Description

Network attachment method and device

Technical field

The embodiments of the present invention relate to the field of communications, and in particular, to a network attachment method and apparatus.

Background technique

The network attachment is a registration process of the terminal device in the network before the actual operation of the network device. The terminal device can receive data sent from the network device only after the network is successfully attached. In the Long Term Evolution (LTE) system, the network attach request message sent by the terminal device to the network device includes an Evolved Packet System Session Management information transfer flag (ESM flag). When the ESM flag is 1, the terminal device specifies that the network device uses the Evolved Packet System Session Management (ESM) information indicated by the terminal device to establish a default bearer for the terminal device, where the default bearer is a type of satisfaction. The default QoS (Quality of Service) data and signaling user bearer provides the user with a permanent online transmission service. When the ESM flag is 0, the terminal device does not specify ESM information, and the network device needs to allocate the terminal device. ESM information, and use the ESM information to establish a default bearer for the terminal device. The ESM information includes information such as an Access Point Name (APN) and an authentication type. In order to reduce the signaling interaction between the terminal device and the network device and reduce the burden on the network device, the network operator usually requires the terminal device to set the ESM flag to 1.

The schematic diagram of the existing network attachment method is shown in FIG. 1. When the terminal device replaces the Subscriber Identity Module (SIM) card, the network of the operator where the terminal device is located changes, and the terminal device replaces the SIM card. After the first time the LTE network is started to be registered, the modem device directly initiates the network attach process after the initialization of the modem device (Modem) is completed, and notifies the application processing of the terminal device. The application processor (AP) performs a series of APN database creation for the terminal device to match the APN corresponding to the current SIM card. Therefore, the Modem initiates the network attach process earlier than the AP is the process in which the terminal device matches the APN corresponding to the current SIM card, and the network attach request initiated by the Modem still carries the information of the APN corresponding to the previous SIM card. If the APN corresponding to the previous SIM card is the same as the APN corresponding to the current SIM card, that is, the two SIM cards belong to the same carrier, the network attachment process can be performed normally; if the APN corresponding to the previous SIM card Different from the APN corresponding to the current SIM card, that is, two SIM cards do not belong to the same carrier, which may cause network attachment failure.

Or other similar communication systems.

Taking an LTE system as an example, FIG. 2 is a structural diagram of an LTE system according to an embodiment of the present invention. The LTE system is divided into two network elements, an Evolved Packet Core (EPC) device and an evolved Node B (eNode B). The EPC is responsible for the core network part, including the Mobility Management Entity (MME) and the Serving Gateway (S-GW), wherein the MME performs signaling processing and the S-GW performs data processing. The eNode B is responsible for the access network portion, also known as the Evolved Universal Terrestrial Radio Access Network (E-UTRAN). EPC and Node B can be collectively referred to as network devices.

In various scenarios, it can also be used in various scenarios where the ESM flag is 0. Generally, the information of the ESM flag is stored in the SIM card. When the modem is initialized, the modem sends a first APN request message to the AP, so that the AP acquires the configuration file of the first APN according to the first APN request message. During the process of obtaining the configuration file of the first APN, the AP first reads the ESM flag in the SIM card. Therefore, when the ESM flag is 0, the AP does not need to perform the subsequent steps, and the result of the ESM flag being 0 is returned to the modem. The modem does not need to carry the configuration file of the first APN in the network attach request message, and the network device can be the terminal. The device allocates an APN and establishes a default bearer for the terminal device. When the ESM flag is 1, the AP can obtain the configuration file of the first APN and the first APN after determining that the ESM flag in the SIM card is 1. The first APN is the APN corresponding to the current SIM card of the terminal device, and is sent. The network attach request message to the network device, the network attach request message includes at least the configuration file of the first APN, so that the network device can establish a default bearer by using the APN corresponding to the current SIM card of the terminal device, and the terminal device is prevented from performing network attachment. When the APN used by the AP and the AP are different for the terminal device, the signaling interaction between the terminal device and the network device is reduced, the burden on the network device is reduced, and the success rate of the network attachment is improved.

In addition, the terminal device described in this embodiment of the present invention may be a wireless terminal or a wired terminal, and the wireless terminal may be a device that provides voice and/or data connectivity to the user, a handheld device with wireless connection function, or a connection. Other processing devices to the wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (eg, RAN, radio access network), which can be a mobile terminal, such as a mobile phone (or "cellular" phone) and with a mobile terminal The computers, for example, can be portable, pocket-sized, handheld, computer-integrated or in-vehicle mobile devices that exchange language and/or data with the wireless access network. For example, personal communication service (PCS) telephone, cordless telephone, session initiation protocol (SIP) telephone, wireless local loop (WLL) station, personal digital assistant (PDA), etc. . A wireless terminal may also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile station. Mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, terminal User device, or user equipment. The network device mentioned in the embodiment of the present invention may be a hardware device, such as a base station, a router, or a hub, which is generally used for remotely accessing network resources, and is not specifically limited in this embodiment of the present invention.

It should also be noted that the term “and/or” in this context is merely an association relationship describing an associated object, indicating that there may be three relationships, for example, A and/or B, which may indicate that A exists separately and exists at the same time. A and B, there are three cases of B alone. In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship.

An embodiment of the present invention provides a network attachment method, where the method is applied to a terminal device, where the terminal device includes a modem and an AP, as shown in FIG. 3 . Specifically, the network attachment method includes:

S101. When the Modem is initialized, the Modem sends a first access point name APN request message to the AP.

When the terminal device is powered on for the first time after the device is powered on or replaced for the first time, the network corresponding to the SIM card of the terminal device may change. In order to improve the success rate of network attachment, during the initialization of the modem, the Modem will The AP sends a first APN request message, where the first APN is an APN corresponding to the SIM card of the terminal device.

Further, the Modem initialization refers to the initialization process that the Modem first performs before the terminal device is powered on for the first time or after the terminal device replaces the SIM card for the first time, and before the Modem sends the network attach request message to the network device. In the prior art, the Modem not only informs the AP to perform APN matching after the initialization of the Modem is completed. In the present invention, by designing the internal timing of the terminal device, when the Modem is initialized, The modem can send a first APN request message to the AP.

It should be noted that, because the time required for the initialization of the modem is much longer than the time for the APN to be matched by the AP, the modem can obtain the configuration file of the first APN sent by the AP before the initialization of the modem is completed. The signaling interaction between the device and the network device reduces the burden on the network device and improves the success rate of the network attachment.

S102. The AP acquires a configuration file of the first APN according to the first APN request message.

Specifically, as shown in FIG. 4, step S102 may include steps S102a and S102b:

S102a: The AP acquires the first APN according to the first APN request message, where the first APN is an APN corresponding to the customer identity identification SIM card of the terminal device.

Specifically, as shown in FIG. 5, step S102a may include steps S102aa and S102ab:

S102aa, the AP obtains the network identifier of the SIM card from the SIM card.

The network identifier of the SIM card is a combination of any one or more of a first identifier, an international mobile subscriber identity (IMSI), and an integrated circuit card identity (ICCID), where One is identified as Mobile Country Code (MCC) and Mobile Network Code (MNC).

IMSI is a logo that distinguishes mobile users and is stored in the SIM card and can be used to distinguish valid information of mobile users. The ICCID is fixed in the SIM card of the terminal device and is used to identify the unique identification number of the IC card. The MCC is an identity that is uniformly assigned and managed by ITU to uniquely identify the country to which the mobile subscriber belongs. The MNC is used to identify the mobile network to which the mobile customer belongs. The MCC consists of three decimal digits. For example, the MCC of China is 460, the MCC of the United States is 310, and the MCC of the United Kingdom is 234. The MNC is generally composed of two or three decimal digits. For example, China Mobile's MNC is 00. 02, 04 and 06, China Unicom's MNC is 01, 05, 07, and China Telecom's MNC is 03.

The combination of MCC and MNC can uniquely identify the network operator corresponding to the SIM card. For example, 46000 is China Mobile, 45400 is Hong Kong Telecom, and 46697 is Taiwan Big Brother.

It should be noted that the first identifier, the IMSI, and the ICCID are used to identify the terminal design. Prepare the parameters of the network to which the current SIM card belongs. The network identifier of the network to which the current SIM card belongs to the terminal device provided by the embodiment of the present invention is not limited to the above-mentioned parameters, and the remaining parameters that can identify the network to which the current SIM card belongs to the terminal device are also not limited by the present invention.

The S102ab and the AP obtain the first APN corresponding to the network identifier of the SIM card according to the network identifier of the SIM card.

The mapping between the network identifier of the SIM card and the APN in the AP may also be referred to as the configuration information of the APN.

It should be noted that the correspondence between the network identifier of the SIM card and the APN is preset in the terminal device, and the correspondence information between the network identifier of the SIM card and the APN may be a set of data, or may be a list. The form is stored inside the terminal device. Specifically, the network identifier of one SIM card may correspond to multiple APNs. Preferably, the network identifier of the SIM card is in one-to-one correspondence with the APN. The terminal device uses the APN corresponding to the network identifier of the network to which the current SIM card of the terminal device belongs, and can ensure the success rate of the network attachment.

It should be noted that, if the network identifier of the SIM card and the network identifier of the SIM card in the correspondence information of the SIM card correspond to multiple APNs, the AP selects one APN from the multiple APNs as the first APN; The network identifier of the SIM card in the corresponding relationship information of the identifier and the APN is in one-to-one correspondence with the APN, and the AP directly obtains the APN corresponding to the network identifier of the network of the current SIM card of the terminal device as the first APN.

Further, the network identifier and the APN corresponding relationship information of the SIM card mentioned in the embodiment of the present invention may include not only the APN, but also the APN password, the user name, the Internet Protocol (IP) type, and the authentication. Information such as type, the invention is not limited.

It is to be noted that if the ESM flag in the SIM card is 0, the AP does not need to perform the step S102, and the result of the ESM flag being 0 is returned to the Modem, and the Modem does not need to carry the configuration file of the first APN in the network attach request message. The network device can allocate an APN for the terminal device and establish a default bearer for the terminal device.

S102b: The AP acquires a configuration file of the first APN according to the first APN.

Specifically, if the AP stores the configuration file of the second APN and the second APN, where The second APN is an APN of the network that the terminal device accesses before the Modem is initialized. As shown in FIG. 6, step S102b may include steps S102ba-S102bc:

S102ba: The AP confirms whether the first APN is the same as the second APN.

S102bb. If the first APN is the same as the second APN, the AP acquires the configuration file of the second APN stored in the AP, and sets the configuration file of the second APN as the configuration file of the first APN.

If the first APN is the same as the second APN, the network to which the current SIM card belongs is the same as the network that the terminal device accesses last time. For example, the network to which the current SIM card belongs is China Mobile, and the network that the terminal device accesses last time. Also for China Mobile, the AP obtains the configuration file of the second APN stored in the AP, and sets the configuration file of the second APN as the configuration file of the first APN.

S102bc: If the first APN is different from the second APN, the AP generates a configuration file of the first APN according to the first APN.

If the first APN is different from the second APN, the network to which the current SIM card belongs is different from the network that the terminal device accesses last time. For example, the network to which the current SIM card belongs is China Mobile, and the network that the terminal device accesses last time. For China Unicom, the AP needs to generate a configuration file of the first APN according to the first APN.

Specifically, the AP generates a configuration file of the first APN according to the first APN, and the AP generates a profile file of the first APN according to the first APN.

S103. The AP sends a configuration file of the first APN to the Modem.

S104: The Modem sends a network attach request message to the network device, where the network attach request message includes at least a configuration file of the first APN, where the network attach request message is used to trigger the network device to establish a default bearer with the terminal device according to the configuration file of the first APN.

After receiving the configuration file of the first APN sent by the AP, the modem sends a network attach request message to the network device, so that the network device establishes a default bearer with the terminal device according to the configuration file of the first APN.

S105. The Modem receives a network attach complete message sent by the network device.

The network attachment request message sent by the modem is carried by the first APN. The file is set up, and the first APN is an APN corresponding to the network identifier of the network to which the current SIM card belongs to the terminal device, so that the success rate of the network attachment is high, and the APN is not rejected or detached. Therefore, the terminal device successfully registers once, which greatly reduces the load of the network and reduces signaling interaction between the terminal device and the network device.

Further, as shown in FIG. 7, the network attachment method provided by the embodiment of the present invention may further include steps S106 and S107:

S106: After the network detach request message is sent to the network device, the Modem sends a first APN deletion message to the AP.

Optionally, when the terminal device is powered off or the card is replaced again, the Modem sends a network detach request message to the network device, and the Modem also sends a first APN delete message to the AP. Then, in this case, the configuration file of the second APN and the second APN will no longer be stored in the AP.

S107. The AP deletes the configuration file of the first APN according to the first APN deletion message.

It should be noted that, after the terminal device completes the network attachment, if the user manually switches the APN or the APN changes, the Modem can also confirm whether the changed APN is the same as the first APN, and if the changed APN is the same as the first APN. The terminal device does not perform the subsequent steps; if the changed APN is different from the first APN, the AP generates a configuration file of the changed APN, and sends the changed APN configuration file to the Modem, so that the Modem initiates the detach process. And re-establish network attachment using the changed APN configuration file.

The embodiment of the present invention provides a network attachment method, which is applied to a terminal device, where the terminal device includes a Modem and an AP. When the Modem is initialized, the Modem sends a first access point name APN request message to the AP; the AP according to the first APN request message.

Based on the description of the above embodiment, due to Modem The first APN request message can be sent to the AP when the modem is initialized, so that after receiving the first APN request message, the AP acquires the configuration file of the first APN according to the first APN request message, and the first APN is obtained. The configuration file is sent to the modem, and then the modem sends a network attach request message to the network device. The network attach request message includes at least the configuration file of the first APN, so that the network device can use the current client identity of the terminal device to identify the APN corresponding to the SIM card as the terminal device. Establishing a default bearer, which avoids the case where the APN used by the terminal device to perform network attachment is different from the APN that the AP matches for the terminal device, reduces the signaling interaction between the terminal device and the network device, and reduces the burden on the network device.
