  • Patent number: 10045285
    Abstract: The present application discloses a wireless local area network access point search method, an apparatus, and a system, relates to the field of communications technologies, and can reduce power consumption for passive scanning. According to the method, beacon sending information of a wireless local area network access point and measurement information of a user equipment are matched, so that the user equipment can search for the wireless local area network access point only at the time when and a frequency channel number at which the wireless local area network access point sends a beacon. Compared with the prior art in which a user equipment needs to continuously keep a state of searching for a wireless local area network access point, the present application greatly shortens time spent by the user equipment in listening to a beacon, and therefore reduces power consumption of passive scanning.

  • Patent number: 9883439
    Abstract: The present disclosure relates to the field of mobile communications technologies, and in particular, to an offloading method and an apparatus. In this solution, when a terminal is in a handover process, a destination cellular network node sends, to the terminal, configuration information of a WLAN AP managed by the destination cellular network node; and then the terminal selects a destination WLAN AP from WLAN APs managed by the destination cellular network node, and offloads data of the destination cellular network node to the destination WLAN AP. Therefore, the destination WLAN AP selected by the destination cellular network node can be received before a handover is completed, thereby ensuring service continuity and improving service quality of a terminal.

  • Publication number: 20170330239
    Abstract: A signature matrix is used to test each online event for inclusion of a user in a pre-generated lookalike audience. Locality Sensitive Hashing is used to compile the signature matrix to dramatically reduce memory storage requirements and processing time for each received online event. A technique of producing incremental signature matrices between generation of the full signature matrix helps to enable near-real time performance in processing each received event to see if a user associated with that event should be added to one of the lookalike audiences pre-generated by advertiser.

  • Publication number: 20170164258
    Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to a resource allocation method, a service transmission method, and an apparatus, so as to resolve a technical problem of how to coordinately transmit, in a WLAN, a WLAN service and a to-be-offloaded service of a cellular network node. In embodiments of the present invention, resources separately allocated to an AP and the cellular network node are specified, and the AP and the cellular network node are separately notified of an allocation result. In this way, both the AP and the cellular network node transmit data on only the respective allocated WLAN resources, so as to avoid that the WLAN service and the to-be-offloaded service of the cellular network node contend for a channel.
