Description

Device and method for analyzing packet data on mobile communication network

technical field

The invention relates to packet data analysis on mobile communication networks. More particularly, the present invention relates to a packet data analyzer and a method thereof, for analyzing packet data and protocols transmitted on an IP (Internet Protocol) network, to provide various statistics, through which analysis is provided to users Provides monitoring information on each service, fully monitors the data network, and generates billing information for each wireless data service.

Background technique

A home mobile communication service method through commercialized digital mobile stations, especially the CDMA (Code Division Multiple Access) type wireless service standard adopts the North American standard IS-95A (Provisional Standard-95A), and IS-95B partially supplements the IS -95A network, and run high-speed data services while maintaining compatibility with existing IS-95A. IS-95A and IS-95B belong to the second generation (2G) in the evolution process of mobile communication networks.

Compared with IS-95A/B, cdma2000-1x, which belongs to the third generation (3G), has improved bandwidth and data rate, and cdma2000-1x is also called IS-95C.

When users who use mobile communication networks, more specifically users who use IS-95A/B and cdma2000-1x networks, wish to receive data services, use PPP (Point-to-Point Protocol) to access the corresponding network to connect to the Internet, and Receive wireless data traffic from a specific server.

Specifically, as shown in Figure 1, when user 10 requests wireless data communication in the 2G IS-95A/B network, user 10 communicates via BTS (base transceiver station) and BSC (base station controller) 20 and PCX (personal Computer switch) 30, PPP access IWF (Interworking Function) 40, and connect to service host 60 through PPP access, so wireless data communication of user 10 can be performed.

When user 10 requests wireless data communication in 3G cdma2000-1x network, user 10 accesses PDSN (packet data serving node) via BTS/BSC 20 and PCF (packet control function) 30, PPP, and from the The service host 60 receives wireless data services.

In the wireless data service system configured as shown in FIG. 1, the successor system after the IWF or PDSN 40 includes an IP network such as Ethernet.

The packet data service analysis in the IP network of above-mentioned configuration relies on IWF, PDSN 40 and the statistics that can be IP equipment also can be the S/H (switching hub) that router provides, but this statistics is useful for analyzing various types of packets Data traffic is not sufficient because the statistics provide the user with limited statistical information for the normal optimum performance of the system.

The respective systems from the BTS/BSC 20 to the S/H and the router 50 only manage these systems themselves, or the connection states of the links connected to them, and the mobile communication network management service provider cannot monitor the service.

As shown in Figure 2, when user 15 requests wireless data in 3G cdma2000-1x, user 15PPP accesses PDSN 35, and accesses AAA (Authentication Authentication Accounting) 45 to user authentication and carries out accounting process, The user 15 is then allowed to receive the desired wireless data service from the service host 65 . In this case, the PCF 25 is connected to the PDSN 35 by using the A11 protocol, and the PDSN 35 is connected to the AAA by using RADIUS (Remote Authentication Dial-in User Service).

Components provided after the PCF 25 in the wireless data service system configured as shown in FIG. 2 include an IP network such as Ethernet. The respective systems including PCF 25, PDSN 35, and AAA 45 only manage the connection status of these systems themselves, or the links connected to these systems, and the mobile communication network management service provider cannot completely monitor the data according to the protocol analysis of the transmitted packet data network.

It is impossible to implement different charges according to the user's use of different services, because in the wireless data service system in Figure 1, according to the time billing method for calculating the data service usage time and the grouping of the total amount of data packets used for calculation billing method to bill the user 10. For example, wireless data services provide data services that handle small text-based payloads, and data services that handle large payloads such as VOD (Video On Demand), but cannot be billed differently according to the different services.

Detailed ways

In the following detailed description, only preferred embodiments of the invention have been shown and described, simply by way of illustration of the best mode believed by the inventors for carrying out the invention. As can be realized, the invention is capable of modifications in various obvious respects, all without departing from the invention. Accordingly, the drawings and description are illustrative in nature and not restrictive.

Fig. 3 shows a system configuration diagram of a mobile communication network using a packet data traffic analyzer according to a first preferred embodiment of the present invention.

As shown in the figure, the system includes BTS/BSC 200, PCX/PCF 300, IWF/PDSN 400, packet data traffic analyzer 500, and S/H and router 600.

The BTS/BSC 200 guarantees the mobility of the user 100, and it is a wireless network that performs handover operations, wireless support and management operations. The BTS is a network terminal connected to the user 100 for processing baseband signals, converting wired and wireless signals, and transmitting and receiving wireless signals, and the BSC is located between the BTS and the PCX/PCF 300 to manage and control the base station.

PCX 300 is a mobile communication exchange that connects user 100 to IWF/PDSN 400 when a user 100 wirelessly accessed through BTS/BSC 200 requests wireless data service, while PCF 300 is a packet controller.

IWF/PDSN 400 is a network linker that connects PCX/PCF 300 to data communication networks including the Internet, where IWF corresponds to the case of 2G IS-95A/B networks, and PDSN corresponds to the case of cdma2000-1x networks .

S/H 600 is a hub connected between IWF/PDSN 400 and service host 700, and is used to send data packets to appropriate ports based on packet addresses, and router 600 connects separate networks using the same transmission protocol.

The packet data service analyzer 500 is connected between the IWF/PDSN 400 and the S/H and the router 600, receives IP packet data transmitted therebetween, analyzes the IP packet data, and provides various statistical data.

FIG. 4 shows a detailed block diagram of the packet data traffic analyzer 500 shown in FIG. 3 .

As shown in the figure, the packet data service analyzer 500 includes an Ethernet splitter 510 , a service analyzer 520 , a statistical storage unit 530 and a statistical query unit 540 .

Ethernet splitter 510 is connected between IWF/PDSN 400 and S/H and router 600, and receives user IP packet data as Tx (transmission) and Rx (reception) data respectively.

Referring to Fig. 5, the Ethernet splitter 510 is connected to the cable connected from the Ethernet Tx port 410 of the IWF/PDSN 400 to the Ethernet Rx port 610 of the S/H and the router 600, and receives data from the user 100 to the service host 700. The uplink packet data is connected to the cable connected from the S/H and the Ethernet Tx port 620 of the router 600 to the Ethernet Rx port 420 of the IWF/PDSN 400 at the same time, and receives the downlink packet to the user 100 from the service server 700 data.

As shown in Figure 6, the Ethernet splitter 510 in the protocol structure of the 2G IS-95A/B network is located at the E-net (Ethernet) as the physical layer of the IWF 400 and the E-net as the physical layer of the service host 700. -net (Ethernet), separates the IP network provided between the IWF 400 and the service host 700 from the physical layer, and receives packet data sent and received between the user 100 and the service host 700.

As shown in Figure 7, the Ethernet splitter 510 in the protocol structure of the 3G cdma2000-1x network is located at the E-net (Ethernet) as the physical layer of the PDSN 400 and the E-net as the physical layer of the service host 700 (Ethernet), separates the IP network provided between the PDSN 400 and the service host 700 from the physical layer, and receives packet data sent and received between the user 100 and the service host 700.

The traffic analyzer 520 receives user IP packet data via the Ethernet splitter 510 as Tx and Rx data, and analyzes them.

Referring to FIG. 8, the traffic analyzer 520 receives the encoded bit stream via the Ethernet splitter 510, and analyzes packet data traffic for each layer of the OSI (Open System Interconnection) model.

For example, since the encoded bit stream includes a plurality of PCIs (Protocol Control Information) and data transmitted between the user 100 and the service host 700, the PCI includes control information for each layer, and the traffic analyzer 520 obtains data from the corresponding encoded Each PCI is removed from the bit stream, and packet data traffic is analyzed in various layers, including data link layer, network layer, transport layer, session layer, presentation layer, and application layer. That is, by removing PCI of the physical layer from the coded bit stream to obtain DLPDU which is a PDU (Protocol Data Unit) of the data link layer, packet data traffic in the data link layer is thus analyzed. By removing the PCI of the data link layer from the DLPDU, the NPDU that is the PDU of the network layer is obtained. By removing the PCI of the network layer from the NPDU, the TPDU that is the PDU of the transport layer is obtained. By removing the PCI of the transport layer from the TPDU PCI, thereby obtaining the SPDU as the PDU of the session layer, by removing the PCI of the session layer from the SPDU, thereby obtaining the PPDU as the PDU of the presentation layer, and obtaining the PDU of the application layer by removing the PCI of the presentation layer from the PPDU APDU, by removing the PCI of the application layer from the APDU, the final transmission data is obtained. Since PCI is included in DPDU, NPDU, TPDU, SPDU, PPDU, and APDU defined separately for each layer, and PCI includes error control information, flow control information, and address information, the traffic analyzer 520 analyzes the data in the user 100 through the respective PDUs. Packet data services of each layer transmitted between the server and the service host 700.

Referring to FIG. 9 and FIG. 10 , the traffic analyzer 520 analyzes traffic through the call progress flow in the 2G and 3G networks to obtain various statistical data.

Figure 9 is the call process flow applied to 2G IS-95A/B.

In step S11, when the user 100 tries to transmit a wireless call to the BTS/BSC 200 in order to perform wireless data communication with the service host 700, in step S12, the BTS/BSC 200 requests a corresponding call setting from the PCX 300.

In step S14, PCX 300 allocates a traffic channel (TCH) to user 100 according to the wireless call setting request provided from user 100, and when the distribution of TCH was completed, PCX 300 requested ISUP (ISDN user part) from IWF 400 to set, In step S16, when the IWF 400 responds to the request for ISUP setting, the ISUP setting between the PCX 300 and the IWF 400 is completed.

When the ISUP setting between the PCX 300 and the IWF 400 is completed, the user 100 requests the PPP data link setting from the IWF 400, and in step S18, when the IWF 400 responds to the above request, the PPP between the user 100 and the IWF 400 Data link is set.

The user 100 requests the distribution of the PPP IP from the IWF 400, and the IWF 400 responds to the request in step S20 and distributes the PPP IP to the user 100.

When the PPP setting between the user 100 and the IWF 400 is completed, in step S22, a TCP connection request and setting operation between the user 100 and the service host 700 is performed via the S/H and the router 600, therefore, in step S24 , the user 100 and the service host 700 send TCP data.

In step S26, when the call is completed during the TCP data transmission, the TCP connection is disconnected.

As for the 2G call process flow, the service analyzer 520 is provided between the IWF 400 and the S/H and the router 600, and performs TCP setting, receives the TCP data transmission service, and analyzes the TCP data transmission service represented by the dotted line ring A in Fig. 9 , so as to find the successful access rate, access time, access failure factors, data usage statistics and menu click statistics for the service host 700.

Similar to this, Figure 3 shows the call process flow applied to the 3G cdma2000-1x network.

In step S30, when the user 100 tries to call transmission in order to carry out wireless data communication with the service host 700, to set up the wireless call to BSC/PCF 200 and 300, when the corresponding wireless call is established, the user 100 requests the RP from PDSN 400 Registration, in step S32, when PDSN 400 replies to this request, the RP registration between user 100 and PDSN 400 is completed.

When the RP registration between the user 100 and the PDSN 400 is completed, the user 100 requests the PPP data link setting from the PDSN 400, and in step S34, when the PDSN 400 replies to the request, the PPP data is established between the user 100 and the PDSN 400 Link. The user 100 requests the allocation of PPP IP from the PDSN 400, and in step S36, the PDSN 400 allocates the PPP IP to the user 100 in response to the request.

In step 38, when the PPP setting between the user 100 and the PDSN 400 is completed, the TCP connection request and the setting operation between the user 100 and the service host 700 are performed via S/H and router 600, and in step S40, the user 100 and service host 700 send TCP data. In step S42, when someone has hung up the phone during the TCP data transmission, the TCP connection is canceled.

In the 3G call process flow, the traffic analyzer 520 is provided between the PDSN 400 and the S/H and the router 600, executes the TCP setting, receives the TCP data transmission service depicted by the dotted line ring B in Figure 10, and analyzes the TCP data The service is transmitted, and the successful access rate, access time, access failure factors, data usage statistics and menu click statistics are searched for the service host 700.

The traffic analyzer 520 analyzes traffic through the following various data as described above.

1) OSI layer 7 Tx/Rx data usage statistics (physical layer or application layer)

2) Tx/Rx data usage statistics obtained by applying subnet mask to source IP/destination IP

3) Tx/Rx data usage statistics for each device using IWF/PDSN IP address pool

4) A11 access/PDSN PPP access statistics for each base station classified by service option

5) Application statistics using TCP/UDP port numbers

The statistics storage unit 530 stores the result data analyzed by the traffic analyzer 520 on the packet data received via the Ethernet splitter 510, and includes a database for storing various data including analysis data, and a database for retrieving data based on external data. A database manager that requests the retrieval of appropriate data from a database and provides the results of the retrieval.

The statistical query unit 540 includes a GUI (Graphical User Interface) as a user interface, and retrieves various data stored in the statistical storage unit 530 to provide statistical information required by the user.

Through the GUI of the statistical query unit 540, the user obtains various real-time statistical data obtained by analyzing direct services on the IP network. The real-time statistical data includes the following statistics, the total communication amount of Rx, Tx and Rx+Tx data, the access probes of each layer, the number of successes, the number of failures and the current status, and further includes the usage statistics of each IP for each application, each The statistics of the successful access rate of the service, the statistics of the response times, and the statistics of the success rate of the PPP session of each base station.

As described above, by using the Ethernet splitter 510 to separately analyze the traffic on the physical layer in the IP network, compared with the data traffic statistics provided by the conventional IWF and PDSN, a large amount of statistical information is obtained, thereby more effectively It becomes possible to manage IP networks.
