Below in conjunction with attached drawing, scheme provided by the embodiment of the present application is described in more detail.

With reference to Fig. 2 (a), it is register method flow chart provided by the present application, includes the following steps：

Step 201, terminal device send the first fixed network message to access device, and access device receives first fixed network and disappears Breath.

In first fixed network message include the first NAS message, the first NAS message be referred to as NAS login request message or Login request message etc., the first NAS message are registered to core net for requesting.

Step 202, access device send the first NAS message to the CP equipment of core net, and CP equipment receives the first NAS and disappears Breath.

After access device receives the first fixed network message of terminal device transmission, the first NAS message is sent to CP equipment, the One NAS message is used to be registered to core net to CP device request.

Step 203, CP equipment send NAS registration to access device and complete message, and access device receives NAS registration and completes Message.

CP equipment carries out the registration of core net to terminal device after the first NAS message for receiving access device transmission Process, if succeeding in registration, CP equipment sends NAS registration to access device and completes message, certainly, above-mentioned if registration failure Step 203 is replaced by step 203 (a), step 203 (a)：CP equipment sends NAS registration failure message to access device.

Step 204, access device send the second fixed network message to terminal device, and terminal device receives second fixed network and disappears Breath.

Access device sends the second fixed network to terminal device after message is completed in the NAS registration for receiving the transmission of CP equipment Message, the second fixed network message include the second NAS message, and the second NAS message is used to indicate registers kernel network and is completed.

If step 203 is substituted by step 203 (a), correspondingly, include in the second fixed network message sent in step 204 The second NAS message substituted by another NAS message, be used to indicate registers kernel network failure.

In above-mentioned steps, the interaction of terminal device and access device is wrapped in fixed network message by fixed network interacting message Containing NAS message, specifically, NAS message can be transmitted by manufacturer's self-defined information of fixed network message.To use PPPoE agreement For carrying out fixed network registration, if fixed network message is the message during pppoe session, pppoe session process can be used for example Link Control Protocol (Link Control Protocol, LCP) message in manufacturer's self-defined information transmit NAS message, I.e. LCP message is a fixed network message, carries NAS message in manufacturer's self-defined information therein, and such as above-mentioned first NAS disappears Breath, the second NAS message；Similarly, can also be come using manufacturer's self-defined information in the PPPoE message of PPPoE discovery procedure NAS message is transmitted, for example, adding the option (option) of customization type in PPPoE message, for transmitting NAS message, i.e., The PPPoE message of PPPoE discovery procedure is fixed network message, carries NAS message in manufacturer's self-defined information therein, such as above-mentioned First NAS message, the second NAS message.For another example, it for the terminal device by IPoE agreement core network access, can use The mode of similar PPPoE, such as during DHCP obtains IP, completing registers kernel network correspondingly can be in DHCP message NAS message is carried in manufacturer's self-defined message.

It should be noted that the parallel registration of 201~step 204 of above-mentioned steps is to fixed network (i.e. access net) and core net Process can be and complete in the different phase based on PPPoE agreement, such as complete in the discovery procedure of PPPoE, or The conversation procedure of PPPoE is completed, and is also possible to complete in the different phase based on IPoE, can also be based on the following new agreement In different phase complete, such as the agreement for being registered to fixed network that definition is new, then the application can be completed eventually based on new agreement End equipment parallel registration to fixed network and core net process.

The application between access device and the CP equipment of core net is communicated by first interface, and first interface is for example It can be N2 interface, NG2 interface etc., and for different terminal devices or for different session identifications, access device is incited somebody to action It is communicated using different first interfaces with CP equipment, therefore further includes establishing user in register flow path shown in the application Fig. 2 (a) Mark and/or session identification, the corresponding relationship with first interface.

For convenience of description, with reference to the accompanying drawing 2 (a), and be illustrated by taking PPPoE as an example, according to different application scenarios, Establishing corresponding relationship will be different.

For example, if also not distributing pppoe session mark before above-mentioned steps 202 for terminal device, then initially setting up use Family mark and the corresponding relationship of first interface, wherein user identifier can one terminal device of unique identification, user identifier for example may be used To be the link information where terminal, the address+virtual LAN media access control (Medium Access Control, MAC) (Virtual Local Area Network, VLAN), device numbering etc., corresponding relationship can exist in table form, Can be in the form of formula, or with chart mode presence etc., the application will be subsequent to illustrate corresponding relationship in table form, For example, the corresponding relationship established is as shown in table 1.

Table 1

User identifier	First interface
		ID1	Interface 2

After establishing corresponding relationship as shown in Table 1, if access device is that terminal device is assigned with pppoe session mark Know, then pppoe session can be identified and be added in above-mentioned table 1, in a kind of possible mode, increased pppoe session mark changes User identifier corresponding first interface, such as shown in table 2.

Table 2

User identifier	Pppoe session mark	First interface
			ID1	Session 1	Interface 3

For example, if the terminal device that the ID1 in table 2 is identified also is corresponding with other sessions, other sessions corresponding first Interface can be different from the corresponding first interface of session 1 of the terminal device, such as shown in table 3.

Table 3

User identifier	Pppoe session mark	First interface
			ID1	Session 1	Interface 3
ID1	Session 2	Interface 2
			ID1	Session 3	Interface 4

In alternatively possible mode, increased pppoe session mark does not change the corresponding first interface of user identifier, then Increase pppoe session mark on the basis of table 1, obtains result as shown in table 4.

Table 4

User identifier	Pppoe session mark	First interface
			ID1	Session 1	Interface 2

Similarly, if the terminal device that the ID1 in table 4 is identified also is corresponding with other sessions, other sessions corresponding One interface is identical as the corresponding first interface of the session of the terminal device 1, as shown in table 5.

Table 5

User identifier	Pppoe session mark	First interface
			ID1	Session 1	Interface 2
ID1	Session 2	Interface 2
			ID1	Session 3	Interface 2

For another example, before above-mentioned steps 202, access device is that terminal device distributes pppoe session mark, then access is set The standby user identifier distribution first interface for being further also based on terminal device, and corresponding relationship is established, establishing corresponding relationship When, it can be identified according to pppoe session and establish corresponding relationship, for example, when the mutual not phase of pppoe session mark of different terminal devices Meanwhile pppoe session mark that is, in a network is uniquely, then can directly to establish pppoe session mark and first interface Corresponding relationship；Certainly, if different terminal devices pppoe session mark may it is identical, can establish user identifier and Pppoe session identifies the corresponding relationship of this two information and first interface.It should be noted that for the first interface used, Either pre-establishing multiple first interfaces, when need to use, corresponding first interface directly is distributed for terminal device, It can be when terminal device is needed using first interface, created first interface by access device and used by terminal device, this Apply for first interface acquisition modes without limitation, either distribution first interface, be also possible to create first interface, It is subsequent no longer to illustrate.

It for example, as shown in table 6, is the corresponding relationship for directly establishing pppoe session mark and first interface.In above-mentioned table 6 Shown in corresponding relationship, each pppoe session mark in a network when it is unique.

Table 6

Pppoe session mark	First interface
		Session 4	Interface 5
Session 5	Interface 6
		Session 6	Interface 8

For example, as shown in table 7, when pppoe session mark is not unique in a network, then can in conjunction with user identifier and Pppoe session mark, establishes the corresponding relationship with first interface.

Table 7

User identifier	Pppoe session mark	First interface
			ID2	Session 1	Interface 4
ID2	Session 2	Interface 3
			ID2	Session 3	Interface 1
ID3	Session 1	Interface 5
			ID3	Session 2	Interface 7
ID3	Session 3	Interface 9

For example, if the same terminal device only corresponds to a first interface, i.e., all PPPoE meetings of the same terminal device The corresponding first interface of words mark is identical, then it is corresponding with first interface can also directly to establish user identifier as shown in table 8 Relationship.

Table 8

User identifier	First interface
		ID2	Interface 4
ID3	Interface 3
		ID4	Interface 1

In short, can establish the corresponding relationship of user identifier and first interface in the process shown in Fig. 2 (a), meanwhile, Pppoe session can also be identified and the corresponding relationship is added, establish pppoe session mark, user identifier, pair with first interface It should be related to, so that access device can be based on the corresponding relationship of foundation, the NAS message from terminal device that will be received, or connect Some pppoe session from terminal device received identifies corresponding NAS message, is sent to core by corresponding first interface The CP equipment of heart net, and, so that access device can be set the CP from core net received based on the corresponding relationship of foundation The message of some standby first interface is sent to corresponding terminal device.

For example, then in above-mentioned steps 202, access device is sent to CP equipment based on the above-mentioned mode for establishing corresponding relationship The process of first NAS message can be：Access device is identified according to the user identifier and/or pppoe session of acquisition, and corresponding Relationship determines first interface, and then access device sends the first NAS message to CP equipment by determining first interface.
