Embodiment
Execution mode 1
Fig. 1 is the figure that the network configuration of embodiment of the present invention 1 is shown.The following structure of network using: radio base station apparatus 100 is selected successively via the path of BBR (broadband router) 200 and ISP400 or via the path of the PPPoE server 300 of ISP 400, be connected with the Internet 600, communicate via the router 700 and the epigyny device 500 of relative configuration.
Radio base station apparatus 100 be and mobile communication terminal between carry out the device of radio communication, have: wireless signal received send the reception sending part 101 handled, carry out wire signal as the interface of network side and receive the network interface portion 102 that sends relevant treatment and control the control part 103 that wireless reception sends and wired reception sends.Control part 103 has the data store 104 of storage wired connection desired parameters.The transmission blanking time, number of times of authentication mode that PPPoE connects, ID (identifier), password, keep-alive and overtime time bar, the retry interval time when Dynamic Host Configuration Protocol server does not connect, number of times and overtime time bar etc. are arranged in the desired parameters.
Epigyny device 500 is for example can carry out the control of radio base station apparatus 100 or carry out the upper node of the radio base station apparatus 100 of packet switching.
Fig. 2 is the flow chart that the handling process of radio base station apparatus is shown.At first, in step a1, radio base station apparatus 100 starts by connecting or restarting power supply.In case start the PPPoE connection processing of promptly in next step a2, carrying out, so that carry out connection based on the 1st connected mode (for example PPPoE connected mode) to the PPPoE server.Particularly, the PPPoE server is sent the connection request that comprises the granting request of IP address, and wait for response from the PPPoE server.Then, in step a3, judging has the response that does not have from the PPPoE server.If response is arranged, then proceed to next step a4, still carry out obtaining based on the IP address that PPPoE connects, connect IP network, the state that formation can be communicated by letter with epigyny device 500.
If the PPPoE server is response not, or under situation overtime behind the retry, carries out the DHCP connection processing to Dynamic Host Configuration Protocol server in step a5, so that carry out the 2nd connected mode (for example DHCP connects).Particularly, Dynamic Host Configuration Protocol server is sent the connection request that comprises the granting request of IP address, and wait for response from Dynamic Host Configuration Protocol server.Then, among the step a6, judging has the response that does not have from Dynamic Host Configuration Protocol server.If response is arranged, then proceed to next step a7, still carry out obtaining based on the IP address that DHCP connects, connect IP network, the state that formation can be communicated by letter with epigyny device 500.
Under not from the situation of the response of Dynamic Host Configuration Protocol server or under situation overtime behind the retry, think that the PPPoE connected mode all can not be connected with the DHCP connected mode, returns the processing of step a2.The processing of execution in step a2, a3, a5, a6 repeatedly is until being connected with in the DHCP connected mode any with the PPPoE connected mode.
Carry out connection by utilizing such step to IP network, even unclear connected mode to IP network is under PPPoE or the situation of DHCP when starting radio base station apparatus, also can also carry out connection automatically in radio base station apparatus setting IP address to IP network.
Moreover, when Dynamic Host Configuration Protocol server does not respond, also can carry out based on be followed successively by the 3rd connected mode, the 4th connected mode ... the connection of IP network of different connected modes.
At first implement the reasons are as follows of PPPoE.Dynamic Host Configuration Protocol server usually is the broadband router in user's residence, the next localized network that is formed in user's residence inner sealing of broadband router in the case.Here, connect, then only to being that broadband router in user's residence of Dynamic Host Configuration Protocol server is propagated the PPPoE connection message if when being in the DHCP connection status, implement PPPoE.Broadband router abandons this PPPoE connection message as not clear message.Therefore, do not send to upper network.Like this,, do not influence ISP (ISP) at user's residence inner sealing.Therefore, be connected to good at first to implement PPPoE.
Above-mentioned is at first to implement PPPoE to connect preferable example, connects preferable and carry out DHCP earlier under ensuing situation.For example in the residence of condo, wait and be provided with under the situation of a plurality of radio base station apparatus 100, as shown in Figure 3, in the next direct-connected structure with a plurality of radio base station apparatus 100 and PPPoE server 300, cost corresponding to the connection expense that is connected radical of PPPoE server 300, cost rises.At this point, as shown in Figure 4, by insert broadband router 200 between PPPoE server 300 and the next a plurality of radio base station apparatus 100, the next regional area that becomes of broadband router 200 does not spend the connection expense to ISP (ISP).Only spend the expense that is connected between broadband router 200 and the PPPoE server 300, favourable aspect cost.Under the situation that is in such type of attachment, connect by carrying out DHCP earlier, can shorten the time of Wireline connection processing.
Execution mode 2
Fig. 5 is the figure of structure that the radio base station apparatus of embodiment of the present invention 2 is shown.Present embodiment 2 is added wiring line state test section 105 and resume storage part 106 in the radio base station apparatus of execution mode 1.
Identical with execution mode 1, data store 104 also is included in the storage device in the control part 103, and storage starts the required system parameters of radio base station apparatus 100.Resume storage part 106 is included in the storage device in the control part 103 equally, is made of nonvolatile memory, and storage connects the resume of IP network success or failure with which mode of multiple connected mode (for example PPPoE or DHCP).When radio base station apparatus 100 starts, call the system parameters of storage in the data store 104, attempt connecting IP network with the specified Starting mode of this system parameters (for example PPPoE or DHCP).Thereafter, the connected mode (for example PPPoE or DHCP) with successful connection records resume storage part 106 successively.If there is the actual achievement that is connected with IP network, even once, also record this resume storage part 106, accumulate connecting resume like this.
Line status test section 105 is included in the network interface portion 102, monitors the state of the circuit of foundation at ordinary times via IP network.The state of circuit refers to the state that circuit that circuit has cut off or cuts off obtains restoring.If line status test section 105 detects line status (cutting off or recovery), the then state that immediately control part 103 announcement trunks is cut off or restore.When detecting circuit when cutting off, make the LED that is arranged at radio base station apparatus 100 (Light Emitting Diode: light-emitting diode, not shown) lighting, thereby the operator is alarmed corresponding to the form of circuit dissengaged positions.When detecting circuit when restoring, restored and the form that forms user mode is lighted LED with the expression circuit.
At this moment, according to the resume of the connected mode of storage in the resume storage part 106, the connected mode (for example PPPoE or DHCP) of cutting off eve with circuit reconnects Internet connection.
Fig. 6 is the flow chart of the control part handling process when the circuit recovery is shown.Under the state that Wireline cuts off, at first in step b1, line status test section 105 detection lines of network interface portion 102 restore.Then, in step b2, if receive the notice that circuit restores, then pass through with reference to resume storage part 106, the connected mode of confirming circuit cut-out eve is which kind of (for example being PPPoE or DHCP) in the multiple connected mode.Then, in step b3, judge which kind of connected mode is the connected mode of circuit cut-out eve be.
If the connected mode of circuit cut-out eve is PPPoE in step b3, then proceed to next step b4.In step b4, the keep-alive timer PPPoE server that expires is not implemented to cut off and is handled when judging whether to restore because of circuit.Here, if the keep-alive timer expires, after promptly surpassing, in next step b5, be judged as by the PPPoE server and cut off and being connected of IP network, and carry out reconnecting based on PPPoE.
Among the step b4,, then proceed to step b6 if the keep-alive timer of PPPoE is not yet due.In step b6, the echo request of using with keep-alive (EchoRequest) sends at interval irrespectively to the request of PPPoE server transmission echo.This is that pppoe session is effective when confirming irrespectively that with the interval of keep-alive circuit restores.In next procedure, judge to have and do not reply (EchoReply) from the echo of PPPoE server.If have from the echo of PPPoE and reply, then proceed to next step b8.In step b8, pppoe session also in setting up process, continues PPPoE and connects.
If do not reply from the echo of PPPoE server in step b7, then being judged as does not have the PPPoE server, and connected mode changes DHCP into, and the DHCP connection processing that starts anew in step b9.
Thus, can not wait for the keepalive period of PPPoE, change the processing of connected mode after circuit restores immediately.
It is also identical when in addition, the connected mode of circuit cut-out eve is DHCP.
When the connected mode of circuit cut-out eve is DHCP in step b3, proceed to step b10.In step b10, judge whether the DHCP lease timer expires.Whether expire according to the DHCP lease timer, can judge whether Dynamic Host Configuration Protocol server is opened DHCP and connected.Here, if the DHCP lease timer has expired and promptly surpassed, then be judged as Dynamic Host Configuration Protocol server and discharged the DHCP connection, thereby carry out reconnecting based on DHCP.
In step b10,, then in next step b11, irrespectively Dynamic Host Configuration Protocol server transmission DHCP is asked at interval with the transmission of DHCP request if the DHCP lease timer is not yet due.Whether this is still effective based on the IP address of DHCP when confirming that irrespectively circuit restores at interval with the transmission of DHCP request.Then in step b12, judge whether that returning DHCP from Dynamic Host Configuration Protocol server confirms (DHCP ACK).Confirm that then the IP address is still effective if return DHCP, in next step b13, continue DHCP and connect from Dynamic Host Configuration Protocol server.
Do not confirm that then be judged as connected mode and change PPPoE into, and proceed to step b5, the PPPoE connection processing starts anew if in step b12, return DHCP from Dynamic Host Configuration Protocol server.
Thus, the cycle of renting prolongation of DHCP can be do not waited for, the processing of connected mode can be changed after circuit restores immediately.
Equally, the recovery behind dump or when restarting restarting of causing after also resume storage part 106 being confirmed, at first reconnects with identical connected mode.
Utilize above execution mode, obtain to shorten recovery after Wireline cuts off or the recovery behind the dump, the effect of the connection processing time when restarting reconnecting of causing.
Execution mode 3
When the control part 103 of radio base station apparatus 100 does not have from the response of server,, stop connection processing through behind certain certain hour after sending connection request, promptly overtime.In above-mentioned execution mode 1 or 2, specify overtime time bar with the system parameters of storage in the data store 104 of control part 103.In present embodiment 3, the relevant turnaround time of connected mode that the past was connected is stored in the time storage part (not shown) of control part 103 in advance, and according to the overtime time bar of this turnaround time setting.The time storage part is identical with resume storage part 106, is made of nonvolatile memory, also can be shared with resume storage part 106.Turnaround time be from send connection request, to receiving time from the response of server corresponding to this connection request.
The action of present embodiment 3 then is described.After radio base station apparatus 100 was for example pressed PPPoE or DHCP startup, the turnaround time during with connection number of times and startup was stored into respectively in resume storage part 106 and the time storage part.According to connecting number of times (connection resume) and turnaround time when being connected can be calculated the mean value of turnaround time, and should value also be stored in the time storage part in advance.
When the Wireline dissengaged positions restores, utilize resume storage part 106 to confirm that circuit cuts off the connected mode of eve, and reconnect processing, wherein the time set that will set based on the turnaround time of storing in the time storage part is overtime time bar.For example, with 2 times of times to the turnaround time as overtime time bar.Perhaps, storing for a kind of connected mode under the situation of a plurality of turnaround time, with 2 times of times to its mean value as overtime time bar.If passed through the response that also not to have the time from server, just carried out connection processing with other connected mode.
This behind dump recovery or restart after to reconnect when action also identical.
Utilize above execution mode, can the mode of being connected change recovery after Wireline cuts off or the recovery behind the dump, the connection processing time when restarting reconnecting of causing, can connect rapidly.
Execution mode 4
Fig. 7 is the figure of structure that the radio base station apparatus of embodiment of the present invention 4 is shown.In execution mode 1,2 or 3, when radio base station apparatus 100 starts or when reconnecting, when IP network is connected, attempt multiple connected mode (for example connecting or the DHCP connection) successively from PPPoE, but in the present embodiment 4, (for example PPPoE is connected and be connected both) trial concurrently simultaneously for multiple connected mode and connect with DHCP.For this reason, control part 103 comprises the 1st connection processing portion 107 and the 2nd connection processing portion 108 that carries out based on the connection processing of DHCP connected mode that carries out based on the connection processing of PPPoE connected mode.
The action of present embodiment 4 then, is described.Radio base station apparatus 100 (comprises recovery or the recovery behind the dump after Wireline cuts off, restarts restarting of causing) when starting, and all attempts concurrently and being connected of IP network at PPPoE and DHCP two states.At this moment, carry out connection processing according to the indication of the system parameters of storage in the data store 104.For example, as from the response of PPPoE or a certain side's of DHCP server the time, use the connected mode corresponding to start and use with this server.In addition, in the moment that has had from the response of a server, stop the connected mode relevant connection processing corresponding with another server.For example, as during from the response of PPPoE server, 107 pairs the 2nd connection processing portion 108 announcement servers of the 1st connection processing portion have response, and the connection processing of the 2nd connection processing portion 108 is stopped.
Connected mode is that the situation more than 3 is also identical, at the server of first kind of connected mode moment of response has been arranged, and the connection processing of remaining connected mode is stopped.
Owing to carry out the different processing of connected mode as mentioned above like that concurrently, so, then needn't wait for to overtime for other connected mode if a kind of connected mode is connected.Thereby, shortened the effect of the time before connecting significantly.
