Information management method, secondary node changing method, node, and storage medium

The embodiments of the present invention disclose a call processing method and device. The call processing method comprises: sending, by a repeater of the first site, a first call establishment request to a repeater of the second site according to a call request initiated by a first terminal, the first call establishment request comprising an identification of the second terminal; determining, by the repeater of the first site, whether a second call establishment request is received before a call establishment response sent by the repeater of the second site is received, the second call establishment request being sent by the repeater of the second site according to a call request initiated by the second terminal; and if yes, sending, by the repeater of the first site, a call collision notification to the first terminal to notify the first terminal to delay the call.

Call processing method and device

A method of data communication includes: determining, by a first terminal, an idle channel, and transmitting a data handshake request carrying interruption information on the idle channel, wherein the interruption information at least includes an indication for interrupting a call of a traffic channel; receiving a data handshake response transmitted by a repeater; when the data handshake response is of a type allowing interruption, jumping to the traffic channel designated by the repeater according to a channel jumping indication included in the data handshake response; and when determining that a second terminal occupying the traffic channel making the call interrupts the call and releases a resource of the traffic channel, initiating a call on the traffic channel. The embodiments of the present invention can interrupt the call of the transmitting terminal and release the channel resource, and have strong flexibility and high efficiency.
