A method of authenticating a mobile station on an alternate communications network is disclosed, the mobile station being associated with a default communications network. The mobile station comprises a baseband processor to manage the antenna-related functions and a SIM card to accommodate a default SIM associated with the default communications network for receiving network credentials from the baseband processor. The method comprises providing a SIM card device to intercept communications between the baseband processor and the SIM card, monitoring the network credentials in respect of the network that the mobile station is actively in communication with, determining whether the mobile station needs to switch to an alternate network, and identifying or receiving from a user the alternate network, consulting a SIM bank, comprising at least one alternate SIM, and selecting an alternate SIM having a mobile station identification variable compatible with the alternate network, receiving a network authentication request on the mobile station from the alternate network, and allocating the selected mobile station identification variable to the mobile station so as to identify the user of the mobile station on the alternate network.

A Machine-to-machine (M2M) terminal (11) comprises a radio communication unit (111) and a controller (112). The radio communication unit (111) is configured to communicate with a base station (13). The controller (112) is configured to change at least one of a cell selection operation, a cell reselection operation, and a handover operation according to whether a specific coverage enhancement processing is required or according to whether the specific coverage enhancement processing is supported by at least one of a cell (13) in which the M2M terminal (11) camps on and a neighbouring cell (14) of the cell (13) which the M2M terminal (11) camps on. It is thus possible to provide an improved technique for allowing the M2M terminal that is supporting a special coverage enhancement processing for M2M terminals to camp on an appropriate cell.

A method and apparatus for transmitting a local home network identity (LHN ID) in a wireless communication system is provided. A first evolved NodeB (eNB) transmits an X2 Setup Request message including a LHN ID of the first eNB to a second eNB, and receives an X2 Setup Response message including a LHN ID of the second eNB from the second eNB. The first eNB may determine whether or not to trigger a secondary eNB (SeNB) addition procedure according to the LHN ID of the second eNB. When it is determined that the LHN ID of the second eNB is the same as the LHN ID of the first eNB, the first eNB may trigger the SeNB addition procedure.

We disclose various embodiments of methods and apparatus for processing handovers of mobile terminals between base stations of a wireless communication system. An example handover algorithm used for this purpose enables the handover threshold to be increased for some mobile terminals, on a terminal-by-terminal basis, thereby individually expanding the range of the serving cell for each of such terminals. In an example embodiment, the handover-threshold determination is carried out based on physical-resource-block usage of the target cell. The extent of the cell-range expansion depends on whether or not the reference signals of the serving and target cells interfere with each other. Embodiments of the disclosed handover algorithm can advantageously reduce the number of failed handovers by allowing some communication sessions to run to completion before a handover is triggered.

A mobile station in a wireless communication network. The mobile station includes a radio communication that transmits an access request message to a base station via a first communication resource, and receives a timing adjustment in response to the access request message from the base station. The mobile station also includes an adjustment value storage unit that stores the timing adjustment, and a control unit that adjusts access timing corresponding to a second communication resource based on the timing adjustment value stored in the adjustment value storage unit. The radio communication unit then communicates with the base station via the first communication resource and the second communication resource.

The present disclosure describes a communication method, including: sending, by a user equipment (UE), a request message to a micro network node, so that the micro network node sends an indication message to a macro network node; receiving an uplink resource sent according to the indication message by the macro network node; and sending uplink signaling or uplink data to the macro network node according to the uplink resource. The present disclosure further describes a corresponding device and system. The micro network node participates in accessing the user equipment (UE) to a network so that a UE can rapidly access the network and reduce access delay.

An AP information management entity of a cellular system transmits a request for information on an AP to an AP server, and receives a response, which includes a result code of the request, from the AP server. The AP information management entity of the cellular system may be one of an eNodeB (eNB), mobility management entity (MME), or a new entity of the cellular system.

An example system includes a server communicatively connected to a cellular base transceiver station having an RF coverage area and configured for RF communication with a first entity that is a transceiver device in the RF coverage area, wherein the server comprises a first publish-subscribe broker that is part of a publish-subscribe broker network that comprises one or more publish-subscribe brokers, wherein a second entity connected to any of the one or more publish-subscribe brokers in the publish-subscribe broker network accepts communications from the transceiver device if the second entity subscribes to data packets published by the transceiver device, and wherein the data packets published by the transceiver device are routed through the publish-subscribe broker to which the second entity is connected.

A first method (and related first apparatus) includes transmitting, in a handover request message, an indication of a first protocol version; a second method (and related second apparatus) includes receiving, in the handover request message, the indication, deciding, based on the received indication and a second protocol version, on a value of an information element included in a handover request acknowledgement message to be transmitted, the information element indicating usage of a first or second signaling scheme, and transmitting the handover request acknowledgement message including the information element; and in the first method receiving the handover request acknowledgement message including the information element; and a third method (and related third apparatus) including receiving the handover command message including the information element, and configuring according to one of the first and second signaling schemes indicated by the information element.

A wireless communication system transmits information to a communication terminal moving through a spot wireless area. In an integrated base station, an external information communication section controls communication with a server. A contents memory section stores contents received from the server. A wireless LAN communication section communicates with the communication terminal. A control section establishes connection with the communication terminal using a first connection not requiring an authentication procedure for connection with the communication terminal or using a second connection requiring the authentication procedure for connection with the communication terminal. An access control (restriction) section permits access from the communication terminal to the contents memory section and prohibits access to the server when a type of connection with the communication terminal is the first connection and permits access from the communication terminal to the contents memory section and to the server in the case of the second connection.
