Embodiment 1

[0081] Such as image 3 Shown, this embodiment one comprises the following steps:

[0082] In step S301, the user terminal 1UE initiates a radio bearer establishment request command to the primary cell 2.

[0083] Step S302, such as figure 1 The primary cell 2 may choose to forward the first bearer establishment request to one or more secondary cells 3 according to the load data of the secondary cells 3 . In this step, the primary cell 2 selects a secondary cell 3 to initiate a bearer establishment request according to the load status of the existing secondary cells 3 . The message carries ID information of the UE, and the first bearer establishment request may be a radio bearer establishment request.

[0084] Step S303, after the auxiliary cell 3 receives the bearer establishment request from the primary cell 2, the auxiliary cell 3 sends a second bearer establishment request to the core network 4, and the second bearer establishment request may be an E-RAB bearer establis...

Embodiment 2

[0090] Such as image 3 As shown, since in the embodiment of the present invention, the process of establishing the E-RAB connection between the auxiliary cell 3 and the core network 4 and the establishment of the radio bearer between the auxiliary cell 3 and the user terminal 2UE can be a parallel process, therefore, the present invention can follow the following steps Implement the present invention, the concrete steps of embodiment two are as follows:

[0091] In step S301, the user terminal 1UE initiates a radio bearer establishment request command to the primary cell 2.

[0092] Step S302, such as figure 1 The primary cell 2 may choose to forward the first bearer establishment request to one or more secondary cells 3 according to the load data of the secondary cells 3 . In this step, the primary cell 2 selects a secondary cell 3 to initiate a bearer establishment request according to the load status of the existing secondary cells 3 . The message carries ID information...

Embodiment 3

[0099] Such as image 3As shown, since in the embodiment of the present invention, the process of establishing the E-RAB connection between the auxiliary cell 3 and the core network 4 and the establishment of the radio bearer between the auxiliary cell 3 and the user terminal 2UE can be a parallel process, therefore, the present invention can follow the following steps Implement the present invention, the concrete steps of embodiment three are as follows:

[0100] In step S301, the user terminal 1UE initiates a radio bearer establishment request command to the primary cell 2.

[0101] Step S302, such as figure 1 The primary cell 2 may choose to forward the first bearer establishment request to one or more secondary cells 3 according to the load data of the secondary cells 3 . In this step, the primary cell 2 selects a secondary cell 3 to initiate a bearer establishment request according to the load status of the existing secondary cells 3 . The message carries ID informatio...

Abstract

The invention provides a method for establishing a service bearer. The method comprises the following steps: a user terminal transmits one or more first bearer establishing requests; a primary cell selects to transmit the first bearer establishing requests to one or more auxiliary cells according to the bearer data of the auxiliary cell; the auxiliary cell acquires the bearer data by transmitting a second bearer establishing request to a core network; and the user terminal establishes a service bearer with the auxiliary cell according to the first bearer establishing request to acquire the bearer data. The invention also provides a system for establishing the service bearer. According to the method and system provided by the invention, the problem that multiple cells can not serve one user terminal in a long term evolution (LTE) system in the prior art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for establishing a service bearer. Background technique [0002] In a Long Term Evolution-Advanced (LTE for short) system, only one cell serves a certain user terminal UE at a time. When service bearers are established between the cell and the user terminal UE, how to allocate different bearers to different The auxiliary cell is the problem to be solved. [0003] There is currently no effective solution to the problem that multiple cells cannot serve one user terminal in the long-term evolution LTE system of the prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a method and system for establishing a service bearer, so as to solve the problem that multiple cells cannot serve a user terminal in the long-term evolution LTE system of the prior art. [0005] In order to achieve the above object, according to...
