Embodiment Construction

[0040] An embodiment of the present invention provides a bearer processing method. After the UE switches from GERAN / UTRAN to E-UTRAN, and there is a PDN connection without a default bearer, modify the existing UE-initiated PDN connection process or UE-initiated resource In the allocation process, a default bearer is established for a PDN connection without a default bearer.

[0041] Such as figure 1 As shown, it is a flow chart of a bearer processing method according to an embodiment of the present invention, which specifically includes the following steps:

[0042] Step S101, receiving default bearer establishment request information sent by UE.

[0043] After the UE is handed over from GERAN / UTRAN to E-UTRAN, when the mobility management element on the network side finds that there is a PDN connection without a default bearer, the mobility management element sends an indication The default bearer is established for the PDN connection of the provincial bearer. or,

Abstract

The embodiment of the invention discloses a method, a system and a device of load bearing processing. The method of load bearing processing is used for establishing default load bearing for PDN connection without default load bearing after GERAN / UTRAN is switched to E-UTRAN. The method of load bearing processing has the following steps: the default load bearing establishment request information sent by UE is received, and default load bearing is established for the PDN connection without default load bearing according to the default load bearing establishment request information. The embodiment of the invention realizes the purpose of establishing the default load bearing for the PDN connection without default load bearing after UE is switched to E-UTRAN network from GERAN / UTRAN network, and guarantees that the PDN connection established on the GERAN / UTRAN side continuously keeps connection and can be continuously used in the E-UTRAN network.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of network communication, and in particular, to a bearer processing method, system and device. Background technique [0002] When UE (User Equipment, terminal) is within the coverage of E-UTARN (Evolved Universal MobileTelecommunications System Territorial Radio Access Network, Evolved Universal Mobile Telecommunications System Territorial Radio Access Network), each PDN (Packet DataNetwork, Packet data network) connections must have a default bearer, but when the UE is in GERAN (Global System for Mobile Communications Enhanced Datarates for GlobalEvolution Radio Access Network, Global System for Mobile Communications Enhanced Data Rates for Global Evolution Radio Access Network) / UTRAN( When within the coverage of the Universal Mobile Telecommunications System Territorial Radio Access Network (Universal Mobile Telecommunications System Territorial Radio Access Network), there is no ...
