BACKGROUND OF THE INVENTION With the increase in the number of users of cellular mobile communication system operators and the increase in user demand for services, the scale of cellular networks is continuously expanding, and the number of base stations is increasing, and various types of cellular mobile communication systems are continuously deepened in cooperation with each other. Correspondingly, the management and maintenance of the neighbor relationship of cells in the cellular network becomes more and more cumbersome. Figure 1 is a system architecture diagram of a Universal Terrestrial Radio Access Network (UTRAN). As shown in Figure 1, the UTRAN mainly includes a Radio Network Controller (RNC) and a base station ( NodeB) Two basic network elements. The neighbor relationship between multiple cells under each NodeB will dynamically change with the needs of network planning optimization and the change of the wireless environment. In UTRAN, the correct neighborhood relationship in the small interval is very important for network performance. For example, the correct neighbor relationship can achieve optimal handover of mobile users or terminals (UE), ensure service continuity, and help the network achieve load balancing, capacity allocation, and energy saving. In the manual neighboring area, the network side notifies the configured neighboring cell relationship to the terminal (UE) through the system broadcast message or the proprietary control message, and the UE further stores and utilizes the received cell neighbor relationship. However, this well-configured neighborhood relationship may be outdated and does not truly reflect real-time neighbor relationships. For example, due to the intricacies of the wireless environment, especially in dense urban areas with high-rise buildings, it is difficult to determine exactly which neighboring areas should be configured in a certain area in the initial stage of network planning. Or, for example, a new cell or cell attribute change is added to the system, and the neighbor relationship of the cell is not updated in time; or the change of the environment or the omission of the network planner may cause the neighbor information to be updated in time. Therefore, the UE cannot switch to other cells in time, and the load of the cell is too high, the signal quality of the cell is deteriorated, the interference is severe, or the user drops the call. In order to be able to configure the neighbor relationship of the cell in time, an automatic Neighbor Relation (ANR) function is proposed in the UMTS system to add a 4p cell 歹'J table. The ANR function refers to the measurement of the physical layer information of the new cell by the UE and the uplink to the network side, and the network The side can learn the high-level information of a specific cell from the UE, and the network side completes the function of adding the neighbor cell list, and does not need to manually add the neighboring cell, and is automatically completed by the system. In actual applications, some UEs may support the ANR function, but some UEs may not support the ANR function. However, the inventors have found that in the prior art, the UE does not inform the network side whether it has the ANR capability. Therefore, the network side It is not known whether the UE has the ANR capability, and the dedicated control ANR measurement command sent by the network to some UEs cannot be executed, resulting in waste of over-the-air signaling. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a method and a transmission system for learning a terminal ANR capability, so as to at least solve the problem that the network side cannot know whether the UE has the ANR capability. According to an aspect of the present invention, a method for obtaining an automatic neighbor relationship capability of a terminal is provided, including: the terminal reporting, by the air interface signaling, whether the terminal has an ANR capability to the network side; the network side receiving the air interface signaling, and obtaining the Whether the terminal has ANR capability. The foregoing terminal reports whether the terminal has the ANR capability by using the air interface signaling to the network side.

As shown in FIG. 3, the method mainly includes the following steps: Step S302: The terminal reports to the network side whether the terminal has the ANR capability through the air interface signaling. In step S304, the network side receives the air interface signaling, and learns whether the terminal has the ANR capability. With the foregoing method provided by the embodiment of the present invention, the network side can learn whether the terminal has the ANR capability, so that the ANR measurement signaling can be sent to the terminal with the ANR capability. In the first preferred embodiment of the present disclosure, the terminal may indicate whether the terminal has the ANR capability on the network side by carrying an identifier indicating whether it has the ANR capability in the air interface signaling. Preferably, the identifier can occupy only 1 bit. For example, if the identifier is 0, it indicates that the terminal does not have the ANR capability. If the identifier has a value of 1, it indicates that the terminal has the ANR capability, and vice versa. After receiving the air interface signaling, the network side parses the identifier from the network, and according to the indication of the identifier, whether the terminal has the ANR capability. In practical applications, the ANR capability of the terminal can be embodied by at least one of the following ANR capabilities: Intra-frequency SI acquisition capability, inter-frequency SI acquisition capability, evolved universal terrestrial radio access network SI acquisition capability, global mobility The SI acquisition capability of the communication network. In the second preferred embodiment of the present invention, the terminal may carry multiple identifiers in the air interface signaling, which are respectively used to indicate whether the terminal has the foregoing sub-ANR capabilities. Preferably, each identifier may occupy 1 bit respectively, respectively indicating whether the terminal has a corresponding sub-ANR capability. Upon receiving the air interface signaling, the network side parses the identifier indicating whether the terminal has the foregoing sub-ANR capability, and learns the ANR capability of the terminal according to the indication of each identifier. In an actual application, the air interface signaling in the foregoing first preferred embodiment and the second preferred embodiment may extend an existing air interface message, and may also redefine a new air interface message dedicated to reporting the terminal ANR capability, for example, the foregoing. The air interface signaling can be implemented by extending the RRC connection completion message, that is, adding a field (or a cell) that indicates whether the terminal has the ANR capability or whether the terminal has the above-mentioned sub-ANR capability in the RRC connection completion message. Preferably, a field indicating whether the terminal has the ANR capability (as shown in Table 1 above) or whether the terminal has the above-mentioned sub-ANR capability fields may be added in the terminal radio access capability field (cell) of the RRC connection complete message ( As shown in Table 2 above). In a third preferred embodiment of the present invention, the terminal may modify the value of the access network version indication bit in the air interface signaling to a preset version (for example, version 10) when it has the ANR capability, and notify the On the network side, the preset terminal has the ANR capability, and the network side parses the value of the access network version indication bit from the air interface signaling, and determines whether the version indicated by the value is a preset version (for example, Version 10), if yes, determine that the terminal has ANR capability, otherwise, determine that the terminal does not have ANR capability. In the preferred embodiment, the terminal may not notify the network side that the default version of the default terminal has the ANR capability, but pre-parts with the network side to indicate that the terminal has the ANR-capable version. This can save air interface signaling. Embodiment 3 In the embodiment of the present invention, the UE reports to the network side whether it has the ANR capability through a dedicated control channel (Dedicated Control Channel, DCCH). 4 is a signaling flowchart of the UE reporting whether it has the ANR capability to the network side in the embodiment of the present invention. As shown in FIG. 4, the method mainly includes the following steps: Step 4: 401, the UE sends an RRC connection complete message through the DCCH (connection) Completely, the RRC connection completion message carries an ANR capability identifier, where the ANR capability identifier is used to indicate whether the UE has an ANR capability; specifically, the UE may add the terminal radio access capability cell of the RRC connection completion message. The ANR support cell shown in Table 1 carries the above ANR capability identifier through the cell. Step 402: The network side receives the RRC connection complete message, parses the ANR capability identifier from the network, and according to the indication of the ANR capability identifier, whether the UE has the ANR capability. With the above technical solution provided by the embodiment of the present invention, the UE may perform an ANR capability on the network side by extending the RRC connection message. Embodiment 4 In the embodiment of the present invention, the UE passes the Common Control Channel (CCCH) to the network side to determine whether it has the ANR capability. FIG. 5 is a signaling flowchart of the UE reporting whether it has the ANR capability to the network side according to the embodiment of the present invention. As shown in FIG. 5, the method mainly includes the following steps: Step 501: The UE sends an RRC connection request (connection request) message through the CCCH. The RRC connection request message carries the access network version indication bit and the value is the version 10, and the description of the default capability of the ANR capability to the version 10 is added to the semantic description cell in the RRC connection request message. Specifically, in the embodiment of the present invention, the access network version indication is located in the RRC connection Request message, and the access network version indication bit in the RRC connection request message is defined by using the definition as shown in Table 3, where the enumeration is added. The value is REL10 and adds a default capability that describes the ANR capability as version 10. Step 502: The network side receives the RRC connection request, parses the value of the access network version indication bit, and determines that the version indicated by the value is version 10, and determines that the UE has the ANR capability. With the embodiment of the present invention, the UE may indicate whether the UE has the ANR capability by using the access network version indication bit in the RRC connection request, thereby saving air signaling overhead. Embodiment 5 The embodiment of the present invention is similar to the foregoing Embodiment 3, except that the UE carries an identifier indicating whether it has the capability of each sub-ANR in the RRC connection complete message. In the embodiment of the present invention, the ANR capability is as follows.
