The technical program provides a kind of two layer service processing methods based on long term evolution LTE network, the processing method The Signalling exchange being related between network side and user side.In order to better describe the technical program, (i.e. network on the whole first Side and user side) two layer service processing methods of description, then respectively from user side (using CPE as executing subject) and network side (with NCEP is executing subject) specifically describe embodiment.

As shown in Fig. 1 the signaling of a kind of two layer service processing methods based on long term evolution LTE network of the invention Flow chart.

Referring to FIG. 1, it includes EPC, NCEP, LNS and intranet Intranet that user side, which includes PC and CPE, network side,. Signaling process is as follows:

101, the configurations information of two layer services (i.e. L2 business) is set on LNS.Configurations information includes CPE mark Knowledge, vlan list, LNS gap marker (LNS Tunnel ID) and QoS；Wherein, LNS Tunnel ID can be a LNS's IP address is also possible to the corresponding port numbers of IP address of a LNS.CPE mark is the unique identification of each CPE, for example, moving International mobile subscriber identity (International Mobile Subscriber Identification in dynamic network Number, hereinafter referred to as: IMSI) or international mobile equipment identification number (International Mobile Equipment Identity, hereinafter referred to as IMEI).

102, LNS initiates the registration of two layer services to NCEP.CPE mark, vlan list, tunnel mark are carried in registration information Know, the mode of two layer services of QoS and realization, wherein realizing that the mode of two layer services includes establishing at least two PDN connections (to be based on APN title is established) either establish at least two dedicated bearings；If at least two PDN connections, Tunnel Identifier are established in instruction For APN title, if multiple dedicated bearings are established in instruction, Tunnel Identifier is the packet filter (Packet in this tunnel Filter, hereinafter referred to as PF), when if it is PF, PF is with can be the IP address of at least two LNS or the IP of identical LNS Corresponding at least two port in location.

In the present embodiment, tunnel refers to the tunnel for encapsulating two layer service messages, can be gre tunneling, can also be with It is the tunnel VxLAN.Tunnel is between CPE and LNS.

103, NCEP issues the first configuration information to EPC.Specifically, NCEP to EPC issue the first configuration information be When the registration information for the two layer services registration that the LNS of initialization or network side is initiated to NCEP has update.First configuration Information includes CPE mark, Tunnel Identifier and QoS.Wherein, Tunnel Identifier is APN title described in above-mentioned 1.2 or was grouped Filter PF.

104, CPE registration access LTE network.

105, after CPE registers access LTE network, there is update in the second configuration information of initialization or the CPE When, NCEP issues the second configuration information to CPE, and second configuration information carries vlan list, Tunnel Identifier and vlan list With the corresponding relationship of Tunnel Identifier.

106, at least two carryings are established between CPE and EPC.According to Tunnel Identifier, at least two carryings of foundation can be with It is at least two PDN connections established according at least two APN titles, is also possible to according at least two PF (at least two LNS IP address or identical LNS corresponding at least two port of IP address) establish at least two dedicated bearings.If it is The scheme of PDN connection then usually is initiated to establish by CPE, and if it is the scheme of dedicated bearing, CPE or EPC can be initiated.

In the scheme of PDN connection, the corresponding CPE of each APN is that it distributes an IP address (i.e. IP of CPE by EPC Address), then subsequent established tunnel can be distinguished directly using APN title；In the scheme of dedicated bearing, only one The IP address of CPE, subsequent established tunnel are distinguished by PF, i.e., using the IP address of different LNS or using identical IP address corresponding at least two ports of LNS identify.

The QoS for each carrying established between CPE and EPC is that the first configuration information received according to EPC determines, this The each carrying of sample may be configured to different QoS to meet the transmission demand of two different layer service messages.It needs to illustrate It is that in the technical program, tunnel and carrying are one-to-one relationships, it is also just silent after establishing carrying between CPE and EPC Recognize and establish corresponding tunnel, and the QoS of each carrying is also the QoS in corresponding tunnel.

107, after establishing at least two carryings between CPE and EPC, EPC will send activation notification message to NCEP, will The IP address of the CPE of registration informs NCEP (executing configuration determination/response).

108, after NCEP receives activation notification message, then the IP address of CPE informed that LNS (executes the registration of two layer services Response).

It is connect for CPE with the EPC PDN established in above-mentioned 107 and 108 or dedicated bearing both modes, EPC is sent to The activation notification message and NCEP of NCEP can be variant to the processing of activation notification message, in specific embodiment below in detail Thin description.

Mode A:

109, before CPE transmits two layer service messages, negotiation message is sent to LNS and carries out tunnel negotiation.Wherein, the association CPE mark, the IP address of Tunnel Identifier and CPE are carried in quotient's message.Tunnel Identifier therein can be APN or PF.Root According to different Tunnel Identifiers, the negotiation message that CPE is sent after establishing carrying with EPC is also not quite similar, specific reality below It applies in example and is described in detail.

Mode B:

110, after two layer service messages reach CPE, CPE is packaged into tunnel packet according to the second configuration information and is sent to LNS；

111, LNS receive need to verify after tunnel packet the tunnel packet source address whether the IP for being legal CPE When address, then certification request information is initiated with requests verification to NCEP, the IP address of CPE is carried in certification request information；

112, the NCEP also not no IP address of CPE, then go to EPC again and verified；

113, after EPC is verified, return authentication result to NCEP；

114, authentication result is sent to LNS again by NCEP, is executed tunnel decapsulation by LNS, is finally forwarded to enterprises Network goes to Correspondent Node.

Above-described embodiment describes the signaling process that the lateral network side of user sends uplink tunnel message, correspondingly, working as After two layer service message of downlink reaches LNS, LNS obtains corresponding APN according to the vlan information of the two layer service messages received Or PF.If the tunnel opposite end of the two layer service message of downlink of LNS encapsulation is the PDN connection using the mode of PDN connection When CPE IP address, if using the mode of dedicated bearing, LNS encapsulation two layer service message of downlink tunnel source For the corresponding port of IP address of the corresponding LNS of the PF.
