[0172] The present document will be elaborated below with embodiments of specific application scenarios.

Embodiment 1

[0173] An example of a notification flow of a temporary authorization change of a ProSe, as shown in FIG. 5, includes the following steps.

[0174] In Step 301, due to an authorization change of a ProSe, a visited network or a local network triggers reauthorization of the ProSe, and the visited network or the local network initiates a service policy change notice to a home network of UE, herein the authorization change may be temporary.

[0175] Here, the service policy change notice message may be initiated for a specific UE, may also be initiated for all UEs in a PLMN, the former is required to carry IMSI information of the UE, and the latter is required to indicate a PLMN of which UE is required to be reauthorized, i.e. a HPLMN ID of the home network of the UE.

[0176] Here, the service policy change notice message further carries an ID of a PLMN receiving a policy change, i.e. the PLMN initiating reauthorization, and service policy changes, for example, a communication and/or discovery process requires reauthorization.

[0177] Here, the service policy change notice message may further carry an authorization update type, and an update time limitation indication specifically indicates the home network authorization update type, i.e. whether the authorization change is a permanent update or a temporary update.

[0178] In case of a temporary update, time information for temporary forbidding may further be provided. The time information may be absolute time, and may also be relative time.

[0179] The above update time limitation indication may be implemented by adding a new IE, or may be implemented in an implicit manner. For example, if the time information is not carried, it is a permanent update, and if the time information is carried, it is identified that the update is valid within a time period represented by the time information.

[0180] The service policy change notice message may further carry an authorization type, for example, any one of a full authorization, a conditional authorization and no authorization.

[0181] In Step 302, after receiving the service policy change notice, a ProSe server of the home network initiates a notice to the affected UE or notifies the UE of the service change when the UE initiates a service authorization request next time.

[0182] Here, if the IMSI is not carried in Step 301, the ProSe server may be required to send multiple messages to the related UE. Here, a manner for notifying the UE may be directly notifying the UE of a specific content of the updated authorization change, or only notifying the UE of authorization updating to trigger the UE to reinitiate an authorization request process to obtain the specific updated content, that is, Steps 303˜306 are executed.

[0183] Here, if the authorization update type and/or the time information and/or the authorization type are carried in Step 301, the ProSe server of the home network may notify the UE of the above information.

[0184] Or, the above information is not sent, and the UE is only notified that it is necessary to initiate reauthorization of the ProSe and acquire updated authorization information in subsequent Steps 303˜306. In order to reduce message interaction, a direct notification manner (that is, Steps 303˜306 are not executed) is recommended under a condition that access is forbidden. For a conditional authorization, a manner of notifying the UE to reacquire the authorization information (that is, Steps 303˜306 are executed) may be selected.

[0185] In Steps 303˜306, after receiving a reauthorization notice, the UE reinitiates a service authorization request to a ProSe server of the visited network, and the ProSe server of the visited network or the local network sends the authorization request to the ProSe server of the home network. The ProSe server of the home network returns an authorization request response carrying updated authorization information of the UE to the ProSe server of the visited network or the local network. The ProSe server of the visited network or the local network returns a final service authorization response carrying the updated authorization update type and/or time information and/or authorization type in Step 301 to the UE according to a local policy.

[0186] In Steps 307˜308, the ProSe server of the home network sends updated service policy data carrying changed ProSe service data to an HSS. Here, if the IMSI is carried in Step 301, the IMSI is required to be carried in Step 307. If the IMSI is not carried, the ProSe server of the home network may check the affected UE and send multiple messages to the HSS for the affected UE. Or the ProSe server of the home network sends only one message carrying the changed PLMN identification, and the HSS checks the affected UE in Step 309.

[0187] Here, if the authorization update type and the time information are carried in Step 301, the ProSe of the home network may judge whether it is necessary to notify the HSS according to locally configured policy information. For example, temporary authorization withdrawing may not be notified to the HSS, or the authorization update type and the time information are carried in the message for notifying the HSS in Step 307. The message may further carry the authorization type, for example, one of a full authorization, a conditional authorization and no authorization.

[0188] If the message does not carry the IMSI, the HSS is required to judge the UE which may be affected according to the ID of the PLMN requiring reauthorization, and update its subscription data.

[0189] In Steps 309˜310, for the affected UE, the HSS may judge to reinsert user data into a MME where the UE is registered according to a registration state of the UE. The MME judges a policy change type, and if a broadcast policy of the UE changes and an 51 bearer is created for the UE, the MME is required to notify that authorization information of the ProSe changes through a user context modification message.

[0190] If the authorization update type and the time information are carried in Step 307, the authorization update type and the time information may also be included in the subscription data inserted by the HSS.

Embodiment 2

[0191] An example of a second notification flow of an authorization change of a ProSe, as shown in FIG. 6, includes the following steps.

[0192] In Step 401, due to an authorization change of a ProSe, a visited network or a local network triggers reauthorization of the ProSe, and the visited network or the local network initiates a service policy change notice to a home network of UE, herein the authorization change may be temporary.

[0193] Here, the service policy change notice message may be initiated for a specific UE, may also be initiated for all UEs in a PLMN, the former is required to carry IMSI information of the UE, and the latter is required to indicate a PLMN of which UE is required to be reauthorized, i.e. a HPLMN ID of the home network of the UE.

[0194] Here, the service policy change notice further carries an ID of a PLMN receiving a policy change, i.e. the PLMN initiating reauthorization, and service policy changes, for example, a communication and/or discovery process requires reauthorization.

[0195] Here, the service policy change notice message may further carry an authorization update type, and an update time limitation indication specifically indicates the home network authorization update type, i.e. whether the authorization change is a permanent update or a temporary update.

[0196] In case of a temporary update, time information for temporary forbidding may further be provided. The time information may be absolute time, and may also be relative time.

[0197] The above update time limitation indication may be implemented by adding a new IE, or may be implemented in an implicit manner. For example, if the time information is not carried, it is a permanent update, and if the time information is carried, it is identified that the update is valid within a time period represented by the time information.

[0198] The service policy change notice message may further carry an authorization type, for example, any one of a full authorization, a conditional authorization and no authorization.

[0199] In Step 402, after receiving the service policy change notice, a ProSe server of the home network initiates a notice to the affected UE or notifies the UE of the service change when the UE initiates a service authorization request next time.

[0200] Here, if the IMSI is not carried in Step 401, the ProSe server may be required to send multiple messages to the related UE.

[0201] Here, a manner for notifying the UE may be directly notifying the UE of a specific content of the updated authorization change, or only notifying the UE of authorization updating to trigger the UE to reinitiate an authorization request process to obtain the specific updated content, that is, Steps 403˜406 are executed.

[0202] Here, if the authorization update type and/or the time information and/or the authorization type are carried in Step 401, the ProSe server of the home network may notify the UE of the above information.

[0203] Or, the above information is not sent, and the UE is only notified that it is necessary to initiate reauthorization of the ProSe and acquire updated authorization information in subsequent Steps 403˜406. In order to reduce message interaction, a direct notification manner (that is, Steps 403˜406 are not executed) is recommended under a condition that access is forbidden. For a conditional authorization, a manner of notifying the UE to reacquire the authorization information (that is, Steps 403˜406 are executed) may be selected.

[0204] In Steps 403˜406, after receiving a reauthorization notice, the UE reinitiates a service authorization request to the ProSe server of the home network. Optionally, the ProSe server of the home network sends the authorization request to the ProSe server of the visited network or the local network, and the ProSe server of the visited network or the local network returns an authorization request response carrying updated authorization information of the UE to the

[0205] ProSe server of the home network. Since the home network has acquired the latest information in Step 401, so that Steps 404˜405 are optional. The ProSe server of the home network returns a final service authorization response carrying the updated authorization update type and/or time information and/or authorization type in Step 401 to the UE according to a local policy.

[0206] In Steps 407˜408, the ProSe server of the home network sends updated service policy data carrying changed ProSe service data to an HSS.

[0207] Here, if the IMSI is carried in Step 401, the IMSI is required to be carried in Step 407. If the IMSI is not carried, the ProSe server of the home network may check the affected UE and send multiple messages to the HSS for the affected UE. Or the ProSe server of the home network sends only one message carrying the changed PLMN identification, and the HSS checks the affected UE in Step 409.

[0208] Here, if the authorization update type and the time information are carried in Step 401, the ProSe of the home network may judge whether it is necessary to notify the HSS according to locally configured policy information. For example, temporary authorization withdrawing may not be notified to the HSS, or the authorization update type and the time information are carried in the message for notifying the HSS in Step 407. The message may further carry the authorization type, for example, one of a full authorization, a conditional authorization and no authorization.

[0209] If the message does not carry the IMSI, the HSS is required to judge the UE which may be affected according to the ID of the PLMN requiring reauthorization, and update its subscription data.

[0210] In Steps 409˜410, for the affected UE, the HSS may judge to reinsert user data into an MME where the UE is registered according to a registration state of the UE. The MME judges a policy change type, and if a broadcast policy of the UE changes and an 51 bearer is created for the UE, the MME is required to notify that authorization information of the ProSe changes through a user context modification message.

[0211] If the authorization update type and the time information are carried in Step 407, the authorization update type and the time information may also be included in the subscription data inserted by the HSS.

Embodiment 3

[0212] An example of addition of time limitation information of an authorization into subscription data of a ProSe, as shown in FIG. 7, includes the following steps.

[0213] In Step 501, a ProSe server of a home network may be triggered to acquire subscription data from an HSS in a process of requesting for a service authorization or requesting for a service (broadcast and monitoring) and the like by UE.

[0214] In Steps 502˜503, the acquired subscription data may include time limitation information of an authorization for some service (i.e. communication and/or discovery) corresponding to a PLMN, and the time may be absolute time, and may also be relative time.

[0215] When finding that an authorization time limitation of certain UE is exceeded, the ProSe server of the home network may notify the related UE.

[0216] In Step 504, a MME may be triggered to acquire the subscription data from the HSS in an attachment or location updating process by the UE.

[0217] In Steps 505˜506, the MME initiates a location updating request to the HSS to acquire the subscription data, and the HSS returns a location updating response carrying the subscription data of a user, which may include the time limitation information of the authorization for some service (such as communication and/or discovery), herein the time may be absolute time, and may also be relative time.

[0218] If an authorization time limitation of a broadcast policy of the UE is exceeded, for example, permission is changed into forbidding after a certain time and an S1 bearer is created for the UE, the MME may notify that authorization information of the ProSe changes through a user context modification message, and withdraw a response resource.

[0219] With addition of the time limitation information into the subscription data, when the time limitation information changes, the HSS is required to notify the ProSe server of the home network and the MME through the updated subscription data. If the authorization is timed out and the S1 bearer is created for the UE, the MME is required to notify that the authorization information of the ProSe changes through the user context modification message.

[0220] If being implemented in form of software function module and sold or used as an independent product, the integrated module in the embodiment of the present document may also be stored in a computer-readable storage medium. Based on such an understanding, the technical solution of the embodiment of the present document substantially or a part with contributions to the conventional art may be embodied in form of software product, and the computer software product is stored in a storage medium, including a plurality of instructions arranged to enable a computer (which may be a personal computer, a server, network device or the like) to execute all or part of the method in each embodiment of the present document. The preceding storage medium includes: various media capable of storing program codes such as a U disk, a mobile hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk or a compact disc. Therefore, the embodiment of the present document is not limited to any specific hardware and software combination.

[0221] Correspondingly, the embodiment of the present document further provides a computer storage medium, in which a computer program is stored, the computer program is arranged to execute a method for processing an authorization change of a ProSe in the embodiment of the present document.

[0222] The above is only the preferred embodiment of the present document and not intended to limit the scope of protection of the present document.

INDUSTRAIL APPLICABILITY

[0223] According to the method for processing the authorization change of the ProSe in the embodiment of the present document, the method includes that: the ProSe server of the visited network or the local network triggers reauthorization of the ProSe; and the ProSe server of the visited network or the local network sends the updated authorization information to the ProSe server of the home network, the updated authorization information includes the update time limitation indication, and/or the time information, and/or the authorization type. By the embodiment of the present document, processing is implemented without the HSS, so that the problem that a load of a network element such as the HSS is increased by impact of the authorization change of the ProSe on the network element such as the HSS is solved.
