Problems solved by technology

When a handover between eNBs within the MME occurs, the EPS bearer shared AMBR information needs to be passed from the source eNB to the target eNB through the X2 interface; when an inter-MME handover occurs, the EPS bearer shared AMBR information needs to be passed from the MME to the target eNB through the S1 interface Target eNB, currently there is no effective method to transfer AMBR sharing control information when handover occurs

Embodiment 1

[0056] Figure 5 It is a flow chart of the control method for multi-bearer sharing AMBR when intra-MME handover occurs according to the present invention.

[0057] In this embodiment, it is an intra-MME handover process. When the source eNB sends a message to the target eNB, all bearers sharing the same AMBR carry the same AMBR access point name to indicate the sharing relationship of these bearers to the AMBR.

[0058] Such as Figure 5 As shown, the method includes the following steps:

[0059] 501. The source eNB makes a handover decision according to the measurement report of the UE, and decides to initiate handover between eNBs;

[0060] 502. The source eNB initiates a handover request message to the target eNB. The message contains the bearer information to be established, and also needs to bring the bearer sharing AMBR relationship to be established to the target eNB; for bearers sharing the same AMBR, all carry The access point name of the same AMBR thus indicates t...

Embodiment 2

[0071] Figure 6 It is a flow chart of the control method for multi-bearer sharing AMBR when an inter-MME handover occurs according to the present invention.

[0072] In this embodiment, it is an inter-MME handover process. When the MME sends a message to the target eNB, all bearers sharing the same AMBR carry the same AMBR access point name to indicate the sharing relationship of these bearers to the AMBR.

[0073] Such as Figure 6 As shown, the method includes the following steps:

[0074] 601. The source eNB makes a handover decision according to the measurement report of the UE, and decides to initiate handover between eNBs;

[0075] 602. The source eNB sends a handover request message to the MME;

[0076] 603. The MME sends a handover request message to the target eNB. The message contains the bearer information to be established, and also needs to bring the bearer sharing AMBR relationship to be established to the target eNB; for bearers sharing the same AMBR, they a...

Abstract

The invention aims to provide a multi-bearing shared AMBR switching control method, which comprises the following steps: step one, source base station initiates switching, and sends a switching request message carrying bearing establishing information and bearing shared AMBR relation information; step two, target base station obtains the bearing establishing information and the bearing shared AMBR relation information, then establishing a shared AMBR bearing. The beneficial effect of the invention is that: it can transmit the relation of EPS bearing shared AMBR from source base station through X2 interface, or from network side MME through S1-MME interface, to target base station, can enable the target base station to obtain AMBR shared control information, and realize the control to multi-bearing shared AMBR.

Description

technical field [0001] The present invention relates to the field of mobile communication, and more specifically, relates to a multi-bearer sharing AMBR handover control method. Background technique [0002] With the sudden emergence of World Interoperability for Microwave Access (Wimax), the third-generation mobile communication system must improve its network performance and reduce network construction and operation in order to maintain its strong competitiveness in the field of mobile communication. cost. [0003] Therefore, the standardization working group of 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) is currently working on the research on PS Core (Packet SwitchCore, packet switching core network) and UTRAN (Universal Mobile Telecommunication System Radio Access Network, global mobile communication system The evolution of the wireless access network), this research topic is called System Architecture Evolution (SAE for short) and t...
