The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The first embodiment,
An embodiment of the present invention provides an identifier allocation method, which is applied to a network device, and as shown in fig. 1, the method includes:
step 11: determining the type of user equipment based on service access operation of the user equipment;
step 12: allocating a temporary identifier to the user equipment based on the type of the user equipment;
the temporary identifier at least comprises a first type temporary identifier and a second type temporary identifier; when the first type temporary identification is distributed to user equipment, the user equipment is enabled to use the temporary identification in the coverage range of one base station; when the second type temporary identifier is distributed to the user equipment, the user equipment uses the same temporary identifier in the coverage range of N base stations to be experienced in the process of processing the first service; wherein N is a positive integer greater than or equal to two.
Here, the user equipment may be a device with a mobile communication function, such as a mobile phone, a tablet computer, and the like.
The service access operation of the user equipment may be: when the user equipment needs to process the corresponding service, the initiated access process, or the access counting operation performed for responding to the request of the service initiating terminal;
for example, at least: sending an access pilot frequency sequence to a server; sending random access response information to the user equipment by the server; the user equipment randomly accesses the network based on the response information.
The allocating a temporary identifier to the user equipment based on the type of the user equipment includes: if the user equipment is first-class user equipment, allocating first-class temporary identifications to the user equipment; and if the user equipment is second-class user equipment, allocating second-class temporary identifications to the user equipment.
Different types of user equipment are distinguished in this embodiment: the first type of user equipment is small data or users moving infrequently; the second category of user equipment is big data, frequently moving users.
The consideration of the frequent movement may be a comprehensive consideration according to parameters such as connection duration, user movement rate, user movement direction, and site coverage, and may be calculated, for example, in the following manner: service duration user mobility rate/site diameter.
In this embodiment, the first service may be a service to be processed by a user equipment currently accessing to a base station.
Preferably, the present embodiment provides an operation manner for determining the type of the user equipment:
the determining the type of the user equipment based on the service access operation of the user equipment comprises:
acquiring the type of an access pilot sequence in service access operation of user equipment;
if the type of the access pilot frequency sequence is a first preset type, determining that the user equipment is a first type of user equipment; and if the type of the access pilot frequency sequence is a second preset type, determining that the user equipment is a second type of user equipment.
For example, as shown in fig. 2, step 21: the user equipment selects different types of access pilot frequency sequences according to the types and sends the access pilot frequency sequences to the network equipment side;
step 22: the network equipment determines the type of the user equipment according to the received access pilot frequency sequence, further determines the type of the corresponding temporary identifier, and returns the type of the corresponding temporary identifier to the user equipment through random access response information.
The method for determining the type of the user equipment can be that the mobility size M and the service connection duration T of the user equipment are expected, a preset or system broadcast mobility threshold MTH and a service connection duration threshold TTH are compared, when the M < MTH or the T < TTH, the type of the user equipment is determined to be the first type of user equipment, then an access pilot frequency sequence of the first preset type is selected, and otherwise, an access pilot frequency sequence of the second preset type is selected.
In addition, the classification of the user equipment described in this embodiment may be determined by whether the service to be processed is a large data service or a small data service, and the determination of the large data and the small data may be performed by using the service types: for example, the video is big data, the instant messaging chat is small data, and the determination can be performed by defining a certain service rate threshold, or setting a ratio according to the percentage of the service rate of other users of the current service rate station system. It will be appreciated that different data types may be served by different types of sites and that the site diameter references may be different.
Further, in this embodiment, determining the classification of the ue may also determine a type corresponding to the ue according to different carrier orientations, so as to determine different types of temporary identifiers corresponding to the ue; for example, the correspondence between the codes of the carriers and the types of the user equipments may be preset.
The example is simply performed: user identities can be divided into two broad categories: first, the first type temporary identifier is applicable to type 1) low mobility (mobility, which may consider relative mobility, such as mobility relative to site coverage, and the metric is: the number of sites traversed in unit time) or the service connection time is short (including users whose packet interval is greater than a threshold LTH in the service connection process, such services have enough time to perform reconfiguration behavior caused by handover, and the connection time of such user services can be set to be the length of a single packet), and such users are characterized in that in the service connection process, it is basically difficult to walk through one base station or the number of base stations with a certain set threshold, so that the corresponding user identifiers can be released or updated quickly and do not affect user experience, and the identifiers of such users can be allocated by using traditional site-based identifiers, thereby improving the reuse rate of the user identifiers;
secondly, the second type temporary identifier is suitable for the user identifier of the user type 2), and the user identifier is characterized in that the station-crossing movement is frequent, the service continuity is strong, the user identifier is not good due to frequent switching process and user identifier update, the user identifier available for a long time needs to be ensured, and the seamless experience of the service process can be realized.
In the embodiment, for the generation mode of the first-type temporary identifier, different base stations accessed to different base stations can be used for generating different C-RNTIs as the first-type temporary identifiers;
the generation manner for the second type temporary identifier may be an identifier generated by using an IMSI identifier or an IMSI, or an identifier reserved by the network, and is not bound to any base station.
Therefore, by adopting the scheme, the type of the user equipment is determined according to the access operation of the user equipment, and at least two types of temporary identifications are distributed to the user equipment according to the type of the user equipment. In this way, different types of temporary identifications can be allocated according to the types of the user equipment, and the requirements of the development of the mobile communication technology can be met by using the different types of temporary identifications.
In addition, when the user equipment uses the second type temporary identifier, the same temporary identifier can be used when the same service is processed no matter the user equipment goes through several base stations. Therefore, the temporary identifier of the user equipment can be unbound with the base station, the user equipment is ensured to use the same temporary identifier in the same service processing process, the transparency of the user equipment is improved, the influence of switching operation on the user equipment is reduced, and the use experience of a user is improved.

An embodiment of the present invention provides an identifier allocation method, which is applied to a network device, and as shown in fig. 1, the method includes:
step 11: determining the type of user equipment based on service access operation of the user equipment;
step 12: allocating a temporary identifier to the user equipment based on the type of the user equipment;
the temporary identifier at least comprises a first type temporary identifier and a second type temporary identifier; when the first type temporary identification is distributed to user equipment, the user equipment is enabled to use the temporary identification in the coverage range of one base station; when the second type temporary identifier is distributed to the user equipment, the user equipment uses the same temporary identifier in the coverage range of N base stations to be experienced in the process of processing the first service; wherein N is a positive integer greater than or equal to two.
Here, the user equipment may be a device with a mobile communication function, such as a mobile phone, a tablet computer, and the like.
The service access operation of the user equipment may be: when the user equipment needs to process the corresponding service, the initiated access process, or the access counting operation performed for responding to the request of the service initiating terminal;
for example, at least: sending an access pilot frequency sequence to a server; sending random access response information to the user equipment by the server; the user equipment randomly accesses the network based on the response information.
The allocating a temporary identifier to the user equipment based on the type of the user equipment includes: if the user equipment is first-class user equipment, allocating first-class temporary identifications to the user equipment; and if the user equipment is second-class user equipment, allocating second-class temporary identifications to the user equipment.
Different types of user equipment are distinguished in this embodiment: the first type of user equipment is small data or users moving infrequently; the second category of user equipment is big data, frequently moving users.
The consideration of the frequent movement may be a comprehensive consideration according to parameters such as connection duration, user movement rate, user movement direction, and site coverage, and may be calculated, for example, in the following manner: service duration user mobility rate/site diameter.
In this embodiment, the first service may be a service to be processed by a user equipment currently accessing to a base station.
Preferably, the present embodiment provides another operation manner for determining the type of the user equipment:
the determining the type of the user equipment based on the service access operation of the user equipment comprises:
extracting user characteristic information from the connection request information of the service access operation of the user equipment;
judging whether the user characteristic information accords with a first preset condition, and if the user characteristic information accords with the first preset condition, determining that the user equipment is a first type of user equipment; otherwise, determining the user equipment as second type user equipment;
the first preset condition is that the service type in the user characteristic information is a small data service type, or the moving speed in the user characteristic information is lower than a speed threshold.
For example, as shown in fig. 3, the user equipment transmits a preamble sequence by transmitting an msg1 message; the network equipment carries out random access response according to the received msg1 and sends msg2 information to the user equipment; the user equipment sends a connection request to the network equipment through the msg3 message, and can add fields capable of indicating mobility and service connection duration when requesting the service, or directly judge by the network itself; the network device assigns an appropriate temporary identifier based on the determination of the user device type at the time of the connection establishment feedback (Msg 4).
The method for determining the type of the user equipment can be that the mobility size M and the service connection duration T of the user equipment are expected, a preset or system broadcast mobility threshold MTH and a service connection duration threshold TTH are compared, when the M < MTH or the T < TTH, the type of the user equipment is determined to be the first type of user equipment, then an access pilot frequency sequence of the first preset type is selected, and otherwise, an access pilot frequency sequence of the second preset type is selected.
In addition, the classification of the user equipment described in this embodiment may be determined by whether the service to be processed is a large data service or a small data service, and the determination of the large data and the small data may be performed by using the service types: for example, the video is big data, the instant messaging chat is small data, and the determination can be performed by defining a certain service rate threshold, or setting a ratio according to the percentage of the service rate of other users of the current service rate station system. It will be appreciated that different data types may be served by different types of sites and that the site diameter references may be different.
Further, in this embodiment, determining the classification of the ue may also determine a type corresponding to the ue according to different carrier orientations, so as to determine different types of temporary identifiers corresponding to the ue; for example, the correspondence between the codes of the carriers and the types of the user equipments may be preset.
The example is simply performed: user identities can be divided into two broad categories: first, the first type temporary identifier is applicable to type 1) low mobility (mobility, which may consider relative mobility, such as mobility relative to site coverage, and the metric is: the number of sites traversed in unit time) or the service connection time is short (including users whose packet interval is greater than a threshold LTH in the service connection process, such services have enough time to perform reconfiguration behavior caused by handover, and the connection time of such user services can be set to be the length of a single packet), and such users are characterized in that in the service connection process, it is basically difficult to walk through one base station or the number of base stations with a certain set threshold, so that the corresponding user identifiers can be released or updated quickly and do not affect user experience, and the identifiers of such users can be allocated by using traditional site-based identifiers, thereby improving the reuse rate of the user identifiers;
secondly, the second type temporary identifier is suitable for the user identifier of the user type 2), and the user identifier is characterized in that the station-crossing movement is frequent, the service continuity is strong, the user identifier is not good due to frequent switching process and user identifier update, the user identifier available for a long time needs to be ensured, and the seamless experience of the service process can be realized.
In the embodiment, for the generation mode of the first-type temporary identifier, different base stations accessed to different base stations can be used for generating different C-RNTIs as the first-type temporary identifiers;
the generation manner for the second type temporary identifier may be an identifier generated by using an IMSI identifier or an IMSI, or an identifier reserved by the network, and is not bound to any base station.
Therefore, by adopting the scheme, the type of the user equipment is determined according to the access operation of the user equipment, and at least two types of temporary identifications are distributed to the user equipment according to the type of the user equipment. In this way, different types of temporary identifications can be allocated according to the types of the user equipment, and the requirements of the development of the mobile communication technology can be met by using the different types of temporary identifications.
In addition, when the user equipment uses the second type temporary identifier, the same temporary identifier can be used when the same service is processed no matter the user equipment goes through several base stations. Therefore, the temporary identifier of the user equipment can be unbound with the base station, the user equipment is ensured to use the same temporary identifier in the same service processing process, the transparency of the user equipment is improved, the influence of switching operation on the user equipment is reduced, and the use experience of a user is improved.
Example III,
An embodiment of the present invention provides an identifier allocation method, which is applied to a network device, and as shown in fig. 1, the method includes:
step 11: determining the type of user equipment based on service access operation of the user equipment;
step 12: allocating a temporary identifier to the user equipment based on the type of the user equipment;
the temporary identifier at least comprises a first type temporary identifier and a second type temporary identifier; when the first type temporary identification is distributed to user equipment, the user equipment is enabled to use the temporary identification in the coverage range of one base station; when the second type temporary identifier is distributed to the user equipment, the user equipment uses the same temporary identifier in the coverage range of N base stations to be experienced in the process of processing the first service; wherein N is a positive integer greater than or equal to two.
Here, the user equipment may be a device with a mobile communication function, such as a mobile phone, a tablet computer, and the like.
The service access operation of the user equipment may be: when the user equipment needs to process the corresponding service, the initiated access process, or the access counting operation performed for responding to the request of the service initiating terminal;
for example, at least: sending an access pilot frequency sequence to a server; sending random access response information to the user equipment by the server; the user equipment randomly accesses the network based on the response information.
The allocating a temporary identifier to the user equipment based on the type of the user equipment includes: if the user equipment is first-class user equipment, allocating first-class temporary identifications to the user equipment; and if the user equipment is second-class user equipment, allocating second-class temporary identifications to the user equipment.
Different types of user equipment are distinguished in this embodiment: the first type of user equipment is small data or users moving infrequently; the second category of user equipment is big data, frequently moving users.
The consideration of the frequent movement may be a comprehensive consideration according to parameters such as connection duration, user movement rate, user movement direction, and site coverage, and may be calculated, for example, in the following manner: service duration user mobility rate/site diameter.
In this embodiment, the first service may be a service to be processed by a user equipment currently accessing to a base station.
Further, in this embodiment, determining the classification of the ue may also determine a type corresponding to the ue according to different carrier orientations, so as to determine different types of temporary identifiers corresponding to the ue; for example, the correspondence between the codes of the carriers and the types of the user equipments may be preset.
The example is simply performed: user identities can be divided into two broad categories: first, the first type temporary identifier is applicable to type 1) low mobility (mobility, which may consider relative mobility, such as mobility relative to site coverage, and the metric is: the number of sites traversed in unit time) or the service connection time is short (including users whose packet interval is greater than a threshold LTH in the service connection process, such services have enough time to perform reconfiguration behavior caused by handover, and the connection time of such user services can be set to be the length of a single packet), and such users are characterized in that in the service connection process, it is basically difficult to walk through one base station or the number of base stations with a certain set threshold, so that the corresponding user identifiers can be released or updated quickly and do not affect user experience, and the identifiers of such users can be allocated by using traditional site-based identifiers, thereby improving the reuse rate of the user identifiers;
secondly, the second type temporary identifier is suitable for the user identifier of the user type 2), and the user identifier is characterized in that the station-crossing movement is frequent, the service continuity is strong, the user identifier is not good due to frequent switching process and user identifier update, the user identifier available for a long time needs to be ensured, and the seamless experience of the service process can be realized.
In the embodiment, for the generation mode of the first-type temporary identifier, different base stations accessed to different base stations can be used for generating different C-RNTIs as the first-type temporary identifiers;
the generation manner for the second type temporary identifier may be an identifier generated by using an IMSI identifier or an IMSI, or an identifier reserved by the network, and is not bound to any base station.
In addition, the present embodiment also provides the following processing: if the user equipment is second type user equipment; acquiring the reusability of the second type temporary identifier; and determining N base stations which are suitable for the second type temporary identification distributed for the user equipment based on the reusability of the second type temporary identification.
The multiplexing degree is a value preset in the network equipment or a value obtained by calculation according to the selected parameters of the second type of user equipment. The parameters of the second type of user equipment may include a moving speed of the user equipment, a session duration of the user equipment, and the like.
In addition, regarding the selection of the user for calculating the multiplexing degree, the worst user equipment in the second class of user equipment can be selected for calculation; the worst user equipment may be the user equipment whose transmitted signal power is the lowest or whose received signal strength is the lowest.
The ideal reuse rate configuration is to make the user equipment not experience the cell during the moving process, 1) the cell allocates the same identification as the switched user for the user, and the requirement reuse rate > the number of cells crossed during the user session; 2) no collision will occur with users handed in from another cell.
For example, the multiplexing degree calculation method may employ: the integer is taken up [ (the session duration TTH + the user mobility rate MTH/the site radius +1) ] ^2 (1+ x), and the relevant requirements can be met. For a subscriber identity with high reusability, the highest service duration and subscriber mobility rate supported in the system are considered. x is the site overlap ratio, e.g., 20%. Describing mainly, a circle is drawn according to the current position of a user, the radius of the circle is the farthest distance which the user can reach during the service transmission period, and the radius of the circle is calculated; then calculating the area of the circle of each station; the number of small circles that this large circle may contain is counted as the reuse degree, because the user must not walk through this circle. Meanwhile, the user is not considered to be in the middle of the circle in the middle, so that +1 is added, and a circle is used as a protection generation, and the overlapping rate of the stations is also considered.
For the first type of user equipment, the probability of site switching is considered to be low, and the multiplexing degree of the first type of user equipment can be directly and simply set to be 1; or, for example, in the case that the service data packets are not very coherent, a single data packet may be directly set as the time length of the service connection, which is a short connection, and such a service may use a high multiplexing rate (the multiplexing rate is 1).
Or, based on the concept of multiplexing degree, multiplexing of user identification can be strengthened by further refining the grouping of users, specifically: if the user equipment is second type user equipment; determining a grouping of the user equipment, adjusting a degree of multiplexing for the user equipment based on the grouping; and determining N base stations applicable to the second type temporary identification allocated to the user equipment based on the reusability of the user equipment.
For example, according to the direction of the user, users in different beam directions can multiplex the same ID facing short IDs; on the other hand, according to the judgment of the moving direction of the user, the reuse degree N can be reduced because the calculation just like the calculation above considers that the user is the center, the moving distance is the radius to draw a circle, and the number of small circles in the circle, if only a certain direction is considered, only the number of small circles in a certain sector (a part of the circle) in the certain direction is considered, the reuse degree is reduced, and the reuse rate is improved.
Furthermore, the identification cost caused by completely no identification collision can be reduced by ensuring the identification collision with a certain probability. If two types of users exist in the same frequency band and adopt the same scrambling code, a dynamic user identification allocation method can be designed: firstly, ensuring that all identifiers are allocated into two categories, and when the second category of temporary identifiers is not enough, using a part of the first category of temporary identifiers, such as NTH identifiers or PTH percentage identifiers; once the type 1) identifiers are not enough, releasing part of identifiers borrowed by users with high reuse rate is preferably considered, and under the condition that resources with low reuse rate are still in shortage, informing adjacent sites to complete the synchronization of the newly added type 1) identifiers.
Therefore, by adopting the scheme, the type of the user equipment is determined according to the access operation of the user equipment, and at least two types of temporary identifications are distributed to the user equipment according to the type of the user equipment. In this way, different types of temporary identifications can be allocated according to the types of the user equipment, and the requirements of the development of the mobile communication technology can be met by using the different types of temporary identifications.
In addition, when the user equipment uses the second type temporary identifier, the same temporary identifier can be used when the same service is processed no matter the user equipment goes through several base stations. Therefore, the temporary identifier of the user equipment can be unbound with the base station, the user equipment is ensured to use the same temporary identifier in the same service processing process, the transparency of the user equipment is improved, the influence of switching operation on the user equipment is reduced, and the use experience of a user is improved.

In addition, when the user equipment uses the second type temporary identifier, the same temporary identifier can be used when the same service is processed no matter the user equipment goes through several base stations. Therefore, the temporary identifier of the user equipment can be unbound with the base station, the user equipment is ensured to use the same temporary identifier in the same service processing process, the transparency of the user equipment is improved, the influence of switching operation on the user equipment is reduced, and the use experience of a user is improved.
Example V,
An embodiment of the present invention provides a network device, as shown in fig. 4, including:
a classifying unit 41, configured to determine a type of a user equipment based on a service access operation of the user equipment;
an identifier allocating unit 42, configured to allocate a temporary identifier to the user equipment based on the type of the user equipment; the temporary identifier at least comprises a first type temporary identifier and a second type temporary identifier; when the first type temporary identification is distributed to the user equipment, the user equipment is enabled to use the temporary identification in the coverage range of one base station; when the second type temporary identifier is distributed to the user equipment, the user equipment uses the same temporary identifier in the coverage range of N base stations to be experienced in the process of processing the first service; wherein N is a positive integer greater than or equal to two.
Here, the user equipment may be a device with a mobile communication function, such as a mobile phone, a tablet computer, and the like.
The service access operation of the user equipment may be: when the user equipment needs to process the corresponding service, the initiated access process, or the access counting operation performed for responding to the request of the service initiating terminal;
for example, at least: sending an access pilot frequency sequence to a server; sending random access response information to the user equipment by the server; the user equipment randomly accesses the network based on the response information.
The classification unit is specifically configured to allocate a first-class temporary identifier to the user equipment if the user equipment is a first-class user equipment; and if the user equipment is second-class user equipment, allocating second-class temporary identifications to the user equipment.
Different types of user equipment are distinguished in this embodiment: the first type of user equipment is small data or users moving infrequently; the second category of user equipment is big data, frequently moving users.
The consideration of the frequent movement may be a comprehensive consideration according to parameters such as connection duration, user movement rate, user movement direction, and site coverage, and may be calculated, for example, in the following manner: service duration user mobility rate/site diameter.
In this embodiment, the first service may be a service to be processed by a user equipment currently accessing to a base station.
Preferably, the present embodiment provides another operation manner for determining the type of the user equipment:
the classification unit is specifically configured to extract user feature information from connection request information of a service access operation of the user equipment; judging whether the user characteristic information accords with a first preset condition, and if the user characteristic information accords with the first preset condition, determining that the user equipment is a first type of user equipment; otherwise, determining the user equipment as second type user equipment; the first preset condition is that the service type in the user characteristic information is a small data service type, or the moving speed in the user characteristic information is lower than a speed threshold.
For example, as shown in fig. 3, the user equipment transmits a preamble sequence by transmitting an msg1 message; the network equipment carries out random access response according to the received msg1 and sends msg2 information to the user equipment; the user equipment sends a connection request to the network equipment through the msg3 message, and can add fields capable of indicating mobility and service connection duration when requesting the service, or directly judge by the network itself; the network device assigns an appropriate temporary identifier based on the determination of the user device type at the time of the connection establishment feedback (Msg 4).
The method for determining the type of the user equipment can be that the mobility size M and the service connection duration T of the user equipment are expected, a preset or system broadcast mobility threshold MTH and a service connection duration threshold TTH are compared, when the M < MTH or the T < TTH, the type of the user equipment is determined to be the first type of user equipment, then an access pilot frequency sequence of the first preset type is selected, and otherwise, an access pilot frequency sequence of the second preset type is selected.
In addition, the classification of the user equipment described in this embodiment may be determined by whether the service to be processed is a large data service or a small data service, and the determination of the large data and the small data may be performed by using the service types: for example, the video is big data, the instant messaging chat is small data, and the determination can be performed by defining a certain service rate threshold, or setting a ratio according to the percentage of the service rate of other users of the current service rate station system. It will be appreciated that different data types may be served by different types of sites and that the site diameter references may be different.
Further, in this embodiment, determining the classification of the ue may also determine a type corresponding to the ue according to different carrier orientations, so as to determine different types of temporary identifiers corresponding to the ue; for example, the correspondence between the codes of the carriers and the types of the user equipments may be preset.
The example is simply performed: user identities can be divided into two broad categories: first, the first type temporary identifier is applicable to type 1) low mobility (mobility, which may consider relative mobility, such as mobility relative to site coverage, and the metric is: the number of sites traversed in unit time) or the service connection time is short (including users whose packet interval is greater than a threshold LTH in the service connection process, such services have enough time to perform reconfiguration behavior caused by handover, and the connection time of such user services can be set to be the length of a single packet), and such users are characterized in that in the service connection process, it is basically difficult to walk through one base station or the number of base stations with a certain set threshold, so that the corresponding user identifiers can be released or updated quickly and do not affect user experience, and the identifiers of such users can be allocated by using traditional site-based identifiers, thereby improving the reuse rate of the user identifiers;
secondly, the second type temporary identifier is suitable for the user identifier of the user type 2), and the user identifier is characterized in that the station-crossing movement is frequent, the service continuity is strong, the user identifier is not good due to frequent switching process and user identifier update, the user identifier available for a long time needs to be ensured, and the seamless experience of the service process can be realized.
In the embodiment, for the generation mode of the first-type temporary identifier, different base stations accessed to different base stations can be used for generating different C-RNTIs as the first-type temporary identifiers;
the generation manner for the second type temporary identifier may be an identifier generated by using an IMSI identifier or an IMSI, or an identifier reserved by the network, and is not bound to any base station.
Therefore, by adopting the scheme, the type of the user equipment is determined according to the access operation of the user equipment, and at least two types of temporary identifications are distributed to the user equipment according to the type of the user equipment. In this way, different types of temporary identifications can be allocated according to the types of the user equipment, and the requirements of the development of the mobile communication technology can be met by using the different types of temporary identifications.
In addition, when the user equipment uses the second type temporary identifier, the same temporary identifier can be used when the same service is processed no matter the user equipment goes through several base stations. Therefore, the temporary identifier of the user equipment can be unbound with the base station, the user equipment is ensured to use the same temporary identifier in the same service processing process, the transparency of the user equipment is improved, the influence of switching operation on the user equipment is reduced, and the use experience of a user is improved.
Example six,
An embodiment of the present invention provides a network device, as shown in fig. 4, including:
a classifying unit 41, configured to determine a type of a user equipment based on a service access operation of the user equipment;
an identifier allocating unit 42, configured to allocate a temporary identifier to the user equipment based on the type of the user equipment; the temporary identifier at least comprises a first type temporary identifier and a second type temporary identifier; when the first type temporary identification is distributed to the user equipment, the user equipment is enabled to use the temporary identification in the coverage range of one base station; when the second type temporary identifier is distributed to the user equipment, the user equipment uses the same temporary identifier in the coverage range of N base stations to be experienced in the process of processing the first service; wherein N is a positive integer greater than or equal to two.
Here, the user equipment may be a device with a mobile communication function, such as a mobile phone, a tablet computer, and the like.
The service access operation of the user equipment may be: when the user equipment needs to process the corresponding service, the initiated access process, or the access counting operation performed for responding to the request of the service initiating terminal;
for example, at least: sending an access pilot frequency sequence to a server; sending random access response information to the user equipment by the server; the user equipment randomly accesses the network based on the response information.
The allocating a temporary identifier to the user equipment based on the type of the user equipment includes: if the user equipment is first-class user equipment, allocating first-class temporary identifications to the user equipment; and if the user equipment is second-class user equipment, allocating second-class temporary identifications to the user equipment.
Different types of user equipment are distinguished in this embodiment: the first type of user equipment is small data or users moving infrequently; the second category of user equipment is big data, frequently moving users.
The consideration of the frequent movement may be a comprehensive consideration according to parameters such as connection duration, user movement rate, user movement direction, and site coverage, and may be calculated, for example, in the following manner: service duration user mobility rate/site diameter.
In this embodiment, the first service may be a service to be processed by a user equipment currently accessing to a base station.
Further, in this embodiment, determining the classification of the ue may also determine a type corresponding to the ue according to different carrier orientations, so as to determine different types of temporary identifiers corresponding to the ue; for example, the correspondence between the codes of the carriers and the types of the user equipments may be preset.
The example is simply performed: user identities can be divided into two broad categories: first, the first type temporary identifier is applicable to type 1) low mobility (mobility, which may consider relative mobility, such as mobility relative to site coverage, and the metric is: the number of sites traversed in unit time) or the service connection time is short (including users whose packet interval is greater than a threshold LTH in the service connection process, such services have enough time to perform reconfiguration behavior caused by handover, and the connection time of such user services can be set to be the length of a single packet), and such users are characterized in that in the service connection process, it is basically difficult to walk through one base station or the number of base stations with a certain set threshold, so that the corresponding user identifiers can be released or updated quickly and do not affect user experience, and the identifiers of such users can be allocated by using traditional site-based identifiers, thereby improving the reuse rate of the user identifiers;
secondly, the second type temporary identifier is suitable for the user identifier of the user type 2), and the user identifier is characterized in that the station-crossing movement is frequent, the service continuity is strong, the user identifier is not good due to frequent switching process and user identifier update, the user identifier available for a long time needs to be ensured, and the seamless experience of the service process can be realized.
In the embodiment, for the generation mode of the first-type temporary identifier, different base stations accessed to different base stations can be used for generating different C-RNTIs as the first-type temporary identifiers;
the generation manner for the second type temporary identifier may be an identifier generated by using an IMSI identifier or an IMSI, or an identifier reserved by the network, and is not bound to any base station.
In addition, the present embodiment also provides the following processing: the identifier allocation unit is specifically configured to, if the user equipment is a second type of user equipment; acquiring the reusability of the second type temporary identifier; and determining N base stations which are suitable for the second type temporary identification distributed for the user equipment based on the reusability of the second type temporary identification.
The ideal reuse rate configuration is to make the user equipment not experience the cell during the moving process, 1) the cell allocates the same identification as the switched user for the user, and the requirement reuse rate > the number of cells crossed during the user session; 2) no collision will occur with users handed in from another cell.
For example, for a user identifier with low reusability, the reusability calculation method may adopt: the integer is taken up [ (the session duration TTH + the user mobility rate MTH/the site radius +1) ] ^2 (1+ x), and the relevant requirements can be met. For a subscriber identity with high reusability, the highest service duration and subscriber mobility rate supported in the system are considered. x is the site overlap ratio, e.g., 20%. Describing mainly, a circle is drawn according to the current position of a user, the radius of the circle is the farthest distance which the user can reach during the service transmission period, and the radius of the circle is calculated; then calculating the area of the circle of each station; the number of small circles that this large circle may contain is counted as the reuse degree, because the user must not walk through this circle. Meanwhile, the user is not considered to be in the middle of the circle in the middle, so that +1 is added, and a circle is used as a protection generation, and the overlapping rate of the stations is also considered.
For the first type of user equipment, the probability of site switching is considered to be low, and the multiplexing degree of the first type of user equipment can be directly and simply set to be 1; or, for example, in the case that the service data packets are not very coherent, a single data packet may be directly set as the time length of the service connection, which is a short connection, and such a service may use a high multiplexing rate (the multiplexing rate is 1).
Or, based on the concept of multiplexing degree, multiplexing of user identifiers may be enhanced by further refining the grouping of users, where the identifier allocation unit is specifically configured to, if the user equipment is a second type of user equipment; determining a grouping of the user equipment, adjusting a degree of multiplexing for the user equipment based on the grouping; and determining N base stations applicable to the second type temporary identification allocated to the user equipment based on the reusability of the user equipment.
For example, according to the direction of the user, users in different beam directions can multiplex the same ID facing short IDs; on the other hand, according to the judgment of the moving direction of the user, the reuse degree N can be reduced because the calculation just like the calculation above considers that the user is the center, the moving distance is the radius to draw a circle, and the number of small circles in the circle, if only a certain direction is considered, only the number of small circles in a certain sector (a part of the circle) in the certain direction is considered, the reuse degree is reduced, and the reuse rate is improved.
Furthermore, the identification cost caused by completely no identification collision can be reduced by ensuring the identification collision with a certain probability. If two types of users exist in the same frequency band and adopt the same scrambling code, a dynamic user identification allocation method can be designed: firstly, ensuring that all identifiers are allocated into two categories, and when the second category of temporary identifiers is not enough, using a part of the first category of temporary identifiers, such as NTH identifiers or PTH percentage identifiers; once the type 1) identifiers are not enough, releasing part of identifiers borrowed by users with high reuse rate is preferably considered, and under the condition that resources with low reuse rate are still in shortage, informing adjacent sites to complete the synchronization of the newly added type 1) identifiers.
Therefore, by adopting the scheme, the type of the user equipment is determined according to the access operation of the user equipment, and at least two types of temporary identifications are distributed to the user equipment according to the type of the user equipment. In this way, different types of temporary identifications can be allocated according to the types of the user equipment, and the requirements of the development of the mobile communication technology can be met by using the different types of temporary identifications.
In addition, when the user equipment uses the second type temporary identifier, the same temporary identifier can be used when the same service is processed no matter the user equipment goes through several base stations. Therefore, the temporary identifier of the user equipment can be unbound with the base station, the user equipment is ensured to use the same temporary identifier in the same service processing process, the transparency of the user equipment is improved, the influence of switching operation on the user equipment is reduced, and the use experience of a user is improved.
