Embodiment
With preferred embodiment the present invention is described in detail with reference to the accompanying drawings.
Fig. 1 is the flow chart that illustrates according to an embodiment of the method for controlling quantity of network access terminal under routing mode of the present invention.
As shown in Figure 1,, issue maximum access terminals number to gateway, maximum access terminals number is set in gateway by the gateway management system of local side in step 101.Gateway management system and gateway can communicate by TR069.
In step 103, gateway is intercepted and captured the network access request that terminal is sent, and by the phase-split network access request, obtains the hardware address of counterpart terminal, i.e. MAC (medium access control) address.The current access terminals of storage is tabulated in gateway, comprises the hardware address of current access terminals in the tabulation.Gateway relatively in the tabulation of this hardware address and current access terminals the hardware address of storage whether all inequality, if not, then this network access request is sent by access terminals, this network access request of gateway forwards, if, then this hardware address is the hardware address of the terminal of new request online, and gateway obtains current access terminals number by the hardware address number that calculates in the current access terminals tabulation.
In step 105, gateway judges whether current access terminals number is greater than or equal to maximum access terminals number, if then execution in step 107, otherwise, execution in step 109.
In step 107, gateway is refused this network access request, and flow process finishes.
In step 109, gateway allows this network access request, the hardware address that comprises in this network access request is added in the current access terminals tabulation of gateway.
An embodiment according to the method for controlling quantity of network access terminal under routing mode of the present invention, in gateway, set timer for each access terminals, when access terminals is surfed the Net by gateway, the timer of this access terminals of gateway zero clearing, and pick up counting again, can from current access terminals tabulation, not delete when continuing online to guarantee described access terminals, when access terminals is idle for a long time, its corresponding timer is with overtime, this terminal network access request is subsequently refused in this terminal corresponding hardware address of deletion in the current access terminals tabulation in gateway.By such mode, can solve the replacement problem of access terminals.
Fig. 2 is the flow chart that the gateway management system issues maximum access terminals number in illustrating according to one embodiment of the method for the invention to home gateway.
As shown in Figure 2, in step 201, the gateway management system initiates CONNECTIONREQUST to home gateway, and request connects;
In step 203, home gateway is responded the gateway management system request, connects and sets up;
In step 205, home gateway is asked the subsequent operation of gateway management system to gateway management system reporting equipment essential information;
In step 207, gateway management system call SetTerminalNumber method is provided with maximum access terminals number at home gateway;
In step 209, home gateway is responded SetTerminalNumberResponse, and maximum access terminals number issues end;
In step 211, gateway management notifications home gateway issues to be finished, and disconnects connecting.
Fig. 3 is the flow chart that the control online application terminal quantity of the method according to this invention is shown.
As shown in Figure 3,, issue maximum online application terminal number to gateway, maximum online application terminal number is set in gateway by the gateway management system of local side in step 301.
In step 303, gateway obtains the hardware address and the type of terminal in the home network.Concrete realization will described in detail after a while.The type of terminal can be divided into application terminal (as set-top box) and terminal, with the hardware address of terminal and type stores in the terminal attribute tabulation of gateway.
In step 305, gateway is intercepted and captured the network access request that terminal is sent, by the hardware address in the phase-split network access request acquisition network access request.The current access terminals of storage is tabulated in gateway, comprises the hardware address of current online application terminal in the tabulation.Gateway relatively in the tabulation of this hardware address and current access terminals the hardware address of storage whether all inequality, if not, then this network access request is sent by current online application terminal, this network access request of gateway forwards, if, then this hardware address is the hardware address of the terminal of new request online, and tabulation obtains the type of this new terminal according to terminal attribute.Gateway is added up the quantity of the hardware address of online application terminal in the current access terminals tabulation as current online application terminal number.
In step 307, gateway judges whether current online application terminal number is greater than or equal to maximum online application terminal number, if, then refuse this network access request, otherwise, allow this network access request, and in current access terminals tabulation, store the hardware address of this new application terminal.
Under route pattern, the IP address of terminal is distributed by gateway in the home network, and the mode of distribution comprises DHCP and static IP mode.Describe the hardware address of terminal in the gateway acquisition home network and the realization of type in detail at DHCP and static IP mode respectively below.
For the DHCP mode, gateway is enabled Dynamic Host Configuration Protocol server, and terminal one and gateway are set up physical connection, just sends the DHCP request to gateway, and the DHCPDISCOVER packet that gateway sends by analysing terminal obtains the hardware address and the type of terminal." source MAC " field of 6 bytes is the hardware address of terminal in the packet.Comprise the Field type item of marking terminal type in the sub-option60 field of packet afterbody option field, corresponding with it fieldvalue is exactly the type of terminal.The content of Field type item and implication are during fabrication according to the normalized definition of determining, as definition numerical value 1 GC group connector type, the manufacturer of numerical value 2 GC group connectors, numerical value 3 GC group connector models.When family's gateway is received the DHCPDISCOVER packet that user terminal is sent, in analyzing packet during the option60 data segment of DHCP data division, if the numerical value in the Field type territory is 1, then the content in its corresponding field value territory is the type of terminal, as " PC ", " STB " etc.
For using static IP to connect the terminal of gateway, when this terminal and gateway connect, can not send the DHCP request, but send the ARP packet of inquiring about gateway, home gateway is received the ARP packet that a terminal of not carrying out DHCP request is sent, just can confirm that this terminal used static IP, and its terminal type is considered as terminal.
Those skilled in the art will appreciate that by above-mentioned mode the method for controlling quantity of network access terminal under routing mode provided by the invention can be carried out quantity control respectively or separately according to different terminal types to the network access request of terminal.Terminal is distinguished terminal and application terminal,, thereby realize differentiated service, satisfy the business demand of operator the different different terminal quantities of business control.
