Embodiment Construction

[0207] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0208] like figure 1 As shown, the embodiment of the present invention provides a data transmission method, the method is executed by a mobility management network element, including:

[0209] 101. The mobility management network element acquires an indication of whether to establish a default bearer for the user equipment.

[0210] The mobility management network element may be a mobility management entity (Mobility Management Entity, MME), or a serving GPRS supp...

Abstract

The present invention provides a data transmission method and apparatus, which relate to the technical field of communications and can save network resources. The method comprises: a mobility management entity obtaining an indicator about whether to establish a default bearer for user equipment; when determining according to the indicator about whether to establish a default bearer for user equipment that the default bearer is not established, the mobility management entity transmitting to a wireless access network an indicator about non-establishment of the default bearer; and the mobility management entity realizing data transmission with the user equipment through NAS signaling when the default bearer is not established.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a data transmission method and device. Background technique [0002] In the evolved packet network (EPS, Evolved Packet System), when the user equipment (User Equipment, UE) completes the network attachment process, the network side will establish a default bearer for the user equipment, and the default bearer can be used for data transmission, and It can only be deleted when the UE logs off from the network side. [0003] However, when the UE needs to send data based on non-network interconnection protocol (Internet Protocol, IP) link services or data of small data volume services, it is not necessary to use the default bearer for data transmission, resulting in idle default bearer, wasteful network resources. Contents of the invention [0004] The invention provides a data transmission method and device, which can save network resources. [0005] In order to...
