Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
In a preferred embodiment of the present invention, based on the above problems in the prior art, a method for maintaining a candidate cell list is provided, which is suitable for a mobile terminal.
In the preferred embodiment of the present invention, as described above, a candidate cell list is maintained in the mobile terminal, where the list includes a plurality of neighboring cells, and according to the previous search and determination, all the neighboring cells included in the candidate cell list have access possibility, that is, can be used as the target of potential cell reselection or cell handover.
In a preferred embodiment of the present invention, as shown in fig. 1, the method for maintaining a candidate cell list specifically includes:
step S1, selecting one neighboring cell which is not checked in the candidate cell list;
step S2, obtaining broadcast information through the broadcast channel of the selected adjacent cell;
step S3, analyzing the broadcast information to obtain system information, and performing a verification operation on the system information:
if the verification operation fails, deleting the adjacent cell from the alternative cell list;
step S4, determine whether there is an unverified neighbor cell in the candidate cell list:
if yes, return to step S1;
if not, exiting.
In a specific embodiment, a candidate cell list including a plurality of neighbor cells associated with a current serving cell is preset in the mobile terminal. The process of accessing the neighbor cell with potential access possibility to the list can be performed in the cell search process of each DRX cycle of the mobile terminal, and the process is not a protection focus of the present invention, and thus is not described again.
In this embodiment, the mobile terminal first selects an unverified neighbor cell from the candidate cell list, and acquires Broadcast information of the neighbor cell through a Broadcast Channel (BCH) of the neighbor cell.
Subsequently, in this embodiment, the mobile terminal parses corresponding system information from the acquired broadcast information, and performs a verification operation on the parsed system information:
1) if the verification operation is successful (i.e. passing the verification operation), it indicates that the neighboring cell is a true cell, that is, the neighboring cell can be retained in the candidate cell list, so that the mobile terminal does not perform any operation with respect to the neighboring cell;
2) if the checking operation fails (i.e. the checking operation is not passed), it indicates that the cell is a false cell, i.e. the neighboring cell needs to be removed from the candidate cell list, so the mobile terminal deletes the neighboring cell from the candidate cell list.
Subsequently, the mobile terminal returns to step S1 described above to continue to perform the verification operation on other neighboring cells that have not been verified in the candidate cell list until all neighboring cells in the candidate cell list have been subjected to the verification operation.
In a preferred embodiment of the present invention, the system information includes a master information block and a system information block, and the system information block includes a system information block 1.
Specifically, in a preferred embodiment of the present invention, the system information obtained by parsing the broadcast information may include:
a Master Information Block (MIB) and a System Information Block (SIB). Further, in the preferred embodiment of the present invention, the system information block includes system information block 1(SIB1) and other system information blocks (for example, SIB2, SIB3, SIB4, etc.). Since the system information blocks other than SIB1 are not relevant to the present solution, they are not described in detail.
In a preferred embodiment of the present invention, as shown in fig. 2, the step S3 specifically includes:
step S31, analyzing the broadcast information to obtain a main information block;
step S32, performing a check operation on the master information block:
if the verification operation fails, deleting the neighboring cell from the candidate cell list, and then turning to step S4;
step S33, according to the main information block, analyzing the broadcast information to obtain a system information block 1;
step S34, performing a verification operation on the system information block 1:
if the checking operation fails, the neighbor cell is deleted from the candidate cell list, and then the process goes to step S4,
if the verification operation is successful, the process goes directly to step S4.
Specifically, in a preferred embodiment of the present invention, the mobile terminal first parses the MIB information from the broadcast information, and performs a checking operation on the parsed MIB information: if the verification is successful, executing the next step; and if the verification fails, directly deleting the adjacent cell from the alternative cell list.
Then the subsequent steps of successful MIB verification are continued: according to the checked MIB information, analyzing the broadcast information to obtain SIB1 information, and checking the SIB1 information: if the verification is successful, the mobile terminal does not perform any operation on the neighboring cell, and then goes to the step S4; and if the verification fails, directly deleting the adjacent cell from the alternative cell list.
In the preferred embodiment of the present invention, since the MIB information includes the content necessary for analyzing the SIB1, the MIB information needs to be analyzed first and verified, and then the SIB1 information is analyzed according to the MIB information and verified on the premise of ensuring the MIB information is correct. Only if both MIB information and SIB1 information pass the check, the neighbor cell is considered to be a true cell and can remain in the candidate cell list. If the MIB information or SIB1 information is not verified, the above-mentioned neighbor cell may be considered as a false cell, and the mobile terminal removes the neighbor cell from the candidate cell list.
In the preferred embodiment of the present invention, when the base station of the neighboring cell broadcasts the system information, a check bit corresponding to the system information is added to the system information;
it is determined whether the check operation on the system information is successful according to the check bit in the above step S3.
In a preferred embodiment of the present invention, the Check operation described above is a Cyclic Redundancy Check (CRC) Check operation. In other words, the check bits described above may be CRC check bits (crcbits).
Therefore, in a preferred embodiment of the present invention, the mobile terminal first selects an unverified neighboring cell in the candidate cell list, and acquires the broadcast information through the broadcast channel of the neighboring cell.
The mobile terminal analyzes the acquired broadcast information to obtain MIB information, and performs CRC check on the MIB information by using a CRC bit:
if the check FAILs (FAIL), the adjacent cell is a false cell, and the mobile terminal directly deletes the adjacent cell from the candidate cell list;
if the check is Passed (PASS), the mobile terminal executes the next operation, that is, according to the MIB information that the CRC check is passed, the SIB1 information is obtained by parsing from the broadcast information, and further CRC check is performed on the SIB1 information by using CRC bit:
if the check FAILs (FAIL), the adjacent cell is a false cell, and the mobile terminal directly deletes the adjacent cell from the candidate cell list;
if the PASS check (PASS) is passed, it indicates that the neighboring cell is a true cell and the mobile terminal does not perform any operation on it.
After the mobile terminal completes the operation of checking one neighboring cell in the candidate cell list, the mobile terminal turns to the next neighboring cell which is not checked and executes the operation until all the neighboring cells in the candidate cell list pass the check.
In the preferred embodiment of the present invention, if a new neighboring cell that has not been verified is added to the candidate cell list during the cell search process, the mobile terminal continues to perform the checksum determination operation on the neighboring cell.
In summary, in the technical solution of the present invention, the mobile terminal performs the following operations on each neighboring cell in the candidate cell list: firstly, acquiring corresponding broadcast information, then analyzing the broadcast information to obtain system information (including the MIB and the SIB1), performing a check operation (for example, CRC check) on the analyzed system information, and finally deleting the neighbor cell with the check failure from the candidate cell list.
