Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
As shown in fig. 1, a flowchart of steps of a talk right switching method applied to a dual mode terminal in an embodiment of the present invention is shown, where the dual mode terminal includes a narrowband mode (e.g., PDT mode) and a wideband mode (i.e., B-Trunc mode), and the method includes the following steps:
step 101: when the dual-mode terminal detects that the reliability of the group calling voice uploaded through the narrow-band mode is lower than a preset threshold value, an uplink call right switching request message requesting to switch the uplink call right from the narrow-band mode to the wide-band mode is sent to the network side.
In this step, specifically, the dual-mode terminal may predict the reliability when uploading the group call voice through the narrowband mode according to a signal to interference plus noise ratio (SINR) and a Reference Signal Received Power (RSRP), for example, when it is detected that the SINR is greater than a preset SINR threshold and the RSRP is less than a preset RSRP threshold, it may be determined that the reliability when uploading the group call voice through the narrowband mode is lower than the preset threshold.
In addition, specifically, when it is detected that the reliability of the group call voice uploaded through the narrowband mode is lower than the preset threshold, an uplink talk right switching request message requesting to switch the uplink talk right from the narrowband mode to the broadband mode may be sent to the network side, so that the network side may allow the uplink talk right to be switched.
Step 102: and receiving a speaking right switching instruction which allows the upstream speaking right to be switched from the narrowband die to the broadband die according to an instruction sent by the upstream speaking right switching request message and switching the upstream speaking right from the narrowband die to the broadband die according to the speaking right switching instruction.
In this step, specifically, after receiving the uplink speaking right switching request message, the network side may detect whether the broadband mode satisfies the uplink speaking right switching condition, and at this time, if the network side detects that the broadband mode satisfies the uplink speaking right switching condition, send a speaking right switching instruction indicating that the uplink speaking right is allowed to be switched from the narrowband die to the broadband die to the dual-mode terminal according to the uplink speaking right switching request message. At this time, the dual-mode terminal receives the speaking right switching instruction and switches the uplink speaking right from the narrow-band die to the wide-band die according to the speaking right switching instruction.
Specifically, whether the broadband mode meets the uplink talk right switching condition or not may be detected, that is, whether the broadband mode performs talk right queuing in the broadband module is detected, and if it is detected that the broadband mode performs talk right queuing in the broadband module, it is determined that the broadband mode meets the uplink talk right switching condition.
Thus, when detecting that the reliability of the group calling voice uploaded through the narrow-band mode is lower than the preset threshold value, the dual-mode terminal in this embodiment sends an uplink talk right switching request message requesting to switch the uplink talk right from the narrow-band mode to the wide-band mode to the network side, and receives a talk right switching instruction sent by the network side, so that the uplink talk right is switched from the narrow-band mode to the wide-band mode, thereby realizing talk right switching between the narrow-band mode and the wide-band mode in the dual-mode terminal, ensuring that the uplink group calling can be continuously performed through the wide-band mode when the narrow-band mode of the dual-mode terminal cannot normally upload the group calling voice, and ensuring that the uplink group calling process is smoothly performed.
Further, the uplink speaking right switching request message can be a P _ MAINT message, and a reserved value of a cell in the P _ MAINT message is defined as a request for switching the uplink speaking right from a narrowband die to a wideband die; the talk burst switch command is a P _ PROTECT message, and the PK in the P _ PROTECT message is defined to indicate that the uplink talk burst switch is allowed.
For example, cell mk in the P _ MAINT message may be 1112, and this value is defined to indicate that the upstream floor is requested to be switched from narrowband to wideband; in addition, PK in the P _ PROTECT message allows conversion, i.e. indicates that the dual-mode terminal is allowed to perform uplink right conversion.
Therefore, by defining the cell in the P _ MAINT message, determining the defined P _ MAINT message as the uplink talk right switching request message, and by performing the permission switching definition on PK in the P _ PROTECT message, and determining the defined P _ PROTECT message as the talk right switching instruction, the application of the dual-mode terminal to talk right switching and the response of the signaling message can be realized under the condition of not changing the conventional signaling mechanism and protocol of PDT, the smooth switching of the uplink group call of the dual-mode terminal from a narrowband mode to a broadband mode is ensured, and meanwhile, the group of downlink group call voice service is continuously received without influencing the members at the narrowband side of a mixed group.
In addition, further, when receiving a talk right switching instruction which allows the uplink talk right to be switched from the narrowband die to the broadband die according to the instruction sent by the uplink talk right switching request message, the dual-mode terminal may receive the talk right switching instruction broadcast in the TS coverage area where the network side group call voice is located.
Specifically, after detecting that the broadband mode satisfies the uplink talk right switching condition, the network side may broadcast the talk right switching signaling in a coverage area of a cluster base station (TS for short) where the group call voice is located. Therefore, the broadcast mode does not change the original P _ PROTECT message sending mechanism of PDT, the same group of called parties can also receive the message and can judge the message through the PK value, and the downlink receiving state of the current mixed group calling is not required to be changed, namely the receiving of the current mixed group downlink calling is not influenced.
In addition, it should be noted herein that when the dual-mode terminal detects that the reliability of uploading the group call voice through the narrow-band mode is lower than the preset threshold, after sending an uplink call right switching request message requesting to switch the uplink call right from the narrow-band mode to the wide-band mode to the network side, the dual-mode terminal needs to continue uploading the group call voice through the narrow-band mode; certainly, after the dual-mode terminal switches the uplink speech right from the narrowband mode to the broadband mode according to the speech right switching instruction, the dual-mode terminal may simultaneously upload the group call speech through the narrowband mode and the broadband mode, and stop uploading the group call speech through the narrowband mode after a preset time period.
Therefore, after the dual-mode terminal sends the uplink speaking right switching request message, the group calling voice is continuously uploaded through the narrow-band mode, and uninterrupted transmission of the group calling voice is ensured; in addition, after the dual-mode terminal switches the uplink speech right to the broadband mode, the group calling speech is uploaded through the narrowband mode and the broadband mode at the same time, and the group calling speech is stopped being uploaded through the narrowband mode after the preset time period, so that the uploading stability of the group calling speech in the speech right switching time period is ensured, and the smooth transmission process of the group calling speech is further ensured.
In addition, further, when the dual-mode terminal detects that the reliability of the group calling voice uploaded through the narrow-band mode is lower than a preset threshold, after sending an uplink talk right switching request message requesting to switch the uplink talk right from the narrow-band mode to the wide-band mode to the network side, the talk right switching method further includes:
receiving a speaking right switching forbidding instruction which is sent by the network side according to the upstream speaking right switching request message and forbids switching of the upstream speaking right from a narrow-band mode to a wide-band mode, and continuously uploading group calling voice through the narrow-band mode according to the speaking right switching forbidding instruction; wherein the content of the first and second substances,
the call right switching forbidding instruction is a P _ PROTECT message, and PK in the P _ PROTECT message is defined as indicating that the uplink call right switching is forbidden;
and the speaking right switching forbidding instruction is sent after the network side receives the uplink speaking right switching request message and detects that the broadband module does not meet the uplink speaking right switching condition.
In this way, by defining the PK value as the P _ PROTECT message for forbidding the uplink speaking right switching as the speaking right forbidding switching instruction, the application of the dual-mode terminal to the speaking right switching and the signaling message response can be realized under the condition of not changing the conventional signaling mechanism and protocol of PDT.
In addition, specifically, the talk right prohibition switching command can also be broadcast in the TS coverage area where the group call voice is located. Therefore, the broadcast mode does not change the original P _ PROTECT message sending mechanism of PDT, the same group of called parties can also receive the message and can judge the message through the PK value, and the downlink receiving state of the current mixed group calling is not required to be changed, namely the receiving of the current mixed group downlink calling is not influenced.
The following describes the whole talk right switching process in this embodiment with reference to fig. 2, where the whole talk right switching process is as follows:
step 1: the current uplink speaking right is positioned in a narrow-band mode of the dual-mode terminal;
step 2: the broadband mode of the dual-mode terminal sends a speech right applying queuing message NAS to a network side: FLOOR REQUEST, and receiving the call waiting message NAS replied by the network side: FLOOR WAIT to queue the FLOOR within the broadband module.
And step 3: when the dual-mode terminal detects that the reliability of uploading the group calling voice through the narrow-band mode is lower than a preset threshold, the dual-mode terminal sends an uplink call right switching request message P _ MAINT (saddr is msl, taddr is TSI, mk is 1112) requesting to switch the uplink call right from the narrow-band mode to the wide-band mode to the network side, and at the moment, the dual-mode terminal continues uploading the group calling voice through the narrow-band mode.
And 4, step 4: the network side sends a speaking right authorization message NAS to the broadband mode: FLOOR GRANT, and the broadband mode and the network side try to establish a dedicated bearer, after establishing the bearer, the dual-mode terminal sends a talk right authorization response message NAS to the network side through the broadband mode: FLOOR GRANT ACK. Specifically, at this time, the network side receives the homologous group call voice uploaded by the dual-mode terminal through the broadband mode and the narrowband mode at the same time in a preset time period.
And 5: after detecting that the broadband mode meets the uplink talk right switching condition, the network side sends a talk right switching instruction P _ process (saddr is TSI, taddr is msl, PK is 1102) to the narrowband mode of the dual-mode terminal, that is, P _ process (PK is allowed to switch).
And when the narrow-band module of the dual-mode terminal receives the speaking right switching instruction, the narrow-band module stops sending the group calling voice, and the group calling uplink mode speaking right switching is completed.
It should be noted that, if the network side detects that the broadband mode transmission of the dual-mode terminal is abnormal, for example, when the network side detects that the broadband mode uplink transmission cannot be reliably established before the preset timer expires, a call right prohibition switching instruction, that is, P _ profile (PK is prohibited to switch), is sent to the dual-mode terminal to instruct to prohibit switching the uplink call right from the narrowband mode to the broadband mode, at this time, the dual-mode terminal continues to perform uplink group call generation using the narrowband mode, and the broadband mode will perform queuing application common knowledge again under the management of the network side. In addition, if the preset timer times out, the narrowband mode and the broadband mode of the dual-mode terminal cannot reliably work, and the network side can stop the uplink right of the dual-mode terminal.
Thus, the embodiment of the invention realizes the speech right switching process from the narrow-band mode to the wide-band mode of the dual-mode terminal through the speech right switching process, realizes the application of the dual-mode terminal to the speech right switching and the response of the signaling message under the condition of not changing the conventional PDT signaling mechanism and protocol, ensures the smooth switching of the uplink group call of the dual-mode terminal from the narrow-band mode to the wide-band mode, and simultaneously ensures that the mixed group narrow-band side member continues to receive the group downlink group call voice service without being influenced.
In addition, as shown in fig. 3, a flowchart of steps of a talk right switching method applied to a network side in the embodiment of the present invention is shown, where the method includes the following steps:
step 301: receiving an uplink speaking right switching request message which is sent by a dual-mode terminal and requests to switch the uplink speaking right from a narrow-band die to a wide-band die, and detecting whether the wide-band die meets an uplink speaking right switching condition or not after receiving the uplink speaking right switching request message.
In this step, specifically, the dual-mode terminal includes a narrowband mode and a broadband mode, and when the dual-mode terminal detects that the reliability of the group call voice uploaded through the narrowband mode is lower than a preset threshold, the dual-mode terminal sends an uplink right switching request message to the network side, and at this time, the network side receives the uplink right switching request message sent by the dual-mode terminal to switch the uplink right from the narrowband mode to the broadband mode, and detects whether the broadband mode meets an uplink right switching condition after receiving the uplink right switching request message.
Specifically, whether the broadband mode meets the uplink talk right switching condition or not may be detected, that is, whether the broadband mode performs talk right queuing in the broadband module is detected, and if it is detected that the broadband mode performs talk right queuing in the broadband module, it is determined that the broadband mode meets the uplink talk right switching condition.
Step 302: and when detecting that the broadband mode meets the uplink speaking right switching condition, sending a speaking right switching instruction for indicating that the uplink speaking right is allowed to be switched from the narrowband die to the broadband mode to the dual-mode terminal according to the uplink speaking right switching request message.
In this step, specifically, when the network side detects that the broadband mode satisfies the uplink talk right switching condition, the network side may send, to the dual-mode terminal, a talk right switching instruction indicating that the uplink talk right is allowed to be switched from the narrowband mode to the broadband mode according to the uplink talk right switching request message, so that the dual-mode terminal switches the uplink talk right from the narrowband mode to the broadband mode according to the talk right switching instruction.
Thus, the network side in this embodiment receives an uplink call right switching request message that requests the dual-mode terminal to switch the uplink call right from the narrowband die to the broadband die, and when detecting that the broadband die satisfies the uplink call right switching condition, sends a call right switching instruction that indicates that the uplink call right is allowed to be switched from the narrowband die to the broadband die to the dual-mode terminal, so that the dual-mode terminal performs call right switching according to the call right switching instruction, thereby implementing call right switching between the narrowband die and the broadband die in the dual-mode terminal, and ensuring that the broadband die can continue uplink group call when the narrowband die of the dual-mode terminal cannot normally upload group call voice, thereby ensuring smooth proceeding of the uplink group call process.
Further, the uplink speaking right switching request message can be a P _ MAINT message, and a reserved value of a cell in the P _ MAINT message is defined as a request for switching the uplink speaking right from a narrowband die to a wideband die; the talk burst switch command is a P _ PROTECT message, and the PK in the P _ PROTECT message is defined to indicate that the uplink talk burst switch is allowed.
For example, cell mk in the P _ MAINT message may be 1112, and this value is defined to indicate that the upstream floor is requested to be switched from narrowband to wideband; in addition, PK in the P _ PROTECT message allows conversion, i.e. indicates that the dual-mode terminal is allowed to perform uplink right conversion.
Therefore, by defining the cell in the P _ MAINT message, determining the defined P _ MAINT message as the uplink talk right switching request message, and by performing the permission switching definition on PK in the P _ PROTECT message, and determining the defined P _ PROTECT message as the talk right switching instruction, the application of the dual-mode terminal to talk right switching and the response of the signaling message can be realized under the condition of not changing the conventional signaling mechanism and protocol of PDT, the smooth switching of the uplink group call of the dual-mode terminal from a narrowband mode to a broadband mode is ensured, and meanwhile, the group of downlink group call voice service is continuously received without influencing the members at the narrowband side of a mixed group.
In addition, further, when the network side sends a talk right switching instruction indicating that the uplink talk right is allowed to be switched from the narrowband mode to the broadband mode to the dual-mode terminal, the talk right switching instruction may be broadcast in a coverage area of a cluster base station TS where the group call voice is located, so that the dual-mode terminal receives the talk right switching instruction. Therefore, the broadcast mode does not change the original P _ PROTECT message sending mechanism of PDT, the same group of called parties can also receive the message and can judge the message through the PK value, and the downlink receiving state of the current mixed group calling is not required to be changed, namely the receiving of the current mixed group downlink calling is not influenced.
In addition, specifically, after detecting whether the broadband mode satisfies the uplink talk right switching condition, the network side may further send, according to the uplink talk right switching request message, a talk right switching prohibition instruction instructing to prohibit switching the uplink talk right from the narrowband mode to the broadband mode to the dual-mode terminal when detecting that the broadband mode does not satisfy the uplink talk right switching condition; wherein the content of the first and second substances,
the call right switching prohibition instruction is a P _ PROTECT message, and PK in the P _ PROTECT message is defined to indicate that uplink call right switching is prohibited.
In this way, by defining the PK value as the P _ PROTECT message for forbidding the uplink speaking right switching as the speaking right forbidding switching instruction, the application of the dual-mode terminal to the speaking right switching and the signaling message response can be realized under the condition of not changing the conventional signaling mechanism and protocol of PDT.
In addition, specifically, the talk right prohibition switching command can also be broadcast in the TS coverage area where the group call voice is located. Therefore, the broadcast mode does not change the original P _ PROTECT message sending mechanism of PDT, the same group of called parties can also receive the message and can judge the message through the PK value, and the downlink receiving state of the current mixed group calling is not required to be changed, namely the receiving of the current mixed group downlink calling is not influenced.
In addition, it should be noted that, the overall procedure of the talk right switching may refer to fig. 2, and is not described again here.
Thus, in this embodiment, by receiving the uplink talk right switching request message sent by the dual-mode terminal and feeding back the talk right switching instruction to the dual-mode terminal, the talk right switching process from the narrow-band mode to the wide-band mode of the dual-mode terminal is realized, so that the application of the dual-mode terminal to the talk right switching and the response of the signaling message can be realized without changing the existing signaling mechanism and protocol of PDT, the smooth switching of the uplink group call from the narrow-band mode to the wide-band mode of the dual-mode terminal is ensured, and meanwhile, the group of downlink group call voice services can be continuously received without affecting the members on the narrow-band side of the hybrid group.
