Problems solved by technology

The current problem is that when the cells participating in carrier aggregation are in different base stations (that is, when the cells participating in carrier aggregation are controlled by different base stations), multiple S1 data bearers are established for users between the SGW and the base station , the UE's non-GBR service may be established on different base stations, therefore, the current UE-AMBR cannot be used in the case where a UE has multiple S1 data bearers

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 service cell is located, that is, the base station where the user's primary cell is located, base station 2 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 and base station 2 There is an X2 interface between them. 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 1 . ...

Embodiment 2

[0084] 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 the UE for the base station, and configures the maximum aggregate rate of the UE through the S1 interface, as shown in Figure 4 shown. Among them: base station 1 is the base station where the user serves the cell, base station 2 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, and there is no X2 interface between base station 1 and base station 2. This embodiment omits the process of signaling interaction between the base station and the UE, and between the MME and the gateway. Figure 4 The illustrated process may include the following steps:

[0085] Step 401: MME sends an "initial context establishment request" message to base station 1 .

[0086] The MME sends this message to establish context information of the UE on the base statio...

Embodiment 3

[0106] This embodiment describes the process in which base station 1 establishes a user data bearer on base station 2, and base station 1 sets the aggregated maximum rate of UE for base station 2 through the X2 interface, as shown in Figure 5 shown. Among them: base station 1 is the base station where the service cell of the user is located, base station 2 provides data bearer for the user, base station 2 receives downlink data from the serving gateway or from base station 1 and sends it to UE, and there is an X2 interface between base station 1 and base station 2. This embodiment omits the signaling interaction process between the base station and the UE, and between the MME and the gateway. Figure 5 The illustrated process may include the following steps:

[0107] Step 501: MME sends an "initial context establishment request" message to base station 1 .

[0108] The MME sends this message to establish context information of the UE on base station 1 . Before step 501, th...

Abstract

The present application discloses a method for configuring the aggregated maximum rate of the UE, including: MME sends UE-AMBR to the base station where the serving cell of the UE is located; the base station where the serving cell of the UE is located establishes a radio bearer of the UE in at least one secondary cell above; the MME sends the AMBR of the base station where the UE is located in the serving cell and the base station where the secondary cell is located to the base station where the serving cell of the UE is located; the base station where the serving cell of the UE is located sends the AMBR of the base station where the UE is located in the secondary cell to the corresponding base station. This application also discloses several other methods for configuring the UE's aggregate maximum rate. By applying the technical solution disclosed in this application, when a UE has multiple or one S1 data bearers, all non-GBR services of the UE can The sum of the rates does not exceed UE‑AMBR.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for configuring the aggregated maximum rate of UE. 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 packet data network gateway (PGW) 105 is responsible for function...
