Problems solved by technology

However, even so, in step 206, the RNC obtains the terminal capability information through the wireless connection establishment complete message. For a terminal configured in the enhanced CELL-FACH state, since there is no signaling process dedicated to the control plane of the Iub interface, the RNC cannot send the terminal The capability information is transmitted to the base station, and the base station can only use the minimum HSDPA and / or HSDPA capability to schedule the terminal
[0029] From the above analysis, it can be seen that in the HSPA enhanced system, when the terminal is configured from the idle mode to the CELL-FACH state, there is a problem that the terminal capability information cannot be transmitted to the base station, so that the base station can only use the minimum capability level for the terminal. problem with scheduling

Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0065] In the enhanced HSPA system, terminals in the CELL-FACH state are allowed to use the E-DCH to upload data. E-DCH is a shared channel, and the E-DCH resources are controlled by the HSUPA scheduler on the base station side. If the terminal does not receive the E-DCH resources allocated by the base station, it needs to send uplink scheduling information to the base station through the E-RUCCH, and the base station then Allocate E-DCH resources for the terminal according to the received uplink scheduling information.

[0066] The present invention proposes a method for transmitting terminal capability information in an HSPA enhanced system, when the terminal is configured from the idle mode to the CELL-FACH state, including the following two met...

Abstract

The invention discloses a method and a system for terminal capacity information transmission. The method is applied to the condition of a terminal configured to a cell forward access channel and comprises the steps: a base station receives upstream scheduling information transmitted by the terminal through an upstream reinforcing random access control channel E-RUCCH, and the upstream scheduling information contains the terminal capability information; the base station decodes the upstream scheduling information according to a set E-RUCCH decoding format, and the terminal capacity information is obtained. The invention realizes the scheme that the terminal capacity information is transmitted to the base station in a high-speed packet access reinforcing system in a state that the terminal is configured to the cell forward access channel.

Description

technical field [0001] The present invention relates to information transmission technology, in particular to a transmission method, system, terminal, base station and wireless network controller of terminal capability information. Background technique [0002] The terminal capability information includes high speed uplink packet access (HSUPA, High Speed ​​Uplink Packet Access) capability level information and high speed downlink packet access (HSPDA, High Speed ​​Downlink Packet Access) capability level information of the terminal. Specifically, the HSUPA capability level information refers to the maximum transmission rate, maximum number of time slots, modulation capability, and maximum number of supported carriers of an enhanced dedicated channel (E-DCH, Enhanced Dedicated Channel) that the terminal can support; similarly, HSDPA capability level information refers to information such as the maximum transmission rate, maximum number of time slots, modulation capability, a...
