Abstract: Embodiments of this application provide antenna switching methods and apparatuses. In an implementation, a first communication device determines a first antenna identifier based on air interface transmission information, the first communication device sends the first antenna identifier to a digital switch, and the digital switch switches from a second switch state to a first switch state based on the first antenna identifier, where the first switch state indicates that a second communication device communicates with the first antenna within a first time unit, and the second switch state indicates that the second communication device communicates with a second antenna within a second time unit.

Abstract: The present invention discloses a method for admission control of a wireless communications network. The method includes: comparing waiting time for scheduling of a first service with a first admission threshold, where the first service is a service for which a bearer has been established; if the waiting time for scheduling of the first service is greater than the first admission threshold, comparing a satisfaction rate of the first service with a second admission threshold; and if the satisfaction rate of the first service is greater than or equal to the second admission threshold, allowing establishment of a bearer for a second service, where the second service is a service for which bearer establishment is requested. According to the technical solutions provided in embodiments of the present invention, system capacity of a wireless communications network can be effectively improved without requiring complex and inaccurate calculation of resource usage.

Abstract: Embodiments of the present invention provide a method, a device, and a system for sharing transmission bandwidth between different systems, and belong to the communications field. When a first communications system and one or more other communications systems share transmission bandwidth, the method includes: comparing, by a first network element in the first communications system, the sum of rates at which a service is sent to a second network element in the first communications system with bandwidth preconfigured for the second network element; adjusting, by the first network element based on a comparison result, a transmission priority of the service sent to the second network element; and adjusting, by the first network element based on transmission congestion status of the first communications system, sending bandwidth for transmitting the service to the second network element.
