Embodiment
In order to make 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.
The present invention can be divided into two big classes with the external network that portable terminal inserts: the network that a class provides for operator, as: WAP and Internet; Another kind of is the privately owned net of enterprise, as the privately owned net of banking system.
The present invention provides a fixing APN number for all portable terminals, rather than distributes different APN number according to the packet network that inserts.When portable terminal will insert packet network, for portable terminal is provided with a user name, there is a sign in this user name, this sign is corresponding one by one with the packet network supplier who is inserted, as mobile terminal user David@BANKNAME by name is set, then this user name is corresponding with the BANKNAME private network; Mobile terminal user David@MCPNAME by name is set, then this user name is corresponding with the network that mobile operator provides, the Internet network that provides for mobile operator that inserts as for portable terminal still be the WAP network, then according to portable terminal the network destination address that inserted is set or the protocol type of setting determines.
As shown in Figure 2, Fig. 2 is the flow chart of portable terminal access packet network process of the present invention, and its concrete steps are:
Step 202, insert when parsing that the Username-APN of packet network represents for private network the time, GGSN distributes to IP address of portable terminal and inserts this private network according to this Username-APN; During the network that provides for mobile operator that inserts when parsing that the Username-APN of packet network represents, GGSN distributes to IP address range of this portable terminal according to the fixedly APN that portable terminal distributes, in this IP address range, give this mobile terminal IP address by the GGSN dynamic assignment, and insert the network that mobile operator provides according to Username-APN, be linked into WAP or the Internet that mobile operator provides according to the visit purpose network address or the purpose procotol that portable terminal sets again.
When portable terminal inserted packet network, packet network can also carry out authentication to portable terminal, and portable terminal could insert packet network by authentication.
Below the present invention is made specific description.
For the privately owned net of enterprise, mobile phone users is provided with unified APN name, mobile phone users is distinguished different access packet network suppliers by the mode that the different user name is set on portable terminal, user as the system of private company is provided with user David@COMPANYNAME by name, banking system user is Jene@BANKNAME, when mobile phone users carries out the data network visit, the username information that GPRS is adopted when landing according to mobile phone users, parse real APN at GGSN, be " COMPANYNAME " as parse real APN from David@COMPANYNAME, allow the private network of this COMEPANY of this user capture according to this APN.
Network for mobile operator oneself, mobile phone users is provided with unified APN and unified user name, this user name has shown that this portable terminal inserts the network that mobile operator provides, as: David@MCPNAME, parse real APN for mobile operator at GGSN, portable terminal utilizes prior art that the destination address of visit is set again or protocol type decision that visit is set inserts the heterogeneous networks that mobile operator provides.
But no matter be to be linked into which kind of network, the employed APN title of mobile phone users is one that fixes, as: be set to " SingleAPN ".This APN title will be used as that HLR opens an account, unique APN is managed for configuration in the DNS database, greatly facilitates the maintenance management of HLR and DNS.
When portable terminal will insert packet network, GGSN distributed an IP address must for this portable terminal.If mobile phone users uses fixing APN name, how the IP address of mobile phone users is distributed?
For the mobile phone users of visit enterprise private network, the IP address assignment mode of mobile phone users and distribution address pool are by this enterprise's decision.GGSN obtains real Username-APN by resolving user name in the reality operation, and this APN directly can represent and distinguish different enterprises.Therefore address distribution and distribution address pool tissue can be configured according to the Username-APN that user name parses.For example: as the user Jene@BANKNAME by name that mobile phone users is provided with, the Username-APN that GGSN parses is BANKNAME, then distributes to IP address of this portable terminal according to this BANKNAME by GGSN.
Mobile phone users for visit packet network that mobile operator provides, because mobile operator not only provides a packet network to mobile phone users, mobile operator can provide a plurality of packet networks to portable terminal, so just can not give mobile phone users distributing IP address according to the Username-APN that GGSN parses.Mobile operator carries out the IP address configuration according to the fixing APN unification of allocating in advance to portable terminal to portable terminal, be that mobile operator distributes an IP address range according to APN, the address pool of promptly distributing this portable terminal place, dynamic assignment is given IP address of this portable terminal in this IP scope, as: when the APN of mobile phone users setting is APN1, it is 211.0.0.1～211.0.0.100 that GGSN distributes to IP address range of this portable terminal according to this APN1, and mobile phone users is given in IP address of dynamic assignment in this address realm.
Fig. 3 is the block diagram of the present invention's mobile phone users access different grouping network in GPRS network, in Fig. 3:
The APN that GPRS user A is set is SingleAPN1, when GPRS user A is provided with user David@COMPANYNAME by name, the activation request message that then has the SingleAPN1 of user A sends on the GGSN by base station sub-system and SGSN, GGSN parses Username-APN according to the user name David@COMPANYNAME among this user A that activates in the request message, be COMPANYNAME, COMPANYNAME has represented different enterprise network, give this user A configuration a fixed IP addresses according to this COMPANYNAME by GGSN, and be connected with this enterprise network, promptly private company's private network connects.
The APN that GPRS user A is set is SingleAPN1, when GPRS user A is provided with user David@MCPNAME by name, then having the user name David@MCPNAME of user A and the activation request message of SingleAPN1 sends on the GGSN by base station sub-system and SGSN, GGSN parses Username-APN according to the user name David@MCPNAME among this user A that activates in the request message, be MCPNAME, the network that on behalf of mobile operator, MCPNAME provide, the packet network that provides for mobile operator of access is provided according to MCPNAME, GGSN distributes an IP address for user A according to the SingleAPN1 that activates this user A in the request message, user A is connected in the network that mobile operator provides, determines to be connected to WAP or the Internet that mobile operator provides according to the destination address of the set visit of user A or the protocol type of visit again.
The APN that GPRS user B is set is SingleAPN1, when GPRS user B is provided with user Jene@MCPNAME by name, then having the user name Jene@MCPNAME of user B and the activation request message of SingleAPN2 sends on the GGSN by base station sub-system and SGSN, GGSN parses Username-APN according to the user name Jene@MCPNAME among this user B that activates in the request message, be MCPNAME, the network that on behalf of mobile operator, MCPNAME provide, the packet network that provides for mobile operator of access is provided according to MCPNAME, GGSN distributes an IP address range for user B according to the SingleAPN1 that activates this user B in the request message, dynamic assignment is given IP address of user B in this IP address range, user B is connected in the network that operator provides, determines to be connected to WAP or the Internet that operator provides according to the destination address of the set visit of user B or the protocol type of visit again.
Before portable terminal inserts packet network, can carry out authentication to this portable terminal, after authentication is passed through, allow this portable terminal to insert packet network again.If each mobile phone users has a fixing APN, so how authentication is carried out in the request of mobile phone users access network?
When mobile phone users access enterprise private network, GGSN goes out Username-APN according to the mobile phone users name analysis, and this Username-APN authenticates to the authenticating device of corresponding network.
Fig. 4 is the authentication schematic diagram of mobile phone users access enterprise private network, in Fig. 4:
The Access Point Name that GPRS user is set is SingleAPN, when GPRS user A is provided with user David@COMPANYNAME by name, user cipher is AAA, the activation request message that then has the Access Point Name SingleAPN of user A sends to GGSN by base station sub-system and SGSN, GGSN parses Usernmame-APN according to the user name that activates this user in the request message, be COMPANYNAME, this COMPANYNAME has represented different enterprise network, COMPANYNAME is carried out authentication with corresponding private network certificate server, whether the user name David@COMPANYNAME and the user cipher AAA that promptly verify GPRS user be correct, if it is correct, then this user can insert private firm's private network, otherwise this user cannot insert private firm's private network.
When mobile phone users inserts the network that mobile operator provides, four kinds of optional different authentication methods can be arranged: first kind, insert Collective qualification by the advanced radius agreement according to the IP address of mobile phone users institute accesses network, be that authentication server receives that the authenticating result of returning after the authentication request of portable terminal is the network purpose IP address range that portable terminal allows the network purpose IP address range that inserts and do not allow to insert, if the network purpose IP address that portable terminal will insert is within the network purpose IP address range that allows to insert, then can insert this network, otherwise, cannot insert this network; Second kind, insert Collective qualification by the advanced radius interface according to the data pack protocol type that mobile phone users sent, be that authentication server is received the network protocol type of authenticating result for allowing the network protocol type that inserts and not allowing to insert of returning after the authentication request of portable terminal, if portable terminal is wanted the network protocol type of protocol type for allowing to insert of access network, then can insert this network, otherwise, cannot insert this network; The third, integrated RADIUS authentication server capability carries out mobile phone users access Collective qualification on GGSN, and in the authority of GGSN configuration portable terminal, the authority configuration can be disposed respectively by purpose IP address or protocol type; The 4th kind, the business that mobile phone users sent is disperseed authentication, if promptly portable terminal is wanted accesses network A, then carry out authentication to network A.
As shown in Figure 5, the schematic diagram of authentication embodiment when Fig. 5 inserts the mobile operator network for portable terminal, in the drawings:
GPRS user asks to insert certain network, GPRS user carries out access authentication on GGSN, GGSN sends authentication request to certificate server, this authentication request comprises GPRS user's APN number and user name password, authentication response is handled and sent to certificate server to GGSN after receiving this authentication request, comprise the purpose network title that this GPRS user allows the purpose network title that inserts and do not allow to insert in this authentication response, GPRS user inserts the purpose network that allows access by GGSN.
GGSN also can be in advance to GPRS user's authentication, and promptly not to GPRS user's APN number and user name cipher authentication, after GPRS user inserted packet network, directly the network that will visit to GPRS user disperseed authentication.As shown in Figure 5, when the GPRS user capture when the network of streaming media service is provided, carry out GPRS user's APN number and user name cipher authentication to the network that streaming media service is provided, if pass through, just allow visit; When the GPRS user capture be internet the time, carry out and the user name cipher authentication to the internet network APN number of GPRS user, if pass through, just allow visit; When the GPRS user capture when the network of multimedia short message service is provided, carry out GPRS user's APN number and user name cipher authentication to the network that multimedia short message service is provided, if do not pass through, just do not allow visit.
Method provided by the invention has reduced the complexity of carrier network configuration, does not need to revise the configuration data on all devices when inserting new packet network, and only need revise the configuration data of GGSN, has reduced operation cost; Method provided by the invention has reduced the complexity that is provided with in the network process on the mobile phone users, most of following of situation need be provided with a user name and just can enjoy all services that operator provides, in needs visit enterprise private network, the mode of landing by the switching user name realizes, reduces the configuration difficulty.
