Description

A kind of changing method of channel status and network controller and base station and communication system

Technical field

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

Background technology

User terminal (User Equipment is called for short UE) accesses each base station by land radio access web, realizes radio communication.Wireless heterogeneous networks connection status (the Radio Resource Control of user terminal, be called for short RRC connection status) four kinds of states can be subdivided into, the present invention relates generally to dedicated connection status (CELL-DCH, Dedicated Channel) and common channel data state (CELL-FACH, Forward Access Channel), be called for short DCH state and FACH state.DCH state principal character is: UE adopts DPCH, and data transmission bauds is high, is applicable to continuous, mass data transmission, as made a phone call, downloading.FACH state principal character is: UE adopts public or shared transmission channel, and message transmission rate is low, is applicable to little packet data transmission online for a long time, such as signaling, instant messaging.

And when data upstream transmission, the difference of DCH state and FACH state is: DCH state can take DPCH for a long time and carry out mass data transmission, FACH state can only take DPCH in short-term.In prior art, the channel for UE transmitting uplink data is enhancing special uplink channel (Enhanced uplick DCH is called for short E-DCH).Radio network controller (Radio Network Controller is called for short RNC) is managed for configuration the E-DCH resource of base station.RNC configures a total E-DCH resource pond to base station, and the arbitrary E-DCH resource in resource pool comprises: the information (main scrambler, channel logo number) of an E-DCH channel and associated control channel, UE to the configuration information of the up transmitting capacity of this E-DCH channel and base station to the configuration information etc. of the transmission bearer ability of this E-DCH channel.E-DCH resource comprises: special E-DCH resource and common E-DCH resource, and network controller distributes corresponding E-DCH resource according to the RRC connection status of UE to UE.The E-DCH resource distributing to FACH state is common E-DCH resource, and the E-DCH resource distributing to DCH state is special E-DCH resource.Between UE and base station, the E-DCH resource according to distributing sets up corresponding E-DCH channel, to realize transfer of data.

Along with the large-scale application of intelligent terminal, UE has paroxysmal data business volume under FACH state to be increased.The data traffic of these bursts of traffic increases gradually, or bursts of traffic is follow-up when having a large-data operation, UE need often from FACH State Transferring to DCH state to obtain higher message transmission rate, after DTD, UE needs again from DCH State Transferring to FACH state to save system resource.At this moment, the time that UE takies common E-DCH resource is shorter, and the UE under FACH state can not carry out the business of big data quantity.And it is longer to take time of special E-DCH resource at the UE of DCH state, also can carry out the business of big data quantity.Therefore, when the data volume of the uplink service of UE has greatly changed, UE needs to switch between FACH state and DCH state.

In the prior art, RNC adopts the mode of distributing, E-DCH resource pond in management of base station, and when realizing the switching of UE state, the channel between base station and UE is set up.Concrete grammar is as follows:

Use common E-DCH resource to transmit when UE is in FACH state, according to certain time interval, UE carries out transport service measurement amount (Traffic Volume Measurements is called for short TVM and measures).The size of business data transmission amount of this measurement for measuring UE and just performing, and report measurement results is to RNC.When the increase of uplink business data amount causes RNC to determine UE to be switched to DCH state from FACH state, RNC issues NBAP message (Node-B Application Part, be called for short NBAP) to base station, with indicate base station for this reason UE distribute special E-DCH resource, return a NBAP message to respond RNC.RNC, according to the plan of distribution in response NBAP message, issues a radio resource control signaling (Radio Resource Control is called for short RRC signaling) to UE.UE, according to the information of the special E-DCH resource obtained, realizes synchronous with base station.Be specially: uploading data in the special E-DCH resource of this distribution.After base station detects the uploading data of UE on this special E-DCH channel, the common E-DCH resource that the original and UE of release sets up.UE and base station complete synchronous, and data start transmission, and UE switches to DCH state, returns a RRC signaling to respond RNC to RNC.

Carrying out in research process of the present invention, the present inventor finds that prior art at least exists following defect:

During in base station to UE configure dedicated E-DCH resource, if the UE connected is more, base station does not have available special E-DCH resource, and cannot be namely UE collocating uplink DPCH, UE can not improve uplink speed.In addition, uplink special physical channel foundation with synchronous in, 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, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

Embodiment 1:

See Fig. 1, present embodiments provide a kind of changing method of channel status, be applicable to radio network controller (Radio Network Controller is called for short RNC).When RNC controls user terminal switching wireless heterogeneous networks connection status, RNC controls the channel status that base station switches the current use channel of this user terminal, to meet the transfer of data needs of user terminal after switching wireless heterogeneous networks connection status.

Its step and operation principle are mainly as follows:

Step 101: network controller is to the first change control message of base station transmitting channel resource status.

In the present embodiment, the change control message of this channel resource state is used for: instruction base station is according to the channel resource call number in this first change control message, determining channel resource to be modified, is target resource state by the state of channel resource to be modified by source material status modifier.Determine to revise the RRC connection status of a user terminal at RNC after, RNC is modified by this change control message signals base.

In the present embodiment, channel resource comprises: the control information (main scrambler, channel indicate number) that one group of channel and this group channel are relevant, user terminal are to the transmittability configuration information of this channel, and base station is to the configuration information etc. of the transmission bearer ability of this channel.

In the present embodiment, the state of channel resource is: private resource state or public resource state.If the channel resource that a channel is corresponding is in private resource state, this channel can carry a large amount of data, and the transmission speed of data is very fast, is applicable to the data services such as data download.And the RRC connection status of user terminal and this channel is DCH state.If the channel resource of a channel is in public resource state, this channel can carry data in a small amount, and message transmission rate is comparatively slow, is applicable to the business such as instant messaging.And the RRC connection status of user terminal and this channel is FACH state.

For example, before the first change control message of transmitting channel resource status, network controller is measured by TVM, confirms that user terminal is the need of switching current RRC connection status.Concrete steps are: user terminal, according to certain time interval, carrying out transport service measurement amount (Traffic Volume Measurements is called for short TVM), to measure this user terminal when processing current business, need send the size of data.TVM measurement result is reported RNC by user terminal, and RNC, according to TVM measurement result, determines that whether controlling user terminal switches RRC connection status.

When the data that a certain business need send are less, RNC can control user terminal and current RRC connection status is switched to CELL-FACH state; When the data that a certain business need send are larger, RNC can control user terminal and current RRC connection status is switched to CELL-DCH state.User terminal under different RRC connection status needs the channel with different transmission performance to realize transfer of data.And the transmission state of channel carries out management setting by base station, base station by management channel resource to reach management channel state, therefore RNC is to the change control message of base station transmitting channel resource status, to revise channel resource state, user terminal is made to complete the switching of RRC connection status.

Step 102: network controller receives the first response message that described base station sends.

In the present embodiment, this first response message comprises this base station according to the amendment confirmation of this change control message to this channel resource state.According to current network environment, if the state of this channel resource to be modified can be revised in base station, then base station is that base station confirms this amendment to the amendment confirmation that network controller sends.If current network conditions does not allow base station to revise the state of this channel resource, then base station sends amendment confirmation to network controller is that base station does not allow this amendment.

Step 103: judge that whether amendment confirmation in this first response message confirms the state of this channel resource to be modified of amendment as base station, if so, then perform step 104.

For example, if network controller is according to this amendment confirmation, judge that base station is current to modify to the state of this channel resource, then can be, but not limited to end step, waiting for next step operation or send new channel configuration messages to base station, is the channel that terminal configuration is new, to meet terminal traffic needs, this step is prior art, does not repeat them here.

Step 104: network controller sends the first radio resource control signaling to base station, so that base station sends this first radio resource control signaling to user terminal.

In the present embodiment, this first radio resource control signaling comprises: the first transmittability configuration information.In the prior art, the channel resource state of a type is configured with a transmittability configuration information, is pre-set by RNC.This transmittability configuration information effect on the subscriber terminal, for the data transmission capabilities of configure user terminal on channel, such as: the maximum transmitted bearing capacity etc. of terminal maximum data transfer rate on this channel, this channel.This transmittability configuration information prestores in the rnc, and channel resource state and a transmittability configuration information of each type match.

In this step, according to the target resource state of channel resource to be modified, the transmittability configuration information that this target resource state matches by RNC, sends to base station by the first radio resource control signaling, is transmitted to user terminal by base station.
