摘要： A server-implemented method for automatically registering an asset tag in a database is disclosed. One or more asset tag collision reports are received from at least one mobile device connected to the server, each report including a tag identifier of the asset tag that is wirelessly broadcast by the asset tag. A location of the asset tag is determined based on the one or more received asset tag collision reports. A first asset is selected from a set of unregistered assets that are identified as being deployed in the indoor facility based on determining that there is a match between the location of the asset tag and location information associated with the first asset. The asset tag is then registered in association with the first asset in the database.

摘要： These teachings provide for transmitting to a wireless access point a sleep status indicator for a wireless transceiver. These teachings then provide for delaying having that wireless transceiver enter a sleep mode of operation until at least a predetermined period of time following transmission of the wireless transceiver sleep status indicator. These teachings also provide for determining a need to slow down a rate of receiving data from the wireless access point via the wireless transceiver. In this case the aforementioned sleep status indicator is transmitted in response to determining that need to slow down the rate of receiving data from the wireless access point.

摘要： A device in a peer-to-peer (P2P) group has the role of group owner. A different device in the P2P group may take on the role of group owner without ending the P2P group and create a new P2P group. Multiple P2P groups may be merged into a single P2P group. A single P2P group may be split into multiple independent P2P groups, each with its own group owner. A group owner of a P2P group may notify the client devices in the P2P group that it is about to leave the P2P group. A client device in a P2P group may be appointed in a new role of backup group owner, to take on the role of group owner in the event of a departure of the group owner, thereby providing continuity. Techniques for maintaining upper layer continuity through changes in topology of P2P groups are disclosed.

摘要： A channel sharing method includes determining a starting time for transmission on an LAA-LTE channel. A length of a hybrid preamble is determined based on the starting time and a predetermined transmission time boundary. Subsequent to determining the length of the hybrid preamble, the hybrid preamble having the determined length is transmitted. Subsequent to the hybrid preamble, a Long Term Evolution (LTE) signal is transmitted.

摘要： For a computing device that employs a touch-sensitive keyboard, authentication may involve illustrating, to the electronic device, knowledge of a stored secret though providing input, at least in part, via the touch-sensitive keyboard. The input may be in the form of swipes alone or in combination with key actuations. Furthermore, the swipes and key actuations may be associated with a particular region of the touch-sensitive keyboard.

摘要： A system and method for short-range wireless peer-to-peer file sharing is provided. A consolidated catalog of accessible files stored both locally and remotely is sent by a first computing device to a peer computing device over a short-range wireless communications link. The first device receives a request from the peer device to retrieve a selected file. When this selected file is determined to be remotely stored, the first device obtains authentication credentials sufficient to permit access by the peer device to the selected file stored remotely at another device, and sends the authentication credentials to the peer device over the short range wireless communications link so that the peer device can directly retrieve the selected file from the other device using the authentication credentials.

摘要： To improve network coverage or reduce false handover triggering, at least one client terminal is set to operate as a virtual access point (VAP) in a first wireless network by an AP controller. If a mobile device detects that a signal quality estimate of communications via an AP or the first wireless network is below a first value, the mobile device performs a handover procedure to the VAP. While maintaining the call via the VAP, if the mobile device detects that the signal quality estimate is back above the first value, the mobile device performs a handover procedure back to the AP of the first wireless network. On the other hand, if the mobile device detects that the signal quality estimate is below a second value which is less than the first value, the mobile device performs a vertical handover procedure from the VAP to a base station of a second wireless network.

摘要： An apparatus has a first communication module that is compatible with a first wireless communication technology, and a second communication module that is compatible with a second, different, wireless communication technology. Transmissions by each communication module may contribute to interference at the other communication module. In one example, a Block Acknowledgement Request is transmitted by the apparatus during a downlink period of the second communication module so that the Block Acknowledgement transmitted in response is received during the downlink period. In another example, the apparatus calculates a maximum size of A-MPDU to receive and notifies an access point of that maximum size. In a further example, the apparatus, having notified an access point of operation in a power save mode, polls the access point for buffered frames at the start of a downlink period of the second communication module.
