobile device, includes operating the base station in a full duplex data communication mode during communication with the at least one mobile device.

Disclosed are a relay terminal reselection method and device. A control node performs relay terminal reselection judgement for a source terminal according to a reselection triggering condition of a relay terminal, and if deciding to perform relay terminal reselection, the control node determines a candidate relay terminal list for the source terminal and determines a destination a destination relay terminal for the source terminal from the candidate relay terminal list according to auxiliary information, wherein the control node is the source terminal or a source relay terminal, such that when in the moving process of the source terminal, a target node and the source relay terminal, the source relay terminal is no longer suitable to be used as a relay terminal, the source terminal or the source relay terminal can reselect a relay terminal for the source terminal.

A wireless device switches from a first downlink bandwidth part (BWP) to a second downlink BWP identified with a downlink BWP index. Based on the second downlink BWP being configured with beam failure recovery (BFR), a first uplink BWP is switched to a second uplink BWP identified with a uplink BWP index that is the same as the downlink BWP index. The second downlink BWP is switched to a third downlink BWP. Based on the third downlink BWP not being configured with BFR, the second uplink BWP is kept as an active uplink BWP.

A system for converging fifth generation (5G) communication systems for supporting higher data rates beyond fourth generation (4G) systems with a technology for Internet of things (IoT) is provided. The communication method and system may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A system is provided for determining system information validity by acquiring and storing a first system information block and other system information, including information on a public land mobile network (PLMN) identity and a value tag, and determining whether the stored system information is valid for the cell. As another example, a terminal and base station are provided for performing beam failure detection and a recovery procedure using first and second configuration information for beam failure recovery (BFR) and if failure is detected, initiating a first random access (RA) procedure and if second configuration information is received while the first RA procedure is ongoing, terminating the first RA procedure and initiating a second RA procedure based on the second configuration information.

Embodiments of a multiband central controller, a multiband communication station and methods for multiband network operations are generally described herein. In some embodiments, the central controller may be configured for multiband operations within non-coextensive frequency bands. The central controller may transmit a response frame to a receiving station that includes two or more multiband elements. Each multiband element includes a basic service set identification (BSSID) and may indicate an available channel and a frequency band associated with the available channel. The frequency band may be one of the non-coextensive frequency bands within which the central controller is operating. The multiband elements may provide frequency band and channel information to the station prior to the station joining a network that is managed by the central controller.
