Abstract

The embodiments of the present invention disclose a method and device for obtaining security context, which relate to a communication technical field, and are invented enabling normal communication between a Machine Type Communication (MTC) device and the network side under the condition that the MTC device does not perform Tracking Area Update (TAU) / Routing Area Update (RAU). The method for obtaining security context includes the following steps: a service request is generated, the service request carries an obtaining indication of the security context (S11); the service request carrying the obtaining indication of the security context is transmitted to a new server (S12); a parameter invoking request is received, which is transmitted from the new server according to the obtaining indication of the security context (S13); an obtaining parameter of the security context is invoked according to the parameter invoking request (S14); the obtaining parameter of the security context is transmitted to the new server (S15). The embodiments of the present invention can be used in the MTC communication technique.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for acquiring a security context. Background technique [0002] Machine-to-machine M2M (Machine to Machine,) communication, also known as machine type communication MTC (Machine Type Communication), is an integrated technology of wireless communication and information technology. This technology does not require manual intervention, and can be directly communicated between machines Communication, currently has a wide range of applications in automatic instruments, remote monitoring, payment systems, etc. [0003] MTC devices usually have TAU (Tracking Area Update, tracking area update) / RAU (Routing Area Update, routing area update) functions. The main function of the TAU / RAU function is to allow the network side to obtain the location information of the MTC device, so that the network side The location information can be used to page the MTC de...
