Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a system, and an apparatus for triggering handover.
Background
Home base station (Home NodeB) is a leading technology and a hot topic in the field of 3G (3rd Generation, third Generation mobile communication technology). The 3G home base station can be seamlessly connected with the original network equipment of an operator, the existing broadband access resources of the user are fully utilized, and finally, FMC (Fixed-Mobile Convergence) services are provided for the user. Through the 3G home base station, a large amount of mobile services can be absorbed by the indoor home base station, the number of macro cells of an operator is greatly reduced, a large amount of equipment investment cost and maintenance cost are saved for the operator, and the method is the most economical indoor signal coverage technology.
Now, as the mobile communication technology is more and more diversified, the system devices are diversified to meet the diversified user requirements, and the home indoor coverage and enterprise-level internal coverage base stations and other limited networks which are concerned are generated. Such a Network may be a Home base station, a Home Cell (Home Cell), an Access Point (Access Point), a Private Network (Private Network), a Private Cell (Private Cell), etc., and also a restricted Network of some specific frequency layers. Recently, the 3GPP introduced the concept of Closed Subscriber Group (CSG), and if a user subscribes to the CSG or is added to the CSG by the owner of the CSG, the user is allowed to normally reside in the CSG cell and apply for a service; and the user who has not signed a contract or is not added to the CSG by the CSG owner cannot normally reside in the CSG cell or initiate the service.
In the 3G network, since the UE (User Equipment) does not know which private cells can be accessed, the access restriction of the private cells in the prior art is implemented by a network denial manner. That is, no matter whether the UE has the access right or not, the UE may initiate a location area update request to the network side, and the network side discriminates whether the user has the right or not. For the authorized users, the network side allows the access, and for the unauthorized users, the network side refuses the access.
In order to limit invalid accesses initiated by unauthorized users, and in conjunction with the network rejection mode, the prior art also introduces the concept of white list, that is, cells allowed to be accessed by the UE are listed as a white list and stored in the user card of the UE. However, when the user accesses the network for the first time, or the white list configuration of the UE is different from the network side, the user without authority may also initiate access to the network.
When the UE performs cell handover, in the prior art, a source radio network controller performs handover decision according to a neighbor cell list and according to an event of a measurement report reported by the UE, that is, performs handover decision according to the quality of a downlink signal measured by the UE.
However, the existing standard specifies that the number of neighboring cells included in the neighboring cell information sent to the UE by the radio network controller cannot exceed 32 × 3, that is, the number of neighboring cells of each type (same frequency, different frequency, or different system) is 32 at most, so when the number of home base station cells of one type is large and exceeds 32, some home base station cells cannot send measurement control messages to the UE through an air interface, and therefore, the UE without self-search capability cannot be triggered to perform cell measurement, and therefore, the UE without self-search capability cannot perform handover from a macro cell to a home base station cell.

Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
The embodiment of the invention provides a switching triggering method, which realizes that a large number of UE without self-searching capability can switch from a macro cell to a home base station cell when the macro cell cannot issue measurement control with the neighboring cell information of a large number of home base station cells to the UE under the condition that a network is limited by the number of neighboring cells which cannot be more than 32 x 3. The UE in the embodiment of the present invention may be a mobile terminal such as a mobile phone, a notebook computer, or a PDA (Personal Digital Assistant).
Example one
An embodiment of the present invention provides a method for triggering handover, and as shown in fig. 1, the method for triggering handover provided in this embodiment specifically includes:
step S101, a home NodeB receives uplink physical information of user equipment UE sent by a wireless network control device of an adjacent macro cell, wherein the UE is signed UE of the home NodeB.
When a UE establishes a connection with a macro cell, a radio network controller of the macro cell (i.e., a source radio network controller of the UE) allocates uplink physical information to the UE. The Radio network control device includes an SRNC (Source Radio network controller), an S-NodeB + (Source-NodeB +, Source node +) or an E-NodeB (Evolved-NodeB). The following embodiments two, three and four take the source radio network controller SRNC as an example.
The uplink physical information includes: frequency information (Frequency Info), DTX (Discontinuous transmission)/DRX (Discontinuous reception) configuration information, Uplink Dedicated Physical channel information (Uplink Dedicated dpch Info), or Enhanced Dedicated channel information (E-DCH Info). Wherein, the uplink dedicated physical channel information includes uplink scrambling code information of the UE.
The sending, by the radio network control device, the uplink physical information of the user equipment UE to the home base station specifically includes:
(1) the wireless network control equipment acquires UE subscription information of an adjacent home base station of the wireless network control equipment, and then the wireless network control equipment sends uplink physical information of the subscribed UE of the adjacent home base station to the adjacent home base station through an Iur interface according to the UE subscription information. In addition, the radio network control device may also establish a radio link with the neighboring home base station through the Iur interface, and send uplink physical information of the subscribed UE of the neighboring home base station to the neighboring home base station through the radio link. Or alternatively.
(2) The radio network control device obtains the information of the femtocell cell subscribed by the UE through the measurement report reported by the UE, for example: cell ID (IDentity), RAT (Radio Access Technology ) type, center frequency point of the femto cell, offset, DRX information, priority information, minimum uplink/downlink signal quality threshold for selecting handover to the cell, and the like. And then the radio network control equipment sends the uplink physical information of the UE to the home base station subscribed by the UE through an Iur interface or a radio link.
Step S102, searching corresponding UE according to the uplink physical information. After receiving the uplink physical information, the neighboring home base station of the radio network control device searches at an air interface according to the uplink physical information, and searches for the UE corresponding to the uplink physical information.
Step S103, after searching the corresponding UE, sending a switching indication message to the wireless network control equipment, thereby triggering the UE to switch from the macro cell to the home base station cell.
After the UE corresponding to the uplink physical information is searched, the home base station sends a switching indication message to the wireless network control equipment of the adjacent macro cell, so that the UE is triggered to switch from the macro cell to the home base station cell, and the switching indication message comprises the uplink physical information of the UE and the information of the home base station cell.
In the embodiment of the present invention, the handover indication message may specifically be a radio link recovery message.
In the embodiment of the invention, when the wireless network control equipment of the macro cell and the home base station have no Iur interface, the information interacted between the wireless network control equipment and the home base station is forwarded through a related core network, namely, the information interaction between the wireless network control equipment and the home base station is carried out through a logical Iur interface. Or,
when there is no Iur interface between the radio network control device of the macro cell and the home base station, an air interface function similar to that of the UE may be implemented on the home base station, and a message sent by a physical entity or a logical entity of a NodeB controlled by the radio network control device of the macro cell is received through the air interface, so as to complete information interaction between the radio network control device and the home base station.
In the method for triggering the switching, the home base station receives uplink physical information of the subscribed UE of the home base station, which is sent by the wireless network control equipment of the adjacent macro cell, searches the corresponding UE according to the uplink physical information, and sends a switching indication message to the wireless network control equipment of the macro cell after the corresponding UE is searched, so that the UE is triggered to switch from the macro cell to the home base station cell, and a large number of UEs without self-searching capability can switch from the macro cell to the home base station cell.

The UE subscription information of the neighboring hnb includes an IMSI (International Mobile Subscriber Identity) or a T-IMSI (Temporary-International Mobile Subscriber Identity) of the UE subscribing to the neighboring hnb, and the like.
The source wireless network controller can acquire UE subscription information of adjacent home base stations from a core network through configuration of a background O & M (Operation and Maintenance); or,

The handover indication message includes uplink physical information of the UE and information of the home base station cell.
In step S207, the source radio network controller of the macro cell receives the handover indication message sent by the neighboring femto, thereby triggering the handover of the UE from the macro cell to the femto cell.
