Description

The switching method and network controller of a kind of channel status and base station and communication system

Technical field

The present invention relates to the communications field, the switching method and network controller of more particularly to a kind of channel status and base station and Communication system.

Background technology

User terminal（User Equipment, abbreviation UE）Each base station is accessed by land radio access web, realized wireless Communication.The wireless heterogeneous networks connection status of user terminal（Radio Resource Control, abbreviation RRC connection status）Can Four kinds of states are subdivided into, the present invention relates generally to dedicated connection status（CELL-DCH, Dedicated Channel）With public letter Track data state（CELL-FACH, Forward Access Channel）, abbreviation DCH states and FACH state.DCH state masters It is characterized as：UE uses DPCH, and data transmission bauds is high, is transmitted suitable for continuous, mass data, such as make a phone call, Download.FACH state is mainly characterized by：UE is using public or shared transmission channel, and message transmission rate is low, suitable for existing for a long time The small packet data transmission of line, for example signaling, instant messaging.

And in data upstream transmission, the difference of DCH states and FACH state is：DCH states can take for a long time DPCH carries out mass data transmission, and FACH state can only take DPCH in short-term.In the prior art, it is used for The channel of UE transmitting uplink datas is enhancing special uplink channel（Enhanced uplick DCH, abbreviation E-DCH）.Wireless network Network controller（Radio Network Controller, abbreviation RNC）The E-DCH resource of base station is managed for configuration.RNC gives Base station configures a total E-DCH resource pond, and any E-DCH resource in resource pool includes：One E-DCH channels and related control The information of channel processed（Main scrambler, channel logo number）, UE to the configuration information of the up transmitting capacity of the E-DCH channels, with And the configuration information of transmission bearing capacity of base station to the E-DCH channels etc..E-DCH resource includes：Special E-DCH resource and public affairs E-DCH resource altogether, network controller distribute corresponding E-DCH resource according to UE RRC connection status to UE.Distribute to FACH shapes The E-DCH resource of state is common E-DCH resource, and the E-DCH resource for distributing to DCH states is special E-DCH resource.UE and base Between standing, corresponding E-DCH channels are established according to the E-DCH resource of distribution, to realize data transfer.

With the large-scale application of intelligent terminal, UE under FACH state there is paroxysmal data business volume to increase.This The data traffic of a little bursts of traffic gradually increases, or when bursts of traffic subsequently has large-data operation, UE needs frequent Be transformed into DCH states from FACH state to obtain higher message transmission rate, after the data transfer ends, UE need again from DCH State Transferrings are to FACH state to save system resource.At this moment, the time of UE occupancy common E-DCH resource is shorter, Er Qie UE under FACH state can not carry out the business of big data quantity.And the UE of DCH states take time of special E-DCH resource compared with It is long, it can also carry out the business of big data quantity.Therefore, when the data volume of UE uplink service has greatly changed, UE needs Switched between FACH state and DCH states.

In the prior art, RNC manages E-DCH resource pond in base station by the way of distribution, realizes that UE states switch When, the channel between base station and UE is established.Specific method is as follows：

It is transmitted when UE is in FACH state using common E-DCH resource, according to certain time interval, UE is passed Defeated measuring business volume（Traffic Volume Measurements, abbreviation TVM measurements）.The measurement just performs for measuring UE Business data transmission amount size, and report measurement results are to RNC.When the increase of uplink business data amount causes RNC determinations will UE from FACH state be switched to DCH states when, RNC issues NBAP message（Node-B Application Part, abbreviation NBAP） To base station, to indicate that UE distributes special E-DCH resource as this for base station, returns to a NBAP message to respond RNC.RNC is according to response Plan of distribution in NBAP message, issue a radio resource control signaling（Radio Resource Control, abbreviation RRC Signaling）To UE.UE is synchronous with base station realization according to the information of the special E-DCH resource of acquisition.Specially：In the special of the distribution With uploading data in E-DCH resource.After base station detects UE upload data on the special E-DCH channels, release originally with The common E-DCH resource that UE is established.UE is synchronous with base station completion, and data start to transmit, and UE switches to DCH states, is returned to RNC One RRC signaling is to respond RNC.

The research process of the present invention are being carried out, the inventors discovered that prior art at least has the defects of following：

When configuring special E-DCH resource to UE in base station, if the UE of connection is more, base station does not have available special E- DCH resources, i.e., can not be UE collocating uplink DPCHs, and UE can not improve uplink speed.In addition, up special The foundation of physical channel with it is synchronous in, the signaling between base station and UE exchanges more, easily increases current network load.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made Embodiment, belong to the scope of protection of the invention.

Embodiment 1：

Referring to Fig. 1, a kind of switching method of channel status is present embodiments provided, suitable for radio network controller （Radio Network Controller, abbreviation RNC）.When RNC control user terminal switching wireless heterogeneous networks connection status When, RNC control base stations switch the channel status of the currently used channel of the user terminal, to meet user terminal in the wireless money of switching Data transfer after source control connection status needs.

Its step and operation principle are mainly as follows：

Step 101：Network controller sends the first modification control message of channel resource state to base station.

In the present embodiment, the modification control message of the channel resource state is used for：Indicate base station according to first modification Channel resource call number in control message, determines channel resource to be modified, by the state of channel resource to be modified by original money Source status modifier is target resource state.After RNC determines that the RRC connection status of a user terminal need to be changed, RNC is repaiied by this Change control message signals base to modify.

In the present embodiment, channel resource includes：The control information of one group of channel and this group of channel correlation（Main scrambler, Channel indicates number）, user terminal is to the transmittability configuration information of the channel, and transmission carrying energy of the base station to the channel Configuration information of power etc..

In the present embodiment, the state of channel resource is：Private resource state or public resource state.An if channel pair The channel resource answered is in private resource state, and the channel can carry substantial amounts of data, and the transmission speed of data is very fast, is applied to The data services such as data download.And the RRC connection status of user terminal and the channel is DCH states.If the channel of a channel Resource is in public resource state, and the channel can carry a small amount of data, and message transmission rate is slower, suitable for instant messaging etc. Business.And the RRC connection status of user terminal and the channel is FACH state.

For example, before the first modification control message of channel resource state is sent, network controller can pass through TVM Measurement, confirms whether user terminal needs to switch current RRC connection status.Concretely comprise the following steps：User terminal is according to certain Time interval, it is transmitted measuring business volume（Traffic Volume Measurements, abbreviation TVM）, to measure the user Terminal need to send the size of data when handling current business.TVM measurement results are reported RNC by user terminal, RNC according to TVM measurement results, decide whether to control user terminal switching RRC connection status.

When the data that a certain business need to be sent are smaller, RNC can control user terminal to cut current RRC connection status It is changed to CELL-FACH states；When the data that a certain business need to be sent are larger, RNC can control user terminal to connect current RRC The state of connecing switches to CELL-DCH states.User terminal under different RRC connection status needs have different transmission performances Channel realizes data transfer.And the transmission state of channel is managed setting by base station, base station by manage channel resource with up to To management channel status, therefore RNC sends the modification control message of channel resource state to base station, to change channel resource state, User terminal is set to complete the switching of RRC connection status.

Step 102：Network controller receives the first response message that the base station is sent.

In the present embodiment, first response message includes the base station according to the modification control message to the channel resource shape The modification confirmation of state.According to current network environment, if base station can change the state of the channel resource to be modified, base The modification confirmation sent to network controller of standing confirms this modification for base station.If current network conditions do not allow base station The state of the channel resource is changed, then it is that base station does not allow this modification that base station sends modification confirmation to network controller.

Step 103：Judge whether the modification confirmation in first response message is that confirm modification this is to be modified for base station The state of channel resource, if it is, performing step 104.
