Abstract
The embodiment of the invention discloses a method and a device for selecting a service loading mode. The method comprises the following steps that: a wireless network controller judges whether a user terminal is on an interference fringe or not; when judging that the user terminal is on the interference fringe, the wireless network controller acquires an uplink/downlink priority identifier; and the wireless network controller selects the service loading mode according to the uplink/downlink priority identifier. In the embodiment of the invention, when the user terminal is on the interference fringe, the wireless network controller preferentially selects DCH loading as the service loading mode, and therefore the access success rate is not influenced and the data throughput of a cell is improved.
Description
Technical field
The present invention relates to wireless communication technology field, particularly relate to a kind of system of selection and device of service bearer mode.
Background technology
In 3G (Third Generation) Moblie, UE (User Equipment, user terminal) state can be divided into idle pulley and connection mode, wherein connection mode is divided into CELL_DCH (Dedicated Channel again, dedicated channel), CELL_FACH (Forward Access Channel, the preceding channel of transferring), CELL_PCH (Paging Channel, paging channel) and four kinds of states of URA_PCH (UTRAN Registration Area_Paging Channel, UTRAN Registration Area _ paging channel).Wherein under the CELL_DCH state, system can distribute a dedicated channel to UE, is used for transfer of data.
Support R4 and HSPA (High-Speed PacketAccess simultaneously at one, the high-speed packet access) 3G (The Third Generation, the third generation) network, to being in CELL_DCH state user's business, its service bearer mode can be used DCH service bearer mode, also can use HSPA service bearer mode, also can mix DCH service bearer mode or the HSPA service bearer mode used, concrete service bearer mode is as shown in table 1.
Table 1: service bearer mode
The uplink service bearing mode comprises DCH service bearer mode and E-DCH service bearer mode.Wherein, E-DCH (Enhanced Dedicated Channel strengthens dedicated channel) service bearer mode belongs to HSPA service bearer mode, is used for the transfer of data that happens suddenly in up link.The downlink business bearing mode comprises DCH service bearer mode and HS-DSCH (High-Speed Downlink Shared Channel, high-speed downlink shared channel) service bearer mode.Wherein, HS-DSCH service bearer mode belongs to HSPA service bearer mode, is used to increase data rate for downlink.
Adopt HSPA service bearer mode to compare and be that the former has key properties such as fast dispatch, AMC (Adaptive Modulation and Code, adaptive modulation and coding), the automatic retransmission technique of rapid mixing with employing DCH service bearer mode.Wherein, AMC is a kind of link adaptation techniques, and it can be by adjusting the modulation and the coded system of transmission data adaptively, and compensation is because the influence of fading that channel and interference variations are caused to received signal.AMC supports QPSK (Quadrature Phase Shift Keying, Quadrature Phase Shift Keying modulation) and two kinds of modulation systems of 16QAM (Quadrature Amplitude Modulation, quadrature amplitude modulation), supports range of code rates from R=1/3 to R=1.That is to say, when the channel condition of user terminal is better, adopt high order modulation and high code check,, make full use of system resource and improve transmission rate, obtain the higher data throughput as 16QAM modulation and R=1; When the channel condition of user terminal is relatively poor, adopt low-order-modulated and low code check, as QPSK modulation and R=1/3, improve transmission reliability, reduce the degree of data re-transmission.
User terminal is when carrying out service access, by RNC (Radio Network Controller, radio network controller) select concrete service bearer mode according to up-downgoing priority symbol, service rate and up-downgoing admission judgment result, concrete steps as depicted in figs. 1 and 2.When up-downgoing priority symbol during for following row major, if the downstream rate of requested service surpasses the service rate thresholding of configuration, then RNC is preferably downlink business and selects HS-DSCH service bearer mode, carries otherwise RNC is preferably descending selections DCH.Instantly after industry affair bearing mode was selected, when acceptance judging, RNC was preferably uplink service and selects E-DCH service bearer mode, and the DCH carrying is selected in the back.When the up-downgoing priority symbol was last row major, if the upstream rate of requested service surpasses the service rate thresholding of configuration, then RNC was preferably uplink service and selects E-DCH service bearer mode, otherwise RNC is preferably up selection DCH service bearer mode.When acceptance judging, RNC is preferably downlink business and selects the HS-DSCH carrying, and the DCH carrying is selected in the back.
This method when not influencing the access success rate, is carried middle and high rate business with HSPA service bearer mode as far as possible, carries than low rate traffic with DCH service bearer mode.If with the business of HSPA carrying, understand owing to HSPA control channel expense, follow DPCH (DedicatedPhysical Control Channel, Dedicated Physical Control Channel) channel overhead, reduce resource utilization than low rate.
In realizing process of the present invention, the inventor finds prior art, and there are the following problems at least:
Prior art is not considered based on the channel condition or the locus of user terminal when selecting professional radio bearer mode.May cause the relatively poor user terminal of channel condition in the sub-district thus, or be in the user terminal of cell edge region, use the HSPA bearer service, because low-order-modulated and low code check have reduced the data throughout of sub-district.And channel condition user terminal preferably in the sub-district, may be because sub-district HSPA resource be shared by the relatively poor user terminal of channel condition, thereby when HSPA service bearer mode acceptance judging, fail, finally can only adopt DCH service bearer mode, reduced the data throughout of sub-district.

When selected service bearer mode is E-DCH service bearer mode, the acceptance judging condition is: RNC judges whether existing available resources satisfy professional to following the requirement of DPCH resource in the sub-district, the HSUPA user terminal that requirement and the sub-district of GBR (Guaranteed Bit Rate guarantees bit rate) are supported is counted requirement.
When selected service bearer mode is HS-DSCH service bearer mode, the acceptance judging condition is: RNC judges whether existing available resources satisfy business to following the requirement of DPCH resource in the sub-district, and the HSDPA user terminal that requirement and the sub-district of GBR are supported is counted requirement.
RNC is according to the up-downgoing priority symbol of being obtained in the step 403, and the service bearer mode in the table 2 and the priority of each bearing mode, selects the service bearer mode, and selected service bearer mode is carried out acceptance judging.
Concrete, as shown in Figure 5, when up-downgoing priority symbol during for row major down, RNC selects the detailed process of service bearer mode to be:
According to the height of each service bearer mode priority, RNC is the service bearer mode 1 in the option table 2 at first, promptly descending DCH and up DCH service bearer mode, and selected service bearer mode 1 carried out acceptance judging.When the result who selected service bearer mode 1 is carried out acceptance judging was the acceptance judging success, RNC adopted selected service bearer mode 1 to communicate; When the result who selected service bearer mode 1 is carried out acceptance judging fails for acceptance judging, RNC will reselect the service bearer mode.According to table 2 as can be known, RNC selects priority to be only second to the service bearer mode 2 of service bearer mode 1, and promptly descending DCH and up E-DCH service bearer mode are as the service bearer mode.
RNC repeats the step that acceptance judging was selected and carried out to above-mentioned service bearer mode according to the priority of each service bearer mode in the table 2, up to when carrying out selected service bearer mode till admission judgment result is the acceptance judging success.Need to prove that carry out admission judgment result when four kinds of service bearer modes in the his-and-hers watches 2 and be acceptance judging when failure, the service bearer mode is selected failure.
In the embodiments of the invention when UE carries out service access, if UE is in interference fringe, then RNC preferential DCH of selection when selecting the service bearer mode carries, and when the result who selected service bearer mode is carried out acceptance judging fails for acceptance judging, reselect the service bearer mode, when not influencing the access success rate, improved the data throughout of sub-district.
Embodiments of the invention provide a kind of system of selection of service bearer mode, and when UE carried out service access, RNC judged that UE is in interference fringe and obtains the up-downgoing priority symbol.With the up-downgoing priority symbol is the up example that is preferably, and RNC selects the service bearer mode and carries out acceptance judging, and when the result of acceptance judging is the acceptance judging success, reselects the service bearer mode, and concrete steps as shown in Figure 6.
At a 3G network of supporting R4 and HSPA simultaneously, to being in CELL_DCH state user's business, can select DCH service bearer mode, also can select HSPA service bearer mode, also can mix DCH service bearer mode or the HSPA service bearer mode used.Wherein, concrete bearing mode is as shown in table 1.
Selecting HSPA service bearer mode to compare with selection DCH service bearer mode is, the former has key properties such as fast dispatch, AMC, the automatic retransmission technique of rapid mixing, improve transmission reliability, reduced the degree of data re-transmission, improved the data throughout of sub-district.
UE channel condition or locus change are meant that UE enters non-interference fringe or enters interference fringe from non-interference fringe from interference fringe.At this moment, the UE relevant parameter that is stored among the RNC changes, and triggers RNC and judges whether UE is in interference fringe.
When RNC judges UE when interference fringe enters non-interference fringe, the concrete steps that RNC selects the service bearer mode as depicted in figs. 1 and 2;
When RNC judges UE when non-interference fringe enters interference fringe, RNC forwards step 603 to.
Concrete, RNC judges that the condition whether UE is in interference fringe is:
When satisfy all adjacent areas:
During the PCCPCH_RSCP of PCCPCH_RSCP-adjacent area, this sub-district＞=TH+Hysteresis/2, RNC judges that UE is in non-interference fringe;
As long as otherwise have an adjacent area to satisfy:
During the PCCPCH_RSCP of PCCPCH_RSCP-adjacent area, this sub-district＜TH-Hysteresis/2, RNC judges that UE is in interference fringe.
Perhaps
When satisfy all adjacent areas:
During (this sub-district PCCPCH_RSCP+CIOS)-(PCCPCH_RSCP+CIOT of adjacent area)＞=TH+Hysteresis/2, RNC judges that UE is in non-interference fringe;
As long as otherwise have an adjacent area to satisfy:
During (this sub-district PCCPCH_RSCP+CIOS)-(PCCPCH_RSCP+CIOT of adjacent area)＜TH-Hysteresis/2, RNC judges that UE is in interference fringe.
Wherein, TH is a thresholding, and CIOS is this sub-district biasing, and CIOT is the adjacent area biasing, and PCCPCH_RSCP is Primary Common Control Physical Channel _ received signal code power, and Hysteresis is sluggish parameter.Send to RNC after the PCCPCH_RSCP that removes described this sub-district PCCPCH_RSCP and described adjacent area is measured by UE, other parameters are by the Operation and Maintenance setting and be stored among the RNC.
The up-downgoing priority symbol is divided into descending priority symbol or up priority symbol, by the Operation and Maintenance setting, and is stored among the RNC.When the up-downgoing priority symbol was last row major, RNC was preferably uplink service and selects bearing mode; When the up-downgoing priority symbol is that RNC is preferably downlink business and selects bearing mode when descending row major.
Embodiments of the invention are that the up example that is preferably describes with the up-downgoing priority symbol.
When the up-downgoing priority symbol was last row major, RNC was preferably uplink service and selects bearing mode.When selecting the service bearer mode, the priority of DCH service bearer mode is higher than E-DCH service bearer mode in the uplink service bearing mode; The priority of DCH service bearer mode is higher than HS-DSCH service bearer mode in the downlink business bearing mode.
According to above-mentioned priority principle, can draw when the up-downgoing priority symbol is last row major, the service bearer mode has four kinds, and is specifically as shown in table 3.
Table 3: service bearer mode (going up row major)
Wherein, four kinds of service bearer modes in the table 3 have priority, and the rank of priority is successively decreased successively by service bearer mode 1 to service bearer mode 4.
RNC is according to the up-downgoing priority symbol of being obtained in the step 603, and the service bearer mode in the table 3 and the priority of each bearing mode, selects the service bearer mode, and selected service bearer mode is carried out acceptance judging.
Concrete, as shown in Figure 5, when the up-downgoing priority symbol was last row major, RNC selected the detailed process of service bearer mode to be:
According to the height of each service bearer mode priority, RNC is the service bearer mode 1 in the option table 3 at first, promptly up DCH and descending DCH service bearer mode, and selected service bearer mode 1 carried out acceptance judging.When the result who selected service bearer mode 1 is carried out acceptance judging was the acceptance judging success, RNC adopted selected service bearer mode 1 to communicate; When the result who selected service bearer mode 1 is carried out acceptance judging fails for acceptance judging, RNC will reselect the service bearer mode.According to table 3 as can be known, RNC selects priority to be only second to the service bearer mode 2 of service bearer mode 1, and promptly up DCH and descending HS-DSCH service bearer are as the service bearer mode.
RNC repeats the step that acceptance judging was selected and carried out to above-mentioned service bearer mode according to the priority of each service bearer mode in the table 3, up to when carrying out selected service bearer mode till admission judgment result is the acceptance judging success.Need to prove that carry out admission judgment result when four kinds of service bearer modes in the his-and-hers watches 3 and be acceptance judging when failure, the service bearer mode is selected failure.
In the embodiments of the invention when the channel condition of UE or locus change, if UE enters interference fringe from non-interference fringe, then RNC preferential DCH of selection when selecting the service bearer mode carries, and when the result who selected service bearer mode is carried out acceptance judging fails for acceptance judging, reselect the service bearer mode, thereby when not influencing the access success rate, improved the data throughout of sub-district.
