Description
Technical field
The invention belongs to moving communicating field, relate in particular to a kind of mobile communication home use indoor base station and insert and management method.
Background technology
Regulation according to ITU (International Telecommunications Union), 3-G (Generation Three mobile communication system) (3G) is operated in 2000MHz or above frequency, therefore because higher than second generation mobile communication system (2G) operating frequency, wavelength is shorter, make the diffraction and the penetration capacity of radio wave weaken, space loss is bigger, and the signal that therefore how to reach 3-G (Generation Three mobile communication system) effectively effectively covers, to the user provide at any time, everywhere 3G (Third Generation) Moblie service brought challenge; Secondly 3G (Third Generation) Moblie requires to provide the radio multimedium service in high speed, broadband to the user, therefore supports multi-user's high speed, broadband wireless business and power system capacity to bring challenge to limited frequency spectrum resources; High speed wireless data is professional to be designed in order to satisfy owing to 3G (Third Generation) Moblie, according to the abundant operation experience of second generation mobile communication system and the business statistics of 3G (Third Generation) Moblie, the business above 70% in 3-G (Generation Three mobile communication system) will occur under the indoor environment.
Based on this, the notion of home use indoor base station (HNB) quietly rises.Its place that is different from mobile communications network is: support that Uu air interface, the cable port of 3-G (Generation Three mobile communication system) are the core net that is linked into 3-G (Generation Three mobile communication system) by indoor existing broadband network.Restriction, mobile subscriber that this kind structure has solved indoor environment can obtain the mobile broadband multimedia service in the indoor resource that exclusively enjoys.Because home use indoor base station is the indoor equipment at the domestic consumer, its quantity is very huge.Therefore can not continue to use the way to manage of general telecommunications access device, its access-in management also needs to consider again.
3-G (Generation Three mobile communication system) mainly is to transmit information by the prior mobile network structure base station equipment is directly managed to the management method of base station equipment access at present.This kind access-in management framework is fit to existing mobile radio communication.Single from interface, home use indoor base station itself has been a kind of IP network terminal equipment.Therefore also should remove to consider authentication question, shown in the authentication management of IP device general (as Fig. 1) from the angle of IP device management.
For the equipment on the IP network, both can carry out authentication management by the mode of dynamic host configuration server (DHCP Server), also can carry out authentication management by increasing an extra flow process.If the scheme by DHCP Server is carried out authentication management, then require Internet Protocol (IP) address of terminal equipment to distribute by DHCP Server.Its process is: when equipment initially powers on (resetting), to the corresponding application IP addresses request of all Dynamic Host Configuration Protocol server broadcasting (being Dynamic Host Configuration Protocol server clean culture when resetting) of this locality, wherein carry user's relevant authentication information (by the Option field in the dhcp message) with at first in this request to a certain appointment.After Dynamic Host Configuration Protocol server is received this application IP addresses request,, after passing through, authentication will distribute corresponding IP address to the user with at first equipment being authenticated according to the authentication information that provides in the request message and local other relevant information of preserving.
Operator just only carries out safety certification (authentication mode has PPPOE, DHCP+WEB and 802.1x) in the access bearer aspect to the broadband user.For general family expenses IP network equipment, operator does not manage.Why will carry out its reason of authentication management to home use indoor base station equipment is: though be an IP terminal equipment on the home use indoor base station surface, but belong to the carrier class business device, need guarantee it safe legitimacy, prevent that malice from inserting, to safeguard the safety of other telecommunications gateway device.
At the family expenses indoor base station not under the situation of integrated router function, be that home use indoor base station is when being linked into home router, because the reality that the IP address is rare, operator may take directly to distribute the mode of private IP address (as Figure 10 to home use indoor base station by home router, DSLAM is the ADSL couple in multiplexer among the figure, and BRAS is a BAS Broadband Access Server).Be the role that home router has been served as unique Dynamic Host Configuration Protocol server.Even at this moment adopt dhcp message to carry the method for parameters for authentication, then also can only by home router be finished for the authentication management of home use indoor base station this moment as can be known.But authenticate the legitimacy that another will be linked into the household equipment in the communication network by one family equipment (home router), this does not obviously conform to actual.Therefore under the situation that private IP address is distributed, can only adopt the form that increases extra identifying procedure to carry out for the authentication management of home use indoor base station equipment.
Disposed IPV6 (IP address sixth version) or home use indoor base station itself integrated during router feature, home use indoor base station will be assigned with public ip address.Under this scene, can in the DHCP Server that distributes publicly-owned address to base station from home, carry out, also can on newly-increased specific authentication management server, carry out for the authentication management of base station from home.If but at this moment adopted the specific authentication flow process that home use indoor base station is authenticated, influence obviously could be reduced to existing IP device authentication management system.
In sum as can be known, no matter be for public ip address allocation scenarios or privately owned address allocation scenarios, can adopt the authentication management of home use indoor base station increases the form that extra flow process authenticates.For taking into account the use of these two kinds of address distribution, must adopt the mode that home use indoor base station is carried out independent authentication management simultaneously.
Therefore, solve the access way of home use indoor base station and the management method after the access, become the important topic that 3-G (Generation Three mobile communication system) must be faced.
Summary of the invention
