Embodiment
The contrast prior art is set forth the described technical scheme of the embodiment of the invention below.
At present can be for the user provide the network of service a lot, different networks has different pluses and minuses, and online network program (for example MSN) brings user's experience difference under the heterogeneous networks connected mode, can be embodied in network speed, stability, rate, fail safe etc.The network that wireless network program is selected in the face of plurality of optional connects, the user need be according to actual conditions and dynamically handover network connect, obtain higher user experience.
When prior art generally is instant communication client operation or login, mode by inquiry points out the user to select one as current access network in the network list that can insert, when the user need switch to other network or current network and can not support that current logging status is normally moved, can only interrupt the logging status of instant communication client in the current network, when switching to new network, send logging request to server again.Because MSN is to be the software of purpose with transmission information, in handoff procedure, interrupt its logging status, bring great loss to the user possibly, for example: transmit the file failure, the losing or the like of historical record.
Problem based on above-mentioned prior art existence, the invention provides method, instant communication client, management server and system that a kind of many networks switch, can connect according to the dynamic handover network of user's actual needs, and at domestic present wireless network situation, make the transitions smooth of instant communication client online logging status in network switching process and the close friend by reasonable manner, reach best user's sense.
The embodiment of the invention go for GPRS (cmnet, cmwap), 3G, the handoff procedure of main flow wireless network environments such as Wifi.
Below in conjunction with specific embodiment technical scheme of the present invention is further specified.
In conjunction with Fig. 1, the embodiment of the invention has proposed the method that the many networks of a kind of instant communication client switch with the angle of instant communication client, and technical scheme can comprise:
Step 102:, current network is switched to objective network when receiving the handoff request that the user sends or detecting current network when unusual;
Step 104: send the message that comprises predetermined sign to management server, described sign is used to represent and will continues operation to inform the logging status that management server remains in the current network in objective network from the logging status of the logging status converting into target network of current network.
Further, described method also comprises:
Step 101: when initial log or startup, the network-connectable tabulation that searches is offered the user, so that the user selects current network to insert;
More particularly, Fig. 2 supports that with one one the mobile phone of GPRS and two kinds of internetwork connection modes of WIFI is an example, illustrates that instant communication client is provided with the flow chart of current network when initial log or startup;
(1) instant communication client is judged network signal when initial log or startup, gets access to the network-connectable tabulation by mobile phone operating system API, and shows the user;
The user can be provided with the priority of network-connectable tabulation, and for example: the order according to signal strength signal intensity or network speed etc. is arranged.By the priority of disposing order of tabulation is set, when each instant communication client showed the user with described tabulation, the user can directly select in orderly tabulation, had saved the time of selecting.
Instant communication client can be by inquiry user's mode, determine when logining next time, whether to show the prompting of network-connectable tabulation, when the user selects not reresent after the selected current network that will insert connects, then preserve the network connection that the user selectes automatically, the network that acquiescence was preserved when each afterwards initialization connected inserts, and no longer inquires the user; Otherwise, when then next startup or login, still point out the user to carry out the selection that network connects.
(2) when the user selects the WIFI network as current access network, instant communication client can represent the WIFI signal source to the user according to the priority of signal power to be selected;
Because the WIFI network is different with the 3G network that GPRS or all kinds of operator provide, and has certain particularity, may there be the strong and weak different signal source of a plurality of signals in the WIFI network.So selected the user under the situation of WIFI network, the tab sequential of a plurality of signal sources by the signal power need have been represented to the user.
When the user selects rate type network to carry out network insertion, the explanation of the rate of correspondence is offered the user, so that the user selects the current network that inserts according to rate explanation intuitively, improve user experience;
(3) instant communication client inserts according to selected current network.
Further, step 102 specifically comprises:
When detecting current network and not supporting that current logging status is normally moved, current network is switched to the user in the tabulation of the handover network that provides in the selected objective network, perhaps, current network is automatically switched in the objective network of determining according to predetermined condition, perhaps, current network is automatically switched to the user according in the predefined objective network of experience effect;
Perhaps,
When receiving user's handoff request, current network is switched in the objective network that carries in the described request.
Further, described handover network tabulation can comprise:
Rate type network and corresponding rate explanation;
And/or, wireless broadband network and corresponding signal source list according to the signal strength signal intensity arrangement.
More particularly, for the handoff procedure of description of step 102, for instant communication client current network is switched to the flow chart of objective network with reference to Fig. 3;
Under the situation that login has connected, the user needs a continual and steady network that the service that provides is provided.In fact the current network environment changes probably, and for example: do not have network signal when the user enters elevator, perhaps the user leaves the network environment of WIFI etc.Do not adopting under the situation of the present invention, the user may face and go offline or can't use situations such as software.
Described technical scheme of the present invention switches to current network in the new objective network connection with the prompting user in the inner automatic recognition function of network environment that increases of instant communication client.
Automatically recognition function can comprise following content: when network A no signal or weak output signal cause Network Transmission at need, whether the prompting user selects signal network B preferably.If network B is the WIFI network, then initiatively point out out the WIFI access point that wherein signal is the strongest.
Described objective network is to determine in the following way:
(1) when detecting current network and do not support that current logging status is normally moved, the current network list that inserts of instant communication client search is prompted to the user, and the user selects the objective network that switches according to described network list;
More particularly, when the user does selection in above-mentioned scene, can add a reminder item, the prompting user whether objective network of current selection is set to acquiescence, when user's selection is, then not reresenting the current network insertion of user when then this scene occurring will switch next time, but directly finishes the dial-up connection work of new access point on the program backstage.
The rule of the available network that the user can also recognize automatically to instant communication client is done edit-modify.This mode is as follows: when instant telecommunication customer end detects current all access points that insert, provide options to allow the user can the sequencing of these access points be adjusted, the user can add does not in addition have detected access point.For example: add WIFI-A.Its relevant parameter is set then, afterwards this initiate access point is joined in the priority ordering of front.In case when entering the coverage of this access point, program can confirm whether needs are preferentially selected this network according to its current priority state.
(2) when detecting current network and do not support that current logging status is normally moved, but in the access network that searches, select best network as objective network, automatically current network is switched in the objective network and go according to predetermined condition; For example: but predetermined condition is according to signal strength values search access network, with the signal strength values maximum that searches as objective network;
Perhaps, current network is switched to the user according to the predefined objective network of experience effect; For example: when adopting rate type network, the user is an objective network according to the rate explanation network settings that rate are low, when satisfying switching condition, automatically current network is switched in the objective network;
(3) when receiving user's handoff request, current network is switched in the objective network that carries in the described request.
Because the not equal factor of the heterogeneous networks access point rate difference or the network bandwidth, even under the current available situation of network A, the user may also need to switch to network B, technical solutions according to the invention can offer the switching of an active of user and select the interface, make the user carry out active according to the experience of oneself and switch.
Further, described method can also comprise:
Step 103: by being kept at the operational factor in the current network in the internal memory in real time or writing mode in the file, be stored in the logging status in the current network, so that after switching to objective network, keep the logging status of current network to proceed.
More particularly, when instant telecommunication customer end in use needs the scene of handover network to occur, network before meaning connects and need rebulid, and management server will be redistributed the IP address of instant communication client, and software also will be logined again.At this moment of actions such as user's possibility WKG working and certain good friend chat or transmission file in current network, the present invention is in order to guarantee the user sense of instant communication client when network switches, adopt the current presence information of instant communication client of preserving in real time, for example: its buddy list state, parameters such as current interface state.In a single day be used for rebuliding successful connection with objective network, the action of carrying out before the user will continue to carry out without interruption.
Further, described predetermined sign sends to management server by heartbeat packet.
More particularly, Fig. 4 is instant communication client sends a flow chart from heartbeat packet to management server:
Heartbeat packet is meant instant communication client at regular intervals, and for example 60s sends a secondary data to management server, to keep the presence of instant communication client.When instant telecommunication customer end when current network is used objective network login management server instead, be equivalent to do once login again.Even bitcom at sequence of threads, in the process of this login, temporarily can't normally use the function of software as a kind of probably.In order to shorten the time interval that this is logined again, need provide a measure of login fast at the management server end.The method of this measure is as follows: instant communication client need send heartbeat packet one time at set intervals in order to guarantee the presence of oneself.When the user switch initiatively that other networks connect or current network to connect signal good and when using other networks automatically instead and connecting, in case objective network successful connection, instant communication client will send one have special identifier heartbeat packet to the management service end, this special identifier is that instant communication client and management server are made an appointment, when management server is received the heartbeat packet of this special identifier in the cycle of setting, can think that then instant communication client is the logging status of switching from the logging status of current network to objective network, rather than roll off the production line or go offline, management server continues the logging status of instant communication client in current network to go on automatically in objective network, and do not need instant communication client mutual with the login that management server is done after once going offline again, thereby accomplish in network switching process, seamlessly transitting of instant communication client logging status, make the imperceptible process that goes offline and reconnect that experienced under a lot of situations of user, improved user experience.
By the described method of above-mentioned specific embodiment, guaranteed the user experience of instant communication client in network switches, realized that instant communication client switches to the seamlessly transitting of logging status of objective network from current network, avoided going offline in network switching process instant communication client experience in the prior art, reduced the predicament of user experience.
