Embodiment 1

[0049] This embodiment describes the process in which base station 1 establishes a user data bearer on base station 2, MME sets the aggregate maximum rate of UE for the base station, and configures the maximum aggregate rate of UE through the X2 interface between base stations, as shown in image 3 shown. Among them: base station 1 is the base station where the user's serving cell is located, that is, the base station MeNB where the user's main cell is located, base station 2 is SeNB, which provides data bearer for the user, base station 2 receives downlink data from the serving gateway or base station 1 and sends it to the UE, base station 1 There is an X2 interface with base station 2. This embodiment omits the signaling interaction process between the base station and the UE, and between the MME and the gateway. image 3 The illustrated process may include the following steps:

[0050] Step 301: MME sends an "initial context establishment request" message to base station ...

Embodiment 2

[0075]This embodiment describes a method for base station 1 and base station 2 to coordinate and adjust the aggregation rate. The base station 1 is the base station MeNB where the serving cell of the user is located, and the base station 2 is the SeNB that provides data bearer for the user. Base station 2 receives downlink data from the gateway or base station 1 and sends it to the UE. There is an X2 interface between base station 1 and base station 2. In this embodiment, the process of signaling interaction between the base station and the UE, and between the MME and the gateway is omitted.

[0076] This embodiment provides two different implementation methods, respectively as Figure 4 Method 1 and Method 2 in the above.

[0077] Figure 4 The shown method one may include the following steps:

[0078] Step 401a: Base station 2 sends an "aggregation rate report" message to base station 1.

[0079] In this message, the identification information of the UE on the X2 interf...

Embodiment 3

[0104] This embodiment describes that the main base station MeNB determines the AMBR used by the MeNB and the SeNB according to the QCI. Figure 5 The shown method may include the following situations. In the following description, base station 1 may be a MeNB and base station 2 may be an SeNB; or base station 1 may be a SeNB and base station 2 may be a MeNB.

[0105] 1. Allocate the same QCI to the non-GBR on the MeNB and the SeNB. At this time, the MeNB allocates the same AMBR to the MeNB and the SeNB, and the sum of the two AMBRs is equal to the UE-ABMR. For example, if UE-AMBR=100, then the AMBRs of MeNB and SeNB are 50 respectively.

[0106] 2. The QCI of the non-GBR bearer established on base station 1 is 5, and the QCI of the non-GBR bearer established on base station 2 is 7. At this time, MeNB allocates the same AMBR to base station 1 and base station 2, the sum of the two AMBRs Equal to UE-ABMR. For example, if UE-AMBR=100, then the AMBRs of MeNB and SeNB are 50 res...

Abstract

The present invention provides a method for configuring the aggregated maximum rate of the UE, including: A. the master base station MeNB obtains the aggregated maximum rate UE-AMBR of the UE; B. the master base station MeNB obtains information for configuring the aggregated maximum rate of the slave base station SeNB , and configure the aggregated maximum rate used by the SeNB according to the information. The present application also provides a method for coordinating the aggregation rate of non-GBR services among base stations, and a base station corresponding to the above two methods. By applying this application, when non-GBR services are established in different base stations, the maximum value of the aggregation rate used by each base station can be allocated, and the limited bearer bandwidth can be effectively used to reduce data transmission delay.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a method for configuring the aggregated maximum rate of UE, coordinating the aggregated rate of non-GBR services and a base station. Background technique [0002] Modern mobile communication tends to provide users with high-speed multimedia services, such as figure 1 Shown is the system architecture diagram of System Architecture Evolution (SAE). in: [0003] User Equipment (UE) 101 is a terminal device for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network including macro base stations (eNodeBs / NodeBs) providing UEs with an interface to access the radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity. The ...
