Network attachment method, device and mobile terminal

[Technical Field]

The present invention relates to the field of mobile communications technologies, and in particular, to a network attaching method, apparatus, and mobile terminal.

【Background technique】

When the mobile terminal is powered on, restarted, or switched from the flight mode to the normal working mode, the mobile terminal needs to search for a connectable target network for network attachment. After the network is attached, the mobile terminal can communicate normally.

At present, the process of the mobile terminal attaching the network is as shown in FIG. 1 : the mobile terminal sends a network attach request to the target network; the network attach request carries a PTI (Procedure Transaction ID) identifier, and the PTI identifier is used for attaching to the network. The process identifies a transaction in the process to avoid network attachment conflicts. The PTI identifier carried in the network attach request is PTI1. After receiving the attach request message, the target network performs mutual authentication, NAS (Non-access Stratum) security negotiation, and ESM (EPS Session Management) information transmission with the mobile terminal, and then the target network. An attach response is sent to the mobile terminal; the attach response carries a default bearer activation command. The mobile terminal activates the default bearer according to the default bearer activation command, and then sends an attach complete message to the target network. After the network attachment process is completed, the mobile terminal can perform normal data transmission and communication.

As shown in FIG. 2, if the mobile terminal does not receive the attach response returned by the target network within the set waiting time during the network attachment process, the mobile terminal resends the network attach request, and the network attach request sent this time. The carried PTI identifier is PTI2. At this time, if the target network happens to send the attach response of the network attach request corresponding to PTI1 to the mobile terminal. The mobile terminal ignores the attach response because the PTI does not match, and the target network also ignores the network attach request resent by the mobile terminal due to the PTI mismatch, and finally causes the target network to cull the bearer and the mobile terminal is disconnected from the network.

【detailed description】

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of the embodiments of the invention, which are generally described and illustrated in the figures herein, may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the invention in the claims All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

At present, in the process of network attachment, such as a mobile phone, the mobile terminal may not be able to connect to the network due to the mismatch of the transaction identifier, thereby reducing the communication experience of the user using the mobile network. Based on this, an embodiment of the present invention provides a network attachment method, device, and mobile terminal, so as to reduce the off-network of the mobile terminal caused by the conflict of the transaction identifier, and improve the communication experience of the user using the mobile network.

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

FIG. 3 is a flowchart of a method for attaching a network according to an embodiment of the present invention. The method may be applied to a mobile terminal, such as a mobile phone, a palmtop computer, a sales terminal, an in-vehicle computer, a smart wearable device, or the like. As shown in FIG. 3, the method includes the following steps:

Step S302: If the mobile terminal needs to resend the network attach request, continue to temporarily store the first attachment information corresponding to the sent network attach request. The first attachment information includes at least a first transaction identifier.

When the mobile terminal needs to perform network attachment, for example, when the mobile terminal is powered on, restarted, or switched from the flight mode to the normal working mode, it is necessary to search for a connectable target network for network attachment. After the network attachment is completed, the mobile terminal can use the services provided by the mobile network. At present, the mobile network mainly adopts an LTE (Long Term Evolution) network, and a process in which a mobile terminal performs network attachment, which is also called network registration.

The mobile terminal first sends a network attach request to the target network. A target network can be understood as a radio access network, including a radio network controller and a cell base station. The mobile terminal sends a network attach request to the cell base station. To avoid the network attachment conflict, the network attach request carries a transaction identifier (hereinafter referred to as a first transaction identifier) for identifying a transaction, such as a PTI identifier, in the network attachment process. After receiving the network attach request, the target network performs mutual authentication, NAS security negotiation, and ESM information transmission with the mobile terminal. In the above process, the information exchange between the mobile terminal and the target network carries the first transaction identifier.

In the above network attachment process, the mobile terminal temporarily stores all the information exchanged with the target network, including the first transaction identifier, which is referred to as the first attachment information. The first attachment information may be stored in a designated area in the memory. After completing the above process, the mobile terminal waits for an attachment response returned by the target network. If the duration of the mobile terminal waiting for the attach response exceeds the first set duration, it is determined that the network attach request is currently required to be retransmitted.

In the prior art, if the mobile terminal sends a new network attachment request, the first attachment information corresponding to the last network attachment request to be sent will be lost due to the coverage, and therefore, the first network attachment corresponding to the first attachment is returned. When the information is attached, the mobile terminal cannot find the first attachment information, and an attachment process conflict occurs between the mobile terminal and the target network.

In the embodiment of the present invention, if the mobile terminal currently needs to resend the network attach request, the first attachment information corresponding to the sent network attach request will be temporarily stored.

Step S304, sending a new network attachment request, and temporarily storing the second attachment information corresponding to the new network attachment request. The second attachment information includes a second transaction identifier.

After the new network attachment request is sent, the mobile terminal determines the second storage address of the second attachment information in the memory according to the first storage address of the first attachment information in the memory; and saves the second attachment information to the second storage address. . For example, the second attachment information may be temporarily stored after the first attachment information. It should be noted that the specified area of the memory may temporarily store more than two pieces of attachment information, and the attachment information is stored in the time sequence of sending the network attachment request, and each piece of attachment information corresponds to a network attachment process.

Step S306, when receiving the attach response, compare the third transaction identifier carried by the attach response with the first transaction identifier and the second transaction identifier.

Step S308: Activate the default bearer carried by the attach response according to the comparison result, and send an attach complete message carrying the third transaction identifier to complete the network attach procedure.

When the attach response is received, the third transaction identifier carried by the attach response is extracted, and the third transaction identifier is compared with the first transaction identifier and the second transaction identifier. If the third transaction identifier is consistent with the second transaction identifier, the activation operation of the default bearer is performed according to the second attachment information.

If the third transaction identifier is consistent with the first transaction identifier, the activation operation of the default bearer is performed according to the first attachment information. After the default bearer is activated, an attach complete message carrying the third transaction identifier is sent to complete the network attach process.

The network attaching method, when the mobile terminal needs to resend the network attach request, continues to temporarily store the first attached information corresponding to the sent network attach request, and temporarily stores the second attached information corresponding to the new network attach request. The first attachment information includes a first transaction identifier, and the second attachment information includes a second transaction identifier. When the attachment response returned by the target network is received, the third transaction identifier carried by the attachment response is compared with the first transaction identifier and the second transaction identifier, and the default bearer carried by the attachment response is activated according to the comparison result, and the network attachment process is completed. Therefore, the phenomenon that the mobile terminal is disconnected due to the conflict of the transaction identifier can be reduced, and the communication experience of the user using the mobile network is improved.

For a more convenient understanding, the network attachment method provided by the embodiment of the present invention is illustrated by a specific application example. As shown in FIG. 4, the method includes the following steps:

Step S402: If the mobile terminal needs to resend the network attach request, continue to temporarily store the first attached information corresponding to the first network attach request that has been sent. The first attachment information includes a first transaction identifier.

For example, after the mobile terminal is powered on, it searches for a connectable network. If several connectable networks are found, one network can be selected as the target network. After determining the target network, the mobile terminal initiates a first network attach request to the target network. The first network attach request carries the first transaction identifier - PTI1. The mobile terminal performs a first network attach process with the target network.

The mobile terminal temporarily stores the first attachment information corresponding to the first network attachment request, and the first attachment information includes PTI1.

In the first network attach process, the mobile terminal does not receive the attach response returned by the target network within the first set duration, and therefore, the mobile terminal determines that the network attach request needs to be retransmitted.

Step S404, sending a second network attachment request, and temporarily storing the second attachment information corresponding to the second network attachment request. The second attachment information includes a second transaction identifier.

After the mobile terminal sends the second network attachment request, the second attachment information is temporarily stored in the first attachment information, and the second attachment information includes the second transaction identifier, PTI2.

Step S406: When receiving the attach response, extract the third transaction identifier carried by the attach response.

Step S408, comparing whether the third transaction identifier is consistent with the second transaction identifier; if yes, performing step S410 and step S416; if not, executing step S412.

Step S410, performing an activation operation of the default bearer according to the second attachment information.

Step S412, comparing whether the third transaction identifier is consistent with the first transaction identifier; if yes, executing step S414; if not, executing step S418, waiting for a new attachment response.

Step S414, performing an activation operation of the default bearer according to the first attachment information.

According to the time of sending the network attach request, the third transaction identifier is first compared with the second transaction identifier corresponding to the last network attachment request sent last time. If the third transaction identifier is consistent with the second transaction identifier, the activation operation of the default bearer is performed according to the second attachment information, and the third transaction identifier does not need to be compared with the first transaction identifier. If the third transaction identifier is inconsistent with the second transaction identifier, the third transaction identifier is compared with the first transaction identifier corresponding to the last network attachment request sent last time. If the third transaction identifier is consistent with the first transaction identifier, the activation operation of the default bearer is performed according to the first attachment information.

Optionally, if the third transaction identifier is consistent with the first transaction identifier, the second attachment information may be deleted at the same time as or after the activation operation of the default bearer according to the first attachment information, to save the memory space of the mobile terminal.

Step S416, sending an attach complete message carrying the third transaction identifier to complete the network attach process.

Considering that the mobile terminal does not receive the attachment response of the target network, the network attachment request may be sent multiple times in a period of time. The specified area of the memory temporarily stores multiple pieces of attached information, which occupies a large amount of memory space, which may affect the mobile terminal. Operating efficiency. In order to save the memory space, when the second network attach request is sent in step S404, the temporary storage timer may be started, and the temporary storage timer is used to record the continuation temporary storage duration of the first attached information. If the duration of the temporary timer exceeds the second set duration, the first attachment information is deleted. The second set duration can be set according to an empirical value. For example, the second set duration can be set to 2s.

It should be noted that the temporary storage timer may also be started when the first network attachment request is sent, that is, started at the initial time when the first attachment information is temporarily stored, and used to record the temporary storage duration of the first attachment information. If the temporary storage duration of the first attachment information exceeds the set value, the first attachment information is deleted.

In the above network attachment method, if the third transaction identifier of the attachment response received by the mobile terminal is inconsistent with the second transaction identifier of the last time the network attachment request is sent, the third transaction identifier and the last network attachment request may be sent. The first transaction identifier is compared. If the third transaction identifier is consistent with the first transaction identifier, the activation operation of the default bearer may be performed according to the first attachment information, and the network attachment process is completed. Therefore, the phenomenon that the mobile terminal is disconnected due to the conflict of the transaction identifier can be reduced, and the communication experience of the user using the mobile network is improved.

FIG. 5 is a flowchart of interaction between a mobile terminal and a target network in a process of attaching a network according to an embodiment of the present invention. As shown in FIG. 5, the network attachment process of the mobile terminal includes the following steps:

(3) NAS security negotiation and ESM information transmission between the target network and the mobile terminal, and the agreement on the communication security protocol and data format followed by the communication process of the two parties is stipulated. In the above process, the mobile terminal temporarily stores all the information that interacts with the target network in the network attachment process, which is called the first attachment information.

(4) The target network allocates a temporary identifier and an IP address to the mobile terminal, creates communication context information, and generates a default bearer, and sends an attach response including the default bearer to the mobile terminal. During this time, the mobile terminal will wait for the target network to return an attach response, and if within the specified first set time period, the mobile terminal does not receive the attach response returned by the target network. The mobile terminal will resend the network attach request, and the new network attach request carries the transaction identifier PTI2. The mobile terminal temporarily stores the second attachment information corresponding to the new network attachment request.

(5) After the mobile terminal resends the network attach request, if the target network returns an attach response to the mobile terminal, the transaction identifier carried by the attach response is PTI1. The mobile terminal receives the attach response. After the comparison, it is determined that the transaction identifier PTI1 of the attach response is inconsistent with the transaction identifier PTI2 of the new network attachment request, and is consistent with the transaction identifier PTI1 of the network attachment request sent last time.

(6) The mobile terminal continues to perform the network attach process corresponding to the transaction identifier PTI1 according to the first attachment information, extracts the default bearer from the attach response, parses the IP address and other information, activates the default bearer, and sends the transaction identifier PTI1 to the target network. The attach completion message completes the network attach process.
