Description of drawings
Fig. 1 is the flow chart of the embodiment of the invention.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples, and with reference to accompanying drawing, the present invention is described in more detail.
Core concept of the present invention is: each user is set priority, and increase sign and the variable that is provided for finishing the gravity treatment of differentiation sub-district; User terminal is according to the User Priority of setting, and the network sign that is used for the gravity treatment of differentiation sub-district and the variable that issue, adjusts cell reselection parameters and finishes the gravity treatment of differentiation sub-district.Here, the sub-district gravity treatment of so-called differentiation is meant according to user's diversity ratio adjusts cell reselection parameters as the priority at different user, finishes the sub-district gravity treatment.
For finishing method proposed by the invention, need three signs and a variable be set to finish the gravity treatment of differentiation sub-district in the network side increase at least.Described three are masked as: 1) differentiation sign (DifferFlag), and whether be used to refer to user terminal needs to start the gravity treatment of differentiation sub-district; 2) the responsive sign of priority (ClassFlag), network side is by being provided with this sign for cell reselection parameters, and indicating this cell reselection parameters to user terminal is the priority sensitive parameter; 3) strong and weak Warning Mark (StrongWeakFlag), network side is by being provided with this sign for the priority sensitive parameter, being used for to user terminal indication is mode to reduce, or the raising mode is adjusted the priority sensitive parameter, the StrongWeakFlag sign is put 0 expression improve, the StrongWeakFlag sign is put 1 expression and is reduced.A described variable is step-length gain (StepGain) variable, the gain that expression is brought when using User Priority to adjust the priority sensitive parameter.
Wherein, so-called priority sensitive parameter is meant: in realizing the differentiation cell reselection process, be confirmed as the cell reselection parameters of adjusting based on User Priority.The priority sensitive parameter can be determined when initiating the gravity treatment of differentiation sub-district by network side, also can be consulted to determine that quantity is one or more by network side and user terminal in advance.The regulation rule of priority sensitive parameter consult to be determined with user terminal in advance by network side, for network side and user terminal in common knowledge.For example, only select a priority sensitive parameter X, then the rule of Tiao Zhenging can be X ± SubClassStepGain, wherein, still is that minus sign is by the decision of the pairing StrongWeakFlag sign of X with plus sige.For compatible original system and avoid bigger modification to original system, can utilize free time in original message flow and reserved field to transmit increases sign and the variable that is provided with as far as possible.
Described differentiation sign has two kinds of set-up modes in actual applications: first kind is, network side is provided with the DifferFlag sign when needs start the gravity treatment of differentiation sub-district, and set DifferFlag sign is handed down to user terminal, user terminal has detected this DifferFlag sign and has just started the gravity treatment of differentiation sub-district.Second kind is, no matter whether start the gravity treatment of differentiation sub-district, network side all is provided with a DifferFlag sign, and DifferFlag sign is handed down to user terminal with StrongWeakFlag sign, ClassFlag sign and StepGain, just need start the situation of differentiation sub-district gravity treatment at network side, the DifferFlag sign is set to effectively, and at the situation that does not need to start the gravity treatment of differentiation sub-district, it is invalid that the DifferFlag sign is set to; User terminal is received and is changed to effective DifferFlag sign, then carries out differentiation sub-district gravity treatment according to StrongWeakFlag sign, ClassFlag sign and StepGain; User terminal is received and is changed to invalid DifferFlag sign, then ignores StrongWeakFlag sign, ClassFlag sign and StepGain, finishes cell reselection process according to existing normal flow.Only be masked as example below to adopt the second way that DifferFlag is set.
The implementation process of present embodiment is: at first by Virtual network operator before user terminal adds network, set User Priority according to concrete user.In the network operation stage, start differentiation sub-district gravity treatment by network side, and issue newly-installed DifferFlag sign, StrongWeakFlag sign, ClassFlag sign and StepGain variable to user terminal by broadcast channel.User terminal passes through to receive these signs and variable, difference in response alienation sub-district gravity treatment, and sign that utilization issues according to User Priority and variable are adjusted cell reselection parameters, finish the sub-district gravity treatment of differentiation.Concrete steps are as shown in Figure 1:
Step 11: user terminal was set User Priority by Virtual network operator according to user's classification, importance or particularity before adding network.
The establishing method of User Priority can obtain user-priority field (SubClass) by user's international mobile subscriber identity (IMSI) mapping, and is stored in the subscriber terminal equipment.Mapping ruler can be selected arbitrarily by network side.For example: the Mobile Country Code MCC in the international mobile subscriber identity (MCC) field can be shone upon and obtain User Priority, be mapped as SubClass=0 with 000～399,400～699 are mapped as SubClass=1, and 700～999 are mapped as SubClass=2; Perhaps odd number wherein is mapped as SubClass=0, even number is mapped as SubClass=1.
Also the different field that inserts class (AC) can be mapped as different user-priority field, and be stored in the subscriber terminal equipment, mapping mode is any.Wherein inserting class is to be stored in the SIM card of mobile phone users, is used for controlling the parameter of accessing network by mobile user.Each domestic consumer all has one to insert class.Insert class and be divided into grade 0 to 90 kinds of grades.For example, the state of emergency or certain network generation catastrophe failure or the like occur in certain areas, can utilize the access class control user access network in the SIM card.
Perhaps can also directly in subscriber identification module (SIM) or common user identification module (USIM) card, increase new SubClass field, be used for setting user's priority level.For example: SubClass=1 represents that User Priority is 1, and SubClass=2 represents that User Priority is 2.
User Priority can divide into two or more, but for fear of the complexity of system, the priority with the user is divided into 2 ranks usually.
Step 12: network side, is changed to the DifferFlag sign effectively when needs start the gravity treatment of differentiation sub-district according to load measurement results and actual operating state.For example overcrowding or when emergency occurring, it is resident to allow the high user of priority to continue at network, and the low user of priority transfers in other sub-districts and goes.
Network side is when starting the differentiation cell reselection process, at first determine the User Priority sensitive parameter, for determined priority sensitive parameter the StrongWeakFlag sign is set respectively then, at last, for each priority sensitive parameter setting StepGain separately, perhaps all priority sensitive parameters are set a StepGain.
Wherein, if the priority sensitive parameter is to be consulted in advance to determine by network side and user terminal, the cell reselection parameters that then will consult in advance to determine is as the priority sensitive parameter, and at this moment, network side is provided with the ClassFlag sign for the priority sensitive parameter of consulting in advance to determine; If in starting the differentiation cell reselection process, select the priority sensitive parameter, the services selection priority sensitive parameter that provides according to network environment and the required network of user then, and indicate for the priority sensitive parameter is provided with ClassFlag.For example, if it is overcrowding owing to network in this sub-district, the network side decision only need continue as the high user's service of priority, then the priority sensitive parameter of selecting this moment can be to help the resident cell reselection parameters of user, be made as X,, and the StrongWeakFlag sign put 0 for this priority sensitive parameter is provided with the ClassFlag sign, expression is adjusted the priority sensitive parameter in the mode that improves, and the occurrence of StepGain can rule of thumb be worth or the environment of network is determined.
Determined priority sensitive parameter, sign and the variable of user's differentiation sub-district gravity treatment when network side after, be handed down to user terminal in the sub-district with original cell reselection parameters by broadcast.
Step 13: user terminal is after receiving the broadcast that network side issues, detect the DifferFlag sign effectively, then difference in response alienation cell re-selection mechanism is carried out the adjustment of cell reselection parameters according to sign that is used for the gravity treatment of differentiation sub-district that receives and variable.
For example, because network is overcrowding, the network side decision only continues as the high user's service of priority in this sub-district.Suppose, the SubClass=1 of certain user terminal, receive that the differentiation cell reselection parameters that network side sends is StepGain=2, StrongWeakFlag=0 and definite priority sensitive parameter, only establish a priority sensitive parameter X in the present embodiment, user terminal then can adopt in advance the rule of consulting with network side, adjusts determined priority sensitive parameter.Because StrongWeakFlag=0, therefore the rule of adjusting can; X+SubClassStepGain.Obtain thus, when the priority of user terminal is high more, with respect to the low user terminal of priority, the gain that is obtained is just big more, and it is resident more to help the sub-district.
Step 14: user terminal replaces the pairing former cell reselection parameters of this priority sensitive parameter with adjusted priority sensitive parameter, and other information that are used for the sub-district gravity treatment that coupling system issues are carried out the gravity treatment of differentiation sub-district.
So far, a kind of residence reselecting based on User Priority finishes.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
