Problems solved by technology

[0008] When the UE initiates a service call or the network side pages a certain UE, the UE residing in the Macro Cell will establish an RRC connection and all service bearers on the Macro Cell, which will inevitably increase the network load. Under the coverage of the Local Cell, the network side will then trigger the handover from the Macro cell to the Local cell. For the traditional X2 handover process, there may be mobility such as RRC connection interruption, handover message loss, or UE to target access point synchronization failure. question
[0009] To sum up, in the current E-UTRAN network architecture, when the UE initiates a service call or the network side pages a certain UE, the RRC (Radio Resource Control, Radio Resource Control) connection is interrupted, the handover message is lost, or the UE reaches the target. Mobility problems such as point synchronization failures occur frequently

example 1

[0179] Example 1. When the UE initiates service establishment, such as Figure 13 Shown:

[0180] 1. The UE sends an RRC Connection Setup Request (RRC Connection Setup Request) message to the Macro eNB;

[0181] 2. The Macro eNB sends an RRC Connection Setup (RRC Connection Setup) message to the UE;

[0182] 3. The UE sends an RRC Connection Setup Complete (RRC Connection Setup Complete) message to the Macro eNB;

[0183] 4. Macro eNB sends initial UE message (Initial UE Message) to MME;

[0184] 5. The MME returns an Initial Context Setup Request (Initial Context Setup Request) message to the Macro eNB;

[0185] In steps 1-5, the UE establishes the RRC signaling connection and the S1 signaling connection at the macro eNB, and completes the establishment of the signaling connection.

[0186] 6. According to the E-RAB information in the initial context establishment request message, the Macro eNB decides to separate the control plane and the user plane in combination with t...

example 2

[0197] Example 2: After receiving the E-RAB modification message from the core network, the Macro eNB can modify the DRB bearer established in the Local, such as Figure 14 Shown:

[0198] 1. The Serving GW sends an Update Bearer Request (Update Bearer Request) message to the MME;

[0199] 2. The MME sends an E-RAB Modify Bearer Request (E-RAB Modify Bearer Request) message to the Macro eNB;

[0200] 3. After receiving the E-RAB modification message from the core network, the Macro eNB sends a bearer modification request (Modify Request) message to the Local eNB, which includes updated QOS and other information;

[0201] 4. After the Local eNB receives this message, it will update the corresponding parameters such as RLC / MAC / PHY for the corresponding DRB bearer working in the Local eNB according to the relevant information, and return the bearer modification response (Modify Response) message, which contains the updated RLC / MAC / PHY parameters, etc.;

[0202] 5. After receiv...

example 3

[0208] Example 3: The Macro eNB and the Local eNB have established the initial context of the UE. If the Macro receives the E-RAB establishment or deletion message from the core network, it can reconfigure the local DRB bearer (that is, add or delete some DRB bearers) ,Such as Figure 15 Shown:

[0209] 1. The Serving GW sends a Create Bearer Request message to the MME;

[0210] 2. The MME sends an E-RAB Setup (E-RAB Setup Request) message to the Macro eNB;

[0211] 3. After receiving the E-RAB establishment message from the core network, the Macro eNB sends a bearer modification request (Modify Request) message to the Local eNB, which contains information such as the QOS of the bearer to be established;

[0212] 4. After the Local eNB receives this message, it will establish the corresponding RLC / MAC / PHY parameters for the DRB bearer according to the relevant information, and return the bearer modification response (Modify Response) message, which contains the updated RLC / M...

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method, system and equipment for establishing services, and aims to solve the problem that in an E-UTRAN structure in the prior art, when UE makes a service call or receives paging from a network side, poor mobility frequently occurs. The method includes the steps that after the UE makes the service call or receives the paging from the network side, it is determined that RRC connection is established on a macro base station; all DRBs of a control plane are kept on the macro base station, and part or all of layers corresponding to part or all of DRBs on a user plane are switched to be on at least one local base station. When the UE makes the service call or receives the paging from the network side in the E-UTRAN architecture, the number of times of poor mobility such as RRC connection interrupt, loss of switchover information and synchronous failures from the UE to target access points is 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 service establishment. Background technique [0002] Such as Figure 1A As shown in the schematic diagram of the network architecture of E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network), E-UTRAN is composed of eNB (evolved base station). [0003] The MME (Mobility Management Entity, Mobility Management Entity) is connected to the eNB through the S1-MME interface; the eNB completes the access network function and communicates with the UE (User Equipment) through the air interface. For each UE attached to the network, there is an MME providing services for it, and the MME is called the serving MME of the UE. The S1-MME interface provides UE with control plane services, including mobility management and DRB management functions. [0004] The S-GW (Serving GW, s...
