Embodiment 1

[0025] refer to figure 1 , shows a flow chart of steps of a method for notifying bearer information according to Embodiment 1 of the present application.

[0026] The bearer information notification method in this embodiment includes the following steps:

[0027] Step S102: The EPC (evolved packet core network) notifies the eNB (evolved base station) of the default bearer of the UE (user equipment) corresponding to the E-RAB message by sending an E-RAB (enhanced radio access bearer) message to the eNB (evolved base station) ; Wherein, the E-RAB message carries information indicating the default bearer of the UE.

[0028] In the prior art, the EPC knows which of the UE's bearers is the default bearer, but the base station does not, which leads to communication accidents in some cases. For example, the EPC side UE handover process requires that the UE's default bearer must be switched If successful, the original default bearer is established in the target cell; otherwise, the ...

Embodiment 2

[0032] refer to figure 2 , shows a flow chart of steps of a method for notifying bearer information according to Embodiment 2 of the present application.

[0033] The bearer information notification method in this embodiment includes the following steps:

[0034] Step S202: carrying information for indicating the default bearer of the corresponding UE in the E-RAB message.

[0035]Among them, the E-RAB message can be any message related to UE bearer, including: E-RAB SETUP REQUEST (E-RAB establishment request message), E-RAB SETUP RESPONSE (E-RAB establishment request response message), E-RAB MODIFY REQUEST (E-RAB modification request message), E-RAB MODIFY RESPONSE (E-RAB modification request response message), INITIAL CONTEXT SETUP REQUEST (initial context establishment request message), INITIAL CONTEXT SETUP RESPONSE (initial context establishment response message) one or more of . Of course, it is not limited to this, and other appropriate messages related to the UE be...

Embodiment 3

[0041] refer to image 3 , shows a flow chart of steps of a method for notifying bearer information according to Embodiment 3 of the present application.

[0042] In this embodiment, the INITIAL CONTEXT SETUP REQUEST message in the 3GPP TS 36.413 protocol is taken as an example to illustrate the bearer information notification method of the present application. However, those skilled in the art should understand that other similar scenarios and / or similar E-RAB messages can refer to this embodiment to implement corresponding bearer information notification.

[0043] The bearer information notification method in this embodiment includes the following steps:

[0044] Step S302: Add an IE (information element / information element) of UE default bearer identifier in the INITIAL CONTEXT SETUP REQUEST message.

[0045] In the prior art, the INITIAL CONTEXT SETUP REQUEST signaling in the 3GPP TS 36.413 protocol carries parameters for establishing a bearer, and its IE is shown in Tab...

Abstract

The invention provides a method and a device for notifying bearer information. The method for notifying bearer information includes that an evoluted packet core network EPC sends enhanced radio access bearer (E-RAB) information to an eNB of an evoluted base station so that a defaulted bearer of user equipment UE corresponding to the E-RAB information can be notified to the eNB, wherein the E-RAB information carries information indicating the defaulted bearer of the UE. By the method and the device for notifying bearer information, communication accidents caused by the fact that the base station cannot acquire the defaulted bearer of the UE are effectively avoided, and using experience of users is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, in particular to a method and device for notifying bearer information of an E-RAB (Enhanced-Radio Access Bearer, enhanced radio access bearer). Background technique [0002] In 3GPP, RAB (Radio Access Bearer, radio access bearer) provides users with data connection capabilities from the core network to UE (User Equipment, user equipment). In LTE, RAB is renamed E-RAB. The E-RAB of LTE starts from the S-GW (serving gateway) and ends at the UE. It is composed of S1-U bearer and DRB (Data Radio Bearer, data radio bearer) in series. The service data entering the LTE system is mainly carried out through E-RAB transmission. In order to manage E-RAB, control signaling between corresponding signaling connection transmission network elements is required in the LTE system to complete, including the establishment, modification and release of E-RAB. [0003] For a UE, especially after es...
