[0002] Currently, when a terminal is in a restricted state and needs to obtain an emergency service, it can camp on a cell that supports the emergency service, and then initiate an emergency registration through this cell.

[0047] Step 101: The terminal obtains at least one network identifier list and first indication information provided by the first cell.

[0048] In the embodiments of this application, the above terminal is a Narrowband Internet of Things (NB-IoT) terminal or an enhanced Machine Type Communication (eMTC) terminal. This terminal supports Voice Services, can select or reselect an acceptable cell, and can be in a state of camping on any cell. This terminal can support emergency services.

[0050] In some embodiments of the present application, the terminal is in a Limited Service State.

[0051] In the embodiments of the present application, the above-mentioned first cell supports connection to at least one first core network.

[0052] It can be understood that the first cell is a cell applying RAN sharing technology.

The embodiments of the present application do not limit this here, and those skilled in the art can set it according to usage requirements.

[0054] Among them, each first core network in the at least one first core network may be different.

[0055] In some embodiments of the present application, the terminal may receive a first message, which carries at least one network identifier list and first indication information. The first message may include at least one of the following: System Information Block (SIB) 1, Bandwidth-Reduced System Information Block 1 (SIB1-BR), System Information Block Type 1-Narrow Band (SIB1-NB), etc.

The second message may include at least one of the following: SIB19, SystemInformationBlockType31, SystemInformationBlockType31-NB.

[0057] In the embodiments of the present application, each network identifier list in the at least one network identifier list is used to indicate at least one first network, and the first network is used to provide a connection to a first core network. The first indication information is used to indicate whether each first network supports providing emergency services.

[0058] It can be understood that the at least one first network is the network indicated / provided by the first cell.

[0059] In some embodiments of the present application, for each network identifier list in the at least one network identifier list, the first network indicated by a network identifier list is used to provide a connection to a first core network, and the first networks indicated by different network identifier lists may overlap.

[0060] Exemplarily, assume that the at least one first core network includes EPC and 5GC, and the at least one network identifier list includes network identifier list 1 and network identifier list 2. Network identifier list 1 indicates network 1 and network 2, and network identifier list 2 indicates network 2 and network 4. Then, network 1 and network 2 indicated by network identifier list 1 can provide a connection to EPC, and network 2 and network 4 indicated by network identifier list 2 can provide a connection to 5GC. Among them, the networks indicated by network identifier list 1 (i.e., network 1 and network 2) and the networks indicated by network identifier list 2 (network 2 and network 4) may overlap, that is, network 2 can provide both a connection to EPC and a connection to 5GC.

Among them, an element may include at least one of the following: network identifier (such as PLMN ID), index, etc. Here, the index may be the index of a first network in other network identifier lists.

[0062] Exemplarily, assume that at least one network identification list includes Network Identification List 1 and Network Identification List 2. Network Identification List 1 indicates Network 1 and Network 2, and Network Identification List 2 indicates Network 2 and Network 4. Then, Network Identification List 1 may include 2 elements, such as PLMN ID1 and PLMN ID2. PLMN ID1 is the PLMN ID of Network 1, and PLMN ID2 is the PLMN ID of Network 2. Network Identification List 2 may include 2 elements, such as index = 1, PLMN ID3. index = 1 is the index of Network 2 in Network Identification List 1, and PLMN ID3 is the PLMN ID of Network 4.

[0063] In some embodiments of the present application, the above first indication information may include at least one of the following:

[0064] At least one bitmap (such as the first bitmap in the following embodiments);

[0065] At least one list (such as the first list in the following embodiments);

[0066] At least one indication information (such as the second indication information in the following embodiments).

[0067] Wherein, one bit in each bitmap is used to indicate whether a first network indicated by a network identification list supports emergency services. A list includes the network identification or index of the first network that supports or does not support emergency services indicated by a network identification list. An indication information is used to indicate whether a first network indicated by a network identification list supports emergency services.

[0068] Next, taking the first indication information as different information respectively as an example, specific solutions for the first indication information to indicate whether each first network supports providing emergency services will be illustrated.

[0069] Example 1: The first indication information includes at least one first bitmap.

[0070] In some embodiments of the present application, each network identification list in the above at least one network identification list includes at least one element, and each element indicates a first network. Each first network is used to provide a first core network connection. When the first indication information includes at least one first bitmap, any one of the following is satisfied between the at least one network identification list and the at least one first bitmap:

[0071] When the first cell supports connection to multiple first core networks, the number of at least one network identification list is multiple, and the number of at least one first bitmap is multiple. The number of multiple network identification lists is equal to the number of multiple first bitmaps. Each first bitmap corresponds to a network identification list. Each bit in each first bitmap corresponds to each element in the corresponding network identification list in sequence;

[0072] When the first cell supports connection to multiple first core networks, the number of at least one network identification list is multiple, and the number of at least one first bitmap is one. One first bitmap includes multiple bit groups. Each bit group corresponds to a network identification list. Each bit in each bit group corresponds to each element in the corresponding network identification list in sequence;

[0073] When the first cell supports connection to one first core network, the number of at least one network identification list is one, and the number of at least one first bitmap is one. Each bit in one first bitmap corresponds to each element in one network identification list in sequence;

[0074] Wherein, each bit in each of the at least one first bitmaps is used to indicate whether the corresponding first network supports emergency services, and each first core network is different.

[0075] In some embodiments of the present application, when the number of at least one network identification list is multiple, and the number of at least one first bitmap is multiple, and the number of multiple network identification lists is equal to the number of multiple first bitmaps, for each of the at least one first bitmaps, the first bit in one first bitmap corresponds to the first element in the corresponding one network identification list, and this first bit is used to indicate whether the first network indicated by this first element supports emergency services. The second bit in this first bitmap corresponds to the second element in the corresponding one network identification list, and this second bit is used to indicate whether the other first network indicated by this second element supports emergency services, and so on, until the last bit in this first bitmap corresponds to the last element in the corresponding one network identification list, and this last bit is used to indicate whether the last first network indicated by this last element supports emergency services.

[0076] Optionally, when a bit takes a value of 1, this bit is used to indicate that the corresponding first network supports emergency services. When a bit takes a value of 0, this bit is used to indicate that the corresponding first network does not support emergency services.

[0077] Exemplarily, assume that the value of the first bit is 1, then the first bit is used to indicate that a first network indicated by the first element supports emergency services. In the case where the value of the first bit is 0, the first bit is used to indicate that a first network indicated by the first element does not support emergency services.

[0078] Optionally, when the number of at least one network identifier list is multiple and the number of at least one first bitmap is multiple, and the number of multiple network identifier lists is equal to the number of multiple first bitmaps, the specific signaling format of at least one first bitmap is as follows:

[0079]

[0080] In some embodiments of the present application, when the number of at least one network identifier list is multiple and the number of at least one first bitmap is one, for each bit group in the multiple bit groups, the first bit in a bit group corresponds to the first element in the corresponding network identifier list, and the first bit is used to indicate whether a first network indicated by the first element supports emergency services. The second bit in the bit group corresponds to the second element in the corresponding network identifier list, and the second bit is used to indicate whether another first network indicated by the second element supports emergency services, and so on, until the last bit in the bit group corresponds to the last element in the corresponding network identifier list, and the last bit is used to indicate whether the last first network indicated by the last element supports emergency services.

[0081] It can be understood that the terminal has the ability to obtain / read the above-mentioned one first bitmap and each network identifier list.

[0082] Optionally, each bit group corresponds to the corresponding network identifier list in sequence one by one.

[0083] Optionally, the length of one first bitmap is equal to the sum of the lengths of multiple network identifier lists.

[0084] Optionally, when the number of at least one network identifier list is multiple and the number of at least one first bitmap is one, the specific signaling format of at least one first bitmap is as follows:

[0085]

[0086] In some embodiments of the present application, when the number of at least one network identification list is one and the number of at least one first bitmap is one, for each first bitmap in the at least one first bitmap, the first bit in a first bitmap corresponds to the first element in the corresponding one network identification list, and this first bit is used to indicate whether a first network indicated by this first element supports emergency services. The second bit in this first bitmap corresponds to the second element in the corresponding one network identification list, and this second bit is used to indicate whether another first network indicated by this second element supports emergency services, and so on, until the last bit in this first bitmap corresponds to the last element in the corresponding one network identification list, and this last bit is used to indicate whether the last first network indicated by this last element supports emergency services.

[0087] It can be seen that the embodiments of the present application provide the relationship that needs to be satisfied between at least one network identification list and at least one first bitmap when the first indication information includes at least one first bitmap. In subsequent steps, the terminal can accurately determine whether each first network provided / indicated by the first cell supports emergency services based on this relationship. Therefore, the terminal can accurately determine whether it can obtain emergency services from the first cell. Further, the terminal can determine from which network it can obtain emergency services.

[0088] Example 2: The first indication information includes at least one first list.

[0089] In some embodiments of the present application, each network identification list in the at least one network identification list includes at least one element, each element indicates a first network, and each first network is used to provide a first core network connection. When the first indication information includes at least one first list, any one of the following is satisfied between the at least one network identification list and the at least one first list:

[0090] When the first cell supports connecting to multiple first core networks, the number of at least one network identification list is multiple and the number of at least one first list is multiple. The number of multiple network identification lists is equal to the number of multiple first lists. Each first list corresponds to one network identification list, and each first list includes the network identifications of the first networks that support or do not support emergency services indicated by the corresponding network identification list.

[0091] When a first cell supports connection to multiple first core networks, the number of at least one network identification list is multiple, and the number of at least one first list is multiple. The number of multiple network identification lists is equal to the number of multiple first lists. Each first list corresponds to a network identification list, and each first list includes indexes of first networks that support or do not support emergency services indicated by the corresponding network identification list.

[0092] When a first cell supports connection to multiple first core networks, the number of at least one network identification list is multiple, and the number of at least one first list is one. One first list includes multiple network identification groups. Each network identification group corresponds to a network identification list, and each network identification group includes network identifications of first networks that support or do not support emergency services indicated by the corresponding network identification list.

[0093] When a first cell supports connection to multiple first core networks, the number of at least one network identification list is multiple, and the number of at least one first list is one. One first list includes multiple network identification groups. Each network identification group corresponds to a network identification list, and each network identification group includes indexes of first networks that support or do not support emergency services indicated by the corresponding network identification list.

[0094] When a first cell supports connection to one first core network, the number of at least one network identification list is one, and the number of at least one first list is one. One first list includes network identifications of first networks that support or do not support emergency services indicated by the network identification list.

[0095] When a first cell supports connection to one first core network, the number of at least one network identification list is one, and the number of at least one first list is one. One first list includes indexes corresponding to first networks that support or do not support emergency services indicated by one network identification list.

[0096] Wherein, each first core network is different from each other.

[0097] In some embodiments of the present application, the above network identification may specifically be a PLMD ID, and the index of the above first network may specifically be the index of the first network in the network identification list.

[0098] In some embodiments of the present application, when the number of at least one network identification list is multiple, and the number of at least one first list is multiple, and the number of multiple network identification lists is equal to the number of multiple first lists, taking the first list including indexes of the first network as an example, the specific signaling format of at least one first list is as follows:

[0099]

[0100] In some embodiments of the present application, when the number of at least one network identification list is multiple and the number of at least one first list is one, the above index can be one-dimensional or multi-dimensional. If it is one-dimensional, for example, the index of the first element in a network identification list is 1, the index of the second element is 2, and the index of the nth element is n. The index of the first element in another network identification list is n + 1, the index of the second element is n + 2, and the index of the mth element is m. If it is multi-dimensional, taking the existence of two network identification lists as an example (i.e., the above index is two-dimensional), for example, for the ith element in this one network identification list, the index value of the jth element in the other network identification list is (i, j). Wherein, this one network identification list has n elements, and the other network identification list has m elements.

[0101] In some embodiments of the present application, when the number of at least one network identification list is multiple and the number of at least one first list is one, taking the first list including the index of the first network as an example, the specific signaling format of at least one first list is as follows:

[0102]

[0103] It can be seen from this that the embodiments of the present application provide the relationship that needs to be satisfied between at least one network identification list and at least one first list when the first indication information includes at least one first list. In this way, in subsequent steps, the terminal can accurately determine whether each first network of the first cell supports emergency services based on this relationship. Therefore, the terminal can accurately determine whether it can obtain emergency services from the first cell. Further, the terminal can determine from which network it can obtain emergency services.

[0104] Example 3: The first indication information includes at least one second indication information.

[0105] In some embodiments of the present application, each network identification list includes at least one element, each element indicates a first network, and each first network is used to provide a first core network connection. When the first indication information includes at least one second indication information, at least one of the following is satisfied between at least one network identification list and at least one second indication information:

[0106] When the first cell supports connecting to multiple first core networks, the number of at least one network identification list is multiple and the number of at least one second indication information is multiple. The multiple second indication information is located in multiple third lists, each third list corresponds to a network identification list, and each second indication information in each third list corresponds to each element in the corresponding network identification list in sequence one by one;

[0107] When the first cell supports connecting to multiple first core networks, the number of at least one network identification list is multiple, and the number of at least one second indication information is multiple. The multiple second indication information is located in a fourth list, and the fourth list includes multiple indication information groups. Each indication information group corresponds to a network identification list, and each second indication information in each indication information group corresponds to each element in the corresponding network identification list in sequence;

[0108] When the first cell supports connecting to one first core network, the number of at least one network identification list is one. Each first network indicated by each element in one network identification list is used to provide a connection to one first core network. At least one second indication information is located in a fifth list, and each second indication information in the fifth list corresponds to each element in one network identification list in sequence;

[0109] At least one second indication information is located in at least one network identification list, and each second indication information corresponds to each element in each network identification list;

[0110] Wherein, the above-mentioned second indication information is used to indicate whether the corresponding first network supports emergency services, and each first core network is different.

[0111] In some embodiments of the present application, when the number of at least one network identification list is multiple, and the number of at least one second indication information is multiple, and the multiple second indication information is located in multiple third lists, the specific signaling format of at least one second indication information is as follows:

[0112] SystemInformationBlockType1-v1900-IEs::=SEQUENCE{

[0113] imsEmergencySupportForEPCList::=SEQUENCE(SIZE(1..maxPLMN-r11)) OFImsEmergencySupportForEPC OPTIONAL,--Need OR

[0114] imsEmergencySupportFor5GCList SEQUENCE(SIZE(1..maxPLMN-r11)) OFImsEmergencySupportFor5GC OPTIONAL,--Need OR

[0115] }

[0116] Ims-EmergencySupportForEPC::= ENUMERATED{true}

[0117] Ims-EmergencySupportFor5GC::= ENUMERATED{true}

[0118] In some embodiments of the present application, when the number of at least one network identification list is multiple and the number of at least one second indication information is multiple, and the multiple second indication information is located in the fourth list, the specific signaling format of at least one second indication information is as follows:

[0119] SystemInformationBlockType1-v1900-IEs::= SEQUENCE{

[0120] imsEmergencySupportForEPCAnd5GCList::= SEQUENCE(SIZE(1..maxPLMNEPCAnd5GC)) OF ImsEmergencySupportForEPCAnd5GC OPTIONAL,--Need OR

[0121] }

[0122] Ims-EmergencySupportForEPCAnd5GC::= ENUMERATED

[0123] {true}

[0124] In some embodiments of the present application, when the number of at least one network identification list is one and at least one second indication information is located in the fifth list, the specific signaling format of at least one second indication information is as follows:

[0125]

[0126] Thus, it can be seen that the embodiments of the present application provide the relationship that needs to be satisfied between at least one network identification list and at least one second indication information when the first indication information includes at least one second indication information. In subsequent steps, the terminal can accurately determine whether each first network of the first cell supports emergency services based on this relationship. Therefore, the terminal can accurately determine whether it can obtain emergency services from the first cell. Further, the terminal can determine from which network it can obtain emergency services.

[0127] Step 102: The terminal determines whether it can obtain emergency services from the first cell according to at least one network identification list and the first indication information.

[0128] In some embodiments of the present application, the terminal may determine whether there is a first network that supports emergency services in the first network for providing the core network supported by the terminal or the core network connection selected by the terminal, according to at least one network identifier list and first indication information, so that the terminal can determine whether it can obtain emergency services from the first cell.

[0129] Optionally, when the terminal determines that there is a first network that supports emergency services in the first network for providing the core network supported by the terminal or the core network connection selected by the terminal, the terminal determines that it can obtain emergency services from the first cell. Or, when the terminal determines that there is no first network that supports emergency services in the first network for providing the core network supported by the terminal or the core network connection selected by the terminal, the terminal determines that it cannot obtain emergency services from the first cell.

[0130] In some embodiments of the present application, step 102 above may be specifically implemented by any one of the following steps 102a to 102c.

[0131] Step 102a: When the first cell supports connecting to multiple first core networks, the terminal determines, according to multiple first bitmaps and multiple network identifier lists, whether each first network indicated by each network identifier list supports providing emergency services through the first core network.

[0132] Step 102b: When the first cell supports connecting to multiple first core networks, the terminal determines, according to one first bitmap and multiple network identifier lists, whether each first network indicated by each network identifier list supports providing emergency services through the first core network.

[0133] Step 102c: When the first cell supports connecting to one first core network, the terminal determines, according to one first bitmap and one network identifier list, whether each first network indicated by the one network identifier list supports providing emergency services through the first core network.

[0134] Thus, it can be seen that when the first cell supports connecting to different numbers of first core networks, the terminal can also accurately determine, according to different numbers of first bitmaps and different numbers of network identifier lists, whether each first network indicated by each network identifier list supports providing emergency services through the first core network, so as to accurately determine whether the terminal can obtain emergency services from the first cell.

[0135] In some embodiments of the present application, step 102 above may be specifically implemented by any one of the following steps 102d to 102f.

[0136] Step 102d: When the first cell supports connection to multiple first core networks, the terminal determines, based on multiple first lists and multiple network identifier lists, whether each first network indicated by each network identifier list supports providing emergency services via the first core network.

[0137] Step 102e: When the first cell supports connection to multiple first core networks, the terminal determines, based on one first list and multiple network identifier lists, whether each first network indicated by each network identifier list supports providing emergency services via the first core network.

[0138] Step 102f: When the first cell supports connection to one first core network, the terminal determines, based on one first list and one network identifier list, whether each first network indicated by each network identifier list supports providing emergency services via the first core network.

[0139] Thus, it can be seen that when the first cell supports connection to different numbers of first core networks, the terminal can also accurately determine, based on different numbers of first lists and different numbers of network identifier lists, whether each first network indicated by each network identifier list supports providing emergency services via the first core network, so as to accurately determine whether the terminal can obtain emergency services from the first cell.

[0140] In some embodiments of the present application, the above step 102 can be specifically implemented by any one of the following steps 102g to 102j.

[0141] Step 102g: When the first cell supports connection to multiple first core networks, the terminal determines, based on multiple third lists and multiple network identifier lists, whether each first network indicated by each network identifier list supports providing emergency services via the first core network;

[0142] Step 102h: When the first cell supports connection to multiple first core networks, the terminal determines, based on a fourth list and multiple network identifier lists, whether each first network indicated by each network identifier list supports providing emergency services via the first core network;

[0143] Step 102i: When the first cell supports connection to one first core network, the terminal determines, based on a fifth list and one network identifier list, whether each first network indicated by the one network identifier list supports providing emergency services via the first core network;

[0144] Step 102j: The terminal determines, based on at least one network identifier list and at least one second indication information, whether each first network of each network identifier list supports providing emergency services via the first core network.

[0145] It can be seen that when the first cell supports connecting to different numbers of first core networks, the terminal can also accurately determine whether each first network indicated by each network identifier list supports providing emergency services through the first core network according to different numbers of second indication information and different numbers of network identifier lists, so that it can accurately determine whether the terminal can obtain emergency services from the first cell.

[0146] In some embodiments of the present application, step 102 above can be specifically implemented by at least one of the following step 102k and step 102l.

[0147] Step 102k: The Non-Access Stratum (NAS) of the terminal determines whether it can obtain emergency services from the first cell according to at least one network identifier list and the first indication information.

[0148] Step 102l: The Access Stratum (AS) of the terminal determines whether it can obtain emergency services from the first cell according to at least one network identifier list and the first indication information.

[0149] It can be seen that since both the AS and / or NAS of the terminal can determine whether it can obtain emergency services from the first cell according to at least one network identifier list and the first indication information, rather than only a certain layer of the terminal can determine whether it can obtain emergency services from the first cell, the flexibility of determining whether it can obtain emergency services from the first cell can be improved.

[0150] In some embodiments of the present application, in combination Figure 3 , such as Figure 4 shown, after the above step 101 and before the above step 102, the service acquisition determination method provided by the embodiments of the present application may further include the following step 201.

[0151] Step 201: The AS of the terminal submits first information to the NAS of the terminal.

[0152] In the embodiments of the present application, the above first information includes any one of the following:

[0153] At least part of the network identifier list and at least part of the first bitmap;

[0154] The network identifier of the second network in at least one first network;

[0155] Wherein, the above second network supports emergency services, and the second network is used to provide a second core network connection, and the second core network satisfies at least one of the following:

[0156] The first core network supported by the connection of the terminal in at least one first core network;

[0157] The NAS of the terminal in at least one first core network indicates the selected first core network.

[0158] In some embodiments of the present application, when the NAS of the terminal determines whether it can obtain emergency services from the first cell according to at least one network identification list and the first indication information, the first information includes at least part of the network identification list and at least part of the first bitmap; when the AS of the terminal determines whether it can obtain emergency services from the first cell according to at least one network identification list and the first indication information, the first information includes the network identification of the second network in at least one first network.

[0159] In some embodiments of the present application, at least part of the network identification list includes a first network identification list, and the first network indicated by the first network identification list is used to provide the connection of the second core network; at least part of the first bitmap includes a second bitmap, and at least part of the bits in the second bitmap correspond one-to-one with the elements in the first network identification list.

[0160] Thus, it can be seen that since the AS of the terminal can submit to the NAS of the terminal only the information related to the first core network supported by the terminal for connection or the first core network selected by the NAS indication of the terminal, without submitting all of the first information, the amount of information submitted by the AS of the terminal to the NAS of the terminal can be reduced.

[0161] In some embodiments of the present application, in combination Figure 3 , such as Figure 5 shown, after the above step 101 and before the above step 102, the service acquisition determination method provided by the embodiments of the present application may further include the following step 202.

[0162] Step 202: The AS of the terminal submits second information to the NAS of the terminal.

[0163] In the embodiments of the present application, the above second information includes any one of the following:

[0164] At least part of the network identification list and at least part of the first list;

[0165] The network identification of the second network in at least one first network;

[0166] Wherein, the above second network supports emergency services, and the second network is used to provide the connection of the second core network, and the second core network satisfies at least one of the following:

[0167] The first core network supported by the terminal in at least one first core network for connection;

[0168] The first core network selected by the NAS indication of the terminal in at least one first core network.

[0169] In some embodiments of the present application, when the NAS of the terminal determines whether it can obtain emergency services from the first cell according to at least one network identifier list and first indication information, the first information includes at least part of the network identifier list and at least part of the first list; when the AS of the terminal determines whether it can obtain emergency services from the first cell according to at least one network identifier list and first indication information, the first information includes the network identifier of the second network in at least one first network.

[0170] In some embodiments of the present application, at least part of the network identifier list includes a first network identifier list, and the first network indicated by the first network identifier list is used to provide a connection to the second core network; at least part of the first list includes a second list, and at least part of the first networks corresponding to the network identifiers in the second list are subsets of the first network indicated by the first network identifier list, or at least part of the first networks corresponding to the indexes in the second list are subsets of the first network indicated by the first network identifier list.

[0171] It can be seen that since the AS of the terminal can submit only the information related to the first core network supported by the terminal or the first core network selected by the NAS of the terminal to the NAS of the terminal, without submitting all the first information, the amount of information submitted by the AS of the terminal to the NAS of the terminal can be reduced.

[0172] In some embodiments of the present application, in combination Figure 3 , such as Figure 6 shown, after the above step 101 and before the above step 102, the service acquisition judgment method provided by the embodiments of the present application may further include the following step 203.

[0173] Step 203: The AS of the terminal submits third information to the NAS of the terminal.

[0174] In the embodiments of the present application, the above third information includes any one of the following:

[0175] At least part of the network identifier list and at least part of the second indication information;

[0176] The network identifier of the second network in at least one first network;

[0177] Wherein, the second network supports emergency services, the second network is used to provide a second core network connection, and the second core network satisfies at least one of the following:

[0178] The first core network supported by the terminal in at least one first core network;

[0179] The first core network selected by the NAS of the terminal in at least one first core network.

[0180] In some embodiments of the present application, when the NAS of the terminal determines whether it can obtain emergency services from the first cell according to at least one network identification list and the first indication information, the first information includes at least part of the network identification list and at least part of the second indication information; when the AS of the terminal determines whether it can obtain emergency services from the first cell according to at least one network identification list and the first indication information, the first information includes the network identification of a second network in at least one first network.

[0181] In some embodiments of the present application, at least part of the network identification list includes a first network identification list, and the first network indicated by the first network identification list is used to provide a connection to a second core network; at least part of the second indication information includes third indication information, and the third indication information is used to indicate whether the first network providing the second core network connection supports emergency services.

[0182] It can be seen that since the AS of the terminal can submit only information related to the first core network supported by the terminal for connection or the first core network selected by the NAS indication of the terminal to the NAS of the terminal, without submitting all of the first information, the amount of information submitted by the AS of the terminal to the NAS of the terminal can be reduced.

[0183] In some embodiments of the present application, step 102 above can be specifically implemented by the following step 102m or step 102n.

[0184] Step 102m: When the terminal supports connecting to a second core network in at least one first core network and the first indication information indicates that any one of the first networks for providing the second core network connection supports providing emergency services, the terminal determines that it can obtain emergency services from the first cell.

[0185] In the embodiments of the present application, if the terminal supports connecting to a second core network in at least one first core network and the first indication information indicates that any one of the first networks for providing the second core network connection supports providing emergency services, it can be considered that after the terminal sends an emergency registration to the second core network through any one of the first networks, the second core network will accept the emergency registration, so that the terminal can obtain emergency services from the first cell. Therefore, the terminal determines that it can obtain emergency services from the first cell.

[0186] It can be seen that the terminal can accurately determine that it can obtain emergency services from the first cell when the terminal supports connecting to a second core network in at least one first core network and the first indication information indicates that any one of the first networks for providing the second core network connection supports providing emergency services.

[0187] In some embodiments of the present application, step 102m above can be specifically implemented by the following step 102m1.

[0188] Step 102m1: When the terminal supports connecting to a second core network in at least one first core network and the first indication information indicates that any one of the first networks for providing the second core network connection supports providing emergency services, the terminal determines that it can obtain emergency services from the first cell through the second core network.

[0189] In some embodiments of the present application, in subsequent steps, the terminal may send an emergency registration to the second core network to obtain emergency services from the first cell.

[0190] Thus, it can be known that since the terminal can accurately determine that it can obtain emergency services from the first cell through the second core network, in subsequent steps, the terminal can directly send an emergency registration to the second core network to quickly obtain emergency services from the first cell.

[0191] Step 102n: When the terminal supports connecting to a second core network in at least one first core network and the first indication information indicates that each of the first networks for providing the second core network connection does not support providing emergency services, the terminal determines that it cannot obtain emergency services from the first cell.

[0192] In the embodiments of the present application, if the terminal supports connecting to a second core network in at least one first core network and the first indication information indicates that each of the first networks for providing the second core network connection does not support providing emergency services, it can be considered that after the terminal sends an emergency registration to the second core network through each of these first networks, the second core network will reject the emergency registration. Therefore, the terminal determines that it cannot obtain emergency services from the first cell.

[0193] Thus, it can be known that the terminal can accurately determine that it cannot obtain emergency services from the first cell when the terminal supports connecting to a second core network in at least one first core network and the first indication information indicates that each of the first networks for providing the second core network connection does not support providing emergency services.

[0194] In some embodiments of the present application, the above step 102n can be specifically implemented through the following step 102n1.

[0195] Step 102n1: When the terminal supports connecting to a second core network in at least one first core network and the first indication information indicates that each of the first networks for providing the second core network connection does not support providing emergency services, the terminal determines that it cannot obtain emergency services from the first cell through the second core network.

[0196] In some embodiments of the present application, in subsequent steps, the terminal may register to other cells to obtain emergency services from other cells.

[0197] It can be seen that since the terminal can accurately determine that it cannot obtain emergency services from the first cell through the second core network, in subsequent steps, the terminal can directly register to other messages to quickly obtain emergency services from other cells.

[0198] An embodiment of the present application provides a method for judging service acquisition. The terminal can obtain at least one network identifier list and a first indication information provided by the first cell. The first cell supports connecting to at least one first core network. Each network identifier list is used to indicate at least one first network, and the first network is used to provide a connection to the first core network. The first indication information is used to indicate whether each first network supports providing emergency services. Thus, the terminal can judge whether it can obtain emergency services from the first cell according to the at least one network identifier list and the first indication information. Since the first cell can provide at least one network identifier list and the first indication information, the at least one network identifier list is used to indicate each first network of the first cell, and the first indication information can indicate whether each first network providing a connection to each first core network supports providing emergency services. In this way, the terminal can judge whether it can obtain emergency services from the first cell according to the at least one network identifier list and the first indication information, and further judge the network that supports emergency services. In this way, the terminal can directly initiate an emergency registration through the first network indicated by the first indication information that supports providing emergency services, so that the core network supported by the terminal can accept the emergency registration without unnecessary attempts, thus reducing the delay for the terminal to obtain emergency services.

[0199] In some embodiments of the present application, in combination with Figure 3 , such as Figure 7 shown, after the above step 102, the method for judging service acquisition provided by the embodiment of the present application may further include the following step 103.

[0200] Step 103: When the terminal judges that it can obtain emergency services from the first cell, the terminal considers the first cell as a candidate cell for cell selection or cell reselection.

[0201] In some embodiments of the present application, the terminal can determine the first cell as a high-priority candidate cell for cell selection or cell reselection.

[0202] It can be seen that since when the terminal judges that it can obtain emergency services from the first cell, the terminal can determine the first cell as a candidate cell for cell selection or cell reselection. In subsequent steps, the terminal can perform cell selection or cell reselection to register to the first cell. Therefore, it can ensure that the terminal can obtain emergency services in a timely manner.

[0203] In some embodiments of the present application, after step 102 above, the service acquisition determination method provided by the embodiments of the present application may further include the following step 104.

[0204] Step 104: When the terminal determines that it can obtain emergency services from the first cell, the terminal performs at least one of the following steps:

[0205] When the terminal supports accessing a second core network in at least one first core network, if the network selected or registered by the terminal does not match the second network in at least one first network, the terminal selects the second network, and the second network is used to provide a second core network connection, and the second network supports providing emergency services;

[0206] When the terminal supports accessing a second core network and a third core network in at least one first core network, if the type of core network selected by the terminal is the second core network, and any one of the first networks used to provide a third core network connection supports providing emergency services, the terminal selects the third core network and selects a third network in at least one first network, and the third network is used to provide a third core network connection, and the third network supports providing emergency services.

[0207] It can be understood that the terminal can select a first network that is used to provide the core network supported by the terminal and supports providing emergency services.

[0208] Thus, it can be seen that since when the terminal determines that it can obtain emergency services from the first cell, the terminal can perform at least one step to ensure that the terminal can select a first network that is used to provide the core network supported by the terminal and supports providing emergency services. In this way, in subsequent steps, the terminal can quickly obtain emergency services from the first cell through the selected first network.

[0209] Figure 8 The flowchart shows a service acquisition determination method provided by an embodiment of the present application. As Figure 8 shown, a service acquisition determination method provided by an embodiment of the present application may include the following step 301.

[0210] Step 301: The network-side device sends at least one network identifier list corresponding to the first cell and first indication information to the terminal.

[0211] In the embodiments of the present application, the above-mentioned first cell supports connecting to at least one first core network. Each network identifier list is used to indicate at least one first network, and the first network is used to provide a connection to the first core network. The first indication information is used to indicate whether each first network supports providing emergency services.

[0212] It should be noted that the descriptions of the network identifier list, the first indication information, the first core network, and the first network can refer to the specific descriptions in the foregoing embodiments, and are not elaborated herein in the embodiments of the present application.

[0213] In the embodiments of the present application, the foregoing at least one network identifier list and the first indication information are used for the terminal to determine whether it can obtain emergency services from the first cell.

[0214] It should be noted that the description of the terminal determining whether it can obtain emergency services from the first cell according to the at least one network identifier list and the first indication information can refer to the specific descriptions in the foregoing embodiments, and is not elaborated herein in the embodiments of the present application.

[0215] The embodiments of the present application provide a method for judging service acquisition. The network-side device can send at least one network identifier list corresponding to the first cell and the first indication information to the terminal. Among them, the first cell supports connecting to at least one first core network, each network identifier list is used to indicate at least one first network, the first network is used to provide the connection of the first core network, the first indication information is used to indicate whether each first network supports providing emergency services, and the at least one network identifier list and the first indication information are used for the terminal to determine whether it can obtain emergency services from the first cell. Since the network-side device can indicate at least one network identifier list corresponding to the first cell and the first indication information to the terminal, the at least one network identifier list is used to indicate each first network of the first cell, and the first indication information can indicate whether each first network providing the connection of each first core network supports providing emergency services. In this way, the terminal can determine whether it can obtain emergency services from the first cell according to the at least one network identifier list and the first indication information, and further determine the network that supports emergency services. In this way, the terminal can directly initiate an emergency registration through the first network indicated by the first indication information to support providing emergency services, so that the core network supported by the terminal can accept the emergency registration without unnecessary attempts, thereby reducing the delay for the terminal to obtain emergency services.

[0216] For the method for judging service acquisition provided in the embodiments of the present application, the execution subject can be a service acquisition judgment device. In the embodiments of the present application, taking the service acquisition judgment device executing the service acquisition judgment method as an example, the service acquisition judgment device provided in the embodiments of the present application is described.

[0217] Figure 9 Shows a possible structural schematic diagram of the service acquisition judgment device provided in the embodiments of the present application. As Figure 9As shown in the figure, the service acquisition judgment device 30 provided by the embodiment of the present application may include: an acquisition module 31, configured to acquire at least one network identifier list and first indication information provided by a first cell, where the first cell supports connection to at least one first core network, each network identifier list is used to indicate at least one first network, the first network is used to provide connection to the first core network, and the first indication information is used to indicate whether each first network supports providing emergency services; a processing module 32, configured to determine whether emergency services can be acquired from the first cell according to the at least one network identifier list and the first indication information acquired by the acquisition module 31.

[0218] The embodiment of the present application provides a service acquisition judgment device. Since the first cell can provide at least one network identifier list and first indication information, the at least one network identifier list is used to indicate each first network of the first cell, and the first indication information can indicate whether each first network providing connection to each first core network supports providing emergency services. In this way, the judgment device can determine whether emergency services can be acquired from the first cell according to the at least one network identifier list and the first indication information, and further determine the network supporting emergency services.
