Abstract
The invention discloses a simulation method of a protocol stack in mobile communication. The protocol stack at a mobile phone terminal is divided into an upper layer service application protocol stack and a bottom layer network element bearing protocol stack, is subdivided and encapsulated in a component manner, and is freely combined and superimposed according to the testing demands. The invention discloses the simulation method of the protocol stack facing a network element and can provide the modular multi-interface adaptation supporting capacity on a single testing system.
Description
Technical field
The invention belongs to moving communicating field, more specifically, relate to the network management technology field of data service.
Background technology
Along with the continuous enhancing of multiple voice, data business content and the application function of GSM, GPRS and TD-SCDMA and perfect, mobile communications network is when providing convenient communication service for the user, also, make its network and service availability real time implementation monitoring difficulty increase greatly owing to the complexity of its class of business, the diversity of network interface.In order to monitor all kinds of availability of traffics in real time, to detect service quality, the data service test manifests more and more important effect in line service.Because 2G, 2.5G and 3G core net network topology complexity, can reach hundreds ofly with class of business, the test job amount of network element and service availability is very heavy, and the service dial testing system just arises at the historic moment thereupon.This wherein very important link is exactly an interface simulation.
The present interfaces analogue system all is to take independently simulation method of protocol stack, and agreement and data structure according to each layer of protocol stack make up whole protocol stack, the service message of this interface of emulation and signaling message.The operational trials of distinct device distinct interface must adopt sub-module just can be achieved, the interface of different system (GPRS+TD-SCDMA) carries out Development of Module again again, if will be applied to the test of many scenes, multisystem, need to carry out according to demand again the protocol stack customization again.As seen, the method can't satisfy multi-protocols support, the adaptive demand of many interfaces, causes operator must adopt different test macros to carry out operational trials at distinct device, heterogeneous networks technology, can not satisfy the test of multiple complex scene.
Summary of the invention
The purpose of this invention is to provide the simulation method of protocol stack in a kind of mobile communication, can improve the protocol stack simulation efficiency, by the various combination of existing module, the distinct interface of simulation different system is initiated operational trials.
For this reason, the present invention has adopted following technical scheme: the simulation method of protocol stack in the mobile communication, it is characterized in that: the protocol stack of mobile phone terminal is divided into upper-layer service application protocol stack and bottom network element bearing protocol stack, segment and encapsulate with modularity respectively, according to test needs independent assortment and stack.
The present invention has utilized reconfigurable bimodulus multi-protocol stack technology, is a kind of simulation method of protocol stack towards network element, can provide modular many interfaces adaptive tenability on single test macro; Can realize the test request that many interfaces insert, realize the independence of test service structure, script control and testing hardware interface type, make that system applies is more convenient, flexible, safety.

Embodiment
Referring to accompanying drawing.Present embodiment relates to 2.5G and 3G mobile communication network.Because both core net have adopted the different bearer interfacing to wireless access network, after the ATM cell of the FR frame of being finished Gb Interface by the testing module hardware and Iu-ps interface is handled, each the bearing protocol stack of PCU (RNC) and the various service applications protocol stack of mobile phone terminal all utilize software engineering to realize on the generic server hardware platform, and multi-mode tenability, the shared ability of multi-service protocol stack flexibly are provided.
2.5G and the upper layer application service protocol of 3G mobile terminal is basic identical, is details aspects such as professional Control Parameter, mobile phone terminal ability parameter and resource and parameter distribution function differences to some extent.During technology realizes, with SNDCP and GTP-U layer is the boundary, the different bearing protocol mode of bottom be packaged into one by parameter select control, to the transparent unified interface platform in upper strata, shield different bearing bed technological disparity, as the ISP on upper strata, the various application protocols on the mobile phone terminal can be selected by SDNCP or GTP-U layer packing bearing message according to type, the scene mode of mobile phone terminal.Such design makes definite functions between each layer, and interface is clear, for the function expansion, use to increase successively flexibility is provided, helps the realization of concrete programming.
Each bearing protocol layer total difference is bigger in Gb Interface and the Iu-ps interface, but still has certain succession similarity at aspects such as message encapsulation unsealing operation, state machine migration, context and timer managements.Technology is divided into general and special part with every layer protocol function in realizing.By the functional module parametrization with extract to inherit the protocol stack general portion decomposition method successively that grades, with the different agreement layer at protocol function, protocol infrastructure, data structure, protocol frame and consultative management aspect extract corresponding general utility functions, on the basis of the abstract set of general utility functions and unified Modeling, provide abstract to the layer of service application and the terminal type and the network equipment, and increase and to stride the stack management and to reshuffle management function and finish and comprise state transition, strategy provides, service management etc. with reshuffle relevant task, reach the purpose that each layer of protocol stack reshuffled flexibly.
In addition, because the needs of test bimodule service performance of handoffs also will be considered complicated factors such as protocol stack is synchronous, the separation of signaling user plane during technology realizes.Present embodiment provides management 2G and the concurrent ratio of 3G mobile terminal traffic simultaneously, adapts to the test of multiple complex scene.
As seen, present embodiment has remedied the influence that existing protocol stack emulation mode is developed by type of service, interface type, take reconfigurable bimodulus multi-protocol stack technology, realize dynamic dispatching management GPRS and TD-SCDMA mobile phone terminal service concurrence ratio, shared service testing ability and do not waste the existed system investment, can adapt to the test of multiple complex scene.
