Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, a multi-mode terminal non-access stratum handover method of the present invention will be further described in detail in conjunction with the accompanying drawings and embodiments below, and the known implementation methods will not be described in detail. Unnecessary confusion with the content of the present invention is avoided. In order to illustrate the processing process of the terminal when switching between UTRAN / GERAN and E-UTRAN networks in the present invention, two specific embodiments will be used for illustration, that is, the terminal switches from TD-SCDMA / GSM access mode to LTE access mode The processing process of the mode, and the specific processing process of the terminal switching from the LTE access mode to the TD-SCDMA / GSM access mode.

[0024]In an embodiment, the terminal is a multi-mode single-band automatic switching terminal that supports TD-SCDM...

Abstract

The invention provides a method for switching a non-access stratum of a multi-mode terminal, comprising the following steps of: in the process of switching the non-access stratum, by utilizing the characteristic of a mobile management module stored with packet data protocol context (PDP Context) / default enhanced packet service bearer context (EPS Bearer Context) identifications, after the mobile management module receives switch instruction of an access stratum, respectively informing different session management (SM) / ESM (Enhanced Session Management) examples corresponding to a PDP Context and an EPS Bearer Context according to a network service access point identification (NSA PI) / special EPS Bearer identification (EBI); and establishing ESM / SM examples by respective SM / ESM examples so that non-access switch operation of different systems is completed. Based on the traditional network architecture, the invention further provides an achievable method for switching the non-access stratum of the multi-mode terminal. The overhead cost is saved.

Description

field of invention [0001] The present invention relates to a mobile communication terminal switching method, in particular to Universal Terrestrial Radio Access Network (abbreviated: UTRAN), GSM / EDGE Access Technology Network (abbreviated: GERAN) and Enhanced Universal Terrestrial Radio Access Network (abbreviated: E-UTRAN) The switching method between them, that is, the method of interactive operation between the session management (abbreviation: SM) module in UTRAN / GERAN non-access stratum (abbreviation: NAS layer) and the enhanced session management (abbreviation: ESM) module in E-UTRAN . Background technique [0002] The GERAN network refers to the part of the access network that supports GSM / EDGE wireless access, and the UTRAN refers to a general-purpose terrestrial wireless access network. The actual wireless access technology used is Time Division Synchronous Code Division Multiple Access (TD- SCDMA) and wideband code division multiple access technology (referred to ...
