In the practical application of the embodiment of the present invention, dual link user ID value scope consults jointly to determine after can also carrying out repeatedly information interaction by macro cell base station and small-cell base station.Preferably, after reserved dual link user ID value scope is indicated to all small-cell base stations, and before having dual link user access, macro cell base station can obtain all small-cell base stations, and to feed back which C-RNTI value within the scope of this available, and by macro cell base station collect all small-cell base stations feed back with macro cell base station can C-RNTI value occur simultaneously after, then by occur simultaneously be indicated to all small-cell base stations.
Correspondingly, all small-cell base stations feed back within the scope of reserved dual link user ID value to macro cell base station, the dual link user ID value scope that self is available; Then all small-cell base stations receives and is specified by macro cell base station, all small-cell base stations and macro cell base station all can the common factor of dual link user ID value scope, as reserved dual link user ID value scope.Now, small-cell base station obtains needs reserved C-RNTI scope, then again the C-RNTI value within the scope of this can not be distributed to domestic consumer.This way avoids the problem that reserved C-RNTI is taken by domestic consumer, and utilance is higher, can not cause the wasting of resources.In addition, small-cell base station, without the need to facing because C-RNTI distributes to domestic consumer, causes the problem that need discharge access, also would not affect the experience of domestic consumer.
In the practical application of the embodiment of the present invention, the priority of dual link user can higher than domestic consumer.Preferably, after dual link ident value and macro cell base station share by dual link small-cell base station, can also comprise:
When described dual link ident value is not distributed to other users by dual link small-cell base station, access described dual link user;
When described dual link ident value is distributed to existing user by dual link small-cell base station, judge the priority of existing user and described dual link user: priority that is identical with the priority of dual link user as existing user or dual link user is lower, and dual link small-cell base station feeds back access failure to macro cell base station; When the priority of dual link user is higher, now existing user discharges by dual link small-cell base station, access dual link user, and this dual link ident value and dual link user profile one_to_one corresponding is stored.
In one embodiment of the invention, when the quantity adjustment of dual link user in a period of time is very large, C-RNTI scope reserved before may causing is not enough to the access demand meeting dual link user, and now MeNB can adjust dual link user ID value scope as required.Further, all SeNB receptions are indicated by MeNB, according to the reserved dual link user ID value scope that the quantity of dual link user adjusts.SeNB also can feed back available C-RNTI scope again, makes MeNB specify the common factor of available C-RNTI scope in final all SeNB and MeNB as the C-RNTI scope after adjustment.This way is convenient, flexible, can the demand of dynamically adapting dual link user, substantially increases the utilance of C-RNTI resource.
In the practical application of the embodiment of the present invention, due in dual link scene, the return link between MeNB and SeNB is undesirable, so carry out information interaction between two base stations can introduce a new Xn interface, also can use original X2 interface.Time between MeNB and SeNB by Xn or X2 interface mutual dual link user's context, dual link user ID value scope can be coordinated, transmission dual link user connection status.Wherein, preferably, newly can define one and distribute to dual link user C-RNTI used by the signaling message transmission of Xn interface or X2 interface transmission; If X2 interface can be used, also can increase information element (IE) instruction and distribute to dual link user C-RNTI used in existing X2 message.
Distribute dual link user ID value to be specially accessed dual link user below, the specific implementation process of the embodiment of the present invention be described respectively for two example two:
Embodiment 1:
The embodiment of the present invention 1 for small-cell base station after receiving reserved dual link user ID value scope, without the need to the situation to macro cell base station feedback usable range, see Fig. 3:
Step 301: reserved dual link user ID value scope is indicated to all small-cell base stations by macro cell base station.
In this step, by macro cell base station determination dual link user ID value scope, in embodiments of the present invention, be 003D-FFF3, this scope is assigned to all small-cell base stations by macro cell base station.In the embodiment of the present invention, the signaling message transmission every terms of information transmitted by Xn interface by of new definition between macro cell base station and small-cell base station.After this C-RNTI value that can not reallocate within the scope of this of all small-cell base stations is to domestic consumer.
Step 302: macro cell base station receives the access request that dual link user sends.
In this step, macro cell base station receives the access request that user sends, and judge whether this user can carry out dual link according to the relevant parameter of user, when possible, macro cell base station and dual link user carry out wireless heterogeneous networks (RRC) and are connected, making user enter dual link state, and determine the small-cell base station carrying out dual link, is dual link small-cell base station.
Step 303: macro cell base station from reserved dual link user ID value scope, for dual link user distributes macro cell base station the dual link ident value shared with dual link small-cell base station.
Macro cell base station is carried out in RRC connection procedure dual link user, is the C-RNTI value that dual link user is distributed within the scope of 003D-FFF3, is set to FFF1 by random access procedure.
Step 304: dual link ident value FFF1 is sent to dual link user and dual link small-cell base station by macro cell base station, instruction dual link small-cell base station and macro cell base station share the dual link ident value of distribution.
Step 305: dual link small-cell base station judges the access state of dual link ident value.
When dual link ident value FFF1 is not assigned to other users, enter step 306; When dual link ident value FFF1 has been assigned to existing user, enter step 307.
Step 306: dual link small-cell base station access dual link user.
When this dual link ident value is not assigned with, dual link small-cell base station directly accesses dual link user, and is labeled as by this C-RNTI value FFF1 and takies, by itself and dual link user profile one_to_one corresponding.
Step 307: dual link small-cell base station judges dual link user, and whether priority is higher.
When the two priority is identical, or when dual link User Priority is lower, enter step 308; When dual link User Priority is higher, enter step 309.
Step 308: dual link small-cell base station feeds back access failure to macro cell base station.
Step 309: existing user discharges by dual link small-cell base station, access dual link user.
Existing user discharges by dual link small-cell base station, and user connects with dual link, and is labeled as by this C-RNTI value FFF1 and takies, by itself and dual link user profile one_to_one corresponding.
So far, then completing in the embodiment of the present invention 1 is the process of a dual link user allocation identification.

Macro cell base station finally determines the scope of C-RNTI value, is 004D-FFF3, is then indicated to all small-cell base stations.After this C-RNTI value that can not reallocate within the scope of this of all small-cell base stations is to domestic consumer.
Step 405: macro cell base station receives the access request that dual link user sends.
In this step, macro cell base station receives the access request that user sends, and judge whether this user can carry out dual link according to the relevant parameter of user, when possible, macro cell base station and dual link user carry out wireless heterogeneous networks (RRC) and are connected, making user enter dual link state, and determine the small-cell base station carrying out dual link, is dual link small-cell base station.
Step 406: macro cell base station from reserved dual link user ID value scope, for dual link user distributes macro cell base station the dual link ident value shared with dual link small-cell base station.
Macro cell base station is being carried out in RRC connection procedure, is the C-RNTI value that dual link user is distributed within the scope of 004D-FFF3, is set to FFF1 by random access procedure.
Step 407: dual link ident value FFF1 is sent to dual link user and dual link small-cell base station by macro cell base station, instruction dual link small-cell base station and macro cell base station share the dual link ident value of distribution.
Step 408: dual link small-cell base station access dual link user, and this C-RNTI value FFF1 is labeled as takies, by itself and dual link user profile one_to_one corresponding.
Now, because dual link user ID value scope is determined by MeNB and SeNB joint consultation, so can not there is the problem that reserved C-RNTI value taken by domestic consumer, dual link small-cell base station can direct access dual link user, and by FFF1 and dual link user profile one_to_one corresponding.
