A system architecture of a Public Land Mobile Network (PLMN) access mode may be shown in
A system architecture of a Neutral Host Network (NHN) access mode may be shown in
A network in the NHN access mode indicates different participating service providers through Participating Service Provider Identities (PSP-IDs) broadcasted in a System Information Block (SIB). A MF network in the NHN access mode supports multiple PSP-IDs, so as to support multiple service providers to share the MF network for providing services. Due to limitation of a size of the System Information Block, only a finite quantity of PSP-IDs may be broadcasted. For example, at most 31 PSP-IDs may be broadcasted in a System Information Block of the MulteFire (SIB_MF, also called as eSIB), and the PSP-IDs may also include different types of PSP-IDs. The different types of PSP-IDs are mainly indicated by a type indication carried in each of the PSP-IDs at present. For example, each of the PSP-IDs includes a 24-bit ID and a 2-bit type indication. Since each of the PSP-IDs carries one type indication, overheads for indicating the types of the PSP-IDs are overlarge.
In addition, some embodiments of the present disclosure may be applied to mobile communication technologies including, but not limited to, a Code Division Multiple Access 2000 (CDMA2000), a Wideband CDMA (WCDMA), a Time Division-Synchronous CDMA (TD-SCDMA), a Worldwide Interoperability for Microwave Access (WiMAX), a LTE/LTE-A, the LAA, the MulteFire, and fifth, sixth and N-th generations mobile communication technologies which may appear subsequently.

Referring to
S301: generating a system message by an access device, wherein the system message may include multiple participating service provider identities (PSP-IDs), PSP-IDs of a same type among the multiple PSP-IDs are sequentially arranged, and different types of PSP-IDs among the multiple PSP-IDs are arranged according to a preset sequential order; and the system message further includes indication information for each type of PSP-IDs, and the indication information is used for indicating a location of each type of PSP-IDs.
S302: transmitting the system message by the access device.
In some embodiments of the present disclosure, the system message includes, but not limited to, the SIB_MF system message. The system message may also be other system messages, such as a SIBX system message, wherein X is a natural number, such as 1, 2, 3, 4 and so on.
In some embodiments of the present disclosure, because the PSP-IDs of the same type among the multiple PSP-IDs are arranged sequentially and different types of PSP-IDs are arranged according to the preset sequential order, so that a location of each type of PSP-IDs may be identified by the indication information, and each type PSP-IDs may be identified, i.e.,—a type of each of the multiple PSP-IDs is identified.
Optionally, the indication information may be used for identifying the location of each type of PSP-IDs through indicating one or more of a length, a location and a boundary of the type of PSP-IDs. For example, the location of each type of PSP-IDs may be acquired through indicating the length in combination with an arrangement order of all types. If the multiple PSP-IDs include a first type of PSP-IDs, a second type of PSP-IDs and a third type of PSP-IDs, and the first type of PSP-IDs, the second type of PSP-IDs and the third type of PSP-IDs are arranged in order, then in case that the length of each of the types is known, locations of various types of PSP-IDs may be determined, and thus the type of each PSP-ID is acquired. For example, the location of each type of PSP-IDs may be determined through indicating the location, and thereby the type of each PSP-ID is acquired. For example, the location of each type of PSP-IDs may be acquired through indicating the boundary in combination with the arrangement order of all types; if the multiple PSP-IDs include the first type of PSP-IDs, the second type of PSP-IDs, and the third type of PSP-IDs, and the the first type of PSP-IDs, the second type of PSP-IDs, and the third type of PSP-IDs are arranged in the order, then in case that the boundary of each type of PSP-IDs is known, the locations of the various types of the PSP-IDs may be determined, and thus the type of each PSP-ID is acquired.
Optionally, the indication information may include information for indicating start and end locations of each type of PSP-IDs among the multiple PSP-IDs; or the indication information may include information for indicating end locations of a first type of PSP-IDs to a last but one type of PSP-IDs arranged according to the preset sequential order among the multiple PSP-IDs; or the indication information may include information for indicating start locations of a second type of PSP-IDs to a last type of PSP-IDs arranged according to the preset sequential order among the multiple PSP-IDs.
For example, the SIB_MF supports 0-31 PSP-IDs and each of the PSP-IDs includes 24 bits, and a case in which there are three types of PSP-IDs is assumed, and the three types are represented by a first type, a second type and a third type, respectively. The abovementioned preset sequential order may be that an order of the three types of PSP-IDs in the SIB_MF is the first type, the second type and the third type in sequence, such as a PLMN PSP, an OID PSP and a hash PSP. Therefore, the indication information may include indication information of the start and end locations of each type of PSP-IDs. For example, as shown in
Certainly, in order to save bit overheads, adjacent types in the system message are arranged successively, that is to say, the end location of a previous type and the end location of a next type may be indicated once. Meanwhile, the start and end locations of an entirey of all PSP-IDs may be acquired through a coding result of a Radio Resource Control (RRC), and thus do not need to be indicated. Taking the SIB_MF for example, supposing that three types of PSP-IDs are supported, namely a first type, a second type and a third type which are successively arranged in the order. In such a case, the end location of the first type or the start location of the second type may be indicated through 5 bits, and the end location of the second type or the start location of the third type may be indicated through another 5 bits. The end location or the start location may be equivalent to a boundary between different ones of the types. For example, as shown in
An example of indicating PSP-IDs in a RRC signaling is shown by following codes, wherein a maximum number of PSP-IDs is 31 (maxPSP-SIB-MF=31, PSP-IdentityInfo is 24 bits):
Optionally, the indication information may be used for jointly indicating the end locations of the first type to the last but one type arranged according to the preset sequential order among the multiple PSP-IDs; or the indication information may be used for jointly indicating the startlocations of the second type to the last type arranged according to the preset sequential order among the multiple PSP-IDs.
In some embodiments, since different types of PSP-IDs may be successively arranged in the order, dependency between two adjacent types may be simplified. Taking the three types of PSP-IDs for example, when the end location of the first type is K, the end location of the second type 2 probably is K to a maximum N, and the locations of the third type do not need to be additionally indicated by bits. Taking the SIB_MF maximally supporting 31 PSP-IDs for example, the start location of the first type is specified to be 0, the end location of the first type may have 32 possibilities, i.e., from 0 to 31, and the start location of the second type is determined by the end location of the first type. Thus, the end location of the second type may have 32 possibilities to zero possibility corresponding to the end location of the first type from 0 to 31, repectively, and formed into an arithmetic progression, i.e., totally have 512 possibilities (namely (32+0)*32/2), and the start and end locations of the types in different cases may be indicated through 9 bits. Therefore, the end locations of the first type to the last but one type arranged according to the preset sequential order among the multiple PSP-IDs may be jointly indicated; or the start locations of the second type to the last type arranged according to the preset sequential order among the multiple PSP-IDs may be jointly indicated, so as to save the overheads.
The example of indicating the PSP-IDs in the RRC signaling is shown by following codes, wherein the maximum number of the PSP-IDs is 31 (PSP-SIB-MF=31):
Optionally, when the system message includes at least one PSP-ID list, the PSP-IDs of the same type among PSP-IDs included in each of the at least one PSP-ID list are sequentially arranged, different types of PSP-IDs among the PSP-IDs included in each of the at least one PSP-ID list are arranged according to the preset sequential order, and each of the at least one PSP-ID list further includes the indication information of each type of PSP-IDs. The indication information is used for indicating a location of each type of PSP-IDs.
Some embodiments may be achieved through combining with the abovementioned embodiments. That is to say, the indication information included in each PSP-ID list may be any indication information introduced in the abovementioned embodiments.
In addition, it should be noted that a case in which the system message includes the at least one PSP-ID list is optional, that is to say, in some embodiments of the present disclosure, the system message may not include the at least one PSP-ID list.
Optionally, when the system message includes the at least one PSP-ID list, the PSP-IDs of the same type among the multiple PSP-IDs correspond to the same one of the at least one PSP-ID list, and the at least one PSP-ID list is arranged according to a preset sequential order, and the indication information is used for indicating the location of each of the at least one PSP-ID list.
In some embodiments, the PSP-IDs of the same type may be placed into the same PSP-ID list. The at least one PSP-ID list is arranged according to a preset sequential order, so that the type of each PSP-ID may be determined simply through identifying the location of each of the at least one PSP-ID list according to the indication information, and the overheads may be saved. For example, in some embodiments, the codes may be shown below:
Optionally, in order to meet a limitation of a maximum number of transmitted PSP-IDs in the system message, a sum of amounts of PSP-IDs in all types may be limited to be less than or equal to the maximum number being allowed. Taking the SIB_MF maximally supporting 31 PSP-IDs for example, it needs to specify that the sum of the amounts of PSP-IDs in the the three types is less than or equal to 31, which may be shown as follows by way of the RRC message:
Optionally, when the system message includes the at least one PSP-ID list, the PSP-IDs of the same type among the multiple PSP-IDs correspond to the same PSP-ID list, and the at least one PSP-ID list is arranged according to the preset sequential order, the indication information is used for indicating whether each of the at least one PSP-ID list corresponding to the preset sequential order appears or not.
For example, when the abovementioned preset sequential order corresponds to the the first type, the second type and the third type, the indication information may indicate whether lists corresponding to the first type, the second type and the type 3 appear or not. Since the order is known, for example the order takes a sequence of the first type, the second type and the third type, when all of the three types appear, the type of the PSP-IDs in the first list may be determined to be the first type, the type of the PSP-IDs in the second list may be determined to he the second type, and the type of the PSP-IDs in the third list may be determined to he the third type. For example, in some embodiments, the codes may be shown below:
Optionally, in sonic embodiments, the amount of PSP-IDs included in the at least one PSP-ID list is less than or equal to a specified maximum number. Therefore, the amount of the PSP-IDs may be limited.
In sonic embodiments of the present disclosure, an access device generates the system message, the system message includes multiple PSP-IDs, PSP-IDs of the same type among the multiple PSP-IDs are sequentially arranged, and different types of PSP-IDs are arranged according to the preset sequential order, and the system message further includes indication information of each type of PSP-IDs, and the indication information is used for indicating the location of each type of PSP-IDs; and the access device trasnsmits the system message. Compared with related art in which each PSP-ID needs to carry type indication information, some embodiments of the present disclosure may reduce the overheads for indicating the type of a PSP-ID.
