Background
With the development of smart phones, in order to meet the needs of operators, the phones have implemented a function of establishing multiple PDN (packet data network) connections at the same time. The PDN connection is an IP (internet protocol) connection provided by an EPS (evolved packet system) system between a mobile phone and an external packet data network (PLMN) of a Public Land Mobile Network (PLMN). In PDN connection, UE is identified by an IP address, and PDN is identified by an APN (access point network). In a simple aspect, the PDN may be considered as the Internet, and the mobile phone accesses the corresponding PDN network through the designated APN, and after establishing the PDN connection, allocates an IP address to the mobile phone, thereby implementing the network access by the mobile phone.
In the existing scheme, the multiple PDNs are established in the following ways: and matching APN configuration files of an AP (Access Point) side according to the APN type corresponding to the application in the mobile phone, and initiating dialing. For example, the mobile phone supports 4 PDNs, and the corresponding APN names are inteneat, admin, ims, and thermal, respectively; after the connection is established, the mobile phone defaults to dial by using APN corresponding to Internet, and PDN connection is established; when an application related to ims needs to access the network, the AP searches APN with name of ims in the APN configuration file, and initiates dialing and establishes PDN connection.
The prior art has at least the following problems: on one hand, after the AP initiates a data dialing request, before the data dialing request is responded, instructions such as a telephone or a short message are blocked according to the existing socket communication mechanism, and the mobile phone cannot communicate by using functions such as the telephone and the short message; on the other hand, if a network handover occurs, for example, a handover from LTE (long term evolution) to HRPD (high rate packet data), the AP side is required to disconnect the network and redial. The above situation may cause the communication of the user to be interrupted or not normally performed, and the user experience is affected.
Disclosure of Invention

101. the function module receives a dialing request sent by the access point.
102. And the functional module acquires the access point network name and the access point network type according to the dialing request, and establishes PDN data connection with the network side by using the access point network name, the access point network type and the registered network type of the terminal.
Wherein the obtaining of the access point network name and the access point network type according to the dialing request includes:
the function module inquires an access point network configuration table according to an access point network identifier included in the dialing request, and acquires an access point network name and an access point network type, wherein each access point network identifier in the access point network configuration table corresponds to one access point network type and one access point network name; or,
and the functional module directly obtains the corresponding access point network type according to the access point network name included in the dialing request.
103. And after the PDN data connection is successfully established, the functional module sends the network protocol IP address and the network type of the terminal in the PDN data connection to the access point.
Further, the method further comprises:
the functional module receives a disconnection request sent by the access point, wherein the disconnection request comprises the network identifier of the access point, the name of the access point or indication information; and the functional module disconnects the corresponding PDN data connection according to the access point network identification or the access point name, or disconnects all PDN data connections according to the indication information.
Further, when the network type registered by the terminal changes, the functional module establishes a new PDN data connection according to the current network type, the access point network name, and the access point network type; and after the new PDN data connection is successfully established, the functional module sends a switching message, a new IP address and a new network type to the access point.
Further, after the sending the network protocol IP address and the data connection type to the access point, the method further comprises:
if the PDN data connection is failed to be established, the functional module sends an establishment failure message to the access point; the functional module reestablishes the PDN data connection.
Compared with the prior art that the data dialing is initiated by the AP side, the embodiment of the invention arranges the functional module in the terminal, and assists the AP in the terminal to establish the PDN data connection of the packet data network with the network side through the functional module. The function module receives a dialing request sent by an access point; the function module acquires an access point network name and an access point network type according to the dialing request, and establishes PDN data connection with a network side by using the access point network name, the access point network type and the registered network type of the terminal; and after the PDN data connection is successfully established, the functional module sends the network protocol IP address and the network type of the terminal in the PDN data connection to the access point. After the functional module is added, the functional module replaces the AP to interact with the RIL (radio interface layer), and the AP can be considered not to perform instruction interaction with the RIL; therefore, the RIL can process instructions sent by other services, so that the normal operation of other services is not influenced by the establishment of PDN data connection, and the service processing efficiency is improved. In addition, when the network type is switched, only the functional module is required to interact with the network side, and the AP is not required to process, so that the network interruption of a user is avoided, and the user experience is improved.
Another embodiment of the present invention provides a method for implementing a multi-packet data network, which is applied to a terminal, where a function module is set in the terminal, and an access point AP in the terminal is assisted by the function module to establish a PDN data connection with a network side, as shown in fig. 2, where the method includes:
201. the function module is initialized.
202. The function module receives an access point network identifier (APNid), an access point network type (APNtype) and an access point network name (APNname) sent by the AP.
Wherein, the APNid, the APNtype and the APNname are preset in the mobile phone of the user according to the requirement of an operator. The APNname is generally stored in an HLR (home location register) as user subscription data, and a user mobile phone may also provide an APN to a network side when initiating a packet data service, so that the network side selects a GGSN (gateway gprs support node) to which the user mobile phone should access and determines to access a corresponding external network by the GGSN. In addition, a wildcard may be stored in the HLR so that the subscriber or SGSN may choose to access an APN not stored in the HLR. For example, in the current network, APN = cmnet represents internet, and APN = cmwap represents a dedicated WAP (wireless application protocol) data network, and the network names corresponding to the operators are different, for example, the link is uniwap, uninet, and the like.
Alternatively, the AP may send only the access point network type APNtype and the access point network name APNname to the function module.
203. The function module generates an access point network configuration table according to the access point network identification, the access point network type and the access point network name.
For example, the generated access point network configuration table is shown in table 1,
table 1:
| APN id | APN type | APN name |
| 1 | IPV4/IPV6 | Internet |
| 2 | IPV4/IPV6 | Admin |
| 3 | IPV4/IPV6 | IMS |
| 4 | IPV4/IPV6 | Tethering |
the configuration table is stored at the side of the function module, and when the AP needs to perform data dialing and establish data connection with the PDN, the AP sends a dialing request to the function module.
204. The function module receives a dialing request sent by the AP.
Wherein, the dialing request includes APNid or APNname.
205. And the functional module matches the corresponding APNname and APNtype in the access point network configuration table according to the dialing request.
206. And the functional module initiates the establishment of data connection with the PDN according to the network type registered by the mobile phone and the matched APNname and APNtype.
It should be noted that the function module may replace the AP to perform functions such as data dialing until data connection is established, and the AP side only needs to send the APNid or APNname corresponding to the PDN network to be connected to the function module. This procedure reduces the operations on the AP side, and the AP does not have to wait for the response message of the data dialing request to be sent. Because a socket communication mechanism is used between the existing Android architecture and the RIL, namely, before an AP initiates a data dialing request and a response is not obtained, commands such as short messages and calls of a mobile phone are blocked, and normal communication cannot be executed. The functional module is adopted to replace the AP for data dialing, so that the problems can be solved, and the smooth communication of the mobile phone is ensured.
The network type of the mobile registration includes LTE, EHRPD, EVDO (evolution data optimized), and the like. It can be considered as different types of networks such as 2G/3G/4G.
207. And if the data connection is successfully established, the functional module sends the acquired IP address and the network type to the AP.
Optionally, after the data connection is successfully established, if a network switch occurs in the mobile phone, for example, a 2G network is switched to a 3G network, the mobile phone needs to be reconnected to the PDN network. In this embodiment, the function module may obtain the current network type, and execute step 206 again to reestablish data connection with the PDN network, report a message for switching networks to the AP, and report a new IP address and the current data connection type to the AP. However, in the prior art, if the AP dials data, the AP side needs to disconnect the data connection first and then dial again, which may affect the normal network access of the user. Compared with the prior art, the mobile phone network switching method has the advantages that the functional module is arranged, so that the continuity of data connection can be guaranteed when the mobile phone switches the network, the stability of a user accessing the network is improved, and the user experience is improved.
Optionally, if the data connection is failed to be established, the functional module reestablishes the data connection after the preset condition is met. The preset condition may be a condition that a time threshold is met or a request for reestablishing the data connection is received from the AP, for example, the condition that the time threshold is met may be that the data connection is reestablished after an interval of 3 seconds.
Optionally, after the data connection is successfully established, the functional module may receive a network disconnection request sent by the AP, where the network disconnection request is an instruction issued by a user to the mobile phone, and the user wants to disconnect the current data connection due to some requirement; the function module disconnects the one or more data connections upon receiving the request. The network disconnection request can carry one or more APNids, and the functional module disconnects the corresponding data connection according to the APNids; or the network disconnection request carries indication information or does not carry any information, and at the moment, the functional module disconnects all data connections according to the network disconnection request.
Compared with the prior art that the data dialing is initiated by the AP side, the embodiment of the invention arranges the functional module in the terminal, and assists the AP in the terminal to establish the PDN data connection of the packet data network with the network side through the functional module. The function module receives a dialing request sent by an access point; the function module acquires an access point network name and an access point network type according to the dialing request, and establishes PDN data connection with a network side by using the access point network name, the access point network type and the registered network type of the terminal; and after the PDN data connection is successfully established, the functional module sends the network protocol IP address and the network type of the terminal in the PDN data connection to the access point. After the functional module is added, the functional module replaces the AP to interact with the RIL, and the AP is considered not to perform instruction interaction with the RIL; therefore, the RIL can process instructions sent by other services, so that the normal operation of other services is not influenced by the establishment of PDN data connection, and the service processing efficiency is improved. In addition, when the network type is switched, only the functional module is required to interact with the network side, and the AP is not required to process, so that the network interruption of a user is avoided, and the user experience is improved.
