In the commercial WiMAX network environment, some operators provide more than 4 frequency points in actual use. In some places, terminals can often scan multiple frequency points that can be accessed, that is, different frequency points overlap. local. In general, in order to ensure that the access success rate is relatively high, the terminal often selects the best frequency of the signal to access. At this time, there may be multiple terminals that select the frequency point to access, and one frequency point can provide The bandwidth is limited. After each terminal is accessed, the available bandwidth will decrease as the number of access terminals increases.

Example 1

As shown in FIG. 4, the embodiment of the passive receiving of the terminal provided by the present invention is described in detail as follows: Step 401: Run the terminal's connection management (CM, Connection Manager) software, and the terminal starts to use the frequency point provided by the operator to initiate the scanning network. , and the available frequency information of the sweep to the signal strength (usually CINR (Carrier to Interference plus Noise Ratio), or RSSI (Received Signal Strength Indication) The reference quantity is added to the frequency point information list, where each frequency point information includes the center frequency, bandwidth, NAPID, BSID, etc., and the frequency of the signal is too low according to the CINR or RSSI value of the frequency point (equivalent to Set a threshold to ensure that the saved frequency is accessible) and filter the frequency of other operators through NAPID. And the results in the current list are continuously refreshed as the terminal periodically scans the network. Then, when the user clicks the link button of the CM software or when the CM software of the terminal is set to be automatically connected, the terminal starts to initiate uplink synchronization and ranging according to the flow of the signal with the strongest frequency in the frequency list according to the flow shown in FIG. After the basic capability negotiation, authentication and registration, the service flow is established with the base station (BS), and the IP address is successfully obtained, and the access is completed (the downlink synchronization occurs in the scanning network phase, and when the connection command is executed, the terminal is already scanning the network. After that, it directly initiates uplink synchronization).

Step 402: After the terminal accesses the terminal, the system sends the available frequency list acquisition request to the terminal to obtain the current available frequency list of the terminal, as shown in S201 in FIG. 2 and S304 in FIG. 3 .

Step 403: After receiving the request from the system side, the first receiving module of the terminal sends the current available frequency point list and the currently accessed frequency point to the system side by using the first sending module, as shown in FIG. 2, FIG. S301 is shown.

The step 402 can be omitted, and the terminal can actively report the current available frequency point list and the currently accessed frequency point to the system side. Step 404: The finishing module on the system side sorts the list of available frequency points received from each terminal, and uses the center frequency of the BSID and the frequency point as an identifier for distinguishing each frequency point, and establishes a database to save each terminal. a list of available frequency points sent;

When the terminal is disconnected, the available frequency list record of the terminal will be deleted automatically. Similarly, if there is a new terminal access, the list of available frequency points reported by the new terminal will be added to the database. At the same time, with the access or disconnection of the terminal, the number of terminals currently connected to each frequency point that the terminal in the database is connecting is counted in real time. As shown in S302 of Fig. 3.

Step 405: After the terminal accesses the terminal, the system searches for the number of terminals currently connected to the frequency point according to the frequency information currently being connected by the terminal, and determines whether the number of terminals that are connected to the frequency point is greater than The number of terminals connected to other available frequency points of the terminal, if yes, step 406; otherwise, the process ends;

Step 406: The system side displays, in the list of available frequency points reported by the terminal, the number of terminals connected to the next frequency point of the current connection frequency point according to the order from strong to weak, if the frequency connection terminal is found If the number of terminals connected to the current terminal access frequency is smaller, the second sending module is started. As shown in S304 of FIG. 3, a message is sent to the terminal to notify the current network environment that there are other idle frequency points. Access, if it is found that the number of terminals connected to the frequency point is greater than or equal to the number of terminal connections of the current terminal access frequency, continue to search for the next frequency point until all the frequency points in the available frequency list provided by the terminal are traversed. . As shown in S303 of Fig. 3.

Step 407: After receiving the message that the idle frequency point is accessible from the system side, the first receiving module of the terminal starts the prompting module to notify the user, waiting for the user to select, as shown in S204 and S205 of FIG. 2 . If the user accepts the recommendation to replace the access frequency, the prompting module will disconnect the current connection, initiate the connection with the idle frequency point from the system side, and restart the initial uplink synchronization, ranging request, basic capability as shown in FIG. After the negotiation, authentication, and registration, the service flow is established with the base station, and after the IP address is successfully obtained, the access is completed.

In another embodiment of the present invention, the terminal may also automatically use the idle frequency to initiate a connection and perform access.

Step 408: After the terminal is disconnected, the sorting module deletes the available frequency point list information reported by the terminal from the database; after the terminal accesses again, the process returns to step 402, and the foregoing process is repeated; If the frequency of the terminal access is already idle, the previous steps will not affect the current connection. Otherwise, the terminal repeats steps 403 and 407, and the system side repeats the processes of steps 402 and 405.

In most commercial environments, the WiMax network supports handover, the terminal will issue a handover scan request, and then the base station will respond. When the condition is met, the terminal will switch to the access frequency point. Therefore, when the user chooses to use the new frequency point. When accessing, the prompting module will suspend the switching function of the terminal to prevent switching to the frequency point of the previous access.

The embodiment of the passive receiving of the terminal provided by the present invention may have multiple access points at the frequency of the terminal, and the number of terminals accessing at the strongest frequency point causes the network speed to decrease, and the new connection In the incoming terminal, the system side gives the terminal user a choice of accessing the relatively idle frequency point, so that the user does not need to try to access other frequency points to maximize the user experience.

Example 2

As shown in FIG. 5, the present invention also provides a detailed description of an embodiment in the case of active inquiry by the terminal:

Step 501: As in Embodiment 1, after scanning the network, the terminal saves the list of available frequency points, and starts to initiate uplink synchronization according to the WiMax access procedure shown in FIG. 1 and uses the most powerful frequency point in the available frequency list. After the Ranging Request, the basic capability negotiation, the authentication and the registration, the service flow is established with the base station (BS), and the IP address is successfully obtained, and the access is completed.

Step 502: Similarly, after the terminal accesses the system, the second sending module sends a request to the terminal to obtain a list of currently available frequency points of the terminal.

Step 503: After receiving the request from the system side, the first receiving module of the terminal sends the current available frequency point list and the currently accessed frequency point to the system side by using the first sending module. As shown in S202 of Figure 2.

Step 504: As in Embodiment 1, the system side establishes an available frequency point list database, and counts the number of terminals connected to each frequency point. When the terminal is connected and the relative idle frequency is already used (that is, the number of terminals connected at the frequency is the least), the system side will not send the idle frequency information to the terminal.

Step 505: As time passes, the frequency of the current terminal connection may appear many end The end is connected, and it is likely to cause network congestion, and the network speed is significantly reduced. At this point, the user can manually select whether to query the frequency status in the current network environment. When the user selects the manual query, the query module on the terminal starts to send the idle frequency query request to the system side, and asks the system side to start searching for the available frequency points in the list of available frequency points reported by the terminal. As shown in 203 of FIG.

Step 506: After the second receiving module of the system receives the idle frequency query request of the terminal, as shown in S305 of FIG. 3, the query module is started to query the other frequency points in the frequency list that can be used by the terminal. According to the order from strong to weak, the number of terminals connected to the next frequency point of the current connection frequency is checked. If the number of terminals connected to the frequency point of the current terminal is found to be less than the terminal access frequency of the current terminal access frequency Number, the second sending module is started, and a message is sent to the terminal to inform that in the current network environment, there are other idle frequency points that can be accessed. If the frequency connection is found to be greater than or equal to the terminal connection frequency of the current terminal access frequency point, The number continues to find the next frequency point until all the frequency points in the list of available frequency points provided by the terminal are traversed. As shown in S302 and S303 of Figure 3.

Step 507: After receiving the query result sent by the system side, the first receiving module of the terminal starts the prompting module according to whether there is an idle frequency point, as shown in S204 of FIG. 2, and informs the user of the query result, as shown in S205 of FIG. 2 It is shown by the user whether to disconnect or use this idle frequency point sent from the system side to initiate a new connection.

In another embodiment of the present invention, the terminal may also automatically initiate an connection using an idle frequency point for access.

Step 508: After the terminal is disconnected, the sorting module deletes the available frequency point list information reported by the terminal from the database.

Step 509: After the terminal accesses again, the terminal performs steps 402 to 408 in Embodiment 1. If the frequency of the terminal access is already an idle frequency, the steps 402 to 408 in Embodiment 1 are not performed. Affects the current connection.

In another embodiment of the present invention, step 509 may not be performed.

In addition, since the WiMax network supports switching, when the user chooses to use the new frequency point to access, the prompting module suspends the switching function of the terminal to prevent switching to the previously accessed frequency point.

An embodiment of the terminal actively querying by the terminal, after the terminal accesses for a period of time, When multiple terminals access a frequency point at the same time, the network speed is gradually reduced. At this time, the user can first query the system side to see if there are any available idle frequency points. If there is, the user can choose to disconnect the current connection. And use new frequency points to connect to improve network congestion.

All the steps of implementing the above two embodiments can complete related operations through program instructions, and the function module on the terminal side can exist as part of the CM software of the terminal, and the system side module can run on a dedicated server provided by the operator or Other servers.

In summary, with the technical solution of the present invention, the user experience in the case of network congestion can be improved.
