Abstract: A framework layer sends first SDP offer information including first media description information to a second communication apparatus via an IMS network element. The first media description information is description information, offered by a first application, of a media resource of a first data channel for transmission of application data generated or consumed by the first application, and both the framework layer and the first application run on a first communication apparatus. The framework layer receives, via the IMS network element and from the second communication apparatus, first SDP answer information including second media description information. The second media description information is an answer to the first media description information. The framework layer sends the second media description information to the first application.

Abstract: In some implementations, an automated self-testing system may include an electric field source and a controller. The controller may detect a trigger event associated with initiating a self test of an electric field sensing device. The controller may cause, based on the trigger event, the electric field source to create a target electric field at a specific location sensed by the electric field sensing device. The controller may receive measurement data indicating a measured electric field strength, detected by the electric field sensing device, of the target electric field. The controller may determine, based on the target electric field strength and the measured electric field strength, whether the electric field sensing device passes the self test or does not pass the self test.

The method includes: obtaining, by a network decision device, service information of a terminal, constructing network use indication information, and delivering the network use indication information to a network trigger device; and triggering, by the network trigger device based on the network use indication information, the terminal to use a wireless network corresponding to the service information. According to the method, an operator can assign, based on a service requirement of the operator, the terminal to use a specific wireless network, so that the terminal can use in time a wireless network that is consistent with a requirement of the operator. This helps improve network use efficiency for the operator, and can prevent a service of the terminal from being affected.
