Description
Technical field
The present invention relates to wireless communication technology, refer to a kind of Radio Resource control method and system especially.
Background technology
Communication between the person to person (H2H, Human to Human) is that the people passes through operation of equipment is realized, the existing wireless communications technology is based on that the Communication Development of H2H gets up.And the sense stricto definition of machine (M2M, Machine to Machine) is the communication of machine to machine, and sensu lato definition is the application and the service of core, networking with the machine terminal intelligent interaction.M2M is based on the intelligence machine terminal, is the access means with multiple communication mode, is the informatization resolve scheme that the client provides, and is used to satisfy the information system requirement of client to aspects such as monitoring, command scheduling, data acquisition and measurements.
The development of wireless technology is the key factor of M2M market development; It has broken through the space-time restriction and the region obstacle of traditional communication mode; Make the enterprise and the public break away from the cable constraint, let the client more effectively control cost, reduce mounting cost and easy to use.In addition, growing demand is promoting M2M and is constantly advancing.Yet constantly increase with information processing capability and the network bandwidth and conflictingly to be; The means that information is obtained lag far behind, and M2M has well satisfied this demand of people, through M2M; People can monitor external environment condition in real time, realize on a large scale, the information gathering of automation.Therefore; The application of M2M comprises sector application, domestic. applications, individual's application etc.; Wherein, Sector application comprises traffic monitoring, warning system, rescue at sea, automatic vending machine, driving paying etc., and domestic. applications comprises automatic data logging, temperature control etc., and the individual uses and comprises life detection, far-end diagnosis etc.
The object of M2M is machine, Human-to-Machine, and the data communication between one or more machines is defined as machine class communication (MTC, Machine Type Communication), lessly in this case needs human-computer interaction.The machine of participating in MTC is called MTC equipment or MTC terminal (MTC Device).MTC equipment can pass through public land mobile communication network network (PLMN, Public Land Mobile-communication Network) and communicate with other MTC equipment or MTC server.
After introducing MTC and using, can carry out some optimizations to existing communication system, satisfying the MTC application demand, and the domestic consumer terminal in the existing network (UE, User Equipment) do not exerted an influence according to its characteristics.Some distinguishing features that M2M uses have: the MTC number of devices is a lot, and each data quantity transmitted is little, and transmission intercal is big, part MTC device location relative fixed.According to statistics, the MTC equipment of in the cell range in certain urban district, installing will reach 3000, if the initiation that so many MTC equipment is relatively concentrated inserts at random, such as under situation such as fire, earthquake, reporting to the police simultaneously, will bring very big impact to network.Usually, a plurality of base stations can be connected to same core network element, like Mobility Management Entity (MME; Mobility Management Entity); When the numerous MTC equipment in all base stations all needed access network, for example after the outage, MTC equipment all when restoring electricity need be registered in the network; To cause MME to bear huge signaling and impact, even possibly cause overload.
During numerous MTC equipment access network, with taking a large amount of Radio Resources.If the MTC number of devices of access network is too many, will cause the Radio Resource overload, this will produce adverse influence to common H2H equipment access network.Because for any one sub-district; Radio Resource is limited (confirming in other words conj.or perhaps); At Long Term Evolution (LTE; Long-Term Evolution) in the system; Radio Resource can be used Physical Resource Block (PRB; Physical Resource Block) expression; Agreement stipulates that continuous
number of sub-carrier is defined as a PRB (up) in
individual single-carrier frequency division multiple access (SC-FDMA) symbol continuous in the time domain and the frequency domain; Wherein,
is the SC-FDMA symbolic number that comprises in the ascending time slot, and
is the resource block size on the frequency domain.The ascending resource of whole sub-district can be expressed as by
number of sub-carrier to be formed; Wherein, The value of
is by the uplink bandwidth decision of disposing in the sub-district; Satisfy
wherein simultaneously; Minimum uplink bandwidth
and maximum uplink bandwidth
agreement define the downlink physical Resource Block;
individual continuous OFDM (OFDM) symbol is defined as a Physical Resource Block (descending) with
individual continuous subcarrier in frequency domain on the time domain; Wherein,
is the OFDM symbolic number that comprises in the descending time slot, and
is the resource block size on the frequency domain.The downlink resource of whole sub-district can be expressed as by
number of sub-carrier to be formed; Wherein, The value of
is by the downstream transmission bandwidth decision of disposing in the sub-district, and
of agreement support now also is between 6 to 110.Too many when the MTC number of devices that inserts the sub-district, will inevitably take a large amount of Physical Resource Block, the Physical Resource Block limited amount that causes domestic consumer to use has influenced the efficiency of transmission of domestic consumer's access network.
In existing protocol; Some measurements need be carried out in the base station; So that according to enforcement access control of the change dynamics of load etc.; The measurement of existing base station comprises the throughput that use, the quantity of activated terminals, the terminal of PRB is total etc.; Wherein, the use of PRB comprises that total Physical Resource Block (Total PRB usage) of use, the Physical Resource Block (PRB usage per traffic class) that each grade of service is used, the Physical Resource Block (PRB usage for SRB) that Signaling Radio Bearer uses, the Physical Resource Block that CCCH uses comprise uplink and downlink (DL PRB usage for Common Control Channels, UL PRB usage for Common Control Channels).
The measurement to PRB has been realized in existing base station, such as:
For the total Physical Resource Block that uses; Protocol definition is that (this section period is also referred to as Measuring Time) average total Physical Resource Block ratio
that uses is wherein in the duration T; M1 (T) is meant the Physical Resource Block summation of transmission that uplink and downlink are useful on, and P (T) is meant Physical Resource Block total in the duration T;
The Physical Resource Block that each grade of service is used is defined as
wherein; M1 (qci; T) be meant total Physical Resource Block that each grade of service is used in the duration T, P (T) is meant Physical Resource Block total in the duration T.Each grade of service is according to QoS Class Identifier (QCI here; QoS Class Identifier) divide, QCI is used to specify the control of definition in the access node to carry a level packet forward mode (like dispatch weight, admit thresholding, queue management thresholding, link layer protocol configuration etc.);
Physical Resource Block and above-mentioned two kinds of definition that Physical Resource Block that Signaling Radio Bearer uses and CCCH use are similar, repeat no more here.
Yet what the surveyingpin of existing base station was right is all terminals, and the base station can not know that H2H equipment uses the situation of Radio Resource, thereby can not prevent effectively that the machine kind equipment from taking the appearance of the situation of a large amount of Radio Resources.Like this,, possibly hinder the access of domestic consumer, have a strong impact on the access impression of domestic consumer if the machine kind equipment quantity of access network is huge.

According to the method that first embodiment describes, base station 1 provides enough Radio Resources for H2H equipment, has avoided H2H equipment the problem that access delay is big, efficiency of transmission is low to occur.
Second embodiment supposes in long evolving system, and MTC equipment and H2H equipment are through base station 2 jurisdiction districts, 2 access networks and be in connection status.In order to realize load balancing; Base station 2 needs to measure in real time the operating position of Radio Resource; The operating position of present embodiment middle finger PRB comprises total Physical Resource Block (Total PRB usage) of use, the Physical Resource Block (PRB usage per traffic class) that each grade of service is used etc.
In a second embodiment; Suppose that MTC equipment and H2H equipment all can initiate the business of the business of permissible delay (Delay tolerant) business of time delay tolerance (or be called) or low priority; Corresponding with it is, the initiation that MTC equipment and H2H equipment also can initiate to set in business such as the existing protocol of business or normal priority of permissible delay not is former because the signaling that initiate at the terminal is called out the business of the data call (mo-Data) of (mo-Signaling) or terminal initiation.And, under some scene, when detecting emergency, can also initiate the business (high Priority Access) of high priority like MTC equipment in the monitoring state.H2H equipment can be initiated the business and the urgency traffic (emergency) of high priority.Urgency traffic is a kind of business of limit priority, is meant that terminal and local urgency communication accept center such as police, fire alarm, medical aid etc. and communicate.
Suppose that base station 2 is provided with the professional operable PRB threshold value of permissible delay in advance, the Radio Resource control method comprises in this enforcement:
Base station 2 measurements are initiated the total PRB that uses at the professional terminal of permissible delay and are initiated not total PRB of the terminal use of permissible delay business;
Whether the PRB that the professional actual use in terminal of permissible delay is relatively initiated in base station 2 reaches the threshold value that is provided with in advance; If reach; The permissible delay of the terminal initiation that then base station 2 refusals are new is professional; Perhaps base station 2 selects part to initiate permissible delay professional MTC equipment or H2H equipment, and the RRC that discharges this part terminal connects, so that effectively the employed stock number of permissible delay service terminal is initiated in control.
In addition, if the PRB that base station 2 is found to initiate to use at the professional terminal of permissible delay above threshold value, can also further reduce the scheduling to these terminals,, reduction in time uses Physical Resource Block so that initiating the professional terminal of permissible delay.
Other implementations of second embodiment can also be:
Base station 2 is measured the employed PRB of service with different priority levels respectively; Base station 2 is set the PRB threshold value that service with different priority levels can be used simultaneously; When the PRB of certain priority service use reaches the threshold value of setting; The foundation request of this priority service of base station 2 refusals, perhaps release portion has been initiated the terminal of this priority service; Perhaps,
Base station 2 is measured total PRB of the terminal use of different priorities respectively; Base station 2 is set the PRB threshold value that the terminal of different priorities can be used simultaneously; When the PRB that uses when the terminal of certain priority reaches threshold value; The accessing terminal to network of base station 2 these priority of refusal, the perhaps terminal of having inserted of this priority of release portion.Need to prove; Self affiliated precedence information (terminal that comprises low priority is preserved at the terminal; The terminal of normal priority and the terminal of high priority); When initiating service request, need send to base station 2, the Physical Resource Block that use according to all these priority endpoint of this information measurement base station 2 through the priority of RRC signaling under with self; Perhaps,
Base station 2 is measured total PRB of the terminal use of (Group) not on the same group respectively; Base station 2 is set the PRB threshold value that can not use on the same group simultaneously; When the PRB of certain group use reaches threshold value; Base station 2 refusals are under the jurisdiction of the accessing terminal to network of this group, perhaps release portion or whole terminal that has been under the jurisdiction of this group.Need to prove; Different terminal can be under the jurisdiction of different groups; Also can be under the jurisdiction of same group, each group all has group name sign separately, and the group name that it is subordinate to is known through terminal transmission RRC signaling in base station 2; Perhaps know that through core net its group name that is subordinate to is (concrete when passing through core net and knowing that its group name that is subordinate to is meant that core net is carried out authentication to the terminal of inserting; Know the group name that it is subordinate to, the group name that is subordinate to by this terminal of core net informing base station then), and then can measure the PRB that does not use on the same group respectively; Perhaps,
