Detailed Description
The following detailed description of embodiments of the invention is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the invention is not limited to the specific embodiments.
The present invention uses the term PDN gateway, which in some documents is referred to as "packet data network gateway", or as PDN-GW, or as PGW, it being understood by a person skilled in the art that the several aforementioned terms refer to the same network entity or network component. The present invention uses the term DNS server, DNS server "domain name server" in some documents, it being understood by those skilled in the art that the several terms referred to above refer to the same network entity or network component.
As described above, there are problems in performing data processing using the existing method. Aiming at the problem that a server connected with a certain PDN gateway can only process and analyze one type of data, according to the existing research on the my, no solution to the problem is proposed in the prior art. At least the prior art CN102088795A (hereinafter, abbreviated as document 1) and CN105164990a (hereinafter, abbreviated as document 2) present a solution to the problem that the server is geographically far from the user equipment. Both of these prior art techniques propose a solution for selecting a gateway (and a server associated with the gateway) for a user equipment that is close to its geographical location, but both of these prior art techniques still have an insurmountable technical problem. For example, in document 1, the mobility management entity MME needs to first decode service request information sent by the UE, then analyze service type information that the UE requests to access, and then select a gateway according to the service type information that the UE requests to access, however, document 1 does not first specify what information the service request information contains, and does not specify what meaning the so-called "service type information that the UE requests to access" has, and the service type information that the UE requests to access is not a well-known and commonly used term in the art, so that a person skilled in the art has a hindrance when using the technical solution of document 1. Furthermore, even if the meaning of "service type information requested to be accessed by UE" can be determined, document 1 requires that MME decodes the "service type information requested to be accessed by UE" and then can determine specific service type information through complicated logic analysis, which consumes a lot of time. Finally, document 1 requires that after the MME analyses a new PGW, the establishment of a bearer between the UE and the PGW is initiated, and a lot of time is consumed when the bearer is established between the UE and the PGW. Therefore, the operation efficiency of the document 1 is low and the document 1 cannot solve the problem that a server connected to a certain PDN gateway can only process and analyze one type of data. In document 2, there is still a problem faced by document 1, for example, an embodiment of document 2 (for example, see paragraphs 60 to 62 of the document 2 specification) requires that the execution subject check a message sent by the UE, for example, document 2 requires that it is judged whether or not a service request of the UE is an "IPv6 neighbor discovery protocol message", which requires at least that the execution subject first decodes the service request of the UE, and then requires that the execution subject first judges whether or not to perform URL check, check of an IP address range, DNS query, or pattern matching on the service request, and after the judgment is made, it is possible to judge whether or not the service request of the UE is an "IPv6 neighbor discovery protocol message", which still takes a lot of time. Meanwhile, document 2 also requires that the user equipment establishes a bearer with the PGW after the execution subject determines a new PGW. Finally, document 2 also fails to solve the problem that a server connected to a certain PDN gateway can only process and analyze one type of data.
Fig. 1 is a schematic diagram of a prior art system architecture, and it should be understood by those skilled in the art that fig. 1 only shows a portion of an existing network system architecture, and that a portion of the entities (e.g., HSS, RCPF, etc.) in the existing network system architecture are omitted. As shown in the figure, in the existing wireless network system, the UE transmits data to the core network through the radio access network, and the core network transmits the data to an external server or internet service through the service gateway and the PDN gateway.
Fig. 2 is a system architecture diagram of a PDN gateway according to an embodiment of the invention. It will be appreciated by those skilled in the art that for clarity purposes, fig. 2 only shows a system architecture relevant to the implementation of the present invention, and that some of the network components belonging to the prior art (e.g., fig. 1) and not relevant to the implementation of the present invention are not shown in fig. 2. As shown, the present invention first transmits data (in the embodiment of the present invention, data to be processed) to the radio access network E-UTRAN by the user equipment UE, then in the core network part, the data is transmitted to the gateway routing function, which then transmits part of the data to, for example, the PDN gateway 1 and transmits the part of the data to the server 1 by the PDN gateway 1, and the gateway routing function transmits another part of the data to, for example, the PDN gateway 2 and transmits the other part of the data to the server 2 by the PDN gateway 2. The gateway routing function may be implemented in software, may be implemented in separate hardware, may be implemented as part of an SGSN, may be a software program within the SGSN, and may be an integrated hardware within the SGSN. Of course, in another embodiment, the gateway routing function may be implemented as part of the MME, the gateway routing function may be a software program within the MME, and the gateway routing function may be an integrated hardware within the MME.
Example 1
FIG. 3 is a method flow diagram of one embodiment of the present invention. As shown in the figure, the data processing method of the present invention comprises the steps of:
step 1: the user equipment sends first data to be processed to the gateway routing function; in a specific example, the first data to be processed may include data to be analyzed and processed by the server, and the first data to be processed may further include application layer instructions (e.g., instructions for the server that may control the server to process the data in a specific manner);
step 2: decoding, by the gateway routing function, a header of the first data to be processed to obtain a first indication indicating a first type of the first data to be processed and partial data having the first type, and a second indication indicating a second type of the first data to be processed and partial data having the second type; in a specific example, the data structure of the first data to be processed may include at least a first indication and a second indication in the header of the first data to be processed, where the first indication may indicate a first type of the first data to be processed (the data in the first data to be processed may cover multiple types, e.g., the first data to be processed may include one or more of text data, audio data, image data, or video data), and in one example, the first indication may use 2-bit data to indicate the first type of the first data to be processed, e.g., bit "00" indicates that the first type of the first data to be processed is text data, bit "01" indicates that the first type of the first data to be processed is audio data, etc.; further, in a specific example, a separation position indicator may be included in the first indication, the separation position indicator indicating a separation position between the partial data having the first type and the partial data having the second type in the payload portion of the first data to be processed, whereby the gateway routing function may determine the type of data included in the payload portion of the first data to be processed according to the first indication, while the partial data having the first type in the payload portion of the first data to be processed may be extracted according to the first indication. The second indication may have the same configuration as the first indication. In the method of the invention, the data type included in the payload part of the first data to be processed is judged, the whole data is not required to be decoded, only the header part of the first data to be processed is required to be decoded, the whole data is not required to be decoded when the part of the data with the first type in the payload part of the first data to be processed is extracted, and only the separator position in the payload is required to be positioned according to the first indication. In addition, the invention has no complex judgment logic for the data type included in the effective load of the first data to be processed, and can greatly improve the operation speed.
Step 3: routing, by the gateway routing function, partial data having a first type to a first PDN gateway based on the first indication and a routing table stored by the gateway routing function, wherein the first PDN gateway has established a bearer with the user equipment; it will be appreciated by those skilled in the art that "the first PDN gateway has established a bearer with the user equipment" means that the UE can send data directly through the gateway (in particular the UE sends data to the base station via the air interface, which then forwards the data to the PDN gateway through the core network) to the external network server without the UE having to first establish a transmission channel with the PDN gateway. This operation prevents the delay in the prior art from establishing a bearer with the gateway after selecting the gateway. In a specific example, the routing table may have the following format:
TABLE 1
| Data type | PDN gateway name | PDN gateway address |
| Text data | First PDN gateway | First IP address |
| Audio data | Second PDN gateway | Second IP address |
| Image data | Third PDN gateway | Third IP Address |
| Video data | Fourth PDN gateway | Fourth IP Address |
After the gateway routing function determines that the payload portion of the first data to be processed includes text data, e.g., according to the first indication, and extracts the text data in the payload portion of the first data to be processed according to the first indication, the gateway routing function may determine that the PDN gateway is named "first PDN gateway", and may then look up the IP address of the corresponding PDN gateway, and then send the text data in the payload portion of the first data to be processed to the first PDN gateway;
step 4: the partial data with the second type is routed by the gateway routing function to a second PDN gateway based on the second indication and a routing table stored by the gateway routing function, wherein the second PDN gateway has established a bearer with the user equipment.
The first type of first data to be processed indicated by the first indication is one of: text data, audio data, image data, or video data;
the second type of the first data to be processed indicated by the second indication is one of: text data, audio data, image data, or video data.
Example 2
In embodiment 2, the first PDN gateway is different from the second PDN gateway, wherein the first PDN gateway is associated with a first server, wherein the second PDN gateway is associated with a second server, wherein the first server is different from the second server. In a specific example, the first server may be, for example, a server that processes exclusively text data, and the second server may be a server that processes exclusively image data, and sending text data to the first server may ensure that there is already a service on the first server for processing text data, thereby avoiding re-instantiating new services on the server; sending the image data to the second server may ensure that a service already exists on the second server for processing the image data, thereby avoiding re-instantiating a new service on the server.
Example 3
In embodiment 3, the data processing method further includes:
after the gateway routing function directly routes the partial data having the first type to the first PDN gateway, starting a first timer by the gateway routing function;
if the gateway routing function receives again other pending data with the first indication in the header before the first timer expires, refreshing the first timer by the gateway routing function; in a specific example, refreshing the first timer includes zeroing the first timer and restarting the timing;
if the gateway routing function does not receive other pending data with the first indication in the header before the expiration of the first timer, sending, by the gateway routing function, a first release indication to the first PDN gateway; in a specific example, before the expiration of the first timer, the gateway routing function not receiving other pending data with the first indication in the header indicates that the UE may no longer transmit data with the first type, and thus the UE no longer needs the service provided by the first server associated with the first PDN gateway, and thus the gateway routing function may trigger the release of the bearer between the PDN gateway and the UE, thereby releasing resources at the PDN gateway;
and after the first PDN gateway receives the first release instruction, the first PDN gateway releases the bearing with the user equipment. In a specific example, the manner in which the PDN gateway releases the bearer with the user equipment is prior art, and during the release of the bearer, the involvement of the MME and other network entities may be required, and a specific procedure may be seen for example in document 1, since this procedure is prior art, the present invention will not be described in detail. After the PDN gateway releases the bearer with the user equipment, the gateway routing function may optionally delete an entry in the routing table for the first PDN gateway.
Further, the data processing method further comprises: after the gateway routing function directly routes the partial data having the second type to the second PDN gateway, starting a second timer by the gateway routing function; refreshing the second timer by the gateway routing function if the gateway routing function receives again other pending data having the second indication in the header before the second timer expires; if the gateway routing function does not receive other pending data with a second indication in the header before the second timer expires, sending a second release indication to the second PDN gateway by the gateway routing function; and after the second PDN gateway receives the second release instruction, the second PDN gateway releases the bearing with the user equipment.
Example 4
In order to prevent the occurrence of data types not described in the routing table in the data to be processed, it is necessary to provide a function of adding a new PDN gateway, which is described in embodiment 4, and in embodiment 4, the data processing method further includes:
the user equipment sends second data to be processed to the gateway routing function; decoding, by the gateway routing function, a header of the second data to be processed to obtain a third indication, wherein the third indication is used to indicate a third type of the second data to be processed and partial data having the third type; judging whether the third indication is stored in a routing table stored by the gateway routing function or not by the gateway routing function; and if the third indication is judged not to be stored in the routing table stored by the gateway routing function, the gateway routing function sends a PDN gateway query message to the DNS server.
Further, the data processing method further comprises:
after the DNS server receives the PDN gateway query message, the DNS server queries a third PDN gateway corresponding to a server with a function of processing partial data with a third type; in a specific example, a specific method for the DNS server to query the configuration data (e.g. IP address) of the PDN gateway can be found in the standards TS 23.234release 11 and TS 23.327release 11 or document 2. In addition, the DNS server needs to record functions supported by a plurality of servers and PDN gateways corresponding to the servers, and this part of information may be written into the memory of the DNS server by the network service provider or the operator by maintaining the DNS server; and transmitting the configuration data of the third PDN gateway to the user equipment by the DNS server.
Establishing a bearer with a third PDN gateway by user equipment; in a specific example, a specific manner of establishing a bearer between the ue and the third PDN gateway is itself a prior art, and in a bearer establishment process, participation of network components such as a base station, an MME, an SGW and the like is required, and in a specific bearer establishment process, reference may also be made to documents 1 and 2, and the present invention is not described in detail.
After the user equipment establishes a bearer with the third PDN gateway, an indication to update the routing table is sent by the user equipment to the gateway routing function.
After receiving the indication to update the routing table, the configuration data of the third type and the third PDN gateway is stored in the routing table by the gateway routing function.
