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.

Antenna switching method and related device

Embodiments of the present invention disclose a method including: determining whether, in an end-to-end link in which a voice service is performed between a first terminal and a second terminal, at least one logical functional entity that is capable of providing only a voice service of a low voice quality codec scheme exists between a network device and the second terminal, where all logical functional entities, in the link, between the network device and the first terminal are capable of providing a voice service of a high voice quality codec scheme; and if at least one logical functional entity that is capable of providing only the voice service of the low voice quality codec scheme exists, in the link, between the network device and the second terminal, setting up, for the first terminal, a radio bearer used to perform the voice service of the high voice quality codec scheme.
