Problems solved by technology

[0006] In the process of implementing the embodiments of the present invention, the inventors found that the prior art has at least the following technical problems: in the prior art, when the target MME / SGSN participates in establishing data forwarding bearers, it will establish data forwarding tunnels for all bearers. When some bearers do not need data forwarding, the target MME / SGSN will also establish a data forwarding tunnel for them, resulting in waste of resources

Embodiment Construction

[0071] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0072] The processing solution for handover data forwarding provided by the embodiment of the present invention can be given by the network element in the source system (such as source MME, source base station, source RNC or source SGSN) when the terminal is switched between different systems. For the suggestion of data forwarding by the bearer, the network element on the target side determines the bearer that needs data forwarding according to the above suggestions, referred to as the data forwarding bearer. In addition, the network element on the target side can give suggestions according to multiple parameters such as actual network conditions or directly After confirming, the finally determined bearer information requiring data forwarding is returned to the source base station or the source radio network contr...

Abstract

A method, an apparatus, and a system for data forwarding processing during handover are disclosed. The method includes: receiving data forwarding bearer information wherein the data forwarding bearer information suggests whether a bearer is subject to data forwarding; determining a bearer subj ect to data forwarding according to the data forwarding bearer information; and returning bearer information about the bearer subject to data forwarding to perform data forwarding. The apparatus includes a receiving module, a processing module, and a sending module. The corresponding system for data forwarding processing during handover is also disclosed. The method, apparatus, and system for data forwarding processing during handover under the present invention avoid data forwarding on unnecessary bearers and reduce the waste of resources.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a handover data forwarding processing method, device and system. Background technique [0002] In the Third Generation Partnership Project (Third Generation Partnership Project, hereinafter referred to as: 3GPP), various vendors are actively researching Long Term Evolved (hereinafter referred to as: LTE) / System Architecture Evolved (hereinafter referred to as: SAE), the purpose of LTE / SAE is to provide a low-cost network that can reduce delay, increase user data rate, improve system capacity and coverage, use PS domain services, and bearer network is IP network. [0003] The LTE / SAE network architecture includes the following components. The function of the MME is to include the mobility management context of the UE, such as user identity, mobility management status, location information, etc. ) signaling, responsible for the security of NAS signaling, etc. ...
