Description
Technical field
The present invention relates to the communications field, in particular to a kind of collocation method and the device of measuring interval.
Background technology
Operator's networking cost is saved while the high-quality service of cheap rate is provided to user, more efficiently utilize Internet resources, propose one-stop radio access scheme, introduce the radio reception device that one is called Home eNodeB (Home NB or HeNB).This radio reception device can provide the function of various wireless access, user uses this equipment during in places such as family, market, company or schools, it is preferential that operator can provide on rate, can reduce the load that normal cells is also called macrocell, be a kind of well in-door covering optimization method simultaneously.
Some cell set that this Home eNodeB covers get married the overlay area of base station, front yard, some Home eNodeB only allows the access of the user through authorizing and provides service for these users, the community that this Home eNodeB covers is called non-public authorized user group (Closed SubscriberGroup, referred to as CSG) community.Corresponding, some Home eNodeB had both allowed the access of the user through authorizing and provided service for these users, allow again access without the user authorized and provide service for these users, the community that this Home eNodeB covers is called mixing (Hybrid) community.For mandate and undelegated user, the role that Hybrid serves as community is different, CSG cell being regarded as the user Hybrid community through authorizing, being regarded as open community (same to macrocell) for without the user Hybrid community of authorizing.
CSG cell is passed through at cell broadcast system messages block 1 (System InformationBlock 1, referred to as SIB 1) innerly carry CSG instruction and come to subscriber equipment (UserEquipment, referred to as UE) show that this community is a CSG cell, simultaneously each CSG cell non-public authorized user group # (CSG Identity, referred to as CSG ID) of having one to belong to.The CSG ID that each Hybrid community also has one to belong to.User terminal is according to whether supporting that CSG is divided into two classes, and a class supports the subscriber equipment (CSGUE) of CSG, and another kind of is the subscriber equipment (non-CSG UE) not supporting CSG.Have the advantage on rate due to CSG or Hybrid community, can alleviate again the load of macrocell simultaneously, CSGUE can as much as possible by authorized CSG or Hybrid community access network.Virtual network operator can retain a part of physical resource when the network planning, such as, physical layer identifications (Physical Cell Identity, referred to as PCI) special in CSG cell, and this configuration can not taken this part PCI resource by broadcast announcement to UE, Hybrid community.By the scanning of physical layer, UE can judge whether community is CSG cell.In addition, an optimum frequency allowed can be selected voluntarily to use when CSG or Hybrid community is set up, and the setting of CSG or Hybrid community is do not predict for macrocell.
PCI due to CSG or Hybrid community selects voluntarily when CSG or Hybrid community is set up in reserved scope, due to PCI resource limited (current each frequency only has 504), the PCI resource reserved to CSG or Hybrid community is little, when CSG or Hybrid community is disposed in a large number, in same macrocell coverage area, the probability that different CSG or different Hybrid communities use the situation of identical PCI to occur can be very high, and certain Hybrid community can not take the PCI resource of CSG cell.In order to address this problem, UE can by reading global cell identity (the Cell Global Identifier in CSG or Hybrid Cell Broadcast CB SIB1, referred to as CGI) distinguish a CSG or Hybrid community, because CGI is unique in public land mobile network (Public Land MobileNetwork, referred to as PLMN) scope.In addition, CSG cell only allows the access of the user through authorizing and provides service for these users, that is, CSG cell only has the UE of CSG ID belonging to this CSG cell to access in the CSG ID list (Allowed CSG Id List) allowed, therefore, for the connection control method based on UE, UE need read CSG cell broadcast SIB1 in CSG ID to do initial access control.
At universal mobile telecommunications system (Universal Mobile TelecommunicationsSystem, referred to as UMTS) in, CSG indication information is at information management entity (Management Information Base, referred to as MIB) middle broadcast, CGI and CSG ID broadcasts in MIB and SIB3/SIB4, therefore, for UMTS system, also need to read CSG/Hybrid Cell Broadcast CB and solve PCI conflict and initial Admission Control.
Fig. 1 is the schematic diagram of the scheduling mode of system message in the LTE system according to correlation technique, and as shown in Figure 1, the frame length of Long Term Evolution (Long-Term Evolution, referred to as LTE) system is 10 milliseconds (ms).MIB has the fixing transmission cycle of 40 milliseconds, and repeats in the #0 subframe of each radio frames of MIB within the transmission cycle to send.SIB1 has the fixing dispatching cycle of 80 milliseconds, SIB1 meets System Frame Number (System Frame Number, referred to as SFN) within dispatching cycle to be undertaken repeating to send by the #5 subframe (subframe numbering is from 0) that 2 divide exactly the radio frames of (SFN%2=0).
Fig. 2 is the schematic diagram of the scheduling mode of system message in the UMTS system according to correlation technique, and as shown in Figure 2, the frame length of UMTS system is 15slots, 10ms.MIB has the transmission cycle of fixing 8 frames (80ms), and the schedule information of SIB3/SIB4 can describe in MIB, adopts these parameters (SEG_COUNT=1, SEG_REP=32, SIB_POS=6) to illustrate for example here with SIB3.
This shows, MIB and SIB1 in LTE, the time location of the MIB in UMTS is relatively-stationary, and in other words, if know the time difference of abutting subdistrict and Serving cell frame boundaries, the time location of MIB and SIB1 of abutting subdistrict just can confirm substantially.Certainly, if the information of time difference is more concrete more detailed, the time location of MIB and SIB1 of abutting subdistrict is more accurate.If this time difference is specific to the time difference of parity frame in such as LTE, so the time location of the SIB 1 of abutting subdistrict just can determine.UE can by master sync signal (the Primary synchronizationsignal of search abutting subdistrict, be called for short PSS), auxiliary synchronous signals (Secondary synchronization signal, be called for short SSS) get the temporal information of abutting subdistrict, compare with the temporal information of Serving cell, obtain the time difference of the frame boundaries of abutting subdistrict and Serving cell, and can by this time difference informing network side.
UE correctly can solve MIB or SIB, the number of times reading MIB or SIB is needed to be indefinite, as can be seen from description above, if UE needs to read repeatedly MIB or SIB correctly could solve MIB or SIB, UE reads CSG/Hybrid Cell Broadcast CB needs the long time, if allow UE read voluntarily, larger impact can be caused to the business of UE, and network side is uncontrollable, therefore network side can configure special measurement interval (gap) to UE, UE is allowed to read CSG/Hybrid Cell Broadcast CB, this is measured interval and is different from current configuration to UE as alien frequencies, the measurement interval of isosystem measurement.
Because CSG/Hybrid community is densely distributed, network side is likely needed frequently to distribute the measurement interval of reading CSG/Hybrid Cell Broadcast CB to UE.For LTE, if UE needs to measure interval read MIB and SIB1, network side first configures to UE the measurement interval that is read MIB, after UE feedback measurement, the measurement interval that one is read SIB1 is configured again to UE, cancel the measurement interval of previously reading MIB simultaneously, wait UE again after feedback measurement, then cancel the measurement interval of reading SIB1.
Fig. 3 is the interaction diagrams of the configuration when pre-test interval according to correlation technique, and as shown in Figure 3, the method comprises following step S302 to step S314:
Step S302: UMTS Terrestrial radio access network (Evolved UMTSTerrestrial Radio Access Network, referred to as the EUTRAN)/UMTS of evolution sends Survey control message to UE.
Step S304:UE performs measurement after receiving Survey control message, and report measurement results is to EUTRAN/UMTS, and reporting information also comprises the PCI of adjacent area.
After step S306:EUTRAN/UMTS receives measurement result, when having judged that adjacent area is CSG/Hybrid community, there is PCI collision problem, or when needing UE to do initial access control to CSG cell, then sent the gap1 that MIB is read in configuration to UE.
Step S308:UE reads the MIB message of CSG/Hybrid community in gap1, and report measurement results is to EUTRAN/UMTS.
After step S310:EUTRAN/UMTS receives measurement result, send the message that the gap2 message of SIB 1 and the configuration of cancellation gap1 are read in configuration to UE.
Step S312:UE reads the SIB1 of CSG/Hybrid community in gap2, and report measurement results is to EUTRAN/UMTS.
After step S314:EUTRAN/UMTS receives measurement result, cancel the configuration of gap2.
Process as can be seen from Fig. 3 describes: the measurement interval of reading MIB and SIB1 is that serial is carried out, namely, network side waits until the gap2 that could read SIB after UE feedback reads MIB to UE configuration, cause whole process time delay very long like this, and space interface signaling is a lot, very large to the service impact of user.

According to embodiments of the invention, provide a kind of inking device measuring interval, this device may be used for the collocation method realizing above-mentioned measurement interval, this device comprises: configuration module, for configuring gap1 and gap2 to UE, wherein, gap1 is used to indicate the measurement interval that UE reads MIB, gap2 is used to indicate the measurement interval that UE reads SIB, and the time started of gap1 and the time started of gap2 are relatively independent.The time started of the relatively independent gap2 of referring to here can be arranged in effective duration of gap1, or the time started of gap2 is arranged on the end time of gap1, and wherein, effective duration is the time period between the time started to end time of gap1.Like this, UE gets started the SIB reading adjacent area in gap2 after can reading the MIB of adjacent area in gap1.
Wherein, MIB can be the MIB in LTE, or the MIB in UMTS, SIB can be the SIB1 in LTE, or SIB3 or SIB4 in UMTS.
As shown in Figure 6, in the layoutprocedure of configuration module, according to MIB and SIB1 in LTE, and the scheduling mode of MIB and SIB3/4 in UMTS, the gap of set form can be clearly set.Be 0 formatting that gap is described for the time difference of abutting subdistrict in LTE and Serving cell.The parameter of gap1, P can be arranged to a transmission interval of MIB, as 10ms, L can be arranged to a TTI, as 1ms, S can be arranged according to the transmitting time of adjacent area MIB.Gap2 can adopt the form identical with gap1, also can adopt the form not identical with gap1.If determine the parity frame time difference of abutting subdistrict and Serving cell, then can be arranged to form gap2 (a), P can be arranged to a transmission interval of SIB1, as 20ms, L can be arranged to a TTI, as 1ms, S can be arranged according to the transmitting time of adjacent area SIB; If only know that the frame time of abutting subdistrict and Serving cell is poor, then can be arranged to form gap2 (b), be identical form with gap1, and just the time started is different.
It should be noted that, if network side needs the system message reading multiple CSG/Hybrid community to UE configuration, said process can be repeated twice by network side, also can when configuring gap1 and gap2, consider the situation of multiple CSG/Hybrid community simultaneously, such as gap1 and gap2 form can allow UE can read the system message of this multiple CSG/Hybrid community simultaneously, or gives each a set of gap1 and gap2 of CSG/Hybrid cell configuration needing to read, i.e. many cover gap1 and gap2.
In sum, because CSG/Hybrid community is densely distributed, network side is likely needed frequently to distribute the measurement interval of reading CSG/Hybrid Cell Broadcast CB to UE, if the measurement interval of reading MIB and SIB is undertaken by Signalling exchange serial, whole process time delay is very long, and space interface signaling can be a lot, very large to the service impact of user.By embodiments of the invention, the duration of UE reading system message of target cell process can be shortened, reduce the space interface signaling measuring interval configuration simultaneously, reduce the impact on business, promote the business experience of user.
