Abstract: A method and system for measuring a service transmission status of a user equipment is provided. A first service station transmits a first data packet for a user equipment; the first service station determines at least one second service station that transmits a second data packet for the user equipment; and the first service station instructs the at least one second service station to measure a service transmission status of the user equipment, where the first data packet and the second data packet are different data packets of a same service of the user equipment or data packets of different services. According to the method and system, a service transmission status of a user equipment can be measured in a multi-station transmission scenario.

Abstract: The present invention provides an uplink reference signal sending method, and the method includes: sending, by a terminal device, an uplink reference signal on N1 second component carriers within a determined uplink reference signal sending time, and prohibiting, on M1 first component carriers in M first component carriers within the sending time, the terminal device from sending an uplink signal, where the first component carriers are carriers on which scheduling of uplink data transmission is allowed, and the second component carriers are carriers on which scheduling of uplink data transmission is prohibited. N1≤M1, in other words, within the sending time, a quantity N1 of second component carriers on which the uplink reference signal is sent is less than or equal to a quantity M1 of first component carriers on which sending of the uplink signal is prohibited.

Abstract: Embodiments of the present disclosure provide a multicast service transmission method, including: a terminal receives from a first cell, configuration information corresponding to an MBMS, where the configuration information corresponding to the MBMS includes: a cell identity of at least one second cell; the terminal obtains configuration information of the second cell based on the cell identity of the second cell; and receives from the second cell, an MTCH based on the configuration information of the second cell. This resolves a problem that the terminal can receive in one cell, an MCCH and the MTCH corresponding to the MBMS, and achieves an effect that the terminal device can receive, from the first cell and the at least one second cell, a same multicast service by using a carrier aggregation technology.

Abstract: The present application provides a method for accessing a wireless local area network, a base station controller, and a user equipment. The method includes: determining, by a base station controller of a user equipment, a first access point set, and sending information about the first access point set to the user equipment; and determining, by the user equipment according to the first access point set, an access point for accessing a wireless local area network. In embodiments of the present application, when a user equipment needs to access a wireless local area network through an access point to access the Internet, a base station controller may notify the user equipment of an available access point. In this way, the user equipment can access the wireless local area network directly through the available access point and does not need to request a password from an operator and enter the password during access.

Abstract: Embodiments of the present disclosure disclose a security configuration method for a radio bearer and a device. The method may include: obtaining, by a base station, a first security configuration message, where the first security configuration message is used to indicate whether security configuration needs to be performed on each of N radio bearers set up between the base station and a terminal device, and indicate security configuration parameters for M radio bearers on which security configuration needs to be performed, where N is a positive integer, M is an integer, and M≤N; and sending, by the base station, the first security configuration message to the terminal device. According to the embodiments of the present disclosure, applicability of security configuration can be improved.
