Problems solved by technology

However, the general filtering gateway cannot implement hierarchical processing of the filtering mechanism based on specific users
The universal filtering gateway adopts personalized information filtering, which is feasible for fixed terminals, but its disadvantage is that it is difficult to meet the roaming scene requirements of mobile terminals
[0012] The Internet filtering solution currently being studied by mobile terminals has high requirements for terminal software and hardware, so its shortcomings are: limited by the bottleneck of terminal processing capabilities, and at the same time, the policy update process of content filtering is complicated and the actual operation is more difficult

Embodiment 1

[0050] image 3 It is a schematic diagram of the structure of the packet data network gateway. As shown in the figure, the PGW may include: a filtering judgment module 301, a forwarding control module 302, and a bearer mapping processing module 303, wherein:

[0051] Filtering judgment module 301, is used for judging whether the user service data packet arriving at PGW satisfies the filtering rule;

[0052] The forwarding control module 302 is configured to discard the user service data packets that do not meet the filtering rules, and forward the user service data packets meeting the filtering rules to the bearer mapping processing module 303 .

[0053] In implementation, after the filtering determination module 301 determines whether the user service data packets arriving at the PGW meet the filtering rules, the forwarding control module 302 discards the user service data packets that do not meet the filtering rules, and forwards the user service data packets meeting the fil...

Embodiment 2

[0071] The information filtering server provided in this embodiment can be used in cooperation with the entities with filtering judgment function mentioned in the previous embodiments, and its role is to provide them with filtering rules based on which the filtering judgment is based.

[0072] Figure 4 It is a schematic diagram of the structure of the information filtering server. As shown in the figure, the server can include:

[0073] Obtaining module 401, configured to obtain filtering rules;

[0074] The sending module 402 is configured to send the obtained filtering rules.

[0075] The user-specific filtering rules formed based on the user's information filtering application can be stored in the information filtering server in this embodiment.

[0076] In a specific implementation, the information filtering server can be a logical entity, which can be directly mapped to the user subscription information field set in the HSS, that is, the content of the information filt...

Embodiment 3

[0088] This embodiment provides an information filtering system composed of the PGW in the first embodiment and the information filtering server in the fourth embodiment.

[0089] Figure 5 It is a schematic structural diagram of the information filtering system, as shown in the figure, the system includes PGW501 and information filtering server 502, wherein:

[0090] The sending module on the information filtering server 502 is connected with the filtering judgment module on the PGW501 through the Ics interface, and is used to send the filtering rules obtained by the acquisition module to the filtering judgment module;

[0091] The filtering determination module on PGW501 is used to determine whether the user service data packets arriving at PGW501 meet the filtering rules sent by the sending module.

[0092] The system can further include:

[0093] HSS503, used to store user subscription information including filtering rules;

[0094] The obtaining module on the information...

Abstract

The invention discloses equipment and a method for filtering information. The method comprises the following steps of: judging whether user service data packets which arrive at the gateway of a packet data network meet a filtering rule or not; discarding the user service data packets which do not meet the filtering rule; and transmitting the user service data packets which meet the filtering rule to a load bearing mapping treatment module. The technical scheme provided by the invention can meet special individuality and meet terminal mobility, and does not have additional software and hardware capacity requirements on a user equipment side.

Description

technical field [0001] The invention relates to the communication field, in particular to an information filtering device and method. Background technique [0002] figure 1 It is a schematic diagram of the roaming access architecture of the EPS (Evolved Packet System, Evolved Packet System) network, figure 2 It is a schematic diagram of the non-roaming access architecture of the EPS network, based on the description of the latest protocol TS23.401-850 of the SAE (System Architecture Evolution, System Architecture Evolution), EPC (Evolved Packet Core, Evolved Packet Core Network) non-roaming and roaming architecture as follows figure 1 and figure 2 shown. Based on the description of the above two schematic diagrams of the EPS system architecture, a brief description of the relevant EPS system process is now given. [0003] 1.
