Definitions
- the present invention relates to radio communication technology, and more particularly to a mobile station, a radio access network apparatus, and a neighboring cell information notification method.
- a mobile station monitors a cell. For this reason, the neighboring cell information is notified to the mobile station as broadcast information or information to be transmitted individually (see, for example, Non-Patent Document 1).
- O Neighboring cell information is used in each cell. Includes primary CPICH (Common Pilot Channel) scrambling code (9b its) and timing offset between cells!
- Non-Patent Document 1 3GPP TS25.331 8.6.7
- Non-Patent Document 2 3GPP TS25.814 7.1.1.5
- An object of the present invention is to provide a radio access network apparatus and a neighboring cell information notification method that enable switching of a mobile station operation depending on whether or not handover is performed within the same base station.
- a radio access network apparatus of the present invention is a radio access network apparatus in a mobile communication system including a mobile station and a radio access network apparatus, and indicates a first cell identifier.
- First cell identifier selecting means for selecting an identifier, second cell identifier selecting means for selecting an identifier indicating a second cell identifier, the first cell identifier and the second cell identifier are stored, and neighboring cell information is created.
- One of the features is that it includes peripheral cell information generating means.
- the mobile station that has received neighboring cell information can determine the hierarchical structure of the cell.
- the mobile station operation is switched depending on the power between cells in the same base station, and handover within the same base station is controlled at a high speed in a layer lower than RRC.
- the neighboring cell information reporting method of the present invention is a neighboring cell information broadcasting method in a mobile communication system composed of a mobile station and a radio access network device, and selects an identifier indicating a first cell identifier.
- One of the features is that it includes a cell information generation step.
- the mobile station that has received the neighboring cell information can determine the hierarchical structure of the cell.
- the mobile station that has received the neighboring cell information understands the hierarchical structure of the cell from the first cell identifier and the second cell identifier, and when the first cell identifier is different, It is possible to switch the mobile station operation.
- FIG. 1 is a block diagram showing a mobile communication system according to an embodiment of the present invention.
- FIG. 2 is a block diagram showing a radio access network apparatus according to an embodiment of the present invention.
- FIG. 3 is a configuration diagram of a first cell identifier and a second cell identifier according to an embodiment of the present invention.

- the mobile station 100 and the radio access network device 200 can perform radio communication with each other through at least a shared data channel.
- the radio access network apparatus 200 also functions as a radio base station and directly performs radio communication with the mobile station 100.
- the radio access network device 200 does not have the function of a radio base station, and a plurality of radio base stations controlled by the radio access network device 200 are prepared. Communication with the mobile station 100 may be performed through the network.
- the wireless access network device 200 includes a data transmission / reception unit 210 as transmission / reception means, A peripheral cell information generation unit 220 connected to the data transmission / reception unit 210, a first cell identifier selection unit 230, and a second cell identifier selection unit 240 connected to the peripheral cell information generation unit 220 are provided.
- the radio access network apparatus 200 is configured with a radio base station and a radio control apparatus, all or part of each function may be distributed to the radio base stations.
- Data transmission / reception section 210 receives uplink signals and other uplink signals transmitted from mobile station 100.
- the data transmitter / receiver 210 transmits peripheral cell information and other downlink signals to be transmitted to the mobile station 100 and other mobile stations.
- First cell identifier selection section 230 and second cell identifier selection section 240 each select a cell identifier.
- the cell configuration may be a hierarchical structure as shown in FIG. 3.
- the parent tree portion may be the first cell identifier and the child tree (branch) portion may be the second cell identifier.
- the parent tree portion may be a radio access network device, and an identifier unique to the radio access network device may be selected as the first cell identifier (cells belonging to a certain radio access network 1 are distinguished by a to e). The cells belonging to different radio access networks 2 are distinguished by a to e.) O
- the scramble code unique to the radio access network device may be used as the first cell identifier.
- the child tree (branch) portion may be a cell in the same radio access network apparatus, and a cell-specific identifier in the radio access network apparatus may be selected as the second cell identifier.
- a scramble code unique to a cell in the radio access network apparatus may be used as the second cell identifier.
- the parent tree portion may be a frequency in the radio access network device, and an identifier specific to the frequency of the radio access network device may be selected as the first cell identifier.
- the child tree (branch) portion is a cell within the same radio access network apparatus and within the same frequency, and a cell-specific identifier within the radio access network apparatus and within the same frequency is used as a second cell identifier. You may choose.
- the second cell identifier may be a combination of the second cell identifier and the accompanying short cell identifier as the second cell identifier. If it is necessary to put a cell identifier in the uplink signal transmitted by the mobile station in order to shorten the length of the uplink signal, the short cell identifier may be notified in this way.
- the radio access network device 200 may be realized by a control device 201 and a radio base station device 202, for example, as shown in FIG.
- the radio control apparatus 201 and the radio base station 202 are separately prepared for the case where the radio access network apparatus 200 has the function of the radio control apparatus 201 and the function of the radio base station 202. May be. However, from the viewpoint of shortening the delay time associated with data transmission, it is desirable to prepare them in the same device.
- the mobile station can determine the hierarchical structure of the cell, the mobile station operation related to the handover can be appropriately switched based on the difference in the first cell identifier.
