Description
Technical field
The present invention relates to the processing method of uplink macro diversity in the mobile communication system, especially be applicable to the processing method of the uplink macro diversity of flattening architectures of communication networks and conventional communication networks framework, belong to communication technical field.
Background technology
In mobile communication system, universal mobile telecommunications system (Universal MobileTelecommunications System for example, be called for short UMTS), as subscriber equipment (User Equipment, be called for short UE) in the time of will carrying out handover, in order to keep continuous connection to guarantee that the quality of Radio Link, UE just set up and being connected of new sub-district before the connection that disconnects old sub-district, soft handover just.Therefore in soft handover, UE communicates by letter with two base stations (Node B) that participate in switching at least, the quality of the signal communication when being in handover for improving UE, and the data when keeping handover are not lost, UE and universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio Access Network, be called for short UTRAN) merge carry out diversity from a plurality of signal of base station respectively, this technology is called grand diversity.At code division multiple access (Code Division Multiple Access, abbreviation CDMA) in the network, as long as UE enters the switch area and will connect with two or more base stations, just needing to carry out uplink macro diversity merges, and suitable ratio is occupied at whole network coverage in this switch area, generally 30% to 40%, therefore how carrying out the uplink macro diversity merging is very important to network on the engineering.The uplink macro diversity of just having introduced below under several different scenes merges.
Uplink macro diversity under traditional UMTS framework merges, for example, the signal that UE launches in up link is received by several (being example with two) base station, after demodulation, be forwarded to radio network controller (RadioNetwork Controller, be called for short RNC), RNC merges two paths of data, and just uplink macro diversity merges, to improve the quality of upward signal, as shown in Figure 1.
And in the network architecture of flattening, do not have RNC, carry out uplink macro diversity by the base station and merge.As shown in Figure 2, if the merging method according to the conventional communication networks framework directly moves on to the function that uplink macro diversity merges in the base station 11, be exactly that all base stations 12 all are transmitted to base station 11 with second packet, first packet of second packet and it being received by base station 11 merges.In order to express easily, represent other base stations in base station that UE is resident and the Active Set with base station 11 and base station 12 respectively in the drawings, and the packet that the UE that receive base station 11 and base station 12 is sent is called first packet and second packet.
Existing two kinds of improving one's methods at the merging of the uplink macro diversity under the flattening architectures of communication networks.
First method: send announcement (notification) for base station 11, be specially: cyclic redundancy check (CRC) code (the Cyclic Redundancy Code of first packet of receiving when base station 11, be called for short CRC) when verification is correct, (wherein solid line is represented data flow as Fig. 3, dotted line is represented signaling flow, following application structure schematic diagram adopts same expression mode) shown in, base station 11 directly is forwarded to equipment of the core network with first packet, ignores the notice message that base station 12 sends; During the CRC check mistake of first packet of receiving when base station 11, as shown in Figure 4, base station 11 waits for that base station 12 sends notice message, therefrom select a base station 12 to require it that the packet of receiving is forwarded after receiving the notice message that base station 12 sends, this selected base station 12 sends packet for base station 11 again.
Second method: base station 11 sends indication (instruction), be specially: when the CRC check of first packet of receiving when base station 11 is correct, as shown in Figure 5, base station 11 directly is forwarded to equipment of the core network with first packet, and all base stations 12 transmission Indication messages in Active Set do not allow them send packets to base station 11; During the CRC check mistake of first packet of receiving when base station 11, as shown in Figure 6, base station 11 does not send Indication message, wait for that base station 12 sends packet to it, behind the timer expiry that preset in inside base station 12, second packet that them are received in the base station 12 that all CRC check are correct sends to base station 11.
Above-mentioned first method is in the base station 11 when receiving the good or bad packet of quality, base station 12 all sends signaling to base station 11, above-mentioned second method is in the base station 11 when receiving the measured packet of matter, base station 11 still sends signaling to base station 12, and 11 when receiving poor quality's packet in the base station, also have the wait time-delay of base station 12, this has increased the traffic and communication delay between base station 11 and the base station 12 greatly, also just is equivalent to reduce the capacity of system.
Summary of the invention
The technical problem to be solved in the present invention just provides a kind of processing method of uplink macro diversity, guarantees to carry out effectively the processing of uplink macro diversity data, reduces simultaneously by grand diversity as far as possible and handles the base station that causes and/or the traffic between the RNC.
For achieving the above object, the invention provides the processing method of uplink macro diversity in a kind of mobile communication system, in soft switching process, may further comprise the steps: first base station receives first packet that UE sent, and carry out quality inspection, if quality inspection is by then sending to equipment of the core network with described first packet.
In order further to reduce the mutual of data, also comprise if described first base station is not passed through the quality inspection of first packet, then described first base station sends advertised information to second base station that is associated with described UE, quality inspection is carried out to second packet that described UE sent that receives in described second base station, if quality inspection is by then sending to described first base station with described second packet, described first base station merges second packet that receives and sends to equipment of the core network.
The present invention also provides the processing method of uplink macro diversity in a kind of mobile communication system, in soft switching process, may further comprise the steps: first base station receives first packet that UE sent, and carry out quality inspection, if quality inspection is by then sending to equipment of the core network with described first packet by the RNC under described first base station.
In order further to reduce the mutual of data, also comprise if described first base station is not passed through the quality inspection of first packet, then described first base station sends advertised information by a described RNC to second base station that is associated with described UE, quality inspection is carried out to second packet that described UE sent that receives in described second base station, if quality inspection is by then sending to a described RNC with described second packet, a described RNC merges second packet that receives and sends to equipment of the core network.
In order to be applicable to that further first base station and second base station belong to the situation of different RNCs, also comprise if described first base station is not passed through the quality inspection of first packet, then described first base station sends advertised information by the 2nd RNC under a described RNC and described second base station to described second base station, quality inspection is carried out to second packet that described UE sent that receives in described second base station, if quality inspection is by then sending to a described RNC with described second packet by described the 2nd RNC, a described RNC merges second packet that receives and sends to equipment of the core network.
When the present invention receives the measured packet of matter in first base station, between the base station without any Signalling exchange, alleviated offered load significantly.When even if ropy packet is received in first base station, also only need to increase a signaling and give the second all base stations, and second base station of only receiving the measured packet of matter issues first base station with data, and this compares with traditional ascending macro diversity combining method still has superiority.Because usually second number of base stations in the Active Set is few in real network, receive that in first base station data and the signaling of required transmission also can't be a lot of between second base station and first base station under the situation of ropy packet so.And common first base station has the good channel quality, it receives that the probability of the measured packet of matter is bigger, that is to say that uplink macro diversity processing method in most of the cases provided by the present invention can not increase the load of any data and signaling to network, like this under average level, the present invention has reduced required information transmitted amount between first base station and second base station, thereby has increased the capacity of system.
