Respectively the CRRM unit is carried out point-load control, concentration power control, concentrates the specific implementation of switching controls to be described below.
At first, to the loading condition of CRRM unit according to each single system communication network in the multi-standard communication network, the specific implementation that control terminal inserts is described.The CRRM unit mainly carries out point-load control aspect three, be respectively forward loading centralized control, reverse load centralized control and the control of access channel load centralization.
Forward loading is used to detect forward pilot power, can control terminal inserts and receive the pilot signal of other standard networks from other standard communication networks.In the forward loading centralized control, certain single system communication network in the multi-standard communication network is that terminal is set up before the calling, the radio resource managing unit of this single system communication network detects the forward loading situation of this single system communication network earlier, signal to noise ratio Ec/Io as forward pilot, if the forward loading of this standard communication network is heavier, for example Ec/Io is higher than set point, then this radio resource managing unit sends request to the CRRM unit, and reporting current forward loading information, request CRRM unit is that terminal is selected the lighter single system communication network of forward loading.After CRRM receives request in the unit, determine the standard that terminal can be supported, determine then the terminal support and forward loading be lighter than a kind of communication network of standard of the single system communication network of the request of initiation, the notice terminal inserts this single system communication network, being the current single system communication network that should insert of terminal, is that terminal is set up calling by this single system communication network.The CRRM unit can be except that the single system communication network of initiating request, select a kind of communication network of standard in the standard of terminal support at random according to network condition, also can select a kind of communication network of standard according to the selecting sequence that setting principle is determined, the forward loading of the single system communication network that the forward loading and the initiation of this single system communication network are asked compares then, if the former is lower than the latter, then control terminal inserts the lighter single system communication network of forward loading, for example, the single system communication network that CRRM unit notice forward loading is lighter sends the paging indication to terminal, so that terminal inserts this single system communication network; Otherwise the CRRM unit continues to select a kind of communication network of standard to carry out forward loading relatively, inserts for terminal until determining the lighter relatively single system communication network of forward loading.If the forward loading of the communication network of all standards that terminal is supported is all heavier, then this access failure.The CRRM unit also can carry out disposable comparison to the forward loading of the communication network of all standards of terminal support, therefrom selects the lightest single system communication network of forward loading and inserts for terminal.Like this, by the CRRM unit load of each single system communication network in the multi-standard communication network is weighed, control terminal inserts load lighter single system communication network relatively, with the load of each single system communication network of balance.
The reverse load centralized control is that the access that inserts is controlled, and is used to detect reverse access, and can final terminal insert the situation that depends primarily on reverse load.In the reverse load centralized control, before certain single system communication network in the multi-standard communication network accesses terminal, the radio resource managing unit of this single system communication network is the reverse load situation of this single system communication network earlier, as reverse signal intensity indication (Received SignalStrength Indication, RSSI), the number of users more (or user rate is bigger) or the suffered interference of this single system communication network sub-district of the big more explanation of RSSI are bigger, be that reverse load is heavier, this radio resource managing unit sends request to the CRRM unit then, and reporting current reverse load information, request CRRM unit is that terminal is selected the lighter single system communication network of reverse load.After CRRM receives request in the unit, determine the standard that terminal can be supported, determine then the terminal support and reverse load be lighter than a kind of communication network of standard of the single system communication network of the request of initiation, the notice terminal inserts this single system communication network, be the current single system communication network that should insert of terminal, insert this terminal by this single system communication network.The CRRM unit can be except that the single system communication network of initiating request, select a kind of communication network of standard in the standard of terminal support at random, also can select a kind of communication network of standard according to the selecting sequence that setting principle is determined, the reverse load of the single system communication network that the reverse load and the initiation of this single system communication network are asked compares then, if the former is lower than the latter, then control terminal inserts the lighter single system communication network of reverse load, for example, notifying reverse load lighter single system communication network in CRRM unit sends the paging indication to terminal, so that terminal inserts this single system communication network; Otherwise the CRRM unit continues to select a kind of communication network of standard to carry out reverse load relatively, inserts for terminal until determining the lighter relatively single system communication network of reverse load.If the reverse load of the communication network of all standards that terminal is supported is all heavier, then this access failure.The CRRM unit also can carry out disposable comparison to the reverse load of the communication network of all standards of terminal support, therefrom selects the lightest single system communication network of reverse load and inserts for terminal.Like this, by the CRRM unit load of each single system communication network in the multi-standard communication network is weighed, control terminal inserts load lighter single system communication network relatively, with the load of each single system communication network of balance.
Access channel is used for reverse link, and support call initiation, page response, command messages, registration and Short Message Service etc., terminal use the random access protocol of time slotization to insert.Access channel has very high throughput in some cases, because the existence of turn-on channel transmitting power open loop control, a large amount of terminal access communications network simultaneously can produce bigger interference at reverse link, finally causes the increase of sub-district received power and the minimizing of reverse chain-circuit capacity.
The purpose that CRRM inserts the unit load centralization control is in time to find the access load abnormal situation of certain single system communication network, and the access parameter that terminal inserts the concrete single system communication network in the multi-standard communication network controlled and adjust, make terminal can normally insert the single system communication network of its support, improve the access rate of terminal, guarantee the capacity of each single system communication network simultaneously.Inserting load centralization control is the average time delay that continues of the trial that control terminal inserts request in access procedure, is used for adjusting the blanking time of access, can also control the code rate of access etc.Exactly, inserting load centralization control should be to inserting parameter control and adjustment.
In the control of access channel load centralization, load information and access parameter information that the CRRM unit reports according to the radio resource managing unit of each single system communication network, determine that certain single system communication network enters the high load condition that inserts, at this moment, CRRM unit may command terminal realizes inserting in this terminal single system communication network that support, that load is lighter relatively, for example, notifying reverse load lighter single system communication network in CRRM unit sends the paging indication to terminal, so that terminal inserts this single system communication network, and in this single system communication network, realize inserting.If the access of each the single system communication network in multi-standard communication network load is all very high, then the CRRM unit is adjusted the access parameter of single system communication network according to the load information of single system communication network, as reduce access rate, thereby reduce the access channel load, improve under the high access load of the multi-standard communication network abnormal conditions, the access success rate of terminal makes multi-standard communication network more stable.After the access load of the single system communication network in the multi-standard communication network reduced, the CRRM unit can return to the access parameter of this single system communication network the access parameter that inserts under the load normal condition.Access parameter can be average time delay, access rate, the coded system etc. of continuing of the request of access.
Secondly, the CRRM unit is described according to the specific implementation that the loading condition of each single system communication network in the multi-standard communication network carries out the exterior ring power fine setting.
The FER of carrier frequency forward direction is used to describe speech quality, if the FER height illustrates that then communication quality is bad; If FER is low, illustrate that then speech quality is good.When FER is high, can improve the access thresholding, communication network improves speech quality by the access of limiting terminal; When FER hangs down, can reduce the access thresholding, under the prerequisite that guarantees communication quality, allow more terminal access communications network.The access thresholding is used for control terminal access communications network, when promptly the access of terminal is higher than the access thresholding, allows terminal access communications network, when the access of terminal is lower than the access thresholding, and refusal terminal access communications network.
Fig. 4 is that the FER flow chart is adjusted in the CRRM unit in the embodiment of the invention three, and as shown in Figure 4, the concrete processing procedure that FER is adjusted according to the loading condition of each single system communication network in the multi-standard communication network in the CRRM unit may further comprise the steps:
Step 401～step 402: the base station in certain single system communication network reports the FER set point to radio resource managing unit, after radio resource managing unit is received the FER set point, reports the FER set point to the CRRM unit.
After step 403:CRRM receives the unit FER set point,, the FER set point is adjusted, returned adjusted FER set point to radio resource managing unit then according to the loading condition of each single system communication network in the multi-standard communication network.
Step 404: after radio resource managing unit is received adjusted FER set point, return adjusted FER set point to the base station.
Because transmitting power is excessive, can cause interference to other single system communication networks, therefore, further, the transmitting power thresholding can be adjusted according to adjusted FER notice terminal in the base station, after terminal is notified, the transmitting power thresholding is adjusted, made this single system communication network in the reasonable scope the interference of other single system communication networks.
Once more, concentrate the specific implementation of switching controls to be described the CRRM unit according to the load state of each single system communication network in the multi-standard communication network.
Can realize that by the CRRM unit that is provided with in the multi-standard communication network alien frequencies between each single system communication network switches in the multi-standard communication network, can realize by pilot beacon technology or direct handoff technique.
The pilot beacon technology is meant that the frequency of certain the single system communication network A in the multi-standard communication network is F1, the frequency of another single system communication network B is F2, because terminal is to the problem of alien frequencies ionization meter, for avoiding terminal to switch to the blindness of B by A, during the network planning, the configuration pilot tone F1 identical in B with A, but pilot tone F1 only has common signal channels such as pilot channel, without any Traffic Channel, the F1 that disposes among the B is called pseudo-target standard pilot tone or pilot beacon.Among the B, because pilot tone F1 is identical with the pilot tone coverage of F2, therefore, terminal can be known the pilot frequency intensity of F2 more exactly by the measurement to pilot tone F1, with the accuracy that guarantees to switch.A and B can be the single system communication network of identical standard, different frequency.If terminal resides among the A, when the CRRM unit determines that according to the loading condition of A and B the terminal needs switch to B by A, can make terminal switch to B by the pilot beacon technology by A.
Directly handoff technique is meant when the CRRM unit determines to determine that according to the loading condition of each single system communication network in the multi-standard communication network terminal needs switch, for example, terminal is switched to B by A, base station control unit disconnection among the CRRM unit controls A is connected with terminal, indicate base station control unit and terminal among the B to connect then, realize the switching of terminal by A to B.Described base station control unit can realize in radio resource managing unit.
In sum, in the scheme that various embodiments of the present invention provide, in multi-standard communication network, introduced the CRRM unit, realization is carried out unified management to the Radio Resource of multi-standard communication network, grasp the loading condition and the system operation situation of multi-standard communication network comprehensively, realized real-time control and unified optimization, farthest utilized the Radio Resource of multi-standard communication network the multi-standard communication network Radio Resource.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
