Abstract

The invention is used for saving air-interface resources. The method comprises: when terminal works at PCH state of connection mode and user initiates a new service, a pseudo combined service configuration approach is used to only allocate air-interface bandwidth for the new service but not allocate air-interface bandwidth for original service, and meantime configuring the measurement control; if the original service has no data to be transmitted, then the user's terminal state and channel parameters keep unchanged; if original service has data to be transmitted, the radio network controller initiates a reconfiguration process for the radio bearer in order to allocate air-interface resources to the original service.

Description

Wireless bearing configuration method in the mobile communication system

Technical field

The present invention relates to a kind of wireless bearing configuration method, particularly relate to the wireless bearing configuration method in a kind of mobile communication system.

Background technology

In 3-G (Generation Three mobile communication system), UE (user terminal) has two basic operator schemes: idle pulley and connection mode, as shown in Figure 1.If UE will make a call or paged or other reasons, UE initiates RRC (Radio Resource control) connection and sets up process so, enter connection mode, connection mode is further divided into one of four states: CELL_DCH, CELL_FACH, CELL_PCH and URA_PCH state, the main purpose of Hua Fening is in order to save air interface (abbreviation is eated dishes without rice or wine or the UU mouth) Radio Resource, to reduce UE battery consumption etc. like this.

Generally speaking, the activity of UE reduces successively under CELL_DCH, CELL_FACH, CELL_PCH and the URA_PCH state, so system is also fewer and feweri to the resource that UE distributes.For example, suppose that UE initiates the business in a PS (packet switching) territory, as web page browsing or file download etc., network side may be configured to UE earlier the CELL_DCH state under the connection mode so, this state lower network is distributed the physical channel of a special use to UE, if traffic carrying capacity reduces after a period of time, network side may be configured to UE the CELL_FACH state according to the measuring business volume report that UE reports, this state lower network is not given the UE dedicated physical channels allocated, and be to use common signal channel (uplink random access channel RACH and descending forward access channel FACH) to come command transmitting and data, if traffic carrying capacity becomes littler even does not have transfer of data in a period of time, network can further be configured to UE CELL_PCH or URA_PCH state so, CELL_PCH state and URA_PCH state is referred to as the PCH state herein.Under the PCH state, UE can not transmit and receive data, and does not also promptly take interface-free resources, and UE adopts the mode of discontinuous reception (DRX) beep-page message simultaneously, to reduce battery consumption.CELL_PCH is more similar to the URA_PCH state, from the terminal angle, the main distinction of the two is need initiate under the CELL_PCH state cell update when UE moves to new sub-district (cell), the sub-district at its place of informing network side, and the UE under the URA_PCH state not necessarily needs to initiate cell updating course when moving to new sub-district, belong to new UTRAN Acceditation Area (URA but have only when new sub-district, the scope of a URA comprises some sub-districts) time just initiate the URA renewal process, therefore with respect to the CELL_PCH state, the UE under the URA_PCH state and the signaling interaction times of network side still less, also just more power saving.

As known to those skilled in the art, support that composite service is a UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) a essential characteristic, when being in PCH state following time, UE may initiate new business, in this case, if network side uses inappropriate wireless bearing configuration method, will cause the waste of interface-free resources.

For example, for supporting PoC service (Push-to-talk over Cellular, a kind of half-duplex call business based on the PS territory) terminal, for shortening calling establishment time delay, improve user's satisfaction, UE may be in the PCH state after finishing SIP (session initiation protocol) registration, so just can very fast access network when UE need initiate PoC service, begin to converse.If the UE under the PCH state will initiate CS (circuit switching) territory business, during as the speech business of 12.2kbps, the RNC of network side (radio network controller) will be in the face of RB (radio bearer) the parameter configuration problem of two RAB (RAB), one is the RAB of newly-built speech business correspondence, for example corresponding data speed is 12.2kbps, one is the RAB of original PS territory PoC correspondence, and for example corresponding data speed is 16kbps; And UE is in the PCH state under original service conditions, and newly-built speech business requires to be based upon the CELL_DCH state, to guarantee the real-time requirement of speech business.At present, existing RB method for parameter configuration is: the RB parameter that disposes two RAB correspondences simultaneously, promptly on eating dishes without rice or wine, distribute respective bandwidth 12.2kbps to speech business, give the bandwidth 16kbps of the original application of PS traffic assignments or less bandwidth simultaneously, as 8kbps, this method is called composite service RB method for parameter configuration.Because UE can not initiate PoC service during the CS conversation, therefore do not transmit any data in the bandwidth of air-interface of whole C S conversation period P S correspondence, therefore wasted interface-free resources.

Generally speaking, to have used traffic carrying capacity in PS business and a period of time be 0 situation because the PCH state is used for UE mostly, therefore at this moment, if UE initiates new business, network side RNC adopts the professional RB method for parameter configuration of combinations thereof, eating dishes without rice or wine also to distribute certain bandwidth for original PS business, because original business does not have data volume or data volume very little duration of new business, there is waste more or less in interface-free resources so.

Summary of the invention

The technical problem to be solved in the present invention provides the wireless bearing configuration method in a kind of mobile communication system, and when mobile communication terminal was in the PCH state, UE will use under the situation of composite service, avoided or reduce the waste of interface-free resources.

For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions: be in as UE under the PCH state of connection mode, when UE initiates new business, adopt pseudo-composite service collocation method, only distribute bandwidth of air-interface to new business, and original business is not distributed bandwidth of air-interface, allocating and measuring control simultaneously; If original business does not have data to transmit, then user terminal state and channel parameter remain unchanged; If original business has data to need transmission, radio network controller is initiated the radio bearer reconfiguration course, gives original traffic assignments interface-free resources.

The present invention has such beneficial effect owing to adopted technique scheme, has promptly saved interface-free resources.

Embodiment

The present invention is further detailed explanation below in conjunction with accompanying drawing.

Be in as UE under the PCH state of connection mode, when UE initiates new business, in order to reduce waste to interface-free resources, can carry out pseudo-composite service configuration as follows: for new business, RNC is according to existing method configuration RB parameter, for original business, also dispose a cover RB parameter, comprise RB map information, transport channel parameters, physical channel parameters etc., the just corresponding speed of eating dishes without rice or wine is 0, and soon the transmission block number is set to 0 in the transformat.Like this, UE receives that RB sets up after the message in the RLC that sets up the new business correspondence (Radio Link control) entity, LogCH (logic channel) and TrCH (transmission channel), also sets up original professional corresponding RLC entity, LogCH, TrCH etc.The purpose of doing like this is that UE can carry out measuring business volume to original business, when original business begins transfer of data is arranged, makes RNC carry out RB by the transmission measurement report and reshuffles, give the certain bandwidth of air-interface of original traffic assignments.

Therefore, with reference to Fig. 2, the radio bearer layoutprocedure can be carried out as follows:

In step 201, UE is in the PCH state.Described PCH state generally is after UE initiates the PS business, is that the wireless resource management algorithm of network side can be with UE state transition to the PCH state under 0 the situation in a period of time traffic carrying capacity.

When UE initiates new business, enter step 202, at this moment new business is based upon on the DCH, UE enters the CELL_DCH state, new business is set up and is adopted above-mentioned pseudo-composite service collocation method in the process, only distribute bandwidth of air-interface, and do not give original traffic assignments bandwidth of air-interface, allocating and measuring control simultaneously to new business.

After pseudo-composite service has disposed, enter step 203.At this moment judge whether original business has data to transmit, if original business does not have data to transmit, then UE state and channel parameter remain unchanged; If original business has data to need transmission, then enter step 204, whether whether original here business has data will transmit according to the measuring business volume result is judged greater than 0.Described measuring business volume comprises that the upstream traffic that the downlink traffic of network side is measured and UE reports measures, and wherein to report threshold setting be 0 to traffic carrying capacity, promptly in case there are data to need to transmit, sends measurement report at once.

In step 204, RNC initiates the RB reconfiguration course, gives original traffic assignments interface-free resources, and the much bandwidth of concrete configuration are determined by RNC, generally according to measuring business volume report decision.At this moment, if new business is the CS speech business, new business can not be affected in the RB reconfiguration course.
