Background
At present, in order to meet the increasing travel demands of users, more and more traffic lines (such as high-speed rail tracks, train tracks, expressways and the like) are built in China. Because some traffic routes are remote, when a user drives on the traffic routes, signals cannot be received by the electronic equipment or the signals are not good.
For example, a long Term Evolution (L ong Term Evolution, L TE) system is covered along a high-speed rail, and the L TE system can meet business requirements of users for surfing the internet, making calls and the like when riding high-speed rails.
However, in the case where the electronic device resides in a serving cell of one communication system dedicated to the transportation line, the electronic device frequently reselects to another communication system. The electronic device may then reselect back to the original communication system from the other communication system. This results in frequent ping-pong reselection of the electronic device between the two communication systems, which affects the normal use of the electronic device by the user.

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 some, not all, embodiments of the present invention. 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.
For example, a long term Evolution (L ongTerm Evolution, L TE) network is covered along the high-speed rail, and the L TE network can meet the business requirements of users for surfing the internet, making calls and the like when the users sit on high-speed rails.
For example, in the case of an electronic device residing in an L TE network, the electronic device can easily reselect to a Global System for mobile communication (GSM) network due to the high reselection threshold of the heterogeneous System.
In view of the above technical problems, an embodiment of the present invention provides a cell reselection method. Fig. 1 shows a flowchart of a cell reselection method according to an embodiment of the present invention. The cell reselection method is applied to an electronic device, and as shown in fig. 1, the cell reselection method includes:
s101, under the condition that the electronic equipment resides in a first service cell, acquiring a reselection parameter value of the first service cell; wherein the first serving cell is a serving cell of a first communication system associated with the transportation line.
S102, determining whether the electronic equipment meets the inter-system reselection rule according to the reselection parameter value of the first service cell. And executing S103 if the electronic equipment is determined to meet the preset inter-system reselection rule, and executing the original process if the electronic equipment is determined not to meet the inter-system reselection rule.
Wherein the reselection parameter value of the first serving cell comprises: a serving cell ranking result (serving cell Srxlev) of the first serving cell and a low priority radio access technology signal reception level (lower priority RATSrxlev).
For example, the first communication system is an L TE system, and the inter-system reselection rule includes the following two conditions:
serving cell Srxlev<ThreshServing,LowP；
lower priority RAT Srxlev>ThreshX,LowP；
wherein ThreshServing, &lttttranslation = L "&tttl &ltt/t &gtt owP is the L TE system message 3 service reselection parameter, ThreshX, &lttttranslation = L" &tttl &ltt/t &gtt owP is the inter-system reselection parameter of the system message 3 of the L TE system.
serving cell Srxlev is RSRP-Qrxlemin, where RSRP is reference signal reception Quality (referential signal Receiving Quality), and Qrxlemin is a serving cell access threshold parameter of system message 1 of the L TE system.
S103, determining whether a first parameter value representing the signal intensity of the first serving cell meets a first preset condition; in case it is determined that the first parameter value related to the signal strength of the first serving cell satisfies the first predetermined condition, performing S104; in case it is determined that the first parameter value related to the signal strength of the first serving cell does not satisfy the first predetermined condition, S105 is performed.
The first parameter value may include a Reference Signal Received Power (RSRP). The first parameter value satisfying the first predetermined condition includes the RSRP being greater than a predetermined power threshold. As one example, the predetermined power threshold ranges from-115 dBm to-110 dBm. For example, the predetermined power threshold is-114 dBm.
The first parameter value may include a signal lattice number, and the first parameter value satisfying the first predetermined condition includes the signal lattice number being greater than or equal to a predetermined lattice number. For example, the first parameter value satisfying the first predetermined condition includes a number of signal lattices being greater than or equal to 3.
Wherein the determination of whether the first parameter value satisfies the first predetermined condition is to determine whether the inter-system reselection by the electronic device is reasonable. Under the condition that the electronic equipment meets the inter-system reselection rule, if the first parameter value meets a first preset condition, the signal of the first service cell is strong, and the first service cell can meet the service requirements of the electronic equipment, such as making a call or surfing the internet. In this case, it is not reasonable to perform inter-system reselection, i.e., the electronic device does not need to perform inter-system cell reselection, so S104 is performed.
S104, controlling the electronic equipment to stay resident in the first service cell. I.e. the electronic device does not perform inter-system cell reselection.
And S105, controlling the electronic equipment to reselect the inter-system cell under the condition that the first parameter value does not meet the first preset condition.
As an example, the controlling the electronic device to perform the inter-system cell reselection in S105 includes: and reselecting a second service cell of the second communication system, and controlling the electronic equipment to be switched to the second service cell.
Wherein the priority of the second communication system may be lower than the priority of the first communication system. Therefore, the inter-system reselection of the embodiment of the present invention is to perform reselection of a communication system with a low priority.
The first communication system is L TE system, and the second communication system is GSM system or Wideband Code Division Multiple Access (WCDMA) system.
Or, the first communication system is a New Radio (NR) independent networking (SA), and the second communication system is an L TE system, a WCDMA system, or a GSM system.
In the embodiment of the present invention, in a case where the electronic device resides in a first serving cell of a first communication system associated with a transportation line, although the electronic device satisfies a inter-system reselection rule, it is further required to determine whether a first parameter value characterizing signal strength of the first serving cell satisfies a first predetermined condition, and control the electronic device to perform inter-system reselection in a case where the first predetermined condition is not satisfied. Therefore, the embodiment of the invention improves the threshold of the electronic equipment for performing the inter-system reselection, so that the electronic equipment can not perform the inter-system reselection easily, thereby preventing the electronic equipment from frequently performing ping-pong reselection between two communication systems and avoiding influencing the normal use of the electronic equipment by a user.
In addition, it is found through analysis that it may happen that the user is not traveling on the traffic route, but the electronic device of the user resides in a serving cell of the first communication system associated with the traffic route. For example, a user is near a high-speed rail but not riding on a high-speed rail. In this case, the user is not traveling on the traffic line, and it is not necessary to make the reselection threshold of the communication system high. Therefore, the embodiment of the invention can be applied to the electronic equipment of the user driving on the traffic route.
Based on the above analysis, in order to adapt the embodiment of the present invention to the electronic device of the user traveling on the traffic route, in one or more embodiments of the present invention, before S102, the cell reselection method further includes:
acquiring geographical position information of the electronic equipment in a preset time period;
determining the movement information of the electronic equipment according to the geographical position information;
it is determined whether the movement information satisfies a second predetermined condition.
S102 includes: and determining whether the electronic equipment meets a preset inter-system reselection rule or not under the condition that the mobile information meets a second preset condition.
In the embodiment of the invention, the movement information of the electronic equipment is determined according to the geographical position information of the electronic equipment in the preset time period, and whether the movement information meets the second preset condition is determined, so that whether the user of the electronic equipment drives on the traffic route is determined. And determining whether the electronic equipment meets the inter-system reselection rule or not under the condition that the movement information meets a second preset condition, namely under the condition that the user of the electronic equipment runs on a traffic line. Therefore, the embodiment of the invention is suitable for the electronic equipment of the user driving on the traffic route.
The following describes determining whether the movement information satisfies the second predetermined condition.
In one or more embodiments of the invention, the movement information includes a location change trajectory.
Determining whether the movement information satisfies a second predetermined condition, including:
acquiring at least one traffic line related to the geographical position information according to the geographical position information;
it is determined whether a link matching the location change trajectory exists in the at least one link.
In the embodiment of the invention, according to the geographical position information of the electronic device within a predetermined time period (for example, 20 minutes), the position change track of the electronic device within the predetermined time period can be determined. According to the geographical position information of the electronic equipment (such as the latest acquired geographical position information), at least one traffic line near the position of the electronic equipment is acquired, and whether a traffic line matched with the position change track of the electronic equipment exists in the traffic lines is determined. If the traffic route exists, the user is indicated to travel on the traffic route. Therefore, the embodiment of the invention is suitable for the electronic equipment of the user driving on the traffic route.
In one or more embodiments of the invention, the movement information includes a movement speed.
Determining whether the movement information satisfies a second predetermined condition, including:
it is determined whether the speed of movement is greater than a predetermined speed threshold.
If the user drives on the traffic route, the moving speed of the electronic device is relatively high. Therefore, in the embodiment of the invention, whether the moving speed of the electronic equipment is greater than the preset speed threshold value or not is determined, and if the moving speed of the electronic equipment is greater than the preset speed threshold value, the user is indicated to travel on the traffic route. Therefore, the embodiment of the invention is suitable for the electronic equipment of the user driving on the traffic route.
In order to determine whether the first serving cell can provide a signal with better quality for the electronic device, another cell reselection method is provided in an embodiment of the present invention. Fig. 2 is a flowchart illustrating another cell reselection method according to an embodiment of the present invention. The cell reselection method is applied to an electronic device, and as shown in fig. 2, the cell reselection method includes:

In case it is determined that the electronic device satisfies the inter-system reselection rule, S203 is performed. And executing the original flow under the condition that the electronic equipment is determined not to meet the inter-system reselection rule.

The second parameter value satisfying the third predetermined condition includes: the RSRQ is greater than a predetermined quality threshold (e.g., a predetermined quality threshold of-12 dB or-15 dB), and/or the signal-to-noise ratio is greater than a predetermined signal-to-noise ratio threshold. For example, the second parameter value satisfying the third predetermined condition may include an RSRQ greater than-12 dB and/or a signal-to-noise ratio greater than 5 dB.
