Problems solved by technology

[0005] The present invention provides a handover control method in a home network, which is used to solve the problem that the emergency service bearer cannot be handed over to the UE's access-restricted cell when the cell is handed over in the home network, which leads to the reliability of the emergency service in the home network. and lower continuity issues

Embodiment 1

[0037] In this embodiment, assuming that the source HeNB and the target HeNB involved in the cell handover process belong to different MMEs, the MME to which the source HeNB belongs can be called the source MME, and the MME to which the target HeNB belongs can be called the target MME. Control is performed by the source MME.

[0038] Such as figure 2 As shown, the handover control method in the LTE network in which the HeNB is deployed specifically includes:

[0039] S201. The source HeNB initiates cell handover of the UE, selects a target home base station cell to which the UE needs to handover, and sends a first handover request message to the source MME, which includes bearer information of the UE on the side of the source home base station cell;

[0040] The UE will detect the signal strength of the cell it is currently camping on and adjacent cells. When the UE detects that the signal strength of the cell it is currently camping on is lower than the set threshold value ...

Embodiment 2

[0062] In this embodiment, assuming that the source HeNB and the target HeNB involved in the cell handover process belong to different MMEs, the MME to which the source HeNB belongs can be called the source MME, and the MME to which the target HeNB belongs can be called the target MME. Control is performed by the target MME.

[0063] Such as image 3 As shown, the handover control method in the LTE network in which the HeNB is deployed specifically includes:

[0064] S301. The source HeNB initiates a cell handover process of the UE, selects a target home base station cell to which the UE needs to handover, and sends a first handover request message to the source MME, which includes bearer information of the UE on the side of the source home base station cell;

[0065] S302. The source MME forwards the first handover request message to the target MME;

[0066] S303. The target MME obtains the list of CSG cells subscribed by the UE and the access mode of the target home base s...

Embodiment 3

[0080] In this embodiment, assuming that the source HeNB and the target HeNB involved in the cell handover process belong to the same MME, it is proposed in this embodiment that the handover control is performed by the MME.

[0081] Such as Figure 4 As shown, the handover control method in the LTE network in which the HeNB is deployed specifically includes:

[0082] S401. The source HeNB initiates the cell handover process of the UE, selects the target home base station cell to which the UE needs to handover, and sends a first handover request message to the MME, which includes bearer information of the UE on the side of the source home base station cell;

[0083] S402. The MME obtains the list of CSG cells subscribed by the UE and the access mode of the target home base station cell;

[0084] S403. The MME determines that the target home base station cell is a UE's access-restricted cell;

[0085] S404. The MME further confirms that the UE has an emergency service bearer b...

Abstract

The invention discloses a switching control method and a device of a home network, which are used for solving the problem that in the existing home network, emergency business load cannot be switched to a UE access-restricted area when area switching is carried out, so the reliability and continuity of the emergency business in the home network are caused to be lower. The switching control method of the home network comprises the steps of: receiving first switching request information which requires to switch UE from a source home base station area to a targeted home base station area, wherein UE bearing information from the side of the source home base station area is contained; and when the targeted home base station area is judged to be the UE access-restricted area, and if UE is judged to have emergency business load which is under construction or activated at the side of the source home base station area according to the bearing information, the emergency business load is controlled to be switched to the targeted home base station area. The invention improves the reliability and the continuity of the emergency business in the home network.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a switching control technology in a home network. Background technique [0002] A femtocell is a base station with low transmission power for indoor scenarios. It is purchased and installed by the owner of the femtocell. When the femtocell is connected to the network of a mobile communication operator, it can provide mobile communication services for mobile users. An important feature of a femtocell different from a macro base station (such as Base Station, NodeB, eNodeB) is: the backhaul link from the femtocell to the mobile communication network is usually the broadband access link of the femtocell owner, and the femtocell owner Usually you pay for this broadband access link. Therefore, in order to better provide mobile communication services for owners of femtocells, the concept of CSG (Closed Subscriber Group, Closed Subscriber Group) is introduced. The so-call...
