Neighbor information transmission method and information transmission method

The present invention relates to the field of communications, and in particular, to a neighboring area information transmitting method and an information transmitting method. BACKGROUND In a wireless communication system, a base station is a device that provides services for a terminal, and a base station communicates with a terminal through an uplink/downlink. The downlink (forward) refers to the direction from the base station to the terminal, and the uplink (reverse) is Refers to the direction of the terminal to the base station. When the base station and the terminal perform data transmission, multiple terminals can simultaneously transmit data to the base station through the uplink, or can simultaneously receive data from the base station through the downlink. The quality of wireless coverage in mobile networks can impact users' enjoyment of high-speed data, voice services, and video services. In order to achieve seamless coverage of wireless networks, it is necessary to solve the coverage problems in indoor and hotspot areas. At present, the following two solutions are mainly used to achieve seamless coverage of wireless networks: One is the Macro Base Station (Macro Base Station) The number and density of Macro BS or Macro Cell); the other is to install a home base station (Femto Base Station, called Femto Cell or Femto BS) (also known as personal base station), stand alone: base station (Pico Base Station) A small base station with a low transmission power, such as a Pico Cell or a Pico BS. Since the traditional macro base station is close to the capacity limit used by the frequency spectrum, even if the macro base station with larger power is added, the indoor coverage problem will not be improved, but more radiation pollution will be caused, but Femto BS and Pico are used. Small base stations such as BS can not only solve the coverage problem of indoor and hotspots well, but also increase the system capacity more greatly in the existing frequency resources. A large number of Femto BSs, Pico BSs, and other small base stations with low transmit power may exist in the coverage area of a macro base station. To ensure that the terminal switches between the macro base station and the small base station, and that the terminal switches between the small base stations, The macro base station usually needs to broadcast a long neighbor list information (the neighbor list information includes neighboring macro base stations, and related system information of small base stations in the coverage area of the macro base station, etc.), and each terminal receives the neighbor list information. A base station in which the service can be served is selected as the base station to be scanned and/or the target base station. It can be seen that, in the foregoing solution, the base station sends the neighboring cell column to all terminals through the system broadcast.

Table 2. Neighbor list messages sent by the base station

After the base station sends the neighbor list information to the terminal, the base station sends the neighbor list message to a terminal or all terminals or terminal groups. If only the terminal is sent to one terminal, the base station can unicast. The method of transmitting the neighbor list message to the terminal; if sent to all terminals, the base station may send the neighbor list message to all terminals by means of broadcast; if sent to the terminal group, the base station may adopt a multicast manner The neighbor list message is sent to the corresponding terminal group. After receiving the neighboring cell list message from the base station, the terminal obtains the parameter information in the neighboring cell list message, for example, the terminal may obtain the related base station according to the base station type information in the neighboring cell list information. Type (for example, macro base station, Femto BS, Pico BS), the terminal can also perform neighbor list information The analysis obtains the BCH channel (the position of Bro) of the associated neighboring Femto BS. The main purpose of the base station for obtaining the service for the terminal is to select the base station to be scanned and/or the target handover base station among the base stations. Specifically, the base station can select the reference base station set according to the base station type information and the base station identifier. Any one of the base stations (ie, the first reference base station described above) serves as the base station to be scanned, and the terminal may also select any one of the reference base station sets according to the base station type information and/or the base station identifier (ie, The first reference base station described herein is a target handover base station, where the base station to be scanned and the target handover base station may be the same or different. In a specific implementation process in which the terminal selects the base station to be scanned and/or the target handover base station, the terminal preferentially selects the base station whose base station type information is indicated as the Femto base station as the base station to be scanned and/or the target handover base station, and preferably selects according to the base station status information. The base station status information indicates a Femto base station that is a closed subscriber group as a base station to be scanned and/or a target handover base station. For example, if the neighbor list information includes the parameter information of the macro base station and the parameter information of the Femto BS, the terminal preferentially selects the Femto BS as the base station to be scanned, and after selecting the Femto BS as the base station to be scanned, the terminal preferably selects the Close. The Femto BS of the state is used as a base station to be scanned. If the neighbor list information includes the description information of the neighboring macro base station of the terminal and the description information of the neighboring Femto BS, the terminal first selects the Femto BS as the handover target base station, and selects the Femto BS as the handover target base station, The terminal preferentially selects the Femto BS in the Close state as the handover target base station. In addition, if the number of base stations included in the neighbor list message is greater than the number of the maximum neighbor base stations supported by the terminal, the terminal may select and retain parameter information of the part of the base station according to the base station type information, where the predetermined The sequence may be: a Femto base station, another base station, and the other base stations include a Pico base station and/or a macro base station; for other base stations, the terminal selects and stores parameter information of the corresponding base station according to the order of other base stations in the neighbor list message. For example, if the number of neighboring base stations included in the neighbor list information is greater than the maximum number of neighbors that the terminal can support, the terminal should reserve multiple neighboring base stations of the maximum number of neighbors that it can support. Relevant information, and preferentially save the relevant information of the Femto BS, more preferably, the terminal preferentially retains the information of the Femto BS in the Close state. If the number of base stations of the Femto base station included in the neighbor list message is smaller than the number of base stations supported by the terminal, the terminal selects and saves the parameter information of the corresponding base station according to the order of other base stations in the neighbor list message, until The number of base stations saved by the terminal reaches the maximum number of neighboring base stations supported by the terminal. In addition, the terminal may determine the broadcast channel location of the corresponding base station according to the sending location information of the broadcast channel of the base station in the parameter information; the terminal may also be based on the synchronization channel of the base station in the parameter information. The transmission location information determines the synchronization channel location of the corresponding base station. The technical solution provided by the embodiment of the present invention enables the base station to send related information of each base station that can provide services to the terminal to the terminal, so that the terminal can select the base station to be scanned and the target handover base station among the base stations provided by the base station, and solve the problem.
