Problems solved by technology

Since the MME cannot know the CSG supported by the heNB GW and the TA of the heNB in ​​the public access mode supported by the MME, it cannot notify the heNBGW which mode of the heNB it needs to page the UE on, resulting in a waste of paging resources

Embodiment 1

[0049] see image 3 , image 3 It is a flow chart of Embodiment 1 of the present invention. Such as image 3 As shown, the HeNB GW establishes a control plane connection with the MME; the HeNB GW sends an establishment request message to the MME, and the establishment request message includes the CSG supported by the HeNB GW and the corresponding location area set TA1 and / or the heNB in ​​the public access mode supported The corresponding location area set TA2. After confirming the reception of the establishment request message, the MME returns a request message response to the HeNB GW.

[0050] In addition, when the HeNB GW has established a control plane connection with the MME, and the CSG supported by the heNB GW and the corresponding location area set TA1 and / or the location area set TA2 corresponding to the heNB in ​​the supported public access mode changes, the heNB GW Initiate an update request to the MME; the update request includes the updated CSG supported by th...

Embodiment 2

[0060] see Figure 4 , Figure 4 It is a flow chart of Embodiment 2 of the present invention. Such as Figure 4 As shown, the HeNB initiates a connection establishment request to the heNBGW; if the HeNB belongs to the CSG mode, it notifies the heNB GW of the CSG supported by the GW and the corresponding location area; if the HeNB belongs to the public access mode, it notifies the heNB GW of the location area corresponding to the public access mode supported .

[0061] Or, the HeNB has established a connection with the heNB GW, the CSG supported by the heNB in ​​the CSG mode and the corresponding location area are updated, or the location area supported by the heNB in ​​the public access mode changes, the heNB initiates an update request to the HeNB GW. After the heNB GW confirms receiving the connection establishment or update request, it returns a response to the HeNB connection establishment or update request.

[0062] The HeNB GW judges that the location area set TA1 co...

Embodiment 3

[0071] see Figure 5 , Figure 5 It is a flow chart of Embodiment 3 of the present invention. Such as Figure 5 As shown, the UE sends a NAS message to the MME, and the NAS message may be an attach request, a service request, or a location update request. The content of the NAS message is transparent to the heNB GW, but needs to be transmitted through the interface between the heNB GW and the MME. If the UE accesses from the heNB in ​​CSG mode, the NAS message carries the CSG and the corresponding location area; if the UE accesses from the heNB in ​​the public access mode, the NAS message carries the location area corresponding to the heNB in ​​the public access mode; The MME adds the closed user group information and the corresponding location area carried in the NAS message to the closed user group set supported by the home base station gateway and the corresponding location area set TA1 and / or the public access mode carried in the NAS message The location area below is ...

Abstract

The embodiment of the invention discloses a method and a device for optimizing paging parameters, wherein the method comprises the following steps: acquiring a closed user group supported by a home base-station gateway and a corresponding location-area set TA1 and / or a location-area set TA2 corresponding to a home base station with a public access mode; generating paging parameters according to the closed user group supported by the home base-station gateway and the corresponding location-area set TA1 and / or the location-area set TA2 corresponding to the home base station with the public access mode and related information of users, wherein the related information of users includes a white list, a shifting list and a location-area list of users; and the device comprises an acquisition unit and a paging parameter generating unit. The method and the device of the embodiment can notice the home base station gateway which home base stations with the closed user group mode and / or the public access mode can carry out user paging and reduce the waste of paging resources.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method and device for optimizing paging parameters. Background technique [0002] At present, the femtocell network is attracting more and more attention at home and abroad. The control plane architecture of the femtocell network is as follows: figure 1 As shown, a home base station (heNB, home evolved NodeB) is connected to a home base station gateway (heNB GW, Home evolved NodeB GateWay); the heNB GW is then connected to a mobility management entity (MME, Mobility management entity). The heNB GW plays a converging role to avoid excessive load on the MME caused by too many heNBs directly accessing the MME. User Equipment (UE, User Equipment) can connect to the operator's mobile network through a common IP access network (such as digital subscriber line, cable broadband) through a home wireless access point, using spectrum of the wireless ...
