Abstract
The invention discloses a method and device for configuring and acquiring a cell identity, and relates to the field of communication. The invention solves the problem that the unique identity of the cell can not be determined within a certain application range since the physical identities of the cells are confused in the prior art. The method comprises the following steps: receiving a measurement report, which comprises a main scrambled code and an auxiliary scrambled code; and determining the unique identity of the cell according to the main scrambled code and the auxiliary scrambled code of the cell. The embodiment of the invention is mainly used when the user device reports the measurement report.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and device that disposes and obtain cell ID.
Background technology
At 3GPP (3rd Generation Partnership Project, third generation partner program) in the standard agreement, Serving cell sending measuring control messages, and a series of process such as UE reporting measurement reports is all come distinguishing cell by sub-district physical label (promptly main scrambler).Under the situation of only arranging grand net, or cell density is not under the very big situation, in certain scope, as long as macrocell and its adjacent area do not reuse same main scrambler just can the unique identification sub-district; Wherein, grand net is made of macrocell, because the coverage of macrocell is bigger, the quantity that macrocell is set within the specific limits is fewer.
Yet, at UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) and in system such as LTE, when introducing HNB (Home Node B, Home eNodeB) after the notion, because the coverage of this Home eNodeB is smaller, the Home eNodeB that may have a lot of quantity in the certain limit, cause a macrocell may exist number to be far longer than 512 adjacent areas of related protocol regulation in the prior art, described adjacent area comprises macrocell and Home eNodeB etc., just may exist at least two sub-districts to use identical main scrambler to come identifying cells around the so described macrocell in the adjacent area, thereby make described macrocell around the adjacent area can not know unique differentiation adjacent area around it by principal mark, Here it is, and so-called sub-district physical label is obscured.
Because the situation that may exist the sub-district physical label to obscure within the specific limits, when UE reports the measurement report of a sub-district, if this employed main scrambler in sub-district that UE reports, in its adjacent area scope, exist at least two adjacent areas to use described main scrambler, what this sub-district just can't judge that UE reports so specifically is the measurement report of which sub-district, and this will switch to the sub-district bring certain puzzlement.
Summary of the invention
Embodiments of the invention provide a kind of method and device that disposes and obtain cell ID, solved because the sub-district physical label is obscured, and can't determine sub-district uniquely identified problem in certain range of application.
For achieving the above object, embodiments of the invention adopt following technical scheme:
A kind of method of obtaining cell ID comprises:
Reception comprises the main scrambler of sub-district and the measurement report of auxilliary scrambler;
According to the main scrambler and the auxilliary scrambler of described sub-district, determine the unique identification of described sub-district.
A kind of method of obtaining cell ID comprises:
Receive the measurement control messages that network side sends;
According to described measurement control messages the neighbor cell of sub-district, subscriber equipment place is measured;
Satisfy the sub-district of measuring reported event if detect, and described sub-district will comprise that for adopting the sub-district of main scrambler and auxilliary scrambler identifying cells subzone main scramble and auxilliary scrambler measurement report send to network side.
A kind of method of configuring community identification comprises:
Detect the quantity of having created the sub-district in the preset range;
If detect the quantity of having created the sub-district in the described preset range more than or equal to default quantity, then be new main scrambler of cell allocation of creating, and for the sub-district with described main scrambler distribute respectively one with the corresponding scrambler group of this main scrambler in different auxilliary scramblers;
If detect the quantity of having created the sub-district in the described preset range, then be different from the main scrambler of other sub-districts for new one of the cell allocation of creating less than default quantity.
A kind of network side apparatus comprises:
Receiving element is used to receive the main scrambler that comprises the sub-district and the measurement report of auxilliary scrambler;
Determining unit is used for main scrambler and auxilliary scrambler according to described sub-district, determines the unique identification of described sub-district.
A kind of subscriber equipment comprises:
Receiving element is used to receive the measurement control messages that network side sends;
Measuring unit is used for according to described measurement control messages the neighbor cell of sub-district, subscriber equipment place being measured;
Transmitting element be used for satisfying the sub-district of measuring reported event if described measuring unit detects, and described sub-district will comprise then that for adopting the sub-district of main scrambler and auxilliary scrambler identifying cells subzone main scramble and auxilliary scrambler measurement report send to network side.
A kind of device of configuring community identification comprises:
Detecting unit is used to detect the quantity of having created the sub-district in the preset range;
First allocation units, be used for if described detecting unit detects the quantity of having created the sub-district in the described preset range more than or equal to default quantity, then be new main scrambler of cell allocation of creating, and for the sub-district with described main scrambler distribute respectively one with the corresponding scrambler group of this main scrambler in different auxilliary scramblers;
Second allocation units are used for then being different from the main scrambler of other sub-districts for new one of the cell allocation of creating if described detecting unit detects the quantity of having created the sub-district in the described preset range less than default quantity.
After adopting technical solution of the present invention,, be that it distributes auxilliary scrambler, make within the specific limits sub-district assist the mode that scrambler combines and distinguished by main scrambler or main scrambler for the sub-district that can't distinguish with main scrambler; And owing to adopt main scrambler and auxilliary scrambler to identify jointly for the identical sub-district of main scrambler, make the sub-district of user equipment to report can both determine unique sign at network side, make network side when switching to the sub-district of its service for subscriber equipment, avoided because the main scrambler of sub-district is obscured, and the problem that switching can't be carried out.
