Abstract

The invention discloses a heterogeneous network baton handover method supporting M2M (Machine to Machine) communication. A network is formed by a CDMA (Code Division Multiple Access) network system and an LTE (Long Term Evolution) network system. The method comprises the following steps of: when an M2M gateway needs to be carried out with handover, firstly carrying out hard handover on the CDMA network, and enabling the LTE network to bear all business data before handover; after the completion of a handover process of the CDMA network, redialing, and carrying out handover on the LTE network, wherein the CDMA network is responsible for all service flows before the handover of the LTE network; and after the completion of the handover of the LTE network, redistributing the service flows. The CDMA and the LTE adopt hard handover, and compared with soft handover, the waste of a large amount of channel resources is reduced. The baton handover method ensures continuity of business transmission in a handover process, so as to solve the problem that business is interrupted in the hard handover process.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to a heterogeneous network relay handover method supporting M2M communication. Background technique

[0002] M2M is the abbreviation of Machine to Machine, which mainly refers to the communication technology and means between machines. With the development of communication technology and society, on the one hand, the continuous development of communication technology has provided a technical basis for various applications based on communication technology, making services that were originally impossible; on the other hand, the development of society has also continuously proposed Update broader application requirements. Therefore, people put forward the basic characteristics of "ubiquitous", "all-encompassing" and "omnipotent" to help human beings realize "4A" communication, that is, at any time (anytime), any place (any-where) , anyone (anyone), anything (anything) c...
