Abstract: This application provides a signaling transmission interface compatibility method and apparatus. The method includes: A first network element obtains capability information of an access and mobility management function network element, where the capability information is used to indicate that the access and mobility management function network element has a capability of performing signaling transmission with a radio access network through a target interface function network element. The first network element selects the target interlace function network element based on the capability information, where the target interface function network element is used for signaling transmission between the access and mobility management function network element and the radio access network. Therefore, according to the technical solutions provided in this application, the first network element obtains the capability information of the access and mobility management function network element, and selects the corresponding target interlace function network element based on the capability information.

Abstract: A method, an apparatus, and a system for paging processing and information displaying are disclosed. The paging processing method includes: receiving a paging request message from a Mobile Switching Center (MSC) which a called User Equipment (UE) registers to; and when the called UE is connected, sending a paging notification message to the called UE, and returning a called-UE paging status message to the MSC. In the embodiments of the present invention, after the Mobility Management Entity (MME) receives the paging request message from the MSC, if the called UE is connected, the MME not only sends a Circuit-Switched (CS) paging notification message to the called UE, but also returns a paging status message to the MSC, indicating that the called UE has received the paging notification message.

Abstract: Embodiments of the present application provide a method for a handover without a default bearer. A first network device sends a relocation request to a second network device. The second network device establishes a connection to a third network device indicated by the relocation request, and sends a response to the first network device and indicates that data is to be sent by using a signaling plane. Then the first network device instructs a source network device to forward the data to a target network device according to a forwarding mode indicated by a handover command. Alternatively, after the second network device establishes the connection to the third network device indicated by the relocation request, the third network device caches data, and after a handover of user equipment is completed, the third network device sends the cached data to the second network device.
