Description

The connection control method of neighboring server and ProSe UE

Technical field

The present invention relates to the Access Control Technique of the communications field, particularly relate to connection control method and neighboring server (Proximity-basedServices, the ProSe) subscriber equipment (UserEquipment, UE) of a kind of neighboring server.

Background technology

At wireless communication field, along with the fast development that intelligent terminal and mobile Internet are applied, people are more and more higher to the requirement of Consumer's Experience and two-forty, big data quantity.Existing exist obvious limitation with base station for the cellular network of data transmission node center in the support of high data rate and adjacent service, under this requirement background, D2D (Device-to-Device, device-to-device) communication (namely described D2D the includes above-mentioned neighboring server ProSe communication) technology representing future communication technologies development new direction is arisen at the historic moment.The application of D2D technology, it is possible to the burden alleviating cellular network, the battery power consumption reducing subscriber equipment, raising data rate, and improve the robustness of network infrastructure, meet the requirement of above-mentioned high data rate traffic and adjacent service well.

D2D technology can be operated in mandate frequency range or unauthorized frequency range, allow multiple subscriber equipment (i.e. D2D subscriber equipment supporting D2D function, D2DUserEquipment, D2DUE) carry out when having network infrastructure or without network infrastructure directly find/directly communicating.The application scenarios of D2D mainly has three kinds:

UE1 and UE2 carries out data interaction under the covering of cellular network, and user face data is without network infrastructure, such as the pattern 1 of Fig. 1；Weak/without the UE relay transmission of overlay area, the pattern 2 in Fig. 1, it is allowed to the poor UE4 of signal quality pass through near have the UE3 of the network coverage and network to communicate, operator can be helped to spread over, improve capacity.

Earthquake or emergency are occurring, and when cellular network cisco unity malfunction, it is allowed to equipment room directly communicates, the pattern 3, UE5 in Fig. 1, between UE6 and UE7, chain of command and user face all carry out the data communication of a jumping or multi-hop without network infrastructure.

D2D technology generally includes D2D discovery technique and D2D communication technology:

D2D discovery technique refers to for judging/determine technology that is mutually adjacent (such as can carry out within D2D direct communications range) between two or more D2D subscriber equipment or that be used for judging/determining first user proximity of devices the second subscriber equipment.Generally, can finding the other side by sending or receive discovery signal/information between D2D subscriber equipment, under having cellular network to cover, network can assist D2D subscriber equipment to carry out D2D discovery；

D2D communication technology refers to that between D2D subscriber equipment, part or all of communication data can not be made directly the technology of communication by network infrastructure.

Neighboring server subscriber equipment ProSeUE is before carrying out D2D discovery or D2D communication, it is required for first obtaining corresponding Radio Resource, progress according to existing 3GPP standards meetings, no matter it is that D2D finds or the D2D communication resource, all there is the two spike-type cultivars method of salary distribution, namely based on competition resource acquisition (the first resource method of salary distribution) or by base station be UE distribute proprietary resource (the Secondary resource method of salary distribution) carry out D2D discovery/communication.The first resource method of salary distribution, generally by base station or one D2D resource pool of system predistribution, participates in the D2D ProSeUE finding/communicating and monitors this resource pool, and obtain D2D transmission resource by the mode competed.And the Secondary resource method of salary distribution is the ProSeUE suitable D2D resource of distribution by base station according to the request of ProSeUE.

Simultaneously, conclusion according to current 3GPP meeting, ProSeUE is when carrying out D2D discovery/communication and having data to need to send, in Secondary resource method of salary distribution situation, ProSeUE in the network coverage needs to enter connected state to carry out the application of resource, namely ProSeUE needs to access network, first resource method of salary distribution situation, and ProSeUE obtains resource according to requiring over competitive way.Under high load scenarios and/or high interference scene, in cellular network communication, it is carry out the Access Control under overload situations by ACB (restriction of AccessClassBarring access grade) and EAB (ExtendedAccessBarring extension accesses restriction).But prior art controls but without the access being proposed for neighboring server (i.e. described D2D), to avoid the overload of network and to disturb too much problem, particularly under high load capacity application scenarios and high interference scene, out-of-control permission subscriber equipment accesses Web vector graphic D2D service, can cause being further exacerbated by of network load and interference.

Detailed description of the invention

Below in conjunction with Figure of description and specific embodiment technical scheme done and further elaborate.

The embodiment of the present invention will provide for the connection control method of a kind of neighboring server and ProSeUE, the neighboring server Access Control information that will send according to base station, determine whether that described ProSeUE initiates community access request or accesses neighboring server access contention resource, thus reach to control the ProSeUE purpose accessed, can high load capacity or when high interference, reception by described Access Control information, it is to avoid initiate to access community.

Embodiment of the method:

As in figure 2 it is shown, the present embodiment provides the connection control method of a kind of neighboring server, described method includes:

Step S110: determine and forbid whether the intervalometer accessed is running；

Step S120: when described intervalometer operationally, forbid ProSeUE initiate community access request or access neighboring server access contention resource；

Step S130: when described intervalometer does not have not operationally, it is determined that whether neighboring server Access Control information includes access grade restricted information and the access grade limiting parameter for ProSe communication；

Step S140: when described neighboring server Access Control information do not include described access grade restricted information and for ProSe communication access grade limiting parameter time, it is allowed to described ProSeUE initiate community access request or access neighboring server access contention resource.

Described intervalometer can be the intervalometers such as T302 or Tbarring in user equipment (UE)；The unlatching of these intervalometers normally results in and does not allow in user equipment (UE) a period of time initiate access request or access access contention resource.

The composition of described T302 and timing startup all referring to the regulation in existing communication agreement, just can repeat no more at this opportunity.It can be determine according to the neighboring server Access Control information received from base station that the timing of described Tbarring starts.

In the present embodiment when queried described intervalometer not operationally, it is determined that whether include the access grade restricted information ac-BarringInfo access grade limiting parameter ac-BarringForProSeComm communicated with for ProSe from the neighboring server Access Control information that base station (such as evolved base station eNB) receives.

When do not include described access grade restricted information with described for the ProSe access grade limiting parameter communicated time, then represent that base station is currently not intended to limit the ProSe communication access of described ProSeUE, thus by allowing described ProSeUE initiate the access request of ProSe communication or access neighboring server access contention resource, with the community that entrance is specified.

Usual described neighboring server Access Control information is to be set up the base station transmission of wireless connections by ProSeUE geographic location and its.

The access request that in described step S130, ProSeUE initiates can be access the ProSeUE community being currently located, it is also possible to is ProSeUE other communities being currently located that the base station of community is formed at described ProSeUE position place.Described access request is neighboring server access request in step s 130.

The described access grade limiting parameter ac-BarringForProSeComm for ProSe communication also includes: for the access grade limiting parameter ac-BarringForSpecialAC of the special access grade of ProSe communication.

The described access grade limiting parameter of special access grade for ProSe communication includes the first kind for designated value for the access grade limiting parameter of the ProSe special access grade communicated.

One or more bits that described designated value is corresponding for described ac-BarringForSpecialAC are specified sequence；Specifically when as described in ac-BarringForSpecialAC correspond to 1 bit time, it is believed that this bit be 0 ac-BarringForSpecialAC be described first kind ac-BarringForSpecialAC.Specifically as described in designated value can determine according to communication protocol, it is also possible to the negotiation being based between base station and UE is determined.

Alternatively, as it is shown on figure 3, the method described in the present embodiment also includes:

Step S150: when described neighboring server Access Control information includes described access grade restricted information and during for the access grade limiting parameter of ProSe communication, it is determined that whether the AC value of described ProSeUE has at least one to be the first appointment AC value and whether described ProSeUE first specifies the access grade limiting parameter for the ProSe special access grade communicated of AC value correspondence to be the described first kind access grade limiting parameter for the ProSe special access grade communicated.

Step S160: when the access grade limiting parameter for the special access grade of ProSe communication that whether the AC value of described ProSeUE has at least to be the first appointment AC value and described ProSeUE first specifies AC value corresponding is the described first kind for the access grade limiting parameter of ProSe special access grade communicate, it is allowed to described ProSeUE initiates community access request or access neighboring server access contention resource.

It is 0,1,2 that the described AC value of ProSeUE includes AC value ... 10 AC values of 9, described AC value may also include be 11 to 15 5 AC values.Described AC value is additionally may included on the basis of the AC value of cellular communication newly-increased one or more AC values, specifically such as AC value that value is 16 or 17.One ProSeUE potentially includes the AC value that multiple value is different.Described step S160 judges whether one or more AC values of described ProSeUE have specify when one first to specify AC value in the present embodiment.Described first appointment AC value can be the one or more AC values specified in above-mentioned AC value.

Concrete as, if current first specifies the value of AC value can include being 11 to 15；If the AC value of current ProSeUE is that in 0 to 9, concrete value is the AC value of 4, it is determined that the AC value of described front ProSeUE does not include described first and specifies AC value.If ProSeUE includes multiple AC value, if these AC values include be 12 AC value, it is determined that the AC value of described ProSeUE has at least one be described first specify AC value.

The neighboring server Access Control information that user equipment (UE) sends according to base station in the present embodiment, it is determined whether initiate access request or access neighboring server access contention resource；So can facilitate base station that described ac-BarringForSpecialAC is set according to the annoyance level of himself load and the community of measurement, and then reach to control the Access Control of ProSeUE.The described access grade limiting parameter for ProSe communication includes the access grade restriction factor for ProSe communication；

As it is shown on figure 3, described method also includes:

Step S170: when the AC value of described ProSeUE does not have the access grade limiting parameter of the first of the first appointment AC value or the described ProSeUE special access grade for ProSe communication specifying AC value corresponding not to be the described first kind for the access grade limiting parameter of the ProSe special access grade communicated, generate a random number；

Step S180: described random number is compared with being used for the ProSe access grade restriction factor communicated；

Step S190: when described random number is less than described access grade restriction factor, it is allowed to described ProSeUE initiates community access request or accesses neighboring server access contention resource.

Further, as it is shown on figure 3, described method also includes:

Step S200: when described in described random number is not less than for the ProSe access grade restriction factor ac-BarringProSeFactor communicated, forbid that described ProSeUE initiates community access request or accesses neighboring server access contention resource.

Described random number is stochastic generation.The span of described random number is identical with the described span for the access grade restriction factor of ProSe communication, when the described access grade restriction factor span 0 to 1 for ProSe communication, then the described access grade restriction factor for ProSe communication is also 0 to 1；And generally the interior number of span is equally distributed random number.

But it is that determine according to communication protocol between described span base station and user equipment (UE) or based on consulting to determine.

When generating random number, the probability generating any one random number according to statistical probability subscriber equipment is all identical；If now the described numerical value for the access grade restriction factor of ProSe communication is big, then described ProSeUE is allowed to initiate access request or to access the probability of neighboring server access contention resource bigger.

When base station is busy, it is possible to limit the access of ProSeUE by arranging the less access grade restriction factor for ProSe communication of value.

If described ProSeUE includes 2 priority, as in the AC value of 0 to 9, it is believed that the priority of the AC value correspondence of 0 to 4 is higher than the AC value being 5 to 9.Described ProSeUE can receive two access grade restriction factors for ProSe communication differed in size to limit ProSeUE from base station, when determining the AC value that AC value is 0 to 4 of ProSeUE, it is used for the access grade restriction factor for ProSe communication that the access grade restriction factor of the ProSe communication AC value more than ProSeUE is 5 to 9, it is possible to the ProSeUE making restriction AC value be 5 to 9 ensures that limiting the ProSeUE that described AC value is 0 to 4 has more transmission access request or access competitive resource chance.

The described access grade limiting parameter for ProSe communication also includes the access grade binding hours parameter for ProSe communication；

Described method also includes:

When described in described random number is not less than for the ProSe access grade restriction factor communicated, according to the described ProSe access grade binding hours parameter ac-BarringProSeTime communicated, it is determined that forbid that described ProSeUE initiates access request or accesses the disable time of neighboring server access contention resource；

Herein, the timing of described disable time can adopt the Tbarring in step S110 to carry out.

In the present embodiment when a ProSeUE is prohibited initiate access request or access competitive resource, also will determine that forbidding initiating access request or access starts after competitive resource forbidding the timing of disable time that accesses, so it can be avoided that ProSeUE is after being prohibited to access, constantly repeatedly perform step S110 to step S200, cause the problem that the energy consumption of UE is big.

Additionally, described ProSeUE is to there being different priority levels；A described AC value of the described ProSeUE of different priority levels is different at least partly.

Described method also comprises determining that the priority of described ProSe；According to described priority determine for compare with described random number for the ProSe access grade restriction factor communicated.The priority of the described ProSeUE of the i-th priority is lower than the ProSeUE of the i-th-1 priority.ProSeUE described in described i-th priority corresponding for ProSe communication access grade restriction factor be i-th for ProSe communication access grade restriction factor.Described i-th is used for the access grade restriction factor of ProSe communication lower than described i-th-1 for the access grade restriction factor of ProSe communication；Described i be not less than 2 integer.

When realizing, the priority of described ProSeUE can be determined by special priority parameters, AC value can also be specified to determine by non-first, but specified AC value to determine by described first in the present embodiment, so can simplify described neighboring server Access Control information, it is thus possible to simplify base station to form the step of described neighboring server Access Control information, and the quantity of information of described neighboring server Access Control information can be reduced.

Such scheme shows: the described access grade restriction factor for ProSe communication that the AC value of the described ProSe of high priority is corresponding, more than the access grade restriction factor being used for ProSe communication described in the AC value correspondence of the described ProSe of low priority.

Concrete as, the priority of described ProSeUE includes high priority and non-high priority；Described non-high priority is lower than the priority level of described high priority.Thus can guarantee that high priority has higher probability to carry out the access of ProSe communication.

When realizing, the described access grade limiting parameter for ProSe communication includes multiple access grade restriction factor for ProSe communication；The AC value of different ProSeUE that the different access grade restriction factors for ProSe communication is corresponding；And the corresponding different priority of these AC values.

It is different that different AC values are likely to corresponding priority, it is also possible to is the different priority of different attribute value correspondence of same AC value.The AC value of described ProSeUE and the priority of ProSeUE have certain mapping relations in a word.Can be commonly used for the AC value of the priority of expression ProSeUE is the described first AC value specifying in AC value；Specifically when as described in an AC value include be 11 to 15 AC value, what also include increasing newly is the AC value of 16 or 17 simultaneously, and its ProSeUE priority being likely to some AC value is higher than the ProSeUE of another AC value.Further, the priority including the ProSeUE of the first appointment AC value is likely to the priority of the ProSeUE than the AC value that AC value is 0 to 9.What which AC value concrete was corresponding is high priority, it is possible to determine according to the negotiation between base station and UE, it is also possible to be determine according to communication protocol.

ProSeUE in order to enable priority high has higher access probability in the present embodiment, the value for the access grade restriction factor of ProSe communication corresponding to the higher ProSeUE of priority level is higher, thus the random number generated is bigger less than the described probability for the access grade restriction factor of ProSe communication.

Concrete as, when the AC value in described AC value being 11 to 15 is the described first kind for the access grade limiting parameter ac-BarringForSpecialAC of the ProSe special access grade communicated, if the AC value of current ProSeUE includes the AC value of 13, then confirm that the access grade limiting parameter for the special access grade of ProSe communication corresponding to the AC value of described ProSeUE includes the described first kind access grade limiting parameter for special access grade that ProSe communicate, at this moment will allow it to initiate access request and access competitive resource.

In ProSeUE described in the present embodiment, the AC value of storage or the AC value of described neighboring server Access Control information can be all the AC value in cellular communication is identical, and now, described AC value can be not only used for cellular communication, is additionally operable in the ProSe communication described in the present embodiment.Due to the application of AC value applied in cellular communications very extensive, therefore ProSe communication can the AC value of direct multiplexing cellular communication, without again arranging specially again, with cellular communication, there is very strong compatibility, simplification access operation thus having.Now, described first AC value is specified obviously to may also be the one or more AC values for using in cellular communication.

Additionally, the AC value of described ProSeUE is the AC value being exclusively used in described ProSe communication.Described AC value is specifically designed to ProSe communication, it is clear that be independent with the AC value in cellular communication, but above-mentioned flow process can also be adopted to carry out ProSe communication；The advantage of this setup is, being conducive to communicates with ProSe to cellular communication respectively is controlled.

In concrete implementation process, the AC value of described ProSeUE self storage, it is possible to be stored in the described ProSeUE SIM carried or usim card.Described SIM is the abbreviation of SubscriberIdentityModule client identification module, also referred to as subscriber identification card, smart card；One of necessaries usually communicated based on radio communication mark in radio communication.Described USIM is the abbreviation of UniversalSubscriberIdentityModule.Described usim card refers to third generation Mobile phone card, also known as (user whole world identification card, or universal subscriber identity module (USIM), time also referred to as upgrading after SIM.

Described method also includes:

Inquire about the configuration information of described ProSeUE；

Described neighboring server Access Control information can include limiting (AccessClassBarring based on access grade, ACB) the neighboring server Access Control information of mechanism, the next-door neighbour that can also include accessing restriction (ExtendedAccessBarring, EAB) mechanism based on extension services Access Control information.

The neighboring server Access Control information used in described step S110 to step S200 may be based on the neighboring server Access Control information of ACB mechanism, and the configuration information in ProSeUE is combined use, with the restricted part UE neighboring server Access Control information accessed, then may be based on the neighboring server Access Control information of described EAB mechanism.

When carrying out described ProSe and accessing, generally include discovery procedure and communication process, being chosen as the described neighboring server Access Control information based on ACB mechanism in the present embodiment in the ProSe communication process accessed, the described neighboring server Access Control information based on described EAB mechanism is then preferably and is applied in the ProSe discovery procedure accessed.

The information that some subscriber equipment sends by receiving described base station forms described configuration information, it is also possible to is form described configuration information when carrying out equipment generation, or is stored described configuration information by SIM or usim card；And described SIM or USIM generally determines communication identifier, therefore the configuration information that described configuration information can be formed for the difference according to communication identifier.

Described method also includes:

Specifically such as system message as described in receiving on from broadcast channel, described system message includes described Access Control information.Described Access Control information can also be obtained from being specifically designed to the specific information transmitting described Access Control information.Both approaches is respectively provided with and realizes easy advantage.In implementing process, described system message or dedicated signaling may periodically be broadcasted in described base station, the described ProSeUE then now performing said method periodically can receive described neighboring server Access Control information from described broadcast channel, and for controlling the access of described ProSeUE neighboring server in this cycle.

Below in conjunction with above-mentioned any technical scheme, it is provided that several concrete examples:

Example one:

What this example described is that competitive resource is initiated in D2D communication and/or application accesses and uses honeycomb ACB mechanism AC value to access the flow process of community when network prepares for ProSeUE.The mode accessing community by initiating competitive resource is the first resource method of salary distribution in D2D communication；The mode accessing network based on application is the Secondary resource method of salary distribution in D2D communication.In the Secondary resource method of salary distribution, in order to apply for that resource carries out the data transmission etc. of D2D communication to eNB, ProSeUE needs to access network and enters connected state.

ProSeUE is when needs carry out D2D communication, and under network comparatively congestion situation, competition need to be initiated by network and/or application access is ready for controlling.ProSeUE use the AC value in its ACB mechanism being set in cellular networks be at war with initiate and/or access situation control；Other ACB parameter relevant to for D2D communication access is transmitted by the eNB system information by ProSe or dedicated signaling simultaneously, and parameter information includes " ac-BarringInfo ", " ac-BarringForProSeComm ", " ac-BarringProSeFactor ", " ac-BarringProSeForSpecialAC " and " ac-BarringProSeTime " etc.；After obtaining these informations parameter, ProSeUE, when carrying out initiating competitive resource and/or applying for that accessing network prepares for D2D communication, uses ACB parameter relevant for ProSe be calculated and judge, to determine whether to access what whether described ProSeUE community was accessed.

As it is shown in figure 5, ProSeUE described in this example uses honeycomb ACB mechanism AC value to include when carrying out initiating competitive resource and/or application access network preparation for D2D communication:

Step S101: judge whether T302 or Tbarring etc. is running.Described T302 and described T303 etc. is forbidding described in above-described embodiment and accesses timer.When described T302 or Tbarring etc. operationally, enter step S108；When described T302 or Tbarring etc. does not run, enter step S102.It is effective that described Tbarring or T302 etc. forbid accessing timer in operation expression, forbids that the time accessed also does not terminate.Described Tbarring or T302 etc. do not run expression and forbid that access timer is invalid, forbid that the time accessed is over or does not have startup to forbid accessing timing.

Step S102: judge whether include ac-BarringInfo and ac-BarringForProSeComm the Access Control information received from base station；If so, step S103 is then entered；If it is not, then enter step S104.

Step S103: judge whether ProSeUE has one or more AC value to be 11 to 15, and the ac-BarringForSpecialAC corresponding bit corresponding to AC value of the 11 to 15 of described ProSeUE whether arrange be 0, if so, then enter step S104, if it is not, then enter step S105.

Step S104: permit accessing the competitive resource Chi Huo community being assigned with.

Step S105: take a random number between [0,1].

Step S106: judge that whether random number is lower than the value accessing restriction factor ac-BarringFactor in ac-BarringForProSeComm；If so, step S104 is then entered, if it is not, then enter step S107.

Step S107: forbid accessing the competitive resource Chi Huo community being assigned with.

Based on the further improvement of this example, in public safety field and/or other special circumstances, ProSeUE can be divided into ProSeUE and the non-high priority ProSeUE two class rank of high priority.The ProSeUE of high priority has higher access rank than the ProSeUE of non-high priority；It is set to the ProSeUE of high priority, it is necessary in case of emergency can preferentially enjoy acquisition resource and send the authority such as data, by one of this kind of ProSeUE its access grade AC value being set to special high priority, if AC value is 12 etc..Send again through Access Control information and there is the AC value of high priority, such ProSeUE by with the mating of the AC value of self, make the ProSeUE of high priority have bigger probability access competitive resource Chi Huo community.

Example two:

As shown in Figure 6, ProSeUE described in this example uses honeycomb ACB mechanism AC value to include when carrying out initiating competitive resource and/or application access network preparation for D2D communication:

Step S101: judge whether T302 or Tbarring etc. is running.Described T302 and described Tbarring etc. is forbidding described in above-described embodiment and accesses timer.When described T302 or Tbarring etc. operationally, enter step S108；When described T302 or Tbarring etc. does not run, enter step S102.It is effective that described Tbarring or T302 etc. forbid accessing timer in operation expression, forbids that the time accessed also does not terminate.Described Tbarring or T302 etc. do not run expression and forbid that access timer is invalid, forbid that the time accessed is over or does not have startup to forbid accessing timing.

Step S103 ': judge whether ProSeUE has one or more AC value to be the first appointment AC value, and the described ProSeUE first ac-BarringForSpecialAC corresponding bit of specifying AC value corresponding whether arrange be 0, if so, then enter step S104, if it is not, then enter step S105A.Herein, one or more AC values of setting up on the described first basis specifying the AC value that AC value includes providing in cellular communication, specifically such as AC value etc. that value is 16 or 17.

Step S105A: determine whether described ProSeUE includes the AC value of high priority；If entering step S105B；Enter step S105C if not；

Step S105B: determine that the first of high priority AC value correspondence accesses the value of restriction factor ac-BarringFactor1；

Step S105C: determine that the first of high priority AC value correspondence accesses the value of restriction factor ac-BarringFactor2

Step S105: take a random number between [0,1].

Step S106: judge that whether random number is lower than the value accessing restriction factor ac-BarringFactor in ac-BarringForProSeComm；If so, step S104 is then entered, if it is not, then enter step S107.Ac-BarringFactor herein, when described ProseUE includes high priority AC value, described ac-BarringFactor is described ac-BarringFactor1；When described ProseUE does not include high priority AC value, described ac-BarringFactor is described ac-BarringFactor2.

Example three: ProSeUE is when needs carry out D2D discovery, and ProSeUE requires over competitive way and obtains resource.In the Secondary resource method of salary distribution, in order to apply for that resource carries out the data transmission etc. of D2D discovery to eNB, ProSeUE needs to access network and enters connected state.Under network comparatively congestion situation, competition need to be initiated by network and/or application access is ready for controlling.ProSeUE carry out D2D find time, it is provided with configuration information based on EAB mechanism, then the ProSeUE being configured for EAB carry out initial urgent call, ProSe communication the ProSeUE that AC value is 11 to 15 will ignore any EAB information of any Web broadcast.If network does not broadcast EAB information, ProSeUE will perform ACbarring, and conduct interviews control to the competitive resource pond/community being assigned with.If the EAB information of Web broadcast does not forbid this ProSeUE, then ProSeUE will perform ACbarring；Otherwise the competitive resource pond/community being assigned with is denied access by this ProSeUE.If multiple core net share same Access Network, Access Network to use EAB respectively for different core net.
