The method provided by the application comprises the following steps:
s110: when the terminal carries out communication service through the first network, whether the signal intensity between the terminal and the current first network base station is smaller than a first preset threshold value or not is judged.
In the current embodiment, when the terminal performs a communication service through the first network, the signal strength between the current terminal and the base station of the first network is continuously monitored to determine whether the signal strength between the terminal and the base station of the first network can complete a high-quality communication service.
Further, in other embodiments, when the terminal performs the communication service through the first network, the signal strength between the terminal and the current first network base station may be detected at intervals of a preset time, and then the detected signal strength between the terminal and the current first network base station is compared with a first preset threshold value, so as to determine whether the signal strength between the terminal and the current first network base station can complete the high-quality communication service.
When the signal intensity between the terminal and the current first network base station is smaller than a first preset threshold value, the signal intensity between the terminal and the current first network base station cannot support the terminal to carry out high-quality communication service; when the signal strength between the terminal and the current first network base station is greater than or equal to a first preset threshold value, the signal strength between the terminal and the current first network base station can support the terminal to perform high-quality communication service.
In the current embodiment, the first network base station to which the terminal is currently connected for performing the communication service is defined as the current first network base station, and the first preset threshold value is an empirical value corresponding to a minimum signal strength value corresponding to the terminal that can complete the high-quality communication service. The high-quality communication service refers to the abnormal phenomena of smooth communication service, uninterrupted voice service and the like, disconnection and the like.
S120: the terminal detects the signal strength of the terminal and the adjacent first network base station based on the at least one adjacent first network base station information fed back by the second network.
When the signal strength between the terminal and the current first network base station is judged to be smaller than a first preset threshold value, the signal strength between the terminal and the current first network base station cannot support the terminal to finish high-quality communication service, and the terminal detects the signal strength between the terminal and other adjacent first network base stations based on at least one piece of adjacent first network base station information fed back by a second network.
Wherein the second network is distinct from the first network, and in the present embodiment, the second network base station is functionally distinct from the first network base station. It is understood that, in other embodiments, the functions of the first network base station and the functions of the second network base station may be integrated into one base station, that is, the integrated base station may support both the first network function and the second network function, that is, the base station may forward communication traffic based on the first network simultaneously, or forward other types of traffic based on the second network simultaneously.
Further, the first network is a narrowband network, the second network is a broadband network, and the communication service is a voice communication service. It is understood that in other embodiments, the first network and the second network may be in other network forms.
The at least one neighboring first network base station information comprises: the current transfer condition and/or the site configuration information of the adjacent first network base station. In the method provided by the present application, the at least one neighboring first network base station information may be obtained by the terminal through the first network and/or the second network before the terminal performs the communication service based on the first network, or may be obtained by the terminal based on the second network during the communication service through the first network, which is not limited herein.
S130: and judging whether the adjacent first network base station is a target base station of the handover or not based on the signal strength detection result and the information of the adjacent first network base station.
Based on the detection result of the signal strength between the terminal and the neighboring first network base station detected in step S120 and the acquired information of the neighboring first network base station, it is determined whether the neighboring first network base station is a target base station for handover.
Since each terminal has a plurality of neighboring first network base stations, when determining the neighboring first network base stations, the determination may be performed based on the sequence of the identifiers of the neighboring first network base stations, or based on the signal strength of the neighboring first network base stations.
The target base station is a base station which can support the terminal to complete high-quality communication service and meet the requirements of a preset base station by the first network signal strength between the target base station and the terminal. The presetting of the base station requirement comprises the step of determining that the communication service of the adjacent first network base station at the relay terminal is relayed according to the relay condition of the adjacent first network base station, and/or the adjacent first network base station has no site limitation.
S140: when the neighboring first network base station is a target base station for handover, the terminal performs handover from the current first network base station to the target base station.
When the adjacent first network base station is a target base station of the handover, the terminal performs a handover operation so that the terminal performs a communication service by handing over to the target base station to provide a high-quality communication service. The handover operation refers to an operation of channel switching that is required to maintain an uninterrupted communication service of the mobile terminal when the terminal moves from an area covered by one base station to an area covered by another base station.
Further, in an embodiment, when the neighboring first network base station is a target base station for handover, the method provided by the present application further includes: the communication traffic is suspended. And suspending the current communication service in progress by the terminal, namely suspending the communication service which is transmitted or received by the terminal under the current first network base station so as to release the channel resource.
Further, in an embodiment, the terminal performing handover from the current first network base station to the target base station includes: when the communication service is in a data sending state at present, the data which is currently sent is stopped to be sent, so that the base station stops transferring the data which is currently sent by the terminal, the channel is released, the terminal is switched to the target base station from the current first network base station in a handover mode, and the communication service is restarted.
In another embodiment, when the communication service is currently in a data reception state, the terminal performing handover from the current first network base station to the target base station includes: and handing over from the current first network base station to the target base station and accessing the communication service so as to provide a high-quality communication service.
Therefore, in the method provided by the present application, different data identifiers are made for the data sending state and the data receiving state, so that the data identifier is further read before the terminal performs handover from the current first network base station to the target base station, so as to obtain the current communication service type of the terminal.
It is to be understood that, in other embodiments, when there is no data identifier to mark the type of the communication service, before the terminal performs the handover from the first network base station to the target base station, it may first determine whether the communication service is in a data receiving state or a data transmitting state, so as to select an accurate handover mode.
In the technical solution provided by the present embodiment, when the terminal performs a communication service through the first network and determines that the signal strength between the terminal and the current first network base station is smaller than the first threshold, the terminal detects the signal strength between the terminal and the neighboring first network base station based on at least one piece of information of the neighboring first network base station fed back by the second network, and then determines whether the neighboring first network base station is a target base station for handover based on a signal strength detection result, and when it is determined that the neighboring first network base station is the target base station for handover, the terminal performs handover from the current first network base station to the target base station. Compared with the prior art, the method and the device have the advantages that the first network for communication service is used for acquiring the adjacent first network information, the second network different from the first network is used for acquiring the adjacent first network base station information, and the adjacent first network base station information can be effectively acquired while the communication service is carried out; and then, judging whether the adjacent first network base station is a cross-zone target base station or not based on the signal strength detection result and the information of the adjacent first network base station, and when the adjacent first network base station is judged to be the cross-zone target base station, executing the operation of switching from the current first network base station to the target base station by the terminal.
Further, in an embodiment, when the communication service is ended, the method provided by the present application further includes:
the terminal sends a stop query message to the adjacent first network base station through the second network so as to inform the adjacent first network base station that the information of the adjacent first network base station is not fed back any more. When the communication service is finished, the second network sends the query stopping message to the adjacent first network base station, so that the situation that the first network base station continues to feed back the information of the adjacent first network base station when the terminal finishes the communication service can be better avoided, and certain resource waste is avoided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a handover method of a terminal according to another embodiment of the present invention. Before or during the terminal performs the communication service through the first network, the method provided by the application further includes:
s201: the terminal sends the inquiry message to the adjacent first network base station through the second network.
Wherein the query message comprises: the base stations may interact with the core network, adjacent to the identification information of the first network base station. In the current embodiment, before or during the communication service of the terminal through the first network, the terminal may simultaneously send the query message to the neighboring first network base station through the second network. Specifically, the terminal sends the query message to the core network through the second network, and then forwards the query message to the neighboring first network base station through the core network.
Further, the terminal sending the query message to the neighboring first network base station through the second network includes: and the terminal sends the query message to the current second network base station, so that the current second network base station forwards the query message to the core network and forwards the query message to the adjacent first network base station through the core network. The inquiry message is sent by the terminal and is transmitted to the adjacent first network base station through the second network, so that the adjacent first network base station reports the current transfer condition and/or the site configuration information of the adjacent first network base station through the core network after receiving the message.
S202: receiving neighboring first network base station information fed back through the second network.
Wherein the neighboring first network base station information comprises: and the current transfer condition and/or site configuration information of the adjacent first network base station. Correspondingly, the information of the adjacent first network base station is sent by the adjacent first network base station and is fed back to the terminal through the core network and the second network, so that the terminal can acquire the current transfer condition and/or the site configuration information of the adjacent first network base station.
When the terminal has a plurality of neighboring first network base stations, in step S201, the plurality of neighboring first network base stations simultaneously send query messages to the plurality of neighboring first network base stations, and after receiving the query messages, feed back the information of the respective corresponding neighboring first network base stations to the terminal, so as to provide information when the subsequent terminal selects a target base station when crossing the area. It is understood that, in other embodiments, when there are multiple neighboring first network base stations, the terminal may further send a query message to the neighboring first network base stations through the second network according to a set rule to obtain the neighboring first network base station information. The set rule comprises sequential sending and one-time simultaneous sending. That is, the terminal may list the required neighboring first network base stations at a time before performing the communication service, and send a query message to the listed neighboring first network base stations; or when the terminal changes the neighboring first network base station, sending an inquiry message to the newly added neighboring first network base station or all neighboring first network base stations, so that the corresponding neighboring first network base stations feed back respective current base station information.
It should be noted that, in the technical solution provided by the present application, the problem that the relay link of the base station of the conventional relay system is unknown before the initiation or access of the communication service and the change condition of the relay link cannot be known in time in the prior art can also be solved. According to the technical scheme provided by the application, the information of the adjacent first network base station can be better acquired before the communication service is initiated or accessed through the adjacent first network base station fed back by the adjacent network base station based on the second network, and the terminal can timely acquire the latest information of the adjacent first network base station when the transfer link changes, so that the terminal can acquire the related information of the transfer link of the base station in advance when the terminal needs to cross the area.
Further, step S202 receives neighboring first network base station information sent through a second network, including: and receiving the information of the adjacent first network base station sent by the current second network base station. And the information of the adjacent first network base station is generated by the adjacent first network base station and forwarded to the current second network base station through the core network.
In other embodiments, when the communication service is ended, the method provided by the present application further includes: the terminal sends a stop query message to the adjacent first network base station through the second network so as to inform the adjacent first network base station that the information of the adjacent first network base station is not fed back any more. The query stopping message is a message sent by the terminal, can be sent to the neighboring first network base station through the first network or the second network, and is used for notifying the neighboring first network base station not to report the information of the first network base station to the terminal.
Further, the terminal sending the stop query message to the neighboring first network base station through the second network includes: and the terminal sends a query stopping message to the current second network base station, so that the current second network base station sends the query stopping message to be forwarded to the core network, and the query stopping message is forwarded to the adjacent first network base station through the core network. In the current embodiment, the terminal can send the query stopping message to the corresponding adjacent first network base station without occupying the resource of the first network base station performing the communication service, so that the occupation of the first network resource is reduced better.
It should be noted that, the core network includes a broadband core network and a narrowband base station control network, when the terminal sends the query message or the query stopping message to the neighboring first network base station through the second network, the terminal first sends the query message or the query stopping message to the broadband core network through the second network, the broadband core network forwards the message to the narrowband base station control network, the narrowband base station control network obtains the target neighboring first network base station of the query message or the query stopping message through analyzing the query message or the query stopping message, and then respectively sends the query message to the target neighboring first network base station obtained through analyzing, so that the corresponding target neighboring first network base station can report the current transfer condition and/or the station configuration information.
Otherwise, when each target neighboring first network base station reports the current transfer condition and/or site configuration information to the terminal, the target neighboring first network base station uploads the current transfer condition and/or site configuration information to the narrowband base station control network, the narrowband base station control network feeds back the current transfer condition and/or site configuration information to the broadband core network, and the current transfer condition and/or site configuration information is fed back to the corresponding terminal based on the second network, so that the terminal can acquire the transfer condition and/or site configuration information fed back by the terminal, and finally the terminal calls a reference when judging whether the current base station is the target base station.
