Embodiment 1

[0146] Embodiment 1 (for the embodiment of "the UE acquires the information of the bearer participating in the 3GPP inter-access handover"):

[0147] E-UTRAN, UTRAN, and GERAN are access technologies defined by the standardization organization 3GPP. The access technology currently used by the UE to access the network is E-UTRAN, and the UE currently has IP flow 1, IP flow 2, and IP flow 3, where IP flow 1 and IP flow 2 are transmitted through bearer 1, and IP flow 3 is transmitted through bearer 2 transmission.

[0148] The ANDSF policy in the UE includes multiple ISRP rules, and the UE selects an ISRP rule. The selected ISRP rule indicates that the priority of E-UTRAN is 1, the priority of UTRAN is 2, the priority of WLAN is 3, and the priority of GERAN 4. 1 is the maximum and 4 is the minimum.

[0149] The UE matches the currently transmitted IP flow with the IP flow description information in the selected ISRP rule, and learns that IP flow 1 and IP flow 3 match the IP flo...

Embodiment 2

[0167] Embodiment 2 (for the embodiment of "the UE sends information about bearers participating in 3GPP inter-access handover to the access device"):

[0168] In the E-UTRAN, the UE is currently transmitting IP flow 1, IP flow 2, IP flow 3, and IP flow 4, and bearers for transmitting these IP flows are bearer 1, bearer 2, bearer 3, and bearer 4 respectively. According to the relative priority between each 3GPP access technology and WLAN in the ANDSF policy, the UE knows that when the UE switches to UTRAN, bearer 1 and bearer 3 participate in the handover, and when the UE switches to GERAN, bearer 2 participates in the handover. The process of providing the UE with the bearer information of the UE participating in the 3GPP inter-access handover to the access device through the two methods of the present invention is respectively introduced below.

[0169] method one:

[0170] The UE can carry the information of the bearers participating in the 3GPP inter-access handover in di...

Embodiment 3

[0176] Embodiment 3 (for the embodiment of "the UE updates the bearer information participating in the 3GPP inter-access handover")

[0177] Based on the scenario of Embodiment 2: the UE is in the E-UTRAN, and is currently transmitting IP flow 1, IP flow 2, IP flow 3, and IP flow 4, and the bearers for transmitting these IP flows are bearer 1, bearer 2, and bearer 3, respectively. Bearer 4.

[0178] Since the network updates the ANDSF policy in the UE, the priority between GERAN and WLAN changes, so when the UE switches to GERAN, bearer 2 also needs to be switched to GERAN. Therefore, the UE needs to modify the bearer information stored in the network to participate in the 3GPP inter-access handover to (). The process of updating the UE's bearer information stored in the network side entity and participating in the 3GPP inter-access handover in the UE through the two methods of the present invention is introduced respectively below.

[0179] method one:

[0180] Since there a...

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a host switching method, system and device to solve the problem of the prior art that when UE is switched among different 3GPP accesses, all hosts of the UE are switched on the network side, and therefore signaling overheads are increased. The method comprises the steps that the UE determines access information containing the target access technology and a specific host, wherein the specific host is a host which needs to be switched to a target access network using the target access technology when the UE is switched among 3rd Generation Partnership Project (3GPP) accesses; network-side equipment is notified of the determined access information. Due to the fact that the specific host is switched by the network-side equipment when the UE is switched among 3GPPs, signaling overheads are reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for bearer switching. Background technique [0002] 3GPP (3rd Generation Partnership Project, third-generation mobile communication standardization organization) access refers to a wireless access network formed by using the access technology defined by the international standardization organization 3GPP. 3GPP TS23.401 introduces in detail the handover of UE (user equipment) between different 3GPP accesses [0003] WLAN (Wireless Local Area Network, Wireless Local Area Network) access can be connected to EPS (Evolved Packet System, Evolved Packet System) through S2a, S2b, and S2c interfaces. Different interfaces use different mobility management protocols, so IP (Internet Protocol , Internet Protocol) streams are moved to WLAN access in different ways. For detailed IP stream migration process, please refer to 3GPP TS23.402. ...
