Mobility management method and device of mobile originated only (MO) equipment

Abstract

The invention discloses a mobility management method of mobile originated only (MO) equipment, comprising the following steps: when the MO equipment determines that data are required to be sent, judging whether an existing location area is registered by the MO equipment; if the existing location area is registered, carrying out a service request process by the MO equipment and a network-side; and if the existing location area is not registered, establishing a user plane connection in location update by the MO equipment and the network-side. In the invention, when the MO equipment is not provided with data to be sent, even if the MO equipment enters into a routing area (RA) which is not a registered location area, a routing area update (RAU) request is not sent, or even if the MO equipment enters into a tracking area (TA) which is not a registered location area, a tracking area update (TAU) request is not sent, thus saving the signaling overhead. In addition, in the process of a follow on request of the RAU or an active flag of the TAU, the location update and the user plane establishment can be implemented in primary connection, thus improving the system efficiency and the utilization rate of air interface resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobility management method and equipment for MO equipment. Background technique [0002] MTC (Machine Type Communication, Machine Type Communication) refers to the communication between machines through the communication network of the mobile operator. [0003] MTC Device (Machine Type Communication Device) refers to the terminal equipment dedicated to machine type communication in the communication network, such as remote meter reading equipment, video surveillance equipment, etc. It can be seen that MTC Device is a special type of communication terminal. [0004] MTC Server (Machine Type Communication Server, Machine Type Communication Server) refers to a device that communicates with MTC Device through a communication network. The MTC Server is equivalent to a server, for example, a server of an intelligent meter reading system, an intelligent bus system serve...

Problems solved by technology

[0011] However, when the above method is used to reduce the frequency of mobility management, it is still impossible to avoid the TAU process that occurs when the moving MO device crosses the TAI List boundary. At this time, mobility management is still required, so the MO cannot be well optimized. Device Mobility Management

For example, for a sensor MO device fixed on a bird, it is assumed that the system is preset to send data once a month. In fact, the MO device only needs to establish a connection with the system when sending data. However, due to the movement of the MO device, when not sending data It is also possible to perform TAU frequently; furthermore, due to the large number of MTC devices, a large amount of unnecessary signaling overhead is caused, which reduces the efficiency of the system and increases the cost of operation and maintenance.
