Embodiment
Below in conjunction with the drawings and the specific embodiments the present invention is elaborated.
The present invention is mainly used in the subscriber equipment (UE of mobile communication system, User Equipment), its inventive concept is: with the HNB sub-district (area of coverage of HNB node, its concrete coverage is relevant with the power of HNB node) bind with its geographical location information, when the current geographic position of UE mates with the geographical location information of binding the sub-district, carry out HNB the discovery flow process (with cell downlink synchronously after, the reading system broadcast message, coupling SIB9 (system information block, system information block).
In the specific embodiment of the invention, the discovery procedure of HNB comprises that mainly the initialization flow process of two flow process: UE and the HNB of UE find flow process.
The initialization flow process of UE: obtain the geographical location information of HNB sub-district, store in the subscriber equipment.
The HNB of UE finds flow process: when UE not in the HNB sub-district, finds the geographical location information coupling of current geographical location information and binding HNB sub-district, execution HNB cell search process; If UE has been in HNB sub-district (UE has successfully resided in the HNB sub-district), then ignore this process.
Geographical location information comprises the current geographic position information of UE, and the geographical location information of binding HNB sub-district, can pass through GPS (Global Position System, global positioning system) acquisition.GPS is the global positioning system of the U.S., utilizes satellite transmitted signal, obtain longitude and latitude, highly, geographical location information such as speed, also have the dipper system and the Muscovite Venus system of China therewith like the technology type.
Need to prove that HNB is a point from conceptive seeing, but on physical angle, its actual service coverage area that refers to the base station of HNB configuration is called HNB service area or HNB sub-district.But because the geographical location information geographical location information such as longitude and latitude of a point normally, thereby, the geographical location information of HNB as herein described, it can be the geographical location information of the position, base station of HNB configuration, also can be near the geographical location information of any arbitrarily of position, base station, or the geographical location information of a plurality of points on the different directions of HNB cell edge.When carrying out the geographical location information coupling, can adopt accurate coupling, be that the current geographic position information of UE and the geographical location information of HNB sub-district mate fully, also can adopt fuzzy matching, it is the current geographic position information of UE, in certain deviation range of the geographical location information of HNB sub-district, for example the geographical location information that is in the HNB sub-district when the current geographic position information of UE is the center, in the round zone with certain radius (for example 10 meters), think that then the current geographic position information of UE and the geographical location information of HNB sub-district mate.During near the geographical position of putting geographical position, HNB sub-district is set to base station geographic position or base station, because the base station generally is in center of housing estate, the geographical location information of a point can only be set then, the canned data amount is few, and matching operation is simple.When being set to cell edge some in geographical position, HNB sub-district, a plurality of points on the different directions then generally need be set, so that be adapted to the possibility that the user enters into the HNB sub-district from different directions, the mode of choosing of this geographical location information, although amount of information is more, matching operation is complicated, but can find that once entering the HNB sub-district user enters the user, thereby can make user resident HNB sub-district more early.
As Fig. 1, the concrete steps of the initialization flow process of UE comprise:
Step 1:UE powers on and is working properly.
Step 2:UE obtains the geographical location information of wishing resident HNB sub-district.Geographical location information obtains by the GPS module among the UE, similarly, also can utilize dipper system or Venus system to obtain.
Step 3: obtain and wish resident HNB system information of subdistricts.System information comprises layer three sub-district ID (Identity, sign), physical district ID, up-downgoing frequency, home (e) node ID (HNBID) etc.
Step 4: the geographical location information of HNB sub-district and the cell system information of HNB are bound, stored in the memory of UE, initialization finishes.
Need be appreciated that binding is exactly that the geographical location information of HNB sub-district is related with the foundation of home (e) node information, home (e) node information can be the home (e) node title, also can be in the system information that goes up in the example one or more.For example, geographical location information and its home (e) node ID with the HNB sub-district binds.
As Fig. 2, the HNB of UE finds that flow process comprises:
The first step: the UE system powers on, operate as normal;
Second step: the geographical location information that reads the HNB sub-district of binding;
The 3rd step: obtain the current geographic position information of UE, relatively whether the geographical location information with the HNB sub-district of binding mates, to judge that UE is whether in the HNB sub-district.Coupling then shows UE in the HNB sub-district, otherwise UE is not in the HNB sub-district.When UE in the HNB sub-district, then carried out for the 6th step, otherwise carried out for the 4th step.
The 4th step: start relatively timer, this comparison timer is used for periodically the geographical location information of the HNB sub-district of the real-time geographic positional information of UE relatively and binding, i.e. timer overtime at every turn (timing to) is relatively then carried out the comparison of geographical location information of the HNB sub-district of the real-time geographic positional information of a UE and binding.
The 5th step: timer expiry relatively, carry out the real-time geographic positional information of UE and the comparison of the geographical location information of the HNB sub-district of binding, coupling is then carried out next step, compares timer otherwise reset, and waits the overtime next time of timer to be compared.
The 6th step: carry out the search procedure of HNB sub-district, so that obtain the HNB system information of subdistricts.As previously mentioned, can in the initialization flow process, obtain the HNB system information of subdistricts, and store in the memory of UE with the geographical location information of HNB sub-district, like this, in the Cell searching of this step, only need carry out descending passing through, also be, by the HNB system information of subdistricts that in UE, prestores, can accelerate cell search process.Certainly, if do not carry out the process that system information is obtained and preserved in initialization procedure, then Cell searching need carry out to obtain required whole system informations comprehensively.
The 7th step: obtain the HNB system information of subdistricts, it is resident to carry out the HNB sub-district.When resident, can whether select whether to carry out resident in the HNB sub-district under the UE according to this HNB sub-district.UE a plurality of HNB sub-district of can contracting, general only signatory one, this signatory HNB sub-district is exactly the HNB sub-district under the UE, when resident, UE judges according to CAMEL-Subscription-Information (for example HNBID), if judge this HNB sub-district and nonself signatory sub-district, does not then carry out resident; If judge it is the signatory sub-district of self, then carry out resident.
The 8th step: the resident success in HNB sub-district stops the comparison timer.
In the 9th step, after UE leaves the HNB sub-district, then restart the comparison timer.At this moment, can leave from the HNB sub-district, thereby relatively timer begins startup work, carry out the periodicity comparison of current geographic position information with the geographical location information of the HNB sub-district of binding of UE according to sub-district switching judging UE.
As Fig. 3, the discovery device of the home (e) node of the specific embodiment of the invention comprises:
The geographical location information comparison module is used to obtain the geographical location information of home (e) node; And obtain the subscriber equipment current geographic position information in real time, and compare with the geographical location information of home (e) node;
