In order to help to describe the present invention, parameter name, value, length and other features of some demonstration is used to describe channel, message and fixing or the variable identifier of communicating by letter between mobile radio station and the base station.Should be noted that above-mentioned parameter name only is for illustrative purposes, and can use other title to go to describe identical or similar function.

According to one embodiment of present invention, a kind of method that produces PLCM based on ESN is called as PLCM_37_ESN.In addition, a kind ofly be called as PLCM_37_BS based on for example offering the method that minimum effective 32 bits of this portable terminal produce minimum effective 37 bits of PLCM by base station (BS).

Use the term that is applicable to the PLCM that comprises 37 bits of above definition to illustrate one or more embodiment of the present invention.It should be noted that above-mentioned example embodiment should not be interpreted as limiting the range of application of disclosed specific embodiment.PLCM structure based on different can realize alternative embodiment.For example, in one embodiment, this PLCM can comprise 39 bits, and therefore is defined as for example PLCM_39.

With reference to figure 5 and 6, when the base station assigns Traffic Channel was given portable terminal, the public long code type was transmitted in this base station on ECAM, for example the value of 32 bits (for example, PLCM_32), to notify this portable terminal how to produce these minimum effective 37 bits (for example, M36～M32 and M31～M0).When this PLCM type or PLCM_TYPE were " 1 ", this base station provided this PLCM_32 on this ECAM.Similarly, the value of this 32 bit of this base station assigns, and this portable terminal uses it to produce PLCM.

In one embodiment, when PLCM type PLCM_TYPE is when receiving from the base station via this ECAM, determine whether that this PLCM_TYPE value is " 1 ".If like this, then this portable terminal uses this PLCM_32 value of this base station forwarding to produce for example minimum effective 32 bit M31～M0 of the PLCM of this portable terminal.If this PLCM type PLCM_TYPE is " 0 ", this terminal is used the version of permutatation of the ESN of this portable terminal, with minimum effective 37 bits that for example produce PLCM (for example, M36～M0).

In certain embodiments, portable terminal can move to second sub-district from first sub-district, and a PLCM distribution method (for example, the PLCM_32 of base station assigns) is used in this first sub-district here, and the 2nd PLCM distribution method (for example, the ESN of permutatation) is used in second sub-district.According to realization, can use such as the value of " 0 " or " 1 " and represent PLCM distribution method in the sub-district.In having the data structure of a plurality of fields, transmit this value.This data structure is sent to portable terminal from this base station, with the variation of notice portable terminal at the PLCM production method.

Can transmit this data structure through professional connection message (SCM) or general switch indicating information (UHDM).Field in this data structure, can be set to first value such as PLCM_TYPE or USE_ESN_BASED_PLCM, such as " 1 " (if USE_ESN_BASED_PLCM=" 0 "), to be used to be provided with the Long Code Mask of portable terminal with the value (for example, PLCM_32, PLCM_37, PLCM_39) of expression base station assigns.If field PLCM_TYPE is set to null value, calculate this Long Code Mask based on the ESN that for example rearranges so.

If this ESN that rearranges can cause the Long Code Mask value that may conflict with another portable terminal in the sub-district, this base station will be distributed such as the value of PLCM_32 and give this terminal so, make this terminal for example can produce minimum effective 37 bits of this PLCM (M36～M0).

In the preferred embodiment, based on the value of field USE_ESN_BASED_PLCM, the base station can notify mobile radio station that the method that produces PLCM based on ESN is converted to method based on the value of base station assigns, and this base station can oneself be changed.This business connection message (SCM) or general switch indicating information (UHDM) can be used for this field value is delivered to portable terminal from the base station.

For example, when using the ESN of this permutatation, the value of this USE_ESN_BASED_PLCM field is set to " 1 ".With reference to figure 8, for example, this base station should for example be converted to the PLCM_32_BS method from PLCM_32_ESN be set to " 0 " of professional connection message (SCM) or general switch indicating information (UHDM) with the method for notifying this terminal to produce this PLCM.

With reference to figure 9, except field PLCM_32, this base station has also increased field PLCM_INCL.According to a preferred embodiment of the invention, PLCM_INCL also can be in this ECAM.PLCM_INCL can be set to notify this portable terminal whether to comprise new field PLCM_39 this message of transmitting from this base station.This message can be for example professional connection message (SCM) or general switch indicating information (UHDM), EACM or on professional, control or overhead channel from the base station or other network componentses send any other message of this portable terminal to.

Preferably, when the value of this field PLCM_INCL was set to " 0 ", this new field PLCM_32 was omitted.When if the value of this field PLCM_INCL is set to " 1 ", for example, this new field PLCM_32 is included in this message.Therefore, PLCM_INCL preferably includes 1 bit.

With reference to figure 7, in one embodiment, (M36～M0) can be divided into the first minimum effective 5 bits (M36～M32) and second minimum effective 32 bits (M31～M0) to minimum effective 37 bits of this PLCM.If the field USE_ESN_BASED_PLCM in professional connection message (SCM) or general switch indicating information (UHDM) or ECAM is set to " 0 ", then this terminal with first minimum effective 5 bits of this PLCM (M36～M32) be set to " 11011 ", and with second minimum effective 32 bits (M31～M0) is set to equal minimum effective 32 bit PLCM_32.

If such as the field USE_ESN_BASED_PLCM in the message of professional connection message (SCM) or general switch indicating information (UHDM), ECAM, for example, be set to " 1 ", then this terminal is with first minimum effective 5 bits (M36～M32) be set to " 11000 ", and produce second minimum effective 32 bits (M31～M0) based on the ESN of this permutatation.

Get back to and consult Fig. 9, according to an aspect of the present invention, if the value of field USE_ESN_BASED_PLCM is set to " 0 ", and the value of field PLCM_INCL is " 1 ", so field PLCM_39 is increased to the message that is transmitted to this portable terminal from this base station.But if the value of this field USE_ESN_BASED_PLCM is set to " 1 ", perhaps this field PLCM_INCL is set to " 0 ", and this field PLCM_39 is omitted.

Therefore, when needing the PLCM scheme of BS distribution, the present invention is increased on the message (for example, SCM or UHDM or ECAM) one among new field PLCM_INCL and PLCM_32, PLCM_37 or the PLCM_39.When this terminal was switched from the base station of a support ESN_PLCM allocative decision, this method allowed this portable terminal to constitute PLCM based on the value that is provided by new base station.

Therefore, in example embodiment, in this SCM, USE_ESN_BASED_PLCM is removed, and increases a bit PLCM_TYPE_INCL and replace.When PLCM_TYPE_INCL is set to " 1 ", then comprise 4 bit PLCM_TYPE.During this service negotiation, when not changing among this PLCM_TYPE, PLCM_TYPE_INCL is set to " 0 ".When PLCM_TYPE is set to " 0001 ", can comprise for example 39 bit PLCM_39.

In another embodiment, when PLCM_TYPE_INCLr equaled " 1 ", this mobile radio station PLCM_TYPEs was set to PLCM_TYPEr.When PLCM_TYPEr was comprised and equal " 0001 ", this mobile radio station PLCM_39s was set to PLCM_39r, as to be provided in the professional connection message structure of demonstrating below:

PLCM_TYPE_INCL	1
PLCM_TYPE_INCL	1	PLCM_TYPE	0 or 4
PLCM_39	0 or 39	PLCM_TYPE	0 or 4

In the embodiment of this demonstration, PLCM_TYPE_INCL is the designator that comprises this PLCM type.If the base station comprises PLCM_TYPE in message, then this field of this base station is set to " 1 ", otherwise this field of this base station is set to " 0 ".

PLCM_TYPE is the PLCM type indicator.If PLCM_TYPE_INCL is set to " 0 ", this field is omitted in the base station, otherwise the base station comprises this field, and this field is set to as following corresponding PLCM type.

For example, when mobile radio station be not in the time of (that is, the MCC of this mobile radio station is different from the MCC of this base station), not use PLCM_TYPE " 0010 " in its this country.When this mobile radio station is not in the time of (that is, the MCC of this mobile radio station or MNC are different from the MCC or the MNC of this base station), not use PLCM_TYPE " 0011 " at its local network.

In one embodiment, PLCM_39 represents 39 minimum effective bits of this PLCM.If PLCM_TYPE is not set to " 0001 ", then this field is omitted in the base station, otherwise the base station comprises this field, and it is set to for example 39 minimum effective bits of this PLCM.

According to the above and with reference to Figure 10, when this PLCM type (PLCM_TYPE) was " 0001 ", the form of PLCM comprised the PLCM_40 that for example constitutes with 40 bits.(perhaps the highest significant bit (M39) is set to " 1 " to portable terminal among the M39～M0), and (M38～M0) is assigned as 39 bits (PLCM_39) by base station assigns will to be lower than 39 bits of this highest significant bit (M39) with PLCM_40.

Figure 11 is the schematic diagram according to an embodiment PLCM form, represents that wherein the field (USE_ESN_BASED_PLCM) of the user mode of the second type PLCM (USE_ESN_BASED_PLCM) is " 0 ".With reference to Figure 11, for example, " 10 " are used as the highest effective two bit M41 and M40, and " 1 " is used as the bit M39 that is close to the highest effective two bit M41 and M40, and are used as 39 lower bit M38 to M0 respectively by " 39 bit PLCM_39 " of base station assigns.

Figure 12 is the schematic diagram according to an embodiment PLCM form, represents that wherein the field (USE_ESN_BASED_PLCM) of the user mode of the second type PLCM (USE_ESN_BASED_PLCM) is " 1 ".With reference to Figure 12, for example, " 11 " are used as the highest effective two bit M41 and M40, " 000 " is used as three bit M39 to M37 of the highest effective two bit M41 of next-door neighbour and M40, " 11000 " are used as five bit M36 to M32 that are close to these three bit M39 to M37, and the Electronic Serial Number Permuted_ESN of permutatation is used as remaining 32 lower bit M31 to M0.

Figure 13 is the schematic diagram of field according to one embodiment of present invention, and this field will be added to professional connection message (SCM) or general switch indicating information (UHDM).With reference to Figure 13, for example, USE_ESN_BASED_PLCM is the field of the user mode of the expression PLCM that uses ESN (perhaps type 0), and its length is a bit.In one embodiment, PLCM_39 is the field that comprises by 39 bits of base station assigns, and has the length of 0 or 39 bit.PLCM_INCL is whether this field of expression PLCM_39 is present in the field among SCM (professional connection message) or the UHDM (general switch indicating information).

In another embodiment, for instance,, then the 3rd field PLCM_INCL is increased to SCM or UHDM if the value of the user mode field of USE_ESN_BASED_PLCM is " 0 ".In one embodiment, if the value of the user mode field of USE_ESN_BASED_PLCM for example is " 1 ", then omit the 3rd field.In addition, if the 3rd field PLCM_INCL is increased to this SCM, then the second field PLCM_39 is increased to this SCM or UHDM.This is that then the value of the user mode field of USE_ESN_BASED_PLCM is " 0 " because if the value of UHDM and the 3rd field PLCM_INCL is " 1 ".In one embodiment, if represent that the value of the first field USE_ESN_BASED_PLCM of the user mode of this USE_ESN_BASED_PLCM is " 1 ", if perhaps the value of the 3rd field PLCM_INCL is " 0 ", in SCM or UHDM, do not comprise the second field PLCM_39 so.

Therefore, in one embodiment of the invention, if the value of the first field USE_ESN_BASED_PLCM of the user mode of expression USE_ESN_BASED_PLCM is " 0 ", then this second and the 3rd field PLCM_39 and PLCM_INCL are increased to this SCM or UHDM.Therefore, according to the change situation of system, the present invention supports a kind of method that is used for portable terminal, and the method for the PLCM that will be produced by type 0 is changed into use is produced PLCM by the PLCM_39 of this base station assigns method.
