Description
Technical field
The present invention relates in moving communicating field, particularly relate in CN group net and support many Flex passage software terminal and self adaptation dynamic access method thereof.
Background technology
Software terminal is positioned at the communication applications software on fixing or mobile device, is the infrastructure of access CN group net.
Flex passage realizes software terminal and CN(CoreNetworks) technology that is connected of group's net height, Flex passage framework on network layer, when observing SIP(SessionInitiationProtocol) consensus standard utilize relevant field to carry connection and switching that effective information realizes software terminal and CN group's major network.
Software terminal only sets up a Flex passage to CN group net when starting, when CN group net fault or network congestion, software terminal will can not get the response of CN group net or just obtain the response of CN group net after postponing a period of time, and this has had a strong impact on quality and the efficiency of information interaction.
In addition, software terminal just detects local logical address when starting, and this situation have ignored the possibility that local logical address dynamically changes.Under actual application environment, due to the impact of mobility, signal intensity and the objective factor such as artificial, the logical address of software terminal this locality can change.The change of software terminal logical address will make the successful user of earlier registration cannot carry out normal mutual with CN group net, and software terminal communication will be failed, can only carry out new registration and information interaction by restarting software terminal.
In the prior art, software terminal is only passing through when starting the information interaction that a Flex passage realizes and CN group nets, and in the process of information interaction, adopts many Flex passage.Software terminal only detects CN group net and distributes to local logical address when starting, do not have the local logical address of detection of dynamic and make corresponding adjustment.
Summary of the invention
The object of the invention is, for solving the problem, proposing a kind of support many Flex passage software terminal and self adaptation dynamic access method thereof.Technical solution of the present invention is, software terminal is when starting, and local logical address distributed to by physical layer interface unit inspection CN group net, and gives software terminal core cell by this logical address.Local logical address is saved in buffer memory by core cell, and based on this logical address, initiates information interaction by CN interface unit to CN group net.CN interface unit is responsible for and CN group net between packets of information receive and send, realize CN group over-network registration user and to engage in the dialogue function.
Support many Flex passage software terminal of the present invention, it comprise software terminal, with software terminal match operating system, CN group net and be communicated with the wired or wireless passage that operating system and CN group net.Described software terminal is provided with the CN interface unit, core cell, the physical layer interface unit that connect successively.
The dynamic access method of support many Flex passage software terminal of the present invention, comprises the steps:
Step 1, software terminal physical layer interface unit run timing device T, timer T detects the current logical address that software terminal distributed to by CN group net when triggering each time;
Step 2, software terminal underlying operating system is responsible for safeguarding current logical address, and the logical address that recapture is new when current logical address lost efficacy;
Step 3, the local logical address detected first is passed to core cell by software terminal physical layer interface element timer T, timer T continues to detect the current logical address that software terminal distributed to by CN group net: when detecting that current logical address sends change, new current logical address is passed to software terminal core cell by physical layer interface unit; When detecting that current logical address does not change, physical layer interface unit does not do any process;
Step 4, when software terminal core cell receives the new logical addresses passed over by physical layer interface unit each time, new current logical address information is saved in buffer memory by core cell, and suspend the process that all send packets of information immediately, enter address synchronization process by Option message informing CN group net, software terminal is local also enters address synchronization process simultaneously simultaneously;
Step 5, after not having address synchronization process or address synchronization process to complete, packets of information according to local information and the relevant good packets of information of CN group network server Information encapsulation, and is sent to CN server from CN interface unit by software terminal core cell, completes relevant task;
Step 6, all software terminal of software terminal CN interface unit handles and CN group net packets of information mutual.
Many Flex passage bridge process schematic of the present invention, software terminal and CN group net reciprocal process adopt many Flex passage:
Step 1, after software terminal starts, software terminal and main CN server carry out the demand that packets of information realizes various user alternately.Meanwhile, main CN startup of server timer continues to send Option message to software terminal.The relevant field notice software terminal CN server address for subsequent use of main CN server by utilizing Option message.According to network burden size, CN group net is that software terminal configures several CN servers for subsequent use.
Step 2, when main CN server failure or network condition not good time, software terminal cannot obtain or for a long time just obtain the response of main CN server.At this moment, software terminal hangs up current user task, and time-out is mutual with CN master server.
Step 3, software terminal selects a CN server address for subsequent use, software terminal enabling address synchronizing process, replaces previous main CN server address with CN server address for subsequent use, and initiatively send Option message to this CN server for subsequent use, notify this CN startup of server address synchronization process for subsequent use.
Step 4, software terminal and CN server completion logic address for subsequent use and inter-related task synchronizing process, the local logical address of respective realization and the renewal of the other side's logical address in all user-level task, the hang-up point that software terminal and CN server for subsequent use return being suspended separately of task continues to run.
The advantage of the dynamic access method of many Flex passage software terminal of the present invention is:
1) software terminal current C N server failure or current Flex passage congested time, be initiatively established to the Flex passage of CN standby server, current registered user is unaffected with communicating of this user.
2) software terminal in use dynamic monitoring CN group net distribute to local logical address, change once monitor local logical address, first software terminal will re-register active user, make CN group net and this locality all use new logical address to carry out information interaction, current communication is by unaffected.
3) CN group net provides master server and several times server for software terminal, master server and time server is all preserved the effective information of active user, for many Flex passage of software terminal provides support.
4) communication quality of software terminal and CN group net or can not be worked as channel congestion and reduce because of the fault of software terminal current C N server; The advantage proposing software terminal self adaptation dynamic access technology is that software terminal can not stop present communications because of the change of local logical address or restart, and greatly improves communication quality and the reliability of software terminal.
