Embodiment Construction

[0027] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] figure 2 It is a specific flowchart of the uplink service data transmission method in the present invention. In the process of this method, a UE in the CELL_PCH state and with a dedicated user identity, when there is an uplink service that needs to be sent and the state transitions, such as figure 2 As shown, the method includes:

[0029] Step 201: The UE performs uplink synchronization, transfers its own state to CELL_FACH, and uses its own dedicated user ID to send system information SI on the E-RUCCH, indicating that the NodeB has completed uplink synchronization and there is uplink data to be sent.

[0030] Among them, the UE directly transfers its own state to CELL_FACH, and does not need to first send cell update information to the RNC through the NodeB as i...

Abstract

The invention discloses a method for transmitting uplink business data in an HSPA + system. When UE equipped with a special user identification and in CELL_PCH state needs the transmission of uplink business data, the UE directly converts the self state into CELL_FACH and uses the special user identification of the self to transmit SI information to NodeB through an E-RUCCH channel. After receiving the SI information, the NodeB does not judge the state of UE and directly authorizes uplink channel resource for the UE; the UE utilizes the authorized uplink channel to directly transmit DCCH / DTCH data, the NodeB loads the received DCCH / DTCH data on the E-DCH FP frame of IuB port to be sent to RNC, and after receiving a first FP frame carrying DCCH / DTCH data, the RNC converts the network side RRC state of the UE to the CELL_FACH. The use of the method can realize the direct transmission of uplink data, shorten processing time delay and save signaling cost.

Description

Technical field [0001] The present invention relates to a method for sending uplink service data, in particular to a method for UE to send uplink service data in an HSPA+ system. Background technique [0002] In R4 and HSPA systems, users with inactive business data can switch to the CELL_PCH (Paging Channel) state to further save power consumption; when there is uplink and downlink data to be transmitted, the cell update process is carried out to enable users to switch to CELL_FACH (Forward Access). Channel) status, and then data transmission. [0003] In the HSPA+ system, the division of the user’s CELL_PCH state and CELL_FACH state is also reserved. At the same time, for UEs with a dedicated user ID and in the CELL_PCH state, HSPA+ supports direct data transmission (DTCH / DCCH) in the CELL_PCH state, which is An effective method to support always-on UEs. Similar to the R4 and HSPA systems, users with inactive service data can switch to the CELL_PCH state to further save power co...
