Problems solved by technology

[0006] The V2X method is used to support road safety applications. Usually, it is required that the sending vehicle receives the road safety message from the upper layer and the MAC (Medium Access Control) layer of the receiving vehicle submits the road safety message to the higher layer. It is greater than 100ms, and the shortcoming of the existing technology is that: the total delay of information interaction is 160ms for the V2X service realized based on the existing eMBMS technology, which cannot meet the delay requirements of supporting road safety applications
[0007] In fact, this problem exists not only in V2X services, but also in other similar environments or applications, that is, the existing information transmission based on eMBMS technology cannot meet the delay requirements of some services

Embodiment A1

[0267] Embodiment A1: Establishing an MBSFN data channel

[0268] In the embodiment, the most common resource-bandwidth will be taken as an example for illustration. Then eNB1 (Source eNB) determines the level of bandwidth required to exchange user plane data according to the number of UEs participating in V2X in the data source cell of each MBSFN area under it and the load information, and requests to establish an X2 user plane with eNB2 (Target eNB) data channel. Figure 12 Schematic diagram of the implementation process of establishing the signaling interaction process for the MBSFN data transmission channel of the X2 interface. As shown in the figure, the basic signaling interaction process may include:

[0269] Step 1201, eNB1 sends an MBSFN data channel establishment request to eNB2;

[0270]Step 1202, eNB2 sends an MBSFN data channel establishment response to eNB1.

[0271] In specific implementation, one data channel establishment message may be used to establish on...

Embodiment A2

[0326] Example A2: Update data channel configuration

[0327] In the embodiment, the most common resource-bandwidth will be taken as an example for illustration. The situation described in this embodiment is as follows: when the UE quantity information, load information, and cell list contained in the MBSFN area in the data source cell of each MBSFN area change, the configuration of the corresponding data channel needs to be updated. Figure 13 Schematic diagram of the implementation flow for the configuration update process of the MBSFN data transmission channel on the X2 interface. As shown in the figure, the basic signaling interaction process may include:

[0328] Step 1301, eNB1 sends an MBSFN data channel update request to eNB2;

[0329] Step 1302, eNB2 sends an MBSFN data path update confirmation to eNB1.

[0330] In specific implementation, one data channel update message may be used to update only one data channel, or one data channel update message may be used to s...

Embodiment A3

[0370] Example A3: Deactivate / Release Data Channel

[0371] The situation described in this embodiment is as follows: if the Source eNB decides that MBSFN transmission is no longer needed, it should request the Target eNB to release the reserved resources and release the user plane data channel. Figure 14 It is a schematic diagram of the implementation flow of the deactivation / release process of the MBSFN data transmission channel on the X2 interface. As shown in the figure, the basic signaling interaction process may include:

[0372]Step 1401, eNB1 sends an MBSFN data channel deactivation / release message to eNB2.

[0373] During implementation, multiple channels can be deactivated or released in the data channel deactivation or release message, and the content can be as follows:

[0374] Deactivate / release the eNB ID of the X2MBSFN channel,

[0375] Deactivated / released user plane data channel ID or ID list.

[0376] 2. Implementation of information transmission between ...

Abstract

The invention discloses an information reporting / receiving method and device and a bearer establishing method and device. The information receiving method is characterized by comprising that terminal equipment sends indication information to an access network node, wherein the indication information is used for indicating that information to be reported by the terminal equipment is information to be sent on time and frequency resources corresponding to a multicast broadcast single frequency network area; the access network node requests network-side equipment to establish a service bearer for the information to be reported by the terminal equipment; the network-side equipment establishes a service bearer, wherein the service bearer comprises a wireless bearer used by the terminal equipment for reporting information to the access network node and notifying configuration information of the service bearer established by the access network node; and the access network node configures a wireless bearer for the information to be reported of the terminal equipment according to the configuration information, notifies the terminal equipment to report the information on the configured wireless bearer, and receives the information reported by the terminal equipment on the configured wireless bearer. According to the invention, the terminal equipment receives a notification; and information is collected, and the information is reported on the wireless bearer according to the configuration information. By adopting the method and device disclosed by the invention, requirements of services having specific requirements for time delay can be met.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for information reporting, receiving, and bearer establishment. Background technique [0002] The existing mobile communication is mainly the communication between people. With the miniaturization and intelligence of hardware equipment, the future mobile communication will be more high-speed connection applications between "people and things" and "things and things". Taking MTC (Machine Type Communication) business as an example, MTC has a wide range of applications, such as mobile medical care, Internet of Vehicles, smart home, industrial control, and environmental monitoring, which will promote the explosive growth of MTC system applications, and a large number of devices will connect Connect to the network, realize the true "Internet of Everything", and bring infinite vitality to mobile communication. At the same time, the wide range of MTC ...
