Embodiment 1
[0121] Example 1 contains Figure 7 and Figure 8 , in this embodiment, the destination HNB gateway is allocated by the source HNB gateway.
[0122] Such as Figure 7 as shown,
[0123] 1) HNB gateway handover notification. The source HNB gateway needs to move the HNB connected to it to other HNB gateways due to maintenance, performance, failure and other reasons (see 1.c description). Send the home base station gateway switching notification message to notify the home base station, the message includes the reason, the context of the idle UE (IMSI, TMSI or P-TMSI of the UE) (optional), the ACL of the home base station (optional), the new home base station Gateway information.
[0151] Example 2 contains Figure 9 , in this embodiment, the destination gateway is assigned by the operation and maintenance node. Such as Figure 9 Shown:
[0152] 1) HNB gateway handover notification. The source HNB gateway needs to move the HNB connected to it to other HNB gateways due to maintenance, performance, failure and other reasons (see 1.c description). The HNB gateway handover notification message is sent to notify the HNB, the message includes the reason, the context of the idle UE (IMSI, TMSI or P-TMSI of the UE) (optional), and the ACL of the HNB (optional).

Abstract
The invention discloses a method for replacing a service gateway for a household base station, which comprises the following steps that: a source household base station gateway notifies the householdbase station to switch the gateway; the household base station acquires information on a destination household base station gateway; and the household base station registers to the destination household base station gateway. For the household base station providing services, the method can dynamically switch the household base station gateway connected with the household base station providing services so as not to affect the services just provided by the household base station.
Description
technical field [0001] The present invention relates to the field of wireless communication, and more specifically relates to a method for dynamically switching a home base station gateway (HNB-GW) that provides services for a home base station (HNB). Background technique [0002] The femto base station can be placed in the user's home to achieve indoor coverage based on the family, access the ISP network through xDSL, and connect to the femto base station gateway through the Iu-h interface based on IP bearer. The femto base station gateway is connected to the home base station gateway through the standard Iu interface The core network (CN), the user terminal (UE) accesses the home base station through the Uu interface, and the home base station network managementsystem (HNB Management System) manages the home base station through the Iu-hm interface. The brief network topology diagram of the home base station is as follows: figure 2 shown. [0003] Compared with traditio...
