Description

Method for registering in a database, terminal, access point, database and communication system

technical field

The invention relates to the communication field, in particular to a method for registering in a database, a terminal, an access point, a database and a communication system.

Background technique

Cognitive Radio (CR) is the most promising technology to solve the current shortage of spectrum resources. The current spectrum usage policy is fixed allocation, that is, the government allocates fixed resources for specific services of specific users, such as television, radio, radar, navigation, etc., all use fixed frequency points, some of which are not used all the time, nor are they everywhere They are all in use, so there are certain time periods and certain geographical locations, and some frequency bands are not fully used. Studies have shown that a large number of fixedly allocated frequency bands are not fully used, which has caused a huge increase in spectrum resources. waste. By sensing the wireless spectrum environment, cognitive radio can discover these unoccupied frequency bands that appear anytime and anywhere, and dynamically access these frequency bands without interfering with primary users (Primary User, PU, that is, the original fixedly allocated frequency users). Realize the use of every corner to improve spectrum utilization.

In order to achieve the above purpose, currently major standard organizations and regulatory organizations, such as the Federal Communications Commission (Federal Communications Commission, FCC) in the United States, the European Conference of Postal and Telecommunications Administrations (CEPT) in Europe, and the Office of Communications (Office of Communications) in the United Kingdom. of Communications, OFCOM), are determined to standardize CR technology. Taking TV as an example, the working frequency band of digital TV in China is 470MHz~806MHz. Since digital TV transmission towers have the characteristics of geographic multiplexing, for example, the TV transmission tower working in Beijing works at 500MHz, while the transmission tower in Chengdu will work at Other frequency bands, so 500MHz is an unoccupied frequency band for the transmission towers in Chengdu. Cognitive radio devices can use these unoccupied frequency bands by identifying the current radio environment through CR technology.

In order to identify the current radio environment, each of the above regulatory organizations has developed a database (Database, DB), which stores all spectrum usage information. Taking the TV spectrum as an example, the spectrum information in the database includes the location of the TV tower, the frequency band used, the coverage area, etc. Cognitive devices can obtain the frequency spectrum of the current location by querying the database, so as to use frequency bands that are not currently used.

In order to obtain the right to use the spectrum provided by the database, the cognitive device must first register with the database, and only the registered device can use the spectrum resources.

Another method for registering in the database provided by the embodiment of the present invention is based on the data plane and on the database side, which is the same as the method shown in FIG. 3 and will not be described again.

An embodiment of the present invention provides a method for registering in a database. By sending a registration request message to an access point, and converting the registration request message into a data format through the access point and sending it to the database, the user terminal can be registered in the database. , so that the user terminal can obtain the right to use the spectrum provided by the database, so that the user terminal can use the spectrum resource.

Another embodiment of the present invention provides a method for registering in a database, as shown in Figure 6, including:

S601. The user terminal performs encryption authorization authentication processing.

Exemplarily, in an LTE (Long Term Evolution, Long Term Evolution) network or a WIFI (Wireless Fidelity, wireless network) network, the user terminal first initiates an association request to the network after being turned on, and performs encryption authorization authentication.

For the control plane process, the user terminal can initiate a registration request to the database after completing the encryption authorization authentication, where the database can be a White Space Data Base (WSDB). The advantage of doing this is that the air interface (Air Interface, AI) is protected after the encryption authorization authentication is completed, and the registration process at this time is more secure and reliable.

Wherein, the foregoing control plane refers to messages transmitted between network elements in a signaling format.

S602. The user terminal sends a registration request message to the access point.

Since different protocols are adopted from the user terminal to the base station, and from the base station to the WSDB, the format of the transmitted message is also different. Therefore, the user terminal cannot directly initiate a registration request to the WSDB after completing the encryption authorization authentication. The entry point sends a registration request message in a signaling format, where the registration request message includes a message identifier, user terminal type information, user terminal identifier, fixed or handheld identifier, and antenna height information.

S603. The access point converts the registration request message from a signaling format to a data format.

Specifically, after receiving the registration request message, the access point can firstly identify that the message is a request message for registering with the WSDB proposed by the user terminal according to the message identifier in the registration request message, and then convert the registration request message from the signaling format Convert to data format.

It is worth mentioning that in an LTE network, the access point may be a base station, such as an eNode B (evolved base station), and in a WIFI network, the access point may be an AP (Access Point, AP).

S604. The access point sends the registration request message to the database.

Specifically, for different implementations or different application scenarios, the process of "sending the registration request message to the database" is also different. For example, in the control plane process, it includes but is not limited to the following application scenarios.

For the following situations: 1. eNode B of LTE network; 2. AP of enterprise-level WIFI network; 3. When the WIFI access point in the converged network is a trusted AP, the access point sends the registration request message to the trusted AP. After the command format is converted into a data format, the registered request message after the format conversion is directly sent to WSDB, and no relay is required during the sending process. Wherein, the above-mentioned converged network may be composed of various networks, for example, the converged network may include an LTE network, a WIFI network, and the like.

However, when the WIFI access point in the converged network is an untrusted AP, as shown in Figure 7, after the access point converts the registration request message from the signaling format to the data format, it needs to convert the registered registration request The message is sent to the ePDG (evolved Packet Data Gateway, evolved packet data gateway), and then the ePDG forwards the registration request message to the WSDB.

S605. The database sends a registration response message to the access point.

Wherein, the registration response message includes user terminal identification, registration result, and available spectrum information in data format.

Specifically, after receiving the registration request message, WSDB can identify which user terminal is requesting registration according to the user terminal identification (ID) in the registration request message, and can identify the user terminal that is requesting registration according to the type information of the user terminal in the registration request message, fixed or handheld The identification and antenna height information are calculated to find the spectrum information available for the user terminal. Then, a registration response message including the user terminal identifier, registration result, and available spectrum information is sent to the access point.

For different implementations or different application scenarios, the process of "the database sends a registration response message to the access point" is also different. For example, in the control plane process, it includes but is not limited to the following Application scenarios.

For the following situations: 1. eNode B of LTE network; 2. AP of enterprise-level WIFI network; 3. When the WIFI access point in the converged network is a trusted AP, WSDB can directly send the above registration response message to Access point, no relay required during transmission.

However, when the WIFI access point in the converged network is an untrusted AP, as shown in Figure 7, the WSDB needs to send the registration response message to the ePDG first, and then the ePDG forwards the registration response message to the access point.

S606. The access point converts the registration response message from a data format to a signaling format.

Wherein, the registration response message includes a user terminal identifier in a signaling format, a registration result, and available spectrum information.

S607. The access point sends the registration response message to the user terminal.

The user terminal can know that the message is sent to itself according to the user terminal identifier in the registration response message, and can know whether it is successfully registered in WSDB according to the registration result in the registration response message. Available spectrum information uses spectrum CR technology to use unoccupied frequency spectrum resources and improve frequency utilization.

The embodiment of the present invention provides a method for registering in the database, by sending a registration request message to the access point, and converting the registration request message into a data format through the access point and sending it to the database, and then receiving the data sent by the database from the access point The registration response message can enable the user terminal to register in the database, so that the user terminal can obtain the right to use the frequency spectrum provided by the database, and then enable the user terminal to use the frequency spectrum resources, thereby improving the utilization rate of idle frequency spectrum.

Another method for registering in a database provided by another embodiment of the present invention, as shown in FIG. 8 , includes:

S801. The user terminal acquires the IP address of the database.

In the process of the data plane, after the user terminal completes the entire attachment (Attachment) process, and before the user terminal initiates a registration request to the WSDB, the user terminal can first obtain the address of the WSDB, for example, an IP address. The above data plane is the service plane, which refers to voice or data transmission.

Among them, the IP address of the WSDB can be obtained in the following two ways: 1. The user terminal receives the IP address of the WSDB sent by the access point; 2. The user terminal obtains the default IP address of the WSDB stored in itself. The IP address of the WSDB is generally set inside the user terminal by the manufacturer of the user terminal before leaving the factory.

After obtaining the IP address of the WSDB, the user terminal can initiate a registration request to the WSDB.

S802. The user terminal sends a registration request message to the access point (the specific process is completely the same as step S602 in the previous embodiment, and will not be described again).

S803. Send the registration request message to the database.

Specifically, on the data plane, the access point does not need to perform format conversion processing after receiving the registration request message, but performs transparent transmission.

For different implementations or different application scenarios, the process of "sending the registration request message to the database" is also different. For example, in the data plane process, it includes but is not limited to the following application scenarios .

For an AP of an enterprise-level WIFI network, after receiving the registration request message, the AP directly sends the registration request message to the WSDB, and no relay is required during the sending process.

For the eNode B of the LTE network, as shown in FIG. 9, after receiving the registration request message, the eNode B may first send the registration request message to the MME (Mobility Management Entity, mobile management entity), and then the MME Forwards the registration request message to WSDB.

Or, in another implementation manner, for the eNode B of the LTE network, after receiving the registration request message, the eNode B may first send the registration request message to a P-GW (Packet Gateway, packet gateway), Then the P-GW forwards the registration request message to the S-GW (Serving Gateway, serving gateway), and then the S-GW forwards the registration request message to the WSDB.

Or, there is another way of implementation. For the eNode B of the LTE network, after receiving the registration request message, the eNode B first sends the registration request message to the network management system, and then the network management system sends the registration request message to the network management system. Forward to WSDB.

When the WIFI access point in the converged network is a trusted AP, as shown in Figure 10, after receiving the registration request message, the trusted AP may first send the registration request message to the PDNGW (Public Data Network Gateway, public Data Gateway), and then the PDNGW forwards the registration request message to the WSDB.

When the WIFI access point in the converged network is an untrusted AP, as shown in Figure 11, after receiving the registration request message, the untrusted AP can first send the registration request message to the ePDG, and then the ePDG sends the registration request message to the ePDG. The registration request message is forwarded to the PDNGW, and then the PDNGW forwards the registration request message to the WSDB.

S804. The database sends a registration response message to the access point.

Wherein, the registration response message includes a user terminal identifier, a registration result, and available spectrum information.

Specifically, after receiving the registration request message, WSDB can identify which user terminal is requesting registration according to the user terminal identification (ID) in the registration request message, and can identify the user terminal according to the user terminal type information, fixed or handheld identification in the registration request message Calculate with the antenna height information to find the spectrum information available for the user terminal. Then, a registration response message including the user terminal identifier, registration result, and available spectrum information is sent to the access point.

For different implementations or different application scenarios, the process of "the database sends a registration response message to the access point" is also different. For example, in the data plane process, it includes but is not limited to the following Application scenarios.

For the AP of the enterprise-level WIFI network, WSDB can directly send the registration response message to the AP, and no relay is required during the sending process.

For the eNode B of the LTE network, as shown in FIG. 9 , the WSDB may first send the registration response message to the MME, and then the MME sends the message to the eNode B.

Or, in another implementation, for the eNode B of the LTE network, the WSDB can first send the registration response message to the S-GW, then the S-GW sends it to the P-GW, and then the P-GW sends it to the eNode B.

Or, in another implementation manner, the WSDB may first send the registration response message to the network management system, and then the network management system sends the message to the eNode B.

When the WIFI access point in the converged network is a trusted AP, as shown in Figure 10, the WSDB can first send the registration response message to the PDNGW, and then the PDNGW sends it to the trusted AP.

When the WIFI access point in the converged network is an untrusted AP, as shown in Figure 11, the WSDB can first send the registration response message to the ePDG, and then the ePDG forwards the registration response message to the PDNGW, and then the PDNGW sends the registration response message to the PDNGW. The response message is forwarded to the untrusted AP.

S805. The access point sends the registration response message to the user terminal.
