The embodiment of the invention discloses a session migration method, device and system, which relate to the communication field and are used to improve the success rate of session migration. The method provided by the embodiment of the present invention includes: the first device sends the capability identification information of the first device to the SMN, so that the SMN sends the capability identification information and the user identification of the user to which the first device belongs to the PN, and then makes the PN transmit the capability identification information according to the capability identification information, the user ID of the user to which the first device belongs, and the pre-stored service registration information to obtain the device list, and send the device list to the SMN; the first device receives the device list sent by the SMN; the first device selects the second device from the device list ; Perform session migration between the first device and the second device.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for session migration. Background technique [0002] Session migration is the migration of a service running on one device to another device according to the user's needs, so as to facilitate the user's use. on your phone or tablet. [0003] Implementing session migration requires device discovery technology and session migration technology, wherein the device discovery technology is used to determine the target device that can perform session migration; the session migration technology is used to migrate the session to the target device. At present, the technical means used to realize the two technologies include: Service Location Protocol (Service Location Protocol, SLP for short), Universal Plug and Play protocol (Universal Plug and Play, UPnP for short), Personal Network (Personal Network, PN for short), Or by evaluating the relationship between...
