Specifically, in the embodiment of the present invention, when a User Equipment (UE) accesses a cell to which a vehicle-mounted device belongs, an access request is sent to a base station in the cell, where the access request carries User identification information of the UE, and the User identification information is used to uniquely identify the UE. In one embodiment, the Subscriber identity information may be an International Mobile Subscriber Identity (IMSI). The base station sends the user identification code to the MME, and the MME forwards the user identification code to the HSS.
And the HSS receives the user identification information and acquires user website information corresponding to the user identification information by inquiring a corresponding list of the locally stored user identification information and the user website information. And then, the HSS returns the inquired user website information to the MME, and the MME forwards the user website information to the PGW.
And the PGW receives user website information which is sent by the MME and corresponds to the UE.
Specifically, in the embodiment of the present invention, the PGW establishes a routing message according to the user website information of the UE and the SGI port described in the PGW, where a destination address in the routing message is the user website information, and a next hop address is the SGI port. Then, the PGW forwards the established routing message to other PGWs, so that the other PGWs store the routing message in a local routing forwarding table. Meanwhile, the PGW records the routing message in a local routing forwarding table, so that when receiving the relevant data information, the PGW can send the data information according to the routing message in the routing forwarding table.
In summary, in the technical solution in the embodiment of the present invention, user website information corresponding to a user terminal UE, which is sent by a mobility management entity MME, is received, where the user website information is obtained by a home subscriber server HSS according to user identification information corresponding to the UE by querying a corresponding list of locally stored user identification information and user website information, and is forwarded to the MME; and forwarding the routing message to other PGWs and recording the routing message in a local routing forwarding table, wherein the destination address in the routing message is user website information, and the next hop address in the routing message is an SGI (gateway interface) port to which the PGW belongs. Therefore, the data transmission efficiency and the resource utilization rate are effectively improved, and the user experience is further improved.
Furthermore, in a preferred embodiment of the present invention, the method further comprises:

Referring to fig. 3, a flowchart of a terminal access method according to an embodiment of the present invention is shown, where the method is applied to a home subscriber server HSS, and the method includes:
In order to make those skilled in the art better understand the terminal access method of the present invention, detailed description is given below with specific embodiments.
Fig. 4 is a schematic diagram illustrating a specific flow of a terminal access method in an embodiment of the present invention. In fig. 4:
in the embodiment of the present invention, the process of accessing the vehicle-mounted device 1 by the UE (UE1-UEi) specifically includes:
1) the HSS1 obtains user website information of the UE.
Specifically, in the embodiment of the present invention, the UE1-UEi is included in the user car 1, and in the embodiment of the present invention, the UE may be any device such as a mobile terminal, a PAD, a PC, and the like. During the UE access process, the UE hangs down to CPE1(Customer Premises Equipment) through the switch, so that data interaction between the UE and the access network is performed through CPE 1. Specifically, in the process of accessing the vehicle-mounted device 1, the UE sends an access request to the eNB1(Evolved NodeB, Evolved node b, LTE base station), where the access request carries user identification information of the UE, and in this embodiment, the user identification information is IMSI.
Enb1 forwards the IMSI to MME1, which is sent by MME1 to HSS 1. After receiving the IMSI, the HSS1 obtains the user website information corresponding to the IMSI by querying the locally stored user identification information and user website information correspondence list. In the embodiment of the invention, the user website information comprises the user IP address and the subnet mask. The process of setting the table entries in the list corresponding to the user identifier information and the user website information can be realized by the prior art, and the invention is not repeated.
2) The HSS1 sends the website information to the MME 1.
In an embodiment of the present invention, the HSS1 returns the user website information of the UE to the MME 1. In an embodiment of the present invention, the information returned by the HSS1 to the MME1 records a correspondence between the user website information of the CPE1 and the user website information of the UE. Therefore, when receiving the data sent to the UE, the EPC1 sends the data to the CPE1 according to the user website information of the CPE1, and then the data is sent to the target UE by the CPE 1.
3) The MME1 sends the user website information to the PGW 1.
Specifically, in the embodiment of the present invention, the MME1 sends the user website information to the SGW1(serving gateway), and the SGW1 forwards the website information to the PGW 1.
4) PGW1 stores and forwards routing messages.
Specifically, in the embodiment of the present invention, the communication process between the network elements is signaling plane transmission, that is, signaling messages are interacted. And after receiving the signaling message carrying the user website information sent by the SGW, the PGW performs corresponding processing to extract the user address information. The specific processing procedure is implemented by the prior art, and is not described herein.
The PGW1 establishes a routing message, where a destination address in the routing message is user website information of the UE, and a next hop address is an SGI port of the PGW 1. The PGW1 then records the routing information in the local route forwarding table and triggers the OSPF1 module in PGW 1. After the OSPF1 module is triggered, it learns the routing messages in the routing forwarding table and forwards the routing messages to OSPF modules in other PGWs. The other OSPF module receives a record of the routing message in a local routing forwarding table.
By this point, the UE attach, i.e., access procedure, has been completed. Fig. 5 is a schematic diagram illustrating a flow of service data in the embodiment of the present invention. In fig. 5:
the in-vehicle device 1 includes an eNB1, an EPC1 (in the embodiment of the present invention, the EPC1 includes an MME1, an SGW1, a PGW1), and a server 1. The in-vehicle device 2 includes an eNB2, an EPC2 (in the embodiment of the present invention, the EPC2 includes an MME2, an SGW2, a PGW2), and a server 2.
Specifically, after the UE1-UEi successfully accesses the vehicle-mounted device 1, if the UE needs to acquire data from the public network, the EPC may receive the data through the SGI interface of the PGW1 according to the routing message, transmit the data to the CPE, and then the CPE sends the data to the target UE according to the destination address in the data, that is, the data flow is as shown by the left half line in fig. 5.
In the embodiment of the present invention, if the user car 1 moves under the coverage of the in-vehicle apparatus 2 and accesses the in-vehicle apparatus 2, the UE1-UEi on the user car 1 needs to perform a detach operation with the in-vehicle apparatus 2 in advance. In an embodiment of the present invention, the detach operation may be triggered by: and the MME monitors the state of the UE in real time, and if the UE sends a shutdown or flight mode instruction, the MME triggers a detachment process. In another embodiment of the present invention, the triggering manner of the detach operation may further be: and the MME monitors the state of the UE in real time, if the UE is not in a working state within preset time, the UE can be confirmed to be in an air interface state, and the MME triggers a detachment process. Specifically, the detachment process specifically comprises:
the MME1 sends detach information to the SGW1, where the detach information carries user website information of the UE, and the SGW1 sends route deletion information to the PGW1, where the route deletion information carries the user website information. The PGW1 receives the route deletion information, and deletes the corresponding route message in the local route forwarding table according to the user website information therein. PGW1 then triggers OSPF1 to cause OSPF1 to broadcast the failed routing message to the other PGWs, causing the other PGWs to delete the stored piece of routing message.
The UE may then perform an attach (access) procedure with the vehicle-mounted device 2, and the specific procedure is similar to the steps in the foregoing embodiments and is not described herein again. After the UE and the vehicle-mounted device 2 complete the access process, the local routing forwarding tables of the PGWs in all EPC currently include routing messages whose destination address is UE and next hop address is the SGI interface to which the PGW2 belongs. Therefore, in the case that the UE needs to acquire data, other PGWs will not forward the data, but the EPC2 belonging to the vehicle-mounted device 2 forwards the data according to the local route forwarding list, and the data flow is as shown in the right half line of fig. 5.
In summary, in the technical solution in the embodiment of the present invention, user website information corresponding to a user terminal UE, which is sent by a mobility management entity MME, is received, where the user website information is obtained by a home subscriber server HSS according to user identification information corresponding to the UE by querying a corresponding list of locally stored user identification information and user website information, and is forwarded to the MME; and forwarding the routing message to other PGWs and recording the routing message in a local routing forwarding table, wherein the destination address in the routing message is user website information, and the next hop address in the routing message is an SGI (gateway interface) port to which the PGW belongs. Therefore, the data transmission efficiency and the resource utilization rate are effectively improved, and the user experience is further improved.
