Description

Method for automatically selecting a mobile or fixed network by a multimode wireless voice terminal device

The present invention relates to the field of multimode wireless voice terminal equipment and telephone communication technology in wireless communication, and in particular to a method of selecting a mobile network or a fixed network when making a telephone call.

Background technique

At present, mobile phones (mainly including GSM phones, 3G phones, WiMAX phones, etc.) are widely popular, but they still have limitations. First, although the mobile phone network covers a wide range, the signals of the mobile network are indoors, and the blind areas such as underground passages will still be weak. Secondly, in order to cover remote areas and mountainous areas, the cost of constructing a mobile network base station is quite expensive; Third, the cost of communication using mobile networks is still high. At the same time, cheap landline/data networks cover a wide range of areas, and mobile phones can be connected to fixed networks via short-range wireless technologies (such as Bluetooth, WLAN, UWB, wireless VSB, etc.) over fixed network calls. The biggest advantages of fixed networks over mobile networks are: stable and reliable signals, low cost, and low communication costs. We will be able to access long-distance mobile networks, or simultaneously access short-range wireless technology to access fixed-line voice terminals called multi-mode wireless voice terminals, which is a new type of wireless voice generated by the development of short-range wireless technology. Terminal Equipment.

At present, the more mature solutions for adding short-range wireless access technologies to mobile phones include Bluetooth and WLAN. Bluetooth is a short-range wireless communication technology that operates in the 2.4 GHz ISM (Industrial-Science-Medical) band. With Bluetooth technology, devices can be connected in a cost-effective manner. The Special Interest Group (SIG) in its definition of Cordless Phone Profile proposes a way to implement wireless voice terminal equipment access to a fixed network using Bluetooth technology. Both the gateway and the wireless voice terminal device are equipped with a Bluetooth wireless transceiver module, which uses Bluetooth for voice and control signaling transmission. The gateway is connected to a fixed network. Once the wireless voice terminal device enters the RF range of the gateway, it establishes a wireless connection with the gateway. The gateway accesses the fixed network. WLAN is also a short-range wireless communication technology. It can establish an IP connection between a wireless voice terminal device and a gateway through a WLAN wireless transceiver module. The gateway is connected to a fixed data network, and the wireless voice terminal device accesses the fixed data network through the gateway. . Other short-range wireless technologies, such as wireless USB and UWB, can also set wireless voice terminals with their corresponding standards. The device is connected to the fixed network through the gateway.

In the current solution, when a multimode wireless voice terminal device is connected to a gateway and is dialed/received through a multimode wireless voice terminal device, in general, the phone will be dialed/received through a fixed network connected to the gateway. However, in actual use, some countries/local regulations require certain free special service numbers, such as certain emergency call numbers, to be dialed through the mobile network. Moreover, according to the different tariff policies of network operators, there are still some numbers that directly move the mobile network to save money more than the fixed network. Taking China Mobile's mobile network as an example, when dialing the I860 customer service call of the communication company, it is free to dial through the mobile network, which is obviously more cost-effective than dialing through a fixed network, and when using its family number service, by moving The network can save money by making and receiving calls from the set family number. In addition, when the multimode wireless voice terminal device is connected to the gateway, it is not possible to make/receive calls over the fixed network in the event that the gateway is busy.

The above situation indicates: When making a call, it is not possible to simply select a fixed network according to the connection between the multimode wireless voice terminal device and the gateway, but to make further judgment according to the number in the current call and the working state of the current gateway. Flexibly determine whether a call is made over a fixed network or a mobile network. Currently, it has appeared, for example, to provide a shortcut button or menu on the terminal, so that the user can quickly select a scheme for switching to a fixed network or a mobile network. However, although this solution can achieve the above objectives, it is inconvenient for the user to use. If the above-mentioned judging process can be performed automatically, without the user's intervention, the dialing habit of the existing user may not be changed, so that the user only needs to dial the number. This should be advantageous.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a flow chart for automatically selecting a mobile network or a fixed network when a multi-mode wireless voice terminal device initiates a telephone call in accordance with the present invention.

Since the multimode wireless voice terminal device can be connected to the mobile network and the fixed network, usually one of the networks will be designated as the default network.

In accordance with an embodiment of the present invention, when the multimode wireless voice terminal device initiates a telephone call S100, it first determines the currently set default network S110. Here, it is assumed that the default network is a fixed network.

After determining the default network, the multi-mode wireless voice terminal device matches/filters the call number stored in the multi-mode wireless voice terminal device with the called number (hereinafter referred to as the called number) S120, S180, so that the specific The call corresponding to the number is carried out via a specific network. The call rules and matching/filtering methods can take many forms and will be described below with reference to FIG.

If the called number satisfies the calling rule, for example, matches a specific number or a specific prefix in the multi-mode wireless voice terminal device, indicating that the call corresponding to the called number must be performed through another network other than the default network, In this scenario, the other network is a mobile network, and the multi-mode wireless voice terminal device switches to a corresponding mobile network communication module to initiate a telephone call S190 through the mobile network. If the called number does not match the specific number or the specific prefix in the voice terminal, or the matching result indicates that the call must be made through the fixed network, the call is directly initiated through the fixed network, that is, the set default network. Called by phone.

After determining to initiate a telephone call through the fixed network, it may also be determined whether the multimode wireless voice terminal device is connected to the gateway S130; if not connected, the call is still passed through the mobile network S190. If the connection is already connected, you need to check the status S140 of the current gateway. If the gateway is not busy, the telephone call S170 is initiated through the fixed network; if the gateway is busy, it is checked whether the gateway busy time call is set to pass through the mobile network for S150. If it has been set, the call is changed to S190 through the mobile network. If not set, the user is prompted: The gateway is busy, and the call cannot be successful S160. Similarly, if it is determined that the default network is the mobile network S110, then after the matching/filtering S180 is performed on the called number, if the result of the matching/filtering is to pass through the fixed network, the network communication module is switched and Steering through Step S130 of fixing the network; otherwise, a telephone call S190 is initiated through the mobile network.

2 is a flow chart of automatically selecting a mobile network or a fixed network when a multimode wireless voice terminal device answers a telephone call. The multimode wireless voice terminal device can be connected to a mobile network or a fixed network, and one of the mobile network or the fixed network is set as the default listening network.

Upon receiving the incoming call request, the multimode wireless voice terminal device first determines whether the incoming call request arrives at S210 via the fixed network or the mobile network.

If the incoming call request is via a gateway, i.e., a fixed network arrives, the incoming call S270 is directly ringed, answered, or rejected by the fixed network.

If the incoming call request is reached via the mobile network, then the current default answering network setting S220 of the multimode wireless voice terminal device is determined. If the default network is a fixed network, the calling number of the call is matched/filtered S220, for example, the matching/filtering of the calling number is performed against a specific number or a specific prefix in the multimode wireless voice terminal. The result is that by moving the network, instead of ringing, answering, or rejecting incoming calls through the mobile network, S290 is called. If the matching/filtering result is to accept an incoming call through the fixed network, it can also be determined whether the multimode wireless voice terminal device is connected to the gateway S240. If there is no connection, the call still passes through the mobile network S290; if it is already connected, it needs to check the status of the current gateway S250. If the gateway is not busy, the incoming call can be transferred to the gateway S260 via a mobile network command, such as a busy call transfer, and the multimode wireless voice terminal device rings, answers, or rejects the incoming call through the fixed network via the gateway. S270. If the gateway is busy, it still answers or rejects the incoming call S290 via the mobile network.

If the default mobile network/fixed network setting S220 of the multimode wireless voice terminal is determined, the default is to move the network, and the calling number of the call is matched and filtered S2 ⁸⁰⁰ . If the result is matched/filtered with a specific number or a specific prefix within the voice terminal, the result is that the fixed network is required to switch to the step S240 of making a call through the fixed network; otherwise, the incoming call S290 is ringed, answered or rejected by the mobile network.

Figure 3 is a flow chart detailing the matching/filtering of call numbers according to call rules in accordance with the present invention.

Here, the call rule specifies the particular network through which the call passes for a particular calling number, which can have multiple matching/filtering options. For example, the calling number can be checked, including the calling number or the called number, whether it matches the pre-registered specific number S300. If the calling number is identical to any one of the specific numbers, the indicating number matches, and the matching is matched. Set, select by moving or fixing the network S350.

Alternatively, it can be checked whether the calling number matches the pre-registered specific number prefix S310. If the first few digits of the calling number starting from the first digit are identical to any one of the specific number prefixes, the number prefix matches, according to the prefix matching setting, Select through the mobile or fixed network S350.

It is also possible to check whether the calling number is the same as the pre-registered specific number filtering prefix S320. If the first few digits of the calling number starting from the first digit are exactly the same as any one of the specific number filtering prefixes, the number prefix filtering is performed on the calling number. That is, the same number prefix portion as a certain filtering prefix is removed from the calling number, and the remaining number is the real calling number, and the mobile or fixed network S350 is selected for the made call according to the filtering setting.

Alternatively, it can be checked whether the calling number matches the pre-registered specific number or number prefix bound with the time period, and the number filtering prefix matches S330. If it matches, the matching/filtering setting is specified to specify that the call is selected within a certain period of time. By moving or fixing the network S350.

Alternatively, an option is added to the telephone contact record of the multimode wireless voice terminal device to specify whether the preferred preferred network for the calling number is a mobile network or a fixed network; this is a specific form of number matching.

The call number, the specific number prefix, and the specific number filter prefix may be strings that are combined in any order by numbers, letters, or special symbols.

If the calling number does not match or/or is different from the pre-registered specific number or number prefix, number filtering prefix, then for the calling number, the mobile or fixed network is selected for communication S340 according to the current default settings.

By number matching/filtering, the user can dial directly, and the number automatically selects the mobile/fixed network by number matching. Or add the specified filter prefix before the number you want to dial. For example, ' # #, , means dialing the number through the fixed network, and ' # # will be removed when dialing. Some mobile network service providers offer to make/receive calls for free during a certain period of time, such as from 22:00 to 6:00 in the morning, then set the filtering prefix ' # #, , the calling number with the filtering prefix at this time All of the segments will pass through the mobile network. For answering calls, the user can set, for a certain number, all answered through the mobile network.

For the method of automatically selecting a network, the expansion can be further improved. For example, when detecting whether the gateway is connected to the terminal, signal strength detection can be added at the same time, and it can be set that when the signal strength is lower than a certain limit, it is considered that the connection between the gateway and the terminal is unavailable, and thus two Not connected. In addition, before the multi-mode wireless voice terminal device forwards the call to the gateway, the multi-mode wireless voice terminal device can first detect whether the gateway supports calling the ring-only multi-mode wireless voice terminal device by using a special extension command, if not Support, you can not make call transfer.

The short-range wireless technology described in the context of the present invention may not be limited to the listed WLAN, Bluetooth, UWB, and Wireless USB, and may be other short-range wireless access methods. The long-distance wireless can be not limited to the listed GSM, 3G, WiMAX, etc., or other long-distance wireless access methods, such as the PHS PHS or the next-generation wireless 4G.

While the invention has been shown and described with respect to the preferred embodiments of the embodiments of the invention Various changes in details.
