To facilitate an understanding of the aspects of the present invention, some techniques used in the aspects of the present invention are explained herein.
And (3) public network mode: the public Mobile Communication System is widely used by common users, and includes GSM (Global System for Mobile Communication), WCDMA (Wideband Code Division Multiple Access) System, and the like.
The private network mode comprises the following steps: the private network design idea adopts a closed mode, namely, the private network is isolated from the public network, even if the private network adopts base station controllers of different manufacturers, for example, communication networks built for meeting the requirements of organization management, safe production, dispatching command and the like in special industries, departments or units such as public security, fire protection and the like, comprise a DMR (Digital Mobile Radio standard) system, a TETRA (Trans European Trunked Radio-pan Trunked Radio) system and the like.
Cluster enhancement mode: the method comprises a private network cluster mode and a public network cluster mode, and the two modes can be switched with each other. If the private network and the public network are communicated at the server side, a public-private network fusion scene is formed, and the unified scheduling function can be realized at the server side regardless of users in the private network or the public network. If the terminal has the access capability of the private network and the public network at the same time, the terminal can select a more appropriate network to reserve so as to provide the optimal service.
Private network clustering: a group communication service is provided over a private network, the group being generally referred to as a Push to talk service (PTT). The private network is a wireless professional network for providing safe and reliable service for a specific industry or group, and a plurality of users generally share a group of channel resources to improve the spectrum efficiency. The private network cluster has a special terminal, a pipeline and a server, can meet the Quality of Service (QoS) of a user to the maximum extent, and provides optimal Service.
And (3) public network clustering: group services are provided over a public network, typically by means of public network operator pipe resources, through client and server communication, the group being commonly referred to as POC (PTT over Cellular). The method has the advantages that the deployment is convenient, and the public network communication service can be realized only by installing the client on the terminal and deploying the cluster service on the server side. With the evolution of public network communication technology, reliable high data service and possibility are provided for 4G technology and the like.
Cell reselection: the terminal measures the signal quality grade of the adjacent cells, evaluates the cells with different priorities according to different reselection rules and reselects one cell. When the terminal performs measurement and cell reselection, the priority information of the adjacent frequency is needed. When the adjacent frequency is not configured with the priority, the terminal will not measure and reselect the frequency point. When the same-frequency cells are reselected, the terminal ignores the priority information of the frequency points, namely, the same-frequency cells are all of the same priority and have no different priorities.
Cell handover is a process in which a terminal reports its location and identity to a network side when the terminal is in an RRC (Radio Resource Control) connected state and in a synchronous state, and the network side allows the terminal to maintain a physical channel and change a serving cell according to various policies.
The network mode is a necessary choice for the terminal to access the network, and at present, the terminal supports three network modes for the user to select, namely a private network mode, a public network mode and a public-private network converged cluster enhancement mode. And (3) public network mode: only the public network is enabled, and the private network is forbidden; the private network mode comprises the following steps: only the private network is enabled, and the public network is disabled; cluster enhancement mode: there are two sub-modes in the mode, and there are two sub-modes in the mode, the cluster enhanced public network mode and the cluster enhanced private network mode. And in the cluster enhancement mode, the terminal automatically selects a private network or a public network between the two sub-modes according to the private network coverage condition of the current place. In the prior art, a terminal can monitor the private network coverage condition in real time in a cluster enhanced private network mode, and can trigger switching to a cluster enhanced public network mode if network loss occurs or the energy value of a service cell is reduced to a certain threshold for a certain time; under the cluster enhanced public network mode, the operation of switching the public network into the private network can be carried out according to the pilot frequency point configuration of the public network operator.
However, due to the fact that the configuration of different frequency points of some public network operators is large, the number of the different frequency points which can be measured by the terminal exceeds the upper limit of the number of the different frequency points, the private network frequency point measurement cannot be started as required, and therefore public network switching cannot be completed. Therefore, the reliability of public network switching and private network switching in the cluster enhancement mode in the prior art is low.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present invention. In a cluster enhancement mode, in order to realize mutual assistance of public and private networks, a terminal needs to switch a data channel wholly under a scene of poor signal quality of the private network, activate a public network mode, access a public network signal and continue to perform cluster services by using a dispatching machine of the public network; when the recovery of the private network signal is detected under the public network signal, the private network signal is switched back to the whole machine, and the private network signal is used for carrying out the trunking service so as to realize the automatic switching of the terminal access mode. In a public-private network convergence scenario, a public network is generally positioned as a supplement of a private network to make up for the shortage of private network coverage. The communication network that the terminal should keep is usually selected by judging the coverage degree of the network signal. If the signal coverage of the private network is poor, the terminal selects to be reserved in the public network; and when the signal coverage of the private network is better, the terminal is kept in the private network. However, when the terminal detects that the private network signal is recovered under the public network signal and the complete machine is required to switch back to the private network signal, if the configuration of the different frequency points of the public network operator is more than the upper limit of the number of the measurable different frequency points of the terminal, the private network frequency point measurement cannot be started as required, so that the public network switching private network cannot be completed, and the reliability of the public network switching private network in the cluster enhancement mode is low.
Referring to fig. 2, which is a flowchart illustrating a method for switching a public network to a private network according to an embodiment of the present invention, an execution main body of the method shown in fig. 2 may be a software and/or hardware device. The subject of execution of the present application may include, but is not limited to, at least one of the following: user equipment, network equipment, etc. The user equipment may include, but is not limited to, a computer, a smart phone, a Personal Digital Assistant (PDA), and the electronic devices mentioned above. The network device may include, but is not limited to, a single network server, a server group of multiple network servers, or a cloud of numerous computers or network servers based on cloud computing, wherein cloud computing is one type of distributed computing, a super virtual computer consisting of a cluster of loosely coupled computers. The present embodiment does not limit this. The method comprises steps S101 to S104, and specifically comprises the following steps:
s101, determining a first to-be-suspended public network frequency point according to a preset public network frequency point measurement list, and suspending measurement of the first to-be-suspended public network frequency point.
Specifically, when the number of the pilot frequency points configured by the operator reaches the upper limit of the measurable pilot frequency points of the terminal, the dedicated network frequency points cannot be added for measurement, and when the dedicated network frequency points cannot be measured, evaluation during switching cannot be completed, so that normal switching to the dedicated network cannot be performed. Therefore, a measurement point needs to be found to measure a private network frequency point, so as to realize evaluation during private network handover, and ensure that a private network can be normally handed over back to the private network in an area covered by the private network.
The preset public network frequency point measurement list comprises a plurality of public network frequency points, and the public network frequency points are all in a real-time measurement state, for example, the energy of the public network frequency points, namely signal values, is measured in real time, so that the mobility of the public network can be evaluated in real time.
The first to-be-suspended public network frequency point is a public network frequency point in a preset public network frequency point measurement list, and after the first to-be-suspended public network frequency point is determined, the first to-be-suspended public network frequency point is subjected to suspension measurement processing, for example, the first to-be-suspended public network frequency point can be removed from the preset public network frequency point measurement list, so that a gap exists in the preset public network frequency point measurement list, and another frequency point can be added for measurement.
The selection method of the first to-be-suspended public network frequency point can be as follows:
acquiring a public network frequency point signal value of each public network frequency point in the preset public network frequency point measurement list; and determining a first to-be-suspended public network frequency point according to the public network frequency point signal value, wherein the public network frequency point signal value of the first to-be-suspended public network frequency point is the lowest.
Specifically, since each public network frequency point in the preset public network frequency point measurement list is always in a state of keeping measurement, the public network frequency point signal value of each public network frequency point can be obtained in real time, and then the public network frequency point signal values of the public network frequency points are compared to determine a lowest public network frequency point signal value to serve as the first to-be-suspended public network frequency point. For example, the preset public network frequency point measurement list includes A, B, C, D, E five public network frequency points, the signal values of A, B, C, D, E five public network frequency points are 46dBm, 50dBm, 47dBm, 48dBm and 49dBm respectively, the lowest signal value is 46dBm, that is, the public network frequency point with the lowest signal value is a, and the public network frequency point a is the first public network frequency point to be suspended.
It should be noted that the determined first to-be-suspended public network frequency point is a public network frequency point of all cells which do not enter the cell reselection or handover target cell.
Before step S101, a preset public network frequency point measurement list of the terminal may also be obtained. Namely, the preset public network frequency point measurement list is a public network frequency point measurement list of the terminal. The terminal may be in an RRC _ IDLE state (radio IDLE state) or an RRC _ CONNECTED state (radio CONNECTED state) in the trunking enhanced public network mode.
And S102, measuring a preset signal value of a private network frequency point at the first to-be-suspended public network frequency point, and acquiring a private network frequency point signal value.
Specifically, in step S101, the first to-be-suspended public network frequency point is already obtained, a preset private network frequency point may be added to the first to-be-suspended public network frequency point, so as to implement measurement of the preset private network frequency point, and obtain a signal value of the private network frequency point.
The signal value of the private network frequency point is used for evaluating the strength of the private network signal, the private network frequency point is measured in real time, the private network can be normally switched back to the private network in an area covered by the private network, otherwise, when the private network signal is weak, the network switching cannot be completed, or the signal is poor after the switching, and the user experience is influenced.
For example, the method for acquiring the signal value of the private network frequency point may be as follows:
adding the preset private network frequency point into the preset public network frequency point measurement list at the first public network frequency point to be suspended; and measuring the signal value of the preset private network frequency point, and acquiring the private network frequency point signal value.
Specifically, because the first to-be-suspended public network frequency point in the preset public network frequency point measurement list is rejected or is suspended for measurement, a special network frequency point can be added to the first to-be-suspended public network frequency point in the preset public network frequency point measurement list for measurement, so as to achieve acquisition of a special network frequency point signal value. For example, when the first to-be-suspended public network frequency point is a, the private network frequency point may be added to a position a in the preset public network frequency point measurement list A, B, C, D, E, that is, the preset public network frequency point measurement list may be updated to the private network frequency point, B, C, D, E, so as to implement measurement of the private network frequency point. It can be understood that when the first to-be-suspended public network frequency point is B, the preset public network frequency point measurement list may be updated to a, the private network frequency point, C, D, E.
For another example, the obtaining the private network frequency point signal value for the preset private network frequency point measurement signal value includes: measuring the signal value of the preset private network frequency point according to the preset times; and acquiring the signal value of the private network frequency point according to the signal value of the preset private network frequency point.
Specifically, the signal value of the preset dedicated network frequency point may be measured according to a preset number of times, for example, the preset number of times may be 3 times, that is, the signal value of the preset dedicated network frequency point is measured 3 times, and then the signal value of the dedicated network frequency point is obtained according to the signal value of 3 times, for example, a weighted average value may be obtained for the signal values of 3 times.
S103, if the signal value of the private network frequency point meets a preset reservation measurement condition, reserving the preset private network frequency point at the first to-be-suspended public network frequency point, and acquiring a reserved private network frequency point.
Specifically, after the signal value of the private network frequency point is obtained in step S102, it may be determined whether the private network frequency point meets a preset reserved measurement condition, so as to determine whether to keep measuring the private network frequency point.
The preset reservation measurement condition may be a preset signal threshold, and after the private network frequency point signal value is obtained, the private network frequency point signal value is compared with the preset signal threshold, for example, when the private network frequency point signal value is greater than the preset signal threshold, it may be determined that the private network frequency point signal value satisfies the preset reservation measurement condition, and when the private network frequency point signal value is less than the preset signal threshold, it may be determined that the private network frequency point signal value does not satisfy the preset reservation measurement condition.
It can be understood that after the private network frequency point signal value satisfies the preset reservation measuring condition, the preset private network frequency point is reserved, namely the private network frequency point is reserved at the first public network frequency point to be suspended, the reserved private network frequency point is acquired, so that the measurement of the private network frequency point is maintained, the private network switching evaluation is convenient to be carried out in real time, and the private network can be normally switched back to the private network in the area covered by the private network.
In some embodiments, if the private network frequency point signal value does not meet a preset reserved measurement condition, deleting the preset private network frequency point in the preset public network frequency point measurement list, and resuming the measurement of the first to-be-suspended public network frequency point. It can be understood that if the signal value of the private network frequency point does not meet the preset reserved measurement condition, that is, the signal value of the private network frequency point is weak, if the public network is switched to the private network, the signal is poor, and the user experience is affected. Therefore, the private network frequency point does not need to be measured, and can be deleted from the preset public network frequency point measurement list. In addition, at this time, the first to-be-suspended public network frequency point is in a suspended state, and in order to not affect the mobility evaluation of the public network, the first to-be-suspended public network frequency point needs to be re-measured, for example, the first to-be-suspended public network frequency point may be re-added to a preset public network frequency point measurement list to ensure the mobility evaluation of the public network.
In other embodiments, if the private network frequency point signal value does not meet a preset reserved measurement condition, deleting the preset private network frequency point in the preset public network frequency point measurement list, and resuming the measurement of the first to-be-suspended public network frequency point further includes: and returning to execute the preset public network frequency point measurement list, determining a first to-be-suspended public network frequency point, and suspending measurement of the first to-be-suspended public network frequency point. It can be understood that after the measurement of the first to-be-suspended public network frequency point is resumed, the measurement of the private network frequency point can be started again to find the private network frequency point with good signal for switching evaluation, so that the private network can be normally switched back in the area covered by the private network.
And S104, switching the public network signal back to the private network signal according to the reserved private network frequency point.
Specifically, after a private network frequency point with a good signal is found, the private network frequency point is kept to be measured for switching evaluation, so that the private network can be normally switched back by using the private network frequency point.
In practical application, the public network signal is switched back to the private network signal to meet at least 2 conditions, one is to keep the measurement of the good private network frequency point of the signal, and the other is to switch in the area covered by the private network, namely, the signal of the private network is switched when being good, so that after the user is switched back to the private network, the signal is good, and the user experience is improved.
In the method for switching a private network in a public network provided in the above embodiment, a first to-be-suspended public network frequency point is determined according to a preset public network frequency point measurement list, and measurement of the first to-be-suspended public network frequency point is suspended; measuring a signal value of a preset private network frequency point at the first to-be-suspended public network frequency point to obtain a private network frequency point signal value; if the signal value of the private network frequency point meets a preset reserved measurement condition, reserving the preset private network frequency point at the first public network frequency point to be suspended, and acquiring a reserved private network frequency point; and switching the public network signal back to the private network signal according to the reserved private network frequency point. And preferentially measuring the public network frequency points to ensure that the mobility of the public network is not influenced, selecting a first public network frequency point to be suspended from the measured public network frequency points, suspending the measurement, and adding a special network frequency point into a measurement list during the period. And if the signal value of the private network frequency point does not meet the preset reserved measurement condition, namely the evaluation criterion, the private network frequency point is removed, and the suspended public network frequency point is added back to the measurement list. Therefore, the invention can ensure that the special network frequency point with good signal can keep measurement for switching evaluation, ensure that the special network can be normally switched back to the special network in the area covered by the special network, and improve the reliability of switching the special network of the public network in the cluster enhancement mode.
In the above embodiment, when the private network frequency point is in the reserved state, the first public network frequency point to be suspended is always in the suspended state, that is, the first public network frequency point to be suspended is in the indefinite suspended state, which may affect the mobility evaluation of the public network.
On the basis of the foregoing embodiment, in order to implement controllable measurement period for suspending a single public network frequency point, refer to fig. 3, which is a schematic flow chart of another method for switching a private network in a public network according to an embodiment of the present invention, including steps S201 to S207, as follows:
s201, determining a first to-be-suspended public network frequency point according to a preset public network frequency point measurement list, and suspending measurement of the first to-be-suspended public network frequency point.
S202, measuring a preset signal value of a private network frequency point at the first to-be-suspended public network frequency point, and acquiring a private network frequency point signal value.
S203, if the signal value of the private network frequency point meets a preset reservation measurement condition, reserving the preset private network frequency point at the first to-be-suspended public network frequency point, and acquiring a reserved private network frequency point.
And S204, switching the public network signal back to the private network signal according to the reserved private network frequency point.
Steps S201 to S204 are similar to steps S101 to S104 in the embodiment shown in fig. 2, and are not described herein again.
S205, determining a second to-be-suspended public network frequency point according to the public network frequency point signal value, wherein the public network frequency point signal value of the second to-be-suspended public network frequency point is the lowest.
The execution order of step S205 and step S204 is not limited.
Specifically, because the signal value of each public network frequency point in the public network frequency point measurement list is in a dynamic change state, one public network frequency point with the lowest signal value can be selected from other public network frequency points, and the public network frequency point is determined as the second to-be-suspended public network frequency point. For example, if the first public network frequency point to be suspended is located at the public frequency point a, the reserved private network frequency point is also located at the public frequency point a. And then, continuously measuring all the signal values of the public network frequency point to find the lowest signal value, and when the signal value of the public network frequency point B is the lowest, determining the position of the public network frequency point B as a second to-be-suspended public network frequency point.
And S206, adding the first to-be-suspended public network frequency point into the preset public network frequency point measurement list at the second to-be-suspended public network frequency point.
Specifically, when the second to-be-suspended public network frequency point is found, the first to-be-suspended public network frequency point may be located at the second to-be-suspended public network frequency point.
And S207, resuming the measurement of the first to-be-suspended public network frequency point, and suspending the measurement of the second to-be-suspended public network frequency point.
Specifically, after the first to-be-suspended public network frequency point is added to the public network frequency point measurement list, measurement of the first to-be-suspended public network frequency point may be started, and measurement of the second to-be-suspended public network frequency point may be suspended.
It can be understood that, because the signal value of each public network frequency point in the public network frequency point measurement list is in a dynamic change state, the position of the second to-be-suspended public network frequency point can also be in a change state, for example, when the signal value of the public network frequency point B is the lowest, the position of the public network frequency point B can be determined as the second to-be-suspended public network frequency point, when the signal value of the public network frequency point C is the lowest, the position of the public network frequency point C can be determined as the second to-be-suspended public network frequency point, thereby realizing frequency point rotation measurement, and wherein the suspended public network frequency point is the frequency point with the lowest signal value, so that the suspension measurement period of the public network frequency point is controllable, the suspension cannot be carried out indefinitely, and the influence on the mobility evaluation of the public network is reduced.
In the embodiment, a frequency point rotation measurement method is adopted, and the suspended public network frequency point is the frequency point with the lowest signal value, so that the suspension measurement period of the public network frequency point is controllable, the suspension is not performed indefinitely, and the influence on the mobility evaluation of the public network is reduced.
