Methods and apparatuses for communication, devices, and a storage medium are provided in the disclosure. The disclosure relates to the field of mobile communication. The method includes the following. Receive a first container transmitted by a first device, where the first container contains a first request message, and the first request message is used to request invocation of a service of a second device. Transmit the first container to the second device. A first network element serves as a bridge for communication between the first device and the second device to realize transmission of a container, such that the first device can invoke the service provided by the second device, which breaks through the limitation that only network elements in a core network can invoke services provided by network elements, and expands the scope of services provided by the core network, thereby improving communication.
