Definitions
- the present invention relates to the field of communications, and in particular, to a frequency point sorting method and related equipment.
- Wireless communication systems are widely used in various areas of urban and rural areas to provide various communication contents such as voice, video, packet data, messaging, and broadcasting.
- a plurality of cells may be included in a wireless communication system.
- a cell may refer to a minimum coverage area of a node and/or a subsystem of the node serving the coverage area.
- the mobile terminal When the mobile terminal just powers up or just loses the signal covering the cell, it can search for the cell where the current mobile terminal is located, and the cell is called a serving cell.
- the mobile terminal periodically and continuously measures the signal strength of the broadcast control channel (BCCH, Broadcast Common Control Channel) carrier of the serving cell and the neighboring cell, so that when other cell signals are measured to be stronger than the current cell signal, the mobile terminal can timely Switch to the past.
- BCCH Broadcast Common Control Channel
- the mobile terminal generates a candidate list through the system message acquisition of the serving cell, which is called a BCCH allocation table, which is a neighboring cell BCCH frequency list of a cell.
- the BCCH allocation table has frequency points indicated by the network that can be used for cell reselection. These frequency points are used as candidate frequency points of the mobile terminal, and the mobile station periodically measures and synchronizes these frequency points, and receives system messages of the BCCH channel. Used for cell reselection.
- the number of candidate frequencies in the BCCH allocation table is configured according to the network conditions. Some networks have more, some are less.
- the BCCH allocation table is stored in a permanent register or SIM card in the mobile terminal for connection to the operation of the system at power on.
- the interval frequency of the mobile terminal in the standby state and the call state measurement frequency point is different.
- the mobile terminal When the mobile terminal is in the call state, the mobile terminal frequently searches for the frequency of the neighboring cell, so as to switch to the best frequency of the signal in time to maintain the call quality.
- each SIM card uses the universal sorting algorithm to select the best 6 frequency points of the signal in its neighboring cell, and after 5 seconds, press the same algorithm. Reselect the best frequency points of the 6 signals in your neighboring cell for sorting. But many times, when the position of the mobile terminal does not move, the 6 frequencies of the first 5 seconds and the last 5 seconds are exactly the same. Or only some of the frequency changes, there is no need to reorder each time. Moreover, the current mobile terminal gradually appears to be able to read multiple SIM cards. Each SIM card needs to establish a BCCH allocation table, and also needs to search for multiple sets of candidate frequency points, resulting in a sharp calculation of the data of the mobile terminal. If the frequency point sorting method of the prior art is used, the response time of the mobile terminal will be seriously affected, resulting in a decrease in the performance index of the mobile terminal.
- the normal risk data shows that in the actual network, the results of the two sortings are not much different: in the static case (that is, the mobile terminal does not move), in the adjacent two sorting results, only 90% of the cases are 90%. The following frequency changes;
- the mobile terminal when the mobile terminal performs the neighbor cell search, it usually searches for 10 to 20 frequency points, and in the case of the three SIM card mobile terminals, the frequency points can reach 60.
- Embodiments of the present invention provide a frequency point sorting method and related equipment for reducing the amount of operations of frequency point sorting.

- an embodiment of a frequency point ordering method according to an embodiment of the present invention includes:
- the frequency sorting device acquires m frequency points with the strongest signal strength in the neighboring cell as the candidate frequency point, and m is greater than 1.
- the value of m is 6, that is, the six frequency points with the strongest signal strength in the neighboring cell are obtained as the candidate frequency points, and the six frequency points are stored in the BCCH allocation table established by the mobile terminal, so that When the mobile terminal moves, it can find and switch the adjacent cell frequency point with the best signal strength from the candidate frequency points of the BCCH allocation table in time.
- the frequency point sorting device needs to acquire all the n frequency points in the current neighboring cell, because the mobile terminal device needs to update the frequency of the current neighboring cell and the signal strength of the frequency point in time to ensure that the mobile terminal performs the When talking, you can switch to the frequency with the best signal strength for communication.

If the signal intensity of the X-frequency point in the neighboring cell is greater than the weakest frequency point, the X-frequency point is used to replace the weakest frequency point, and the candidate frequency point is searched again.
- the change of the strength of the point signal is small, so in the solution of the present invention, the weakest frequency point is not frequently replaced, and therefore, compared with the prior art, regardless of whether the signal strength of the current frequency point changes, it is always renewed.
- the method of obtaining the strongest frequency points of m signals in n frequency points for sorting, the calculation amount of the frequency point sorting of the present invention is much smaller than the prior art.
- Another embodiment of the frequency point sorting method of the present invention uses a bubbling algorithm as an example to describe the frequency point sorting method of the present invention.
- another embodiment of the frequency point sorting method of the present invention includes:
- the frequency sorting device acquires all k frequency points in the current neighboring cell, and k is greater than or equal to m.
- the number of all frequency points of the current neighboring cell acquired by the frequency sorting device does not change, that is, the values of k and n are generally equal.
- the frequency point sorting device uses the bubble algorithm to sequentially select m frequency points with the strongest signal strength among the k frequency points as the candidate frequency points; specifically:
- the signal strengths of the adjacent two frequency points are compared in turn until the k frequency points are traversed, and the frequency point with the strongest signal strength is output, and the output strongest frequency point is ranked in the BCCH allocation table.
- the frequency point sorting device needs to acquire all the n frequency points in the current neighboring cell, because the mobile terminal device needs to update the frequency of the current neighboring cell and the signal strength of the frequency point in time to ensure that the mobile terminal performs the When talking, you can switch to the frequency with the best signal strength for communication.
- n frequency points After n frequency points are acquired, the frequency points overlapping with the candidate frequency points are marked in the n frequency points, and the repeated frequency points are not compared when traversing.
- the frequency sorting device After the preset duration, acquires the frequency with the weakest signal strength among the m frequency points as the weakest frequency point.
- the specific search method is:
- the signal strengths of the adjacent two frequency points are compared in turn until the m frequency points are traversed, the frequency signal with the weakest signal strength is output, and the frequency point with the weakest signal strength is set. set to The weakest frequency point.
- the preset duration is 5 seconds; when the mobile terminal is in the call state, the preset duration is 0.5 seconds.
- step 206 After obtaining the weakest frequency point, traverse n frequency points in turn, select the frequency points that are not marked among the n frequency points as the X frequency point, and compare the X frequency point with the weakest frequency point, if the X frequency point If the signal strength is greater than the signal strength of the weakest frequency point, step 206 is triggered. If the signal strength of the X frequency point is less than the signal strength of the weakest frequency point, step 207 is triggered.
- the frequency sorting device marks the frequency points that have been selected.
- the X-frequency point is used to replace the weakest frequency point to update the candidate frequency point.
- step 204 is triggered to continue the process of comparing the weakest frequencies.
- the m candidate frequency points are sorted, so that when the mobile terminal moves, the frequency signal with the best signal strength of the current cell can be switched in time, specifically:
- the signal intensity of the adjacent two frequency points is compared in turn until the m frequency points are traversed, and the frequency point with the strongest signal strength is output, and the output strongest frequency point is ranked in the BCCH allocation table.
- the frequency point sorting method in the embodiment of the present invention is described by using a bubbling algorithm, and the prior art uses a bubbling algorithm to discharge the order of the strongest m points of the signal in n frequency points.
- the number of cycles is about mxn-(1+m) xm/2 times. If the scheme of the embodiment of the present invention is adopted, the number of cycles is about mxt+(nm)+mx(m-1)/2 times, where t is the weakest frequency.
- the number of times the point is replaced, the maximum value of t is equal to (nm), mxt is the number of cycles to find the weakest frequency point, and (nm) is the traversal nm
- the number of cycles of the frequency points, mx ( m-1 ) /2 is the number of cycles of the alternate frequency points.
- the normal data shows that after each BCCH allocation table is updated, in the static case (that is, the mobile terminal does not move), in the candidate frequency point, only 90 or less of the frequency points in the 90% of the cases are replaced; in the dynamic case ( That is, the mobile terminal moves.
- the candidate frequency point In the 80% of the candidate frequency points, only 3 or less frequency points are replaced, and the mobile terminal generally searches for 10 to 20 frequency points when performing neighbor cell search.

- the mobile terminal When the mobile terminal is just powered on, the mobile terminal receives the frequency point information of the neighboring cell of the current location provided by the network broadcast, and the frequency information includes 15 frequency points of the neighboring cell, and the mobile terminal measures the 15 frequency.
- the signal strengths of the adjacent two frequency points are compared in turn until the 15 frequency points are traversed, and the frequency point with the strongest signal strength is output;
- the five frequency points with the strongest signal strength among the remaining frequency points are sequentially output.
- the output frequency points are sequentially stored in the corresponding positions of the candidate frequency points of the BCCH allocation table, and are arranged in order of the signal strength from large to small.
- the mobile terminal When the mobile terminal is in the standby state, the mobile terminal updates the BCCH allocation table every 5 seconds; when the mobile terminal is in the call state, the mobile terminal updates the BCCH allocation table every 0.5 seconds. Updating the BCCH allocation table requires reacquiring all the frequency points of the neighboring cells in the current location, and measuring the signal strength of each frequency point. In the prior art, the mobile terminal again uses the method of step one to select the six frequency points with the strongest signal strength among all the frequency points for sorting, but the normal data shows that in the actual network, the BCCH allocation table is updated.
