Description

Network registration method and terminal device

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a network registration method and a terminal device. Background technique

In order to meet the increasing demands of users for mobile broadband and high data rate transmission, 3GPP began the Long Term Evolution (LTE) project of the Universal Mobile Telecommunications System (UMTS) technology. The circuit switching (CS) is eliminated in the LTE network, and the flat network architecture of the entire Internet protocol is adopted. In order to ensure that the Evolved Packet System (EPS) fully utilizes its own technological advantages, multiple bearer and processing mechanisms are introduced in the LTE network. In order to implement the always-on of the user equipment (UE), the LTE network is accompanied by the establishment of a packet data network (PDN) connection of the default bearer in the attach (also called registration) process.

An Access Point Name (APN) is used during the LTE Attach process to establish a default PDN connection. Depending on the network configuration, the default PDN connection is also established in the following ways:

Mode 1: The UE does not carry the APN parameter when performing LTE Attach. The APN parameter used is sent by the network side, and the APN establishes a default PDN connection to ensure the success of the LTE Attach.

Mode 2: The UE carries the APN parameter when performing the LTE Attach. At this time, the default PDN connection is established by using the APN parameter carried by the UE. In this mode, if the APN parameter carried by the UE is incorrect, the LTE Attach fails.

As shown in the above description, if the UE uses the wrong APN parameter for LTE Attach, the LTE network rejects the LTE Attach. As shown in Figure 1, the UE cannot register in the LTE network. Thus, even if the UE is in an LTE network environment, it cannot use the services provided by the LTE network. Summary of the invention

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It is to be understood that the embodiments described herein are intended to illustrate and explain the invention and are not intended to limit the invention.

As shown in FIG. 2, a method for registering a network according to an embodiment of the present invention includes: S21: After determining that the first registration request initiated by the terminal to the network server is rejected, the terminal sends the network to the network. The server initiates a second registration request, where the first registration request carries the default APN parameter; the second registration request does not carry the APN parameter, or the second registration request carries the APN parameter that the terminal successfully registers to the network.

After the terminal initiates the first registration request to the network server, if the network server receives a registration rejection (reject) returned by the first registration request, it determines that the first registration request is rejected.

S22. After receiving the registration accept message returned by the network server for the second registration request, the terminal determines that it has successfully registered to the network.

In the embodiment of the present invention, after determining that the first registration request initiated by the terminal to the network server is rejected, the terminal initiates a second registration request to the network server, where the first registration request carries a default APN parameter; the second registration request does not carry The APN parameter, or the second registration request, carries the APN parameter that the terminal successfully registers to the network from the saved one; after receiving the registration accept message returned by the network server for the second registration request, the terminal determines that it has successfully registered to the network. After the terminal determines that the first registration request for carrying the APN parameter initiated by the network server is rejected, the terminal initiates a second registration request to the network server that does not carry the APN parameter or carries the terminal to successfully save the APN parameter from the successfully registered network to the network. Therefore, the success rate of the terminal registration to the network is improved, and the user can enjoy the service provided by the LTE network in the LTE network environment, thereby improving the user experience.

In implementation, the method further includes:

After receiving the registration accept message returned by the network server, the terminal saves the first information related to the registration of the terminal, where the registration accept message is a registration acceptance returned by the network server for the first registration request and/or the second registration request. Message

The first information includes at least one of the following information: an APN parameter used by the terminal for registration, time information at the time of registration, and ID information used when registering (eg, an international mobile subscriber identifier (International Mobile Subscriber) Identifier, IMSI)), and the information of the Public Land Mobile Network (PLMN) where the registration was made.

Specifically, after receiving the registration accept message returned by the network server for the first registration request and/or the second registration request, the terminal determines that it has successfully registered to the network, and saves the first related to the successful registration of the terminal. information. Further, if the registration accept message is a registration accept message returned by the network server for the first registration request, the first information includes at least one of the following information: an APN parameter carried in the first registration request, and a time of registration Information, ID information used for registration (such as IMSI), and information about the PLMN at the time of registration;

If the registration accept message is a registration accept message returned by the network server for the second registration request, the first information includes at least one of the following information: an APN parameter carried in the registration accept message, time information at the time of registration, The ID information (such as IMSI) used at the time of registration, and the information of the PLMN at the time of registration.

In an implementation, in S21, the terminal initiates, to the network server, a second registration request that carries the APN parameter that the terminal successfully saves from the saved registration to the network, including:

The terminal selects at least one APN parameter from the saved first information related to the successful registration, and initiates the second registration request to the network server, where the second registration request carries the APN parameter selected by the terminal.

In an implementation, in S21, the terminal initiates a second registration request to the network server, and includes the following two preferred implementation manners:

Manner 1: The terminal initiates a second registration request only to the network server.

In this mode, if the second registration request does not carry the APN parameter, the network server, after receiving the second registration request initiated by the terminal, can complete the registration of the terminal in the network, and then complete the registration to the terminal. Returning the registration acceptance message, and carrying the APN parameter sent by the network server to the terminal; if the registration of the terminal in the network cannot be completed, returning the registration rejection message to the terminal.

In this mode, if the second registration request carries the saved APN parameter that is successfully registered to the network, the network server determines whether the APN parameter carried in the second registration request is appropriate after receiving the second registration request. If appropriate, the network server completes the registration acceptance message returned to the terminal after the terminal registers in the network; if not, the network server returns a registration rejection message to the terminal.

In this manner, if the terminal receives the registration accept message returned by the network server after initiating the second registration request to the network server, the terminal determines that it has successfully registered to the network. Manner 2: The terminal initiates at least two second registration requests to the network server.

In this mode, in order to avoid the network server rejecting the second registration request due to a problem in the transmission process (such as data garbled, etc.), the terminal determines that the first second registration request initiated by the terminal to the network server is rejected, and then tries again. The web server initiates a second registration request until either of the second registration request is accepted or the second number of registration requests are rejected.

In this mode, for any second registration request initiated by the terminal, if the network server can complete the registration of the terminal in the network after receiving the second registration request initiated by the terminal, the network server returns to the terminal after completing the registration. The registration accept message; if the network server cannot complete the registration of the terminal in the network, a registration rejection message is returned to the terminal.

In this mode, if any second registration request initiated by the terminal to the network server is accepted, the terminal determines that it has successfully registered to the network.

In this mode, when the terminal initiates at least two second registration requests to the network server, the following two methods are included:

The terminal first initiates a second registration request that does not carry the APN parameter to the network server, and after all the second registration requests that do not carry the APN parameter are rejected, the terminal initiates the set number of mobile terminals to the network server. a second registration request from the saved APN parameter successfully registered to the network; or

The terminal first initiates a second registration request of the set number of times to the network server, and initiates the setting to the network server after all the initiated registration requests are rejected from all the saved APN parameters of the successfully registered APN parameters of the network. The second registration request does not carry the APN parameter.

The set number of times is an empirical value, which may be one time or multiple times. The user can set the specific value according to the actual needs.

In this manner, if the second registration request does not carry the APN parameter, the method further includes: the terminal determining that the second registration request initiated by the terminal is rejected;

The terminal selects at least one APN parameter from the saved first information related to the successful registration, and re-initiates a second registration request to the network server, where the re-initiated second registration request carries the APN parameter selected by the terminal. Specifically, if the second registration request initiated by the terminal that does not carry the APN parameter is rejected, the terminal selects an APN parameter from the saved first information, and re-initiates the carrying of the selected APN to the network server. a second registration request of the parameter; if the second registration request re-initiated is rejected, and then selecting an APN parameter from the remaining first information, and re-initiating the second APN parameter carrying the selected APN parameter to the network server The registration request, and so on, until a second re-initiated second registration request is accepted or each re-initiated second registration request is rejected.

Preferably, the terminal selects at least one APN parameter from the saved first information, including: the terminal determines, from the saved first information, the ID information currently used by the terminal and/or the current PLMN. The information is the same APN parameter, and from the determined APN parameters, at least one APN parameter is selected.

Specifically, the following three implementation manners are implemented: the terminal determines, from the saved first information, an APN parameter that is the same as the ID information currently used by the terminal, and selects at least one APN parameter from the determined APN parameters; or The terminal determines the same APN parameter from the saved first information, and selects at least one APN parameter from the determined APN parameter; or, the terminal saves from the saved In an information, an APN parameter that is the same as the ID information currently used by the terminal and the information of the currently located PLMN is determined, and at least one APN parameter is selected from the determined APN parameters.

Preferably, the terminal selects at least one APN parameter from the determined APN parameters, including: the terminal selects the interval between the registration time information and the current time according to each APN parameter from the determined APN parameters, and sequentially selects the interval. The smallest APN parameter.

Specifically, the terminal first selects the APN parameter with the smallest interval, and re-initiates the second registration request. If the registration fails, the APN parameter with the smallest interval is selected from the remaining APN parameters, and the second registration request is re-initiated, and so on, until the registration is repeated. The second registration request initiated or the second registration request reinitiated each time is rejected.

Of course, in addition to the foregoing preferred selection manner, the terminal may select another APN parameter from the determined APN parameters to re-initiate the second registration request, such as random selection, which is not specific to the embodiment. The selection method is limited. A method for activating the Internet Protocol IP provided by the embodiment of the present invention is described in detail below with reference to two specific embodiments.

Embodiment 1 This embodiment uses an LTE network registration as an example. As shown in FIG. 3, the embodiment includes the following process:

1 : In the LTE network, the terminal initiates a registration request carrying the APN parameter to attempt to register in the LTE network;

If the registration request is accepted (ie, the registration is successful), the terminal saves the currently used APN, and the International Mobile Subscriber Identifier (IMSI) of the terminal and the PLMN where the terminal is currently located no longer perform other operations;

If the registration request is rejected, the terminal performs step 2.

2: The terminal re-initiates the registration request, and the APN parameter is not carried in the registration request; if the network environment supports the network to send the APN, the registration can be successful;

If the network environment does not support the active delivery of APN, it will continue to return to the registration rejection, and the terminal performs step 3.

3: The terminal checks the IMSI and PLMN of the terminal from the information used by the saved LTE network, and compares the current IMSI and PLMN of the terminal, and checks whether other APNs have been successfully registered to the LTE network before, if any, These APN parameters (ie, preferred APN parameters) are then carried in the registration request to attempt to register into the LTE network.

Preferably, the attempt sequence is based on the principle of proximity, that is, using the APN used in the most recent time, and if it fails, then the used APN parameters are carried in the registration request for a longer time.

Embodiment 2: The network of the LTE of the A operator only supports the manner in which the PN registration must carry the APN (ie, the mode mentioned in the background art 2). The LTE network of the operator B also supports the mode of carrying the APN and not carrying the APN when the LTE is registered (that is, the mode 1 and mode 2 mentioned in the background art), that is, if the LTE is registered without the APN, the registration can be successful.

User C is an old customer of A carrier. Because of the business trip, user C replaces the carrier B's card and starts to use carrier B's network. User C uses the A carrier APN to register the LTE network in the LTE network environment of the operator B. After the LTE registration fails, the user C re-attempts to use the APN to register the LTE network of the business B, and the network support of the operator B actively delivers the APN, so the LTE registration is successful.

Based on the same inventive concept, an embodiment of the present invention provides a terminal device. As shown in FIG. 4, the terminal device includes:

The first processing module 41 is configured to initiate a second registration request to the network server after determining that the first registration request initiated by the network server is rejected, where the first registration request carries a default APN parameter; The second registration request does not carry the APN parameter, or the second registration request carries the APN parameter that the terminal successfully registers to the network from the saved one;

The second processing module 42 is configured to receive, by the first processing module 41, the registration accept message returned by the network server for the second registration request, and determine that the terminal device to which the network device belongs has successfully registered to the network.

In the embodiment of the present invention, after determining that the first registration request initiated by the network server is rejected, the first processing module 41 initiates a second registration request to the network server, where the first registration request carries a default APN parameter; The registration request does not carry the APN parameter, or the second registration request carries the APN parameter from the saved successful registration to the network; the second processing module 42 receives the registration returned by the network server for the second registration request at the first processing module 41. After acceptance, it is determined that the terminal device to which it belongs has been successfully registered to the network. After the first processing module 41 determines that the first registration request for carrying the APN parameter initiated by the network server is rejected, the first processing module 41 initiates the APN parameter that does not carry the APN parameter or carries the successfully registered registration to the network. The second registration request improves the success rate of the terminal device to register with the network, so that the user can enjoy the service provided by the LTE network in the LTE network environment, thereby improving the user experience.

In implementation, the terminal device further includes:

The storage module 43 is configured to save, after the first processing module 41 receives the registration accept message returned by the network server, first information related to registration of the terminal device, where the registration accept message is a first registration of the network server a registration acceptance message returned by the request and/or the second registration request; wherein the first information includes at least one of the following information: an APN parameter used for registration of the terminal device, time information at the time of registration, and registration time Identification ID information used (eg IMSI), and the information of the public land mobile network PLMN where the registration is located.

Specifically, if the registration accept message is a registration accept message returned by the network server for the first registration request, the first information includes at least one of the following information: an APN parameter carried in the first registration request, and a registration time Time information, ID information used for registration (such as IMSI), and information about the PLMN at the time of registration;

In an implementation, the first processing module 41 initiates a second registration request to the network server, including the following two preferred implementations:

In a first manner, the first processing module 41 initiates a second registration request to the network server only once.

In this mode, if the second registration request does not carry the APN parameter, the network server, after receiving the second registration request initiated by the first processing module 41, can complete the registration of the terminal device in the network, After the registration is completed, the registration accept message is returned to the first processing module 41, and the APN parameter sent by the network server to the terminal device is carried. If the terminal device is not registered in the network, the first processing module 41 is sent to the first processing module 41. Returns a registration rejection message.

In this manner, if the second registration request carries the saved APN parameter that is successfully registered to the network, the network server determines whether the APN parameter carried in the second registration request is appropriate after receiving the second registration request. If appropriate, the network server completes the registration accept message returned to the first processing module 41 after the terminal device registers with the network; if not, the network server returns a registration reject message to the first processing module 41.

In this manner, if the first registration module 41 receives the registration accept message returned by the network server after the second registration request initiated by the network server, the second processing module 42 determines that the terminal device to which it belongs has been successfully registered in the network.

Manner 2: The first processing module 41 initiates at least two second registration requests to the network server. In this mode, in order to avoid problems caused by the transmission process (such as data garbled, etc.) The network server rejects the second registration request, and the first processing module 41 determines that the first second registration request initiated by the network server is rejected, and then attempts to initiate a second registration request to the network server until any second registration request The second registration request accepted or set the number of times is rejected.

In this manner, for any second registration request initiated by the first processing module 41, if the network server receives the second registration request initiated by the first processing module 41, the network device can complete the registration of the terminal device in the network. And returning the registration accept message to the first processing module 41 after the registration is completed, and carrying the APN parameter sent by the network server to the terminal device; if the registration of the terminal device in the network cannot be completed, the first Processing module 41 returns a registration reject message.

In this manner, when the first processing module 41 initiates at least two second registration requests to the network server, the following two methods are included:

The first processing module 41 first initiates a second registration request that does not carry the APN parameter to the network server, and initiates the setting to the network server after all the second registration requests that do not carry the APN parameter are rejected. The number of times carries a second registration request from the saved APN parameter that was successfully registered to the network; or

The first processing module 41 first initiates a second registration request of the set number of times to the network server, and after all the second registration requests that carry the APN parameters from the saved successfully registered to the network are rejected, and then go to the network server. A second registration request that does not carry an APN parameter is initiated for a set number of times.

In this manner, if the second registration request does not carry the APN parameter, preferably, the second processing module 42 is further configured to:

Determining that the second registration request initiated by the first processing module 41 is rejected; from the first information saved by the storage module 43, selecting at least one APN parameter, and re-initiating a second registration request to the network server, where The second registration request that is re-initiated carries the APN parameter selected by the second processing module 42.

Specifically, if the second registration request initiated by the first processing module 41 does not carry the APN parameter is rejected, the second processing module 42 selects one of the first information that has been saved by the storage module 43. The APN parameters are re-initiated, and the second registration request carrying the selected APN parameter is re-initiated to the network server; if the second re-initiated registration request is rejected, the second processing module 42 re-enters the remaining first information. Selecting an APN parameter, and re-initiating a second registration request carrying the selected APN parameter to the network server, and so on, until a second re-initiated second registration request is accepted or a second registration request is re-initiated each time Both were rejected.

Preferably, the second processing module 42 selects at least one APN parameter from the first information saved by the storage module 43, including:

From the first information that has been saved by the storage module 43, the APN parameter that is the same as the ID information currently used by the terminal device and/or the information of the currently located PLMN is determined, and at least one of the determined APN parameters is selected. APN parameters.

Specifically, the following three implementation manners are included: the second processing module 42 determines, from the first information that has been saved by the storage module 43, the APN parameter that is the same as the ID information currently used by the terminal device, and from the determined APN parameters, Selecting at least one APN parameter; or, the second processing module 42 determines, from the first information that has been saved by the storage module 43, the APN parameter that is the same as the information of the PLMN that the terminal device is currently located, and from the determined APN parameter, Selecting at least one APN parameter; or, the second processing module 42 determines, from the first information that has been saved by the storage module 43, the APN parameter that is the same as the ID information currently used by the terminal device and the information of the currently located PLMN, and Among the determined APN parameters, at least one APN parameter is selected.

Preferably, the second processing module 42 selects at least one APN parameter from the determined APN parameters, including:

From the determined APN parameters, the interval between the registration time information and the current time is selected according to each APN parameter, and the APN parameters with the smallest interval are sequentially selected.

Specifically, the second processing module 42 first selects the APN parameter with the smallest interval, and re-initiates the second registration request. If the registration fails, the APN parameter with the smallest interval is selected from the remaining APN parameters, and the second registration request is re-initiated. By analogy, the second registration request is accepted until the second registration request is reinitiated or rejected.

Of course, in addition to the above preferred selection methods, the second processing module 42 can also use other The method selects an APN parameter from the determined APN parameter to re-initiate the second registration request, such as a random selection. The embodiment of the present invention does not limit the specific selection manner.

Based on the same inventive concept, an embodiment of the present invention provides a terminal device. As shown in FIG. 5, the terminal device includes:

The transceiver 51 is configured to initiate a second registration request to the network server after determining that the first registration request initiated by the network server is rejected, where the first registration request carries a default APN parameter; The APN parameter is not carried, or the second registration request carries the APN parameter from the saved successful registration to the network;

The processor 52 is configured to determine, after the transceiver 51 receives the registration accept message returned by the network server for the second registration request, that the terminal device to which the network device belongs has successfully registered to the network.

The transceiver 51 and the processor 52 are connected by a bus.

In the embodiment of the present invention, the transceiver 51 initiates a second registration request to the network server after determining that the first registration request initiated by the network server is rejected, wherein the first registration request carries a default APN parameter; the second registration request The APN parameter is not carried in the second registration request, or the second registration request carries the APN parameter from the saved successful registration to the network; after receiving the registration accept message returned by the network server for the second registration request, the processor 52 determines itself. The associated terminal device has been successfully registered to the network. After the transceiver 51 determines that the first registration request for carrying the APN parameter initiated by the network server is rejected, the transceiver 51 initiates the non-carrier APN parameter or carries the selected information from the saved first information related to the successful registration. The second registration request of the APN parameter improves the success rate of the terminal device to register with the network, so that the user can enjoy the service provided by the LTE network in the LTE network environment, thereby improving the user experience.

In implementation, the terminal device further includes:

The memory 53 is configured to save, after the transceiver 51 receives the registration accept message returned by the network server, first information related to registration of the terminal device, where the registration accept message is a network server for the first registration request and/or Or a registration acceptance message returned by the second registration request;

The first information includes at least one of the following information: an APN parameter used for registration of the terminal device, time information at the time of registration, and identifier ID information used when registering, And the information of the public land mobile network PLMN where the registration is located.

In an implementation, the transceiver 51 initiates a second registration request to the network server, including the following two preferred implementations:

Method 1, the transceiver 51 initiates a second registration request to the network server only once.

In this mode, if the APN parameter is not carried in the second registration request, after the network server receives the second registration request initiated by the transceiver 51, if the registration of the terminal device in the network can be completed, the registration is completed. The backward transceiver 51 returns a registration accept message and carries the APN parameter sent by the network server to the terminal device; if the terminal device is not registered in the network, the registration reject message is returned to the transceiver 51.

In this manner, if the second registration request carries the saved APN parameter that is successfully registered to the network, the network server determines whether the APN parameter carried in the second registration request is appropriate after receiving the second registration request. If appropriate, the network server completes the registration accept message returned to the transceiver 51 after the terminal device registers with the network; if not, the network server returns a registration reject message to the transceiver 51.

In this mode, if the transceiver 51 returns a registration accept message returned by the network server after the second registration request initiated by the network server, the processor 52 determines that the terminal device to which it belongs has successfully registered in the network.

Mode 2: The transceiver 51 initiates at least two second registration requests to the network server.

In this mode, in order to avoid problems caused by the transmission process (such as data garbled, etc.) The network server rejects the second registration request, and the transceiver 51 determines that the first second registration request initiated by the network server is rejected, and then attempts to initiate a second registration request to the network server until any second registration request is accepted. Or the second registration request of the set number of times is rejected.

In this manner, for any second registration request initiated by the transceiver 51, if the network server can complete the registration of the terminal device in the network after receiving the second registration request initiated by the transceiver 51, the completion is completed. After registration, the registration accept message is returned to the transceiver 51, and carries the APN parameter sent by the network server to the terminal device; if the terminal device is not registered in the network, the registration rejection message is returned to the transceiver 51.

In this manner, when the transceiver 51 initiates at least two second registration requests to the network server, the following two methods are included:

The transceiver 51 first initiates a second registration request that does not carry the APN parameter to the network server, and after all the second registration requests that do not carry the APN parameter are rejected, the network server initiates the set number of times. Carrying a second registration request from the saved APN parameters successfully registered to the network; or

The transceiver 51 first initiates a second registration request of the set number of times to the network server, and initiates a second registration request that carries the APN parameter from the saved successful registration to the network, and then initiates the setting to the network server. A fixed number of second registration requests that do not carry APN parameters.

In this manner, if the second registration request does not carry the APN parameter, preferably, the processor 52 is further configured to:

Determining that the second registration request initiated by the transceiver 51 is rejected; from the first information saved in the memory 53, selecting at least one APN parameter, and re-initiating a second registration request to the network server, where The second registration request carries the APN parameter selected by the processor 52.

Specifically, if the second registration request initiated by the transceiver 51 that does not carry the APN parameter is rejected, the processor 52 selects an APN parameter from the first information saved in the memory 53. And re-initiating a second registration request carrying the selected APN parameter to the network server; if the second re-initiated registration request is rejected, the processor 52 selects an APN parameter from the remaining first information, and A second registration request carrying the selected APN parameter is re-initiated to the network server, and so on, until a second re-initiated second registration request is accepted or a second re-initiated second registration request is rejected.

Preferably, the processor 52 selects at least one APN parameter from the first information saved by the memory 53, including:

From the first information that has been saved in the memory 53, the APN parameter that is the same as the ID information currently used by the terminal device and/or the information of the currently located PLMN is determined, and at least one APN is selected from the determined APN parameters. parameter.

Specifically, the following three implementation manners are included: The processor 52 determines, from the first information that has been saved in the memory 53, the same APN parameter that is currently used by the terminal device, and selects at least one of the determined APN parameters. The APN parameter; or, the processor 52 determines the APN parameter that is the same as the information of the PLMN where the terminal device is currently located, and selects at least one APN parameter from the determined APN parameters. Alternatively, the processor 52 determines, from the first information that has been saved in the memory 53, the APN parameter that is the same as the ID information currently used by the terminal device and the information of the currently located PLMN, and selects at least from the determined APN parameters. An APN parameter.

Preferably, the processor 52 selects at least one APN parameter from the determined APN parameters, including:

Specifically, the processor 52 first selects the APN parameter with the smallest interval, and re-initiates the second registration request. If the registration fails, the APN parameter with the smallest interval is selected from the remaining APN parameters, and the second registration request is re-initiated, and so on. The second registration request until either re-initiation of the re-initiation is accepted or the second registration request is re-initiated each time.

Of course, in addition to the preferred selection described above, the processor 52 can also use other methods. Among the determined APN parameters, an APN parameter is selected to re-initiate the second registration request, such as a random selection. The embodiment of the present invention does not limit the specific selection manner.
