This application is a continuation of International Patent Application No. PCT/CN2011/075801, filed on Jun. 16, 2011, which is hereby incorporated by reference in its entirety.


TECHNICAL FIELD
The present invention relates to mobile communication technologies and, in particular, to a transmitting and a receiving method and a device.
BACKGROUND
Characteristics of a self-organization network (Self-Organization Network, SON) include an automatic neighbor relation (Automatic Neighbor Relation, ANR) function. According to the ANR function, automatic discovery of unknown cells and switching problem between cells with conflict physical cell identity (Physical Cell Identity, PCI) are realized, mainly through reporting, by a user equipment, (User Equipment, UE) a cell global identity (Cell Global Identity, CGI) after reading a system message of a neighbor cell. Reporting an eNB identity (eNB ID) by the UE is required in both an ANR switching and solving the PCI conflict.
Taking the ANR switching in a long term evolution (Long Term Evolution, LTE) system as an example, the cell global identity is an evolved universal terrestrial radio access network cell global identity (Evolved Universal Terrestrial Radio Access Network CGI, ECGI). In this case, the UE reports the ECGI to the network side, where the ECGI includes the eNB ID.
Currently, the LTE defines base stations (eNodeBs, eNBs) in two types: macro (macro) base station and home (Home) base station, where, an eNB ID of a macro base station occupies first 20 bits (bit) of an ECGI while last 8 bits of the ECGI serve as cell ID (Cell ID); an eNB ID of a home base station occupies integral 28 bits of an ECGI.
In current solutions, a base station controlling a neighbor cell which has been newly discovered during the ANR is treated as a macro base station as default. However, it is possible that the base station controlling a newly discovered neighbor cell is a home base station. In this case, if such base station is treated as the macro base station, an error regarding the identification of the eNB ID occurs undoubtedly. Therefore, this manner can not ensure that the base station type is identified accurately or the base station identification is acquired accurately.

DESCRIPTION OF EMBODIMENTS
In order to make the objectives, technical solutions, and advantages of embodiments of the present invention more clearly, the technical solutions in embodiments of the present invention are hereinafter described clearly and completely with reference to the accompanying drawings in embodiments of the present invention. Obviously, the described embodiments are only a part of embodiments of the present invention, rather than all embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on embodiments of the present invention without any creative efforts shall fall within the protection scope of the present invention.
FIG. 1 is a schematic flow chart of a transmitting method according to an embodiment of the present invention. The transmitting method includes:
Step 11: determining, by a terminal, a base station type of a base station controlling a neighboring cell of a serving cell;
Where, the neighboring cell of the serving cell may be a neighboring cell of the serving cell discovered during an automatic neighbor relation detecting. For example, in a SON network, a UE may detect other neighboring cells excluded from the neighboring cell list through the ANR process, that is, the neighboring cell automatically discovered is detected. The UE may report the base station identity of the neighboring cell automatically discovered to a network side. At this time, the above neighboring cell of the serving cell may be the neighboring cell automatically discovered in particular.
The base station type corresponding to the neighboring cell of the serving cell may be a macro base station, or may be a home base station. It can be determined that whether the neighboring cell of the serving cell is a macro base station or a home base station through an automatic neighbor relation detection.
Step 12: transmitting, by the terminal, information indicating the base station type to a network device, so that the network device determines the base station type according to the information indicating the base station type.
For example, the information indicating the base station type is a PCI, and the terminal transmits the PCI of the neighboring cell to the network device; where, the PCI is allocated to the neighboring cell by the terminal, and belongs to a PCI group corresponding to the base station type of the base station controlling the neighboring cell, and does not belong to at least one PCI group not corresponding to the base station type of the base station controlling the neighbor cell.
For another example, the information indicating the base station type is a base station type carried in a cell global identity, and the terminal transmits a cell global identity of the neighboring cell to the network device, where the cell global identity carries the base station type of the neighboring cell.
According to this embodiment of the present invention, the terminal transmits information indicating the base station type to the network device, therefore, the network side is enabled to determine the base station type and, thus, the accurate recognization of the base station type is realized.
FIG. 2 is a schematic flow chart of a transmitting method according to another embodiment of the present invention. The method includes:
Step 21: determining, by a terminal, a base station type of a base station controlling a neighboring cell of a serving cell;
For example, reference may be made to the description about Step 11.
Step 22: selecting, by the terminal, a PCI from the PCI group corresponding to the base station type of the base station controlling the neighboring cell, and allocating the PCI to the neighboring cell; where, the PCI corresponding to the neighboring cell belongs to the PCI group corresponding to the base station type of the base station controlling the neighboring cell, and does not belong to at least one PCI group not corresponding to the base station type of the base station controlling the neighboring cell.
For example, the base station type of the base station controlling the neighboring cell is a macro base station, and at least one base station type does not correspond to the base station controlling the neighboring cell is a home base station; or, the base station type of the base station controlling the neighboring cell is a home base station, and at least one base station type does not correspond to the base station controlling the neighboring cell is a macro base station.
Specifically, when the base station type of the base station controlling the neighboring cell is the macro base station, the PCI is any value from 0 to 412; when the base station type of the base station controlling the neighboring cell is the home base station, the PCI is any value from 413 to 511.
Specifically, in this embodiment, all the PCIs which are available for allocation may be divided into at least two groups, each group corresponds to different base station types, and then, a PCI in a PCI group corresponding to the base station type of the base station controlling the neighboring cell of the serving cell is allocated to the neighboring cell of the serving cell.
For example, the number of PCIs which are available to be allocated is 512, and the number of PCI groups is two, where one PCI group corresponds to the macro base station and the other PCI group corresponds to the home base station and, where, the PCI in the PCI group corresponding to the macro base station ranges from 0 to 412, and the PCI in the PCI group corresponding to the home base station ranges from 413 to 511. Thereby, if the base station type of the base station controlling the neighboring cell is a macro base station, the PCI allocated to the neighboring cell is within the range of 0 ̃412; if the base station type of the base station controlling the neighboring cell is a home base station, the PCI allocated to the neighboring cell is within the range of 413 ̃511.
It should be understand that the UE may obtain the base station type of the base station controlling the neighboring cell through the ANR process.
Additionally, the UE may allocate different PCIs to different neighboring cells. For example, the base station type of both a first neighboring cell and a second neighboring cell is a macro base station, the PCI allocated to the first neighboring cell may be 0, and the PCI allocated to the second neighboring cell may be 1, so as to ensure the PCIs of each cell do not conflict.
Furthermore, the allocated PCI may be represented by a primary synchronization sequence and a secondary synchronization sequence. For example, the secondary synchronization sequence has 168 groups, where each group includes 3 cells, and each cell is represented by the primary synchronization sequence. Certainly, this example may represent 168×3=504 PCIs, besides, the primary synchronization sequence and/or the secondary synchronization sequence may be extended to represent the foregoing 512 PCIs, e.g., the secondary synchronization sequence is divided into 171 groups to represent 512 PCIs. It should be understand that when the number of PCIs to be represented varies, other extension solutions may be adopted.
Step 23: transmitting, by the terminal, a PCI of the neighboring cell to a network device, so that the network device determines the base station type according to the information indicating the base station type.
For example, the network side may be an evolved base station (eNodeB, eNB).
Corresponding to the UE side, the eNB may configure the corresponding relationship between a PCI group and a base station type, and then determine the base station type according to the PCI group to which the received PCI belongs. For example, if a PCI received by an eNB is 1, which belongs to a PCI group ranging from 0 to 412, since the base station type corresponding to the PCI group ranging from 0 to 412 is a macro base station, it may be determined that the base station type is a macro base station.
Further, the base station may determine a base station identity according to the base station type. For example, a UE transmits the base station identity carried in a 28-bits ECGI to an eNB, after the eNB receives the ECGI, the eNB acquires the base station identity from the ECGI according to the base station type since the base station type has been determined. For example, when the base station type is a macro base station, first 20 bits of the cell global identity are the base station identity; when the base station type is a home base station, 28 bits of the cell global identity are the base station identity.
According to this embodiment of the present invention, different base station types correspond to different PCI groups, therefore, the network side may determine an base station type according to a PCI and, thus, recognize the base station type accurately.
FIG. 3 is a schematic flow chart of a transmitting method according to another embodiment of the present invention. The method includes:
Step 31: determining, by a terminal, a base station type of a base station controlling a neighboring cell of a serving cell;
For example, reference may be made to the description about Step 11.
Step 32: transmitting, by the terminal, a cell global identity of the neighboring cell to the network device, where the cell global identity carries the base station type of the neighboring cell, so that the network device determines the base station type of the neighboring cell according to the base station type carried in the cell global identity.
For example, the cell global identity occupies 32 bits, and the base station type occupies first 4 bits of the cell global identity.
Further, the cell global identity may also carry a base station identity. For example, the cell global identity is an ECGI. Compared with the existing ECGI, in the ECGI according to this embodiment, bits used for identifying the base station type are needed to be added. Assuming that the number of bits used for identifying the eNB type is 4, the ECGI according to this embodiment occupies 32 bits. When the base station type of the base station controlling the neighbor cell is a macro base station, the base station identity occupies first 20 bits following the base station type of the cell global identity; when the base station type of the base station controlling the neighboring cell is a home base station, the base station identity occupies first 28 bits following the base station type of the cell global identity.
After receiving the ECGI, the eNB may determine the base station type according to the bits used for identifying the base station type firstly.
Specifically, in existing solutions, the EGCI of the macro base station occupies 28 bits, which includes a base station identity (eNB Id) and a cell identity (Cell Id), that is, for the macro base station, the EGCI occupies 28 bits=eNB Id (20 bits)+Cell Id (8 bits). For the home base station, the EGCI occupies 28 bits, which merely includes a base station identity (eNB Id), instead of including a cell identity (Cell Id), that is, as for the home base station, the EGCI occupies 28 bits=eNB Id (28 bits).
In this embodiment, the EGCI may occupy 32 bits, compared with the existing solutions, 4 bits used for identifying the base station type (eNB Type) are added. In particular, for the macro base station, the EGCI occupies 32 bits=eNB Type (4 bits)+eNB Id (20 bits)+Cell Id (8 bits); for the home base station, the EGCI occupies 32 bits=eNB Type (4 bits)+eNB Id (28 bits).
The eNB Type (eNB Type) may be represented as follow: for example, “0” is used to represent the macro base station, “1” is used to represents the home base station, and the remaining 3 bits may be retained. The eNB may extract first 4 bits from the EGCI, if the first 4 bits are 0, it is determined that the base station type is a macro base station, and if the first 4 bits are 1, it is determined that the base station type is a home base station.
