Control method and device for special bearing establishment in default bearing establishing process

Abstract

The invention discloses a control method of special bearing building in default bearing building process, comprising that: control entity at the network side receives the special bearing building request in the default bearing building process; the control entity at the network side judges whether continuing building the special bearing according to the preset condition, if true, continuing building the special bearing; otherwise keeping the special bearing building request, till reaching all the preset conditions, continuing building the special bearing. The invention discloses a control device of special bearing building in the default bearing building process, realizing the control on the special bearing building in the in default bearing building process by the entity at the network side, ensuring successfully building the special bearing in attached flow.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control method and equipment for establishing a dedicated bearer in the process of establishing a default bearer. Background technique [0002] In the prior art, the attachment process in System Architecture Evolution (SAE) is as follows: figure 1 shown, including the following steps: [0003] Step s101, the user equipment (User Equipment, UE) sends an Attach Request (Attach Request) (IMSI or S-TMSI and old TAI, SelectedNetwork) to the evolved base station (Evolved NodeB, eNB), wherein the Attach Request (Attach Request: IMSI or S-TMSI -TMSI and old TAI, SelectedNetwork) indicates that the Attach Request (Attach Request) includes the International Mobile Subscriber Identity (IMSI) or the Temporary Mobile Subscriber Identity (SAE-Temporary Mobile Subscriber Identity, S-TMSI), and the tracking area Identification (TrackingArea Identity, old TAI), selected network...

AI Technical Summary

Problems solved by technology

However, before the radio bearer is established and the terminal receives the Attach Accept message (step s118), the terminal cannot know the IP address assigned to it by the network

If the dedicated bearer is established and sent to the terminal before the terminal knows the IP address assigned to it by the network, it will cause potential problems (for example, the terminal cannot complete the configuration of the packet filter at the application layer)
