Embodiment 1

[0036] Embodiment 1 of the present invention provides a method for accessing a network. The steps of the method are as follows figure 1 As shown, it specifically includes the following steps:

[0037] Step 101, establishing a relay channel between the served terminal and the relay terminal.

[0038] The served terminal refers to a terminal whose channel quality is lower than a first set value, and the relay terminal refers to a terminal whose channel quality is higher than a second set value.

[0039] When the served terminal needs to access the network side, a process of relay discovery and negotiation is performed with the relay terminal, and a relay channel is established.

[0040] The relay channel can be established based on short-distance communication technology, such as 802.11x WLAN protocol, and of course, the relay channel can also be established through long-distance communication technology, such as CDMA, TD-SCDMA, LTE and so on.

[0041] Step 102, the served ter...

Embodiment 2

[0080] In the terminal provided by Embodiment 2 of the present invention, the channel quality of the terminal is lower than the first set value, and the structural diagram of the terminal is as follows image 3 shown, including:

[0081] The relay channel establishment module 11 is used to establish a relay channel with a relay terminal whose channel quality is higher than the second set value; the first sending module 12 is used to send an access indication to the relay terminal through the relay channel, The relay terminal is required to connect the terminal whose channel quality is lower than the first set value to the network side; the first receiving module 13 is used to establish a communication tunnel with the network side after the relay terminal receives the access instruction The random access success indication message sent later; the second sending module 14 is configured to send the radio resource control RRC connection to the relay terminal through the relay chan...

Embodiment 3

[0090] In the terminal provided by Embodiment 3 of the present invention, the channel quality of the terminal is higher than the second set value, and the structural diagram of the terminal is as follows Figure 4 shown, including:

[0091] The relay channel establishment module 21 is used to establish a relay channel with the served terminal whose channel quality is lower than the first set value;

[0092] The first receiving module 22 is configured to receive an access indication sent by the service terminal through the relay channel, and the access indication requires that the terminal whose channel quality is higher than the second set value will be accessed by the service terminal to the network side;

[0093] The first sending module 23 is configured to establish a communication tunnel between itself and the network side after receiving the access indication, and send a random access success indication message to the served terminal through the relay channel.

[0094] T...

Abstract

The embodiment of the invention provides a method, a terminal and a system for accessing the network. In the method, a relay channel is established between a served terminal in which the information channel quality is lower than a first set value and a relay terminal in which the information channel quality is higher than a second set value, and the relay terminal with the higher information channel quality is used for connecting the served terminal with the lower channel information quality with the Internet. Compared with the scheme that the served terminal in which the channel quality is lower than the first set value is directly connected with the network side in the prior art, the data transmission rate between the served terminal and the relay terminal can be guaranteed by the relay channel, and because the information channel quality of the relay terminal is better, the data transmission rate between the relay terminal and the network side is guaranteed, so that data can be transmitted at a high data transmission rate between the served terminal and the network side, and the business with high requirement on the data transmission rate can be successfully carried out.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, terminal and system for accessing a network. Background technique [0002] With the development of wireless communication technology, in order to ensure the smooth execution of various services, various services have put forward higher and higher requirements for data transmission rates. [0003] In order to meet the data transmission rate requirements of various services, in the long term evolution (LTE, long term evolution) system, for terminals that are closer to the base station, due to the ideal channel quality of the terminal, the stability of data transmission is better, in order to improve For the data transmission rate, a multi-input-multi-output (MIMO, multi-input-output) technology or a high-order modulation and coding method may be used to increase the data transmission rate, so as to meet the data transmission rate requirements of the...
