Description
Technical field
The present invention relates to communication network, relate in particular to and be used for method for communicating and device in a kind of femto cell base station.
Background technology
Wireless coverage area in the communication network generally includes one group of sub-district, and the base station in each sub-district provides various communication services to the user who is positioned at this cell coverage area.According to the size of coverage, various sub-districts can be divided into macrocell (macrocell), Microcell (microcell), picocell (picocell) etc.Recently proposed Femto cell (femtocell) again, and relevant base station is known as femto cell base station, also is known as Femto base station or Femto base station router.
Fig. 1 shows the sketch map of the exemplary communication network that comprises femto cell base station.Femto base station router (Base Station Router is called for short BSR) 1 provides the radio communication in the Femto cell 2.In other words, Femto cell 2 is meant the wireless coverage of Femto base station router 1.Femto base station router 1 links to each other with mobile network 3.For example, mobile network 3 comprises Universal Mobile Telecommunications System (UMTS) core net.Be positioned at the user terminal UE of Femto cell 2
F1, UE
F2... or UE
FnCan connect Femto base station router 1, and then be connected among the mobile network 3.Comprise also among the mobile network 3 that the user terminal that is not connected to Femto base station router 1 is such as UE
M1, UE
M2... or UE
MnInsert the user terminal of Femto base station router 1 and can realize various communication services through Femto base station router 1, for example with mobile network 3 in other user terminals communicate.
More current the technical scheme that realize that user terminal and other user terminals in Femto cells communicate proposed.In a kind of prior art scheme, the user terminal in the Femto cell uses the number of self to communicate.In another kind of prior art scheme, the user terminal in the Femto cell all uses the number of the base station of this Femto cell to communicate.
Summary of the invention
Above-mentioned two kinds of technical schemes have shortcoming separately, particularly when the Femto base station is the enterprise that belongs to specific.
In first kind of prior art scheme; User terminal in the Femto cell uses the number of self; For example international mobile subscriber identity of user terminal (IMSI) or mobile user comprehensive service digital net number (MSISDN); Communicate, this means user terminal in communication as personal user rather than group user, such as the user of enterprise.Yet, enterprise generally all hope its employee's user terminal belong in access behind the Femto base station of enterprise can be as the member of enterprise but not the individual treat.First kind of technical scheme can't satisfy this demand of enterprise.
In second kind of prior art scheme, the user terminal in the Femto cell all uses the number of the base station of this Femto cell to communicate.Thus, when the incoming call request arrived the Femto base station, all user terminals in the Femto cell all can be called out.Obviously, this can not satisfy requirement of enterprise because can't distinguish different user terminals for the incoming call request, and this be for enterprise customer institute unacceptable.In addition, because user terminal uses same number,, and can't select to communicate with one's own name so user terminal is merely able to communicate as the member of enterprise.Thereby second kind of technical scheme possibly be suitable for the situation that the Femto base station belongs to specific family, but is unpractical for enterprise.
Therefore, a task of the present invention provides a kind of Femto cell solution, and this solution is particularly suitable for the enterprise customer.In this technical scheme; User terminal in the Femto cell is assigned unique extension (extension number); And use in this unique extension and this sub-district or this sub-district outside other user terminals communicate, as calling party or callee.And; The session of the user terminal in the Femto cell is all by Femto base station agency (proxied); This make user terminal self number for example IMSI or the MISISDN of user terminal all be its other side can not examine knowledge, thereby realized user terminal as group user but not the individual communicate.It should be noted that in the present invention the number of user terminal self and/or the number of base station also are called as termination number, so that be different from extension.
Preferably, this technical scheme also provides such option, if needs are promptly arranged, the user terminal in the Femto cell can use termination number to communicate, for example when enterprise staff hopes to carry out the privacy communication as the individual.
According to an aspect of the present invention; A kind of method for communicating that in femto cell base station, is used for is provided; It may further comprise the steps: i. sets unique extension to the user terminal of each mandate, and wherein, the user terminal of said mandate is the user terminal that is allowed to access this base station; Ii. when user terminal attempts to insert this base station, verify whether this user terminal is the user terminal of authorizing, if then allow this user terminal to insert this base station; Iii. receipt of call request, and according to the extension that sets the business in the said call request is transferred.
Preferably, step I comprises, the user terminal of said mandate is registered, and the termination number of the user terminal of storage registration, and said step I i verifies based on the termination number of said user terminal whether said user terminal is the user terminal of authorizing.
An advantage of the invention is thus: the extension of authorizes user terminal is to be set by the base station of Femto cell; And the log-on message of authorizes user terminal such as its termination number are also stored and are managed by femto cell base station, so these information of authorizes user terminal can safety and reliability ground storage and management.For example; When femto cell base station belongs to specific enterprise; This femto cell base station also generally is positioned at this enterprise; Thereby the personnel that only can get into this enterprise can be near this femto cell base station, and this enterprise can also wait the fail safe of guaranteeing the information in this femto cell base station such as fire compartment wall is set through multiple safe practice means.
Preferably, step I ii comprises: a. receive from first user terminal that does not insert this base station, to first call request of this base station; B. in response to said first call request, be created in first session between this base station and said first user terminal; C. receive first extension from said first user terminal; D. find out termination number corresponding to second user terminal of said first extension; E. judge whether said second user terminal inserts this base station; If f. said second user terminal inserts this base station; Then be created in second session between this base station and second user terminal; And between said first session and said second session, transfer, with swap data between first user terminal and second user terminal.
Thus, another advantage of the present invention is: for the incoming call request, different user terminals can be distinguished through extension in the Femto base station; And; Because the session between call subscriber terminal and the called user terminal is transferred through the Femto base station; Be that call subscriber terminal has only been set up session with the Femto base station; And do not set up direct session, so the sign that can hide called user terminal self to call subscriber terminal its termination number for example with called user terminal.
Preferably, said step I ii also comprises: A. receives second call request of the 3rd user terminal of this base station of access of controlling oneself; B. in response to said second call request, be created in the 4th session between this base station and said the 3rd user terminal; C. differentiate the type of the called number in said second call request; If D. said called number belongs to the number outside the extension, the termination number that then uses this base station is initiated new call request to mobile core network, thereby is created in this base station and corresponding to the 5th session between the terminal, four-function family of said called number; E. between said the 4th session and said the 5th session, transfer, with swap data between the 3rd user terminal and terminal, four-function family.
Thus; Another advantage of the present invention is: when the user terminal in the Femto cell is called out; The Femto base station is not created in the session between this user terminal and the called user terminal, and is to use the termination number of this Femto base station to be created in the session between Femto base station and the called user terminal, thereby; For called user terminal, this calling comes from the Femto base station.In other words, the user terminal in the Femto cell is that conduct is with this corresponding group user in Femto base station but not the individual carries out call business.
Preferably, whether after said steps A, carry out following steps before the said step B: differentiating said second call request is the direct calling request; If said second call request is the direct calling request; Then this second call request is transmitted to mobile core network, thereby directly is created in said the 3rd user terminal and corresponding to the session between the user terminal of the said called number in said second call request; If said second call request is not the direct calling request, then proceed said step B and step afterwards.
Thus, another advantage of the present invention is: if needs are arranged, the user terminal in the Femto cell can be selected to call out as group user or as the personal user.
According to another aspect of the present invention; A kind of business proxy device of communicating by letter of in femto cell base station, being used to is provided; It comprises: configuration module; Be used for setting unique extension to the user terminal of each mandate, wherein, the user terminal of said mandate is the user terminal that is allowed to access this base station; Authentication module is used for when user terminal attempts to insert this base station, verifies whether this user terminal is the user terminal of authorizing, if then allow this user terminal to insert this base station; Interconnecting module is used for the receipt of call request, and according to the extension that sets the business in the said call request is transferred.
