Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, by the following examples and referring to the drawings, the present invention is described in more detail.
Embodiment one
Virtual network operator connects into rank to MTC device or MTC component, and this access rank can be preset in MTC device or MTC group, or is arranged in the ID card of MTC device, it is also possible to is saved in HSS as subscription data.
In the present invention, accessing rank can be allocated according to the demand of user, will be respectively configured access rank to its MTC device or MTC group according to user's request；Or, it is also possible to access rank according to the distribution of MTC service type, i.e. access rank according to APN (APN, AccessPointName) distribution；In addition, Virtual network operator can also arrange the access rank of MTC device or MTC group according to the management strategy of self.
Access rank and can be defined as different priority according to its order, such as, when using 0 to 9 such numeral to arrange access rank, the numeral that can be defined as accessing rank corresponding is the least, and rank is the highest；When using the such letter of A to Z to arrange access rank, the lexicographic order that can be defined as accessing rank corresponding is the most forward, and rank is the highest.In addition, it is also possible to by the priority orders of each grade of network settings.As long as accessing rank can embody different MTC device or the access priority of MTC group.
Accessing rank can be static state setting, no longer changes after i.e. arranging, and such as, above-mentioned is directly configured at accessing rank in the identity card in MTC device or in MTC device.Can also be dynamically to arrange in the present invention, after i.e. arranging corresponding access rank, the access rank of different MTC device or MTC group can be adjusted by network according to factors such as current network loads, and notifies MTC device by the way of broadcast or signaling.
Further, network side is that different access ranks configures corresponding access parameter, and concrete, access parameter includes access probability and accesses the waiting time.The corresponding access probability of each access rank and an access waiting time.Wherein the value of access probability is between 0 to 1.Here, the present invention is only by way of the means similar with " probability " and is controlled the access of MTC device, and it is true that above-mentioned numerical range can be any number scope, such as 1 to 100,1 to 1000 etc..
The access parameter of configuration is sent to MTC device or MTC group by the way of broadcast or signaling by network.If network change access parameter, then the access parameter after change is sent to MTC device or MTC group again by the mode of broadcast or signaling.
MTC device receives system message or the signaling of broadcast, therefrom reads access parameter.Access parameter if receiving access parameter before MTC device, then before using the access parameter of up-to-date reading to cover.
In the present invention, the mode that above-mentioned access parameter can also be identical with accessing rank, it is arranged in the identity card in MTC device or in MTC device.
Fig. 2 is the flow chart that the present invention controls the embodiment of the method one of machine type communication device access network, as in figure 2 it is shown, the method that this example controls machine type communication device access network comprises the following steps:
Step 201, when MTC device or MTC group need to be linked into network, first randomly generates a random number, and the span of this random number is consistent with the numerical range of access probability, such as aforementioned access probability 0 to 1；Use this random number and access parameter self accesses access probability corresponding to rank compare, if this random number less than or no more than access probability, then perform step 201.If this random number is more than access probability, the most not initiating to access, MTC device starts an intervalometer T, is set to the value of T access the waiting time, at intervalometer to constantly, again attempts to access.Wherein attempting access to refer to again produce a random number, compare with access probability, process is identical with access procedure last time thereafter.If not comprising the waiting time in access parameter, then MTC device no longer initiates access request.
The mode that above-mentioned random number compares with access probability, it is that access rank is the highest, by the mechanism that the value of its access probability configured is the biggest, as when accessing rank and being 10 grades, the access probability that priority is the highest is set to 1, is secondly respectively 0.9,0.8......0.1 etc..
Certainly, access probability can also be configured to, the value accessing the highest the configured access probability of rank is the least, thus, when generating the access probability that random number is more than or not less than this MTC device, allow to send access request, regenerate random number after otherwise resuming waiting for the corresponding waiting time and again attempt to access.It realizes principle as before, simply realizes details different.
Step 202, initiates access request to network side.The access request sent can be attachment request, connection request, service request, RRC connection request, TA is more newly requested, RA is more newly requested and in PDN connection request any one.
In this example, the mode preferably using access parameter to be dynamically configuration, thus, network can change access parameter dynamically according to loading condition.When heavier loads, network can reduce some or the access probability of multiple access rank, or increases its access waiting time；When light load, network can increase some or the access probability of multiple access rank, or reduces its access waiting time.When network needs to forbid that the MTC device of certain rank or MTC group device access, its access probability can be set to 0.
Embodiment two
Network joins access priority to MTC device or MTC component；Priority could be arranged to height, low two ranks, or is set to height, in, low three ranks, or other any ranks needed according to network.The MTC device of distribution or the access priority of MTC group can be saved in network entity HSS as subscription data, or are saved in network entity MME.
After preserving access priority information in network entity, network can be according to the priority of its correspondence of identifier lookup of MTC device or MTC group.MTC device or MTC group are initiated to typically require, during access request, the mark comprising oneself in demand signalling, after network entity receives this mark, then can know which priority this MTC device or MTC group are according to mark.
If priority is set to high and low two ranks, network side pre-sets two load-threshold value S_High and S_Low, the most corresponding high, low two ranks, if current network load exceedes threshold value S_Low, then refuse to be configured to the access request of the MTC device of low access priority；If current network load exceedes threshold value S_High, then refusal is configured to the access request that the MTC of high access priority and low access priority is arranged.
If priority is set to height, neutralizes low three ranks, network pre-sets three load-threshold value S_High, S_Medium, S_Low, the most corresponding high, medium and low three ranks, if current network load exceedes threshold value S_Low, then refuse to be configured to the access request of the MTC device of low access priority；If current network load exceedes threshold value S_Medium, then refusal is configured to the access request that the MTC of middle access priority and low access priority is arranged, if current network load exceedes threshold value S_High, then refusal is configured to high access priority, the access request that the MTC of middle access priority and low access priority is arranged.
When priority is set to more rank, analogize according to aforesaid way, describe in detail the most one by one.
Or, it is also possible to the corresponding relation between priority and network side load threshold value is set in the following manner.
If priority is set to high and low two ranks, network pre-sets two load-threshold value S_High and S_Low, the most corresponding high, low two ranks, if current network load exceedes threshold value S_Low, then refuse to be configured to the access request of the MTC device of low access priority；If current network load exceedes threshold value S_High, then refusal is configured to the access request that the MTC of high access priority and low access priority is arranged.
If priority is set to height, neutralizes low three ranks, network pre-sets three load-threshold value S_High, S_Medium, S_Low, the most corresponding high, medium and low three ranks, if current network load exceedes threshold value S_Low, then refuse to be configured to the access request of the MTC device of low access priority；If current network load exceedes threshold value S_Medium, then refusal is configured to the access request that the MTC of middle access priority and low access priority is arranged, if current network load exceedes threshold value S_High, then refusal is configured to high access priority, the access request that the MTC of middle access priority and low access priority is arranged.
When priority is set to more rank, analogize according to aforesaid way, describe in detail the most one by one.
Fig. 3 is the flow chart that the present invention controls the embodiment of the method two of machine type communication device access network, as it is shown on figure 3, the method that this example controls machine type communication device access network comprises the following steps:
Step 301, MTC device initiates access request to network side；The access request sent can be attachment request, connection request, service request, RRC connection request, TA is more newly requested, RA is more newly requested and in PDN connection request any one.Above-mentioned access request comprises this MTC device or the access priority information of MTC group belonging to it, or above-mentioned access request comprises this MTC device or the identification information of MTC group belonging to it.Identification information includes the information of the identification module of MTC device, or the identification information such as the label comprising MTC group.
Step 302, after network side receives the access request of MTC device, obtains MTC device or the access priority of MTC group belonging to it, determines whether this access request access network according to current load.
Concrete, when access request comprises the access priority information of this MTC device or MTC group belonging to it, directly obtain.And when comprising the identification information of this MTC device or MTC group belonging to it in access request, network can find out this MTC device or the access priority of MTC group belonging to it according to identification information in subscription data.
After step 302, if network side have rejected the access request of MTC device, then can carry access request in refusal demand signalling and send the waiting time, MTC device, after receiving refusal request, initiates access request the most again.
Embodiment three:
Virtual network operator joins access priority to MTC device or MTC component, and this access priority can be preset in MTC device or MTC group, or is arranged in the ID card of MTC device, it is also possible to is saved in HSS as subscription data.
In the present invention, access priority can be allocated according to the demand of user, will be respectively configured access priority to its MTC device or MTC group according to user's request；Or, it is also possible to distribute access priority according to MTC service type, i.e. distribute access priority according to APN；In addition, Virtual network operator can also arrange MTC device or the access priority of MTC group according to the management strategy of self.
Access priority can be defined as different priority according to its order, such as, when using 0 to 9 such numeral to arrange access priority, the numeral that can be defined as access priority corresponding is the least, and priority is the highest；When using the such letter of A to Z to arrange access priority, the lexicographic order that can be defined as access priority corresponding is the most forward, and priority is the highest.
Access priority can be static state setting, no longer changes after i.e. arranging, and such as, above-mentioned is directly configured at access priority in the identity card in MTC device or in MTC device.Can also be dynamically to arrange in the present invention, after i.e. arranging corresponding access priority, the access priority of different MTC device or MTC group can be adjusted by network according to factors such as current network loads, and notifies MTC device by the way of broadcast or signaling.
Further, network side is that different access priorities configures corresponding access parameter, concrete, and access parameter includes whether the access instruction allowing to access and accesses the waiting time.Corresponding one of each access priority accesses instruction and an access waiting time, or the most corresponding one of each access priority accesses instruction.
The access parameter of configuration is sent to MTC device or MTC group by the way of broadcast or signaling by network.If network change access parameter, then the access parameter after change is sent to MTC device or MTC group again by the mode of broadcast or signaling.
MTC device receives system message or the signaling of broadcast, therefrom reads access parameter.Access parameter if receiving access parameter before MTC device, then before using the access parameter of up-to-date reading to cover.
In the present invention, the mode that above-mentioned access parameter can also be identical with access priority, it is arranged in the identity card in MTC device or in MTC device.
Fig. 4 is the flow chart that the present invention controls the embodiment of the method three of machine type communication device access network, and as shown in Figure 4, this example controls the method for machine type communication device access network and comprises the following steps:
Step 401, when MTC device or MTC group need to be linked into network, according to the access parameter read, if the access instruction of correspondence is not allow to access, the most not initiating to access, if comprising the waiting time, then again initiating to access after the waiting time, if not comprising the waiting time, the most no longer initiate to access.
Step 402, initiates access request to network side.The access request sent can be attachment request, connection request, service request, RRC connection request, TA is more newly requested, RA is more newly requested and in PDN connection request any one.
In this example, the mode preferably using access parameter to be dynamically configuration, thus, network can change access parameter dynamically according to loading condition.When heavier loads, some can be allowed the priority accessed to be adjusted to and not allow access by network；When light load, some can not allowed the priority accessed to be adjusted to permission access by network.
