Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
FIG. 1 is a schematic flow chart of a method according to an embodiment of the present invention. As shown in fig. 1, the method for determining the association relationship between the communication terminal and the station area implemented in this embodiment mainly includes:
In this step, the communication terminal reports the zone information corresponding to the acquisition device to which the communication terminal belongs to the currently accessed communication base station through the access process, so that the communication base station can know whether the communication terminal is the communication terminal in the zone where the communication terminal is located.
Preferably, the communication terminal may report the station information corresponding to the acquisition device to the currently accessed communication base station when the RRC connection is established, and may specifically adopt the following method:
and when the RRC connection is established, the communication terminal carries the station area information corresponding to the acquisition equipment by using the expansion item of the RRC connection establishment completion message, wherein the RRC connection establishment completion message comprises an attachment request.
Preferably, the communication terminal may obtain the station area information corresponding to the acquisition device from the acquisition device to which the communication terminal belongs when the communication terminal is started, and store the station area information.
And 102, the communication base station judges whether the reported station area information is consistent with the station area information of the station area of the communication base station, if so, the access is continuously executed, otherwise, the communication terminal is informed that the access is rejected, and the reject reason is that the communication terminal is not the terminal of the station area of the communication base station.
In this step, the communication base station needs to determine whether the reported station area information is consistent with the station area information of the station area to which the communication base station belongs, and allows the communication terminal to access only if the reported station area information is consistent with the station area information of the station area to which the communication base station belongs, or rejects the access of the communication terminal and notifies the terminal. Therefore, on one hand, the communication base station can determine whether the accessed communication terminal is the communication terminal corresponding to the subordinate power equipment in the station area through interaction with the communication terminal; on the other hand, the communication terminal can know the following conditions based on access: whether the communication terminal is the terminal of the station area to which the currently accessed communication base station belongs is judged, namely, if the communication terminal is successfully accessed, the communication terminal is the terminal of the station area to which the currently accessed communication base station belongs, otherwise, the communication terminal is not the terminal of the station area to which the currently accessed communication base station belongs, and therefore the communication terminal can automatically determine the communication base station needing to be accessed.
Preferably, the communication base station may obtain and store the zone information of the zone from the zone to which the communication base station belongs when the communication base station is started.
Preferably, in this step, when the communication base station determines that the reported cell information is consistent with the cell information of the cell to which the communication base station belongs, the access is continuously performed, which specifically includes the following steps:
the communication base station searches the subscription information of the communication terminal in a local subscription database according to the attachment request;
if the search is successful, the attachment process is completed according to the subscription information;
if the search fails, obtaining the subscription information of the communication terminal from a centralized database, if the obtaining succeeds, storing the obtained subscription information in a local subscription database, and completing the attachment process according to the obtained subscription information; and if the acquisition fails, notifying the communication terminal that the access is rejected, wherein the reject reason is that the communication terminal is not a terminal of a cell to which the communication base station belongs.
In the above method, it is considered that if the terminals are dispersed to each cell area for signing, when the terminals in different cell areas are installed, the terminals need to sign to each cell area respectively, and the cell areas are inconvenient to operate the database, so that for implementation, the operation complexity of the cell areas is reduced, and a centralized signing database is introduced, so that all the terminals sign in one database instead of being dispersed to each cell area for signing. 103, when the communication terminal receives the notification that the access is rejected, adding the communication base station into a search rejection cell set, and selecting other communication base stations except the search rejection cell set for access through cell search until the access is successful;
and when the communication terminal is successfully accessed to the communication base station, setting the communication base station as the communication base station which needs to be accessed after the terminal is restarted.
In this step, when the communication terminal successfully accesses the communication base station, the communication base station needs to be set as the communication base station that needs to be accessed after the terminal is restarted, so that the communication base station is directly selected to be accessed after the terminal is restarted.
In this step, if the communication terminal receives the notification that the access is denied, it is known that the communication terminal is not the terminal of the cell to which the currently accessed communication base station belongs, at this time, the communication base station needs to be added into the search-denied cell set so that the communication base station is not searched during subsequent cell search, cell search is performed again to search for access of other communication base stations, interaction with the communication base station is performed according to step 101 and 103 during each access until a communication base station is successfully accessed, and the cell to which the communication base station belongs is the cell to which the communication terminal belongs, thereby achieving automatic binding between the communication terminal and the communication base station.
According to the technical scheme, the communication terminal can acquire the station area information from the acquisition equipment (concentrator/collector) and interacts with the communication base station to automatically determine the communication base station to be accessed by adopting the embodiment; the communication base station acquires the zone information from the zone, interacts with the communication terminal and determines whether the accessed communication terminal is a communication terminal corresponding to the electric power equipment under the zone where the communication terminal is located; the whole process does not need manual participation to bind the communication terminal and the communication base station, thereby greatly simplifying the equipment installation process and reducing the requirements on installation personnel. The following describes a specific implementation of the above method embodiment with reference to a specific method example. In the example of the method, a set of centralized signing database is deployed and used for conducting unified signing of communication terminal information, and the acquisition equipment is a concentrator. As shown in fig. 2, the method flow includes the following steps:
1. and after the communication base station eNodeB is started, acquiring the cell information from the cell and storing the cell information.
2. And after the communication terminal UE is started, the station area information is obtained from the concentrator and is stored.
3. The communication terminal UE searches the cell, accesses the communication base station eNodeB, and carries the station area information to the communication base station eNodeB in the expansion item of the RRC connection establishment completion message.
4. The communication base station eNodeB judges whether the station area information is consistent with the station area information acquired from the station area
a) If the information of the cell areas is consistent, continuing the attachment process, and the communication base station eNodeB receives the attachment request and searches the subscription information of the terminal in a local subscription database
i. If the contract information can be found, the attaching process is continued
And ii, if the subscription information cannot be searched, sending the terminal information to a centralized database for inquiry. If the centralized database has the subscription information of the UE, the subscription information is fed back to the communication base station eNodeB, and the communication base station eNodeB stores the terminal subscription information and performs authentication and subsequent attachment procedures with the terminal. And if the subscription information of the UE cannot be searched in the centralized database, executing an attachment failure process.
b) And if the station zone information is inconsistent, sending an attachment rejection message to the communication terminal UE, wherein the rejection reason of the message is set to a certain value reserved in LTE (the value indicates that the terminal is not the station zone terminal).
5. If the communication terminal UE receives the attachment rejection message and the rejection reason is 'non-terminal of the station area', the ID number of the physical cell of the station area is written into a rejection access list in a terminal memory. When the communication terminal UE searches for a cell again, it does not search for a station corresponding to the physical cell ID number in the denied access list. And repeating the step 3-4 until the communication base station is accessed.
After the communication terminal is successfully accessed, the accessed communication base stations are recorded, and after the subsequent terminal is restarted, the record is read to directly select the correct communication base station for access.
