Description
Technical Field

With the popularity of 3G and 4G networks, mobile data services are growing. Outdoor macro stations of 4G and 3G are limited by installation location, building obstruction, network capacity, radio wave propagation loss, and the like, and it is difficult to effectively cover the indoor space. And 4G and 3G indoor distribution systems are limited by factors such as property coordination, power supply, transmission links, installation and the like, so that the installation is difficult or the installation and operation cost is high. The advent of femto cells (also known as femtocells) solved this problem well. The femtocell is small in size, low in transmission power and easy to install, so that the femtocell becomes the first choice for operators to improve indoor coverage quality and enhance user service experience.
The current femto cell usually adopts a dual-mode base station, and the dual-mode base station supports the terminal to work under a 3G network and a 4G network. User perception of Packet Switch (PS for short) service in 4G network is better than that in 3G network. A terminal supporting a 4G network mode under a dual-mode base station usually resides in a 4G cell in an idle state or when performing a PS service, and when performing a Circuit Switched (CS) service, falls back to a 3G cell in a Circuit Switched Fallback (CSFB) manner to perform the CS service, and terminates the CS service and performs Radio Resource Control (RRC) release under the 3G cell, and then returns to the 4G cell in a manner of switching, reselecting, and the like. The terminal supporting the 4G network mode may trigger the establishment of the PS service while establishing the CS service in the 3G cell, where the terminal resides in the 3G cell, and the user of the PS service in the 4G cell perceives better than that in the 3G cell. Therefore, when there is PS service for a terminal from the 4G cell CSFB to the 3G cell, the terminal should be handed over from the 3G cell to the 4G cell as soon as possible to improve user perception.
Based on the above, how to switch to the 4G cell in time when the terminal finishes the PS service in the CS service in the 3G cell is a problem that needs to be solved at present.

Detailed Description
The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
In view of the above problems in the background art, in the prior art, for a terminal that resides in a 3G cell, has 4G capability, and has PS service, the terminal is instructed to switch to the 4G cell in the following two ways:
mode 1: when the terminal residing in the 3G cell finishes the CS service and carries out the PS service, the terminal reports a 3A different system measurement report to the base station, and the base station instructs the terminal to switch to the 4G cell after receiving the measurement report. However, the terminal needs to meet certain conditions for reporting the measurement report, if the reporting conditions are harsh, the measurement report is difficult to trigger, so that the switching is not timely, and the time for reporting the measurement report depends on the network parameter configuration.
Mode 2: when the terminal residing in the 3G cell finishes the CS service and carries out the PS service, the terminal triggers the UserInactive. Triggering the UserInactive means that when the terminal has no flow in uplink and downlink, a monitoring timer is started, and if the uplink and downlink still have no flow after the timer is overtime, the network actively initiates release. The purpose of triggering the UserInactive is to save radio resources, save power for the terminal, and avoid call drop caused by the terminal initiating signaling connection release under the condition of no flow. However, triggering the userinctive has a certain threshold condition, when the threshold condition is too high, the terminal cannot trigger the userinctive in time, and the time for triggering the userinctive depends on network parameter configuration.
It can be seen that the following disadvantages exist when switching in the above two ways: on one hand, when the terminal reports a 3A different system measurement report or triggers the UserInactive, the terminal excessively depends on network parameter configuration. On the other hand, it is difficult for the base station to identify whether the terminal accessing the 3G cell and having the 4G capability is subscribed in the 4G network, and if the base station only has the 4G capability and then switches the terminal to the 4G cell, and actually the terminal is not subscribed in the 4G network, the terminal cannot access in the 4G cell during switching, which causes the terminal to frequently switch between the 3G cell and the 4G cell, thereby affecting the user's perception. Furthermore, some terminals have the capability of working in the 4G network, but do not support the initiation of inter-system measurement on the 4G network, and therefore, the 3A inter-system measurement report cannot be reported, and therefore, the terminal cannot be switched to the 4G network in time. For example, although the Iphone5C has 4G capability, it can only be switched to the 4G cell in an idle cell reselection manner, and when the terminal is switched to the 4G cell in the reselection manner, the terminal frequently reselects among a plurality of 4G cells because specific dominant frequency point information of the switched 4G cell is not clear, so that the terminal is not switched to the 4G cell in time.
In order to solve the above problems in the prior art, an embodiment of the present application provides a terminal switching method. In the technical scheme provided by the embodiment of the application, the multimode base station receives an access request message of a terminal accessing a first mode cell; the multimode base station inquires the identifier of the terminal switched from the second mode cell to the first mode cell and stored by the multimode base station according to the identifier of the terminal; if the identifier of the terminal is inquired, the multi-mode base station determines that the terminal is the terminal switched from the second mode cell to the first mode cell, and indicates the terminal to be switched to the second mode cell after the terminal finishes the circuit switching CS service. It can be seen that, in the embodiment of the present application, the multimode base station determines whether the terminal accessing the first mode cell is switched from the second mode cell, and if so, instructs the terminal to switch to the second mode cell after the terminal finishes the CS service, so that the terminal is switched to the second mode cell in time, thereby avoiding the problem of poor user perception caused by blind redirection when the terminal accessing the first mode cell is not switched from the second mode cell.
Referring to fig. 1, a schematic flow chart of a method provided in the embodiment of the present application is shown. The process comprises the following steps:
step 101: and the multimode base station receives an access request message of the terminal accessing the first mode cell. Step 102: and the multimode base station inquires the identifier of the terminal switched from the second mode cell to the first mode cell, which is stored by the multimode base station, according to the identifier of the terminal. Step 103: if the identifier of the terminal is inquired, the multimode base station determines that the terminal is the terminal switched from the second mode cell to the first mode cell, the terminal is instructed to be switched to the second mode cell after the terminal finishes the CS service, and if the identifier of the terminal is not inquired, the execution operation is consistent with the existing processing flow.
In the embodiment of the present application, the embodiment is described by taking the first mode cell as a 3G cell as an example, and the second mode cell as a 4G cell as an example.
The identifier of the terminal used in the embodiment of the present application is an international mobile Subscriber identity Number (IMSI), and the cell information includes information such as a main frequency point of the cell, and may also include other identifiers and cell information of the terminal, which is not limited in this embodiment of the present application.
In some embodiments, when the terminal is handed over from the 4G cell to the 3G cell, a communication module (hereinafter, referred to as a 4G communication module) in the multimode base station, which implements the 4G communication function, carries the IMSI of the terminal and the primary frequency point information of the 4G cell before the terminal is handed over in an indication message of the handover, and sends the IMSI and the primary frequency point information of the 4G cell to the communication module (hereinafter, referred to as a 3G communication module) in the multimode base station, where the multimode base station stores the IMSI of the terminal and the primary frequency point information of the 4G cell.
And the 3G communication module receives the access request of the terminal, and inquires the IMSI stored in the multimode base station to be switched from the 4G cell to the 3G cell according to the IMSI reported by the terminal accessed to the 3G cell. If the IMSI which is the same as the IMSI of the terminal accessed into the 3G cell is inquired in the IMSI stored by the multimode base station, the terminal accessed into the 3G cell is determined to be the terminal switched from the 4G cell to the 3G cell, and after the terminal finishes the CS service, the multimode base station indicates the terminal to be switched to the corresponding 4G cell according to the stored main frequency point information of the 4G cell corresponding to the terminal.
Referring to fig. 2, a schematic view of a specific processing flow of a 4G communication module provided in this embodiment is provided, where the flow is specifically described by taking a process of a terminal from a 4G cell CSFB to a 3G cell as an example, and the flow specifically includes the following steps:
step 201: and the 4G communication module judges that the terminal needs CSFB to the 3G cell.
In this step, when a terminal that needs CSFB arrives is specifically determined, it is determined whether the terminal residing in the 4G cell of the multimode base station needs to perform a CS service, and if so, the terminal needs to transit CSFB to the 3G cell.
Step 202: the 4G communication module sends the IMSI of the terminal needing CSFB to the 3G cell and the main frequency point of the 4G cell where the terminal CSFB is located to the 3G communication module in CSFB indication information carried by the main frequency point.
Step 203: the 4G communication module indicates a terminal needing CSFB to initiate RRC release, and indicates the terminal CSFB to the corresponding 3G cell according to the main frequency point information of the 3G cell carried in the RRC release message.
In this step, the terminal is pre-configured with the 3G cell of CSFB from the 4G cell CSFB to the 3G cell.
Referring to fig. 3, a specific flowchart of the 3G communication module provided in the embodiment of the present application is shown, where the flowchart specifically includes the following steps:
step 301: the 3G communication module receives the CSFB indication information sent by the 4G communication module and starts a CSFB waiting timer.
In this step, the 3G communication module stores the IMSI carried in the indication information and the main frequency point information of the 4G cell after receiving the indication information, and starts the CSFB waiting timer. The timer is used for controlling the time length of the terminal CSFB, if the terminal CSFB reaches the 3G cell before the timer is overtime, the following process is continuously executed, otherwise, the terminal CSFB is unsuccessful, and the process is ended.
Step 302: and judging whether a terminal which is the same as the IMSI carried in the CSFB indication information exists in the IMSI reported by the terminal accessing the 3G cell before the timer is overtime. If yes, go to step 303, otherwise, go to step 305.
Step 303: the terminal with the same IMSI is considered to be the terminal from the 4G cell CSFB to the 3G cell, and the access is successful in the 3G cell, the timer is stopped, and the step 304 is proceeded.
Step 304: and the 3G communication module indicates the terminal to be switched to the 4G cell after the terminal finishes the CS service.
Specifically, in this step, the terminal initiates RRC release after terminating the CS service, where the RRC release message carries the stored primary frequency point information of the 4G cell, and the terminal switches to the 4G cell according to the primary frequency point information of the 4G cell carried in the release message.
Step 305: and ending the flow.
It can be seen from the foregoing embodiments that, when the multimode base station stores the CSFB indication information carrying the IMSI of the terminal and the main frequency point information of the 4G cell when the terminal goes from the 4G cell CSFB to the 3G cell, the multimode base station determines whether the terminal accessing the 3G cell is from the 4G cell CSFB or not when the terminal accesses the 3G cell. If so, after the terminal finishes the CS service, the multimode base station indicates the terminal to switch to the 4G cell according to the saved main frequency point of the 4G cell, so that the problem that the terminal is frequently switched between the 3G cell and the 4G cell because the terminal cannot be accessed when the terminal of the 3G cell is switched to the 4G cell when the terminal of the 4G cell is not switched from the CSFB of the 4G cell is solved. Further, it can be considered that the 3G cell and the 4G cell under the multimode base station are the same coverage cell, so that the RRC release can be immediately performed after the CS service is finished on the 3G side for the CSFB terminal, and the terminal is switched to the 4G cell according to the main frequency point information of the 4G cell carried in the RRC release message, thereby avoiding the problem that the terminal cannot be switched to the 4G cell in time due to the fact that the threshold conditions for reporting a 3A inter-system measurement report and triggering userinctive are harsh in the prior art, and the 3A inter-system measurement report cannot be reported and the userinctive function cannot be triggered.
