Problems solved by technology

Therefore, the source HNB needs to first determine whether the target HNB is under the same gateway as it, and then the base station takes a different behavior from the normal handover process. According to the current definition, the source HNB cannot determine whether the target HNB is under the same gateway as it. Under the control of the same gateway, therefore, the source HNB cannot make the correct follow-up behavior, that is, send the encrypted information to the target HNB through the gateway

Embodiment 1

[0021] Embodiment 1 describes the handover process between the HNB and the HNB under the UMTS system.

[0022] The home base station management entity (HMS) configures necessary parameters for the base station gateway (referred to as the gateway), and the parameters include the RNC identifier of the base station gateway and the routing area list (LAI / RAIlist) supported by the gateway. The femto base station management entity may be referred to as a second entity.

[0023] Such as image 3 As shown, in step 301, a certain home base station (referred to as the first entity) is powered on and turned on. First, the home base station searches for surrounding cells and receives broadcast information from surrounding cells, such as the cell ID and the identification LAI / RAI of the cell routing area. .

[0024] In step 302, the HMS configures necessary parameters for the HNB, and the HNB configuration parameters include the RNC ID of the HNB, and the cell ID of the HNB cell. Curren...

Embodiment 2

[0050] Embodiment 2 describes the handover process between the HNB and the HNB in ​​the long term evolution system.

[0051] Such as Figure 4 As shown, when the home base station is turned on, first, the home base station (that is, the first entity) needs to exchange messages with the base station management entity, and obtain configuration parameters from the second entity home base station management entity, and the first entity home base station can use Embodiment 1 In the method, information is obtained from the HNB management entity, and this information is used to determine whether the adjacent HNB cell is under the same gateway as the first entity. In the LTE system, the HNB gateway uses a unique set of area identifiers TAI, and the HNB management entity can send the gateway identifier and the TAI List supported by the gateway to the HNB. When the first entity HNB receives the user's measurement report, the measurement report includes the identity of the adjacent HNB ...

Abstract

The invention relates to a method for indicating a home base station relation, comprising the following steps of: transmitting a message to a second entity by a first entity, wherein the message comprises the identification of the first entity; and transmitting a message to the first entity by the second entity, wherein the message comprises information for judging whether an adjacent home base station cell is under the same gateway with the first entity. By the method of the invention, when UE (User Equipment) moves among home base stations, the continuous reception of data can be maintained and the signaling interaction with a core network is reduced so as to reduce the load of the core network, and the invention can support an old-version core network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for indicating the relationship between home base stations. Background technique [0002] With the development of communication technology, the mobile communication system has developed into a System Architecture Evolution (SAE) system, which includes the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and the core network. The schematic diagram of the SAE system architecture is as follows figure 1 As shown, the eNB belongs to the radio access network and is responsible for providing the mobile phone with a wireless interface to access the SAE system. The eNB is connected to the mobility management entity MME and the user plane entity S-GW through the S1 interface. The MME is responsible for managing the mobile context and session context of the user equipment, and saving the user's security-related information. The S-GW mainly provides the function of the...
