Abstract: Example embodiments presented herein are directed towards a network node (401A, 401B) (e.g., a source or target base station), and corresponding method therein, for managing a user equipment time offset measurement by accounting for a user equipment mobility profile. The management may involve a source network node (401A) delaying or preventing the sending of a user equipment timing offset measurement to a target network node (401B) or sending an indication or a reliability of the user equipment timing offset measurement. The network node (401A, 401B) may further apply a compensation to the user equipment timing offset measurement to account for an expected behavior of the user equipment based on the mobility profile. The network node (401A, 401B) may also adapt an uplink search window based on the user equipment mobility profile.

Abstract: A wireless network system (10) and a method of operating a wireless network system (10) is described. The wireless network system (10) comprises at least a control device (1) and a function device (21, 21′, 21″). The control device (1) being configured to send an application control command to said function device (21, 21′, 21″) with a first network address (AD1) and the function device (21, 21′, 21″) being configured upon reception of said application control command to send an acknowledgement signal to said control device (1). The control device (1) sends conflict information to said function device (21, 21′, 21″) in case more than one acknowledgement signal is received, and said function device (21, 21′, 21″) upon reception of said conflict information stores a second network address (AD2), different from said first network address (AD1) in said device configuration memory (28), so that said function device (21, 21′, 21″) is addressable in said network system (10) using said second network address (AD2).

Abstract: The present invention proposes a method for detecting a duplicate address, a mobile station, a network element for controlling access of a mobile station to a wide area network and a communication network comprising a mobile station and at least two network element, wherein said mobile station is moving from a second access network pertaining to a second network element into a first access network pertaining to a first network element. Said method for detecting a duplicate address comprises: the mobile station sends a request message to the first network element; the first network element generates and sends a first message to the mobile station upon reception of said request message, said first message designating an explicit address configuration and including prefix information; the mobile station checks out the explicit address configuration, generates an address based on said prefix information and sends a message containing the generated address to the first network element for indicating that the mobile station requires registering the generated address with the first network element; and the first network element creates an entry for the mobile station if the generated address is not found in its address table, or generates and sends a second message to the mobile station for indicating that the generated address is a duplicate address if it is found in its address table and discards data packets with the duplicate address sent from the mobile station.

Abstract: The present invention discloses a method, an apparatus and a system for configuring an IP address, and relates to the field of data transmission technologies, to solve a problem that in the process of network renumbering, when a conflict occurs between address configuration policies of a host, adopting a local policy of the host may cause an adverse impact on a network. In the present invention, when an address configuration policy conflict occurs, a terminal reports address configuration policy conflict information to a network side, so that the address configuration policy conflict in the terminal is no longer processed by a local policy of the terminal, but processed by the network side, that is, the network side decides what address configuration policy is adopted for the terminal. Therefore, an optimal solution can be provided for the conflict according to the actual situation of the network, thereby preventing an adverse impact on the network caused by the conflict. The present invention may be applied in a network deployed with multiple address configuration protocols.

Abstract: An access device and an extender access device, forming a network for network client devices. A single IP address attribution server in the network attributes IP addresses to network devices based on their MAC address. The access device providing access in a first coverage zone. The extender access device providing access in a second coverage zone. The extender access device implements MAC address translation for representing network client devices in the second zone before the access device. When a network client device roams from the second zone to the first zone, the client device keeps its IP address that was attributed to it by the IP address attribution server via the extender access device even if the client device requests an IP address with its real, non-translated MAC address.

Abstract: A wireless communication device includes a wireless communication unit, a storage unit and a processor. The wireless communication unit performs near field communication with another wireless communication device. The storage unit stores an other-device address which is identification information of said another wireless communication device and which is acquired through the wireless communication unit. The processor updates an own-device address which is identification information of the wireless communication device, when receiving an instruction for excluding the other-device address from a connection destination of the near field communication.

Abstract: A particular method includes receiving, at an access point, a set up message from a station. The set up message requests allocation of an internet protocol (IP) address. The method further includes selecting an available IP address from a pool of available IP addresses to assign to the station based on the set up message. The method further includes assigning the available IP address to the station as an assigned IP address. The method also includes transmitting a set up response to the station. The set up response identifies the assigned IP address.

Abstract: In a mobile communication system, cell-wide short identifiers are assigned to the mobile transceivers by the base station transceiver to reduce the overhead of long addresses (e.g., globally unique). The base station obtains information about a number of mobile terminals and determines the appropriate bit-length of the identifiers of the terminals. If new terminals join the cell and there are no more identifiers available, the base station increases the bit-length and notifies (e.g., through a broadcast message) the terminals about the change. Similarly, when terminals leave the cell, the base station may decide to reduce the length of the identifiers. The updates can be performed respectively by prepending a pre-defined digit or removing a digit. As digit removal may lead to collisions (i.e. same identifier for multiple terminals), the base station should individually provide replacement identifiers to affected terminals.

Abstract: A device implementing a dynamic local media access control (MAC) address assignment system may include at least one processor circuit. The at least one processor circuit may be configured to transmit an address request packet including a proposed MAC address and a device identifier to devices on a network. The at least one processor circuit may be further configured to determine whether any reply packets are received that indicate that another device has claimed the MAC address prior to expiration of a probe timer. The at least one processor circuit may be further configured to transmit an address claim packet including the MAC address when the probe timer expires before any reply packets are received from other devices. The at least one processor circuit may be further configured to communicate over the network using the proposed MAC address after transmitting the address claim packet.
