Problems solved by technology

However, different DCHs or different FACHs correspond to different time requirements, and the time information provided by RNC only indicates the unique CFN time, which cannot meet the different time requirements of different DCHs or FACHs, so the sending time of each channel cannot be controlled separately
[0007] It can be seen that the existing data transmission control method cannot guarantee the time requirement of the wireless transmission channel during data transmission

Embodiment 1

[0067] In this embodiment, the time reference information is intermediate information indicating the sending time, that is, the time offset of the CFN of each wireless transmission channel relative to the RNC internal time reference and the internal time reference of the RNC. The base station can calculate the corresponding wireless transmission time through the intermediate information The send time of the transport channel.

[0068] figure 2 It is a structural diagram of a data transmission control system in mobile communication according to Embodiment 1 of the present invention. Such as figure 2 As shown, the data transmission control system in the mobile communication of the present invention includes: RNC 201 and base station 202 .

[0069] Wherein, the RNC 201 includes: a main control unit 211 , a time reference unit 212 and an offset calculation unit 213 .

[0070] Deviation calculation unit 213 stores information related to pre-established MBMS services, including...

Embodiment 2

[0113] In this embodiment, the time reference information is information directly indicating the sending time, that is, the CFN of each wireless transmission channel.

[0114] Figure 4 It is a structural diagram of a data transmission control system in mobile communication according to Embodiment 2 of the present invention. Such as Figure 4 As shown, the data transmission control system in the mobile communication of the present invention includes: RNC 401 and base station 402 .

[0115] Wherein, the RNC 401 includes: a main control unit 411 , a time reference unit 412 and a channel parameter unit 413 .

[0116] The channel parameter unit 413 stores the relevant information of the pre-established MBMS service, including information such as the MBMS service identifier and the wireless transmission channel in the service path; when the wireless transmission channel is established or reconfigured, it obtains the CFN of the channel, namely CFNi; The relevant information of th...

Abstract

The invention discloses a data transfer and control method in mobile communication, which builds an operation route in advance; the invention comprises the following steps: a network control device decides time reference information for a wireless transfer channel, and then the operation data from network side and the decided time reference information are transmitted to a base station through a share channel; the base station transmits the operation data from the network control device to user device through the wireless transfer channel included in the pre-set operation route according to the received time reference information. The invention also discloses a data transfer and control system in mobile communication. The invention provides the interior maintained time reference information of each wireless transfer channel to the base station; and then the base station transmits the operation data to the user device respectively through each wireless transfer channel according to thetime reference information of each wireless transfer channel; in this way, the invention can guarantee the time requirement for the wireless transfer channel in the process of data transfer.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a data transmission control method and a data transmission control system in mobile communication. Background technique [0002] Multimedia Broadcast Multicast Service (MBMS) is a point-to-multipoint unidirectional service, that is, a service in which one data source sends service data to multiple receivers. When the MBMS service is implemented based on the wireless interface, service data is transmitted through a downlink wireless transmission channel between the base station and user equipment (User Equipment, UE), and each serving cell or each UE occupies a downlink wireless transmission channel. Wherein, the downlink wireless transmission channel may be a dedicated channel (Dedicated Channel, DCH) or a forward access channel (Forward Access Channel, FACH). [0003] With the mobile communication system as the third generation (3 rd Generation, 3G) mobile communication syst...
