Embodiment 1

[0131] Embodiment 1 is based on the premise that the RG works in routing mode, that is to say, the CPE address is allocated to the RG, and it can be determined whether the H(e)NBs share a backhaul according to whether the CPE addresses are the same. The main idea of ​​Embodiment 1 is: when the H(e)NB is powered on, it needs to obtain the IP address of the CPE, and when registering with the H(e)MS, report it to the H(e)MS, and the H(e)MS is the CPE H(e)NBs with the same address select the same H(e)NB GW / MME. When H(e)NB registers with H(e)NB GW / MME, it also carries the CPE address, so that H(e)NB GW can judge whether H(e)NB is connected to the same backhaul according to whether the CPE address is the same down, see Figure 4 .

[0132] When the UE switches between H(e)NBs under the same backhaul, both H(e)NB GW and MME can perceive it. At this time, H(e)NB GW or MME accepts the resource request from the target side (even if the Insufficient), to complete the switch, see Fi...

Embodiment 2

[0164] Embodiment 2 is based on the premise that the RG works in routing mode. The basic idea and mechanism are basically the same as in Embodiment 1. The difference in support lies in the way of transmitting the CPE address. The following describes the differences accordingly:

[0165] 501. Same as 401.

[0166]502. H(e)NB-1 establishes an IPsec tunnel between H(e)NB-1 and SeGW. (No CPE IP address sent, or even if sent, H(e)NB-1 does not process / perceive).

[0167] 503. Establish / update a binding relationship between the SeGW and the H(e)NB PF.

[0168] 503a. Triggered by step 502, SeGW sends the address of H(e)NB-1 (assigned to it in step 502, prior art) and CPE address to H(e)MS (the message passes between SeGW and H(e)MS The interface between is newly added for the present invention). This step happens before 504.

[0169] 504. H(e)NB-1 registers with H(e)MS, H(e)MS selects H(e)NB GW / MME for H(e)NB-1, and feeds back its IP address to H(e)MS )NB-1.

[0170] After 50...

Embodiment 3

[0191] The above two embodiments are based on the premise that the RG works in routing mode. At this time, the CPE address is the RG address, and the H(e)NB connected to the same RG (that is: belonging to the same backhual) reports to H(e) ) The CPE addresses of the MS and the H(e)NBGW / MME are the same, and the H(e)NB GW judges whether multiple H(e)NBs are under the same backhaul based on the same CPE addresses.

[0192] When the RG works in bridge mode, the CPE address is assigned to the H(e)NB, and even if multiple H(e)NBs connected to the same RG share a backhaul, their CPE addresses are different. At this time, the H(e)NB GW / MME cannot judge whether these H(e)NBs are under the same backhaul based on the CPE address. Here we make the following corrections and enhancements, which are applied to the bridge mode.

[0193] After the H(e)NB registers with the H(e)MS, the H(e)MS queries the fixed network (for example, the fixed network address server) for the backhual information...

Abstract

The invention discloses a method and a system for realizing resource management control in a switching process. The method comprises the following steps that: after being electrified, a plurality of first network elements under the same fixed network link access to the same second network element; when the user equipment (UE) switch between the first network elements under the fixed network link, the second network element executes admission control; wherein the first network elements are home Evolved Node Bs (HeNB), and the second network element is a HeNB gateway (GW) or a mobility management entity (MME); or the first network elements are home Node Bs (HNB), and the second network element is a HNBGW. The method and the system can avoid the problem of switching failure of the UE when switching between the H(e)NBs under the same fixed network link, wherein the switching failure may be caused by the lack of resource.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for realizing resource management control during handover. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3GPP) consists of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN), mobile management Unit (Mobility Management Entity, MME), Serving Gateway (Serving Gateway, S-GW), Packet Data Network Gateway (Packet Data Network Gateway, P-GW), Home Subscriber Server (Home Subscriber Server, HSS). [0003] figure 1 It is a schematic diagram of the architecture of an evolved home base station (Home evolved NodeB, HeNB) accessing EPS in a non-roaming scenario according to related technologies, as shown in figure 1 As shown, MME is connected with EUTRAN, S-GW and home base station gateway (HeNB GW), and is responsible for mobility management, processing of non-access stratum signaling...
