Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.

In the prior art, when a mobile terminal initiates a 4G network camp-on to an access network, if a user sets an APN incorrectly, for example, assuming that the mobile terminal initiates a 4G network camp-on to an a network operator, but the user sets an APN to a B network operator, the a network operator may reject the 4G network camp-on of the mobile terminal, and sends a rejection message to the mobile terminal to notify the mobile terminal. And after the mobile terminal is refused to reside in the 4G network, the APN is not verified when the 2G network and the 3G network reside in the network, so that the mobile terminal can perform network residence in the 2G network or the 3G network so as to further acquire the service. However, in the above scenario, the user does not enjoy the high-speed service of 4G, thereby degrading the user's experience.

Based on the above problem, the embodiment of the present application provides a network residence method.

Referring to fig. 1 and fig. 2, a network residing method provided in an embodiment of the present application is described, where fig. 1 is an application scenario provided in an embodiment of the present application, and referring to fig. 1, the application scenario includes a mobile terminal 100, a first network 201, and a second network 202.

A mobile terminal can also be called a terminal device, User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. The Mobile terminal may be a Station (ST) in a WLAN, and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a vehicle networking terminal, a computer, a laptop, a handheld communication device, a handheld computing device, a satellite radio, a Wireless modem card, a Set Top Box (STB), a Customer Premises Equipment (CPE), and/or other devices for communicating over a Wireless system, as well as a next generation communication system, e.g., a Mobile terminal in a 5G Network or a future evolved Public Land Mobile Network (Public Land Mobile Network, PLMN) mobile terminals in the network, etc. The mobile terminal may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user.

The first network 201 and the second network 202 may be networks in a PLMN, and illustratively, the first network 201 may be a 4G network and the second network 202 may be a 2G or 3G network.

It should be noted that the above example only exemplarily shows an application scenario in which the first network 201 is a 4G network and the second network 202 is a 2G or 3G network, and does not constitute a limitation to the embodiment of the present application, and in some embodiments, the first network 201 may also be another network higher than 4G, and the second network 202 may also be another network lower than 4G, for example, the first network 201 may also be a 5G or higher network, and the second network 202 may also be a 2.5G network.

Fig. 2 is a schematic flowchart of an embodiment of a network hosting method provided in the present application, including:

in step 101, the mobile terminal 100 searches for the first network 201 and receives the first system information broadcast by the first network 201.

Specifically, when the mobile terminal 100 is powered on, the mobile terminal 100 may search for a network available nearby according to the turned-on network access capabilities (e.g., 2G capability, 3G capability, and 4G capability). In particular implementations, the mobile terminal 100 may search for a network with the highest network access capability, e.g., a 4G network. For example, if the mobile terminal 100 turns on 2G, 3G and 4G capabilities, it is indicated that the mobile terminal 100 supports access to 2G, 3G and 4G networks. Next, since the bandwidth and data transmission efficiency of the 4G network are higher than those of the 2G and 3G networks, and thus the 4G network capability is higher than those of the 2G and 3G networks, the mobile terminal 100 may first search for the 4G network. When the mobile terminal 100 finds the first network 201 (e.g., 4G network) by searching, it may receive the first system information broadcast by the first network 201. In a specific implementation, the mobile terminal 100 may receive the first system information broadcast by the first network 201 through a common channel. The first system information may include PLMN information, which may be used to characterize a PLMN to which the first network 201 belongs. It is to be understood that the first network 201 may provide access network capabilities, e.g., 4G capabilities, corresponding to the first network 201.

In step 102, the mobile terminal 100 initiates a first network camping request to the first network 201.

Specifically, after receiving the first system message broadcast by the first network 201, the mobile terminal 100 may further initiate a first network camping request to the first network 201. The first network camping request is used for the mobile terminal 100 to request the first network 201 to camp on, so that the mobile terminal 100 can register on the first network 201, thereby enabling the mobile terminal 100 to use a data service (e.g., a 4G service) provided by the first network 201. The first camp-on request may include APN (e.g., name of access network operator) information. It is understood that the first network 201 may correspond to an APN, that is, the first network 201 may belong to an access network operator (for example, any operator in china mobile, china unicom or chinese telecom). The APN may correspond to SIM card information in the mobile terminal 100. For example, if the subscriber is a SIM card for china mobile, the APN information of the carrier for china mobile is carried in the first network camping request initiated by the mobile terminal 100.

Step 103, the first network 201 receives the first network camping request sent by the mobile terminal 100, and sends a feedback message to the mobile terminal 100 based on the first network camping request.

Specifically, after the first network 201 receives the first network camping request sent by the mobile terminal 100, since the first network 201 is a 4G network, according to a protocol requirement (specifically, refer to protocol 3GPP TS24.301, which is not described herein again), the APN information in the first network camping request needs to be verified. For example, the first network 201 may read APN information in the first network camping request.

If the content in the APN information is consistent with the APN corresponding to the first network 201, for example, it is assumed that the APN information included in the first network camping request is APN equal to an a operator, and if the first network 201 is operated by the a operator, it indicates that the content in the APN information is consistent with the APN corresponding to the first network 201, and the first network 201 may accept the first network camping request of the mobile terminal 100, that is, the first network 201 may register the mobile terminal 100 on its own device and may provide a 4G service to the mobile terminal 100. Further, the first network 201 may also send an acknowledgement message to the mobile terminal 100, where the acknowledgement message is used to notify the mobile terminal 100 that the network camping is successful and the 4G service may be used.

If the content in the APN information is not consistent with the APN corresponding to the first network 201, for example, if the user performs an error operation in the mobile terminal 100, the APN information is changed from APN of the a operator to APN of the B operator, the APN information included in the first network camping request is APN of the B operator, if the first network 201 is operated by the a operator, it indicates that the content in the APN information is not consistent with the APN corresponding to the first network 201, and the first network 201 may reject the first network camping request of the mobile terminal 100, that is, the first network 201 may reject the registration of the mobile terminal 100 on its own device, so the mobile terminal 100 cannot enjoy the 4G service provided by the first network 201. Further, the first network 201 may also send a rejection message to the mobile terminal 100, for example, the rejection message may be an ATTACH REJ message and a PDN REJ message, and the ATTACH REJ message and the PDN REJ message may specifically refer to the protocol 3GPP TS24.301, which is not described herein again.

In step 104, the mobile terminal 100 receives the feedback message sent by the first network 201, and closes the 4G capability based on the feedback message.

In particular, the feedback message may comprise an acknowledgement message or a rejection message.

If the mobile terminal 100 receives the acknowledgement message sent by the first network 201, the mobile terminal 100 may reside on a 4G network covered by the first network 201.

If the mobile terminal 100 receives the rejection message sent by the first network 201, the mobile terminal 100 may further determine the content in the rejection message. For example, the mobile terminal 100 may determine whether a back-off timer (back-off timer) is included in the reject message. The back off timer is used to characterize a timer that allows bearer establishment, that is, a bearer corresponding to the APN is not allowed to be established in a time period of the timer, and specific details of the back off timer may refer to protocol 3GPP TS24.301, which is not described herein again. Illustratively, the back off timer may be carried in the PDN REJ message.

If the mobile terminal 100 determines that the PDN REJ message does not carry a back off Timer, according to a protocol (e.g., 3GPP protocol TS24.301), the mobile terminal 100 may turn off the 4G capability and start a Timer Disable LTE Timer, where the Timer Disable LTE Timer is used to represent a Timer for reactivating the 4G capability of the mobile terminal 100, that is, in a time period of the Timer Disable LTE Timer, the mobile terminal 100 turns off the 4G capability, and after the Timer Disable LTE Timer expires, the mobile terminal 100 may restart the 4G camping request.

In step 105, the mobile terminal 100 searches for the second network 202 and receives the second system information broadcast by the second network 202.

Specifically, after the mobile terminal 100 turns off the 4G capability, the mobile terminal 100 may search for the nearby second network 202 based on the 2G or 3G capability. When the second network 202 is searched, the second system message sent by the second network 202 can be received. In particular implementations, the mobile terminal 100 may receive the second system information broadcast by the second network 202 through a common channel. The second system information may include PLMN information, which may be used to characterize a PLMN to which the second network 202 belongs. It is to be understood that the second network 202 may provide access network capabilities corresponding to the second network 201, e.g. 2G or 3G capabilities.

In step 106, the mobile terminal 100 sends a second network camping request to the second network 202.

Specifically, after receiving the second system message broadcast by the second network 202, the mobile terminal 100 may send a second network camping request to the second network 202, so as to register the mobile terminal 100 on the 2G or 3G network covered by the second network 202, so that the mobile terminal 100 can use the 2G or 3G network. The second camping request may also include the above-mentioned wrong APN information (e.g., APN ═ B carrier).

Step 107, the second network 202 receives the second network camping request sent by the mobile terminal 100, and sends a confirmation message to the mobile terminal 100.

Specifically, after the second network 202 receives the second network-camping request sent by the mobile terminal 100, because the second network 202 is a 2G or 3G network, according to a protocol requirement (e.g., 3GPP), the second network 202 may not verify APN information in the second network-camping request, and the second network 202 may directly accept the network-camping request of the mobile terminal 100 and send a confirmation message to the mobile terminal 100. Wherein the acknowledgement message may include the correct APN information. The correct APN information may be identity information of an operator corresponding to the second network 202 (e.g., APN ═ a operator).

Step 108, the mobile terminal 100 receives the acknowledgement message sent by the second network 202, and acquires APN information in the acknowledgement message.

Specifically, after the mobile terminal 100 receives the acknowledgement message sent by the second network 202, the APN information in the acknowledgement message may be read. In this case, the mobile terminal 100 may use the APN information in the acknowledgement message as the latest APN information, and then may replace the APN information set by the user in the mobile terminal 100 with the APN information in the acknowledgement message, for example, may replace an APN that is set by the user in error with an APN of a B carrier.

Step 109, the mobile terminal 100 compares the PLMN information in the first system information with the PLMN information in the second system information, and sends a third network camping request to the first network 201 based on the comparison result.

Specifically, after receiving the confirmation message sent by the second network 202, the mobile terminal 100 may further compare the PLMN information in the first system information with the PLMN information in the second system information. Usually, the mobile terminal 100 will initiate the network camping request to the second network 202 immediately after receiving the rejection message from the first network 201, so that the mobile terminal 100 will not move a large distance, that is, the PLMN where the first network 201 is located and the PLMN where the second network 202 is located are the same PLMN. At this time, if the mobile terminal 100 determines, by comparing, that the PLMN in the first system information is the same as the PLMN in the second system information, the mobile terminal 100 may restart the 4G capability and send a third network camping request to the first network 201. Wherein the third camp-on request may include the latest APN information (e.g., APN ═ a carrier).

If the mobile terminal 100 determines, by comparing, that the PLMN in the first system information is different from the PLMN in the second system information, the mobile terminal 100 may wait for the expiration of the Timer Disable LTE Timer, and after the expiration of the Timer Disable LTE Timer, the mobile terminal 100 may start the 4G capability and may send a third network camping request to the first network 201.

In step 110, the first network 201 receives the third network camping request sent by the mobile terminal 100, and receives the third network camping request of the mobile terminal 100.

Specifically, after receiving the third network camping request sent by the mobile terminal 100, the first network 201 verifies the APN information in the third network camping request again. Since the first network 201 is operated by the a operator, and the third network camping request carries the correct APN information (for example, APN ═ a operator), the third network camping request of the mobile terminal 100 at this time can pass, that is, the first network 201 can accept the third network camping request of the mobile terminal 100, and the mobile terminal 100 can successfully camp on the 4G network covered by the first network 201, so that the mobile terminal 100 can use the 4G service, and the user experience is improved.

In step 111, the first network 201 sends an acknowledgement message to the mobile terminal 100.

Specifically, the first network 201 may further send a confirmation message to the mobile terminal 100 after accepting the third network camping request of the mobile terminal 100. The confirmation message is used to inform the mobile terminal 100 that its third network camping request has passed, that the mobile terminal 100 has completed the network camping, and that the use of the 4G service can be started.

In the embodiment of the application, after the mobile terminal receives the message of rejecting access of the 4G network, correct APN information can be obtained by accessing the 2G or 3G network, and a network residing request can be initiated to the 4G network again according to the correct APN information, so that the situation that the network residing request is initiated to the 4G network after the timer is overtime can be avoided, and further the 4G network residing request can be initiated more quickly, 4G services can be used more quickly, and user experience is improved.
