Abstract: A system and method for optimizing handover parameters for a plurality of mobile terminals on a common transportation platform in a cellular network includes at least a first terminal and a second terminal and a controller. The controller is configured to determine that each of the first and second terminal are on the common transportation platform, monitor a status of a handover attempt of the first terminal, and if the handover attempt is successful, adopt handover parameter settings of the first terminal for the second terminal, and if the handover attempt is not successful, change handover parameter settings for the second terminal.

Abstract: A client device includes a processor and a memory. The client device is caused to obtain a first indication indicating an outcome of a link monitoring procedure associated with a serving link between a network access node and the client device. The client device is also caused to obtain a second indication indicating an outcome of a link re-configuration procedure associated with the serving link. The client device is further caused to determine a value of a first counter associated with a radio link failure timer based on the first indication and the second indication. The client device is additionally caused to start the radio link failure timer when the value of the first counter is equal to or larger than a first counter threshold value.

Abstract: A network node for a wireless communication system is configured to localize a user node in a first localization operation carried out at a first frequency; determine an accuracy value associated with the first localization operation; and adjust at least one beam parameter for radio beams to be used in a second localization operation based on the determined accuracy value, the second localization operation carried out at a second frequency that is greater than the first frequency. The network node is configured to determine the accuracy value associated with the first localization operation by tracking a rate of change of an angle of a radio beacon signal transmitted from the user node relative to the network node.

Abstract: A network node includes an antenna array having a plurality of antenna sub-arrays. A switching device is coupled to the antenna array, the switching device being configured to connect at least two input signals to respective ones of the plurality of antenna sub-arrays. A processor is configured to determine a channel capacity, wherein based on the channel capacity, the processor is configured to control the switching device to switch a connection of the at least two input signals to different ones of the plurality of antenna sub-arrays to change one or more of an inter-distance between the respective ones of the plurality of antenna sub-arrays and a down-tilting angle of the antenna array.

Abstract: An information sharing solution includes sending, by a first client, a uniform resource locator (URL) of a to-be-shared web page to a reverse proxy server, then acquiring a sharing URL from the reverse proxy server, acquiring, according to the sharing URL, a first to-be-shared web page that includes user background information of the first client, and sending the sharing URL to a second client, after URL synchronization between the first client and the second client, sending a document object model (DOM) of the first client to the second client such that the second client modifies a DOM of the second client according to the DOM of the first client to keep the DOM of the second client synchronized with the DOM of the first client, and after DOM synchronization between the first client and the second client, information sharing is implemented between two users.

Abstract: This application provides a data sending method, a data sending apparatus, and a terminal device, to improve utilization of a configured grant resource. The method includes: A terminal device receives a configuration message from a network device. The configuration message is used to indicate a configured grant, and the configuration message includes information about a timer corresponding to the configured grant. The terminal device determines that the configured grant is used for a HARQ process, and starts the timer for the HARQ process. To-be-sent data in the HARQ process is data on a first logical channel. During running of the timer, when there is to-be-newly-transmitted data on a second logical channel, the timer stops running, or a running state of the timer is ignored. The data on the second logical channel is sent by using the configured grant.

Abstract: The present disclosure relates to an access network node for a wireless communication system. The access network node is configured to act as a source access network node or as a target access network node, and comprises a transceiver configured to receive a handover instruction from a control device, the handover instruction comprising a handover time instance for a user device, a processor configured to serve the user device by maintaining a data connection with the user device until the handover time instance, and share an Automatic Repeat Request/Hybrid Automatic Repeat Request, ARQ/HARQ, process with a target access network node for the user device; or serve the user device by maintaining a data connection with the user device after the handover time instance, and share a ARQ/HARQ process with a source access network node for the user device.

Abstract: Webpage loading methods and devices include, in addition to sending an address of a first webpage to a server, a client further sends a name of a first-webpage resource stored in the client, such that the server can determine, according to the address of the first webpage and the name of the first-webpage resource stored in the client, a first push resource to be sent to the client, where the first push resource is all the resources required for loading the first webpage apart from the first-webpage resource stored in the client, which avoids pushing, by the server to the client, a resource that has been locally stored in the client, and therefore saves a bandwidth resource of a communications network.

Abstract: A multicast method, apparatus, and system for a software-defined network are presented, where the method includes creating, by a multicast sending device, a multicast group; managing, by the multicast sending device, a member of the multicast group; and completing, by a multicast routing tree management service module disposed on the multicast sending device or on a SDN controller, planning of a multicast routing tree, and converting the planning of the multicast routing tree into a flow entry modification instruction that can be executed by the SDN controller, so that the SDN controller executes the flow entry modification instruction and instructs an SDN switch using a southbound API to execute, according to a modified flow entry, a multicast task. Therefore, multicast is completed by means of mutual cooperation between the multicast sending device and the SDN network.

Abstract: An account login method detects whether an account login request carries an indicator for keeping a logged-in state to determine whether a user decides to keep a logged-in state, and authentication information allocated by an integrated data services platform is stored when it is determined that a logged-in state on a third-party application or website needs to be kept; therefore, in a subsequent login process, the third-party application or website may use the authentication information to automatically perform authentication login to the integrated data services platform.
