If UE need directly visit Internet by AP, at first need AP to network, thereby introduce the access point method of network entry that the embodiment of the invention provides earlier:

Fig. 1 has described the flow process of access point method of network entry embodiment one provided by the invention, comprising:

Whether step 101, the transmission first access point group are surveyed (Group Detect) message detection local area network (LAN) has the access point group to exist;

Access point needs to network, thereby can send the first access point group probe message after powering up the initialization success; Wherein, access point group probe message can be broadcasting or a multicast message etc. in the local area network (LAN);

Step 102, judged whether that according to the result of detection of the first access point group probe message access point group exists; If not, enter step 103; If enter step 104;

If there is the access point group to exist, then can receive the response message of response access point group probe message; If do not receive response message, then explanation does not have the access point group to exist.

Step 103, notice AP network management unit local area network (LAN) do not have the access point group to exist, and triggering the AP network management unit is that local area network (LAN) distributes the first access point group id, sets up the corresponding relation of the access point and the first access point group id; Process ends;

Set up the corresponding relation of access point and access point group id, can be used for AP Topology Management, UE agency's MAC Address management etc.Wherein, the AP network management unit is after local area network (LAN) distributes the first access point group id, the first access point group id that distributes can be sent to corresponding access point, thereby make access point can know the first access point group id that the AP network management unit distributes.

Step 104, obtain the second access point group id of the access point group of existence, trigger the corresponding relation that the AP network management unit is set up the access point and the second access point group id; Process ends.

Concrete, if there is the access point group to exist, the response message of the response access point group probe message that then receives can carry the corresponding second access point group id, thereby can from response message, obtain the second access point group id, after having obtained the second access point group id, just can send and trigger the corresponding relation that message trigger AP network management unit is set up the access point and the second access point group id, the wherein sign that in triggering message, can carry the second access point group id and access point to the AP network management unit.Wherein, the embodiment of the invention does not limit the particular type that triggers message, as long as can carry the realization that the sign of the second access point group id and access point can not influence the embodiment of the invention.

From the above, can make AP obtain the access point group id, and then use the access point group id that obtains to network by present embodiment; Thereby make UE obtain the network address, and then make the UE that obtains the network address directly visit Internet, AP is effectively used, improve system's utilization ratio by this AP by this AP that networks; Because the mobility of AP is strong, can makes the user obtain better Internet and experience, and directly visit Internet simultaneously, can not take the resources of core network of communication network, reduce taking limited resources of core network by AP.

Wherein, after the mode that access point is provided by access point method of network entry embodiment one networked, the access point method of network entry that the embodiment of the invention provides can also comprise:

Reception is from the second access point group probe message of other access points; Whether other access points send second probe message and are used for surveying local area network (LAN) and have the access point group to exist.

Send the first access point group id or the second access point group id to other access points that send the second access point group probe message; Wherein, judge when not having the access point group to exist in step 102, transmission be the first access point group id; Otherwise what then send is the second access point group id.Because after access point method of network entry embodiment one described flow process, corresponding access point networks, its corresponding access point group id can be the first access point group id or the second access point group id, thereby can be after receiving the second access point group probe message, send the access point group id of self correspondence to other access points of correspondence.Send the processing load that the access point group id can reduce the AP network management unit by access point.

Further, before sending the first access point group id or the second access point group id, the access point that sends the second access point group probe message may further include following steps:

Determine transmitting time at random;

If, then do not send the first access point group id or the second access point group id to the access point that sends the second access point group probe message receiving the access point group probe response that sends to the access point that sends the second access point group probe message in the transmitting time at random; If, then send the first access point group id or the second access point group id to the access point that sends the second access point group probe message not receiving the access point group probe response that sends to the access point that sends the second access point group probe message in the transmitting time at random.

After in system, having a plurality of AP to have corresponding access point group id, definite transmitting time is at random also sending the access point group id after the transmitting time at random, because the transmitting time at random of each access point all is to determine at random, thereby the transmitting time at random of each access point can be not identical, can avoid having in the local area network (LAN) a plurality of AP to respond simultaneously causing the response storm thereby send the access point group id after transmitting time at random.Wherein, the embodiment of the invention does not limit definite method of transmitting time at random, for example can adopt the algorithm computation that presets transmitting time at random.

Step 202, an AP do not receive access point group response message, send the request of access point group id to the AP network management unit;

Wherein, the embodiment of the invention does not limit the particular type of access point group id request, and any message that can make the AP network management unit distribute the access point group id can not influence the realization of present embodiment.

In the present embodiment, suppose that the request of access point group id is AP registration (AP Register) message, can identify in the AP registration message oneself is first AP in the net, thereby impel the AP network management unit to distribute the access point group id, also can in the AP registration message, directly carry the information of request AP network management unit distribution access point group id etc.

Step 203, AP network management unit are an AP place network allocation access point group id.

The AP network management unit according to sign (AP is that first AP or the request in the network distributes access point group id etc.) wherein, is an AP place network allocation access point group id behind the AP registration message that has received AP transmission.

Wherein, after being an AP place network allocation access point group id, can set up the corresponding relation of the AP sign of an access point group id and an AP simultaneously, for AP Topology Management and UE agency's MAC Address management.

Step 204, AP network management unit send AP registration response (AP Register Ack) message to an AP, and this message is included as the AP network management unit sign of the access point group id and the AP network management unit of AP place network allocation.

Step 205, an AP use the access point group id in the AP registration response to network; Can write down simultaneously the access point group id uses in order to the group probe response of the new AP of adding in the follow-up net.

Step 206, the 2nd AP send the existence that AP group probe message is surveyed the AP group.

After step 207, an AP receive the AP group probe message that the 2nd AP sends, calculate at random the transmitting time value and avoid responding storm; If in waiting for transmitting time, receive the probe response of broadcasting group, do not send the probe response of access point group to an AP; Otherwise, if transmitting time arrives at random, sending access point group probe response (Group Id Response) message, this message comprises the access point group id, thereby makes the 2nd AP can use this access point group id to network.

Fig. 3 has described the flow process of access point method of network entry embodiment three provided by the invention, comprising:

Whether step 301, transmission first access point group probe message detection local area network (LAN) have the access point group to exist;

Step 302, judged whether that according to the result of detection of the first access point group probe message access point group exists; If not, enter step 303; If enter step 304;

The first access point group id of step 303, generation local area network (LAN) triggers the corresponding relation that IAD is set up the access point and the first access point group id; Process ends;

If do not receive the access point group probe response of the response first access point group probe message, then self claims the first access point group id according to the access point group generating mode that presets.Wherein, the embodiment of the invention does not limit the mode that generates the first access point group id, is the unique realization that can not influence the embodiment of the invention of the overall situation as long as can guarantee the first access point group id that generates; For example, can adopt the mode of AP sign+timestamp to generate the first access point group id;

Step 304, obtain the second access point group id of the access point group of existence, trigger the corresponding relation that IAD is set up access point and the described second access point group id; Process ends.

This step is carried out with reference to step 104.

Further, the access point method of network entry embodiment three that provides of the embodiment of the invention can also comprise the steps:

Send the first access point group id or the second access point group id to other access points that send the second access point group probe message.Wherein, judge when not having the access point group to exist in step 302, transmission be the first access point group id; Otherwise what then send is the second access point group id.Because after access point method of network entry embodiment three described flow processs, corresponding access point networks, its corresponding access point group id can be the first access point group id or the second access point group id, thereby can be after receiving the second access point group probe message, send the access point group id of self correspondence to other access points of correspondence.Send the processing load that the access point group id can reduce the AP network management unit by access point.

Further, before sending the first access point group id or the second access point group id, the access point that sends the described second access point group probe message may further include following steps:

Determine transmitting time at random;

If, do not send the first access point group id or the second access point group id to the access point that sends the second access point group probe message receiving the access point group probe response that sends to the access point that sends the second access point group probe message in the transmitting time at random; If, send the first access point group id or the second access point group id to the access point that sends the second access point group probe message not receiving the access point group probe response that sends to the access point that sends the second access point group probe message in the transmitting time at random.After transmitting time at random, send and cause the response storm in the time of to avoid having in the local area network (LAN) a plurality of AP to network.Wherein, the embodiment of the invention does not limit definite method of transmitting time at random, for example can adopt the algorithm computation that presets transmitting time at random.

Step 403, an AP send the AP registration message to the AP network management unit, the access point group id that sign generates in registration message; Trigger the AP network management unit and set up the corresponding relation of access point group id and AP sign, for AP Topology Management and UE agency's MAC Address management.

Step 404, AP network management unit send the AP registration reply message to an AP.

Step 405, the 2nd AP send the existence that AP group probe message is surveyed the AP group.

After step 406, an AP receive AP group probe message, calculate at random the transmitting time value and avoid responding storm; After in waiting for transmitting time, receiving the probe response of broadcasting group, do not send the probe response of access point group to an AP; Transmitting time arrives at random, sends access point group probe response message, and this message comprises the access point group id, thereby makes the 2nd AP can use this access point group id to network.

Fig. 5 has described the flow process of the access point method of network entry embodiment five that the present invention also provides, and present embodiment is described to such an extent that be the handling process of AP network management unit, comprising:

Step 501, the request of reception access point group id, the request of access point group id is sent by access point, and the request of access point group id comprises the access point identity of the access point that sends this access point group id request;

Access point just can send the request of access point group id after connecing electric initialization, by sending the access point group id acquisition request access point group id corresponding with self;

The access point group of step 502, inquiry access point identity ownership is obtained the access point group id of access point group;

Wherein, can be in advance with the access point grouping, the AP network management unit can be preserved the corresponding relation of each access point identity and access point group id, after having obtained access point identity, just can obtain corresponding access point group id;

The access point group id that step 503, transmission are obtained.

After having sent the access point group id that obtains, the access point that sends the request of access point group id just can get access to the access point group id, and then networks by this access point group id.

After access point method of network entry embodiment that AP provides by the embodiment of the invention networked, UE just can be by the networking of the AP after networking, and then can directly visit Internet by AP, followingly introduced the subscriber equipment method of network entry that the embodiment of the invention provides again:

Fig. 6 has described the flow process of subscriber equipment method of network entry embodiment one provided by the invention, description be UE by the handling process that AP goes into AP in the network process, comprising:

Step 601, reception network address request;

Wherein, network address request is sent by UE, and network address request comprises the UE sign of the UE that sends this network address request;

The activation PDP request message that network address request sends in the time of can being UE initiation packet data protocol (PDP:Packet Data Protocol) activation process also can be after having activated PDP, and UE initiates PPP flow process or message that the DHCP flow process sent etc.;

Step 602, obtain and MAC Address that UE sign is corresponding;

Wherein, if activate the PDP request message, be designated UE according to UE and obtain the network address and take a step forward and comprise: judge whether described activations PDP request message comprises that direct access identities and packet data protocol type are that the Internet protocol and the network address are not sky; If then obtain and the corresponding MAC Address of UE sign; If not, handle to activate the PDP request message according to presetting processing mode, for example do not comprise direct access identities, show that then UE directly visits Internet by AP, can handle this moment according to the processing mode of directly not visiting Internet by AP.

Wherein, the following flow process that specifically can adopt the embodiment of the invention to provide is obtained and the corresponding MAC Address of UE sign:

Using UE sign and access point group id to initiate MAC Address to the AP network management unit rents, the AP network management unit takes out still untapped MAC Address in the access point group of access point group id correspondence from the MAC Address pond, the MAC Address that the MAC Address that the AP network management unit is chosen is and the UE sign is corresponding.

Can also use the UE sign to generate MAC Address according to the MAC Address generating algorithm that presets, a kind of MAC Address generating algorithm that the embodiment of the invention provides be as described below:

Table 1 is depicted as the content of each bit in MAC Address first byte:

Table 1

7?

6?

5?

4?

3?

2?

1?

0?

U/L?

I/G?

Wherein I/G=0 identifies unicast address (INDIVIDUAL ADDRESS); I/G=1 identifies multicast address (GROUP ADDRESS); U/L=0 identifies global management address (GLOBALLYADMINISTERED ADDRESS); U/L=1 identifies local management address (LOCALLYADMINISTERED ADDRESS);

Bit 0 sign unicast address or multicast address, the embodiment of the invention can be used unicast address;

Bit 1 sign is the address of local management or whole world management, and the embodiment of the invention can be used local management.

When generating MAC, I/G bit perseverance is zero, and the U/L bit is 1; Other bit settings only need prevent that the first byte numerical value of constructing from conflicting with AA; The actual available value of first byte is 63 so; MAC Address first byte is used this 63 values, can guarantee the uniqueness in the whole world.

Five remaining bytes are carried out binary decimal system (BCD) compressed encoding according to ten numerals of low level of mobile subscriber's ISDN(Integrated Service Digital Network) number (MSISDN) or international mobile subscriber identity (IMSI); If the outcome conflict behind the coding uses first byte to carry out collision avoidance so, can solve the card of 63 conflicts at most.For example: MSISDN 13904356789, and the MAC that constructs according to the above-mentioned value principle of the first byte numerical value can be 02-39-04-35-67-89.

Wherein,, after generating MAC Address, can in net, whether use be arranged this MAC of broadcast probe for the MAC Address that prevents to generate has conflict, if use, then with the first byte conversion numerical value of MAC Address, maximum available 63 numerical value.

Step 603, use MAC Address to obtain the network address as UE;

Concrete, if the network address is Internet protocol (IP:Internet Protocol) address, then can obtain the above-mentioned network address by dhcp process, for example, can be that UE obtains the network address by the DHCP flow process directly according to the UE sign;

Can after adopting the UE sign to rent MAC Address, be that UE obtains the network address by the DHCP flow process also, wherein, specifically can rent MAC Address from the access point network administrative unit according to the MAC Address of renting.

Wherein, when obtaining the network address by the DHCP flow process, can further write down the DHCP protocol information, thereby when UE carries out switching between AP, the DHCP protocol information of record can be sent to the AP that UE switches to, the AP that UE is switched to can obtain corresponding D HCP protocol information.

After having obtained the network address, can initiate free address resolution protocol (ARP:AddressResolution Protocol) message, refresh the forwarding-table item of two-layer equipment in the network, make the information that sends the network address that UE most obtains correctly to be sent to UE.

The network address that step 604, transmission are obtained.

Specifically be to send the network address that obtains, thereby make this UE obtain the network address, and then network by this network address to the UE that sends network address request.

Wherein,, then can the network address that obtain be sent to UE, before sending activation PDP response message, need the empty port load-supporting (Radio Bearer) of foundation and UE by activation PDP response message if network address request is activation PDP request message; Also can the network address that obtain be sent to UE by revising PDP Context (Modify PDPcontext) message.If network address request is not to activate the PDP request message, can the network address that obtain be sent to UE by revising PDP Context message.

From the above, after AP networks, use present embodiment can make UE obtain the network address by the AP that networks, make UE can use this network address access network, thereby make UE directly visit Internet by AP, and AP is effectively used, improve system's utilization ratio; Because the mobility of AP is strong, can makes the user obtain better Internet and experience, and directly visit Internet simultaneously, can not take the resources of core network of communication network, reduce taking limited resources of core network by AP.

Fig. 7 has described the signaling process of subscriber equipment method of network entry embodiment two provided by the invention, has described activation PDP flow process, comprising:

Step 701, UE send to AP and activate the PDP request message; Can carry the AP sign of AP in this request message;

Further, if UE wants directly to visit Internet by AP, can comprise APN (APN:Access Point Name) in activating the PDP request message, sign UE directly visits Internet by this AP; Being understandable that, comprising that in activating the PDP request message it only is a kind of implementation that the embodiment of the invention provides that APN sign UE directly visits Internet by this AP, is not to limit the embodiment of the invention only can adopt this kind mode.

Whether step 702, AP identification comprise APN;

If comprise APN then illustrate that UE passes through AP and directly visits Internet;

Wherein, can judge further as required whether the PDP type is that IP and address entries are not empty.
