Problems solved by technology

Since the target BSS does not have the MS-related eBSS Context of the source BSS, such as IOV-UI / IOV-I, and LLC / SDNCP-related exchange flags (XID, eXchange IDentifier), encryption and decryption, compression and decompression of data in the subsequent process cannot be performed Function

Embodiment 1

[0085] Using the first embodiment of the base station subsystem context download method provided by the present invention, the eBSS Context information of the source eBSS can be transferred to the target eBSS, thereby completing the recovery of protocol entities such as SNDCP and LLC on the target eBSS, so as to successfully complete Cell Update and Routeing Area Update .

[0086] Furthermore, when the SGSN / MME receives the download eBSS Context request initiated by the target eBSS, if the PS signaling connection between the SGSN / MME and the source eBSS still exists, it can use the SRNSCONTEXT REQUEST message and SRNS CONTEXT RESPONSE message to initiate an upload to the source eBSS eBSS Context request, at this time, the process of Embodiment 2 of the base station subsystem context download method provided by the present invention is as follows Figure 9 Shown:

[0087] Step 501, the target eBSS sends an SRNS CONTEXT REQUEST message to the SGSN / MME, requesting to download th...

Abstract

The invention discloses an upload method for the context of a base station subsystem which includes: a message which carries the context of the base station subsystem is constructed and the message which carries the context of the base station subsystem is sent to a general packet radio services support node or a mobile management entity. The invention also discloses a download method for the context of the base station subsystem which includes: the message which carries the context of the base station subsystem which is sent out by a source enhanced base station subsystem is received, the carried context of the base station subsystem thereof is stored, the context request of the base station subsystem which is sent out by a target enhancing base station subsystem is received and the message which carries the context of the base station subsystem is sent out to the target enhancing base station subsystem after the context request of the base station subsystem which is sent out by a target enhancing base station subsystem is received. The invention also discloses a corresponding device. By adopting the invention, LLC and SNDCP move downward to a BSS and come out of an Iu-PS interface to successively accomplish the process adaptation of Cell Update and Routeing Area Update.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a base station subsystem (BSS, Base Station System) context (Context) upload method, download method and device. Background technique [0002] Now, the third-generation mobile communication technology (3G, Third Generation) and the long-term evolution (LTE, Long Term Evolution) system are more and more widely used in the field of communication technology, but the GSM system that originally belonged to the 2G category will not be in the short-term In the long-term practical application, the GSM system has laid a solid market foundation, and has a global network coverage and a mature business application system, so it will coexist with the 3G and LTE systems for a long time. [0003] With the development of Enhanced Data rates for GSMEvolution (EDGE, Enhanced Data rates for GSMEvolution) air interface technology, the GSM system's ability to support data services has ...
