Background

The wireless communication network optimization is to reasonably adjust network parameters by adopting a technical means and an optimization tool, so that the maintenance work of the network quality is improved. Wireless communication network optimization is a very important link for network operators. Only through network optimization, the requirements of users can be fully met, the competitiveness of the network is provided, and the capability of the network is fully exerted. However, due to the complexity of the wireless environment and the scale of the system parameters, the optimization procedure of the wireless communication network is complex and needs to be continuously adjusted to achieve dynamic balance of the wireless communication network.

At present, the network optimization process is generally processed based on statistics and measurement data of the terminal and the base station. The data information that can be provided by a generic terminal is limited and therefore is usually performed using a special terminal that is capable of network quality testing. The common method is that the network optimization personnel hold a special terminal, carry on or walk, collect data according to a certain route, after the collected data are comprehensively analyzed in the background, output test reports and optimization suggestions. And the network optimization department analyzes the test report, evaluates the optimization suggestion, then issues an optimization instruction, and modifies the system parameters needing to be modified. And after the parameters are modified, field acquisition is carried out again, and after the network optimization is completed, the network optimization engineer can carry out field test again to verify whether the network problem is solved. If the network problem is not solved, the optimization process needs to be repeated again.

However, the existing network optimization has the following problems: (1) Because of the manual intervention link, a long time is needed from the measurement data to the parameter modification each time; (2) If the network problem is not solved, the field test needs to be reached for many times, which is time-consuming and labor-consuming; (3) The optimization effect after the parameters are modified cannot be observed in real time.

The present disclosure is described in detail below with reference to the attached drawings. In addition, the application scenarios described in the examples of the present disclosure are for more clearly illustrating the technical solutions of the present disclosure, and do not constitute a limitation on the technical solutions provided by the present disclosure.

The automatic wireless communication network optimization method can be suitable for WCDMA, LTE and NR technologies defined by 3GPP, and can also be suitable for other wireless communication technologies.

Fig. 1 is a schematic diagram illustrating an application scenario of an automated wireless communication network optimization method according to an example of the present disclosure. The automated wireless communication network optimization method according to the present disclosure can be applied to the communication system 1 shown in fig. 1. In some examples, as shown in fig. 1, a communication system 1 may include a terminal device 10 and an access network device 20. In some examples, the connection between the terminal device 10 and the access network device 20 may be established through a security authentication procedure (i.e., establishing a secure connection). In some examples, data interaction may occur between terminal device 10 and access network device 20.

In some examples, the terminal device 10 may include a hardware structure having a circuit function and/or a software module. I.e. the terminal device 10 may perform a network quality test. The software module with the road function may be, for example, a road test APP. For example, the terminal device 10 may be a special terminal (also referred to as a net-good terminal). The special terminal may be, for example, a smart phone with a drive test function, a notebook Computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and other electronic devices. The operating system of the terminal device 10 may include, but is not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a Black Berry operating system, a Windows Phone8 operating system, and the like. In some examples, the access network device 20 may be a base station. A base station (e.g., access point) can refer to a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals. The base station may be configured to interconvert received air frames and IP packets as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) network. The base station may also coordinate management of attributes for the air interface. For example, the Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved Node B (NodeB or eNB or e-NodeB) in LTE.

In other examples, the number of terminal devices 10 may be plural. A plurality of terminal devices 10 may establish connections and interact with data between access network devices 20.

In some examples, network optimization may be performed after a connection is established between one or more terminal devices 10 and the access network device 20. A specific procedure for performing network optimization between the terminal device 10 and the access network device 20 can be specifically described with reference to fig. 2. Fig. 2 is a flow chart illustrating an automated wireless communication network optimization method in accordance with an example of the present disclosure.

In some examples, as shown in fig. 2, an automated wireless communication network optimization method may include a terminal device establishing a secure connection with an access network device (step S111). In step S111, establishing the secure connection may include Radio Resource Control (RRC) connection establishment and authentication of the terminal device 10.

In step S111, the RRC connection setup includes an RRC connection request, an RRC connection setup confirmation, and an RRC connection setup completion. Specifically, the terminal device 10 may transmit a Radio Resource Control (RRC) connection request signal to the access network device 20. The radio resource control connection request signal may include a network priority ID and a special identifier. The access network device 20 identifies the special identifier to tag the network priority ID based on a Radio Resource Control (RRC) connection request signal. After marking the network priority ID, the access network device 20 transmits a Radio Resource Control (RRC) connection setup confirm signal to the terminal device 10. The terminal device 10 receives the radio resource control connection establishment acknowledgement signal transmitted by the access network device 20. The terminal device 10 transmits an RRC connection setup complete signal to the access network device 20 based on the RRC connection setup confirm signal.

In some examples, terminal device 10 may store a unique net good ID. The terminal device 10 may further store a first network priority Key (i.e., a first network priority Key) corresponding to the network priority ID. The first network optimization key may be used to encrypt signals transmitted by the terminal device 10.

In some examples, the RRC connection Request signal may refer to RRC Setup Request information (RRC Setup Request). In some examples, the RRC setup request Information may carry a special Information Element (IE). Specifically, a special IE (i.e., a special identifier) may be set in a Random Value (Random Value) of an Initial UE Identity (Initial UE-Identity) of the RRC establishment request message. For example, the special identifier may be a random value of 1 at all, for example.

In some examples, the RRC connection setup is completed after the terminal device 10 transmits the RRC connection setup complete signal. In some examples, after the RRC connection establishment is completed, the terminal device 10 may perform a network quality test through the service establishment, and then the terminal device 10 may send a NAS message, where if the service establishment is not required, the length of the NAS message is 0. In some examples, RRC connection establishment may enable configuration of time domain resources, frequency domain resources, and the like. The time domain resources may include, for example, frames, symbols, slots, and the like. The frequency domain resources may include, for example, bandwidth, resource blocks, and the like.

In other examples, the initialization may be performed before the terminal device 10 sends the RRC connection request signal to the access network device 20. The access network device 20 may perform initialization before receiving the RRC connection request signal, and after the initialization, the access network device 20 may enter a state in which it is ready to receive the RRC connection request signal of the terminal device 10.

In some examples, after completing the RRC connection setup in step S111, the terminal device 10 enters an authentication phase. I.e. to authenticate the terminal device 10. The authentication and authorization process may be implemented by an uplink direct Transfer (UL Information Transfer) or a downlink direct Transfer (DL Information Transfer). The uplink direct transfer message or the downlink direct transfer message is a direct transfer message based on an RRC protocol.

In some examples, the terminal device 10 may transmit the upstream direct transfer information based on a network optimization protocol. The upstream direct transfer information may include registration request information having a network priority ID. In other words, the terminal device 10 may initiate a registration request to the access network device 20.

In some examples, the network optimization protocol may be located in an extension information element of the RRC protocol. The network optimization protocol can be defined by Abstract Syntax Notation (asn.1), and can be encoded and decoded by the same method as the RRC protocol. The extension unit of the bearing network optimization protocol comprises a registration request field, an authentication request field and an authentication response field. Thereby, the authentication of the terminal device 10 can be completed based on the field in the extension unit of the bearer network optimization protocol. The registration request field in the extension unit in the uplink direct transfer information when the registration request is initiated may include a network priority ID.

In some examples, the terminal device 10 and the access network device 20 may communicate the network optimization protocol through an uplink direct Transfer (UL Information Transfer) or a downlink direct Transfer (DL Information Transfer). In some examples, since the network optimization protocol is carried in an extension information unit of the RRC protocol, the uplink direct transfer message or the downlink direct transfer message is a direct transfer message based on the RRC protocol. Therefore, the network optimization protocol can be located in an expansion unit in the uplink direct transmission information or the downlink direct transmission information. In some examples, the RRC message for transferring the network optimization protocol may not include a NAS (Non-Access Stratum) message. Late non-critical extensions (lateroncriticalextension) or non-critical extensions (nonCriticalExtension) in the IEs in the RRC message may be used to carry the network optimization protocol. And the interaction of the network optimization protocol is realized in the process of establishing the secure connection in the step S111.

In some examples, access network device 20 may send the downstream direct transfer information based on the registration request information and the network optimization protocol. In particular, the access network device 20 may be provided with a specific network priority ID and a corresponding second network priority key. The access network device 20 may store a sequence number. The access network device 20 may generate a random value. The second network optimization key may be used to decrypt the upstream direct transmission information sent by the terminal device 10. After the access network device 20 obtains the registration request information, the access network device 20 may generate authentication request information based on the second network optimization key, the sequence number, and the random value to initiate an authentication request. The authentication request information may be located in the authentication request field. And generating downlink direct transmission information based on the authentication request information.

In some examples, the terminal device 10 may perform the authentication response based on the received downstream direct transfer information. Specifically, the terminal device 10 may generate a random value. The terminal device 10 may decrypt the downstream direct transmission information by using the first network optimization key to obtain the target serial number. The terminal device 10 may generate authentication response information based on the first network optimization key, the target serial number, and the random value to perform an authentication response. The authentication response information may be located in the authentication response field. The access network device 20 may receive the uplink direct transmission information including the authentication response information and determine that the terminal device is a network-preferred terminal.

In some examples, as shown in fig. 2, an automated wireless communication network optimization method may include a terminal device obtaining test data (step S112). In step S112, the terminal device 10 performs a network quality test to obtain test data. In some examples, the primary parameters for network quality testing may include quality of service parameters and radio channel quality. The service quality parameters may include throughput, delay, and packet loss rate. The wireless channel quality may include signal strength and signal-to-noise ratio. In other words, network quality tests can be performed by measuring and calculating throughput, delay, packet loss rate, signal strength and signal-to-noise ratio. That is, the test data may include at least one of throughput, delay, packet loss rate, signal strength, and signal-to-noise ratio.

In some examples, terminal device 10 may perform network quality testing in real-time. In some examples, the terminal device 10 may send a NAS message for the service request to the access network device 20 and receive a service feedback signal sent by the access network device 20, and the terminal device 10 may perform a network quality test based on the service feedback signal to obtain the test data.

In some examples, as shown in fig. 2, an automated wireless communication network optimization method may include uploading test data to an access network device over an air interface (step S113). In step S113, the air interface may be referred to as an air interface. The test data may be sent to the access network device 20 over the air. Information over the air interface may be referred to as air interface information.

In some examples, as shown in fig. 2, an automated wireless communication network optimization method may include an access network device obtaining test evaluation results based on test data (step S114). In step S114, the test evaluation result may be at least one parameter value obtained based on the above-mentioned main parameters for performing the network quality test.

In some examples, as shown in fig. 2, the automated wireless communication network optimization method may include testing whether the evaluation result meets a preset requirement (step S115). In step S115, the test evaluation result may be compared with the preset requirement, and if the test evaluation result does not meet the preset requirement, the network quality is poor. The preset requirement may be a threshold value corresponding to a test evaluation result in the communication system.

In some examples, as shown in fig. 2, an automated wireless communication network optimization method may include making network parameter modifications (step S116). In step S116, if the test evaluation result does not meet the preset requirement, the access network device 20 may calculate the network parameter to be modified and modify the network parameter to implement network optimization. In some examples, access network device 20 may calculate the network parameters that need to be modified in real-time and perform the network parameter modifications in real-time. Therefore, the network optimization efficiency can be improved, and the network effect after the network parameters are modified can be observed in real time. In some examples, the modified network parameters may be calculated in a gradient manner.

In some examples, the modified network parameters may include at least one of a total transmit power, a reference signal power, a power ratio of different channels, a measurement control parameter, a cell bandwidth, and related RRM parameters. In some examples, the total transmit power may be a total downlink transmit power or a total uplink transmit power. The power ratio between the different channels may be, for example, the power ratio of the control channel to the data channel. The data channel may be referred to as a shared channel. From the physical layer perspective, the control channel and the data (shared) channel may be divided into multiple physical channels. The uplink and downlink main physical channels may include six. Specifically, the Physical channels may include a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Channel (PDSCH), a Physical Hybrid automatic repeat Indicator Channel (PHICH), a Physical Control Format Indicator Channel (PCFICH), a Physical Uplink Control Channel (PUCCH), and a Physical Uplink Shared Channel (PUSCH). Thus, the power ratio of the different channels may be the power ratio between the at least two physical channels. The reference signal may include a downlink reference signal or an uplink reference signal.

In some examples, as shown in fig. 2, an automated wireless communication network optimization method may include generating a feedback signal to transmit to a terminal device (step S117). In step S117, the feedback signal may be used to instruct the terminal device 10 to perform the network quality test again to retrieve the test data.

In some examples, as shown in fig. 2, an automated wireless communication network optimization method may include sending an end optimization instruction to a terminal device (step S118). In step S118, if the test evaluation result meets the preset requirement, the access network device 20 may send an end optimization instruction to the terminal device 10 to end the automated network optimization.

In some examples, an automated wireless communication network optimization method may include a terminal device re-conducting a network quality test based on a received feedback signal to retrieve test data. That is, after the access network device 20 generates the feedback signal and sends the feedback signal to the terminal device 10, the step S112 is returned to, and the terminal device 10 may perform the network quality test again to obtain the test data again.

In some examples, the automated wireless communication network optimization method may include that the access network device completes the automated network optimization (i.e., stops the loop) if the test evaluation result obtained by the access network device based on the re-received test data meets the preset requirement, otherwise the terminal device 10 may re-perform the network quality test based on the feedback signal generated by the access network device 20.

In the disclosure, by the above-mentioned automated wireless communication network optimization method, time intervals from measurement data to parameter modification can be reduced by manual intervention links such as a parameter optimization suggestion link and an optimization instruction issuing, a network effect after parameter modification is observed in real time, and multiple times of on-site tests are avoided, so that network optimization efficiency can be improved.

In some examples, after completing the automated network optimization, access network device 20 may report the modified network parameters to a server in the background.

In some examples, the number of terminal devices 10 may be plural.
