Fig. 1 is a schematic view illustrating an application scenario of an automated network optimization method according to an example of the present disclosure. The NAS-based automated network optimization method according to the present disclosure may be applied to the communication system 1 shown in fig. 1. In some examples, as shown in fig. 1, communication system 1 may include a terminal device 10 and a processing system 20. Processing system 20 may include a core network device 21, a network management system 22, and an access network device 23. In some examples, a connection may be established between the terminal device 10 and the core network device 21 of the processing system 20. In some examples, data interactions may be performed between terminal device 10 and processing system 20.

In some examples, terminal device 10 may include hardware structures and/or software modules with drive test functionality. The software module with the drive test function may be, for example, a drive test APP. For example, the terminal device 10 may be a special terminal (also referred to as a network optimization terminal). The special terminal can be various electronic devices such as a smart phone with a drive test function, a notebook computer, a personal computer (Personal Computer, PC), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet device (Mobile Internet Device, MID) and the like. 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 core network device 21 may be a core network control node. The core network control node performs data interaction with the terminal device 10. The core network device 21 may be a switch. In some examples, the network management system 22 (Network Management System, NMS) may interact data with the core network device 21. Network management system 22 may interact with access network device 23.

In some examples, access network device 23 may be a base station. A base station (e.g., access point) may 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 inter-convert the received air frames with 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 attribute management for the air interface. For example, the base station may be a base station (BTS, base Transceiver Station) in GSM or CDMA, a base station (NodeB) in WCDMA, or an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in LTE.

In other examples, the number of terminal devices 10 may be multiple. Connections may be established and data interactions may take place between a plurality of terminal devices 10 and the processing system 20. In some examples, network optimization may occur after a connection is established between one or more terminal devices 10 and processing system 20. The specific steps of network optimization between a terminal device 10 and a processing system 20 may be described in detail in connection with fig. 2. The NAS-based automated network optimization method related to the present disclosure may be simply referred to as an automated network optimization method. Fig. 2 is a flow chart illustrating an automated network optimization method in accordance with examples of the present disclosure.

In some examples, as shown in fig. 2, the automated network optimization method may include the terminal device initiating a registration request (step S111). In step S111, the terminal device 10 may send NAS request information to the core network device 21 in the processing system 20 to initiate a registration request. The NAS request information may include a network optimization function registration request. The core network device 21 confirms that the terminal device 10 has an automatic network optimization capability based on the network optimization function registration request in the NAS request information, supporting an automatic network optimization protocol. In other examples, the terminal device 10 may be subjected to an initialization process before performing step S111.

In some examples, as shown in fig. 2, the automated network optimization method may include the core network device acknowledging the registration request (step S112). In step S112, the core network device 21 may parse the automated network optimization protocol based on the received NAS request information and send NAS acknowledgement information to the terminal device 10 to acknowledge the registration request. The NAS acknowledgement information includes network optimization function registration acknowledgements and user IDs. The user ID may be a unique user ID assigned to the terminal device 10 by the core network device 21.

In some examples, as shown in fig. 2, the automated network optimization method may include the terminal device transmitting a heartbeat signal (step S113). In step S113, the terminal device 10 transmits a heartbeat signal to the core network device 21 every preset time. That is, the terminal device 10 periodically transmits the heartbeat signal. In some examples, as shown in fig. 2, the automated network optimization method may include the core network device sending a heartbeat acknowledgment signal (step S114). In step S114, the core network device 21 transmits a heartbeat acknowledgment signal to the terminal device 10 based on the received heartbeat signal to ensure that the core network device 21 and the terminal device 10 are connected normally.

In some examples, as shown in fig. 2, the automated network optimization method may include the terminal device sending a network optimization request (step S115). In step S115, the terminal device 10 generates NAS optimization request information based on the automated network optimization protocol to make a network optimization request. The NAS optimization request information may include a network optimization parameter set and a user ID. The terminal device 10 may perform mobile network testing and network quality assessment prior to making the network optimization request. In some examples, the primary parameters for mobile network testing and network quality assessment may include quality of service parameters and wireless channel quality. The quality of service parameters may include throughput, delay, and packet loss rate, among others. The wireless channel quality may include signal strength and signal-to-noise ratio. In other words, mobile network testing and network quality assessment may be performed by measuring and calculating throughput, latency, packet loss rate, signal strength, and signal-to-noise ratio. Therefore, mobile network testing and network quality evaluation can be performed on a plurality of parameters, and accuracy of testing evaluation results is improved.

In some examples, the automated network optimization protocol may be carried in additional information (Additional information) carried by the initial NAS signaling to obtain the target NAS signaling. I.e. the target NAS signaling may comprise an automated network optimization protocol for initial NAS signaling and additional information bearers. The initial NAS signaling may be obtained by NAS protocol definitions in 3 GPP. The initial NAS signaling is NAS signaling that is used for uplink and downlink. The target NAS signaling of the present disclosure may compromise maintaining the compatibility and integrity of NAS signaling. The additional information carrying the automated network optimization protocol may include a first byte of the additional information field, a protocol version number, a user ID, a protocol message type, a message length, a message sequence number, and a network optimization parameter set. Since the NAS optimization request information in the present disclosure pertains to target NAS signaling, in this case, the NAS optimization request information may further include a first byte of the additional information field, a protocol version number, a protocol message type, a message length, and a message sequence number. The unit of the message length may be bytes. Thereby, the message format of the data packets sent by the terminal device or the core network device can be further defined based on the automated network optimization protocol. In some examples, the additional information value (Additional information value) character paragraph in the additional information may be carried by the automated network optimization protocol.

In step S115, a mobile network test and a network quality evaluation are performed to obtain a test evaluation result. And comparing the test evaluation result with a preset requirement. If the test evaluation result does not meet the preset requirement, the network quality is poor. The test evaluation result may be at least one value obtained based on the main parameters for performing mobile network test and network quality evaluation, and the preset requirement may be a threshold value corresponding to the test evaluation result in the communication system. In some examples, the terminal device 10 may transmit a service request signal to the core network device 21 and receive a service feedback signal transmitted by the core network device 21, and the terminal device 10 may perform mobile network testing and network quality evaluation based on the service feedback signal to obtain a test evaluation result.

In step S115, if the network quality is poor, the terminal device 10 generates a network optimization parameter set. The network optimization parameter set may include, but is not limited to, an optimized total transmit power, a reference signal power, power ratios of different channels, measurement control parameters, cell bandwidths, and related RRM parameters. Therefore, the access network equipment can be convenient to optimize the total transmitting power, the power ratio of different channels and the measurement control parameters based on the network optimization parameter set. 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 a plurality of physical channels. The primary physical channels of the uplink and downlink may include six. Specifically, the physical channels may include a physical downlink control channel (Physical Downlink Control Channel, PDCCH), a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), a physical hybrid automatic repeat request indicator channel (Physical Hybrid ARQ Indicator Channel, PHICH), a physical control format indicator channel (Physical Control Format Indication Channel, PCFICH), a physical uplink control channel (Physical Uplink Control Channel, PUCCH), and a physical uplink shared channel (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 signals may include downlink reference signals or uplink reference signals.

In some examples, as shown in fig. 2, the automated network optimization method may include the core network device transmitting a network optimization request (step S116). In step S116, the core network device 21 may obtain a network optimization parameter set based on the received NAS optimization request information, and transmit a first optimization request signal including the network optimization parameter set to the network management system 22 through a Simple Network Management Protocol (SNMP).

In some examples, as shown in fig. 2, the automated network optimization method may include the network management system transmitting a network optimization request (step S117). In step S117, the network management system 22 may receive the first optimization request signal and transmit a second optimization request signal to the access network device 23 through a Simple Network Management Protocol (SNMP). Specifically, the network management system 22 may obtain the network optimization parameter set based on the received first optimization request signal. Network management system 22 may validate the network optimization parameter set to obtain the target network optimization parameter set. Because the network management system 22 can test, configure, analyze, etc. the network resources, the network optimization parameter set can be determined by analyzing, checking or modifying the network optimization parameter set, and the network optimization parameter set after analysis, checking or modifying is the target network optimization parameter set. The network management system 22 may generate a second optimization request signal based on the target network optimization parameter set and a Simple Network Management Protocol (SNMP).

In some examples, as shown in fig. 2, the automated network optimization method may include the access network device sending a network optimization acknowledgement (step S118). Specifically, in step S118, the access network device 23 may receive the second optimization request signal. The access network device 23 may perform network optimization by adjusting the optimized network parameters based on the network optimization parameter set in the second optimization request signal. The access network device 23 generates an optimization acknowledgement order when performing network optimization and transmits a first optimization acknowledgement signal comprising the optimization acknowledgement order to the network management system 22 via a simple network management protocol.

Adjusting the optimized network parameters when the access network device 23 performs network optimization in step S118 may include, but is not limited to, total transmit power of the access network device 23, reference signal power, control channel power, data channel power, power ratios of different channels, measurement control parameters, cell bandwidth, and related RRM parameters.
