    摘要: Embodiments of the present invention provide a group communication method, a device, and a group communication system, and relate to the communications field, so as to accurately identify a cell range in which group communication data is to be broadcast and to improve utilization of a downlink transmission resource. The group communication method includes: obtaining, by a server, a first group identifier, where the first group identifier is determined based on location information of first user equipment; obtaining, by the server, group communication data sent by the first user equipment; and sending, by the server, the group communication data in a cell corresponding to the first group identifier based on the first group identifier.

    摘要: The present invention discloses a method, a device and a system for enabling a routing function and transmitting data, which relate to the field of communications, and are capable of sharing a single session task through a plurality of access points, thereby ensuring data transmission quality. When a station uses an external network identifiable address, and performs data transmission of a single session task through a first access point, an address of a CR router connected to the first access point is determined; at least one second access point connected to the same CR router with the first access point is determined; a CR enabling request message is sent to a CR router corresponding to the CR router address through each of the access points associated with the CR of the station; a CR enabling feedback message returned by the CR router and forwarded via the access points associated with the CR of the station is received, so that the station sends different data packets of the single session task through the first access point and the second access point separately. Embodiments of the present invention are mainly used for data transmission in a wireless network.

    摘要: A communications system for providing data communication to a vehicle (10), the communications system comprising: a mobile transport layer proxy (150) located on the vehicle; a parent transport layer proxy (170) located remote from the vehicle; the mobile transport layer proxy being configured to: accept a transport layer connection with a host device (32, 33), the transport layer connection being addressed to a remote server (160); and communicate with the parent transport layer proxy via multiple paths using a multipath transport layer protocol to communicate on behalf of the host device whilst identifying as the mobile transport layer proxy; and the parent transport layer proxy being configured to: communicate with the mobile transport layer proxy using the multipath transport layer protocol; and communicate with the remote server whilst identifying as the parent transport layer proxy to communicate on behalf of the mobile transport layer proxy to permit the host device to communicate with the remote server.
