As shown in FIG. 4A, the access device shown in FIG. 4A includes an utterance driving circuit 41 and an access device control center 42, which cannot emit sound by itself, and needs to be connected to an external electroacoustic conversion sound generator to play voice, and is external to the sounding device portion. The access device shown in FIG. 4B is internally provided with an utterance driving circuit 41 and an electroacoustic conversion sound generator 43, which are built into the sounding device, and therefore, The access device itself can play voice. The sound source can come from the data stream sent by the network, or from the local voice warehouse A, that is, the storage circuit integrated in the sounding drive circuit, or from the local voice warehouse B, that is, the internal storage device.

FIG. 4C is a schematic structural diagram of an embodiment of a system for playing voice by using an access device according to the present invention. The system includes a network sounding control device 45 and an access device 46. The access device 46 controls the sounding device 47 to sound according to a network message sent by the network sounding control device 45. In other words, the system for playing voice by using the access device may include the sounding device and any one of the above embodiments in which the sounding device is not provided with the sounding device, and the access device drives the sounding device by the control signal. When the sound source is externally placed on the access device, the system may further comprise an external storage device storing the voice data; when the access device is triggered by the network message to generate the sounding control signal, the system may further comprise a network sounding control device, such as accessing Gateway (AG), Network Time Protocol (NTP) server, management network element, etc. When the access gateway sends a terminal access message or a timing message to the access device, or when the NTP server sends a network time message to the access device, or when the management network element sends an alarm or a service message to the access device, the access device is triggered to generate The control signal drives the sounding device to sound. When the access device has a sounding device built in, the system is composed of an access device and a network sounding control device, wherein the access device has been described in detail in the above embodiment, and the network sounding control device can be similar to the description in the above system.

The method of playing voice by the access device may require the participation of the network or the participation of the network. When network participation is required, that is, the network has voiced services. For the convenience of description, it can be referred to as network voice service. It can be a public service controlled by the operator, such as an earthquake alarm, a typhoon alarm, etc., or it can be customized by the user, such as an hourly chime, morning. Wake up, birthday songs and other services, can also be public affairs of government departments such as air defense alarms, and even in the form of advertising carriers in exchange for lower fees for users, such as: If the user is willing to open the advertising function for an hour, you can How much traffic fee is reduced and so on. The above-mentioned voices other than the public service business are collectively referred to as customized services. The application can be customized to the upper management device in various ways. For example, when opening an account, usually call or go to the business hall to apply, directly through the software interface customization, etc. Wait. After customization, the voice service will be triggered under certain conditions such as time trigger, event trigger, and so on. When triggered, the upper management device sends a specific The command, the access device emits a specific sound, music or voice according to a specific command. The specific instructions of the upper management device may contain rich information; the access device may respond accordingly according to the relevant agreement agreed in advance. When no network participation is required, the service that uses the access device to vocalize is simply referred to as a non-network voice service, such as a timer. At this time, the user may also pass the access device in the local personal computer (PC) without going through the operator. The software interface directly controls the voice service, and can also control the voice service through the display and input panels or buttons of the access device. For the vocal service such as hourly chime, wake up in the morning, etc., there may be network participation or no network participation; if the time requirement is not strict, it can be treated as a non-network vocal service, and may have to calibrate the time by itself; The time requirement is strict and you don't want to manually correct the time. You can use the network to accurately time the time. The trigger mode can be the network side trigger or the local trigger. At this time, the time between the access device and the AG device is synchronized. In terms of network efficiency, local triggering is better.

The network voice service may be a non-time type trigger, such as an event trigger, or a time type trigger, which requires network cooperation; the non-network voice service is only a time type trigger, and does not involve the network side, in other words, the time class. The trigger can be timed via the network and then selected to trigger on the local or network side. The source of the sound may be sent by the network side to the access device, such as a network broadcast, a network advertisement, or the like, or may be preset in the access device such as a doorbell, a morning chicken, and the like. Considering network congestion, when some relatively fixed sound sources are preset inside the access device, the network only needs to be responsible for configuration or configuration plus triggering, which can save bandwidth.

FIG. 5 is a schematic diagram of networking in an embodiment of a method for playing voice by using an access device, where an access device, an AP gateway (AG), and an AP management device (0MC) are main key network elements. The access device provides UMTS wireless access, including functions such as wireless modem and radio resource management. The 0MC provides centralized management and maintenance of the AP.

The method for playing the voice by the access device of the present invention can be applied to scenes such as reminders and alarms. FIG. 6 is a flowchart of Embodiment 1 of a method for playing a voice by using an access device. In this embodiment, when a user of a terminal UE accesses or removes a range covered by an access device, the access device may sound a prompt according to the setting. To remind the access device owner. In this way, the access device even has a doorbell Features. For example, the access device is pre-set by the local computer, and the sounding device is triggered to sound for a specific terminal that enters the coverage area of the access device. The specific terminal is a terminal that is set by the access device user and can trigger the sounding device to sound. For other terminals, it is not necessary to avoid the interference problem caused by unnecessary sound. As shown in FIG. 7, when the person holding the UE is at the door of the door, if the doorbell is not pressed, his mobile phone will signal the access device 71 to give a prompt to inform him of the arrival. Take the 3GPP Femto system as an example, and its signaling flow chart is shown in Figure 8. As shown in FIG. 6, and in conjunction with FIG. 8, the method for playing voice by using an access device specifically includes the following steps:

Step 61: When the UE enters the coverage area of the access device, the UE initiates a connection request message 81, such as a message “LAU/RAU Reques t/At tach Reques t”, and the message is finally sent to the AG;

Step 62: The AG returns a connection response message, such as a connection accept message 82 "LAU/RAU Reque s t/At tach Accept", to the access device in response to the received "LAU/RAU Reques t/At tach Reques t" message;

Step 63: The AP receives the "LAU/RAU Accept/At tach Accept" message sent by the AG, generates an utterance control signal, turns on the sounding device, plays the sound content, and completes the prompt function. The sound content of the sound can be stored in the access device. For example, a sound source such as a doorbell is integrated inside the access device, and the voice prompt content of the sound source can also be customized by the user of the access device.

Step 61: Step 62 is an existing standard procedure of the 3GPP, which is used for the mobile phone to initiate routing area and location area update, and other access devices of different standards can be similarly processed. With the existing signaling process, the access device can learn that the UE performs the location area and the routing area update by parsing, thereby driving the sounding device to sound.

Further, the access device may also determine whether the connection response message, such as the "LAU/RAU Reques t / At tach Accept" message, is caused by a specific terminal set in advance, and if so, generate an audible control signal to trigger the sounding device to emit a prompt sound; otherwise , the sounding control signal is not generated, and the sounding device is not triggered, thereby ensuring that the access device can selectively emit the prompt sound.

The access device can also be used for network reminders such as on-time reporting, wake-up reminders, etc. As shown in FIG. 9, the access device can include a sounding device. At this point, other network devices are required. The time of the network is very fine Precise, no user calibration is required. The access device 91 can periodically trigger the sounding device to sound an alarm, as shown in FIG. 10, including the following process:

Step 101: The access device is powered on and initialized.

Step 102: After the initialization operation is completed after the access device is powered on, establish a transmission connection with the AG (the intermediate device may pass other transmission devices);

Step 103: The access device obtains accurate network time from the AG (it may also obtain time from other devices such as the network time protocol NTP server);

Step 104: Step 105: The access device may start a timer according to a user setting such as a fixed time report, a wake up alarm, and the like. This setting can be configured by the network side or by the AP locally, as determined by the operator;

Step 1 06. When the timer reaches the set time, the triggering access device generates a sounding control signal, and the sounding control signal is used to open the sounding device to play the sound, such as "now X point X minutes X seconds", etc., to complete the sound alarm such as fixed time alarm, alarm clock, etc. Features.

The access device 91 can also be triggered by the network side to control the sounding device to sound an alarm, as shown in Figure 11, including the following process:

Step 111: After the access device is powered on, the initialization operation is completed, and the AG establishes a transmission connection (the intermediate transmission device may pass through other transmission devices);

Step 112: The AG can start the timer according to the setting of the user, such as the fixed time report, the wake-up alarm, etc. Step 11 3. When the timer reaches the set time, the AG notifies the access device by multicast, broadcast or unicast;

Step 114: When the access device receives the time message sent by the AG, the sounding control signal is generated, and the sounding device is turned on by the sounding control signal, such as “now X point X minutes X seconds”.

In the above-mentioned reminder embodiment, the access device can obtain the precise time, whether it is obtained from the AG or the NTP server (the server providing the real-time clock), can be triggered automatically or triggered by the network element such as the AG, thereby saving network resources. And easy to operate. AG AG trigger is just an example. To set the timer period, you only need to configure the timing trigger signal of each access device on the AG. Information such as trigger time, cycle, etc. The above reminder service is generally customized in the upper management device, and can be applied in various ways, such as when opening an account, usually calling or going to the business hall.

The use of access devices to play voices can also be used for public services such as alarms. For example, in some earthquake-prone countries and regions, warnings are generally issued about 10 seconds before the earthquake. As shown in FIG. 12 and FIG. 13 , a special command can be sent to the access device 121 through an upper management device, such as an AP management device. After receiving the command, the access device 121 generates an audible control signal, and controls the built-in or The external sounding device emits a corresponding prompt sound, such as an alarm sound. Similarly, the access device 121 can also be used to generate a typhoon alarm, or an air defense alarm, and the like. The special instruction may be a message defined between the AP management device (AP Manager) 1 31 and the access device, and has the same message format as the other AP management device 1 31 and the access device, except that the content is different; different messages may be defined. Trigger the access device to play different sounds. You can also trigger the access device to play different sounds by setting the parameter identification to a different value in a message, as long as the access device can recognize it.

Before the earthquake, typhoon and other disasters come, the relevant government departments will inform the operators of the disaster news; the operator will input the disaster message to the centralized network management device AP Manager of the access device, ie, the 0MC, and then trigger the access device to send an alarm through the network. As shown in FIG. 14, the method includes the following steps: Step 141: The AP management device (Manager) broadcasts the disaster alert prompt information to each online connected access device.

Step 142: After receiving the disaster alarm prompt information, that is, the predefined message, the access device generates a sounding control signal, and selects a corresponding alarm sound source according to the alarm content. If the earthquake alarm prompt information is received, the corresponding earthquake alarm is selected. Sound data; if a typhoon warning message is received, the corresponding typhoon alarm sound data is selected;

Step 143: The sounding control signal acts on the sounding device, and the sounding device is turned on, and the sounding device plays the corresponding alarm sound selected by the access device to complete the alarm, so that the user who uses the access device can hear the alarm sound in time to obtain emergency measures. Such as the emergency evacuation of houses, etc., to reduce the loss of personnel and property. The file of the alarm sound source is preset in the AP or written on the storage device such as FLASH, and is read by the access device. The access device can control the sounding device to repeat in a certain time according to the content of the prompt information. Play. The sound source can be made into a more intelligent voice prompt, such as playing a sound like "Emergency Earthquake Alarm: XXX,".

The voice played by the access device can also be used for services such as network broadcast and network advertisement. As shown in FIG. 15, the upper management device sends a broadcast service control message and a message including the audio data content to the access device 151 through the network, where the broadcast control is performed. The service message triggers the access device 151 to generate an utterance control signal, and the access device 151 converts the audio data content into data that can be converted and played by the sounding device, and sends the data to the sounding device, and the sounding device plays the network broadcast under the control of the utterance control signal. At this time, the access device 151 has a function of a radio through which the user can receive a global network broadcast. The difference is that the information of the access device 151 comes from the network, not the low frequency radio waves in the air. Similarly, the upper management device can trigger the access device to control the sounding device to play the voice advertisement by sending the advertisement service control message and the message containing the audio data content. As shown in FIG. 16, the access device 161 can play the voice advertisement. In this way, the access device can be used as an advertising carrier in exchange for a lower fee for the user, such as: if the user is willing to open the voice advertising function for one hour, reduce the certain traffic fee, and the like.
