Description
Technical field
The present invention relates to the mobile communication technology field, particularly relate to a kind of MAC (Media AccessControl, media access control layer) method for message transmission and device.
Background technology
Growing along with wireless communication needs, it is crowded day by day that radio band becomes, in order better to improve the availability of frequency spectrum, and avoid phase mutual interference between the different system, to transmit some information mutually between the different system, that is to say, the A system sends its present employed band information of message informing B system to the B system, this class message is called intersystem communications message, certainly the intersystem communications message of this class also have a lot, as the notification message of the IP address of A system base-station, the positional information of A system base-station etc.
As shown in Figure 1, be the MAC message format that communication information adopted between prior art systems, this MAC message comprises the versatile MAC message header, load of MAC message and CRC (CyclicalRedundancy, CRC), wherein, the versatile MAC head is 48 bits, as shown in Figure 2, be the form of a kind of versatile MAC head of prior art, in this versatile MAC head, CID (connectionidentification) is a link identification, be used for the different logical links set up between distinguishing terminal and the entity, Type represents the type of MAC load.As shown in Figure 3, be the form of administrative messag MAC PDU, wherein, the type of 8 bits represents the MAC type of message.
In the current prior art, the transmission means of the payload of MAC message (load) has two kinds:
Mode one: pre-define each bit and be used for transmitting what message, receiving-transmitting sides is according to the pairing implication of each bit of predefined information acquisition, and this mode is called the mode of pre-defined bit attribute.For example, transmit up compossibility message SSRUF (Subscriber Station Uplink RadioFrequency, the user uplink wireless frequency), the content that may transmit comprises SSID (the ServiceSet Identifier of 48bit, the Service Area Identifier symbol), the BSID of 48 bits (Base Station Identity Code, base station identity code), the EIRP of 8 bits (Effective Isotropic Radiated Power, direction radiant power such as effectively), the RF SECTOR ID of 32 bits (radio-frequency antenna sign, Radio Frequency SectorIdentifier), the IP address, base station of the positional information of 32 bits and 128 bits (IPv6) or 32 bits (IPv4), add the MAC head of 48 bits, the CRC of 32 bits, the management message type of 8 bits, adopt the mode of pre-defined bit attribute, the transformat of SSURF message as shown in Figure 4.
The inventor finds that there is following problem in mode one: the intrasystem MAC message format of the MAC message reference between system, therefore in MAC message, can there be a lot of otiose information, as the intrasystem base station of CID of in versatile MAC message header (shown in Figure 2), being transmitted and the LLID between the terminal, for intersystem communications, this message is exactly useless, belongs to invalid redundant information.Another shortcoming of this mode is, owing to need pre-define the represented implication of all bits, in order to support the versatility of message, may comprise a lot of unnecessary communication informations, for example,, then do not need to transmit the RF SECTOR ID of 32 bits for the terminal of single antenna in above-mentioned SSURF message, for the terminal that moves, also can be without transmission of location information.The transmission of these redundant informations has reduced information transfer efficiency, has wasted interface-free resources.
Mode two: the transformat that intersystem communications MAC message adopts also comprises parts such as above-mentioned versatile MAC message header, MAC load and CRC, at MAC load message part, also be to constitute (Fig. 3) by type and payload, but each IE (the Information Element among this mode payload, information unit), adopt TLV (Type-Length-Value, type-length-value, a kind of form) coded system transmission, so-called TLV, be meant each IE, all transmit type T, length L and the value V of this IE.The opposite end communication entity that receives is by identification T, and the type of coming definite IE that is transmitted by length L, obtains the length of message, reads the value of the value of corresponding message-length as this message afterwards.Be example to transmit up compossibility message SSURF transmission of messages as shown in Figure 5, adopt the mode of TLV, only transmit SSID in the SSURF message and the transformat of BSID.
The inventor finds that there is following problem in mode two: this mode also adopts the versatile MAC message header, has therefore also carried as some otiose message such as CID, has reduced information transfer efficiency, has wasted interface-free resources.Though this mode can selectively be transmitted necessary information, for each IE, all needs transport-type T (Type), length L (Length) and value V (Value), redundant information is more, has reduced transmission of Information efficient, has wasted interface-free resources.
