Present application for patent is advocated the 60/651st of being entitled as of application on February 8th, 2005 " Method andApparatus forAllocatingResources in a Multicast/Broadcast Communications System ", the priority of No. 395 provisional application cases, described provisional application case transfers the assignee of the application's case and clearly is incorporated herein by reference.
Technical field
The present invention relates generally to a kind ofly has the cordless communication network that a plurality of potential mobile subscriber equipments (UE) and base station group communicate, and more particularly, relates to the multicast/broadcast communication in this type of network.
Background technology
Figure 1A illustrates exemplary wireless communications network.Group of user equipment (UE wherein one is marked as 20) (wherein some or all subscriber equipmenies all can be mobile) is communicated by letter with base station group (wherein being marked as 26).At any given time, each UE 20 uses a certain channel (a, b, c or d) to communicate by letter with base station 26.As used herein, channel comprises that frequency or communication link are in order to promote the layout of communication.For instance, in some system, channel comprises two communication links, the frequency that its each use is independent.In Figure 1A, UE 20 can transmit to base station 26 by first frequency, and can second frequency 26 receives from the base station.This constitutes channel to communication link.Each base station 26 can be configured to provide service on one or more channels, and each UE 20 can be configured to the service that receives on one or more channels.
Use and high quality-of-service is provided in order to optimize Internet resources, UE 20 can be maintained roughly evenly in the channel assignment configuration of issue.That is to say that communication traffic load is able to roughly balance between the available channel on the available base stations.For under the dynamic environment of frequent UE communication link foundation and end and frequent variations (wherein base station current just serving indivedual mobile UE) keep the load of balance, each base station 26 is configured to broadcast certain network status information to UE, and each UE is configured to monitoring network state information and monitor communication link quality parameter, and comes selective channel and base station based on described information and described parameter.The process of the channel that selection is used to serve can be described as channel and selects, and selects the process of a certain base station transceiver that is used to serve to can be described as cell selecting or sub-district gravity treatment.
Developed some standard, and current this Dynamic Selection of management and the reuse adoption process used it for.This class standard is the sub-district gravity treatment of 3GPP1999 (R ＇ 99) version.According to R ＇ 99 sub-district gravity treatments, broadcast a certain network state information.For instance, system information block (SIB) 3, SIB 4, SIB11 and SIB 12 data are used for the sub-district gravity treatment through broadcasting for UE.In addition, the SIB data can be used for calculating some cell parameter (for example Qoffsets, n, Qhysts, Qhcss and Qmeass), and described parameter also is used for the sub-district gravity treatment.As the part of channel and/or cell selecting, UE also can carry out the channel quality test according to institute's accepted standard, and described standard for example is the Operability Testing of 3GPP TS 25.304 aspects.In order to minimize unnecessary gravity treatment behavior, R ＇ 99 reselection algorithm tend to have a preference for current channel and sub-district.This tendency is called as viscosity.
For instance, in the network of Figure 1A, UE 20 is mobile phones, and wherein initial, reception of user and termination telephone are called out when driving.Along with indivedual UE away from current serving BS, the signal weaker that is associated with current channel.UE monitors the SIB data, and carries out R ＇ 99 sub-district gravity treatments.As the part of R ＇ 99 sub-district gravity treatments, UE determines just whether the new channel by the service of new sub-district is suitable, and communicates by letter on the new channel of beginning in new Serving cell.When UE gravity treatment channel and sub-district, keep required distribution by reselection algorithm.Because high activity tends to reduce the quality of channel and sub-district, and described algorithm is partial to select the channel and the sub-district of better quality, so during gravity treatment, UE more likely selects to have channel and the sub-district than the low communication business.Therefore, the business in the network tends to reach balance.
Except two-way communication, the network shown in Figure 1A can be used for broadcast service equally.This type of service is that point is to multiple spot multimedia broadcast/multi broadcast service (MBMS).In this type of broadcasting, the UE of customized described service is from the notice of current service cell reception about broadcasting on the horizon, for example result of football match today.Described notice contains will be in the information on which channel relevant for described broadcasting.Its user want to participate in described broadcasting UE be tuned to correct channel, and receiving broadcasting information.The result of broadcasting is that the UE of potential greater number accumulates on the same channel.
Figure 1B shows the figure from base station group (wherein being marked as 26) wireless receiving broadcast data of the exemplary UE group (wherein being marked as 20) accumulate on the individual channel a.During normal running, this type of gathering will make network overload, because network does not have on individual channel in order to serve the ability of so big UE group.Yet during broadcasting, this gathering can not make network overload, because each UE can receive mass data, but only launches the data of minimum, and broadcast data accumulates on the single common signal channel, rather than consumes the single resource of each UE that is used for described gathering.Base station 26 broadcast data on published channel, and each UE 20 receives data on described channel.
Yet after off-the-air, UE will get back to normal transmission levels, and the gathering that concentrates on the described individual channel a can make the Internet resources overload.This can be avoided by evacuation command is broadcast to UE substantially, and described UE comes described evacuation command is responded by channel and the sub-district selecting to be used to serve.The result of this evacuation will be, UE moves to different channels, and to be similar in the sub-district that the distribution shown in Figure 1A quarters at those channels of service, and wherein UE is distributed between the sub-district on each channel a, b, c and the d.
Therefore, need to make in this technology UE can with effective and simple mode in response to evacuation command on channel " evacuation ", in this way, final load is able to balance on channel and sub-district.

Embodiment
This paper makes word " exemplary " refer to " serving as example, example or explanation ".Any embodiment that is described as " exemplary " herein should be interpreted as must be more preferred or favourable than other embodiment.
Below describe in detail at some specific embodiment of the present invention.Yet, can implement the present invention by many different modes.In this described, referring to accompanying drawing, wherein same parts was represented by same numbers all the time.To from following description, see easily, can in the device of any system that is configured to promote the telecommunication between multiple arrangement or this type systematic, implement described embodiment.
Discuss as mentioned, need a kind of mechanism, its in order to when many these type of UE are clustered on the same channel (for example, in the end of MBMS point) to multipoint session subscriber equipment (UE) or distant station are evacuated on channel.Before evacuating, network UE channel and sub-district distributional class are similar to the distribution shown in Figure 1B, and UE concentrates on the same channel a significantly.The result of this type of evacuation shows in Figure 1B, and wherein UE is distributed between the sub-district on each channel a, b, c and the d.
Fig. 2 be describe wherein to small part based at random or the pseudorandom selection algorithm carry out the flow chart of the embodiment that evacuates.At step 102 place, UE receives evacuation command from current service cell.At step 104 place, be instructed to use at random or pseudo-random function (being called hash function) to carry out each UE that evacuates, its result roughly is evenly distributed on the output valve of certain limit, to select candidate channel between available channel.Should be appreciated that actual function is determined by the UE embodiment, is roughly uniform as long as its value distributes.
In certain embodiments, available channel only comprises current just by current service cell or by the channel of adjacent cell service, wherein adjacent cell comprises the sub-district of contiguous current service cell, and in certain embodiments, available channel also can comprise other sub-district that UE can communicate by letter with it.For instance, when receiving the MBMS broadcast singal, UE monitors the channel that can use with current service cell.In certain embodiments, the other supervision of the UE channel that can use with adjacent cell.In certain embodiments, available channel can only comprise the channel that it is existed potential Serving cell more than.UE then uses described available channel to come selective channel together with hash function.Each UE uses hash function to come the result of selective channel to be, described UE is dispersed in the channel randomly with the distribution of general planar.
For instance, during broadcasting, by monitoring the channel condition information from its current service cell and adjacent cell, UE can determine that it has 10 available channels, and it is numbered 1 to 10.After receiving evacuation command, in order to select a channel as candidate channel, UE uses hash function, and described hash function adopts many possible input values, and distributes with general planar it is mapped to possible output valve (being channel number 1 to 10 in this example) than peanut.Described hash function can (for example) use the part of 10 figure place telephone numbers or 10 figure place telephone numbers as input one group of mathematical function to be carried out in described input, and exports with the integer that roughly the same possibility produces in the scope 1 to 10.To understand, any constant different with the analog value of other UE or variable UE value (for example User Recognition, GPS position or any other value) can be used as the hash function input.Selecting channel as candidate channel in step 104 is that channel corresponding to the output integer of hash function.
In the step 106 of Fig. 2, UE selects service channel and Serving cell based on selected candidate channel to small part.In one embodiment, UE uses selected candidate channel to camp on current service cell (for example, transmitting the sub-district of the MBMS broadcasting that is received).Perhaps, UE can come to the available cell graduation of serving selected channel based on communication link parameter to small part, and camps on the sub-district with highest ranking.In certain embodiments, UE is the test of executive communication link-quality before being stationed, for example the sub-district Operability Testing of 3GPPTS 25.304 aspects.In certain embodiments, UE carries out sub-district gravity treatment (for example R ＇ 99 gravity treatments) based on selected candidate channel.
The favourable aspect of carrying out the channel selection with hash function is that it has guaranteed uniform evacuation in fact.That is to say that the initial condition that accumulates on the same channel with many UE wherein is opposite, the result who evacuates with hash function is that UE is evenly distributed between available channel widely and roughly.This help by after off-the-air on each channel balance UE load and avoid making Internet resources overload.
Fig. 3 is that wherein UE determines to quarter at the flow chart of the embodiment on which sub-district by monitored cells data before being stationed.At step 202 place, UE receives evacuation command from current service cell.At step 204 place, be instructed to select candidate channel to carry out the UE that evacuates.UE can select candidate channel according to the method for describing referring to Fig. 2 that is used for selective channel or by other method.For instance, select candidate channel can to small part based on function with the output distribution except that smooth.Can determine the feature of described distribution by the channel characteristics that (for example) monitored before or after the reception evacuation command.For instance, which channel UE can monitor by current or neighbor cell service, and is weighted by each to described channel of the number of Serving cell.In certain embodiments, get rid of the channel of serving by the sub-district that is less than preset minimum number.
At step 206 place, UE selects candidate cell, but do not camp on described candidate little on.UE can select the method for sub-district or select candidate cell by other method according to being used to of describing referring to Fig. 2.For instance, UE can be a plurality of cell monitoring communicating link datas (for example selecting parameter).UE can follow according to the comparative result of the communicating link data relevant with each sub-district and select candidate cell.In certain embodiments, select the top sub-district of described sub-district or sub-district son group as candidate cell.In other embodiments, can between available cell or available cell group, select candidate cell at random.
At step 208 place, UE monitors communication link data, for example candidate channel and candidate cell intensity and mass parameter.These type of data can be included in the 3GPP TS 25.304 aspects parameter relevant with applicability and the parameter relevant with 99 editions sub-district gravity treatments of ＇, for example SIB3/4 and SIB11/12 or another standard, non-standard or proprietary cell selecting method.These type of data also can comprise other parameter of can be in addition or monitoring with alternative.In one embodiment, UE be tuned to selected channel on the selected sub-district.Under the situation that does not camp on selected sub-district, UE monitors whether selected channel can be accepted with definite described sub-district, or the SIB3/4 and/or the SIB11/12 parameter that read on the candidate cell are carried out 99 editions sub-district gravity treatments of ＇ with preparation.
At step 210 place, the parameter that UE is based, at least in part, on the supervision of step 208 place camps on a sub-district.In an one exemplary embodiment, at step 208 place, UE is not camping under the situation of candidate cell monitoring data and is determining whether described sub-district can be accepted.At step 210 place, UE then camps on candidate cell.Perhaps, at step 208 place, UE determines that described sub-district is unacceptable, and collects SIB3/4 and SIB11/12 parameter once more under the situation of not being stationed.At step 210 place, UE then uses 99 editions rules of ＇ to carry out the sub-district gravity treatment.In certain embodiments, use from current service cell be not the parameter value of candidate cell 99 editions cell reselection procedures of ＇ of being used for carrying out gravity treatment from candidate cell may be gratifying.In this type systematic, the parameter that reads SIB3/4 for example and/or SIB11/12 at candidate cell will there is no need to prepare being used for carrying out 99 editions sub-district gravity treatments of ＇ from candidate cell, but can carry out.In some cases, the sub-district gravity treatment also will comprise channel reselection.
Test channel or carry out being aspect gravity treatment favourable the communication service that can avoid unnecessary from candidate cell before being stationed.Candidate cell may be because (for example) be used for communication unsatisfactorily from the noise of other UE or external environmental source.Thus, be camping directly on candidate cell and will cause instant gravity treatment except that re-selecting cell.By testing before being stationed or gravity treatment, UE can avoid being stationed, instant gravity treatment and camp on new channel and sub-district once more.
Can various combinations and arrange and implement in above-mentioned various aspect.Figure 4 and 5 are flow charts of two exemplary arrangements of the described aspect of explanation.The technical staff in described field will recognize, the combination of the others of carrying out with other order also is possible.
Fig. 4 is the flow chart of an one exemplary embodiment.At step 402 place, UE receives evacuation command from current service cell.At step 404 place, carried out the UE pseudorandom ground of evacuating and select candidate channel by instruction.UE can (for example) select candidate channel according to hash function, and it is from by current service cell or by pseudorandom ground selective channel between the available channel of neighbor cell service.In certain embodiments, use the another kind of method of selecting candidate channel.
At step 406 place, UE selects candidate cell, but does not camp on described candidate cell.UE can select candidate cell according to the comparative result of the communicating link data relevant with each available cell.In certain embodiments, select the top sub-district of available cell or available cell son group (for example adjacent cell) as candidate cell.In other embodiments, can between available cell or available cell group, select candidate cell randomly.
At step 408 place, read the selection parameter relevant if UE is not programmed with candidate channel and candidate cell, UE moves to step 412 so.In certain embodiments, it may be unnecessary reading specific selection parameter, because (for example) known all available cell have identical or roughly the same selection parameter value, or because of fully reading the selection parameter of available cell recently and it being stored for calling again.This type of programming can (for example) be determined by user, ISP, or can be determined based on the network parameter that is monitored.If it is necessary reading and selecting parameter, read the selection parameter at step 410 place so.This can (for example) by with UE be tuned on the candidate channel candidate cell but do not camp on described candidate cell and monitor and finish from the parameter of candidate cell reflector broadcasting.This can be extraly or comprises the signal quality parameter of the candidate channel on the monitoring and measuring candidate cell alternatively.These parameters can comprise and 99 editions sub-district gravity treatments of ＇ or the relevant parameter of another standard (for example dedicated cell choice criteria or non-dedicated cell choice criteria).At step 412 place, if use read at step 410 place or to determine to read at step 408 place in addition be that unnecessary available cell selects parameter to calculate extra cell selecting parameter.
For instance, UE may store the value of SIB3/4, and selects parameter S IB11/12 through programming to read.At step 410 place, do not camping under the situation of candidate cell, UE reads the SIB11/12 of candidate cell.At step 412 place, UE is based, at least in part, on the SIB11/12 parameter and the previously stored SIB3/4 parameter that read at step 410 place and calculates Qoffsets, n, Qhysts, Qhcss and Qmeass.
At step 414 place, to small part based on the cell reselection parameters storing, read and/or calculate carry out the sub-district gravity treatment.Can carry out the gravity treatment of described sub-district according to 99 editions sub-district gravity treatments of ＇ or any other cell selecting process.
Fig. 5 is the flow chart that some aspects have the one exemplary embodiment of another layout.At step 502 place, UE receives the evacuation command from current service cell.At step 504 place, be instructed to use previously described candidate channel system of selection or other method to select candidate channel to carry out the UE that evacuates.
At step 506 place, UE selects candidate cell, but does not camp on described candidate cell.UE can select candidate cell according to previously discussed candidate cell system of selection or other method.
At step 508 place, judge whether described candidate cell is satisfactory.For instance, but can carrying out acceptance, tests UE, for example the Operability Testing aspect 3GPPTS25.304.Also can carry out other test.This class testing can monitor signal strength signal intensity relevant with candidate cell and mass parameter, and judges based on special-purpose or non-application specific standard whether described sub-district is satisfactory to small part.If it is gratifying finding described sub-district, and if determine that at step 510 place gravity treatment is unnecessary, at step 512 place, UE camps on candidate cell so.Yet, if gravity treatment is necessary, as determining, if or find to carry out the sub-district gravity treatment so at step 514 place in described sub-district and unsatisfactory at step 508 place at step 510 place.The result of sub-district gravity treatment will comprise and camp in the gravity treatment of sub-district selected sub-district.
As discussed above, be understood by those skilled in the art that the order that can be different from the order that is disclosed among the particular exemplary embodiment discussed above is carried out the various operations of method described herein.For instance, be gratifying in case determine the sub-district, UE just can camp on described sub-district and not be chosen in and carry out the sub-district gravity treatment before being stationed.Perhaps, if the sub-district gravity treatment is necessary, UE can carry out or not carry out to test and judge whether candidate cell is satisfactory so.In certain embodiments, selecting candidate cell to occur in selects before the candidate channel.In certain embodiments, the sub-district gravity treatment can occur in and select before the candidate channel.Equally, can omit described various operation without departing from the invention and add other operation.
