Embodiment 1

[0092] The application scenario of this embodiment is that a direct interface is established between HNBs, and a source HNB (sourceHNB) and a target HNB (target HNB) are connected to the same HNB GW. image 3 It is a flowchart of a method for obtaining routing information in Embodiment 1 of the present invention, such as image 3 As shown, the method for obtaining routing information in this example specifically includes the following steps:

[0093] Step 100a, the source HNB and the target HNB register with the HNB GW, and the sent message HNBREGISTER REQUEST carries information such as HNB Identity, Cell-Id, and CSG-Id;

[0094] In step 100b, the UE initially accesses the source HNB, and the source HNB registers the UE with the HNB GW through the UE registration process, and notifies the HNB GW of the U-RNTI of the UE in this step or subsequent steps, and the HNB GW records the U-RNTI of the UE. RNTI and the HNB where the UE is currently located;

[0095] Step 101, the UE ...

Embodiment 2

[0107] The application scenario of this embodiment is that the target HNB interacts with the HNB GW in advance to obtain the routing information of the source HNB, which is used in the cell update process of the user terminal; the source HNB and the target HNB are connected to the same HNB GW. Figure 4 It is a flow chart of the method for obtaining routing information in Embodiment 2 of the present invention, such as Figure 4 As shown, the method for obtaining routing information in this example specifically includes the following steps:

[0108] Step 200a, source HNB and target HNB register with HNB GW, and the message HNBREGISTER REQUEST sent carries information such as HNB Identity, Cell-Id, CSG-Id, and according to static configuration or dynamic address acquisition, source HNB and target HNB A direct interface is established between them, which can be a common Iur interface, or a newly added direct interface between HNBs;

[0109] Step 200b, the UE initially accesses t...

Embodiment 3

[0123] The application scenario of this embodiment is that the target HNB obtains the routing information of the source HNB in ​​advance through the direct interface, so as to use it in the cell update process of the user terminal; the source HNB and the target HNB are connected to the same HNB GW. Figure 5 It is a flow chart of the method for obtaining routing information in Embodiment 3 of the present invention, such as Figure 5 As shown, the method for obtaining routing information in this example specifically includes the following steps:

[0124] Step 300a, the source HNB and the target HNB register with the HNB GW, and the sent message HNBREGISTER REQUEST carries HNB Identity, Cell-Id, CSG-Id and other information, and according to static configuration or dynamic address acquisition, the source HNB and target HNB A direct interface is established between them, which can be a common Iur interface, or a newly added direct interface between HNBs;

[0125] In step 300b, t...

Abstract

The invention discloses a method for cell update. A home nodeB (HNB) acquires routing information of source HNB serving user equipment. The method comprises the following steps of: after a target HNB receives a cell update radio resource control (Cell Update RRC) message of the user equipment (UE), determining a service radio network controller (SRNC) of the UE as the source HNB according to the acquired routing information, and sending a control signaling for relocation to the source NHB; and initiating relocation aiming at the UE to the target HNB by the source HNB. The invention also discloses a system and the home nodeB for the cell update. The method, the system and the home nodeB are better suitable for a network structure with a network deployed by the home nodeB, and provide more perfect complementation for the current relocation flow.

Description

technical field [0001] The present invention relates to a cell update technology, in particular to a cell update method and system in a communication network including a home base station, and a home base station. Background technique [0002] Femto base stations are small, low-power base stations that are deployed in indoor places such as homes and offices. The main role of the femto base station is to provide users with a higher service rate and reduce the cost of using high-rate services, and at the same time, to make up for the lack of coverage of the existing distributed cellular wireless communication system. The advantages of femto base stations are affordable, convenient, low power output, plug and play, etc. [0003] figure 1 It is a schematic diagram of the composition structure of the home base station system. Such as figure 1 As shown, the home base station user is connected to the core network network through the home base station access network (HNB AN, Hom...
